[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a welding machine suspension device used for suspending a welding wire feeding mechanism provided in a welding machine such as a semi-automatic welding machine.

[0002]

[Prior art]

 As shown in FIG. 8, a welding machine, for example, a semi-automatic welding machine, includes a welding power source 81 installed on the floor, a welding torch 82, a wire reel 84a in which a welding wire 83 is coiled, and a wire feeding motor (not shown). And a welding wire feeding mechanism 84 for feeding the welding wire 83 to the welding torch 82. The welding torch 82 and the welding wire feeding mechanism 84 side are connected to the welding power source 81 via a power cable 85, and the welding wire feeding mechanism 84 and the welding torch 82 are connected to a flexible conduit 86. The welding work can be performed at a place away from the welding power source 81.

When such a semi-automatic welding machine is used in a factory, it is preferable to suspend it from above so that the welding wire feeder mechanism 84 does not interfere with welding work and transportation of goods, jigs and the like. It is common.

Conventionally, as a suspending device for a welding machine used for suspending the welding wire feeding mechanism 84 of the semi-automatic welding machine from above, for example, a cantilever horizontally installed on a wall surface 90 of a factory. A beam 91 and a feeding mechanism suspending mechanism 92 provided so as to be movable along the cantilever 91 are provided, and a welding wire feeding mechanism is provided to the feeding mechanism suspending mechanism 92 via a wire 93. By suspending 84, it is possible to easily move the welding wire feeding mechanism 84 at a place apart from the welding power source 81 installed adjacent to the wall surface 90 and within the length of the cantilever 91 to perform welding. There were things that made it possible to do the work.

[0005]

[Problems to be solved by the device]

 However, in such a suspending device for a welding machine, the range in which welding work can be performed is limited to the length of the cantilever beam 91 and near the cantilever beam 91, and the length dimension of the cantilever beam 91 is increased. When the work range is widened, the cantilever beam 91 may become an obstacle when carrying products or jigs by a crane, for example, and welding of uneven workpieces (base metal) There were problems such as not being able to easily deal with.

Further, when a plurality of welding wire feeding mechanisms 84 are hung on the cantilever 91, the respective power supply cables 85 connected to the respective welding wire feeding mechanisms 84 are entangled with each other and are welded individually. Since there is a risk of hindering the work, the conventional welding machine suspending device has a problem that only one welding wire feeding mechanism can be suspended in one device. It has been a conventional problem to solve the above problem.

[0007]

[The purpose of the device]

 The present invention was made in view of the above-mentioned conventional problems. For example, welding work can be carried out without hindering the transportation of products and jigs by the crane and without imposing a heavy burden on the operator. The range of the welding wire can be greatly expanded, and the vertical position of the welding wire feeding mechanism can be easily changed according to the unevenness of the workpiece (base material). It is an object of the present invention to provide a suspending device for a welding machine, which can carry out individual welding operations without any trouble even if the mechanism is suspended.

[0008]

[0009]

[Function of the device]

 In the suspending device for a welding machine according to the present invention, when the sliding beam is slid and extended toward the tip end of the rotating beam by the sliding beam driving means, the slidable beams are respectively suspended by the plurality of feeding mechanism suspending mechanisms. The welding wire feeding mechanism and the welding torch connected to the welding wire feeding mechanism move to the positions separated by the amount of the movement of the sliding beam. It will spread without burden. When the rotating beam is rotated in this state, the welding wire feeding mechanism and the welding torch also rotate and move, respectively, which further expands the range in which welding work can be performed. .

In addition, for example, when a product or a jig is transported by a crane near the suspending device for the welding machine, the sliding beam is moved to the base end side of the rotating beam by the sliding beam driving means. By sliding it in and retracting it, and rotating the rotating beam in the appropriate direction and at the appropriate angle, it is possible to avoid obstructing the transportation route and to carry it without any hindrance. .

Further, in the suspending device for a welding machine according to the present invention, when there is a large unevenness in the workpiece (base material), the suspending mechanism for the feeding mechanism causes the welding wire feeding mechanism to move vertically. When moved, the welding operation will be carried out without being restricted by the unevenness of the work piece.

[0012] Furthermore, since each cable connected to the welding wire feeding mechanism suspended in each of the plurality of feeding mechanism hanging mechanisms is individually guided by the cable guiding mechanism, these cables are The welding work can be performed without any hindrance, because they do not get entangled with each other.

In this embodiment, a case where the welding machine is a semi-automatic welding machine is shown as an example, and shown in the drawings. The semi-automatic welding machine is equipped with a welding power source 61 provided adjacent to the wall surface 60 in the factory, a welding torch 62, and a wire feeding motor (not shown), and feeds the welding wire to the welding torch 62 at a constant speed.

