[0019] The present invention will be further described below with reference to the accompanying drawings: Example

[0020] Reference Figure 1-4 A sheet metal welding fixture includes a base 1, wherein: a limiting groove 2 and a limiting groove 3 are formed through the upper surface of the base 1 in a straight line, and the limiting groove 2 and the limiting groove 3 are not connected. A lead screw 4 is rotatably mounted in the limiting groove 2, and a lead screw 5 is rotatably mounted in the limiting groove 3. A slide block 6 is respectively driven and mounted on the lead screw 4 and the lead screw 5, and a clamping component for fixing the sheet metal part 18 is rotatably mounted on the slide block 6. The advantage of this structural design is that, through the independently set limiting groove 2 and the limiting groove 3, the rotation of the lead screw 4 and the lead screw 5 can be precisely guided respectively, avoiding mutual interference between the two, thereby ensuring the movement accuracy of the slide block 6 on the lead screw, and thus improving the positioning accuracy of the sheet metal part 18.

[0021] Specifically, a locking device is provided between the slide 6 and the clamping assembly. The locking device is used to fix the clamping assembly and the slide 6, preventing the clamping assembly from rotating. The locking device can effectively prevent the clamping assembly from rotating due to external factors during the welding process, thereby ensuring the positional stability of the sheet metal part 18 during the welding process and improving the welding quality.

[0022] Specifically, one end of lead screw 4 and lead screw 5 extends out from the corresponding limiting groove 2 and limiting groove 3 of the base 1, respectively. This design facilitates the operator's rotation of the lead screws. By manually or with the aid of tools, the movement of the slide 6 on the lead screw can be easily controlled, thereby adjusting the position of the sheet metal part 18.

[0023] Specifically, a rotating head 17 is fixedly installed at the end of lead screw 4 and lead screw 5 that rotatably extend from the base 1. The rotating head 17 further facilitates the operator in rotating the lead screw. The operator can apply a greater torque through the rotating head 17, making the lead screw rotate more easily and improving operating efficiency.

[0024] Specifically, a threaded hole 7 is provided through the side of the slide block 6, through which the slide block 6 is threadedly connected to the corresponding lead screw 4 and lead screw 5. This threaded connection has self-locking properties; when the lead screw stops rotating, the slide block 6 can stably remain in its current position and will not slip due to external forces, thus ensuring the positioning stability of the sheet metal part 18. A shaft hole 8 is provided on the upper surface of the slide block 6, in which the clamping assembly is rotatably mounted. This rotatable mounting method allows the clamping assembly to be flexibly adjusted at an angle according to the shape of the sheet metal part 18 and welding requirements. A threaded hole 9 is provided on one side of the slide block 6, in which a locking device is installed. The threaded hole 9 is connected to the shaft hole 8. This structural design facilitates the locking device to lock the clamping assembly.

[0025] Specifically, the locking device includes an adjusting bolt 10 and a pressing head 11. One end of the adjusting bolt 10 is threaded into a threaded hole 9, and the pressing head 11 is coaxially fixed to the end of the adjusting bolt 10 near the shaft hole 8. The pressing head 11 makes pressing contact with the clamping assembly. When it is necessary to lock the clamping assembly, the operator can rotate the adjusting bolt 10 to move the pressing head 11 toward the clamping assembly, thereby generating a pressing force on the clamping assembly and preventing it from rotating. When it is necessary to adjust the angle of the clamping assembly, the adjusting bolt 10 is rotated in the opposite direction to move the pressing head 11 away from the clamping assembly, thus releasing the locking state.

[0026] Specifically, the clamping assembly includes a rotating shaft 12, a geared disc 13, a U-shaped seat 14, an adjusting bolt 15, and a pressing plate 16. The geared disc 13 is coaxially fixedly mounted on the bottom of the rotating shaft 12. The geared disc 13 increases the friction and contact area between the clamping assembly and the locking device, improving the locking effect. The top of the rotating shaft 12 is fixedly connected to the bottom of the U-shaped seat 14. The design of the U-shaped seat 14 facilitates the placement and fixing of the sheet metal part 18. An adjusting bolt 15 is threadedly mounted on one side of the U-shaped seat 14. One end of the adjusting bolt 15 extends into the U-shaped cavity of the U-shaped seat 14, and the pressing plate 16 is fixedly mounted on the other end of the adjusting bolt 15. The pressing plate 16 slides within the U-shaped cavity of the U-shaped seat 14. By rotating the adjusting bolt 15, the pressing plate 16 can move within the U-shaped cavity of the U-shaped seat 14, thereby pressing and fixing the sheet metal part 18 placed in the U-shaped seat 14, adapting to sheet metal parts 18 of different sizes and shapes. The pressing head 11 and the toothed disc 13 make pressing contact to ensure that the clamping assembly will not rotate in the locked state.

[0027] In this embodiment, during use, firstly, according to the size and shape of the sheet metal part 18, place the sheet metal part 18 into the U-shaped cavity of the U-shaped seat 14. Then, rotate the adjusting bolt 15 to move the extrusion plate 16 towards the sheet metal part 18 until the sheet metal part 18 is firmly fixed in the U-shaped seat 14. Next, according to the requirements of the welding position, rotate the lead screw 4 and lead screw 5 to move the clamping assembly and the sheet metal part 18 to the appropriate position via the slide 6. After the position is adjusted, rotate the adjusting bolt 10 to move the extrusion head 11 towards the gear plate 13 to lock the clamping assembly and prevent it from rotating during welding. After completing the above operations, the welding of the sheet metal part 18 can be performed.

[0028] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
