[0028] Reference Figures 1 to 4 This utility model provides a front axle riveting fixture, including two first support parts 100 and two second support parts 200. The two first support parts 100 are spaced apart in the left-right direction, with a spacing greater than the length of the front axle base plate 702 and the front axle upper plate 701, allowing the front axle base plate 702 and the front axle upper plate 701 to be placed between them. First positioning pins 101 are vertically arranged on the opposing sides of the two first support parts 100, with the dimensions of the first positioning pins 101 matching the holes at both ends of the front axle base plate 702. The front axle base plate 702 is positioned by inserting the two first positioning pins 101 into the holes at both ends of the front axle base plate 702. The two second support parts 200 are rotatably disposed above the two first support parts 100. Normally, the two second support parts 200 extend horizontally towards each other, that is, the second support parts 200 extend horizontally above the first positioning pins 101. The second support 200 can be flipped upward from its horizontally extending position under the action of external force, thereby exiting the space above the first positioning pin 101. The second support 200 is vertically provided with a second positioning pin 201. The size of the second positioning pin 201 matches the holes at both ends of the front axle axle upper plate 701 in the length direction, thereby using the two second positioning pins 201 passing through the holes of the front axle axle upper plate 701 to position the front axle axle upper plate 701.

[0029] In this embodiment, the front axle riveting fixture positions the front axle base plate 702 by setting a first positioning pin 101 on the opposite side of the first support 100, and a second support 200 is rotatably set at the upper end of the first support 100. The front axle axle upper plate 701 is positioned by using the second positioning pin 201 on the second support 200. The front axle base plate 702 and the front axle axle upper plate 701 can be fixed vertically to facilitate the assembly and fixing of the front axle structure. After assembly and fixing, the front axle structure only needs to be lifted or hoisted upwards. The front axle base plate 702 and the front axle axle upper plate 701 will automatically disengage from the first positioning pin 101 and the second positioning pin 201. As the lifting or hoisting continues, the front axle base plate 702 can push the second support 200 upwards and be easily removed without worker operation. Therefore, after assembly, new components can be quickly inserted for the assembly of the next front axle structure, which can meet the requirements of operational convenience and solve the shortcomings of traditional fixtures.

[0030] In some embodiments of this utility model, a limiting platform is provided at the upper end of the first support part 100, and mounting parts are provided on both sides of the limiting platform along the front-back direction. The second support part 200 is rotatably connected between the two mounting parts that are opposite each other in the front and back, and maintains a horizontally extending posture by abutting against the limiting platform.

[0031] By adopting the structural configuration of this embodiment, the second support 200 is installed by setting a limiting platform and the second support 200 is horizontally limited, which simplifies the structural design and can effectively ensure the load-bearing strength of the second support 200, thereby ensuring that the second support 200 can stably support the front axle upper plate 701.

[0032] Combination Figure 1 As shown, the first support part 100 is provided with a pair of vertical plates 102 along the front-back direction. The two vertical plates 102 are provided with horizontal plates near the upper end. The horizontal plates form a limiting platform, and the vertical plates 102 form an installation part.

[0033] In some embodiments of this utility model, the first positioning pin 101 and the second positioning pin 201 are aligned vertically to achieve the positioning requirement when the holes of the front axle base plate 702 and the front axle upper plate 701 are aligned.

[0034] In some embodiments of this utility model, a buffer portion is provided between the bottom of the limiting platform and the second support portion 200. It is understood that since the second support portion 200 is rotatably mounted, achieving horizontal and upward rotation through rotation, this embodiment, by providing a buffer portion, can buffer the second support portion 200 when it rotates downward from its upward-rotating posture to abut against the limiting platform and maintain horizontality, thus preventing excessive noise.

[0035] The buffer can be made by placing wear-resistant rubber on the end faces where the two parts fit together.

[0036] Reference Figures 1 to 3 In some embodiments of this utility model, the front axle riveting fixture further includes two third support portions 300. The two third support portions 300 are located at the midpoint of the two first support portions 100 and are spaced apart in the front-rear direction. The spacing is matched with the width of the front axle base plate 702 and the front axle upper plate 701 to facilitate their insertion and removal. A third positioning pin 301 is detachably provided at the upper end of each of the two third support portions 300. The size of the third positioning pin 301 matches the bushing 705 of the front axle structure, thereby being used to insert into the bushing 705 to position it.

[0037] Because the front axle structure is symmetrically designed, the front axle upright plate 700 and bushing 705 need to be assembled and fixed in the middle. In this embodiment, a third support part 300 is set at the midpoint between the two first support parts 100, and a third positioning pin 301 is provided. The third positioning pin 301 can pass through the bushing 705 and the front axle upright plate 700 to position them. Combined with the positioning of the front axle base plate 702 and the front axle upper plate 701 by the first support part 100 and the second support part 200, the larger sections of the front axle structure can be positioned and fixed, facilitating assembly and reducing labor intensity. Furthermore, since the third positioning pin 301 is detachable, it can be removed after the front axle structure is assembled, allowing the entire front axle structure to be lifted or hoisted, ensuring ease of operation.

