[0002] The brake caliper assembly is mainly used to slow down and stop the car during driving, and generally includes a brake caliper body, a brake caliper piston, a dust cover, a sealing ring, etc.

[0003] During assembly, the existing solution generally uses pressing equipment to press the brake caliper piston and dust cover onto the brake caliper body.

[0007] Since the positioning cylinder and the cylinder hole of the brake caliper body assembled on the positioning device are coaxial, the brake caliper piston to be assembled after adjustment by the positioning device and the dust cover to be assembled which is covered on the brake caliper piston to be assembled are also coaxial with the cylinder hole. In this way, when assembling the brake caliper piston to be assembled and the dust cover to be assembled, problems such as eccentric wear and scratching can be avoided to a large extent, which is conducive to ensuring the performance of the product after assembly.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] The term “several” as used herein refers to an indefinite number of multiples, usually more than two; and when “several” is used to indicate the number of certain components, it does not indicate the quantitative relationship between these components.

[0029] The words "first", "second", etc. mentioned in this article are only for the convenience of describing two or more structures or components with the same or similar structures and / or functions, and do not imply any special limitation on the order and / or importance.

[0030] Embodiment 1

[0031] Please refer to Figure 1 , Figure 2 , Figure 1 This is a structural schematic diagram of a specific embodiment of the assembly equipment of the brake caliper piston and the dust cover provided by the present invention. Figure 2 This is a diagram of the relative positions of the positioning device and the pre-assembled accessories.

[0032] like Figure 1 , Figure 2 As shown, the present invention provides an assembly device for a brake caliper piston and a dust cover, which is used to assemble the brake caliper piston and the dust cover into a brake caliper body, including a positioning device 1, a lifting device 2 and an adjusting device 3. The positioning device 1 is used to position and install the brake caliper body A, and the brake caliper body A is provided with a cylinder hole (not shown in the figure).

[0033] Furthermore, the positioning device 3 is connected to the lifting device 2 and can be lifted and lowered under the action of the lifting device 2, and includes a positioning drive 31, a positioning cylinder 32 and a push rod 33; the positioning cylinder 32 is coaxially arranged with the cylinder hole of the brake caliper body A assembled on the positioning device 1, the brake caliper piston B1 to be assembled is sheathed on the positioning cylinder 32 through the piston hole, and the dust cover B2 to be assembled is sheathed on the brake caliper piston B1 to be assembled (the assembly of the dust cover B2 to be assembled and the brake caliper piston B1 to be assembled can be referred to as a pre-assembled accessory B); the cylinder wall of the positioning cylinder 32 is provided with a plurality of positioning portions 34 that can slide in the radial direction, and each positioning portion 34 can be arranged at intervals in the circumferential direction, preferably at equal intervals; the positioning drive 31 is transmission-connected with the push rod 33, and is used to drive the push rod 33 to displace in the positioning cylinder 32, and the push rod 33 can drive the positioning portion 34 to move radially outward to clamp the brake caliper piston B1 to be assembled, and make the brake caliper piston B1 to be assembled coaxially arranged with the positioning cylinder 32.

[0034] By adopting the above scheme, when the brake caliper piston B1 to be assembled and the dust cover B2 to be assembled are assembled, the positioning device 3 can be started, and the positioning drive member 31 can drive the push rod 33 to perform axial displacement in the positioning cylinder 32, so as to drive each positioning part 34 to move radially outward, thereby adjusting the position of the brake caliper piston B1 to be assembled, so that the brake piston B1 to be assembled and the positioning cylinder 32 can be coaxially arranged.

[0035] Since the positioning cylinder 32 is coaxial with the cylinder hole of the brake caliper body A assembled on the positioning device 1, the brake caliper piston B1 to be assembled and the dust cover B2 to be assembled which is mounted on the brake caliper piston B1 to be assembled after adjustment by the positioning device 3 are also coaxial with the cylinder hole. In this way, when the brake caliper piston B1 to be assembled and the dust cover B2 to be assembled are assembled, problems such as eccentric wear and scratching can be avoided to a large extent, which is conducive to ensuring the performance of the product after assembly.

