With the continuous improvement of vehicle performance and the continuous increase in vehicle speed, people have higher and higher requirements for safety and reliability. As an important component of the automobile braking system, the assembly quality of the caliper needs to be strictly controlled. When assembling the caliper, the press-fitting part needs to be assembled in the caliper body to provide rotational support for the screw rod. In the related technology, when the press-fitting part and the caliper body are assembled, the press-fitting part is prone to tilting and instability, resulting in failure of the press-fitting part and the caliper body, resulting in a high assembly defect rate of the caliper.

It can be understood that the guide hole of the guide sleeve can guide the placement process of the press-fitting part to avoid the problem of the press-fitting part tilting when placed, and the guide hole of the guide sleeve can also guide the stamping process of the pressing block to avoid the problem of the press-fitting part tilting when the pressing block is stamped, thereby improving the assembly yield of the caliper.

[0037] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0038] Please refer to the following Figures 1 to 4 A caliper assembly tool, a caliper assembly method, and a caliper assembly device according to embodiments of the present invention are described.

[0039] like Figure 1 and Figure 3 As shown, the caliper assembly tool according to the embodiment of the present invention includes: a base 1, a connecting member 2, a guide sleeve 3 and a pressing block 4. The connecting member 2 is mounted on the base 1, and the connecting member 2 is connected to the caliper body 61 of the caliper 6. The caliper body 61 is relatively fixed to the base 1. The guide sleeve 3 is located above the base 1, and the guide sleeve 3 is mounted on the caliper body 61. The guide sleeve 3 has a guide hole 31 for assembling the press-fitting member 62. The pressing block 4 is slidably matched with the guide hole 31. The pressing block 4 can move downward under the action of an external force to press-fit the press-fitting member 62 and the caliper body 61 together.

[0040] According to the caliper assembly tool of the embodiment of the present invention, when the press-fitting piece 62 and the caliper body 61 are assembled, the caliper body 61 can be fixed by the connecting piece 2 to prevent the caliper body 61 from shaking relative to the base 1. Since the guide sleeve 3 has a guide hole 31 for assembling the press-fitting piece 62, the press-fitting piece 62 can be placed from the guide hole 31 to the press-fitting position of the caliper body 61, and the pressing block 4 can move downward under the action of an external force to press the press-fitting piece 62 and the caliper body 61 together. It can be understood that the guide hole 31 of the guide sleeve 3 can guide the placement process of the press-fitting piece 62 to avoid the problem of the press-fitting piece 62 tilting when placed, and the guide hole 31 of the guide sleeve 3 can also guide the stamping process of the pressing block 4 to avoid the problem of the press-fitting piece 62 tilting when the pressing block 4 is stamped, thereby improving the assembly yield of the caliper 6.

[0041] It should be noted that the press-fitting part 62 is a ring-sleeve structure, and the press-fitting part 62 includes a flange part 621 and a ring-sleeve part 622, and the flange part 621 is arranged at the upper end of the ring-sleeve part 622. A matching hole 613 is arranged in the caliper body 61, and when the press-fitting part 62 is press-fitted, the outer peripheral wall of the ring-sleeve part 622 and the inner peripheral wall of the matching hole 613 are interference-fitted, and the flange part 621 and the upper edge of the matching hole 613 are butted.

[0042] The guide hole 31 is coaxially arranged with the matching hole 613. Before the press-fitting part 62 is placed in the matching hole 613, the pressing block 4 needs to be removed first, so that the press-fitting part 62 is placed from the guide hole 31 to the upper end of the matching hole 613 (the press-fitting part 62 is not pressed into the matching hole 613 at this time). Then the pressing block 4 is placed into the guide hole 31. Under the action of external force, the pressing block 4 can move downward and drive the press-fitting part 62 to move downward until the annular sleeve portion 622 of the press-fitting part 62 is pressed into the matching hole 613.

[0043] In one example, the press-fitting piece 62 and the guide hole 31 are loosely matched, so that the press-fitting piece 62 can be easily passed through the guide hole 31 and the problem of tilting of the press-fitting piece 62 when placed can be avoided.

[0044] Optionally, the outer peripheral wall of the pressing block 4 and the guide hole 31 are clearance-matched. In one example, the clearance value between the outer peripheral wall of the pressing block 4 and the guide hole 31 is greater than 0 and less than or equal to 0.2 mm. For example, the clearance value between the outer peripheral wall of the pressing block 4 and the inner peripheral wall of the guide hole 31 is 0.05 mm, 0.1 mm, 0.15 mm, or 0.2 mm.

[0045] The inventor of the present application has found through experimental research that when the outer circumferential wall of the pressing block 4 and the inner circumferential wall of the guide hole 31 are larger than the above-mentioned clearance range, the coaxiality of the pressing block 4 and the guide hole 31 cannot be guaranteed, and the problem of tilting when the press-fitted part 62 is placed is easy to occur. When the outer circumferential wall of the pressing block 4 and the inner circumferential wall of the guide hole 31 are smaller than the above-mentioned clearance range, the production cost of the pressing block 4 and the guide sleeve 3 will increase, and the assembly will be inconvenient.

