[0021] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0022] like Figures 1 to 6 The automatic snap ring installation device shown includes a frame 1, on which a positioning base 2, a lifting frame 3, and a third cylinder 4 for driving the lifting frame 3 to move up and down are respectively provided. The lifting frame 3 is located above the positioning base 2. A through hole 5 is provided through the lifting frame 3. A positioning block 6 is provided in the through hole 5, which can cause the snap ring to be snapped onto it. The lifting frame 3 is provided with a pressing mechanism 7 that can drive the snap ring on the positioning block 6 to move downward and convey it, and a feeding mechanism 8 that can drive the snap ring to be conveyed one by one and placed on the positioning block 6.

[0023] The positioning base 2 has a positioning groove, in which a fan oscillation assembly 99 is positioned and placed. The fan oscillation assembly 99 has a central shaft 100 for installing a retaining spring, and the upper end of the central shaft has a recessed groove.

[0024] Specifically, the coordinated design of the positioning block and the pressing mechanism involves a snap ring being placed on the positioning block, and then a third cylinder driving the lifting frame downwards so that the positioning block moves closer to the workpiece on the positioning base. The pressing mechanism then drives the snap ring on the positioning block downwards to be sleeved and installed on the workpiece on the positioning base, thus achieving automatic snap ring installation. Furthermore, the feeding mechanism automatically delivers the snap rings one by one to the positioning block, avoiding the drawbacks of manual placement and addition, and effectively increasing production and installation efficiency.

[0025] Furthermore, the pressing mechanism 7 includes a first cylinder 71 and a pressing sleeve 72. The lifting frame 3 is provided with a mounting bracket 73. The first cylinder 71 is mounted on the mounting bracket 73, and the pressing sleeve 72 is mounted on the drive shaft of the first cylinder 71. The pressing sleeve 72 and the through hole 5 are arranged coaxially. The pressing sleeve 72 can be moved and placed on the positioning block 6 by the first cylinder 71, and can press against the retaining spring located on the positioning block 6. Furthermore, a first notch 74 is provided on one side of the pressing sleeve 72. Specifically, the pressing mechanism drives the pressing sleeve with the first notch downwards via the first cylinder, so that the pressing sleeve moves downwards to cover the positioning block, while the end of the pressing sleeve presses against the retaining spring on the positioning block, causing the retaining spring to move vertically downwards along the axial direction of the positioning block.

[0026] Furthermore, the feeding mechanism 8 includes a feeding rod 75, a push plate 76, and a second cylinder 77 respectively disposed on the lifting frame 3. The lifting frame 3 is provided with a guide groove 78 communicating with the through hole 5. The opening of the guide groove 78 faces the feeding rod 75. The feeding rod 75 includes a first arc-shaped portion 79 and a first positioning flange 80 vertically connected to one side of the first arc-shaped portion 79. The lower end of the first positioning flange 80 is connected to the lifting frame 3. A gap 81 is left between the lower end of the first arc-shaped portion 79 and the lifting frame 3 to accommodate a retaining spring. One end of the first positioning flange 80 extends into the gap 81 with a second positioning flange 82. The push plate 76 is the drive shaft of the second cylinder 77. One end of the push plate 76 has a second notch 83 passing through the first positioning flange 80. The push plate 76 can be moved within the gap 81 by the first cylinder 71. Specifically, the feeding mechanism uses a feeding rod to stack the snap rings one by one onto the feeding rod. The first positioning flange is located in the opening gap of the snap rings to position and drop the stacked snap rings. Then, by cooperating with the push plate and the second cylinder, only one snap ring is pushed into the guide groove at a time. The snap rings fall into the positioning block in the through hole through the guide groove, realizing the automatic delivery of snap rings one by one.

[0027] Furthermore, a cover plate 84 is detachably connected to the lifting frame 3, and a guide groove 78 is formed between the cover plate 84 and the lifting frame 3. A through hole is formed on the cover plate 84 corresponding to the through hole 5. Thus, the lifting frame and the detachable cover plate form a guide groove channel for easy maintenance.

[0028] Furthermore, the positioning block 6 includes a second arc-shaped portion 61 and a third positioning flange 62 vertically connected to one side of the second arc-shaped portion 61. The third positioning flange 62 is connected to the lifting frame 3. The second arc-shaped portion 61 has an inlet section 63 and a locking section 64 from top to bottom. The diameter of the inlet section 63 gradually increases from top to bottom. The diameter of the locking section 64 is equal to the diameter of the lower end of the inlet section 63, and the diameter of the locking section 64 is larger than the inner diameter of the retaining spring and smaller than the inner diameter of the pressure sleeve 72. Specifically, the retaining spring is precisely fitted by the gradually increasing diameter of the inlet section, and the diameter of the locking section is slightly larger than the inner diameter of the retaining spring, achieving self-locking fixation through elastic deformation.

[0029] Furthermore, the lower end of the positioning block 6 is provided with a positioning post 65 coaxially. Specifically, the positioning post cooperates with the groove of the workpiece center axis 100 in the positioning base to ensure that the snap ring is accurately aligned and installed on the installation position of the center axis 100.