[0036] There are two ways to install the outer sleeve of the pre-assembled accessory B on the positioning cylinder 32: 1) place the pre-assembled accessory B on the cylinder hole of the brake caliper body, start the lifting device 2 to drive the positioning device 3 to lift and lower as a whole, so that the positioning cylinder 32 can be inserted into the piston hole of the pre-assembled accessory B, and then, the positioning device 3 can be started to clamp the pre-assembled accessory B through the positioning parts 34; 2) manually insert the pre-assembled accessory B into the positioning cylinder 32 through its piston hole, and then start the positioning drive 31 so that the pre-assembled accessory B can be clamped in the positioning cylinder 32.

[0037] In combination with the above content, it can be known that the driving force required by the push rod 33 is a driving force that enables it to perform linear displacement along the axial direction of the positioning tube 32. To generate this type of driving force, the positioning drive member 31 can actually have more types of options.

[0038] For example, the positioning drive 31 can be a driving element such as a cylinder or a hydraulic cylinder that can directly generate linear displacement. In this case, the push rod 33 can be a piston rod of the cylinder or the hydraulic cylinder; or, the positioning drive 31 can also be a motor. Since the direct output of the motor is rotational displacement, a power conversion structure can also be provided between the output shaft of the motor and the push rod 33 to convert the rotational displacement output by the motor into the linear displacement required by the push rod 33. The power conversion structure can specifically be a gear rack structure, a screw structure, etc.

[0039] Please continue to refer to Figure 2 The lower end of the push rod 33 can be set as a tapered portion that tapers from top to bottom, and the inner end surface of each positioning portion 34 can have an inclined portion that gradually inclines inward from top to bottom. When the push rod 33 is displaced axially, the tapered portion can interact with the inclined portion to drive each positioning portion 34 to move radially outward, thereby completing the adjustment and positioning of the pre-assembled accessory B.

[0040] It should be noted that the above-mentioned definitions of the orientation and position relationship of "inside" and "outside" are based on the central axis of the positioning tube 32, wherein the position relatively close to the central axis is inside, and the position relatively far from the central axis is outside; the definitions of the orientation and position relationship of "upper" and "lower" in this article refer to the orientation and position relationship of the equipment during actual use, wherein the direction relatively close to the ground is lower, and the direction relatively far from the ground is upper; the inner end face of the positioning portion 34 can be set as the aforementioned inclined portion as a whole, or can be set as the aforementioned inclined portion only partially.

[0041] The hole wall of the positioning tube 32 may be provided with mounting holes, and the number of the mounting holes may be consistent with the number of the positioning portions 34 . During assembly, each positioning portion 34 may be installed in each mounting hole in a one-to-one correspondence.

[0042] Furthermore, an elastic return member 35 may be included. The elastic return member 35 may act on the positioning portion 34 . The process in which the push rod 33 drives the positioning portion 34 to move radially outward is the process in which the elastic deformation of the elastic return member 35 increases.

[0043] With this structure, when the push rod 33 is displaced along the axial direction of the positioning cylinder 32 to drive each positioning part 34 to move radially outward, the elastic potential energy of the elastic return member 35 can be increased and accumulated; when the push rod 33 is displaced in the opposite direction to release the force on the positioning part 34, the elastic potential energy accumulated by the elastic return member 35 can be released, and the positioning part 34 can be driven to automatically return to its original position so as not to affect the next assembly operation.

[0044] At the same time, the elastic return member 35 can also play a role of radial limiting, which can prevent each positioning portion 34 from being separated from the positioning tube 32 in the radial direction outward, so as to achieve outward movement limiting of each positioning portion 34.

