[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Referring to Figures 1-5 , a sheet metal spot welding support device, including two groups of symmetrically arranged bases 1. Above the base 1, there is a support plate 2. A fixed pressing plate 3 is fixedly installed at the edge of the support plate 2. A threaded shaft 4 is threadedly connected in the middle of the fixed pressing plate 3. The bottom end of the threaded shaft 4 is rotatably connected to a movable pressing plate 22. Between one group of the base 1 and a fixed frame 11, they are fixedly connected by a control telescopic rod 23. Between the other group of the base 1 and the fixed frame 11, they are fixedly connected by a fixed rod 5. A support table 9 is arranged between the two groups of bases 1. An adjustable telescopic sleeve 10 is fixedly installed at the top end of the support table 9. Since sheet metal parts with different thicknesses are placed at different heights above the support plate 2, the detection device can be made to fit the sheet metal part by adjusting the telescopic sleeve 10. A fixed frame 11 is fixedly installed at the top end of the adjustable telescopic sleeve 10. A detection head 12 is slidably connected to the bottom end of the fixed frame 11. Adjusting telescopic rods 13 are fixedly installed on both sides of the fixed frame 11. The free ends of the adjusting telescopic rods 13 are fixedly connected to the detection head 12. The detection head 12 includes a housing 14. A detection coil 15 is fixedly installed inside the housing 14. A connecting rod 16 is slidably connected in the middle of the detection coil 15. The connecting rod 16 extends below the housing 14. A ball head 17 is fixedly installed at the bottom end of the connecting rod 16. Between the top end of the connecting rod 16 and the housing 14, they are fixedly connected by a return spring 18. A magnet 19 is fixedly installed on the outer surface of the connecting rod 16 inside the detection coil 15. The detection coil 15 is controlledly connected to the control telescopic rod 23. When moving from the side of the control telescopic rod 23 to the side of the fixed rod 5, the ball head 17 descends, indicating that the height on the side of the control telescopic rod 23 is higher than the height on the side of the fixed rod 5. At this time, the control telescopic rod 23 descends, and vice versa.

[0022] An inner and outer sliding frame 6 is fixedly connected between each group of bases 1. A threaded block 7 is fixedly installed in the middle of the inner sliding frame. A lead screw 8 is threadedly connected in the middle of the threaded block 7. The lead screw 8 is rotatably connected to the base 1 to which the outer sliding frame is fixedly connected. Through such a setting, the distance between the bases 1 can be adjusted to support sheet metal parts of different lengths.

[0023] A collar 20 is fixedly installed on the outer surface of the housing 14. The free end of the adjusting telescopic rod 13 is fixedly connected to the collar 20. The collar 20 serves to connect the housing 14 and the adjusting telescopic rod 13.

[0024] A sliding block 21 is fixedly installed at the top of the outer shell 14. The cross-sectional shape of the sliding block 21 is "concave". The sliding block 21 is slidably connected below the fixed frame 11. Through such a setting, the sliding block 21 can be clamped inside the fixed frame 11 and can slide relative to the fixed frame 11.

[0025] The separate base 1 and the fixed frame 11 are fixedly connected at least through three control telescopic rods 23 or fixed rods 5. The three control telescopic rods 23 and the fixed rods 5 are equidistantly distributed. Through such a setting, the force on the device can be ensured to be uniform.

[0026] During use, sheet metal parts with different thicknesses are respectively arranged above the fixed frame 11, and the moving pressure plate 22 is used to fix the sheet metal parts by rotating the threaded shaft 4. Adjust the position so that the two sheet metal parts are in contact with each other. The detection head 12 is arranged at the connection gap between the two sheet metal parts. Starting the adjustment telescopic rod 13 can drive the detection head 12 to move back and forth. When the upper surfaces of the two sheet metal parts are not in the same horizontal plane, the ball head 17 will displace during the movement, so that the magnet 19 can move in position, and then the detection coil 15 generates an electric current. After the current is generated, control the adjustment telescopic sleeve 10 to move up and down to level the two sheet metal parts until the ball head 17 moves and the magnet 19 no longer moves up and down to complete the welding support adjustment of the two sheet metal parts, so that the welding support of two sheet metal parts with different thicknesses can be ensured and the connection surface is horizontal.

[0027] By providing the inner and outer sliding frames 6, the two bases 1 can slide along the inner and outer sliding frames 6. By providing the threaded block 7 and the lead screw 8, the distance between the two bases 1 can be adjusted, so that the distance between the two bases 1 can be increased or decreased, and finally the adaptation support for sheet metal parts of different sizes can be realized.
