[0017] Please see Figure 1 This application provides a technical solution: a circumferential automatic welding device for a gear shaft, including a base plate 19, wherein a lifting adjustment group is provided on one side of the upper surface of the base plate 19.

[0018] The lifting assembly is used to ultimately adjust the position of the working welding torch 16, thereby changing its stiffness in the vertical direction.

[0019] Specifically, the lifting adjustment assembly includes a vertical support 2 and a telescopic adjustment component 1. The telescopic end of the telescopic adjustment component 1 is connected to the mounting end of the sliding connecting seat 8, which is slidably disposed in the slide groove of the vertical support 2.

[0020] The vertical support 2 is an open-loop rectangular cuboid with a groove for engaging with the sliding connecting seat 8. Its two wings are connected to the base plate 19 by fasteners to ensure operational stability.

[0021] The telescopic adjustment component 1 is installed on the upper end of the vertical support 2 to fix it. Through its own telescopic function, it can accurately control the height position of the sliding connecting seat 8, thereby adjusting the position of the working welding torch 16 relative to the workpiece and improving the flexibility of welding.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 The movable end of the lifting adjustment group is provided with a sliding connecting seat 8, and an intermediate connecting seat 9 is movably connected to the sliding connecting seat 8. A lateral mounting bracket 11 is provided on one side of the intermediate connecting seat 9. The lateral mounting bracket 11 is connected to a welding gun holder 15 through a first right angle plate 10. A working welding gun 16 is engaged on the welding gun holder 15.

[0023] The intermediate connecting seat 9 is installed on the sliding connecting seat 8, which also facilitates the disassembly and disassembly of the intermediate connecting seat 9 and the sliding connecting seat 8, and facilitates later maintenance.

[0024] The lateral mounting bracket 11 is attached to one side of the intermediate connecting seat 9 to fix the first right angle plate 10, providing a stable support platform for the welding torch holder 15, allowing it to be finely adjusted in the horizontal direction to achieve the optimal welding angle.

[0025] More specifically, the side mounting bracket 11 is provided with an arc-shaped groove, which can further adjust the angle and position of the working welding torch 16, providing multi-dimensional position adjustment capabilities to achieve the optimal welding angle.

[0026] The first right-angle plate 10 connects the side mounting bracket 11 and the welding torch holder 15, acting as a bridge. It facilitates the installation of the welding torch holder 15 on the side mounting bracket 11, and the first right-angle plate 10 makes it easy to assemble and disassemble the welding torch holder 15, improving ease of use.

[0027] The welding torch holder 15 consists of two semi-circular locking blocks connected by fasteners to fix the working welding torch 16, thus meeting the requirements for quick replacement and stable clamping.

[0028] Please see Figure 2 The base plate 19 is also symmetrically provided with base support frames 3, and auxiliary rotating rollers 4 are sleeved between the base support frames 3. An auxiliary support frame 5 is also provided on one side of the base support frame 3, and an auxiliary adjustment component is provided on the auxiliary support frame 5.

[0029] The base plate 19 is symmetrically equipped with base supports 3 to ensure the balance and stability of the structure.

[0030] The base support 3 consists of two opposing support structures, with an auxiliary roller 4 installed between them. This provides stable support for the auxiliary roller 4.

[0031] The auxiliary roller 4 is used to support the gear shaft to be welded, so that the gear shaft can move circumferentially during the welding process, which facilitates continuous welding and improves welding efficiency and quality.

[0032] The auxiliary adjustment components ensure the precise positioning and stable rotation of the gear shaft during the welding process.

[0033] Specifically, such as Figure 1 and Figure 2 As shown, the auxiliary adjustment component includes an auxiliary retaining ring 14, which includes a lower retaining ring and an upper slide block. The upper slide block is slidably disposed in the guide groove of the horizontal section of the auxiliary support frame 5, and the lower retaining ring is disposed in the upper slide block by a locking shaft.

[0034] The auxiliary retaining ring 14 consists of a lower retaining ring and an upper sliding block. It is used to fix or adjust the position of the gear shaft to be welded on the auxiliary roller 4, ensuring that the workpiece remains stable during the welding process and can be accurately aligned with the welding torch 16.

[0035] The portion of the lower retaining ring that directly contacts the gear shaft to be welded is semi-circular to accommodate rollers of different diameters. It provides a stable clamping point, ensuring that the auxiliary roller 4 is in the working area.

[0036] The upper slide can slide within the guide groove of the horizontal section of the auxiliary support frame 5. This allows the operator to easily adjust the horizontal position of the lower retaining ring as needed to accommodate gear shafts of different lengths to be welded.

