The brake caliper is an important part of a disc brake. Improper assembly of the brake caliper piston will reduce the braking effect. Seriously, it may cause traffic accidents. Therefore, studying the assembly of the brake caliper piston has great application value and practical significance.

[0003] The brake caliper is usually provided with through holes for passing bolts. In the assembly method of the caliper body and the piston, the active caliper is usually placed on the positioning posts that cooperate with the through holes, and then manual pressing and assembly are used for cooperation. However, this processing and assembly method is likely to increase the labor intensity of the staff and reduce the assembly rate of the product. Summary of the Utility Model

[0004] In order to improve the assembly efficiency of the brake caliper piston, the present application provides a brake caliper piston assembly device.

[0005] A brake caliper piston assembly device provided by the present application adopts the following technical solutions:

[0006] A brake caliper piston assembly device includes a frame and a workbench. The frame is fixedly connected to the workbench. The workbench is provided with a clamping mechanism for clamping the brake caliper. The frame is provided with a rotary pressing mechanism for installing the piston. The rotary pressing mechanism includes a pressure rod, a sleeve, and a first driving member. The sleeve is fixedly connected to the frame. A spiral groove is formed on the inner wall of the sleeve. The pressure rod is slidably connected to the sleeve along the axis of the sleeve. The pressure rod is rotatably connected to the sleeve along the axis of the sleeve. A roller is rotatably connected to the pressure rod. The roller is in rolling connection with the spiral groove. The first driving member is used to drive the sliding of the pressure rod. When the pressure rod moves to abut against the piston, the pressure rod drives the piston to move and rotate together.

[0007] By adopting the above technical solutions, the first driving member drives the pressure rod to slide. When the pressure rod slides, the roller on the pressure rod is subjected to the force in the sliding direction of the pressure rod, so that the roller rolls along the spiral groove, thereby causing the pressure rod to move and rotate at the same time. When the pressure rod abuts against the piston, the pressure rod drives the piston to move and rotate together. The piston is installed on the brake caliper through the rotational force and pressure, which improves the production efficiency, reduces the labor intensity of the operator, and better ensures the production quality of the product during the production process.

[0010] Preferably, the first driving member includes a first cylinder, the first cylinder is fixedly connected to the frame, and one end of the pressure rod is coaxially and rotatably connected to the piston rod of the first cylinder.

[0012] Preferably, a rubber part is provided at one end of the pressure rod close to the workbench. When the pressure rod moves towards the workbench side, the rubber part abuts against the piston.

[0013] By adopting the above technical solution, by making the rubber part abut against the piston, the friction force when the pressure rod contacts the piston can be increased, and the possibility of slipping between the pressure rod and the piston can be reduced; at the same time, the possibility of scratching or bruising the piston and the surface of the brake caliper by the pressure rod is reduced, so that during the production process, the production efficiency is improved, the labor intensity of the operator is reduced, and the product production quality is better guaranteed.

[0014] Preferably, the clamping mechanism includes a positioning column, a pressing plate and a second driving member. The positioning column is fixedly connected to the workbench, the pressing plate is slidably connected to the workbench in the vertical direction, and the second driving member is used to drive the sliding of the pressing plate. When the brake caliper is placed on the positioning column, the pressing plate slides to abut against the brake caliper to press the brake caliper.

[0030] The following further describes the present application in detail in conjunction with the attached Figures 1 - 5 drawings to make the technical solution of the present application easier to understand and master.

[0031] An embodiment of the present application discloses a brake caliper piston assembly device.

[0032] Referring to Figures 1 - 4, A brake caliper piston assembly device according to this embodiment includes a frame 1 and a workbench 2. The frame 1 is fixedly connected to the workbench 2. A clamping mechanism 3 for clamping the brake caliper 5 is installed on the workbench 2. A rotary pressing mechanism 4 for assembling the piston 51 is installed on the frame 1. The rotary pressing mechanism 4 includes a pressing rod 41, a sleeve 42, and a first driving member 43. The sleeve 42 is fixedly connected to the frame 1. A plurality of spiral grooves 421 are formed on the inner wall of the sleeve 42, and the plurality of spiral grooves 421 are evenly distributed along the circumferential direction of the sleeve 42. The pressing rod 41 is slidably connected to the sleeve 42 along the axial direction of the sleeve 42, and the pressing rod 41 is rotatably connected to the sleeve 42 along the axial direction of the sleeve 42. A plurality of rollers 411 are rotatably connected to the pressing rod 41. The plurality of rollers 411 respectively correspond to the plurality of spiral grooves 421, and the plurality of rollers 411 are respectively rollingly connected in the spiral grooves 421. The first driving member 43 is used to drive the sliding of the pressing rod 41. A docking block 413 is fixedly connected to one end of the pressing rod 41 close to the workbench 2. A docking groove that can cooperate with the docking block is formed on the piston 51 of the brake caliper 5. When the pressing rod 41 moves to abut against the piston 51, the docking block 413 cooperates with the docking groove, and the pressing rod 41 drives the piston 51 to move and rotate together.

