Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to automatic assembly equipment, and more particularly, for example,
The present invention relates to an automatic assembling device that allows a thrust metal to be grasped and rotated in an assembly process of an engine section so as to be automatically and easily inserted between a crankshaft and a cylinder block.

In an engine of an automobile or the like, linear motion of a piston, which is repeated at a considerably high speed, is converted into rotational motion of a crankshaft via a connecting rod. Therefore, a metal having excellent wear resistance is fitted to the sliding contact portion between the connecting rod and the crank shaft and between the journal and the cylinder block to suitably prevent the occurrence of wear or the like that is likely to occur at the sliding contact portion.
Further, a thrust metal formed of a semicircular thin plate is loaded between the boundary portion between the journal and weight of the crankshaft and the journal bearing portion of the cylinder block to prevent axial displacement of the crankshaft and The crankshaft is rotated well, and the crankshaft and the cylinder block do not come into sliding contact with each other to cause wear or the like.

By the way, conventionally, the assembling work of the thrust metal is generally performed manually by an operator. That is, the crankshaft journal is placed on the journal bearing portion of the cylinder block by hand, and then a semicircle formed at the boundary portion between the crankshaft journal and the weight and both side wall portions of the journal bearing portion. The assembling work is performed by inserting the thrust metal into the space defined by the groove.

The automatic assembling apparatus and the thrust metal supplying apparatus according to the present invention are basically constructed as described above, and the operation and effect thereof will be described below.

First, the storage unit 1 that constitutes the thrust metal supply device 12.
A predetermined number of thrust metals S are loaded in 4a and 14b. That is, in the storage portion 14a, if the grip portion 38a of the pressing member 38 is pulled in the direction opposite to the arrow,
The pressing member 38 is displaced in the direction opposite to the arrow against the elastic force of the spring 36 (see FIG. 2). Therefore, rails 32a, 32 provided inside the side plates 30a, 30b
The plurality of thrust metals S are housed between the supporting body 34 and the pressing member 38 so as to be mounted on the holding portion 3b.
When the pulling force on 8a is released, the thrust metal S is pushed toward the support 34 by the pushing member 38 that is pulled in the direction of the arrow via the spring 36. On the other hand, similarly in the storage portion 14b, a predetermined number of thrust metals S
Is loaded in the storage portion 14b.

Next, the thrust mechanisms S housed in the respective housing sections 14a, 14b are taken out by the take-out mechanisms 16a, 16b and the transport mechanism 1.
8a, 18b, feeding mechanism 20 and pushing mechanism 22a, 2
The thrust metal mounting table 138 of the automatic assembling apparatus 10 is gripped via 2b. In this case, since the paired mechanisms in which a and b are added to the same reference numerals respectively perform the same operation,
Hereinafter, the takeout mechanism 16a, the transport mechanism 18a, and the delivery mechanism 20.
Further, the pushing mechanism 22a will be described in detail, and the explanation of the other mechanisms 16b, 18b and 22b will be omitted.

As shown in FIG. 2, when the cylinder 44 constituting the take-out mechanism 16a is driven to displace the cylinder rod 44a in the arrow direction (vertically upward direction), the cylinder rod 44a
The thrust metal S, which is engaged with the push-up plate 42, ascends through the opening 40 of the first base 26 and abuts the support 34.
Is pressed upwards. Therefore, the thrust metal S pushed up via the push-up plate 42 passes through the opening 48 of the carrying plate body 46 constituting the carrying mechanism 18a and then fits into the groove 60a formed in the arm member 60. Reach

Therefore, the rotary drive source 56 that constitutes the transport mechanism 18a is driven. As shown in FIG. 1, when the rotary drive shaft 58 rotates in the arrow direction under the driving action of the rotary drive source 56,
An arm member 60 whose end is attached to the rotary drive shaft 58.
Rotates in the direction of the arrow with the thrust metal S fitted. Therefore, the thrust metal S is displaced in the direction of the arrow along the holder 49 and the grooves 50a and 50b under the rotating action of the arm member 60, and is conveyed through the opening 52 formed at the end of the plate 46. It falls on the rail 70a of the road 68.

