Description

Technical Field

[0003] The outer chain link is mainly composed of an outer link plate and a pin shaft. In the prior art, the press-fitting of the outer chain link requires manual placement of the outer link plates one by one in a press-fitting plate, manual positioning of the pin shaft, and then press-fitting. This press-fitting method not only has low work efficiency, but also low manual operation safety, and cannot meet the use requirements.

[0028] Working process of the present invention: During the operation of the pin shaft rotation adjustment device for assembling the outer link plate of the chain of the present invention, the pin shaft is placed into the corresponding pin shaft slot 32 by a manipulator, and then the multi-directional driving mechanism 21 is started to drive the clamping jaws 22 to run to the pin shaft and clamp it, and then the pin shaft is removed from the pin shaft slot 32, and then the two clamping jaws 22 are driven to rotate one by one by the rotating driving mechanism 24, and the direction of the hole at the end of the pin shaft is detected by the camera 23. When the direction of the hole of the pin shaft reaches the required direction, the corresponding clamping jaw 22 stops rotating.

[0029] When the rotation drive mechanism 24 is working, the annular electromagnet 2454 in front is stopped. At this time, the corresponding annular seat 2458 drives the sliding sleeve 2457 to move downward under the action of the spring 2456. The sliding sleeve 2457 drives the connecting head 2453 to move downward and press on the friction head 221 in front. Then the reduction motor is started to drive the two transmission shafts 2452 to rotate through the cooperation of the synchronous belt 2462, the active synchronous wheel 2463 and the two driven synchronous wheels 2464. The corresponding friction head 221 drives The clamping jaw 22 rotates, and the clamping jaw 22 drives the pin shaft grasped by it to rotate, so as to adjust the direction of the hole of the pin shaft. When the camera 23 detects that the direction of the hole reaches the required direction, the reduction motor stops, and the annular electromagnet 2454 in the front works and attracts the corresponding attracted body 2455. The attracted body 2455 drives the sliding sleeve 2457 to move upward through the annular seat 2458. The sliding sleeve 2457 drives the connecting head 2453 to disengage from the corresponding friction head 221, and then stops the annular electromagnet 2454 in the rear. At this time, the corresponding annular seat 2458 drives the sliding sleeve 2457 to move downward under the action of the spring 2456, and the sliding sleeve 2457 drives the connecting head 2453 to move downward and press on the friction head 221 in front, and then the reduction motor is started to drive the two transmission shafts 2452 to rotate through the cooperation of the synchronous belt 2462, the active synchronous wheel 2463 and the two driven synchronous wheels 2464, and the corresponding friction head 221 drives the clamping claw 22 to rotate, and the clamping claw 22 drives the pin shaft grasped by it to rotate, so as to realize the pin alignment. The direction of the hole of the shaft is adjusted. When the camera 23 detects that the direction of the hole meets the requirement, the reduction motor stops, and the annular electromagnet 2454 at the rear works and attracts the corresponding attracted body 2455. The attracted body 2455 drives the sliding sleeve 2457 to move upward through the annular seat 2458. The sliding sleeve 2457 drives the connecting head 2453 to disengage from the corresponding friction head 221, and then the multi-directional driving mechanism 21 drives the clamping jaw 22 to place the pin shaft into the corresponding pin shaft slot 32, and then drives the clamping jaw 22 to return to its position.