[0045] As for the inward movement limit of the positioning portion 34 and the positioning tube 32, it can be achieved by relying on the external structure of the positioning portion 34 and the hole wall structure of the mounting hole. Figure 2 The mounting hole may include a large diameter hole section and a small diameter hole section from the outside to the inside in the radial direction of the positioning tube 32, and a first step surface may be formed between the two; the positioning portion 34 may include a large diameter section and a small diameter section from the outside to the inside, and a second step surface may be formed between the two, and the inward movement limit of the positioning portion 34 may be achieved through the abutment and cooperation between the first step surface and the second step surface.

[0046] It should be pointed out that the above-mentioned structural setting of the inward limit and outward limit of the positioning part 34 is only a preferred scheme of the embodiment of the present invention, and cannot be used as a limitation on the scope of implementation of the assembly equipment provided by the present invention. Other limiting methods can also be adopted under the condition of meeting the functions; for example, the inward limit can be achieved by conical surface cooperation, and the outward limit can be achieved by setting a blocking member such as a retaining ring on the positioning part 34.

[0047] In the original state, that is, when the push rod 33 does not interact with the positioning portion 34, the positioning portion 34 may not protrude from the outer wall of the positioning cylinder 32 to avoid affecting the smooth insertion of the positioning cylinder 32 into the piston hole of the brake caliper piston B1 to be assembled. Of course, the positioning portion 34 in the original state may also protrude from the outer wall of the positioning cylinder 32 by a certain size, as long as it does not affect the plug-in assembly of the positioning cylinder 32 and the brake caliper piston B1 to be assembled.

[0048] There are many choices for the types of the elastic return member 35, which is specifically related to its installation position. In the embodiment of the accompanying drawings, the elastic return member 35 is placed outside each positioning portion 34, and the elastic return member 35 can be an elastic ring or the like. If the elastic return member 35 is arranged inside the positioning cylinder 32, the elastic return member 35 can also be a spring.

[0049] Still Figure 1 As shown, the positioning device 3 can also include a lifting platform 36, which can include an upper platform 361 and a lower platform 362 spaced apart in the up and down directions, the positioning cylinder 32 can be installed on the lower platform 362, and the positioning drive member 31 can be installed on the upper platform 361; the lifting device 2 can interact with the lifting platform 36 to drive the positioning device 3 to move up and down.

[0050] The lifting device 2 may include a lifting drive 21 and a fixed drive platform 22, and the lifting platform 36 of the positioning device 3 may be slidably connected to the drive platform 22; specifically, one of the lifting platform 36 and the drive platform 22 may be provided with a slide rail 222a, and the other may be provided with a slider 363, and the slider 363 may be slidably matched with the slide rail 222a. The lifting drive 21 may be installed on the drive platform 22 and can act on the positioning device 3.

[0051] The structures of the lifting drive member 21 and the drive platform 22 are not limited herein, wherein: the structure of the lifting drive member 21 can be set with reference to the aforementioned positioning drive member 31; the setting of the drive platform 22 only needs to be able to achieve the above-mentioned functions. In the embodiment of the accompanying drawings, the drive platform 22 can include a bottom plate 221, a side plate 222 and a top plate 223, the side plate 222 is installed on the bottom plate 221, the top plate 223 is installed on the side plate 222, and the lifting drive member 21 can be installed on the top plate 223.

[0052] The positioning device 1 may include a positioning platform 11 and a clamping drive 12. The positioning platform 11 is used to position the brake caliper body. The specific positioning method may be pin-hole matching, etc. The clamping drive 12 may be provided with a pressure plate 121. The pressure plate 121 may be used to press the brake caliper body A against the positioning platform 11 to ensure the positioning effect of the brake caliper body A.

[0053] The clamping and releasing actions of the pressure plate 121 also require linear displacement. Therefore, the clamping drive member 12 only needs to be able to provide a driving force for linear displacement. Its specific structure can refer to the relevant limitations of the aforementioned positioning drive member 31.