[0033] Referring to Figures 1 - 4 , the first driving member 43 drives the pressing rod 41 to slide. When the pressing rod 41 slides, the rollers 411 on the pressing rod 41 are subjected to the force in the sliding direction of the pressing rod 41, causing the rollers 411 to roll along the spiral grooves 421, so that the pressing rod 41 moves and rotates at the same time. When the pressing rod 41 abuts against the piston 51, the pressing rod 41 drives the piston 51 to move and rotate together. By the rotational force and pressure, the piston 51 is installed on the brake caliper 5, which improves the production efficiency, reduces the labor intensity of the operator, and better guarantees the product production quality during the production process. The arrangement of the plurality of spiral grooves 421 and the rollers 411 reduces the possibility that the rollers 411 are stuck and unable to rotate the pressing rod 41, improves the bearing capacity of the sleeve 42 for the movement of the pressing rod 41, reduces the possibility of the pressing rod 41 deviating during the movement, facilitates the use of the pressing rod 41, and thus improves the assembly efficiency of the piston 51 of the brake caliper 5.

[0034] Referring to Figures 1 - 3 , the first driving member 43 includes a first cylinder 431. The first cylinder 431 is fixedly connected to the frame 1. One end of the pressing rod 41 is coaxially and rotatably connected to the piston rod of the first cylinder 431. Through the movement of the piston of the first cylinder 431, the pressing rod 41 is driven to perform reciprocating motion, and one end of the pressing rod 41 is rotatably connected to the piston rod of the first cylinder 431, reducing the interference during the movement of the pressing rod 41, facilitating the use of the pressing rod 41, and improving the assembly efficiency of the piston 51 of the brake caliper 5.

[0035] Referring to Figure 5, a rubber part 412 is fixedly connected to one end of the compression bar 41 close to the workbench 2. The outer surface of the docking block 413 is wrapped by the rubber part 412, and the docking groove can cooperate with the outer surface of the wrapped docking block 413; when the compression bar 41 moves towards the workbench 2, the rubber part 412 abuts against the piston 51, and the docking block 413 after wrapping the rubber part 412 cooperates with the docking groove. By making the rubber part 412 abut against the piston 51, the friction force when the compression bar 41 contacts the piston 51 can be increased, and the possibility of slipping between the compression bar 41 and the piston 51 can be reduced; at the same time, the possibility of scratching or bruising the piston 51 and the surface of the brake caliper 5 caused by the compression bar 41 can be reduced, so that during the production process, the production efficiency is improved, the labor intensity of the operator is reduced, and the product production quality is better guaranteed.

[0036] Referring to Figures 1 - 3 , the clamping mechanism 3 includes two positioning columns 31, two pressing plates 32 and a second driving member 33. The two positioning columns 31 are respectively fixedly connected to the workbench 2, the two pressing plates 32 are respectively slidably connected to the workbench 2 in the vertical direction, and the second driving member 33 is used to simultaneously drive the sliding of the two pressing plates 32. When the brake caliper 5 is placed on the two positioning columns 31, the two pressing plates 32 slide to abut against the brake caliper 5 to press the brake caliper 5. By driving the two pressing plates 32 to slide through the second driving member 33, the two pressing plates 32 slide to abut against the brake caliper 5 placed on the positioning columns 31 to press the brake caliper 5, reducing the possibility of the brake caliper 5 moving during the assembly process.

[0037] Referring to Figures 1 - 3 , first positioning blocks 311 that can cooperate with the through holes on the brake caliper 5 are coaxially and fixedly connected to the two positioning columns 31 respectively, second positioning blocks 321 that can cooperate with the through holes on the brake caliper 5 are fixedly connected to the two pressing plates 32 respectively, and the two first positioning blocks 311 are coaxial with the corresponding second positioning blocks 321 respectively; two guide columns 21 are fixedly connected to the workbench 2. The two guide columns 21 correspond to the two pressing plates 32. The two guide columns 21 respectively pass through the corresponding pressing plates 32, and the two pressing plates 32 are respectively slidably connected to the corresponding guide columns 21 along the axial direction of the corresponding guide columns 21. The arrangement of the guide columns 21 reduces the possibility of the sliding deviation of the pressing plates 32; the arrangement of the first positioning blocks 311 and the second positioning blocks 321 can enable the positioning columns 31 and the pressing plates 32 to better position the brake caliper 5, reducing the possibility of the brake caliper 5 moving; thereby positioning the assembly of the piston 51 and reducing the possibility of the piston 51 hitting the outer surface of the brake caliper 5 during the assembly process. So that during the production process, the production efficiency is improved, the labor intensity of the operator is reduced, and the product production quality is better guaranteed.

[0038] Referring to Figures 1 - 3, the second driving member 33 includes a second cylinder 331. The second cylinder 331 is fixedly connected to the workbench 2. One end of the piston rod 51 of the second cylinder 331 is fixedly connected with a connecting plate 332. Two pressing plates 32 are respectively fixedly connected to the connecting plate 332. Through the movement of the piston 51 of the piston rod 51 of the second cylinder 331, the two pressing plates 32 are driven to move reciprocally simultaneously, facilitating the movement of the pressing plates 32, and thus facilitating the pressing of the brake caliper 5.

[0039] Of course, the above are only typical examples of the present application. In addition, the present application can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
