[0028] like Figure 1 and Figure 2 As shown, a welding fixture for the front axle housing of a mining truck includes a track 1. The track 1 is characterized by having a center rod fixing assembly 2, a welding clamping structure 3, an adjusting end 4, and a fixing end 5 connected to it. The track 1 is a long strip structure with a groove 11 for accommodating the center rod fixing assembly 2. The center rod fixing assembly 2 includes a center rod 21 and a fixing seat 22. The center rod 21 is rotatably mounted on the fixing seat 22, and the fixing seat 22 can slide along the groove 11 of the track 1 and be fixed in the desired position. The welding clamping structure 3 is located on both sides of the track 1 and includes multiple clamping members 31, which are connected by connecting members 3. 2 is connected to the track 1 and is used to clamp and fix the front axle housing assembly of the mining truck; the adjusting end 4 is located at one end of the track 1 and includes a knob 41 and an adjusting rod 42. The knob 41 is connected to the adjusting rod 42, and the adjusting rod 42 is connected to the center rod fixing assembly 2. By rotating the knob 41, the center rod fixing assembly 2 is driven to rotate, thereby realizing the rotation adjustment of the entire device; the fixing end 5 is located at the other end of the track 1 and includes a locking member 51 and a fixing end fixing seat 52. The locking member 51 is connected to the fixing end fixing seat 52 and is used to lock and fix the center rod fixing assembly 2 at the required angle position.

[0029] In this embodiment, the track 1 serves as the core frame of the entire welding fixture. Its design employs a long, narrow structure with a groove 11 to accommodate the center rod fixing assembly 2, achieving efficient space utilization and structural compactness. The center rod fixing assembly 2 consists of a center rod 21 and a fixing seat 22. The center rod 21 can rotate on the fixing seat 22, while the fixing seat 22 can slide within the groove 11 of the track 1 and be fixed in the desired position. This design gives the fixture the ability to flexibly adjust the welding angle and position during the welding process.

[0030] The welding clamping structure 3 is located on both sides of the track 1 and consists of multiple clamping components 31. These clamping components 31 are connected to the track 1 via connecting components 32, which can firmly clamp and fix the front axle housing assembly of the mining truck, ensuring the stability of the workpiece during welding. The adjusting end 4 and the fixed end 5 are located at the two ends of the track 1, respectively. The adjusting end 4 is connected to the center rod fixing assembly 2 via a knob 41 and an adjusting rod 42. The operator can rotate the center rod fixing assembly 2 by rotating the knob 41 to realize the rotation adjustment of the entire device to adapt to different welding angle requirements.

[0031] The fixed end 5 secures the center rod fixing assembly 2 to the required angle position via the locking member 51 and the fixed end fixing seat 52, ensuring the stability of the tooling during welding. This design allows the welding tooling to be flexibly adjusted and remain stable during operation, meeting the high precision and high efficiency requirements of welding the front axle housing of mining trucks.

[0032] like Figure 2 and Figure 3As shown, the track 1 has mounting portions 12 at both ends for mounting the adjusting end 4 and the fixed end 5, respectively. Each mounting portion 12 has mounting holes 121, through which bolts or other fasteners are passed to fix the adjusting end 4 and the fixed end 5 to both ends of the track 1. The center rod 21 has connecting portions 211 at both ends, which are connected to the adjusting rod 42 and the locking member 51. Each connecting portion 211 has connecting holes 2111, through which bolts or other fasteners are passed to achieve a detachable connection between the center rod 21 and the adjusting rod 42 and the locking member 51. The clamping member 31 is an adjustable jaw structure, including a jaw body 311 and an adjusting bolt 312. The jaw body 311 is connected to the connecting member 32 via the adjusting bolt 312. By rotating the adjusting bolt 312, the position and clamping force of the jaw body 311 can be adjusted to accommodate the clamping requirements of mining truck front axle housing assemblies of different sizes and shapes. The bottom of the fixing seat 22 is provided with a slider 221 that matches the slide groove 11 of the track 1. The slider 221 can slide along the slide groove 11. The connecting member 32 is a connecting rod, one end of which is connected to the clamping member 31, and the other end is fixed to the side of the track 1 by bolts or other fasteners. It is used to fix the welding clamping structure 3 to both sides of the track 1. The length and angle of the connecting member 32 can be adjusted according to actual welding requirements to optimize the clamping position and welding operation space.

[0033] In this embodiment, the connection design of the mounting part 12 of the track 1 with the adjusting end 4 and the fixed end 5 not only provides a stable mounting foundation, but also enables quick assembly and disassembly of components and positioning through the mounting holes 121, adapting to different production needs. The detachable connection of the connecting parts 211 at both ends of the center rod 21 with the adjusting rod 42 and the locking part 51 allows the center rod 21 to be quickly replaced or adjusted when needed, improving the maintenance efficiency of the tooling. The adjustable gripper structure of the clamping part 31, through the cooperation of the gripper body 311 and the adjusting bolt 312, can accurately adjust the clamping position and force, meeting the welding requirements of various mining truck front axle housing components, and avoiding the problem of clamping instability caused by changes in workpiece shape or size. The cooperation between the slider 221 at the bottom of the fixed seat 22 and the slide groove 11 of the track 1, combined with the fixing method of the locking bolt, ensures the stable sliding and precise positioning of the center rod fixing assembly 2 on the track 1, providing reliable support for angle adjustment during the welding process. The connector 32, acting as a connecting rod, allows the welding clamping structure 3 to be flexibly adjusted according to actual welding needs, optimizing the welding operation space, reducing interference between the welding torch and the tooling, and improving welding efficiency and quality.

[0034] In use, first, fix the track 1 horizontally on the workbench. Then, use bolts to install the adjusting end 4 and the fixed end 5 at both ends of the track 1 through the mounting holes 121 on the mounting part 12. Next, place the slider 221 at the bottom of the fixing seat 22 of the center rod fixing assembly 2 into the slide groove 11 of the track 1. After sliding it to the appropriate position along the slide groove 11 as needed, rotate the locking bolt 222 to fix the slider 221. Then, place the mining truck front axle housing assembly on the clamping part 31 of the welding clamping structure 3, and rotate the adjusting bolt 312. Adjust the position and clamping force of the gripper body 311 to securely hold the workpiece. Then, according to the welding requirements, rotate the knob 41 of the adjusting end 4 to drive the center rod 21 to rotate through the adjusting rod 42. After adjusting to a suitable angle, use the locking part 51 of the fixed end 5 to lock and fix the center rod 21. Finally, perform the welding operation. During the process, the length and angle of the connecting part 32 can be adjusted as needed to optimize the welding operation space and avoid interference between the tooling and the welding gun. After the welding is completed, loosen the locking bolt 222 and the locking part 51 and remove the welded workpiece.

[0035] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
