Abstract
Description
Technical Field
[0001] This invention relates to the field of welding equipment technology, and in particular to a welding positioning bracket, welding equipment and process for a rotating shaft of an automobile seat armrest. Background Technology
[0002] In the production of car seat armrests, welding the pivot and support block is a crucial step. Currently, manual welding is commonly used, but this process has significant drawbacks. During manual welding, the position of the welding equipment needs constant adjustment based on the actual welding situation to accommodate different welding angles and operational requirements. However, frequent adjustments to the welding equipment position greatly reduce welding efficiency, increase production costs per unit time, and make it difficult to meet the demands of high-efficiency operations in large-scale production.
[0003] Furthermore, the instability of the welding equipment position during manual welding leads to inconsistent welding quality between the pivot and the support block. Because it's impossible to precisely maintain the welding positions as required by the design, the welded product may exhibit problems such as pivot position deviation and uneven welds, thus affecting the normal performance of the car seat armrest, such as uneven opening and closing, wobbling, etc., and in severe cases, even posing safety hazards. At the same time, during the development phase, this welding method has poor adaptability to different design iterations; each adjustment requires a significant amount of time and manpower to readjust the welding equipment position, extending the development cycle and increasing development costs. Summary of the Invention

Detailed Implementation
[0024] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0025] Please see Figures 1 to 5 In a first aspect, the present invention provides a welding machine body for a car seat armrest pivot, comprising a processing table 1, a welding machine body 2, and an adjustment mechanism. The adjustment mechanism includes a rotating component, a transmission gear 3, an adjustment disc 4, a gear ring 5, a mounting bracket 6, and an adjustment assembly. The rotating component is installed inside the processing table 1, the transmission gear 3 is installed on the rotating component, the adjustment disc 4 is rotatably connected to the processing table 1 and located on the processing table 1, the gear ring 5 is fixedly connected to the adjustment disc 4 and meshes with the transmission gear 3, the mounting bracket 6 is fixedly connected to the adjustment disc 4 and located on the adjustment disc 4, the adjustment assembly is installed on the mounting bracket 6, and the welding machine body 2 is installed on the adjustment assembly.
[0026] In this embodiment, the processing table 1 provides the installation conditions for the adjustment mechanism. When welding the car seat armrest pivot, the car seat armrest pivot is placed on the welding bracket, and the adjustment component is activated. The adjustment component drives the welding machine body 2 to move to the welding position. The welding machine body 2 then welds the car seat armrest pivot. When the welding position of the welding machine body 2 needs to be adjusted, the rotation component is rotated. The rotation component drives the transmission gear 3 to rotate, the transmission gear 3 drives the gear ring 5 to rotate, the gear ring 5 drives the adjustment plate 4 to rotate, the adjustment plate drives the mounting bracket 6 to rotate, and the mounting bracket 6 drives the welding machine body 2 on the adjustment component to adjust the welding position. This solves the problem of frequent adjustment of the welding machine body 2 when manually welding the pivot and support block, which leads to pivot position deviation.
[0027] Furthermore, the rotating assembly includes a drive disk 7, a worm 8, and a worm wheel 9. The drive disk 7 is rotatably connected to the machining table 1 and is located on one side of the machining table 1. The worm 8 is rotatably connected to the machining table 1 and fixedly connected to the drive disk 7, and is located between the machining table 1 and the drive disk 7. The worm wheel 9 meshes with the worm 8 and is rotatably connected to the machining table 1.
[0028] In this embodiment, rotating the drive disk 7 can drive the worm 8 to rotate, the rotation of the worm 8 can drive the worm wheel 9 to rotate, and the rotation of the worm wheel 9 can drive the transmission gear 3 to rotate.
[0029] Furthermore, the adjustment mechanism also includes a limiting block 10, a return spring 11, and a moving rod 12. The limiting block 10 is slidably connected to the processing table 1 and is located on the side of the processing table 1 near the drive disk 7. The return spring 11 is fixedly connected to the limiting block 10 and to the processing table 1, and is located between the processing table 1 and the limiting block 10. The moving rod 12 is fixedly connected to the limiting block 10 and is located on one side of the limiting block 10.
[0030] In this embodiment, the drive disk 7 has multiple locking holes. The limiting block 10, in conjunction with the corresponding locking holes, can limit the drive disk 7. The rebound force of the reset spring 11 can spring the limiting block 10 into the corresponding locking hole. Pulling the moving rod 12 can pull the limiting block 10 away from the drive disk 7.
