In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0036] Reference Figures 1 to 4 As shown, the utility model is used for the installation of the retaining ring of the cylinder, and is particularly suitable for the installation of the retaining ring 8 which is difficult to install manually, saving time and reducing the labor intensity. A cylinder retaining ring quick installation mechanism is provided, comprising a cylinder fixing seat 1, a retaining ring shrinking block 2 arranged above the cylinder fixing seat 1, a retaining ring fixing block 3 arranged above the retaining ring shrinking block 2, and a pushing assembly 4 for pushing the retaining ring 8; a shrinking guide hole 21 is provided in the retaining ring shrinking block 2, which is used to force the retaining ring 8 to shrink until its outer diameter is smaller than the inner diameter of the retaining ring groove of the cylinder 9; the cylinder fixing seat 1 is used to support and fix the cylinder 9, and make the retaining ring groove of the cylinder 9 located at the bottom of the shrinking guide hole 21; the retaining ring fixing block 3 is used to position the retaining ring 8; the pushing assembly 4 is used to push the retaining ring 8 out of the retaining ring fixing block 3, and push it into the retaining ring groove of the cylinder 9 after shrinking through the shrinking guide hole 21.

[0037] A positioning structure 5 is provided between the circlip shrinking block 2 and the circlip fixing block 3, so that the circlip shrinking block 2 and the circlip fixing block 3 can be locked and positioned. The positioning structure 5 includes a plurality of positioning bosses 51 arranged at intervals on the top of the circlip shrinking block 2, and a plurality of positioning holes 52 arranged at the bottom of the circlip fixing block 3 and matching with the plurality of positioning bosses 51.

[0038] In order to accurately fix the position of the circlip retaining ring 8 after the circlip shrinking block 2 and the circlip fixing block 3 are engaged and positioned, a plurality of positioning bosses 51 are arranged along the edge of the shrinking guide hole 21, and the positioning hole 52 is opened on the inner wall of the pushing movable hole (the positioning hole 52 is connected to the pushing movable hole), so that when the positioning bosses 51 and the positioning holes 52 are engaged and positioned, the circlip fixing block 3 and the circlip shrinking block 2 are crossed and closed. Of course, the positioning bosses 51 can also be arranged at the bottom of the circlip fixing block 3, and the positioning holes 52 can be opened on the top of the circlip shrinking block 2.

[0039] It also includes a positioning drive member 6, which is used to drive the clamp spring contraction block 2 and the clamp spring fixing block 3 to be clamped and positioned through the positioning structure 5. Specifically, the positioning drive member 6 is a cylinder.

[0040] The shrink guide hole 21 is set as a round hole with a gradually converging inner diameter from top to bottom. The shrink guide hole 21 forms a V-shaped tapered hole. When the push assembly 4 pushes the retaining ring 8 through the shrink guide hole 21, the retaining ring 8 is forced to shrink its outer diameter. The same retaining ring shrink block 2 can be used as long as the inner diameter of the retaining ring groove of the cylinder 9 is larger than the minimum inner diameter of the shrink guide hole 21 after convergence. It can also be adapted to the assembly of cylinders with different cylinder diameters and different retaining ring 8 specifications by replacing different retaining ring shrink blocks 2 (different shrink guide holes 21), and has strong versatility.

[0041] The pushing assembly 4 includes a pushing block 41 and a pushing block driving member 42 for driving the pushing block 41 to push the retaining ring 8. A pushing movable hole for accommodating the retaining ring 8 and the pushing block 41 is provided in the retaining ring fixing block 3, and a plurality of magnetic suction members are inlaid at intervals on the inner wall of the bottom of the pushing movable hole; the pushing block 41 is movably arranged in the upper part of the pushing movable hole.

[0042] In this embodiment, the push block driving member 42 is a cylinder, and the magnetic attraction member is a magnet. When the push block driving member 42 drives the push block 41 to descend, the push block 41 pushes the retaining ring 8 to disengage from the adsorption of the magnetic attraction member, and gradually shrinks the outer diameter under the forced guidance of the shrinking guide hole 21.

[0043] It also includes a bracket 7; the bracket 7 includes a top plate 71 and a bottom plate 72 arranged in parallel, and a plurality of support rods 73 fixed between the top plate 71 and the bottom plate 72; the positioning drive member 6 is installed on the top plate 71, and the cylinder fixing seat 1 is installed on the bottom plate 72. A support plate 74 and a guide assembly 75 are also installed in the middle of the support rod 73; the clip spring shrink block 2 is detachably installed on the support plate 74; the clip spring fixing block 3 is installed on the guide assembly 75, and the guide assembly 75 is used to guide the clip spring fixing block 3 to rise and fall along the support rod 73 to achieve the clamping and positioning with the clip spring shrink block 2. The guide assembly 75 includes a guide plate and a plurality of guide sleeves slidably connected to the support rod 73; the clip spring fixing block 3 is installed at the bottom of the guide plate.

[0044] It also includes a height adjustment plate 76 disposed at opposite sides of the support plate 74; the middle of the height adjustment plate 76 is provided with an adjustment waist-shaped hole along its vertical direction, and the support plate 74 is fixedly mounted and fixed to the height adjustment plate 76 through the adjustment waist-shaped hole; the lower end of the height adjustment plate 76 is fixed to the bottom plate 72, and the adjustment waist-shaped hole is provided at the upper part of the height adjustment plate 76. By providing the adjustment waist-shaped hole, the installation height of the support plate 74 can be adjusted, that is, the height of the clip spring contraction block 2 can be adjusted to adapt to cylinder barrels 9 of different heights. In order to avoid damaging the cylinder barrel 9, an elastic member 77 is also sleeved on each support rod 73, and the two ends of the elastic member 77 abut between the support plate 74 and the bottom plate 72.

[0045] The working process of the utility model is as follows:

[0046] 1) Install the retaining ring 8 into the push-moving hole of the retaining ring fixing block 3. The magnetic suction piece embedded in the inner wall of the push-moving hole will adsorb and fix the retaining ring 8 on the retaining ring fixing block 3;

[0047] 2) The positioning drive member 6 drives the retaining spring fixing block 3 to be pressed downward, so that the retaining spring fixing block 3 is engaged and positioned with the positioning structure 5 of the retaining spring shrinking block 2. At this time, the pushing movable hole is connected with the shrinking guide hole 21 to ensure that the position of the retaining spring retaining ring 8 does not change;

[0048] 3) The push block driving member 42 drives the push block 41 to push the circlip retaining ring 8 to move downward, and then combines with the shrinking guide hole 21 on the circlip shrinking block 2 to force the circlip retaining ring 8 to shrink its outer diameter until it is smaller than the inner diameter of the circlip groove of the cylinder 9;

[0049] 4) The push block driving member 42 continues to operate, so that the retaining ring 8 reaches the corresponding position of the retaining ring groove of the cylinder barrel 9 and then expands and is fixed in the retaining ring groove naturally;

[0050] 5) The push block driving member 42 and the positioning driving member 6 are reset, and the action is completed.
