The surface of the guide rail block 2 is provided with a guide rail groove 21 along the length direction. The side walls on both sides of the welding table 3 are welded and fixedly provided with moving blocks 31 adapted to be inserted into the guide rail groove 21. Moving wheels 32 are also rotatably arranged on both sides of the welding table 3, and the moving wheels 32 are adapted to be inserted into the guide rail groove 21 and abut against the bottom wall of the guide rail groove 21. The side wall of the welding table 3 is provided with an assembly groove 33, and a lifting column 4 is welded and fixed on the transmission block 7. The lifting column 4 is arranged on both sides of the guide rail block 2. The side wall of the lifting column 4 is provided with a lifting groove 41, and a lifting block 42 is slidingly arranged in the lifting groove 41. The side wall of the lifting block 42 is integrally provided with a lifting plate 421 that can be inserted into the assembly groove 33. The lifting column 4 is provided with a lifting assembly 5 for driving the lifting block 42 to rise and fall. The object to be welded is placed on the welding table 3, and the welding table 3 is pushed so that the moving wheel 32 rotates until it abuts against the inner wall of one side of the guide rail groove 21, so that the welding table 3 moves to the bottom of the welding head 111. During this process, the lifting plate 421 is inserted into the assembly groove 33. At this time, the lifting block 42 and the welding table 3 are driven by the lifting assembly 5 to rise close to the welding head 111, and then the moving device 112 can be operated to perform welding through the welding head 111. By setting up a movable and liftable welding table 3, the convenience of transportation and overall use is improved. The welding table 3 or objects on the welding table 3 can also be lifted and lowered by a forklift or other auxiliary equipment. However, in relatively small areas or areas such as laboratories where forklifts are difficult to enter and exit, the movable and liftable welding table 3 of the present application can greatly improve the convenience of carrying welding objects.

The lifting screw 52 is inserted into the transmission cavity 71 and is coaxially fixedly connected to the second transmission sprocket 62. When lifting is required, the lifting motor 51 is started to drive the first transmission sprocket 61 to rotate. The rotation of the first transmission sprocket 61 drives the second transmission sprocket 62 to rotate through the transmission chain 63, thereby driving the lifting screw rod 52 to rotate, driving the lifting block 42 to rise or fall in the lifting slot 41, and completing the lifting.

[0035] The implementation principle of a floor-standing gantry-type lifting laser welding machine tool in the embodiment of the present application is as follows: push the welding table 3 so that the moving wheel 32 rotates in the guide groove 21, drive the welding table 3 away from the lifting motor 51, place the object to be welded on the welding table 3, push the welding table 3 so that the moving wheel 32 moves in the guide groove 21 until it abuts against the inner wall of the guide groove 21, at this time, the welding table 3 is located below the welding table 3, and the lifting plate 421 is adapted to be inserted into the assembly groove 33. Start the lifting motor 51, the lifting motor 51 drives the lifting screw 52 to rotate through the transmission assembly 6, thereby driving the lifting block 42 in the lifting groove 41, driving the welding table 3 to rise close to the welding head 111, and in this process, the positioning rod 431 is adapted to pass through the first positioning hole 422 and the second positioning hole 34. Then, the welding head 111 is operated to move through the moving device 112 for welding.

[0036] After welding is completed, the lifting motor 51 is started to drive the lifting screw 52 to rotate through the transmission assembly 6, thereby driving the lifting block 42 to descend, driving the welding table 3 to descend so that the moving block 31 and the moving wheel 32 are adapted to be inserted into the guide rail groove 21, pushing the welding table 3 so that the moving wheel 32 rotates in the guide rail groove 21, driving the welding table 3 away from the lifting motor 51, and the welded object can be taken out at this time.
