Description

Technical Field

[0001] This utility model relates to the field of assembly technology of disc brake clearance adjustment mechanism, specifically to assembly tooling for disc brake adjustment mechanism. Background Technology

[0002] Disc brake adjustment mechanisms are used to adjust the brake clearance of disc brakes. Existing adjustment mechanisms are largely similar in structure, such as the one-way clearance adjustment mechanism for pneumatic disc brakes disclosed in CN114526299A and the self-adjusting clearance mechanism for vehicle disc brakes disclosed in CN105782298A. However, all of them suffer from the problem of difficulty in assembling the pressure block assembly on the main shaft. The pressure block assembly is fixed to the main shaft by an annular limiting pin, with a compression spring below it. During installation, the pressure block assembly needs to be assembled and then fitted onto the main shaft. Then, the spring is compressed downwards to expose the part of the main shaft used to install the limiting pin, and then the limiting pin is installed. Because the spring force acting on the pressure block assembly is relatively large, the assembly is quite difficult. Utility Model Content

[0003] The purpose of this utility model is to provide an assembly fixture for a disc brake adjustment mechanism to facilitate the assembly of the disc brake adjustment mechanism.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a disc brake adjustment mechanism assembly fixture, wherein the disc brake adjustment mechanism includes a main shaft and a pressure block assembly mounted on the main shaft, a compression spring is provided below the pressure block assembly, and the pressure block assembly is limited above by a limiting pin; the assembly fixture includes a base, a pressure plate arranged parallel to the base, and a driving mechanism capable of driving the pressure plate to move along the normal direction of the base, wherein the pressure plate is provided with a working hole, the diameter of which is smaller than the diameter of the pressure block assembly and larger than the outer diameter of the main shaft.

[0005] Preferably, the driving mechanism includes two cylinders, which are fixedly mounted on both ends of the base, and the output ends of the two cylinders are connected to both ends of the pressure plate.

[0006] Preferably, the bottom shape of the working hole matches the upper end face of the pressure block assembly.

[0007] Preferably, the base is provided with clearance holes at the positions of the main shaft and driven shaft of the disc brake adjustment mechanism, respectively.

[0008] Preferably, a bearing matching the spindle is provided in the clearance hole corresponding to the spindle.

[0009] Compared with the prior art, the advantages of this utility model are as follows: This utility model uses tooling to assemble the disc brake adjustment mechanism, which is simple to operate, saves time and effort, and helps to improve assembly efficiency. In the preferred embodiment of this utility model, by setting a bearing on the tooling that allows the spindle to rotate, the spindle can rotate during the assembly process, thereby facilitating the smooth alignment of the irregular hole between the spindle and the pressure block assembly.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the following embodiments will provide a more detailed description of this utility model.

[0015] Example: Assembly fixture for disc brake adjustment mechanism, refer to Figure 1-4 This fixture is mainly for assembling the compression spring and pressure block assembly on the spindle. Specifically, the disc brake adjustment mechanism 1 includes a spindle 2 and a pressure block assembly 3 mounted on the spindle. The compression spring is located below the pressure block assembly 3, and the pressure block assembly 3 is limited above by a limiting pin 4. During installation, the compression spring must first be mounted on the spindle 2, and then the pressure block assembly 3 is fitted onto the spindle 2. The inner hole of the pressure block assembly 3 and the spindle 2 are irregularly shaped holes that need to be fitted together. The pressure block assembly 3 and the spindle 2 need to be at a specific angle to be inserted. Under a certain external force, the pressure block assembly 3 compresses the spring, exposing the pin groove on the spindle. Then, the annular limiting pin 4 is installed in the pin groove to fix it, and the installation is completed.

[0016] The assembly fixture in this embodiment includes a base 5, a pressure plate 6, and two cylinders 7 capable of driving the pressure plate 6 to move along the normal direction. The two cylinders 7 are respectively fixedly disposed at both ends of the base 6, and the output ends of the two cylinders 7 are respectively connected to both ends of the pressure plate 6. When the cylinders are working, they can drive the pressure plate 6 to move up and down. The pressure plate 6 is provided with a working hole 8. The diameter of the working hole 8 is smaller than the diameter of the pressure block assembly 3 and larger than the outer diameter of the spindle 2, so that the spindle 2 can pass through the working hole 8. The lower surface of the pressure plate 6 is recessed inward at the position of the working hole 8, and its shape matches the upper end face of the pressure block assembly 3, so that the pressure block assembly 3 can be embedded in the recess, improving the stability during operation.

[0017] The base 5 is provided with a shallow groove that matches the bottom end of the disc brake adjustment mechanism for positioning. The shallow groove is provided with relief holes 9 corresponding to the positions of the main shaft and driven shaft of the disc brake adjustment mechanism, so that the main shaft 2 can rotate freely during assembly. A bearing that matches the main shaft can also be installed in the relief hole 9, so that the main shaft can pass through the inner hole of the bearing and play a certain supporting role.

[0018] During assembly, the workpiece is first placed on the base 5, with the main shaft and driven shaft corresponding to the clearance holes, and the main shaft inserted into the bearing. At this time, the upper end of the main shaft 2 corresponds exactly to the working hole 8. Then, the compression spring and the assembled pressure block assembly are installed on the main shaft in sequence. At this time, the pressure block assembly is higher than the pin groove position under the action of the compression spring. Then, the cylinder 7 starts to work, causing the pressure plate 6 to move down. During this process, the operator rotates the main shaft 2 until it corresponds to the irregular hole of the pressure block assembly 3, so that the pressure block assembly 3 can be successfully pressed into place. Then, the limit pin 4 is installed into the pin groove, and finally the cylinder is reset, thus completing the installation.

[0019] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
