Description

Technical Field

[0001] This utility model relates to the technical field of chain production equipment, and in particular to an assembly device for an automated chain assembly line. Background Technology

[0002] Chains are commonly used components in the mechanical field, often used for conveying and transmission. They typically consist of inner links, with two adjacent inner links connected by two outer links. The outer links are connected to the inner links by pins, which are usually riveted or pressed together by retaining rings.

[0003] Existing chain assembly methods generally employ manual assembly, followed by hydraulic press pressing the pins together. However, this assembly method is inefficient. A chain assembly device, patent application number CN202123348622.8, includes a workbench with a conveying device on its horizontal center line. Positioning blocks are spaced apart on the conveying device. From right to left, the top surface of the workbench has a mechanical clamp and a pressure device, located on either side of the conveying device.

[0035] The working process of this utility model:

[0036] In the operation of this utility model, an assembly device for an automated chain assembly line utilizes a vision alignment system 18 to guide a six-axis robot to pick up an outer chain link and place it on an outer chain link support 11, ensuring that the rear end of the outer chain link 7 (including an outer chain plate and two pins on the outer chain plate) coincides with the front reference line 19. Then, a drive cylinder 44 is activated, causing the drive pin 47 to extend between the two pins. Next, a servo motor 146 is activated, driving a gear 48 to rotate and move along a rack 49. This, in turn, causes the slide 143 to move via the servo motor 146. The slide 143, through the drive pin 47, moves the outer chain link 7 backward a certain distance, aligning the front end of the outer chain link 7 with the rear reference line 19. Finally, the six-axis robot picks up another outer chain link 7 and places it back on the outer chain link support 11, ensuring that the rear end of the outer chain link 7 coincides with the front reference line 19. Line 19 overlaps, and then through the cooperation of X-axis drive mechanism 22, Y-axis drive mechanism 23 and Z-axis drive mechanism 24, the sleeve 262 is driven to fit onto the inner link 8 placed on the corresponding inner link receiving platform 25. Then, the electromagnet 263 is activated to attract and fix the inner link 8. Then, through the cooperation of X-axis drive mechanism 22, Y-axis drive mechanism 23 and Z-axis drive mechanism 24, the sleeve 262 carrying the inner link 8 is driven to move to the assembly position to fit the inner link 8 onto the corresponding pins of two adjacent outer links. The above operation is repeated to achieve the fitting connection between the outer link 7 and the inner link 8. Driven by the chain translation unit 4, it enters the support guide rail on the press 3. When it runs to the pressing position, a six-axis robot grabs an outer link plate and fits it onto the pins of the two outer links fitted with the inner link 8. Then, the press 3 is started to perform the pressing operation.

[0037] The baseline 19 includes a baseline straight line 191 and a baseline arc 192. The baseline arc 192 is used for the outer chain plate with an arc-shaped end, and the baseline straight line 191 is used for the outer chain plate with a straight end.

[0038] After the inner link 8 on the inner link receiving platform 25 is removed, a four-axis robot grabs the inner link 8 and places it on the inner link receiving platform 25. The two sleeves of the inner link 8 are respectively fitted onto the two positioning shafts 256. Then, the two piston rods of the double-headed cylinder 252 are activated to extend and drive the two positioning shafts 256 to move in opposite directions, so that the positioning shafts 256 tension and position the inner link 8. When the inner link 8 is removed, the two piston rods of the double-headed cylinder 252 retract and drive the positioning shafts 256 back to their original positions.

[0039] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