[0046] When the outer wall of the pressure block 4 of the caliper assembly tool of the embodiment of the present invention and the inner wall of the guide hole 31 adopt the above-mentioned gap value, the coaxiality of the pressure block 4 and the guide hole 31 can be limited to an appropriate range, thereby reducing the problem of tilting when the press-fit part 62 is pressed downward, reducing the difficulty of producing the pressure block 4 and the guide sleeve 3, and facilitating the assembly process of the pressure block 4 and the guide hole 31.

[0047] In some embodiments, the pressing block 4 has a first position before pressing and a second position after pressing. The pressing block 4 can move from the first position to the second position under the action of an external force; in the second position, the upper end of the pressing block 4 protrudes from the guide hole 31, and the lower end of the pressing block 4 abuts against the pressing piece 62. It can be understood that when the pressing block 4 is in the first position, the pressing block 4 is located in the guide hole 31 of the guide sleeve 3, the upper end of the pressing block 4 protrudes from the guide hole 31, and the height of the pressing block 4 when it is in the first position is higher than the height of the pressing block 4 when it is in the second position. Thus, the pressing block 4 is pressed by the punching device so that the pressing block 4 moves downward under the guidance of the guide hole 31. Since the pressing block 4 protrudes upward from the guide sleeve 3 in both the first position and the second position, the existence of the guide sleeve 3 will not interfere with the punching stroke of the punching device. On the other hand, since the upper end surface of the pressing block 4 is higher than the height of the guide sleeve 3 when the pressing block 4 moves downward to the extreme position (the second position), this height can be set as the target height, and the operator can determine whether the pressing piece 62 is installed in place according to this target height. In other words, when the pressure block 4 is punched downward, if the operator detects that the height is not the target height (i.e., greater than the target height or less than the target height), it means that there is a problem of poor assembly between the pressing part 62 and the caliper body 61, so that the operator can check the assembly of the caliper 6.

[0048] In one example, if Figure 3 As shown, the caliper body 61 is provided with a matching groove 614, which is arranged at the upper end of the matching hole 613 and communicated with the matching hole 613, and the matching groove 614 is coaxially arranged with the matching hole 613. The guide sleeve 3 is installed in the matching groove 614, so as to avoid the problem of radial shaking of the guide sleeve 3 relative to the matching groove 614 when the pressing block 4 is stamped.

[0049] In some embodiments, Figure 1 and Figure 3 As shown, there are multiple connecting members 2, which are arranged at intervals on the base 1, and the multiple connecting members 2 are all connected to the pliers body 61. It can be understood that the multiple connecting members 2 can fix the pliers body 61 respectively, thereby improving the stability of the pliers body 61 and the press-fitting member 62 during stamping.

[0050] In some embodiments, Figure 1 and Figure 3As shown, the connecting member 2 includes a first column 21, a sliding cavity 611 for installing a screw rod is provided on the pliers body 61, the sliding cavity 611 is coaxially arranged with the guide hole 31, the lower end of the first column 21 is connected to the base 1, and the upper end of the first column 21 is passed through the sliding cavity 611 and abuts against the pliers body 61. It can be understood that since the upper end of the first column 21 is passed through the sliding cavity 611 and abuts against the pliers body 61, the pliers body 61 can be limited by the structure of the pliers body 61 itself, and the surface of the pliers body 61 will not be damaged.

[0051] Specifically, Figure 3 As shown, the first column 21 includes a support body 211, a first flange 212 and a second flange 213. The first flange 212, the second flange 213 and the support body 211 are coaxially connected in sequence from top to bottom. In the projection plane orthogonal to the axial direction of the support body 211, the outer peripheral contour of the first flange 212 is located within the outer peripheral contour of the second flange 213. The first flange 212 and the second flange 213 are both plugged and matched with the stepped groove 612 in the sliding cavity 611. It can be understood that the first flange 212 and the second flange 213 are designed according to the structure of the sliding cavity 611 itself. Since the first flange 212 and the second flange 213 are both plugged and fixed with the stepped groove 612 in the sliding cavity 611, the caliper body 61 can be prevented from tilting, thereby improving the stability of the caliper body 61 installed on the first column 21.

[0052] Alternatively, if Figures 2 to 4 As shown, the connecting member 2 includes a second column 22, and the second column 22 includes a fixed body 221 and an abutment portion 222. The lower end of the fixed body 221 is connected to the base 1, and the upper end of the fixed body 221 is connected to the abutment portion 222. The upper side of the caliper body 61 has a pin hole 615 that penetrates in the up-down direction, and the abutment portion 222 abuts against the lower end of the pin hole 615. It can be understood that a pin shaft (not shown) needs to be punched in the pin hole 615. Since the abutment portion 222 abuts against the lower end of the pin hole 615, the caliper assembly tool of the present application can be used to punch the pin shaft. When the pin shaft is punched, the stopper effect of the abutment portion 222 can prevent the pin shaft from passing downward through the pin hole 615, thereby improving the installation accuracy of the pin shaft and the pin hole 615.