Further, the delivery mechanism 20 is driven. As shown in FIG. 2, when the cylinder 62 is driven, the cylinder rod 62a
Is displaced in the direction of the arrow, the cylinder rod 62a
The delivery member 64 attached to the second base 28 is displaced along the inclination of the mounting plate 63. Therefore, the thrust metal S that has fallen into the transport path 68 is guided along the rail 70a by the plate portion 66a on one side of the delivery member 64 along the guide member 78.
It is pushed to the side. Eventually, the thrust metal S reaches the side of the guide member 78 via a stopper member (not shown). In this case, the take-out mechanism 16a, the transport mechanism 18a, and the delivery mechanism 20 are continuously driven, and a plurality of thrust metals S are aligned on the transport path 68 (see FIG. 2).

Next, the automatic assembly device 10 is moved to the thrust metal supply device 12 side. That is, after moving the moving unit 104 in the X-axis and Y-axis directions, the cylinder 112 is driven. When the cylinder rod 114 is displaced vertically downward under the driving action of the cylinder 112, the apparatus main body 116 suspended by the cylinder rod 114 is guided by the guide rails 108a and 108b.
It is guided by and descends. Therefore, the device body 11
The guide pins 178a to 178d of the positioning pins 170a to 170d attached to the No. 6 via the holding plates 168a and 168b are the hole portions 102a to 102d of the second base 28.
Is fitted to position the apparatus main body 116. Further, when the apparatus main body 116 is lowered under the driving action of the cylinder 112, the guide member 78 is fitted in the thrust metal mounting table 138 and the stopper means 146 is also installed.
a to 146d are locking members 8 arranged on the second base 28
2a to 82d are engaged. Therefore, the stopper means 14
Locking pins 154a to 1 provided on 6a to 146d
Since 54d abuts on the locking members 82a to 82d, the locking pins 154a to 154d are attached to the spring member 15a.
It is pressed in the direction opposite to the arrow in FIG. 4 against the elastic force of 6a to 156d. After all, the plates 148a to 148a
8d swings in the direction opposite to the arrow around the pin members 150a to 150d, and the claw members 152a to 152d are separated from the groove portions 140a and 140b.

After positioning the automatic assembling apparatus 10 on the thrust metal supplying apparatus 12 in this manner, the pushing mechanism 22a is driven. That is, when the rod 88 is displaced to the thrust metal mounting table 138 side under the driving action of the cylinder 86 constituting the pushing mechanism 22a, the pressing member 92 attached to this rod 88 causes the pressing member 92 to be opened in the guide side plate 74a. Enter into. Therefore, the thrust metal S aligned in the transport path 68 enters the groove 140 a of the thrust metal mounting table 138 by the pressing force of the pressing member 92, and the projection 1
It is mounted on 44a. The pressing member 92 has a rod 9
4 is attached, and locking portions 96a and 96b formed on the rod 94 are limit switches 100a and 100b.
It is possible to automatically and accurately attach the thrust metal S to the thrust metal mounting table 138 by driving the motor and detecting the position of the pressing member 92.

Therefore, the rod 162 is driven by the driving action of the cylinder 160a.
When a is displaced in the direction of the arrow in FIG. 4, the pressing plate body 164a engaged with the rod 162a is moved into the groove portion 166.
The thrust metal S that enters the a and is mounted on the protrusion 144a is pressed to fix the thrust metal S.

Next, the device main body 116 is driven by the cylinder 112.
Is displaced vertically upward, the engagement states of the locking pins 154a to 154d of the stopper means 146a to 146d and the locking members 82a to 82d are released, so that the plate 1
48a to 148d swing in the arrow direction by the elastic force of the spring members 156a to 156d. As a result, the claw members 152a to 152d project toward the groove portions 140a and 140b, and the thrust metal S inserted into the groove portions 140a and 140b is firmly held by the gripping mechanism 120 (see FIG. 3). .

Further, the moving unit 104 is displaced in the X-axis and Y-axis directions to move the automatic assembly apparatus 10 to the working position where the cylinder block 180 and the crank shaft 182 are arranged. In this case, as shown in FIG. 5, the journal 186 of the crankshaft 182 is mounted on the journal bearing portion 184 constituting the cylinder block 180, and the weights 188, 1 on both sides of the journal 186 are mounted.
Thrust metal loading portions 190, 190 are formed between the 88 and the journal bearing portion 184.

