The clamping plate 9 has an adjustment mechanism 10 installed on one side. By setting up the tooling base plate 1, the box body 2, the first pad 3, the limiting plate 4, the positioning component 5, the knob plunger 6, the second pad 7, the positioning column 8 and the L-shaped clamping plate 9, the relative position of the positioning component 5 and the box body 2 can be adjusted, improving the workpiece adaptability and matching with the components to be welded in different positions to adapt to the positioning of the components to be welded in different positions. This can meet the welding requirements of different positions of the product, save the device manufacturing cost, and improve the welding processing efficiency of the PACK box.

[0020] Please see Figure 1 The tooling base plate 1 is made of epoxy phenolic laminate fabric. One side of the limiting plate 4 is in contact with the box 2. The epoxy phenolic laminate fabric helps to ensure the performance stability of the tooling base plate 1 during the welding process and provides the basic conditions for the positioning function of the limiting plate 4 on the box 2, ensuring the accuracy of positioning.

[0021] Please see Figures 1-3 A measuring ruler 11 is fixedly connected to the right side of the tooling base plate 1. The surface of the measuring ruler 11 is provided with a first scale line. By setting the measuring ruler 11 and the first scale line, it is convenient to measure and position the box 2 during the welding auxiliary positioning process, which improves the positioning accuracy and operation convenience, and helps to further improve the welding quality.

[0022] Please see Figure 1 One end of the positioning component 5 passes through the limiting plate 4 and contacts the housing 2. The positioning component 5 is threadedly connected to the limiting plate 4, so that the positioning component 5 can be adjusted on the limiting plate 4, thereby more flexibly positioning the housing 2, improving the accuracy and adjustability of positioning, and adapting to different positioning requirements of the housing 2.

[0023] Please see Figure 3 The adjusting mechanism 10 includes a threaded rod 101. A groove 102 is provided on the top of the tooling base plate 1. One end of the threaded rod 101 is movably connected to the inner wall of the groove 102. A motor 103 is fixedly connected to the rear side of the tooling base plate 1. The rotating shaft of the motor 103 is fixedly connected to the threaded rod 101. A movable block 104 is threadedly fitted onto the surface of the threaded rod 101. A support rail 105 is fixedly connected to the top of the movable block 104. A slide block 106 is fitted onto the surface of the support rail 105. The surface of the slide block 106 is fixedly connected to the L-shaped clamping plate 9. By setting the threaded rod 101, groove 102, motor 103, movable block 104, support rail 105, and slide block 106, the movable block 104 can be adjusted in the threaded position. The rod 101 moves, thereby driving the support rail 105, slide 106 and L-shaped clamp 9 to move, realizing the automatic adjustment of the position of L-shaped clamp 9, improving the automation level and adjustment accuracy of positioning, reducing manual operation errors, and further improving the adaptability to different boxes 2 and the accuracy of welding positioning. By setting the groove 102, the moving block 104 is guided, which facilitates the forward and backward movement of the moving block 104. By setting the support rail 105, the slide 106 is guided, which facilitates the lateral movement of the slide 106. The position of the slide 106 on the support rail 105 can be adjusted, thereby adjusting the lateral position of the two L-shaped clamps 9, which facilitates clamping and positioning of the box 2 at different positions.

[0024] Please see Figure 3 A bolt 107 is connected through the top of the slide 106, and the bottom of the bolt 107 passes through the slide 106 and contacts the support rail 105. The bolt 107 is threadedly connected to the slide 106. The surface of the support rail 105 is provided with a second scale line. By setting the slide 106 and the bolt 107, the position of the slide 106 on the support rail 105 can be fixed, ensuring the stability of the L-shaped clamp 9 after it is adjusted to a suitable position. By setting the second scale line, it is convenient to make accurate readings when adjusting the position of the slide 106, which improves the accuracy and convenience of adjustment. At the same time, it can also measure the lateral position of the box 2, which improves the positioning accuracy of the box 2.

[0025] In use, place the box 2 on top of the tooling base plate 1, so that the front side of the box 2 contacts the limiting plate 4 and the positioning post 8. Turn the knob plunger 6 to drive the positioning part 5 to rotate. The positioning part 5 is threadedly connected to the limiting plate 4, so that the positioning part 5 abuts against the box 2. Move the slide 106 to drive the L-shaped clamp 9 to move laterally. Adjust the position between the two L-shaped clamps 9. Rotate the bolt 107 to connect with the slide 106, so that the bottom of the bolt 107 abuts against the support rail 105, locking and fixing the slide 106 and the L-shaped clamp 9. Control the motor 103 to run through the external controller to drive the threaded rod 101 to rotate. The threaded rod 101 drives the moving block 104 to move. The moving block 104 drives the support rail 105, the slide 106 and the L-shaped clamp 9 to move, so that the L-shaped clamp 9 clamps the box 2, positioning and fixing the box 2.
