A first motor 11 used in conjunction with the first gear 12 is fixedly installed on the cross bar 4. The driving end of the first motor 11 is fixedly connected to one side of the first gear 12. The first motor 11 can drive the first gear 12 to rotate through the driving end. With the rotation of the first gear 12, the second gear 18 and the threaded rod 8 can be synchronously rotated. With the rotation of the threaded rod 8, the threaded slider 5 can move back and forth; A protrusion 21 is arranged inside the slider 5, and the threaded rod 8 is threaded through the protrusion 21. The inner wall of the cross bar 4 is an inclined surface 19. The protrusion 21 is slidably connected with the surface of the inclined surface 19. A plurality of pulleys 22 are rotatably installed on both sides of the slider 5. The pulleys 22 are in contact with the surface of the inclined surface 19. The threaded rod 8 is threaded through the protrusion 21. When the threaded rod 8 rotates, the slider 5 can be driven to move back and forth through the protrusion 21. The pulleys 22 are arranged on both sides of the slider 5. The rolling pulleys 22 can reduce the friction force during the movement of the slider 5. A baffle 20 is fixedly installed on one end of the cross bar 4. The first gear 12 is rotatably connected with the baffle 20 through a rotating shaft, and the first gear 12 supports the baffle 20. A second driving mechanism is provided at both ends of the crossbar 4, and the second driving mechanism includes two rollers 13, and the two rollers 13 are in contact with the outer surface of the slide groove 3. The second driving mechanism also includes a linkage shaft 15, and both ends of the linkage shaft 15 are rotatably connected with a movable shaft 14, and the roller 13 is fixedly connected to one end of the linkage shaft 15 through a rotating shaft. The end of the crossbar 4 is fixedly connected to a support plate 10 used in conjunction with the second driving mechanism, and a second motor 17 is fixedly installed on the support plate 10. The driving end of the second motor 17 is fixedly connected to a turntable 16, and the linkage shaft 15 is rotatably connected to the edge position of the turntable 16 When it is necessary to drive the cross bar 4 to move back and forth on the mobile frame 2, the second motor 17 drives the turntable 16 to rotate through the driving end, and the turntable 16 drives the linkage shaft 15 to move. When the linkage shaft 15 moves, the movable shaft 14 connected at both ends drives the roller 13 to rotate, so that the cross bar 4 can move back and forth on the mobile frame 2. A rotating member is provided at the edge of the turntable 16, and the rotating member is rotatably connected to the middle section of the linkage shaft 15.

Grid lines are provided on the surface of the operating table 1, and the grid lines are used for aiming and alignment.

[0020] In the embodiment of the application of the above technical solution, the metal casting to be cut is transported from one side of the entrance and exit to the operating table 1, and the first driving mechanism and the second driving mechanism move the position of the slider 5, so that the slider 5 can be moved to any position on the surface of the operating table 1, thereby cutting the metal casting.

[0021] The first motor 11 in the first driving mechanism drives the first gear 12 to rotate through the driving end, and the first gear 12 is meshed with the second gear 18.

When the slider 5 moves, the pulley 22 rolls along the surface of the inclined surface 19. The rotating pulley 22 can reduce the friction force during the back and forth movement of the slider 5. The laser cutting machine 6 can move back and forth on the cross bar 4 through the first driving mechanism, and the movement in the X-axis direction is realized.

[0022] The second motor 17 in the second driving mechanism drives the turntable 16 to rotate. The edge of the turntable 16 is rotatably connected with a linkage shaft 15. Since the linkage shaft 15 is connected to the edge of the turntable 16, the linkage shaft 15 will make a circular motion with the driving end of the second motor 17 as the center. As the linkage shaft 15 moves, the movable shafts 14 at both ends can be driven to move. The movable shaft 14 drives the roller 13 to rotate. The rotating roller 13 can drive the cross bar 4 to move back and forth on the movable frame 2, thereby realizing the movement of the laser cutting machine 6 in the Y-axis direction.

[0023] The first driving mechanism and the second driving mechanism cooperate with each other to realize the movement of the laser cutting machine 6 on the surface of the operating table 1 and the cutting effect on the metal casting. Only part of the laser cutting machine 6 is moved, which can greatly reduce the demand for kinetic energy and thus reduce the manufacturing cost of the equipment.

These improvements and modifications should also be regarded as the scope of protection of the present invention.
