The invention relates to an automatic mounting device of a retaining ring for a hydraulic lifting valve shaft. The automatic mounting device of the retaining ring for the hydraulic lifting valve shaft according to the technical scheme of the invention is as follows: a first cavity and a second cavity, which are mutually communicated are arranged in a pressing sleeve; a pull rod can penetrate the second cavity and enter into the first cavity; a spring reset mechanism for resetting the pull rod is arranged in the first cavity; a pressing ring for pressing the retaining ring for the shaft into aretaining ring groove from the pull rod is arranged in the second cavity, and the inner diameter of the pressing ring is smaller than the outer diameter of the retaining ring for the shaft; a conicalsection is formed at the lower part of the pull rod, and the outer diameter of the lower part of the conical section is larger than the inner diameter of the retaining ring for the shaft; a pressing head sleeve is connected outside the lower part of the pressing sleeve in a sliding manner, and a guide mechanism is arranged between the pressing head sleeve and the pressing sleeve; and a driving mechanism is arranged on the pressing sleeve. The automatic mounting device has the following advantages: the automatic mounting device can quickly and automatically mount the retaining ring for the hydraulic lifting valve shaft, save labor cost, improve production efficiency and ensure safety production.
Description
Technical field [0001] The invention relates to a mounting mechanism for a retaining ring for a shaft, in particular to an automatic mounting device for a retaining ring for a hydraulic lift valve shaft. Background technique [0002] In the assembly process of the hydraulic lift valve, the installation of the shaft retaining ring is generally done manually. The worker pressed the spring seat and the spring with one hand, and the other held the retaining ring caliper for installation. If the part that the shaft is fixed with the retaining ring is composed of a spring with a relatively large elastic force, the worker does not have enough force to press the spring in place with one hand, so that the shaft retaining ring groove is exposed to install the shaft retaining ring. When this happens, two workers are required to collaborate together. One worker pressed the spring seat and spring with both hands, and the other used a retaining ring caliper to install the retaining ring for ...
