Description

[Detailed description of the device] [Industrial applications]

The present invention relates to an assembly apparatus for vehicle body component parts in an assembly line of a vehicle body such as a driver's cab of an automobile, and a set of vehicle body assembly parts capable of easily and automatically positioning the components for welding work or assembly work. The present invention relates to an alignment positioning device.

[Prior art]

With regard to parts such as automobile body parts made of steel plates, the rigidity of one part is insufficient and the non-molded state remains, so it is necessary to combine multiple parts, but the combination position cannot be fixed automatically and as a result combination is impossible. Since such a situation may occur, it is necessary for an operator to manually perform the combined positioning of the parts.

[Problems that the device is trying to solve]

The above-mentioned conventional technique has the following problems. That is, in the case of a part whose combination position is not fixed due to insufficient rigidity, it requires manual work time to manufacture the combination member, and if the combination work is not within the reach of a person, it becomes impossible to manufacture and the work place is also There was a problem that it was widely needed and productivity was low.

[The purpose of the device]

The present invention was made in order to solve the above-mentioned problems, and even in the case of a component whose combination position is not fixed due to insufficient rigidity, it can be easily and inexpensively manufactured without manual labor, and production that enables automation is also possible. An object of the present invention is to provide a highly-combined positioning device.

[Means for solving the problem]

For the above-mentioned purpose, the present invention constitutes a link mechanism, an electromagnet is provided at one end of a lever of the link mechanism, and the first component is attracted by the electromagnet so that the second component is moved by the action of the link mechanism. The structure is such that it can be positioned at a predetermined combination position with the above parts. If the electromagnet is provided with a control means that is excited when the positioning operation of the link mechanism is started and is de-excited when the combination work after positioning is completed, the action of the electromagnet can be automatically controlled.

[Function of the device]

According to the above-mentioned means of the present invention, even if it is difficult to determine the combination position, the first component is temporarily held by the attracting action of the electromagnet, and the second component is kept in the predetermined position during the holding period. Allowed to be set by the operator. That is, the position A shown in FIG. 3 is the air cylinder 01 when the first component 12 of FIG. 2 is attracted to the electromagnet 07 at the position B.
Operation, the upper side of the drawing is pulled up and the retracted position is shown.
Since the first component 12 is retracted from the B position to the A position, the second component 13 does not interfere with the first component 12 on the assembling device (not shown) and is in the A position. It can be set between the first part 12 and the B position which are retracted.

[Examples of the present invention]

Hereinafter, the details of the present invention will be described with reference to an embodiment shown in the drawings. In FIG. 1, an air cylinder 1 which is an actuator having a cylinder rod 2 which is reciprocally driven with a predetermined stroke is fixed to a base 8, and a link joint 3 is connected to the cylinder rod 2. While lever 5
Is swingably connected to a base 8 via a lever fulcrum pin 11, and an electromagnet 7 is fixedly attached to one end of the base 8 and a sensor 6 is attached adjacent thereto. Further, a connecting member 4 is rotatably installed between the lever 5 and the link joint 3 via a lever joint pin 10 and a link joint pin 9, respectively. Next, the operation of this embodiment will be described below. As shown in FIG. 1, when the cylinder rod 2 of the air cylinder 1 is in the retracted position, the lever 5 is tilted slightly to the right from above in the drawing. At this time, the vehicle body components are in the required positions. Is not set. Next, as shown in FIG. 2, when the cylinder rod 2 extends and the connecting member 4 is in the vertical position in the drawing, the lever 5 is in the horizontal position, and the operator sets it in advance to the required position (between AB in FIG. 3). The electromagnet 7 provided on the lever 5 comes into contact with the surface of the plate-shaped first component 12 in the drawing, and is attracted to the first component 12 by the electromagnet that is energized and excited before the contact. Further subsequently, FIG. 3 shows a state in which the cylinder rod 2 is extended to the longest stroke. At this time, as shown in the drawing, the link 4 is displaced from the vertical position in FIG. 2 and tilted to the left side, and the lever 5 swings about the lever fulcrum pin 11 as the fulcrum by the lever joint pin 10 from the link joint pin 9 through the connecting member 4. Then, the first component 12 attracted to the electromagnet being excited is pulled up upward in the figure, and is also pulled up as a unit. The A position shown in FIG. 3 shows the position where the first component 12 of FIG. 2 is pulled up upward in the figure by the operation of the air cylinder 1 in the state where the first component 12 is attracted to the electromagnet 07 at the B position.
Since the first component 12 is retracted from the B position to the A position, the second component 13 does not interfere with the first component 12 and the first component 12 on the assembly device (not shown) is The operator can set it to the B position. The sensor 6 can detect that the electromagnet 7 is excited and attract the first component, and can also indicate that the component is attracted to a display member (not shown). Therefore, the operator sees the display and the first component 12 is in the retracted position, and the second component 13 does not interfere with the first component 12.
Can be set on the assembly device. On the other hand, if a detecting means for detecting that the first component 12 is pulled up to the position A is provided on the device and the excitation of the electromagnet 7 is released by the signal of the detecting means, the first component 12 is released.
Can fall on the second part 13 in the B position and can be assembled (the first part 12 is on the second part 13). Further, by automatically controlling the excitation and de-excitation of the electromagnet 7 and the operation of the air cylinder 1, the first component 12 once pulled up is lowered onto the second component 13 while being attracted by the electromagnet 7 (the first component 12). The state of the first part 12 in FIG. 2) The first part 12
It is also possible to position the second component 13 in a state in which the second component 13 is attached by suction. Of course, it is also possible for an operator to visually confirm the position of the component and to excite and demagnetize the electromagnet.

[Effect of device]

As described above in detail, according to the present invention, the link mechanism is used to equip one end of the lever with the electromagnet so that the electromagnet is excited and the component is attracted when necessary. It is not necessary for the operator to manually set the second part 13 while holding it by hand and lifting it upward in the drawing, and a hand on the assembly device (not shown) Since there is no need for the manual work as described above even at a position that cannot be reached, there is an effect that the work can be automated without considering positional restrictions.
