Description

Technical Field

[0001] This utility model belongs to the field of spot welding fixture technology, specifically a spot welding fixture for a seat back frame. Background Technology

[0002] Vehicle seats typically consist of a metal frame and a cushion made of fabric, cloth, or plastic. The frame is often manufactured using welding. Current seat frame welding processes generally involve fixing the frame with simple tooling or fixtures, followed by welding by manual labor or robotic arms.

[0003] Currently, the welding of car seat frames mainly involves the welding connection between the seat frame and the intermediate crossbeam. For the same type of seat frame, the position and structure of the crossbeam vary depending on the configuration of the vehicle. It is necessary to leave space inside the frame for the installation of devices such as heating, ventilation and massage. Therefore, for the same type of seat frame, the welding fixture needs to be adapted to the structure of different crossbeams to meet the requirements of stable relative position and facilitate accurate welding connection. At present, relevant manufacturers are still lacking in the fixtures required for this purpose. Utility Model Content

[0030] Referring to Figures 1-3, the seat back frame spot welding fixture of this embodiment includes a welding table 100, a bottom clamping assembly 200, a support assembly 300, a top clamping assembly 400, and an auxiliary assembly 500. The bottom clamping assembly 200, the support assembly 300, and the top clamping assembly 400 are all mounted on the table surface of the welding table 100. The support assembly 300 supports the seat frame 600, the bottom clamping assembly 200 and the top clamping assembly 400 clamp the seat frame 600, and the auxiliary assembly 500 supports the crossbeam 610. The crossbeam 610 and the seat frame 600 are welded together.

[0031] The auxiliary component 500 in this embodiment includes a bottom rail 510, a moving block 520, a screw 530, and an auxiliary support 540. The bottom rail 510 is bolted and installed on the table surface of the welding table 100. Multiple moving blocks 520 are installed on the bottom rail 510. The moving blocks 520 are provided with through holes. The bottom of the auxiliary support 540 is welded with a screw 530, and the screw 530 is locked in the through hole of the moving block 520 by a nut.

[0032] The bottom clamping assembly 200 of this embodiment includes an arc-shaped seat 210, a limiting block 220, a clamping cylinder 230, and a clamping plate 240. The clamping cylinder 230 and the limiting block 220 are both mounted on the arc-shaped seat 210. The arc-shaped seat 210 is bolted to the surface of the welding table 100. The tail of the seat frame 600 is clamped on the arc-shaped seat 210. The clamping cylinder 230 presses the seat frame 600 through the clamping plate 240.

[0033] The top clamping assembly 400 of this embodiment includes a top frame 410, a horizontal plate 420, a second clamping cylinder 430, and a second clamping plate 440. The top frame 410 and the second clamping cylinder 430 are mounted on the table surface of the welding table 100. The horizontal plate 420 is mounted on the top frame 410. The front end of the seat frame 600 is pressed on the horizontal plate 420. The second clamping cylinder 430 presses the seat frame 600 through the second clamping plate 440.

[0034] The support assembly 300 in this embodiment includes a support rod 310 and a support head 320. The support head 320 is mounted on the support rod 310. The bottom of the support rod 310 is threaded, and the support rod 310 is threadedly connected to the surface of the welding table 100.

[0035] In this embodiment, the horizontal plate 420 is provided with a groove, and the seat frame 600 is fitted into the groove.

[0036] Working Principle: When welding the seat frame 600 and crossbeam 610, the seat frame 600 is first placed on the support assembly 300. It is important to note that during placement, the relative height of each support rod 310 should be adjusted individually according to the structural characteristics of the seat frame 600 to ensure perfect support for the seat frame 600. Then, the bottom clamping assembly 200 and the top clamping assembly 400 clamp the top and bottom of the seat frame 600 respectively, maintaining the overall stability of the seat frame 600. The crossbeam 610 is then placed on the auxiliary support 540 of the auxiliary assembly 500, ensuring that both ends of the crossbeam 610 are aligned with the welding positions on the seat frame 600. Welding can then proceed. It should be noted that when the same seat frame 600 is suitable for different vehicle models, the crossbeam 610 is typically installed in different positions to accommodate other structures within the seat frame 600. For different welding options, the auxiliary support 540 can be moved by adjusting the moving block 520. The beam 610 is moved to different positions to form the seat back frame required for different models.

[0037] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