In addition, the welding wire is fed to the welding torch 62 via the flexible conduit 66.

As shown in FIGS. 1 and 2, a device for suspending the welding wire feeding mechanism 64 of the semi-automatic welder, that is, the suspending device 1 for a welder is a base provided on a wall surface 60 in a factory. 4, a rotating beam 6 horizontally mounted, a sliding beam 7 provided below the rotating beam 6 and along the longitudinal direction thereof, an electric trolley 20 as a sliding beam driving means, and this sliding beam. It is mainly composed of a feeding mechanism suspension mechanism 30 for suspending the welding wire feeding mechanism 64 provided in FIG.

The rotating beam 6 is made of I-shaped steel, and its base end portion is attached to a beam mounting bracket 4a provided at the lower end portion of the base 4 via a vertical bolt 4b to rotate in the horizontal direction. I am able to do it. A stay 2 is provided between the hinge 4c provided at the upper end of the base 4 and the tip of the rotating beam 6 so as to rotate together with the rotating beam 6, and the stay 2 is equipped with the stay 2. By properly operating the turnbuckle 3, the turning beam 6 is prevented from bending.

The sliding beam 7 has substantially the same overall length as the rotating beam 6, and as shown in FIG. 5, is made of I-shaped steel like the rotating beam 6. On both sides of the base end portion, roller holding plates 9 and 9 extending toward the rotating beam 6 via base plates 8 and 8 fixed between the upper and lower flanges 7A and 7B are provided so as to face each other. In addition, rollers 12 and 12 supported by roller shafts 11 and 11 via bearings 10 (10) are provided inside each of the extended portions of the roller holding plates 9 and 9. .

The electric trolley 20 as the sliding beam driving means is provided at the tip of the rotating beam 6 as shown in FIGS. 3 and 4. This electric trolley 20 is attached to a block 22 fixed to the tip of the rotating beam 6 via a pin 23 and a pair of plates 24, 24, and the rollers 21, 21 of the electric trolley 20 are attached to the sliding beam 7. The lower surface of the upper flange 6A is abutted on the lower surface of the upper flange 7A with the web 7C interposed therebetween, and the rollers 12, 12 extended toward the rotating beam 6 are interposed with the web 6C of the rotating beam 6 interposed therebetween. The sliding beam 7 is slid along the longitudinal direction of the rotating beam 6 without causing a heavy burden on the operator by the operation of the electric trolley 20, that is, It is designed so that it can be extended from the tip. Further, roller bearings 13 and 13 that come into contact with the upper surface of the lower flange 6B of the rotating beam 6 are provided inside the roller holding plates 9 and 9 on the sliding beam 7 side, respectively, and the base end portion of the sliding beam 7 is provided. By providing the roller bearings 14 and 14 which contact the both side surfaces of the lower flange 6B of the rotating beam 6, respectively, the sliding beam 7 can be slid with respect to the rotating beam 6 without rattling. Further, the sliding range of the sliding beam 7 is regulated by providing stoppers 15 and 16 near the tip of the rotating beam 6 and near the base end, respectively.

As shown in FIG. 6, the suspension mechanism 30 for the feeding mechanism includes a bearing holder 31 having a substantially concave front shape that fits with the lower flange 7 B of the sliding beam 7. At the same time, it is provided with a hanging bracket 36 attached to the welding wire feeding mechanism 64 side.

The bearing holder 31 is placed on the inside of each of the opposing wall portions so as to contact the upper surface of the lower flange 7B with the web 7C in between when the bearing holder 31 is fitted to the lower flange 7B. It is provided with roller bearings 32, 32 in contact with each other, and is movable along the lower flange 7B of the sliding beam 7. In this case, the stopper 17 is provided on the web 7C at the tip of the sliding beam 7 to prevent the bearing holder 31 from falling off the sliding beam 7.

Further, a pair of pulley holding plates 33, 33 extending downward are provided on the bottom of the bearing holder 31, and a pin 34 supports the pulleys 33, 33 between the plates 33, 33. The pulley 35 is provided.

On the other hand, the hanging bracket 36 is fixed so as to project from the upper end of the reel storage case 64b of the welding wire feeding mechanism 64, and a bracket pulley 37 is provided on the projecting portion. is there.

Then, in the suspension mechanism 30 for the feeding mechanism, the wire 39 having one end fixed to the wire fixing pin 38 on the bearing holder 31 side is sequentially pulled to the bracket pulley 37 and the bearer holder pulley 35. The welding wire feeding mechanism 64 can be moved in the longitudinal direction of the sliding beam 7 and can be moved in the vertical direction by hanging the wire 39 and tying the other end of the wire 39 to the wire stopper 64c provided in the reel storage case 64b. It is possible to hang it.

