[0001] The present invention relates to the technical field of laser cutting equipment, and in particular to a laser cutting equipment with a multi-angle adjustment structure. Background Art

[0002] Laser cutting machine is to focus the laser emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. As the relative position of the beam and the workpiece moves, the material is finally cut to achieve the purpose of cutting. When cutting, the existing laser cutting machine can only keep a vertical state with the workpiece body for vertical cutting, and cannot adjust the angle to perform comprehensive cutting of the special-shaped workpiece body. Some existing laser cutting machines achieve side cutting or slope cutting of the workpiece by adjusting the angle of the laser cutting head. However, the body of the laser cutting machine with the above structure is subject to the limitation of the maximum tilt angle range. It cannot directly process some workpieces with complex shapes and special angles or requires multiple clamping, which increases the difficulty of operation and reduces the possibility of product innovation, especially in three-dimensional cutting and complex curved surface processing.

[0018] Please pay attention to Figure 1-2 The first driving component includes a first servo motor 13, which is fixedly mounted on the upper end of the cutting workbench 1. A first gear 131 is fixedly mounted on the output shaft end of the first servo motor 13. The shape of the rotating table 2 is circular. The outer ring of the rotating table 2 is provided with a plurality of tooth blocks matching the first gear 131. The tooth blocks are meshed with the first gear 131. The first gear 131 is driven to rotate by the rotation of the output shaft of the first servo motor 13. The first gear 131 pushes the tooth blocks to drive the rotating table 2 to rotate in the horizontal direction.

[0019] Please pay attention to Figure 1 , Figure 2 , Figure 4 The second driving component includes a second servo motor 223, wherein the second servo motor 223 is fixedly mounted on one of the clamping seats 22, and the output shaft of the second servo motor 223 passes through the clamping seat 22 and is fixedly connected to the clamping piece 222. The second servo motor 223 drives one of the clamping pieces 222 to rotate in the vertical direction. Since the workpiece is clamped between the two clamping pieces 222, only one of the clamping pieces 222 needs to be driven to drive the workpiece to rotate in the vertical direction.

[0020] Please pay attention to Figure 1-4 The rotating table 2 is provided with a strip groove, in which a bidirectional screw rod 21 is rotatably installed, and the two clamping seats 22 are respectively sleeved on the two ends of the bidirectional screw rod 21, and the rotation of the bidirectional screw rod 21 drives the two clamping seats 22 to approach or move away from each other, and the rotation of the bidirectional screw rod 21 drives the two clamping seats 22 to approach or move away from each other synchronously, thereby realizing the operation of clamping and releasing the workpiece by the clamping piece 222, and a square protrusion extends outward from one side of the clamping seat 22, and the protrusion is movably installed in the strip groove, and the shape of the protrusion is consistent with the shape of the strip groove, and a through screw hole 221 is provided in the middle of the protrusion, and the bidirectional screw rod 21 passes through the screw hole 221 and the The clamp seat 22 is movably connected, and the clamp seat 22 is driven to move by the two-way screw rod 21 cooperating with the screw hole 221. The protrusion limits the clamp seat 22, so that the clamp seat 22 can move back and forth along the length direction of the strip groove. A third servo motor 23 is fixedly installed on the rotating table 2, and a worm gear 231 is fixedly installed on the output shaft of the third servo motor 23. A worm 211 is sleeved on the middle part of the two-way screw rod 21. The worm gear 231 and the worm 211 are transmitted through spiral contact. The worm gear 231 is driven to rotate by the output shaft of the third servo motor 23, thereby driving the worm 211 and the two-way screw rod 21 to rotate, thereby realizing the electric control of the two clamp seats 22 approaching and moving away.

[0021] Please pay attention to Figure 4 A plurality of anti-skid convex balls are arranged on the opposite side of the clamping piece 222, and the anti-skid convex balls increase the friction force of the clamped workpiece to prevent the workpiece from falling off during processing.

[0022] Please pay attention to Figure 1 When the clamp 222 clamps the workpiece, the workpiece is located directly below the laser cutting machine body 12, so that the laser cutting machine can accurately locate the position and angle of the workpiece. When the workpiece is rotated to adjust the angle, it is located in the center of the laser cutting machine, ensuring the accuracy and quality of cutting and improving the processing accuracy.

[0023] The working principle of the first embodiment of the present invention is as follows: When in use, the workpiece is correctly placed between the two clamping pieces 222, and the third servo motor 23 is started. The output shaft of the third servo motor 23 rotates to drive the worm gear 231 to rotate, and the worm gear 231 drives the worm 211 to drive the bidirectional screw rod 21 to rotate, so that the clamping seat 22 and the clamping piece 222 are close to each other to clamp and fix the workpiece, and the clamped workpiece is cut and processed by the laser cutting machine body 12; The workpiece can be beveled by adjusting the inclination angle of the laser gas cutting machine body itself, and the first servo motor 13 is started at the same time. The output shaft of the first servo motor 13 rotates to drive the first gear 131 to rotate, and the first gear 131 drives the rotating table 2 to rotate around its own center, thereby driving the workpiece to rotate in the horizontal direction. The translation and inclination angle adjustment of the laser cutting machine body 12 are coordinated to accurately cut the top and side of the workpiece. When the bottom of the workpiece needs to be processed, the second servo motor 223 is started, and the rotation of the second servo motor 223 drives the clamp 222 to rotate in the vertical direction. Since the two clamps 222 tightly clamp the workpiece, the workpiece is rotated in the vertical direction, and the bottom range of the workpiece is rotated toward the direction of the laser cutting machine body 12, so that the bottom of the workpiece can be cut. By rotating the workpiece in the horizontal direction and in the vertical direction, the ideal cutting angle can be achieved by adjusting the inclination angle of the laser cutting machine body 12, reducing the time cost of manual intervention, adapting to the cutting of workpieces with complex curved surfaces or special shapes, and meeting diverse cutting processing needs.

It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method.
