DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model are described clearly and completely below. The embodiments of the utility model and all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: an automatic snap ring machine for assembling snap rings includes a clamping assembly 4 and an installer 5, a top plate 3 is arranged on the top of the clamping assembly 4, a side plate 2 is fixedly connected to the bottom of the top plate 3, a bottom plate 1 is fixedly connected to the bottom of the side plate 2, a mounting assembly 6 is arranged on the front side wall of the side plate 2, a positioning block 7 is fixedly connected to the top of the bottom plate 1, and an installer 5 is arranged above the positioning block 7.

[0022] The clamping assembly 4 includes a first hydraulic rod 401, a mounting plate 402, a second hydraulic rod 403, a driving rod 404 and a clamping rod 405. The first hydraulic rod 401 is fixedly connected to the top of the top plate 3. The output end of the first hydraulic rod 401 extends through the top plate 3 to the bottom of the top plate 3 to drive the overall height change of the clamping assembly 4. The output end of the first hydraulic rod 401 is fixedly connected to the mounting plate 402. The top of the mounting plate 402 is fixedly connected to the second hydraulic rod 403. The second hydraulic rod 403 is located in front of the first hydraulic rod 401 to drive the clamping assembly 4. The closing of the clamping rod 405 improves the clamping of the installer 5. The output end of the second hydraulic rod 403 extends through the mounting plate 402 to the bottom of the mounting plate 402. The driving rod 404 is rotatably connected to the circumferential surface of the output end of the second hydraulic rod 403. The end of the driving rod 404 away from the second hydraulic rod 403 is rotatably connected to the clamping rod 405. The number of the driving rod 404 and the clamping rod 405 is set to four, and they are arranged in a circular array on the circumferential surface of the output end of the second hydraulic rod 403. The top end of the clamping rod 405 is rotatably connected to the mounting plate 402.

[0023] The installer 5 includes a clamping column 501, a mounting column 502 and a gap groove 503. The clamping column 501 is convenient for clamping by the clamping rod 405. The bottom of the clamping column 501 is fixedly connected with the mounting column 502. The mounting column 502 is a truncated cone with a larger top and a smaller bottom, and the mounting column 502 is made of elastic material. When the mounting column 502 is in a normal state, the retaining ring is sleeved on the mounting column 502 and cannot fall down. The gap groove 503 is arranged on the circumferential surface of the mounting column 502. There are multiple gap grooves 503, which are arranged in a circular array on the circumferential surface of the mounting column 502, so that the mounting column 502 is forced to close inward and undergo elastic deformation, which is convenient for the retaining ring to pass through.

[0024] The mounting assembly 6 includes a fixing plate 601, a third hydraulic rod 602 and a clamping plate 603. The fixing plate 601 is fixedly connected to the front side wall of the side plate 2 to provide an installation position for the third hydraulic rod 602 and the clamping plate 603. The front side wall of the fixing plate 601 is fixedly connected to the third hydraulic rod 602, and the output end of the third hydraulic rod 602 is fixedly connected to the clamping plate 603. There are two third hydraulic rods 602 and two clamping plates 603, which are symmetrically arranged on the front side wall of the fixing plate 601. The clamping plate 603 is driven close by the third hydraulic rod 602 to prevent the retaining ring from rising, so that it is pushed onto the product to be installed to achieve the installation of the retaining ring.

[0025] During actual use, the installer 5 is sleeved on the positioning block 7, and the retaining ring is slid into the mounting column 502 through the clamping column 501. The first hydraulic rod 401 drives the mounting plate 402 to move downward to the position of the installer 5. The second hydraulic rod 403 drives the clamping rod 405 to retract inward to clamp the clamping column 501. At the same time, the first hydraulic rod 401 drives the mounting plate 402 to rise and sleeve the product to be installed on the positioning block 7. The first hydraulic rod 401 drives the mounting plate 402 to descend, and the clamping plate 603 is driven by the third hydraulic rod 602 to close above the retaining ring. At this time, the first hydraulic rod 401 drives the mounting plate 402 to move upward, driving the clamping plate 603 to push the retaining ring downward onto the product to be installed, thereby realizing the installation of the retaining ring.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