In this embodiment, the welding machine suspension device 1 is provided with three sets of the feeding mechanism suspension mechanism 30 having the above-described configuration, which enables simultaneous welding at three locations. I am trying.

Further, the suspension device 1 for a welding machine is made of C-shaped steel forming a cable guide mechanism 40 on both sides of each of the rotating beam 6 and the sliding beam 7, as shown in detail in FIG. The two cable rails 41, 41 are attached to each other via the rail mounting member 43 so that the groove portion faces downward. The cable guide mechanism 40 is also configured on these cable rails 41, 41. By engaging the plurality of rollers 42 with rings with each other and suspending the power supply cable 65 on each ring portion, the power supply cable 65 can be attached to the power supply cable 65 during simultaneous welding work at a plurality of locations. This prevents the foot from being caught, the power supply cave 65 from being caught by the object to be welded (base material) W on the floor surface, and the power supply cables 65 from being entangled with each other.

Next, a description will be given of how welding is performed by the semi-automatic welding machine in which the welding wire feeding mechanism 64 is suspended by using the above-described welding machine suspension device 1.

First, in FIG. 7, the rotary beam 6 is rotated within the range from the position A to the position C near the wall surface 60, and is aligned with the direction of the welding position (position B in this case) (FIG. 7 is indicated by a solid line).

Here, when welding the workpiece (base material) W on the left side of FIG. 1, the electric trolley 20 is operated to slide the sliding beam 7 to the left side of FIG. 1 (upper side in FIG. 7). , The operation of the electric trolley 20 is stopped at the time when the sliding beam 7 is extended from the tip of the rotating beam 6 (the state shown by the chain double-dashed line in FIG. 7, that is, the state shown in FIG. 1), 7 is fixed to the rotating beam 6. At this time, since the roller holding plates 9 and 9 come into contact with the stopper 15 on the tip side of the rotating beam 6, the sliding beam 7 does not drop off from the rotating beam 6 and the sliding beam 7 moves when the sliding beam 7 moves. Does not burden the worker at all.

Next, the suspension mechanisms 30 for each feeding mechanism are moved to appropriate positions on the sliding beam 7 to bring them to the state shown by the solid line in FIG. 1, and then the welding torch 62 is operated to perform individual welding. Start.

At this time, the power supply cable 65 connected to each welding wire feeding mechanism 64 is suspended by the cable rails 41, 41 (the power supply connected to the welding wire feeding mechanism 64 on the right side of FIG. 1). Since only the power cable 65 is hung on the lower flanges 6B and 7B of both beams 6 and 7, the power cable 65 does not catch on the workpiece W or the like and the welding wire is fed. The mechanism 64 can be moved so that the operator does not get caught during work, and the cables 65 do not get entangled with each other. Further, since the bearing holder 31 of the feeding mechanism suspension mechanism 30 abuts on the stopper 17 at the tip of the sliding beam 7, the feeding mechanism suspension mechanism 30 cannot fall off the sliding beam 7. Absent.

When continuously welding the workpiece W from the left side of FIG. 1 to the right side of FIG. 1, welding is performed by appropriately moving the suspension mechanism 30 for the feeding mechanism on the left side of FIG. On the right side of FIG. 1 of the workpiece W, the electric trolley 20 is operated to move the sliding beam 7 to the right side of FIG. 1, and the suspension mechanism 30 for the feeding mechanism is appropriately moved on the right side of FIG. 1 to perform welding. I do. At this time, since the roller holding plates 9, 9 come into contact with the stopper 16 on the base end side of the rotating beam 6, the sliding beam 7 does not collide with the base 4.

During this period, for example, when the workpiece W has unevenness with a large height difference, the wire 39 of the feeding mechanism suspension mechanism 30 is pulled to raise the feeding mechanism suspension mechanism 30. It can be dealt with.

Hereinafter, the rotating beam 6 is appropriately rotated within the range from the position A to the position C shown in FIG. 7 and the above operation is repeated, so that the welding is performed at any position within the semicircle of FIG. It can be performed.

During the above-described operation, the order of the rotation of the rotating beam 6, the sliding of the sliding beam 7, and the movement of the feeding mechanism suspension mechanism 30 may be appropriately changed.

During this work, if it becomes necessary to carry products, jigs, etc. near the workpiece W by a crane (not shown), for example, once the rotating beam 6 is moved to the wall surface shown in FIG. It is possible to avoid obstructing the transportation path by rotating the sliding beam 7 to the proximal positions A and C on the 60 side or sliding the sliding beam 7 toward the proximal end side of the rotating beam 6 and retracting it.

The detailed configuration of the welding machine suspension device 1 according to the present invention is not limited to the above-described embodiment, and other configurations, for example, the suspension mechanism 30 for the feeding mechanism, may be used. It is also possible to use an electric hoist.
