[0027] During use, a limit plate 3 is set, and a positioning groove 4 is opened on the surface of the limit plate 3. When the machine tool beam 2 is reset, the hydraulic cylinder 7 can be started to displace the positioning plate 8 set at one end of the hydraulic cylinder 7, so that the positioning plate 8 can be quickly inserted into the positioning groove 4 opened on the limit surface, thereby increasing the rigidity of the machine tool beam 2 and moving quickly. Through the setting of the hydraulic cylinder 7, the positioning plate 8 can be tightly pressed against the inside of the positioning groove 4 without the help of other systems to obtain lasting pulling force, thereby saving energy and being safe and reliable. Embodiment 2

[0028] On the basis of the first embodiment, in order to facilitate the fixing of the machine tool crossbeam 2, a hydraulic cylinder 7 is provided, the limit plate 3 is fixedly connected to the side of the machine tool column 1, and the positioning grooves 4 provided on the surface of the limit plate 3 are provided with multiple groups, and the multiple groups of positioning grooves 4 are regularly arranged linearly with respect to the surface of the limit plate 3. A fixing plate 9 is provided on the surface of the hydraulic cylinder 7, and the fixing plate 9 is provided with two groups. The two groups of fixing plates 9 are symmetrically distributed up and down about the hydraulic cylinder 7. The positioning plate 8 is fixedly connected to the lifting end of the hydraulic cylinder 7, and the positioning plate 8 can be inserted into the positioning groove 4;

[0029] When in use, first fix the hydraulic cylinder 7 inside the mounting plate 5, and then use the hydraulic cylinder 7 to push the positioning plate 8 so that the positioning plate 8 is inserted into the positioning groove 4 provided on the surface of the limit plate 3, so that the machine tool beam 2 can be fixed. There are multiple groups of positioning grooves 4, which are convenient for adjusting the machine tool beam 2 to be fixed on the machine tool column 1 at multiple positions to improve practicality. Embodiment 3

[0030] On the basis of the second embodiment, in order to facilitate the installation and disassembly of the hydraulic cylinder 7, a mounting plate 5 is provided, the mounting plate 5 is fixedly connected to the side of the machine tool beam 2, two groups of mounting plates 5 are provided, and the two groups of mounting plates 5 are symmetrically distributed about the machine tool beam 2, a baffle 10 is provided in the placement groove 6, and the baffle 10 is an "L"-shaped plate structure as a whole, and a lifting groove 11 is provided on the surface of the baffle 10, and the fixed plate 9 can be stuck between the two groups of baffles 10, and a vertical rod 12 is provided in the lifting groove 11, and a spring 13 and a lifting plate 15 are sleeved on the surface of the vertical rod 12. A thread is provided at one end of the vertical rod 12, and a positioning nut 14 is screwed on the thread surface. One end of the spring 13 is fixedly connected to the surface of the lifting plate 15, and the other end of the spring 13 can be against the bottom of the positioning nut 14, and the lifting plate 15 can slide on the vertical rod 12, and a second fixed plate 16 is provided on the side of the lifting plate 15, and the second fixed plate 16 can be against the side of the fixed plate 9;

The setting of the spring 13 prevents the lifting plate 15 from sliding freely on the vertical pole 12, and it is more convenient to take out the lifting plate 15 when the positioning nut 14 is rotated out of the vertical pole 12.

[0032] Working principle: In actual use, a limit plate 3 is set, and a positioning groove 4 is opened on the surface of the limit plate 3. When the machine tool beam 2 is reset, the hydraulic cylinder 7 can be started to displace the positioning plate 8 set at one end of the hydraulic cylinder 7, so that the positioning plate 8 is quickly inserted into the positioning groove 4 opened on the limit surface, thereby increasing the rigidity of the machine tool beam 2, and the action is fast. The setting of the hydraulic cylinder 7 can make the positioning plate 8 tightly against the inside of the positioning groove 4 without the help of other systems to obtain lasting pulling force, thereby saving energy, and being safe and reliable. This avoids the traditional mechanical clamping box and long clamping plate used between the traditional machine tool beam 2 and the machine tool column 1, which require manual operation, large assembly workload, unstable clamping state, and low work efficiency.
