[0020] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0021] like Figures 1-3 As shown, a seat welding fixture includes a first support plate 1, a second support plate 2, and a sliding plate 5 arranged in parallel. A base plate 3 and two square tubes 10 are fixedly connected between the first support plate 1 and the second support plate 2, with the base plate 3 and the two square tubes 10 perpendicular to the first support plate 1. The base plate 3 is located at the bottom of the first support plate 1 and the second support plate 2, and the two square tubes 10 are located on the top sides of the first support plate 1 and the second support plate 2. The sliding plate 5 is located between the first support plate 1 and the second support plate 2, and is slidably connected to the base plate 3 and the two square tubes 10. A reinforcing beam 4 is fixed to the upper side of the base plate 3 to ensure the overall structural strength. The sliding plate 5 is slidably connected to the reinforcing beam 4, and both ends of the reinforcing beam 4 are fixedly connected to the first support plate 1 and the second support plate 2, respectively. The sliding plate 5 can be adjusted according to the width of the seat frame to be welded. Scale lines 18 are provided on both square tubes 10, allowing for quick adjustment to the desired position by observing the scale lines 18.

[0022] Two rotating limit pins 7 are provided on the side of the sliding plate 5 and the second support plate 2 that are close to each other. The two rotating limit pins 7 are located on both sides of the sliding plate 5 and the second support plate 2, respectively, and are used to limit the side plates on both sides of the car seat frame during welding.

[0023] A positioning mechanism is provided between the sliding plate 5 and the square tube 10. After the sliding plate 5 is adjusted, the positioning mechanism positions and fixes the sliding plate 5. The positioning mechanism includes a pressure strip 6 on the top of the sliding plate 5 and multiple ball bearing slots 16 on the top of the two square tubes 10. The multiple ball bearing slots 16 are arranged equidistantly along the axial direction of the square tubes 10. Both ends of the pressure strip 6 have cavities 13 inside. A ball bearing 12 and a spring 14 are installed inside the cavity 13. The lower end of the cavity 13 has a narrow opening. The ball bearing 12 abuts against the inner wall of the narrow opening, and the top of the ball bearing 12 abuts against the spring 14. The ball bearing 12 is adapted to the ball bearing slot 16. The lower end of the ball bearing 12 protrudes outside the bottom of the pressure strip 6, and the movement path of the ball bearing 12 when it moves with the pressure strip 6 is the distribution path of the ball bearing slots 16. When the steel ball 12 passes through the corresponding steel ball slot 16, the lower end of the steel ball 12 is pushed into the steel ball slot 16 under the pressure of the spring 14, thus playing a positioning role. Subsequently, when the sliding plate 5 is pushed, the steel ball 12 is pushed back, the spring 14 retracts, and the steel ball 12 rolls into contact with the upper surface of the square tube 10.

[0024] The pressure strip 6 has countersunk holes 11 at both ends. Screws 17 pass through the countersunk holes 11 and are inserted into the threaded holes at the top of the sliding plate 5. The pressure strip 6 and the sliding plate 5 are fixedly connected by screws 17.

[0025] Magnets 8 are provided on the side of the sliding plate 5 and the second support plate 2 that are close to each other. The magnets 8 can be attracted and fixed to the side plate of the seat frame to be welded.

[0026] A scraper 15, which is curved in an arc shape, is provided at the bottom of the sliding plate 5. A sealing strip 9 is provided at the sliding connection between the sliding plate 5 and the reinforcing beam 4, and the sealing strip 9 is fixed to the sliding plate 5. During welding, impurities and iron filings fall onto the base plate 3. The debris can be collected by pushing the sliding plate 5 towards the second support plate 2. During the pushing of the sliding plate 5, the scraper 15 is in close contact with the base plate 3 and the two are slidably connected. The debris is moved by the scraper 15. The sealing strip 9 can push the debris on the reinforcing beam 4 forward.

[0027] Working principle: The sliding plate 5 can be adjusted according to the width of the seat frame to be welded. During the adjustment process, when the steel ball 12 passes through the steel ball slot 16, the lower end of the steel ball 12 is pushed into the steel ball slot 16 under the pressure of the spring 14. The sliding plate 5 is pushed further, the steel ball 12 is pushed back, the spring 14 retracts, and the steel ball 12 rolls into contact with the upper surface of the square tube 10. When the sliding plate 5 is adjusted to the position, the steel ball 12 enters the corresponding steel ball slot 16. The elastic force of the spring makes a certain interaction force between the steel ball 12 and the steel ball slot 16. At this time, the sliding plate 5 is in a stable state.
