The two ends of the screw 402 continue to move through the outside of the two side plates 401 away from each other, and are respectively fixedly sleeved with a spur gear 403. The rotation of the spur gear 403 causes the screw 402 to rotate and drives the slide plate 404 to move along the bottom of the bottom plate 3, thereby generating a linkage effect. A dual-axis motor 5 is fixedly installed on the top of the bottom plate 3. The two output shafts of the dual-axis motor 5 are connected with a rotating rod 6. The ends of the two rotating rods 6 away from the dual-axis motor 5 are fixedly sleeved with a spur gear 2 7, and the two spur gears 2 7 mesh with the two spur gears 1 403. The rotation of the two rotating rods 6 drives the spur gear 2 7 to rotate, and the meshing drives the spur gear 1 403 to rotate, thereby generating a linkage effect.

[0026] In this embodiment, the dual-axis motor 5 of the starting cabinet causes the two rotating rods 6 to rotate and drive the spur gear 2 7 to rotate, and mesh with the spur gear 1 403, so that the screw 402 rotates and drives the slide plate 404 to move along the bottom of the base plate 3, and drives the gear ring 406 to move synchronously through the rotating shaft 405, and the gear ring 406 rotates on the rack 410, and drives the rocker arm 407 to rotate, and the direction of the moving wheel 408 is also turned 180 degrees, and it can be freely switched according to the different load-bearing directions of the gantry milling equipment, so as to meet the load-bearing requirements of the heavier side during the movement.

[0027] Example 2

[0028] like Figure 1-4 As shown, the two side plates 409 are symmetrically installed with L plates 8 on the side away from each other, and a baffle 9 is fixedly connected between the tops of the two L plates 8. The baffle 9 blocks the top of the dual-axis motor 5, and the baffle 9 blocks and protects the top of the dual-axis motor 5. The L plates 8 on both sides block and protect the adjacent gears. The four corners of the bottom of the bottom plate 3 are fixedly installed with legs 10, and the bottoms of the four legs 10 are installed with casters 11. The casters 11 contact the ground to facilitate the transportation and site transfer of the equipment. Hydraulic rods 12 are arranged at the four corners of the top of the bottom plate 3, and the bottom ends of the inner rods of the four hydraulic rods 12 are respectively fixedly connected to the four corners of the top of the bottom plate 3, and the tops of the outer rods of the four hydraulic rods 12 are fixedly sleeved with sleeve discs 13, and each sleeve disc 13 is respectively provided with There are four mounting holes 14. The inner rod extension of the hydraulic rod 12 can push the base plate 3 down so that the legs 10 support the entire gantry milling equipment. Conversely, the inner rod contraction of the hydraulic rod 12 can drive the base plate 3 to rise, so that the casters 11 are away from the ground, so that the gantry milling base 1 is in contact with the ground for stable placement. A mounting groove corresponding to the mounting hole 14 is provided on the top of the inner wall of the gantry milling base 1. A bolt is threadedly connected between the inner wall of each mounting hole 14 and the inner wall of the corresponding mounting groove. A gantry milling assembly 2 is installed on the top of the gantry milling base 1. The bolts penetrate the mounting holes 14 and the screw grooves to install and adapt the sleeve 13, so that the four hydraulic rods 12 are installed on the gantry milling base 1. Conversely, the device in this case can be quickly disassembled by loosening the bolts.

[0029] In this embodiment, a corresponding screw groove is opened at the bottom of the gantry milling base 1, so that the bolt passes through the mounting hole 14 and the screw groove to install and adapt the sleeve 13, thereby installing the four hydraulic rods 12 on the gantry milling base 1, and the structure in this case is adapted to any gantry milling equipment with a base, which is convenient for moving and transporting the equipment. The inner rod extension of the hydraulic rod 12 can push the base plate 3 down, thereby driving the support leg 10 to descend, and allowing the caster 11 and the moving wheel 408 to contact the ground, thereby supporting the entire gantry milling equipment for convenient and quick movement.

[0030] When a gantry CNC milling machine of the utility model is in use, the gantry milling base 1 and the gantry milling assembly 2 in this case are one of the basic structures of the gantry milling machine of the prior art CNC machine tool, including linear motors, spindles, work tables, etc., which are not described in detail in this case. In this case, a secondary improvement is made based on the mobile structure of the comparative patent publication number CN213258115U. By opening a corresponding screw groove at the bottom of the existing gantry milling base 1, the bolt passes through the mounting hole 14 and the screw groove to install and adapt the sleeve 13, so that the four hydraulic rods 12 are installed on the gantry milling base 1, and the structure in this case is adapted to any gantry milling equipment with a base, which is convenient for The equipment is moved and transported. The inner rod of the hydraulic rod 12 is extended to push the bottom plate 3 down, thereby driving the legs 10 down and allowing the casters 11 and the moving wheels 408 to contact the ground, thereby supporting the entire gantry milling equipment. The equipment is convenient and quick to move, and the equipment is transported and transferred to the site, reducing the pressure of manual transportation. Conversely, the inner rod of the hydraulic rod 12 is contracted to drive the bottom plate 3 to rise, thereby moving the casters 11 away from the ground, and allowing the gantry milling base 1 to contact the ground for stable placement. The operation is simple and convenient to use. Different gantry milling equipment has different configurations, and the equipment needs to be equipped with a CNC computer. The computer is located on either side of the gantry milling base 1. This causes one side of the equipment to become heavier. Therefore, according to the current weight bias direction of the gantry milling equipment, the cabinet double-axis motor 5 can be started to make the two rotating rods 6 rotate to drive the spur gear 2 7 to rotate, and mesh to drive the spur gear 1 403 to rotate, so that the screw 402 rotates to drive the slide plate 404 to move along the bottom of the bottom plate 3. During the displacement process, the gear ring 406 is driven to move synchronously through the rotating shaft 405, and the gear ring 406 is meshed on the rack 410 to rotate, and drives the rocker arm 407 to rotate, so that when the slide plate 404 moves to the other side of the initial position, the direction of the moving wheel 408 is also turned 180 degrees. This method can be used according to the weight bias direction of the gantry milling equipment. The weight direction can be switched freely to meet the requirements of enhanced load-bearing capacity on the heavier side during movement. The heavier side has two casters 11 plus a mobile wheel 408 to share the load-bearing force, making it more stable during movement and transportation, and will not cause one side to be too heavy, resulting in tilting and damage to the wheels. The bottom plate 3 blocks and protects the bottom of the dual-axis motor 5, and the baffle 9 blocks and protects the top of the dual-axis motor 5, and limits the height after the overall rise to avoid squeezing damage between the dual-axis motor 5 and the gantry milling base 1. The L-plates 8 on both sides block and protect the adjacent gears to prevent damage caused by external forces and foreign objects during movement and use.