[0031] Furthermore, the adjustment assembly includes an electric actuator 13 and a fixed bracket 14. The electric actuator 13 is fixedly connected to the mounting frame 6 and located on the mounting frame 6. The fixed bracket 14 is fixedly connected to the output end of the electric actuator 13 and connected to the welding machine body 2.
[0032] In this embodiment, the operation of the electric actuator 13 can drive the welding machine body 2 on the fixed bracket 14 to adjust its position, and the fixed bracket 14 provides the installation conditions for the welding machine body 2.
[0033] Furthermore, the adjustment assembly also includes a guide slide rail 15 and a guide slider 16. The guide slide rail 15 is fixedly connected to the mounting bracket 6 and located within the mounting bracket 6. The guide slider 16 is slidably connected to the guide slide rail 15 and fixedly connected to the fixed bracket 14, and is located between the guide slide rail 15 and the fixed bracket 14.
[0034] In this embodiment, the guide rail 15 provides installation conditions for the guide slider 16. When the fixed bracket 14 moves, it drives the guide slider 16 to slide on the guide rail 15, thereby guiding and limiting the fixed bracket 14 and improving the stability of the fixed bracket 14 when it moves.
[0035] When welding the car seat armrest pivot, the car seat armrest pivot is placed on the bracket body 20. The electric actuator 13 is activated, and the electric actuator 13 drives the fixed bracket 14 to move towards the side closer to the car seat armrest pivot. After the fixed bracket 14 moves the welding machine body 2 to the welding position, the welding machine body 2 works to weld the car seat armrest pivot. When it is necessary to adjust the welding position of the welding machine body 2, the limiting block 10 is pulled away from the drive disc 7 by the moving rod 12, and the drive disc 7 is rotated. The worm gear 8 rotates, which in turn drives the worm wheel 9 to rotate. The worm wheel 9 then drives the transmission gear 3 to rotate, which in turn drives the gear ring 5 to rotate. The gear ring 5 drives the adjusting plate 4 to rotate, which in turn drives the mounting bracket 6 to rotate. The mounting bracket 6 then drives the welding machine body 2 on the fixed support 14 to adjust to the next welding position to weld the car seat armrest pivot. This solves the problem of frequent adjustments to the welding machine body 2, which leads to pivot position deviation, when manually welding pivots and support blocks.

[0037] In this embodiment, the bracket body 20 can support and position the rotating shaft of the car seat armrest.
[0038] Please see Figure 7 Thirdly, a welding process for a car seat armrest pivot, used in the welding machine body for the car seat armrest pivot described in the first aspect, includes the following steps:
[0039] S1 places the car seat armrest pivot on the welding bracket, and the adjusting component drives the welding machine body 2 to move to the welding position. The welding machine body 2 then works to weld the car seat armrest pivot.
[0040] Specifically, when welding the car seat armrest pivot, the car seat armrest pivot is placed on the bracket body 20, the electric push rod 13 is activated, the electric push rod 13 drives the fixed bracket 14 to move towards the side closer to the car seat armrest pivot, the fixed bracket 14 drives the welding machine body 2 to the welding position, and then the welding machine body 2 works to weld the car seat armrest pivot.
[0041] When it is necessary to adjust the welding position of the welding machine body 2, rotate the rotating assembly. The rotating assembly drives the transmission gear 3 to rotate, and the transmission gear 3 drives the adjusting plate 4 on the gear ring 5 to rotate. The adjusting plate drives the welding machine body 2 to adjust to the next welding position.
[0042] Specifically, when it is necessary to adjust the welding position of the welding machine body 2, the limiting block 10 is pulled away from the drive disk 7 by the moving rod 12, the drive disk 7 is rotated, the drive disk 7 drives the worm gear 8 to rotate, the worm gear 8 drives the worm wheel 9 to rotate, the worm wheel 9 drives the transmission gear 3 to rotate, the transmission gear 3 drives the gear ring 5 to rotate, the gear ring 5 drives the adjusting disk 4 to rotate, the adjusting plate drives the mounting bracket 6 to rotate, and the mounting bracket 6 drives the welding machine body 2 on the fixed bracket 14 to adjust to the next welding position to weld the car seat armrest pivot.
