[0031] The above-mentioned various structures jointly constitute the general appearance structure of the welding tool for forklift production.

[0032] In order to further explain the specific working principle of the welding tool for the forklift production, the lifting device 4 comprises a threaded block 404 rotatably connected to the middle part of the bottom end of the supporting plate 3, then a screw rod 403 is threadedly connected to the threaded block 404, when the screw rod 403 rotates, the threaded block 404 can be driven to rise or fall, then the threaded block 404 can push the supporting plate 3 to rise or fall, then a worm wheel 402 is fixedly connected to the bottom end of the screw rod 403, then a worm 405 is engaged on one side of the worm wheel 402, in order to drive the worm 405, a motor 407 is fixedly connected to the rear end of the worm 405, wherein the motor 407 is fixedly connected to the base 1 through the motor seat 408, at this time, the effect achieved is that the motor 407 drives the worm 405 to rotate, the worm 405 can drive the worm wheel 402 to rotate, then a baffle 406 is rotatably connected to the front end of the worm 405, it is worth noting that the baffle 406 is fixedly connected to the base 1, at the same time, a rotating shaft 401 is fixedly connected to the middle part of the bottom end of the worm wheel 402, and the bottom end of the rotating shaft 401 is rotatably connected to the middle part of the top end of the base 1.

[0033] The technical effect achieved by the technical scheme composed of the above technical features is that when it is necessary to change the height of the supporting plate 3, the motor 407 first drives the worm 405 to rotate, then the worm 405 rotates on the baffle 406, since the worm 405 and the worm wheel 402 are engaged, the worm 405 drives the worm wheel 402 to rotate at the same time, when the worm wheel 402 rotates, the rotating shaft 401 rotates on the base 1, and the screw rod 403 also rotates at the same time, when the screw rod 403 rotates, the threaded block 404 threadedly connected to the screw rod 403 pushes the supporting plate 3 to the specified position.

[0034] In order to further explain the specific working principle of the welding tool for forklift production, the translation device 10 includes two rotating frames 1002 fixedly connected to the rear of the top end of the support plate 3. It is worth noting that the two rotating frames 1002 are symmetrically arranged at the rear of the top end of the support plate 3. Then, the front of the proximal side of the two rotating frames 1002 is rotatably connected with a second screw rod 1004, and one end of the second screw rod 1004 penetrates the rotating frame 1002 and is fixedly connected with a second motor 1005. The second motor 1005 is fixedly connected to the support plate 3 through a second motor seat 1006. Then, a sliding block 1001 is threadedly connected to the second screw rod 1004, and the sliding block 1001 is fixedly connected to the bottom end of the connecting column 9. It is worth noting that the threaded relationship between the second screw rod 1004 and the sliding block 1001 has self-locking property. The bottom end of the sliding block 1001 is slidably connected to the support plate 3. As a result, the second motor 1005 drives the second screw rod 1004 to rotate, and the second screw rod 1004 drives the sliding block 1001 to displace. The rear of the proximal side of the two rotating frames 1002 is fixedly connected with a guide rod 1003, wherein the guide rod 1003 is inserted into the sliding block 1001, and it is worth noting that the guide rod 1003 is located behind the second screw rod 1004.

[0035] The technical effect achieved by the technical scheme composed of the above technical features is that when the sliding block 1001 needs to displace the connecting column 9, the second motor 1005 first drives the second screw rod 1004 to rotate. At the same time that the second screw rod 1004 rotates, the sliding block 1001 threadedly connected with the second screw rod 1004 starts to displace on the support plate 3, and the sliding block 1001 also starts to displace on the guide rod 1003. When the connecting column 9 reaches the appropriate position, the second motor 1005 stops rotating. Since the threaded relationship between the second screw rod 1004 and the sliding block 1001 has certain self-locking property, at this time, the sliding block 1001 does not displace any more after the second motor 1005 stops rotating, thereby ensuring the processing precision.
