Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0035] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0036] Example: An EPB caliper piston press-fitting device, see attached document. Figure 1 -Appendix Figure 5 The device includes a pressing mechanism 2 and guide members 4. The pressing mechanism 2 is used to press the dust cover onto the outside of the piston. Multiple guide members 4 are provided, each guide member 4 corresponding to a different type of piston. The guide members 4 can press against the top of the piston to guide the dust cover to be fitted onto the piston from top to bottom. Specifically, the pressing mechanism 2 includes a connecting plate 21, connecting blocks 22, pressing jaws 23, and tension springs 24. The connecting plate 21 can move up and down. Multiple connecting blocks 22 are fixedly connected to the bottom of the connecting plate 21. The multiple connecting blocks 22 are arranged around the vertical axis of the piston. A pressing jaw 23 is hinged to the bottom of each connecting block 22. The top of the pressing jaw 23 is hinged to the connecting block 22. During rotation, the straight line along the length direction of the pressing jaw 23 is always on the same vertical plane as the vertical axis around which the multiple connecting blocks 22 are arranged. A tension spring 24 is provided between each pair of adjacent pressing jaws 23. The two ends of the tension spring 24 are fixedly connected to the two pressing jaws 23 respectively.

[0037] When pressing the dust cover onto the piston, the guide member 4 is pressed tightly against the top of the piston, and then the dust cover is fitted over the guide member 4. The connecting plate 21 then drives multiple pressing jaws 23 to move downwards. After the multiple pressing jaws 23 contact the guide member 4, the bottom of the pressing jaws 23 rotates outwards and, under the action of the tension spring 24, presses tightly against the outside of the guide member 4. The multiple pressing jaws 23 continue to move downwards until the dust cover is pressed onto the piston. The arrangement of multiple pressing jaws 23 and tension spring 24 allows the pressing mechanism 2 to adapt to the pressing operation of different piston models. When pressing the dust cover onto different piston models, only the guide member 4 corresponding to the piston model needs to be replaced.

[0038] Specifically, the guide component 4 includes a mounting part 41 and a guide part 42. The mounting part 41 is configured as a cylinder with a vertical axis, and the outer diameter of the mounting part 41 is equal to the outer diameter of the piston. A dust cover can be fitted over the mounting part 41. The guide part 42 is fixedly connected to the bottom of the mounting part 41 and is coaxially arranged with the mounting part 41. The guide part 42 is configured as a frustum, and the diameter of the top of the guide part 42 is smaller than the diameter of the mounting part 41, while the diameter of the bottom is equal to the diameter of the mounting part 41.

[0039] Specifically, the pressing mechanism 2 also includes a locking block 26, a pressure rod 25, and an elastic element 28. The locking block 26 can slide up and down with the connecting plate 21 and is located above the connecting plate 21. The pressure rod 25 is vertically arranged and passes through the locking block 26 and the connecting plate 21. One end of the pressure rod 25 extends into the space between multiple pressing jaws 23. The elastic element 28 is disposed on the locking block 26. When the pressure rod 25 moves upward relative to the locking block 26, the elastic element 28 applies a downward elastic force to the pressure rod 25. When the connecting plate 21 moves the multiple pressing jaws 23 downward and the bottom of the multiple pressing jaws 23 clamps the guide member 4, the bottom of the pressure rod 25 will contact the top of the guide member 4. Then the connecting plate 21 continues to move downward. At this time, the pressure rod 25 moves upward relative to the locking block 26 and squeezes the elastic member 28, so that the elastic member 28 applies a downward elastic force to the pressure rod 25, thereby enabling the pressure rod 25 to press the guide member 4 onto the top of the piston. During the process of pressing the dust cover onto the piston by the pressing jaws 23, the guide member 4 is pressed onto the top of the piston under the action of the pressure rod 25 and the posture of the guide member 4 does not change.

[0040] Specifically, this embodiment also includes a supporting top plate 12, a connecting plate 21 disposed below the supporting top plate 12 and movable up and down below the supporting top plate 12; two guide shafts 27 vertically passing through the supporting top plate 12 are provided on the supporting top plate 12, and the two ends of the guide shafts 27 are respectively fixedly connected to the connecting plate 21 and the locking block 26; a linear bearing is provided at the position where the guide shafts 27 pass through the supporting top plate 12, and the sliding direction of the pressure rod 25 can be guided by the setting of the guide shafts 27.

[0041] Specifically, this embodiment also includes a lifting plate 3, a clamping member, and a translating member; the lifting plate 3 can move up and down, the clamping member is used to clamp and release the guide member 4, and the translating member is used to drive the clamping member to move horizontally so that the guide member 4 can be moved to the top of the piston by the lifting of the lifting plate 3 and the horizontal movement of the clamping member.

[0042] Specifically, the clamping component includes a gripper cylinder and clamping claws 32. The gripper cylinder is connected to the translation component. Two clamping claws 32 are provided, and each clamping claw 32 is connected to one of the two fingers of the gripper cylinder. Under the action of the gripper cylinder, the two clamping claws 32 move closer and further apart, thereby clamping and releasing the guide component 4. Specifically, the sliding direction of the two clamping claws 32 is set to horizontal.

[0043] Specifically, the two clamping claws 32 are provided with vertically oriented arc-shaped grooves 321 on their sides, and the two sides of the guide member 4 can be respectively embedded into the two arc-shaped grooves 321. The two arc-shaped grooves 321 ensure that the guide member 4 remains in the same position when the two clamping claws 32 clamp it, so that the guide member 4 can be accurately placed on top of the piston.

[0044] Specifically, the translation component is configured as a translation cylinder 31, the cylinder body and piston of the translation cylinder 31 are respectively connected to the lifting plate 3 and the gripper cylinder, and the extension and retraction direction of the piston rod of the translation cylinder 31 is horizontal.

[0045] Specifically, this embodiment also includes support columns 13, of which multiple support columns 13 are provided. The lifting plate 3 is provided with linear bearings that cooperate with the support columns 13, and the linear bearings slide vertically on the support columns 13.

[0046] Specifically, two cylinders are fixedly connected to the top support plate 12. The piston rods of the two cylinders are connected to the lifting plate 3 and the connecting plate 21 respectively, so as to drive the lifting plate 3 and the connecting plate 21 to move up and down respectively.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
