[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Figure 1-6As shown, this utility model provides a diamond laser cutting machine, including a processing table 1, a processing chamber 11 fixedly arranged in the middle of the processing table 1, a laser cutting mechanism 2 arranged above the processing table 1, a dual-station clamping mechanism 3 arranged inside the processing chamber 11, and a moving mechanism 5 arranged between the processing chamber 11 and the dual-station clamping mechanism 3. By setting the dual-station clamping mechanism 3 and the moving mechanism 5, the dual-station clamping mechanism 3 can clamp two workpieces to be cut at the same time. After the cutting of one workpiece is completed, the moving mechanism 5 controls the dual-station clamping mechanism 3 to move horizontally inside the processing chamber 11, so that the other workpiece can be cut. The cut workpiece is located outside the processing chamber 11, so that the operator can take out the cut workpiece and then fix the workpiece to be processed on the clamping station, thereby improving the laser cutting efficiency of the workpiece.

[0027] The laser cutting mechanism 2 includes a gantry 21, a laser cutting head 22, a first electric slide rail 23, a second electric slide rail 24, and a cylinder 25. The first electric slide rail 23 is mounted on the upper surface of the processing table 1. The gantry 21 is mounted on the slider of the first electric slide rail 23. The second electric slide rail 24 is mounted on the top wall of the gantry 21. The fixed end of the cylinder 25 is mounted on the slider of the second electric slide rail 24. The laser cutting head 22 is mounted on the piston end of the cylinder 25. During the laser cutting process of the workpiece, the first electric slide rail 23 can move the laser cutting head 22 longitudinally horizontally through the gantry 21, the second electric slide rail 24, and the cylinder 25. The second electric slide rail 24 can move the laser cutting head 22 laterally horizontally through the cylinder 25. The cylinder 25 can adjust the height distance between the laser cutting head 22 and the workpiece. This is existing technology and will not be described in detail here.

[0028] The moving mechanism 5 includes a U-shaped fixed frame 51, which passes through and is fixedly connected to the processing chamber 11. A U-shaped moving frame 52 is housed within the U-shaped fixed frame 51. A dual-station clamping mechanism 3 is disposed within the U-shaped moving frame 52. Fixed plates 53 are fixedly mounted at both ends of the lower surface of the U-shaped moving frame 52. Guide rods 54 are fixedly mounted on the side walls of the U-shaped fixed frame 51. The two fixed plates 53 and the guide rods 54 are slidably connected. The guide rods 54 guide the fixed plates 53 horizontally, ensuring their horizontal movement. By driving the fixed plates 53 to move horizontally within the U-shaped fixed frame 51, the fixed plates 53 enable the U-shaped moving frame 52 to move horizontally, thereby causing the dual-station clamping mechanism 3 to move horizontally synchronously. A guide plate 55 is fixedly mounted on the bottom wall of the U-shaped fixed frame 51. By setting a guide plate 55 with inclined surfaces on both sides, the debris generated during the laser cutting process of the workpiece can slide down to the bottom of the processing chamber 11 through the guide plate 55, avoiding accumulation on the U-shaped moving frame 52. A lead screw 56 is rotatably installed on the side wall of the U-shaped fixed frame 51. The lead screw 56 passes through two fixed plates 53 and is threadedly connected to the two fixed plates 53. By driving the lead screw 56 to rotate, the lead screw 56 can drive the fixed plates 53 to move horizontally. A second motor 57 is fixedly installed at one end of the U-shaped fixed frame 51. The drive output end of the second motor 57 is fixedly connected to one end of the lead screw 56. By turning on the second motor 57, the second motor 57 can make the lead screw 56 rotate. A support plate 58 is fixedly installed on the outer wall of the second motor 57. One end of the support plate 58 is fixedly connected to one end of the U-shaped fixed frame 51.

