The working procedure of the split ring 6 assembly device in this embodiment is briefly described below:

the vibration plate 11 vibrates and feeds the split ring 6 into the accommodating groove 151 of the receiving block 15 through the straight groove 13 of the vibrating arm 12. The second lifting mechanism 17 drives the stop block 16 to extend and insert into the opening 63 of the first split ring 6 in the straight slot 13 for blocking.

The recognition means 2 recognizes whether the current recognition surface of the circlip 6 in the reception groove 151 coincides with the target surface. If the clamping angles are consistent, the rotating clamping jaw 311 of the first cutting assembly 31 is lifted by the first lifting mechanism 312, then rotates by 60 degrees by the swinging mechanism 313, and finally descends by the first lifting mechanism 312 and is placed on the fixed seat 321 of the second cutting assembly 32. If the rotation clamping jaw 311 is inconsistent with the rotation clamping jaw, the circlip 6 is turned over and rotated before being placed on the fixed seat 321 after the circlip 6 is clamped.

After the circlip 6 is placed on the fixed seat 321, the rotating jaw 311 is opened and the translation mechanism 324 of the second blanking assembly 32 is operated to avoid interference between the rotating jaw 311 and the fixed seat 321. The first lifting mechanism 312 ascends, the swing mechanism 313 reversely rotates by 60 degrees, the first lifting mechanism 312 descends, and material receiving is started. The second elevating mechanism 17 drives the stopper 16 to descend, and the first circlip 6 in the straight groove 13 is released and conveyed into the accommodation groove 151.

The horizontal driving assembly 44, the vertical driving assembly 45 and the clamping assembly 46 act to control the clamping mechanism 41 to clamp the split ring 6. At this time, the circlip 6 is not deformed.

The vertical drive assembly 45 drives the clamping mechanism 41 to the first assembled height and the horizontal drive assembly 44 drives the clamping mechanism 41 to sleeve the circlip 6 in the groove of the shaft 71 of the workpiece 7. The actuator 42 of the clamping assembly 46 then continues to act such that the slide block 411 continues to be depressed and the distance between the clamping arm 412 and the clamping block 43 continues to decrease, permanently deforming the split ring 6, thereby completing the assembly of the first split ring 6.

The above steps are repeated to complete the assembly of the second split ring 6. The second split ring 6 is assembled with its target surface opposite to the target surface of the first split ring 6.

During the assembly process, the clamping force and displacement of each split retainer ring 6 are respectively collected through a pressure sensor 419 and a displacement sensor 418, and compared with experience values to verify the assembly effect and control the assembly quality.

According to the split ring assembly equipment, automatic feeding, conveying and assembly of the split ring 6 can be realized, when the identification device 2 identifies that the identification surface of the split ring 6 is different from the target surface through the first material cutting component 31 and the identification device 2 which are in linkage, the split ring 6 is rotated to the target surface by controlling the rotating clamping jaw 311, so that the split rings 6 with different front and back surfaces can be assembled on the same shaft 71, and when the first split ring 6 is assembled, the second split ring 6 is fed completely, and the second assembly can be performed immediately, so that the assembly efficiency and accuracy are greatly improved; the mounting device 4 can realize rapid switching when the mounting heights are different. The design of the clamping parts can enable the split ring 6 to be assembled and deformed after being moved in place, the force and displacement of the clamping and assembling process are controllable, the split ring 6 is controllable in deformation, and the assembling quality is stable. Compared with the existing direct push-in type assembly, the split retainer ring assembly equipment disclosed by the invention is wider in application range and better in assembly effect.