[0053] Alternatively, if Figure 1 and Figure 3As shown, the connecting member 2 includes a third column 23, and the third column 23 includes a guide body 231 and a guide portion 232. The lower end of the guide body 231 is connected to the base 1, and the upper end of the guide body 231 is fixedly connected to the guide portion 232. For example, the guide body 231 and the guide portion 232 are integrally formed, and the upper side of the caliper body 61 has an ear seat 63, and the ear seat 63 is provided with a positioning hole 631. The guide portion 232 is upwardly penetrated through the positioning hole 631, thereby further fixing the caliper body 61 and improving the stability of the installation of the caliper body 61 and the connecting column 2. It should be noted that the positioning hole 631 is a through hole and is clearance-matched with the guide portion 232, so as to facilitate the guiding and fixing of the caliper body 61, and because the guide portion 232 does not match the threaded hole of the caliper body 61, the problem of the guide portion 232 damaging the threaded surface under the action of external force when the caliper is assembled can be avoided.

[0054] In some embodiments, Figure 3 As shown, the caliper assembly tool further includes a screw member 5, and at least one of the plurality of connecting columns is detachably connected to the base 1 via the screw member 5. In a specific example, the support body 211, the fixed body 221, and the guide body 231 are all connected to the base 1 via the screw member 5, so that the first column 21, the second column 22, and the third column 23 are easily disassembled and replaced, and the assembly and processing are convenient.

[0055] A caliper assembly method according to another embodiment of the present invention adopts the caliper assembly tool according to the embodiment of the present invention, and the caliper assembly method comprises the following steps:

[0056] The clamp body 61 is mounted on the connecting member 2 to limit the movement of the clamp body 61 relative to the base 1;

[0057] Place the guide sleeve 3 in the matching groove 614 of the caliper body 61;

[0058] Place the press-fitting part 62 into the guide hole 31 of the guide sleeve 3;

[0059] Place the pressing block 4 into the guide hole 31;

[0060] A downward pressure is applied to the pressing block 4 to push the pressing piece 62 to move downward until the pressing piece 62 is pressed into the matching hole 613 of the caliper body 61 .

[0061] It is understandable that when the press-fitting part 62 and the caliper body 61 are assembled, the caliper body 61 can be fixed by the connecting part 2 to prevent the caliper body 61 from shaking relative to the base 1. Since the guide sleeve 3 has a guide hole 31 for assembling the press-fitting part 62, the press-fitting part 62 can be placed from the guide hole 31 to the press-fitting position of the caliper body 61, and the pressing block 4 can move downward under the action of the stamping device to press the press-fitting part 62 and the caliper body 61 together. It is understandable that the guide hole 31 of the guide sleeve 3 can guide the placement process of the press-fitting part 62 to avoid the problem of the press-fitting part 62 tilting when placed, and the guide hole 31 of the guide sleeve 3 can also guide the stamping process of the pressing block 4 to avoid the problem of the press-fitting part 62 tilting when the pressing block 4 is stamped, thereby improving the assembly yield of the caliper 6.

[0062] Specifically, when the caliper body 61 is installed on the connecting member 2, the upper end of the first column 21 is passed through the sliding cavity 611 and abutted against the upper end surface of the sliding cavity 611; the abutting portion 222 of the second column 22 is abutted against the lower end of the pin hole 615 on the caliper body 61; the guide portion 232 of the third column 23 is passed upward through the positioning hole 631 of the caliper 6, thereby limiting the movement of the caliper body 61 relative to the base 1.

[0063] It is understandable that, after the press-fitting part 62 is assembled, the operator can remove the guide sleeve 3 and the pressing block 4 from the caliper body 61, and then move the caliper body 61 upward to separate the caliper body 61 from the first column 21, the second column 22 and the third column 23. A caliper assembly device according to another embodiment of the present invention includes a caliper assembly tool and a punching device, wherein the caliper assembly tool is the caliper assembly tool of the embodiment of the present invention, and the punching device is disposed above the pressing block 4, and the punching device can move in the up and down direction to punch the pressing block 4.

[0064] According to the caliper assembly device of the embodiment of the present invention, when the press-fitting part 62 and the caliper body 61 are assembled, the caliper body 61 can be fixed by the connecting part 2 to prevent the caliper body 61 from shaking relative to the base 1. Since the guide sleeve 3 has a guide hole 31 for assembling the press-fitting part 62, the press-fitting part 62 can be placed from the guide hole 31 to the press-fitting position of the caliper body 61, and the pressing block 4 can move downward under the action of the stamping device to press the press-fitting part 62 and the caliper body 61 together. It can be understood that the guide hole 31 of the guide sleeve 3 can guide the placement process of the press-fitting part 62 to avoid the problem of the press-fitting part 62 tilting when placed, and the guide hole 31 of the guide sleeve 3 can also guide the stamping process of the pressing block 4 to avoid the problem of the press-fitting part 62 tilting when the pressing block 4 is stamped, thereby improving the assembly yield of the caliper 6.
