Abstract

PURPOSE:To automatically perform substantial assembly work, by holding two assembly parts of different kind with fingers and supporting levers operated interlocking to a piston of an actuator and automatically performing all of the assembly work through action of the actuator. CONSTITUTION:Trapezoidal links 13a, 13b are secured to a point end part 11 of a robot and a holding link 14 is rotatably connected. Replaceable fingers 15 are mounted to the link 14 and formed to a holding shape. While a major actuator 16 is secured by a peripheral wall 16a to the links 13a, 13b. A minor actuator 22 is integrally mounted toa structure 29, and the structure 29 is vertically moved by action of a pneumatic cylinder 12 to vertically move supporting levers 28a, 28b. If the structure 29 is pressed downward, a slide pin 5 is integrally formed with an insertion jig 6, and the pneumatic cylinder is operated to build a pin 5 in the boots of a brake.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention G: l [Related to automatic assembly device (Special
The device on the stand allows the parts of 211111 to be held and assembled without any movement.

Conventional assembling devices have one set of fingers for gripping parts and carry out one set of conveyance, but these fingers are arranged around the circumference of parallel documents and handle two types of parts. I was unable to hold it stably, but I was unable to do the assembly work of assembling the two parts together.

The present invention automatically assembles two types of parts, which was conventionally done mostly by hand, by skillfully inserting one part into another. The aim is to automate assembly work.

When assembling the brake of automatic seal parts, when assembling the slide bin to the brake body, use the rubber boots [
Because the inner diameter of the boot is smaller than the outer diameter of the slide bin, it is extremely difficult to insert the slide bin into the boot, and the slide bin must be inserted manually. I was doing the assembly.

Invention 11 Insert the slide bin into the rubber boot T
The boot is inserted into the hole in the brake body in advance, and then a large finger that opens and closes by aligning the piston stomach and -11 of the large actuator, which is operated by air pressure, and a small 7 Support levers that engage with the piston rond of the Tachiator to open and close are arranged in series, and the support levers hold the slide bin vertically, and insert a large finger (more conical insertion jig) into the slide bin. Fit the insertion jig into the hole, integrate the insertion jig and the slide bin, and move the conical insertion jig into the boot (by inserting the insertion jig into the rubber boot). The slide bin is securely held and assembled in the boot by expanding the inner diameter of the slide bin and stopping the slide bin at a fixed position. Circle # for smaller than outer diameter
1: Insert from the conical side using a shaped insertion jig, expand the inside of the boot, and then move and assemble the slide bin. In this way, by assembling the slide bin together with the brake body (rubber boot), the automation of brake assembly work is greatly advanced.

1 to 6 (for further explanation, l is the brake body, 2 is the slide bin holding part, 3a is the
, 3b is a rubber boot, 4 is a mounting screw, 5 is a hollow slide bottle, and 6 is a conical insertion jig with stepped portion 6af.
It fits into the hollow part 5km of the slide bin.

This page explains the assembly work of boots and slide bin.
As shown in Figure 8 (2 is the slide bottle holding part,
Grooves 2a and 2b at the inner end of the through hole 20 are pre-booted 8m,
8b from both ends. Next (the slide bin 5 is attached to the brake body 2 and the boot 8 & nail are inserted), but the outer diameter β of the slide bin is β>- compared to the inner diameter dimension a of the boot, and the boot Since it is made of rubber, it is flexible and cannot be inserted directly.Therefore, the automatic assembly device of the present invention is used to assemble it, and the process will be described below. 4, the through hole 51L of the slide bin (step part 6 & of the conical insertion jig 6 is inserted into the through hole 5 & r using this device, the slide bin and the insertion jig are integrated, and then the (brake main body) (Attached boots 8ak: Insert the insertion jig using this device, completely penetrate the nails of boots 8a and 3bTt, and feed with a WI machine to a certain point where the convex part of the boot enters the groove of the slide bin. Yes.In this way, the automatic assembly device is used to carry out the work beyond the process of assembling the parts in close contact with the slide bin and then removing the insertion jig 6. IOG go automatic assembly device, 11 is the tip of the robot (not shown), 12
G Go air cylinder, 12m No. Go air cylinder axis 1
3m and 18b are trapezoidal links that connect the tip part 11 of the robot.
11L, 141: J clamping link 14a, 14
It is made into a shape 2 (original shape, square shape, etc.) that should be clamped with freely rotatable connecting fingers d and 15G with freely replaceable fingers. 16 is the large actuator rFla! 16a&: The trapezoidal links 18a and 18b are closely observed.

17 is a spring in the actuator, 18 is a piston, 19 is a piston rod, 20 is a clamping link 14m, a contact plate that engages with 14b, 21& and 21b are air pressure intake and exhaust ports, 1, 22 are small Akche *-, 23 is a spring,
24 is a screw, 25 is a piston rod, 26 is a small contact &, 27a,! ! ? b is 28m at the intake and exhaust port of the small actuator! 8b is a support lever. ! ! Reference numeral 9 denotes a structure to which the actuator 22 is integrally attached, and the action of the air cylinder 12 (from the air cylinder axis 121
Correspondingly to the vertical movement of the support levers 28m and 28b, the support levers 28m and 28b are vertically moved regardless of the trapezoidal links 18m and 18b and the clamping links 14.

In the above configuration, the Ryo-5 main body 11 is moved and stopped above the boxes, etc. (slide bins 5 arranged in advance), and the air pressure is discharged from the exhaust port 27 & of the small actuator 22, and the air pressure is released from the air pressure 27b. supply, actuating the piston upwards and causing the small contact plate 26 to rise.
As shown in figure 5, the slide bin is supported by lever 28m.
It is clamped at 28b. Next, the arm main body 11 is moved above the insertion jig 6, and the large 7-piece cutter 16 &: air pressure is sucked and exhausted from the piston 18. The piston rod 19 is operated, the contact plate 20 is raised, and the ends 14m and 14b of the clamping link 14 are rotated by half a turn, and the end 15 of the clamping link is rotated.
(Hold the conical insertion jig 6'fr:.Next, actuate the air cylinder 11t and push down the structure 29ft to which the small 7 cutter is attached from the air cylinder shaft 12a&: tq&f Ii the slide The pin 5 and the insertion jig 6 are fitted together. Next (the insertion part 80, which is a combination of the slide bin and the insertion jig, acts a large actuator to loosen the finger 15 and actuates the air cylinder 12. At least if the structure 29Tt is pushed downward, the brake body for assembly with the boot inserted into the brake body by a conveyor etc. will be located below the inserted part, and if the air cylinder is not operated The tool passes through the rubber boot F. Therefore, the slide bin 5
The slide bin can be assembled into the boot of the brake body as shown in FIG. 4 (E) (T), and the insertion jig 6 is removed after assembly is completed.

As described above, the present invention provides a me body in which two 7-actuator units are arranged in series at the end of the robot, and two different types of assemblies can be assembled using a finger and a support lever that operate in conjunction with the piston of the actuator. This is a device that holds parts for use and connects and assembles the parts by the action of an actuator.
The automatic assembly machine performs the assembly work that conventionally had to be done by hand, and is extremely effective in the assembly work of parts.
