[0012] Among them: 1-base plate, 2-component positioning pin, 3-slider, 4-slider seat, 5-screw, 6-spring, 7-limiting bar. Detailed Implementation

[0013] The present invention will now be described in further detail.

[0014] This embodiment provides a welding fixture for C-shaped spring tube assemblies, such as... Figure 3 As shown, the C-shaped spring tube assembly welding fixture includes a base plate 1, component positioning pin 2, slider seat 4, slider 3, screw 5, spring 6, and limiting rod 7. The base plate 1 is a rectangular plate with positioning holes and threaded holes for installing component positioning pin 2 and slider seat 4, respectively. Component positioning pin 2 is fixed in the positioning hole of base plate 1 by interference fit. The bottom of slider seat 4 is provided with two waist-shaped grooves for installing screw 5 to fix slider seat 4 to base plate 1. After spring 6 is placed in the bottom hole of slider 3, it is placed in slider seat 4. Limiting rod 7 is inserted into the limiting hole on the side of slider 3 through the waist-shaped groove on the side of slider seat 4 and extends out from the waist-shaped groove on the other side of slider seat 4 to fix slider 3 in slider seat 4.

[0015] The base plate 1 is a rectangular plate, and the base plate 1 has positioning holes and threaded holes for installing component positioning pins 2 and slider seats 4, respectively. The component positioning pin 2 is fixed in the positioning hole of the base plate 1 by interference fit, which can ensure that the relative position of the C-shaped spring tube assembly and the head meets the requirements, and can more stably fix the C-shaped spring tube assembly and ensure that the dimensions meet the requirements after welding. The bottom of the slider seat 4 is provided with two waist-shaped grooves for installing screws 5 to fix the slider seat 4 to the base plate. The installation position can be adjusted left and right to ensure that the relative position of the C-shaped spring tube assembly and the head meets the requirements. The upper end of the slider 3 is provided with a square groove that can fit perfectly with the head to be welded, which can better ensure that the dimensions meet the requirements after welding. After the spring 6 is placed in the bottom hole of the slider 3, it is placed in the slider seat 4. The limiting rod 7 is inserted into the limiting hole on the side of the slider 3 through the waist-shaped groove on the side of the slider seat 4 and extends out from the waist-shaped groove on the other side of the slider seat 4 to fix the slider 3 in the slider seat 4, ensuring that the slider 3 can only slide up and down within a certain distance in the slider seat 4 and that the C-shaped spring tube assembly is in close contact with the head during welding.

[0016] The slider 3, under the action of the spring force, ensures that the cap and the C-shaped spring tube assembly are in close contact, providing favorable conditions for subsequent welding. The C-shaped spring tube assembly welding fixture, after adjusting the positions of the component positioning pin 2 and the slider seat 4 on the base plate 1, can ensure the relative position dimensions of the C-shaped spring tube assembly and the cap, improve the processing qualification rate and accuracy, and ensure the consistency of the product after welding.

[0017] The working principle of this utility model is as follows: See Figure 3 The present invention relates to a welding fixture for C-shaped spring tube assemblies, comprising a base plate 1, a component positioning pin 2, a slider seat 4, a slider 3, a screw 5, a spring 6, and a limiting rod 7. In actual use, such as Figure 4 As shown, Baotou Figure 2 The C-shaped spring tube assembly is placed snugly in the square groove at the upper end of slider 3. Figure 1 according to Figure 4 The position is aligned with component positioning pin 2.

[0018] At this point, under the action of spring 6, slider 3 pushes the cap head to fit tightly against the C-shaped spring tube assembly, at which point soldering can be used to weld it. Figure 4 The welding point shown is now complete; after welding, the assembly can be pushed upwards along the positioning groove of slider 3.

[0019] The welding fixture for the C-shaped spring tube assembly ensures that the relative position and dimensions of the C-shaped spring tube assembly and the cap meet the requirements, effectively preventing the cap from becoming skewed after welding, improving the processing qualification rate and accuracy, and meeting the dimensional requirements required for product installation.
