If the specific posture changes, the directional indications will also change accordingly.

[0034] In the description of the embodiments, unless otherwise clearly defined and limited, terms such as "arranged", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection; it can be directly connected, or connected through an intermediate medium, and can also be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0035] Refer to the attached Figure 1, which shows a component on an automotive brake caliper. The component includes a housing 1, a cylinder liner 2 is installed at one end of the housing 1, a dust cover 3 is assembled on the cylinder liner 2, and a connection plate 4 is provided at the other end of the housing 1.

[0036] See the appendix Figures 2 - 9 , which shows an automatic assembly mechanism for the dust cover, including a grasping unit 5, a lifting unit 6, and a clamping unit 7. At the same time, the grasping unit 5, the lifting unit 6, and the clamping unit 7 are all installed on the frame, and the three cooperate with each other to complete the assembly of the dust cover 3;

[0037] Among them, the grasping unit 5 includes a fixing plate 8 connected to the frame. A grasping driving cylinder 9 is installed on the fixing plate 8. An outer support claw 10 with an outward expansion action is provided at the output end of the grasping driving cylinder 9. During use, the outer support claw 10 is controlled by the grasping driving cylinder 9 to expand the dust cover 3 outward and wait for the lifting unit 6 to pick it up;

[0038] The lifting unit 6 is arranged below the output end of the grasping driving cylinder 9. The lifting unit 6 includes a mounting frame 11. A sliding driving cylinder 12 is provided on one side of the mounting frame 11. The sliding driving cylinder 12 is specifically a rodless cylinder. The output end of the sliding driving cylinder 12 is provided with a sliding plate 14 on the other side of the mounting frame 11. A first slide rail 13 is provided between the sliding plate 14 and the mounting frame 11. The first slide rail 13 is fixed on the mounting frame 11. A lifting driving cylinder 15 is provided on the sliding plate 14 in the direction towards the grasping driving cylinder 9. A top rod 16 is provided at the output end of the lifting driving cylinder 15. An assembly tooling 17 is sleeved on the top rod 16. At the same time, the joint between the top rod 16 and the assembly tooling 17 is connected by a pin 18;

[0039] The assembly tooling 17 includes a cylinder body 25. A top column 26 is provided in the cylinder body 25. A lifting plate is provided at one end of the top column 26 close to the outer support claw 10. Lifting claws 27 are provided circumferentially on the lifting plate. The lifting plate and the virtual circle where the outer support claws 10 are located are concentric. At the same time, a lifting groove 29 is provided between the lifting claws 27 and the cylinder body 25. The lifting groove 29 is used to lift the dust cover 3 as a whole. In addition, an elastic member 28 is provided on the top column 26. The elastic member 28 is specifically a compression spring. Through the elastic member 28, the entire lifting claws 27 are made elastic. During use, after the dust cover 3 is expanded outward by the outer support claws 10, the assembly tooling 17 is driven upward by the lifting driving cylinder 15, so that the lifting claws 27 are inserted into the inner hole of the dust cover 3. Then the outer support claws 10 contract inward to transfer the dust cover 3 to the lifting claws 27. Then, the entire sliding plate 14 is controlled by the sliding driving cylinder 12 to transfer the assembly tooling 17 with the dust cover 3 sleeved on it to the clamping unit 7;

[0040] The clamping unit 7 includes a fixed seat 19 connected to the frame. A clamping driving cylinder 20 is installed on the fixed seat 19. On the other side of the fixed seat 19, a second slide rail 23 is vertically provided. A support platform 21 is slidably arranged on the second slide rail 23. One end of the support platform 21 is connected to the output end of the clamping driving cylinder 20. At the same time, an avoidance opening 30 capable of accommodating the assembly tooling 17 is formed on the support platform 21. Four support columns 22 are vertically arranged around the avoidance opening 30 of the support platform 21. During use, the housing 1 is placed in the fixed seat 19 and the four support columns 22 respectively support the bottom of the housing 1. At the same time, a limiting plate 24 is provided at the top of the fixed seat 19. During use, the clamping driving cylinder 20 drives the housing 1 to move upward through the support platform 21. When the connection disk 4 on the housing 1 abuts against the limiting plate 24, the clamping of the housing 1 is realized. At the same time, the assembly tooling 17 is moved into the avoidance opening 30 by the sliding driving cylinder 12. At this time, the dust cover 3 is located directly below the cylinder sleeve 2;

[0041] During assembly, refer to the appendix Figures 10 - 11 As shown, first place the dust cover 3 on the outer support claws 10 and use the grasping driving cylinder 9 to expand the dust cover 3 outward. Then the lifting driving cylinder 15 drives the assembly tooling 17 to move upward and makes the lifting claws 27 fit into the inner hole of the dust cover 3. Then the outer support claws 10 contract inward to completely transfer the dust cover 3 to the lifting claws 27. At the same time, place the housing 1 equipped with the cylinder sleeve 2 on the four support columns 22 of the support platform 21. Use the clamping driving cylinder 20 to slide upward and cooperate with the limiting plate 24 to complete the clamping and fixing of the housing 1. Then start the sliding driving cylinder 12 to move the assembly tooling 17 picking up the dust cover 3 directly below the cylinder sleeve 2. Then start the lifting driving cylinder 15 to lift the assembly tooling 17 upward. During lifting, the lifting claws 27 elastically retract into the cylinder block 25 under the reverse action of the cylinder sleeve 2, and the dust cover 3 is sleeved on the cylinder sleeve 2 under the upward lifting action of the lifting groove 29. At this time, the entire process of assembling the dust cover 3 on the cylinder sleeve 2 is completed.

[0042] The above is only the preferred specific implementation manner of the present utility model, and does not limit the protection scope of the present utility model accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model shall be covered within the protection scope of the present utility model.
