Furthermore, the height of the adjusting plate can be adjusted by adjusting the position of the adjusting block inside the clamping plate, so that low-voltage switchgear of different heights can be clamped, thus completing the clamping work.

[0017] By incorporating a height adjustment mechanism, when the height of the placement platform needs to be adjusted, the worm gear and worm wheel work together to drive the screw to rotate. When the screw rotates, the screw sleeve moves to the outside of the screw. When the screw rotates clockwise, the screw sleeve moves upward, thereby adjusting the height of the placement platform. This allows the user to adjust the height of the placement platform according to their needs, thus completing the height adjustment task. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model embodiment provides a welding fixture for processing low-voltage switchgear, such as... Figures 1-5 As shown, it includes a base 1 and a placement platform 3; the top of the base 1 is provided with a placement platform 3, the inside of the placement platform 3 is provided with a clamping structure 4, guide rods 5 are installed on both sides and both ends of the top of the base 1, and a height adjustment structure 2 is provided at the middle position of the top of the base 1.

[0026] The height adjustment structure 2 includes a mounting box 202, which is fixed to the top of the base 1. A worm gear 203 is installed inside the mounting box 202. A worm 201 is installed on one side of the worm gear 203. A screw 208 is fixed to the top of the worm gear 203. A fixing sleeve 204 is fixed to the top of the mounting box 202. A screw sleeve 207 is installed on the outside of the screw 208. The top of the screw sleeve 207 is fixed to the bottom of the placement platform 3. A guide groove 205 is opened inside the fixing sleeve 204. A guide block 206 is inserted inside the guide groove 205. One side of the guide block 206 is fixed to one side of the screw sleeve 207. An external thread is provided on the outside of the screw 208. An internal thread is provided on the inside of the screw sleeve 207. A threaded connection is formed between the screw sleeve 207 and the screw 208. Two sets of guide blocks 206 are provided. A guide connection is formed between the guide blocks 206 and the guide groove 205.

[0027] In a further preferred embodiment of this utility model, such as Figures 1-5 As shown: Before welding the low-voltage switchgear, the height of the placement platform 3 is adjusted according to the operator's needs. During adjustment, the worm gear 201 is rotated, which drives the worm wheel 203 to rotate. The worm wheel 203, in turn, drives the screw sleeve 207 to rotate via the screw 208. When the screw sleeve 207 rotates, the cooperation between the guide groove 205 and the guide block 206 guides the screw sleeve 207, causing the screw sleeve 207 to move outside the screw 208 when the screw 208 rotates. When the screw 208 rotates clockwise, the screw sleeve 207 moves upward, thereby adjusting the height of the placement platform 3. This allows the user to adjust the height of the placement platform 3 according to their needs, thus completing the height adjustment work of the placement platform 3.

[0028] The clamping structure 4 includes a bidirectional lead screw 405, which is installed inside the placement platform 3. A motor 401 is installed on one side of the bidirectional lead screw 405, and a threaded sleeve 406 is installed on the outer side of the bidirectional lead screw 405. A clamping plate 402 is fixed to the top of the threaded sleeve 406. An adjusting block 404 is inserted inside the clamping plate 402, and an adjusting plate 403 is fixed to the top of the adjusting block 404. A rotating groove 408 is opened inside one side of the clamping plate 402, and a rotating rod 407 is installed inside the rotating groove 408. Two sets of clamping plates 402 are provided, and the two sets of clamping plates 402 are symmetrically distributed at the top of the placement platform 3. Two sets of threaded sleeves 406 are provided, and the two sets of threaded sleeves 406 are threadedly connected to the bidirectional lead screw 405.

[0029] In a further preferred embodiment of this utility model, such as Figures 1-5As shown: After the height of the placement platform 3 is adjusted, the low-voltage switchgear to be welded is placed on the top of the placement platform 3. After placement, the external power supply is connected to start the motor 401. After the motor 401 starts, it drives the bidirectional lead screw 405 to rotate. When the bidirectional lead screw 405 rotates, it drives the two sets of clamping plates 402 to move towards the middle position through the cooperation of the lead sleeve 406, thereby clamping the low-voltage switchgear and preventing it from moving around during welding, thus completing the clamping work. During clamping, the height of the adjusting plate 403 is adjusted by adjusting the position of the adjusting block 404 inside the clamping plate 402. After the height of the adjusting plate 403 is adjusted, the rotating rod 407 is rotated. As the rotating rod 407 rotates with the rotating groove 408, it pushes the pressing block at one end of the rotating rod 407 against one side of the adjusting block 404 to fix the adjusting plate 403, so that it can clamp low-voltage switchgear of different heights, thus completing the clamping work.