[0054] After the brake caliper body A is positioned and the brake caliper piston B1 and the dust cover B2 to be assembled are aligned with the cylinder hole, the pre-assembled part B can be installed by a press-fitting process. The driving force for the press-fitting can come from the lifting device 2 or other lifting components.

[0055] Alternatively, the present invention also provides another installation method, which can be found in Figure 1 The above-mentioned assembly equipment may further include a negative pressure device 4, which may be connected to the cylinder hole. During assembly, the pre-assembled component B after centering may be placed at the cylinder hole position to block and seal the upper end of the cylinder hole, so that a relatively closed space may be formed in the cylinder hole; then, the clamping of the pre-assembled component B by the positioning device 3 may be released; then, the negative pressure device 4 may be started to generate negative pressure in the cylinder hole, thereby directly sucking the pre-assembled component B into the cylinder hole.

[0056] Compared with the traditional press-fitting process, the above-mentioned suction-fitting process is simpler and the stability of the assembly process is also higher, which has positive significance for ensuring product qualification rate and production efficiency.

[0057] Here, the embodiment of the present invention does not limit the structural form of the negative pressure device 4. During specific implementation, those skilled in the art can choose it as needed, as long as the above-mentioned technical effects can be achieved. For example, it can be a vacuum source or an exhaust component.

[0058] Embodiment 2

[0059] With respect to the assembly equipment of the brake caliper piston and the dust cover involved in each implementation manner in Example 1, the following embodiment of the present invention also provides a method for using the assembly equipment, which specifically includes the following steps:

[0060] Step S1, positioning and installing the brake caliper body A on the positioning device 1;

[0061] Step S2, putting the dust cover B2 to be assembled on the brake caliper piston B1 to be assembled to form a pre-assembled component B, and placing the pre-assembled component B at the cylinder hole of the brake caliper body A;

[0062] The above-mentioned step S1 and step S2 can be completed manually, and there is no difference in the order of the two during the implementation process.

[0063] Step S3, starting the lifting device 2 so that the positioning cylinder 32 of the positioning device 3 can be inserted into the piston hole of the brake caliper piston B1 to be assembled;

[0064] Step S4, start the positioning device 3, clamp the brake caliper piston B1 to be assembled through the positioning portion 34, so that the pre-assembled component B is coaxially arranged with the positioning cylinder 32;

[0065] Step S5, assembling the pre-assembled component B into the cylinder hole.

[0066] Since the assembly device of the brake caliper piston and the dust cover in the first embodiment has the above technical effects, the method for using the assembly device should also have similar technical effects, so it will not be described in detail here.

[0067] Combination Figure 2 The brake caliper piston B1 to be assembled is provided with a clamping portion B11, which is specifically a ring groove, and the dust cover B2 to be assembled needs to be installed on the clamping portion B11.

[0068] When the dust cover B2 to be assembled and the brake caliper piston B1 to be assembled are pre-assembled, the dust cover B2 to be assembled can be directly installed in the clamping portion B11; or Figure 2 As shown, the dust cover B2 to be assembled can also be installed on one end of the brake caliper piston B1 to be assembled, and then when the pre-assembled accessory B is installed into the cylinder hole, the dust cover B2 to be assembled is automatically clamped into the clamping part B11 by relying on the friction between the inner wall of the cylinder hole and the dust cover B2 to be assembled.

[0069] Furthermore, the above-mentioned assembly equipment may also include a negative pressure device 4, and the negative pressure device 4 is connected to the cylinder hole. Then step S5 in the above-mentioned method of use may specifically include: step S51, starting the positioning device 3 to release the clamping state of the pre-assembled component B; step S52, starting the negative pressure device 4 to suck the pre-assembled component B into the cylinder hole.

[0070] As described in part of the embodiment, in the specific implementation, in addition to the above-mentioned suction installation solution, a press installation solution can also be adopted, both of which can achieve the installation of the pre-installed accessory B.

[0071] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
