[0024] Reference Figure 1-Figure 4 A gantry support for a gantry machining center includes a crossbeam 1, and also includes: a first column 2 is fixedly arranged on one end of the crossbeam 1, and a mounting groove is provided at the bottom of the first column 2, so as to facilitate fixing the first column 2 and the crossbeam 1 and improve the use effect; a second column 3 is slidably arranged on the other end of the crossbeam 1, wherein a sliding seat 4 is fixedly arranged on the top of the second column 3, a sliding groove 401 is provided on the sliding seat 4, the crossbeam 1 is slidably arranged in the sliding groove 401, and a fastening bolt 402 is threadedly connected to the sliding seat 4, and the fastening bolt 402 is provided with two to six groups. Here, we prefer three groups, and the three groups of fastening bolts 402 are extended One end extending into the slide groove 401 is respectively abutted against the side wall of the beam 1. When in use, the sliding seat 4 slides along the beam 1 by pushing the second column 3 close to or away from the first column 2, which is convenient for adjusting the distance between the second column 3 and the first column 2 and improving the installation effect. After the adjustment is completed, the fastening bolt 402 is tightened to make it abut against the side wall of the beam 1, which can prevent the second column 3 from moving during normal use and affecting normal work; a ladder 5 is fixedly provided on one end of the beam 1, and the ladder 5 is close to the first column 2. When in use, the ladder 5 is fixedly provided on one end of the beam 1, which makes it convenient to climb onto the beam 1 for maintenance, thereby improving the maintenance efficiency.

[0025] When in use, by pushing the second column 3 closer to or away from the first column 2, the sliding seat 4 slides along the beam 1, which is convenient for adjusting the distance between the second column 3 and the first column 2 and improving the installation effect. After the adjustment is completed, the fastening bolt 402 is tightened to make it abut against the side wall of the beam 1, which can prevent the second column 3 from moving during normal use and affecting normal work; by fixing a ladder 5 on one end of the beam 1, it is convenient to climb onto the beam 1 for maintenance, thereby improving the maintenance efficiency, and a fence 6 is fixed on the beam 1 to improve the safety during maintenance.

[0026] Referring to Figure 1-Figure 3 , on both sides of the other end of the crossbeam 1, guiding grooves 101 are respectively formed. The long sides of the guiding grooves 101 are parallel to the long side of the crossbeam 1. On the inner walls of both sides of the sliding groove 401, guiding blocks are respectively fixedly arranged. The guiding blocks are respectively slidably connected in the corresponding guiding grooves 101. When in use, by forming the guiding grooves 101 on the crossbeam 1 and fixedly arranging the guiding blocks on the inner wall of the sliding groove 401, it can ensure the reliable sliding of the sliding seat 4 and the second upright post 3, and improve the use effect.

[0027] Referring to Figure 1-Figure 3 , on the other end of the crossbeam 1, a fixing plate 7 is fixedly arranged. Here, we preferably use bolts to fixedly connect the fixing plate 7 to the crossbeam 1, which is convenient for the installation and disassembly of the fixing plate 7. A hydraulic cylinder 8 is fixedly arranged on the fixing plate 7. The output end of the hydraulic cylinder 8 is fixedly connected to the sliding seat 4. When in use, by loosening the fastening bolt 402 and then starting the hydraulic cylinder 8 to push the sliding seat 4 to slide along the crossbeam 1, it is convenient to adjust the distance between the second upright post 3 and the first upright post 2, and improve the use effect.

[0028] Referring to Figure 1-Figure 4 , a fence 6 is fixedly arranged on the top of the crossbeam 1, and the fence 6 is arranged in a "U" - shaped structure, and the opening of the fence 6 faces the ladder 5. When in use, by fixedly arranging the fence 6 on the top of the crossbeam 1 and making the opening of the fence 6 face the ladder 5, it can improve the protection effect and prevent personnel from accidentally falling.

[0029] Referring to Figure 4 , we design the cross - section of the crossbeam 1 as a "field" - shaped structure. When in use, designing the cross - section of the crossbeam 1 as a "field" - shaped structure can increase the strength and stiffness of the crossbeam 1, enabling it to better withstand various forces and vibrations during workpiece processing, can reduce the weight of the crossbeam 1, improve the running speed and processing efficiency of the gantry machining center, and can also optimize the structural design, enabling the crossbeam 1 to better maintain stability while bearing force, and improving the processing accuracy and quality.
