Detailed Implementation
[0013] Reference Figure 1-4 As shown, the snap ring assembly machine of this utility model includes a worktable 1 and an assembly mechanism 2 mounted on the worktable 1. The assembly mechanism 2 includes a frame 3, a snap ring sleeve 4, a snap ring release sleeve 5, a first sliding seat 6 and a second sliding seat 7, a cylinder 8, and a workpiece clamp 9. The frame 3 is mounted on the worktable 1. The first sliding seat 6 is slidably mounted on the upper end of the frame 3, and the second sliding seat 7 is slidably mounted on the lower end of the frame 3. The snap ring sleeve 4 is mounted on the first sliding seat 6. The snap ring release sleeve 5 is mounted on the second sliding seat 7, and the snap ring release sleeve 5 and the snap ring sleeve 4 are concentrically arranged. The workpiece clamp 9 is located below the snap ring release sleeve 5 and is used to fix the workpiece. A linkage mechanism 10 is provided between the first sliding seat 6 and the second sliding seat 7. The cylinder 8 is mounted on the frame 3 and is used to synchronously drive the first sliding seat 6 and the second sliding seat 7 to slide up and down. The retaining spring sleeve 4 has a slot 11 at its lower end, and the lower end of the retaining spring sleeve 4 has retaining ribs 12 on both sides corresponding to the slot 11. The retaining spring release sleeve 5 has a tapered hole 13 that can bring the lower end of the retaining spring sleeve 4 toward the center. The tapered hole 13 is wider at the top and narrower at the bottom.
[0014] Preferably, the linkage mechanism 10 includes a screw 15 and a spring 16. The upper end of the screw 15 is fixedly connected to the first sliding seat 6, and the lower end of the screw 15 is movably disposed within the second sliding seat 7. The spring 16 is sleeved on the screw 15, and both ends of the spring 16 abut against the first sliding seat 6 and the second sliding seat 7, respectively. When the extension shaft of the cylinder 8 drives the first sliding seat 6 to move downward, the spring 16 applies pressure to the second sliding seat 7, which can simultaneously drive the second sliding seat 7 and the snap ring release sleeve 5 to move downward, so as to realize that the snap ring release sleeve 5 is engaged with the snap ring groove 24 at the upper end of the workpiece 23, while not affecting the continued downward movement of the first sliding seat 6 and the snap ring sleeve 4.
[0015] Preferably, the frame 3 is mounted on the lifting mechanism 17. The lifting mechanism 17 includes a lead screw seat 18, a lead screw 19 connected to the lead screw seat 18, and a crank handle 20 connected to the lead screw 19. The frame 3 is mounted on the lead screw seat 18. The starting position of the assembly mechanism 2 is adjusted by rotating the crank handle 20 to accommodate the assembly of workpieces of different specifications.
[0016] Preferably, the retaining spring sleeve 4 includes a left retaining spring sleeve 401 and a right retaining spring sleeve 402 disposed opposite to each other. The upper ends of the left retaining spring sleeve 401 and the right retaining spring sleeve 402 are fixed to the first sliding seat 6 by metal plates 21, and the slot 11 is formed between the left retaining spring sleeve 401 and the right retaining spring sleeve 402. This structure provides the retaining spring sleeve 4 with better tension, thus facilitating retraction and repositioning.
[0017] Preferably, the workpiece fixture 9 is provided with a workpiece positioning groove 22, and the workpiece 23 is placed in the workpiece positioning groove 22 for positioning, and can move left and right at the same time to realize the assembly of the two top retaining ring grooves 24.
[0018] Working principle: First, place the workpiece 23 (in this example, a cylinder) on the workpiece fixture 9. Then, insert the C-shaped snap ring into the snap ring sleeve 4's snap rib 12. Next, start the cylinder 8 to drive the snap ring sleeve 4 and the snap ring release sleeve 5 to move down synchronously. When the snap ring release sleeve 5 abuts against the workpiece 23, the snap ring sleeve 4 continues to move down and inserts into the tapered hole 13. Under the limitation of the tapered hole 1 (wider at the top and narrower at the bottom), the lower end of the snap ring sleeve 4 and the C-shaped snap ring are brought together towards the center. Then, the snap ring sleeve 4 pushes the C-shaped snap ring into the snap ring groove 24 of the workpiece 23. Finally, the machine resets.
[0019] As stated above, this is not intended to limit the present invention in any way. Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed structure and technical content to create equivalent embodiments without departing from the scope of the present invention.
