This will cause the crossbeam to move slightly during the processing due to external forces or the vibration of the machine tool itself, thereby affecting the processing accuracy and workpiece quality. In addition, the crossbeam without a clamping device may also pose a safety hazard, such as operator injury or machine damage due to accidental movement. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0015] See also Figure 1-3 The utility model provides a crossbeam clamping device for a vertical lathe, comprising two brackets 1, two hydraulic cylinders 2 and a crossbeam 3. The two brackets 1 are arranged one on the left and one on the right. The two hydraulic cylinders 2 are located between the two brackets 1, and the two hydraulic cylinders 2 are arranged one on the left and one on the right. The bottom of the crossbeam 3 is connected to the driving ends of the two hydraulic cylinders 2, and the crossbeam 3 is slidably connected to the two brackets 1. Positioning grooves 4 are provided on the left and right sides of the crossbeam 3. Two clamping structures are provided on the outer sides of the two brackets 1, and the two clamping structures are symmetrically arranged on the left and right.
[0016] Specifically, the clamping structure includes two mounting frames 5, a support box 6, a bidirectional screw 7, a motor 8, two first slide rails 9, two moving blocks 10, two sets of support rods 11, two connecting seats 12, a moving plate 13 and a plurality of clamping blocks 14. The two mounting frames 5 are arranged on the outside of the bracket 1, and the two mounting frames 5 are arranged one above and one below. The support box 6 is arranged between the two mounting frames 5. The bidirectional screw 7 is rotatably connected to the top and bottom of the support box 6 and the two mounting frames 5 respectively. The motor 8 is arranged on the mounting frame 5, and the driving end of the motor 8 is connected to one end of the bidirectional screw 7. Then, the two first slide rails 9 are arranged on the right side of the support box 6, the two moving blocks 10 are movably connected to the reverse threads of the bidirectional screw 7, and the two moving blocks 10 are slidably connected to the two first slide rails 9, one end of the two groups of support rods 11 are movably connected to the front and rear sides of the two moving blocks 10, the two connecting seats 12 are movably connected to the other ends of the two groups of support rods 11, the right side of the moving plate 13 is connected to the left sides of the two connecting seats 12, and a plurality of card blocks 14 are arranged on the left side of the moving plate 13, and any card block 14 matches the positioning groove 4 of the beam 3.
[0017] Specifically, two second slide rails 15 are provided at the top and bottom of the support box 6, and the two second slide rails 15 are slidably connected to the movable plate 13. The second slide rails 15 are used to auxiliary support the movable plate 13 to further improve the stability of the movable plate 13 when moving.
[0018] Specifically, the bidirectional screw 7 is connected to the support box 6 via a bearing, the inner ring of the bearing is interference fit with the bidirectional screw 7 , and the outer ring of the bearing is fixedly connected to the support box 6 .
[0019] Working principle: First, driven by the cylinder, the beam 3 moves up and down between the two brackets 1. During this process, the bottom of the beam 3 is connected to the driving end of the hydraulic cylinder 2, ensuring the stability and accuracy of the movement of the beam 3. At the same time, the sliding connection design between the beam 3 and the bracket 1 enables the beam 3 to achieve flexible movement while maintaining stability. When the cross beam 3 moves to the designated position, the clamping structure is then started to fix it, and the motor 8 drives the bidirectional screw 7 to rotate. Since the bidirectional screw 7 is rotatably connected to the top and bottom of the support box 6 and is movably connected to the two moving blocks 10, when the bidirectional screw 7 rotates, the two moving blocks 10 will move linearly toward each other along the first slide rail 9, one end of the support rod 11 is movably connected to the moving block 10, and the other end is movably connected to the connecting seat 12, so the movement of the moving block 10 will drive the support rod 11 and the connecting seat 12 to move together, thereby pushing the moving plate 13 to approach the cross beam 3. The moving plate 13 is provided with a plurality of blocks 14, and the shapes and sizes of these blocks 14 match the positioning grooves 4 on the cross beam 3. When the moving plate 13 moves to a position close enough, the blocks 14 will be accurately inserted into the positioning grooves 4 of the cross beam 3, thereby clamping the cross beam 3. This clamping method is both firm and reliable, and can effectively prevent the cross beam 3 from displacement or vibration during processing.
