Description

[Detailed Description of the Invention] [Purpose of the Invention] Industrial Application Field The present invention relates to a blade assembly device for a torque converter shell.

Conventional Technology Conventionally, the task of assembling a blade to a torque converter shell has been done manually.

These shells and blades are press-formed thin plates, and often have burrs attached to their fractured surfaces, which is dangerous during manual assembly work.

In addition, the work of assembling the blades to the shell is a simple task, and requires heavy labor as it requires assembling a large number of blades in a single hour, and labor costs are high, making it uneconomical.

Problems to be Solved by the Invention In order to improve productivity and obtain an inexpensive torque converter, the inventor of the present invention decided to use an industrial robot to assemble the blades to the seat.

By the way, in order to assemble a blade to a shell using an industrial robot, it is necessary to position the shell with high precision. In other words, it is necessary to assemble a large number of blades to the shell,
Each blade has a plurality of protrusions, and it is necessary to ensure that these protrusions are inserted into radial slits in the shell.

The present invention provides a blade assembly device for a torque converter shell that can accurately and quickly assemble a blade by accurately and firmly holding the slit position of the shell supplied to the working position. The purpose is to provide

[Structure of the invention] Means/effect for solving the problem In order to achieve the above object, the blade assembly device for a torque converter shell of the present invention is designed to assemble a blade to a shell for an industrial robot at a blade assembly position. a collector chuck inserted into the central opening of the shell for relative rotation; a detector attached to a blade gripper attached to the wrist of the industrial robot to detect a predetermined blade attachment slit in the shell; a pin attached to the wrist and inserted into the detected slit to rotate the shell to a predetermined position; after the shell has rotated, the shell is fixed in the opening by the collect chuck and transferred upward; It is characterized by comprising: a positioning plate that abuts and fixes the outer circumferential portion; and;

To explain in more detail, the collector chuck is inserted into the central opening of the shell that has been conveyed to the working position by a conveyor means, so that it can rotate freely.
After raising it to a predetermined height, the position of one blade assembly slit within a specified range is detected by a detector such as an optical sensor. The position information of the slit is given to the industrial robot, and the pin attached to the wrist of the robot is inserted into the slit, and by moving the pin, the shell is rotated, and the slit is moved to a predetermined position. let Next, the shell is fixed by moving the mandrel built into the collect chuck downward by an air cylinder and expanding the chuck part of the collect chuck in the radial direction.
The shell is raised using another air cylinder until it hits the positioning plate, the outer periphery of the shell is also fixed, and the industrial robot starts assembling the blade.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In FIGS. 1 and 2, the shell 4 is conveyed to a predetermined position by an appropriate conveyor means while being placed on a pallet 3.

Next, the support plate 7 is raised along the guide 6 by the air cylinder 5 of the shell positioning device 2,
The collection chuck 10 is passed through the opening 8 of the pallet 3, inserted into the opening 9 of the shell 4, and the shell 4 is lifted up to the position 4a.

Thereafter, as shown in FIG. 3, the optical sensor 13 attached to the side wall of one of the plurality of grippers 12 attached to the wrist of the industrial robot 1 shown in FIG. The position of a preset slit, for example slit 15, among the mounting slits 15, 16, and 17 in a prespecified search range X is detected.

When the position of the slit 15 is detected, the position information is given to the industrial robot, and as shown in FIGS. 6 and 7, the pin 14 attached in parallel with the optical sensor 13 is inserted into the slit 15.
The industrial robot 1 rotates only the shell 4 to the specified position, and collects the chuck 10.
The mandrel 19 of the shell 4 is moved downward by the air cylinder 18, and the chuck portion of the collect chuck 10 is expanded in the radial direction to maintain the inner diameter of the opening 9 of the shell 4, and then the core bar 19 is moved downward by the air cylinder 18, and the inner diameter of the opening 9 of the shell 4 is maintained. A positioning plate 22 that raises the shell 4 and is attached to the reference plate 21 by an air cylinder 20
Press the outer diameter part of the shell 4 against it to fix it.

With this, the positioning and fixing work of the shell 4 is completed, and the industrial robot 1 moves the shell 4 and the
The blades 23 having the shape shown in the figure are grabbed one by one by the claws of a plurality of grippers 12 from a blade positioning stand (not shown) and inserted into the positioned slits 15, 16, 17 of the shell 4.

It goes without saying that if the shape and dimensions of the shell and blade change, the collection chuck, reference plate, and positioning plate can be replaced.

[Effect of the invention] The position of the slit in the shell on the pallet conveyed by the conveyor means is shifted from the predetermined position, and after rotating the slit to the predetermined position, the central opening of the shell is Since the outer periphery of the shell is fixed, the slit of the shell is always in the correct position, and there is no shift of the shell due to the load applied when assembling the blade, making it easier to assemble the blade and ensuring stable quality. It becomes possible to continuously produce several items. Therefore, compared to manual work, productivity is improved and an inexpensive torque converter can be provided.