[0038] In some embodiments of this utility model, the upper end of the third support 300 is provided with positioning holes, and the third positioning pin 301 is inserted into the positioning holes of the two third support 300s. Furthermore, one end of the third positioning pin 301 is provided with a handle. During installation, the third positioning pin 301 is inserted into the two positioning holes, and after assembly, the third positioning pin 301 can be pulled out from one end using the handle, thus achieving quick assembly and disassembly.

[0039] Furthermore, the handle is larger than the positioning hole to achieve insertion limit. When the third positioning pin 301 is inserted into the positioning hole, the handle is used to abut against the third support part 300 to prevent excessive insertion.

[0040] In some embodiments of this utility model, the front axle riveting fixture further includes a positioning seat 500. Along the left-right direction, the positioning seat 500 is located between the two first support portions 100. Along the front-rear direction, the positioning seat 500 is offset from the first support portions 100, so that the front axle base plate 702 can be smoothly inserted without interference with the positioning seat 500. Along the front-rear direction, a protruding abutment portion 501 is provided on the side of the positioning seat 500 closest to the first support portion 100. The end face of the abutment portion 501 matches the set position of the front axle upright plate 700, and is used to abut against the front axle upright plate 700 to position the front axle upright plate 700.

[0041] By combining the third support part 300 in the aforementioned embodiments, the positional accuracy and consistency of the front axle upright plate 700 can be ensured.

[0042] Reference Figures 1 to 3 In some embodiments of this utility model, the front axle riveting fixture further includes a fourth support portion 400, which is located in the middle of the two first support portions 100 along the left-right direction. The fourth support portion 400 is horizontally provided with a support platform, and a fourth positioning pin 401 is vertically provided on the support platform. The size of the fourth positioning pin 401 matches the hole position on the steering link mounting plate 704 of the front axle structure, and the steering link mounting plate 704 can be fitted with the fourth positioning pin 401 to be stably placed on the support platform.

[0043] Because the fourth positioning pin 401 is set vertically, after the front axle structure is assembled and fixed, the front axle structure can be lifted or hoisted directly to achieve automatic separation, which can effectively ensure the convenience of processing.

[0044] Furthermore, the fourth support 400 can be located on the side of the second support 200, or it can be located independently.

[0045] Reference Figures 1 to 3 In some embodiments of this utility model, the front axle riveting fixture further includes a base frame 600, and a first support part 100, a third support part 300, and a fourth support part 400 are all disposed on the upper end surface of the base frame 600. A positioning groove 601 is recessed in the upper end surface of the base frame 600, and the size of the positioning groove 601 matches the limiting block 703 of the front axle structure, for positioning the limiting block 703.

[0046] It is understood that the limiting block 703 is set at the bottom of the front axle base plate 702. In this embodiment, the limiting block 703 is accommodated and positioned by setting a positioning groove 601 in the recess on the base frame 600, which is beneficial to improving assembly efficiency and simplifying structural design.

[0047] In some embodiments of this utility model, the lower end face of the second support portion 200 is inclined downward from the end towards the first support portion 100. When the second support portion 200 is flipped upward to a vertical position, the gravity on both sides of the second support portion 200 is balanced. With the structural configuration of this embodiment, when the front axle structure is lifted or hoisted upward, it can abut against the lower end face of the second support portion 200 to push the second support portion 200 to flip up quickly. When flipped to a vertical position, it can rely on its own weight to maintain relative stability, making it convenient to insert the components of the next front axle structure.

[0048] In some embodiments of this utility model, two first support portions 100 are slidably mounted on the base frame 600, and the vertical plates 102 of the two first support portions 100 are inclined at their proximal sides, so that the distance between the two vertical plates 102 decreases from top to bottom. Springs are provided at the opposing ends of the two first support portions 100 to keep them at their proximal ends of the sliding stroke when no external force is applied. During operation, the front axle base plate only needs to be pressed between the two first support portions 100, which can accommodate the assembly of front axle base plates and front axle axle upper plates of different lengths without manual adjustment.

[0049] The front axle riveting fixture of this utility model only requires placing the limiting block 703 into the two positioning slots 601, then placing the front axle base plate 702 in and positioning it with the first positioning pin 101. Gravity is sufficient to ensure precise docking. Next, the steering linkage mounting plate 704 is placed on the support platform, and then the two front axle upright plates 700 are placed on the front axle base plate 702. After that, the front axle shaft plate 701 is placed in and positioned with the second positioning pin 201. Finally, the bushing 705 is inserted into the two front axle upright plates 700 and fixed with the third positioning pin 301. After assembly and fixing, the third positioning pin 301 is removed, and the front axle structure can be lifted directly. Each component is positioned and fixed, which effectively ensures machining accuracy.

[0050] It is understood that the positioning structure of this utility model is also applicable to other stacked positioning structures.

[0051] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