[0037] The locking shaft secures the lower retaining ring within the upper slide. The locking shaft firmly locks the lower retaining ring in place, facilitating disassembly and subsequent maintenance.

[0038] With the sliding structure of the upper slide on the auxiliary support frame 5, the auxiliary retaining ring 14 can quickly adapt to workpieces of various sizes, improving the versatility and adaptability of the equipment. At the same time, it ensures that the workpiece will not shift or shake during the welding process, which helps to improve production efficiency and product quality.

[0039] An auxiliary rotary motor 6 is provided on one side of the auxiliary support frame 5, and the output end of the auxiliary rotary motor 6 is connected to the auxiliary roller 4 located on the front side through a coupling 13.

[0040] Please see Figure 1 An auxiliary rotary motor 6 is installed on one side of the auxiliary support frame 5. It provides rotational power to make the auxiliary roller 4 rotate, thereby driving the gear shaft placed on it to rotate, thus realizing automated circumferential welding.

[0041] Place the gear shaft to be welded on the auxiliary roller 4, and turn on the auxiliary rotary motor 6 to drive the auxiliary roller 4 to rotate via the coupling 13. Adjust the motor speed according to actual needs to ensure that the workpiece rotates at an appropriate rate.

[0042] Furthermore, such as Figure 1 and Figure 2 As shown, the auxiliary adjustment component also includes a sliding adjustment shaft 7 and a baffle 12. The sliding adjustment shaft 7 is disposed in the through hole of the auxiliary support frame 5. The end of the sliding adjustment shaft 7 is provided with a baffle 12, and the outer side of the sliding adjustment shaft 7 is provided with a locking sleeve for easy positioning.

[0043] The sliding adjustment shaft 7 is installed in the through hole of the auxiliary support frame 5. Linear adjustment along a specific direction is allowed to adjust the position of the baffle 12. A locking sleeve is used to further secure the position of the sliding adjustment shaft 7. Locking or releasing the position of the sliding adjustment shaft 7 is achieved by tightening or loosening it, facilitating quick and accurate adjustment of the position of the auxiliary roller 4.

[0044] Specifically, the combination of the sliding adjustment shaft 7 and the locking sleeve provides a simple and effective method to precisely adjust the position of the baffle 12, thereby ensuring that the relative position between the workpiece and the welding torch is accurate.

[0045] The baffle 12 is used to prevent the gear shaft to be welded from slipping out, and to position the workpiece axially to ensure that no accidental movement occurs during the welding process.

[0046] Specifically, by using the baffle 12, any unnecessary movement or vibration during the welding process can be effectively avoided, thus improving the stability and reliability of the welding process.

[0047] Furthermore, such as Figure 4 As shown, a welding rod holder is provided at the lower end of the welding torch holder 15. The welding rod holder includes a retaining ring assembly, a welding rod holder 18, and a straightening holder 17. The retaining ring assembly is snapped onto the outside of the working welding torch 16. A welding rod holder 18 is provided on one side of the working welding torch 16, and a straightening holder 17 is provided on the welding rod holder 18.

[0048] The electrode holder is located at the lower end of the welding torch holder 15 to ensure that the electrode and the welding torch are always in contact during the welding process to achieve welding.

[0049] The correction holder 17 is used to correct the welding rod, ensuring that the welding rod is in the correct position and reducing welding quality problems caused by changes in the position of the welding rod.

[0050] Furthermore, the side plate on the base support 3 for attaching the auxiliary roller 4 is inclined.

[0051] In use: Place the gear shaft to be welded on the auxiliary roller 4, and use the auxiliary retaining ring 14 in the auxiliary adjustment component to initially position the gear shaft to be welded. Adjust the position of the upper slide as needed and lock it with the locking shaft so that it is within the arc-shaped sleeve of the auxiliary roller 4 and the lower retaining ring.

[0052] Adjust the position of the working welding torch 16 in the arc-shaped groove on the side mounting bracket 11 and fix it with the first right angle plate 10. According to the diameter of the gear shaft to be welded, adjust the height of the sliding connecting seat 8 with the telescopic adjustment component 1 so that the working welding torch 16 on the welding torch holder 15 reaches the appropriate starting position. Set the speed of the auxiliary rotary motor 6 according to the specific requirements of the workpiece to ensure that the workpiece can rotate at an appropriate speed for continuous welding. Place the welding rod in the welding rod holder 18 and use the straightening holder 17 to ensure that the welding rod is kept in the correct state. Turn on the auxiliary rotary motor 6 so that the auxiliary rotating roller 4 drives the gear shaft to rotate slowly and the working welding torch 16 begins welding operation.

[0053] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