[0029] The dual-station clamping mechanism 3 includes two cross frame plates 31, with one end of the two cross frame plates 31 fixedly connected to each other. The two cross frame plates 31 are fixedly connected to the side wall of the U-shaped moving frame 52. Four moving plates 32 are slidably arranged in a ring array on each of the two cross frame plates 31. A clamping plate 33 is fixedly arranged on one side of the moving plate 32, and a fixed post 34 is slidably arranged on one side of the clamping plate 33. By setting four moving plates 32 and four clamping plates 33 on the cross frame plates 31, when the workpiece to be processed is placed between the four clamping plates 33, the four moving plates 32 are driven to move closer to each other, and the four moving plates 32 can make the four clamping plates 33 move closer to each other. The four clamping plates 33 can clamp and fix the workpiece through the fixed post 34.

[0030] A spring rod 35 is fixedly installed on the inner wall of the clamping plate 33. A connecting plate 36 is fixedly installed on the piston end of the spring rod 35. One side of the connecting plate 36 is fixedly connected to one end of the fixing column 34. By setting the spring rod 35 and the connecting plate 36, the fixing column 34 has a certain space for telescopic movement, so as to clamp and fix irregular workpieces.

[0031] Two protective boxes 38 are fixedly installed on the bottom wall of the U-shaped movable frame 52. A first motor 39 is fixedly installed on the bottom wall of each of the two protective boxes 38. A rotating rod 4 is fixedly installed at the drive output end of each of the two first motors 39. A first bevel gear 41 is fixedly installed at one end of each of the two rotating rods 4. Four threaded rods 42 arranged in a ring array are rotatably mounted on each of the two protective boxes 38. One of the threaded rods 42 is threadedly rotatably connected to a movable plate 32. By driving the threaded rod 42 to rotate, the threaded rod 42 can drive the movable plate 32 to move horizontally. A second bevel gear 43 is fixedly installed at one end of each threaded rod 42. A first bevel gear 41 meshes with four adjacent second bevel gears 43. By starting the first motor 39, the first motor 39 can rotate the first bevel gear 41 through the rotating rod 4. The first bevel gear 41 can rotate the four threaded rods 42 synchronously through the four second bevel gears 43, and the corresponding two threaded rods 42 rotate synchronously in opposite directions. This allows the four moving plates 32 to move closer or further apart from each other. By setting a protective box 38, the protective box 38 can protect the first bevel gear 41 and the second bevel gears 43, preventing debris from affecting the transmission of the first bevel gear 41 and the second bevel gears 43.

[0032] A cross guide shaft 37 is fixedly installed in the middle of each of the two cross frame plates 31. The four adjacent moving plates 32 are slidably connected to the cross guide shaft 37. By setting the cross guide shaft 37, the cross guide shaft 37 can guide the four moving plates 32 in the horizontal direction, so that the four moving plates 32 can maintain horizontal movement. A conical seat 44 is fixedly installed at one end of each of the two protective boxes 38. By setting the conical seat 44, the debris generated during the laser cutting of the workpiece can slide down along the inclined surface of the conical seat 44, avoiding the accumulation of debris on the top of the protective box 38.

[0033] Working principle: When laser cutting is required, in the initial state, the operator first places two workpieces between four adjacent clamping plates 33, and then turns on two first motors 39. The first motors 39 rotate the first bevel gear 41 through the rotating rod 4. The first bevel gear 41 rotates the four threaded rods 42 synchronously through the four second bevel gears 43. The four threaded rods 42 bring the four moving plates 32 closer to each other. The four moving plates 32 bring the four clamping plates 33 closer to each other. The four clamping plates 33 clamp the workpiece through the corresponding fixed posts 34.

[0034] Subsequently, through the cooperation of the first electric slide rail 23, the second electric slide rail 24 and the cylinder 25, the laser cutting head 22 is controlled to move horizontally and vertically and adjust its height to complete the cutting of a single workpiece.

[0035] After the laser cutting of a single workpiece is completed, the operator starts the second motor 57, which causes the lead screw 56 to rotate. The lead screw 56 drives the two fixed plates 53 to move horizontally. The two fixed plates 53 move the dual-station clamping mechanism 3 horizontally through the U-shaped moving frame 52, so that the laser-cut workpiece is located outside the processing chamber 11 and the workpiece to be processed is located inside the processing chamber 11. Then the operator controls the four clamping plates 33 to move away from each other, removes the processed workpiece, and clamps the workpiece to be processed between the four clamping plates 33.

[0036] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
