Description

Technical Field

[0001] This utility model belongs to the field of welding fixture technology, and in particular relates to a welding fixture for brake components. Background Technology

[0002] A braking system generally consists of a control system, a hydraulic system, and a power assist system. It achieves braking by generating friction between the brake pads and the wheel drum or disc, converting the vehicle's kinetic energy into heat during travel. The control system is shown in the attached diagram. Figure 1 As shown, the assembly includes a support block 100, a brake switch baffle 200, a brake lever 300, a cable fixing pin 400, a brake shaft tube 500, and a brake lever bracket 600. During the production process, each component is processed independently, and then the components are welded together to form a brake assembly.

[0003] However, in current welding processes, most involve clamping and welding two components first. After welding those components, the third component is welded in sequence. This process requires repeated disassembly and reassembly for clamping and welding, which is not only cumbersome, time-consuming, and labor-intensive, but also inefficient and results in low positioning accuracy, affecting the overall welding quality. Therefore, we propose a brake component welding fixture to solve the aforementioned problems. Utility Model Content

[0009] It also includes a positioning seat, which is fixedly connected to the top of the base plate and provides positioning support for one end of the brake lever through two positioning rods.

[0010] Furthermore, each of the two card blocks has a card slot on the side where they are close to each other.

[0011] Furthermore, a baffle is fixedly connected to the top of the base plate. The height of the baffle is higher than the height of both the first support block and the second support block, and the side of the baffle closest to the positioning block abuts against the side of both the first support block and the second support block.

Detailed Implementation

[0026] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this utility model. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] Example 1: Please refer to Figures 2-5 As shown, this embodiment provides a brake assembly welding fixture, including a base plate 1, two locking blocks 2, a positioning block 3, a positioning seat 4, a first support block 6, and a second support block 7. The two locking blocks 2 are symmetrically fixed to the top of the base plate 1. Each locking block 2 has an insertion hole 21 on its side closest to each other. By inserting a rod 5 into the insertion hole 21 and the brake shaft tube 500, the locking and positioning of the brake assembly's central shaft tube and bracket portion can be completed. The positioning block 3 is fixed to the top of the base plate 1, and a positioning groove 31 is provided on the top of the positioning block 3 for locking and positioning the brake switch baffle 200. The first support block 6 and the second support block 7 are both fixedly connected to the top of the base plate 1 and arranged horizontally for supporting the support block 100 in the brake assembly. The positioning seat 4 is fixedly connected to the top of the base plate 1 and provides positioning support for one end of the brake lever 300 in the brake assembly through two positioning rods 9. The insertion rod 5 and the positioning rod 9 are both T-shaped rods.

[0028] In one aspect of this embodiment, each of the two locking blocks 2 has a locking slot 22 on its side facing each other. The locking slot 22 allows for proper placement and locking of the protruding portion of the brake shaft tube 500. After insertion, both ends of the brake shaft tube 500 abut against the inner walls of the two locking slots 22 on their opposite sides, aligning with the corresponding insertion holes 21. The insertion rod 5 is then inserted into both the insertion hole 21 and the brake shaft tube 500, thus completing the positioning of the brake shaft tube 500 and the bracket portion. Rubber rings 10 are fixedly installed in both insertion holes 21. The rubber rings 10 improve the stability of the insertion between the insertion rod 5 and the locking block 2 after insertion, thereby enhancing the stable positioning of the brake assembly and facilitating subsequent stable welding.

[0029] In one aspect of this embodiment, a positioning notch 41 is provided on one side of the top of the positioning seat 4. Two positioning holes 411, which cooperate with the positioning rods 9, are symmetrically provided on the bottom inner wall of the positioning notch 41. Two positioning rods 9 are provided. In the brake assembly, the end of the brake rod 300 away from the brake rod bracket 600 overlaps in the positioning notch 41, and the bottom wall of the positioning notch 41 has a bevel that matches the brake rod 300. Then, the positioning rods 9 are passed through the through holes on the brake rod 300 and inserted into the positioning holes 411, thereby completing the positioning connection of one end of the brake rod 300. This improves the connection and positioning of the entire brake assembly and facilitates subsequent welding.

[0030] This invention can be used in the field of brake component welding fixtures, and can also be applied to other fields.

[0031] Example 2: This example is a further improvement on the previous example: as follows Figure 2 As shown, a baffle 8 is fixedly connected to the top of the base plate 1. The height of the baffle 8 is higher than the height of both the first support block 6 and the second support block 7, and the side of the baffle 8 closest to the positioning block 3 simultaneously abuts against the side of both the first support block 6 and the second support block 7. The baffle 8 facilitates the positioning and placement of the support block 100 in the brake assembly. Furthermore, the top of the first support block 6 is horizontal, while the top of the second support block 7 is inclined to accommodate the shape of the support block 100.

[0032] Example 3: This example is a further improvement on the previous example: as follows Figure 2 , Figure 3As shown, the inner side of the locking block 2, near the first support block 6, has an integral extension 23, and the top of the extension 23 has an arc-shaped groove 231 that positions and engages with the cable fixing pin 400 in the brake assembly. After the brake lever bracket 600 in the brake assembly is positioned, the pin hole on the brake lever bracket 600 corresponds exactly to the arc-shaped groove 231. Then, the cable fixing pin 400 is inserted into the pin hole, with one end extending into the arc-shaped groove 231 for contact positioning, thereby completing the positioning between the cable fixing pin 400 and the brake lever bracket 600.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