Therefore, the device body 11 is driven by the cylinder 112.
When 6 is displaced vertically from above the journal 186, the respective stopper means 146a to 146d engage with the weights 188 and 188 on both sides of the journal 186. Therefore, like the locking members 82a to 82d provided on the second base 28 that constitutes the thrust metal supply device 12, the locking pins 154a to 154d are attached to the weight 18 respectively.
8, 188, and is pressed in the direction opposite to the arrow (see FIG. 6). Therefore, the respective stopper means 146a to 146d are displaced in the direction opposite to the arrow against the elastic force of the spring members 156a to 156d, and as a result, the claw members 152a.
Through 152d are separated from the groove portions 140a and 140b. Next, when the cylinders 160a and 160b are driven to displace the rods 162a and 162b in the directions of the arrows in FIG. 6, the pressing plates 164a and 164b release the pressing action of the thrust metal S and the groove portions 166a and 166b.
Leave from.

In this way, the gripping action of the thrust metal S by the gripping mechanism 120 is released, and the projections 144a and 144b forming the thrust metal device base 138 are brought into contact with the journal 186, and then the insertion mechanism 118 is driven. To be done. That is, as shown in FIG. 4, the rotary drive source 1
When the rotary drive shaft 122a is rotated in the direction of the arrow by driving 22, the first gear 124, which is rotatably supported by the rotary drive shaft 122a, rotates, and the second gear 12 having a small diameter meshes with the first gear 124.
The third gear 128 rotates via 6. In this case, the first
The gear 124 and the third gear 128 have the same diameter, and the positions of the pin members 130a and 130b are equidistantly spaced from the centers of the gears 124 and 128, respectively. Therefore, under the driving action of the rotary drive source 122, the link 132 is displaced in the direction of the arrow through the first gear 124 and the third gear 128 in the state of being oriented in the vertical direction, and the plate body 134 fixed to the link 132 is fixed. Locking pin 1 planted at the lower end
36a and 136b are displaced in the groove portions 140a and 140b in the arrow direction (see FIG. 6). As a result, the groove 140
The thrust metal S inserted in the a and 140b is rotated along the curved shape of the groove portions 140a and 140b with one end engaged with the locking pins 136a and 136b, and the weights 188 and 188 and the journal bearings. Part 1
84 thrust metal loading sites 190, 190 forcibly inserted.

Then, the device main body 11 is driven by the cylinder 112.
6 is displaced vertically upward, the stopper means 146a
To 146d are separated from the weights 188 and 188, and the respective claw members 152a to 152d are provided in the groove portions 140a and 14d.
It projects to the 0b side. Further, after displacing the moving part 104 in the X-axis and Y-axis directions, as described above, the automatic assembling device 10 is positioned with respect to the thrust metal supply device 12, and the gripping mechanism 120 is used to move the new thrust metal S. The gripping work is performed.

In this case, according to the present invention, it is possible to reliably hold the component relatively thinly like the thrust metal S and smoothly incorporate the thrust metal S into the thrust metal loading portion 190. That is, the groove portions 140a and 140b corresponding to the shape of the thin plate-shaped thrust metal S are formed on the thrust metal mounting table 138, and the groove portions 140a and 140a are formed.
The thrust metal S fitted to 140b is gripped by the gripping mechanism 1
It is firmly held via stopper means 146a to 146d constituting 20 and pressing plate bodies 164a and 164b attached to the cylinders 160a and 160b.
Therefore, the thrust metal S does not drop from the thrust metal mounting table 138 or cause a displacement when the apparatus main body 116 is moved. Further, when the thrust metal mounting table 138 is made to grip a new thrust metal S, or when the thrust metal S is incorporated in the thrust metal loading portion 190, the locking members 82a to 82a.
The stopper means 146a to 146d are separated from the thrust metal S under the cooperation of d or the weight 188. As a result, it becomes possible to smoothly perform the work of attaching and detaching the thrust metal S to and from the thrust metal mounting table 138.
