In order to enable the workpiece to be replaced quickly and thus improve the processing efficiency, a bracket 8 is welded on the top of the fixed seat 7, and three clamping grooves 9 are provided at both ends of the bracket 8, and a reset spring 10 is installed at one end of the inner side of the clamping groove 9, and a clamping frame 11 is slidably embedded at one end of the reset spring 10 on the inner side of the clamping groove 9. In order to speed up the clamping and removal of the workpiece, one end of the three clamping frames 11 is welded through the bracket, and both sides of the bottom end of the processing table 1 are welded It is connected to a vertical transmission rail 12, and a transmission screw 13 and a guide slide bar 14 are rotatably connected to the inner sides of the two vertical transmission rails 12 respectively. A vertical transmission motor 15 is installed on one side of the bottom end of the processing table 1 through the base, and the transmission end of the vertical transmission motor 15 is connected to one end of the transmission screw 13. In order to realize the vertical adjustment of the cutting mechanism, a support frame 16 is sleeved on the outer sides of the transmission screw 13 and the guide slide bar 14 on the inner sides of the two vertical transmission rails 12, and a transverse sliding warehouse 17 is welded in the middle of the top of the support frame 16. A transverse transmission cylinder 18 is installed at one end of the inner side of the transverse sliding warehouse 17 through the base. In order to realize the transverse adjustment of the cutting mechanism, an extended end of the transverse transmission cylinder 18 is slidably embedded in an extension frame 19 inside the transverse sliding warehouse 17, and a downward pressure cylinder 20 is installed on the top inner side of the extension frame 19 through the base. The extended end of the downward pressure cylinder 20 is slidably embedded in a laser cutting machine 21 at the bottom end of the extension frame 19, and the extended end of the downward pressure cylinder 20 is connected to the top of the laser cutting machine 21.

[0023] Working principle: First, the operator installs the workpieces on the inner side of the workpiece clamping mechanism at the feeding end of the conveying mechanism in sequence, and then the operator starts the conveying motor 2, and drives the conveying mechanism to convey through the conveying motor 2, so as to successively move the clamping mechanisms that do not clamp the workpieces. During this period, the conveying motor 2 will drive a double-layer pulley 4 connected to its transmission end to rotate, and the double-layer pulley 4 will drive the other connected double-layer pulleys 4 to rotate through the belt 5. At the same time, several double-layer pulleys 4 will drive several transmission shafts 3 welded thereto to rotate, and then the transmission shaft 3 will drive the conveyor belt 6 sleeved on its outer side to transmit, and the transmission conveyor belt 6 will drive the fixed seat 7 fixed on its outer side by bolts to move, and during the clamping period, the operator pulls a clamping frame 11, and then one end of the clamping frame 11 will pull the reset spring 10 to slide outward inside the clamping slot 9 opened at one end of the bracket 8, and after the distance between the two clamping frames 11 is greater than the width of the workpiece, the operator places the workpiece on the top of the fixed seat 7;

[0024] Then release the clamping frame 11, and the reset spring 10 will pull the clamping frame 11 to reset inside the clamping slot 9, and clamp and fix the workpiece, so as to continue to fix the workpiece. As the conveying mechanism continues to convey, the clamping mechanism carrying the workpiece will be conveyed to the bottom end of the cutting mechanism. After the workpiece is conveyed to the bottom end of the cutting mechanism, the operator stops the conveying motor 2, and then starts the transverse transmission cylinder 18 at the transverse coordinates of the cutting position on the surface of the workpiece as needed. At that time, the transverse transmission cylinder 18 will push the cutting mechanism to move laterally inside the transverse sliding bin 17. After reaching the specified position, the operator stops the transverse transmission cylinder 18, and then starts the vertical conveying motor 15. At that time, the vertical conveying motor 15 will drive the transmission screw 13 connected to its transmission end to move The driving screw 13 will drive the support frame 16 to move through the threaded sleeve on its outer side, so as to adjust the vertical position of the cutting mechanism. After the position is determined, the operator starts the pressing cylinder 20 and starts the laser cutting machine 21 at the same time. At that time, the laser cutting machine 21 will be pressed down to the surface of the workpiece, and then the vertical transmission motor 15 and the pressing cylinder 20 will be started at the same time according to the shape to be cut, so as to control the movement of the cutting mechanism, so as to realize the cutting of the workpiece surface. After the workpiece cutting is completed, the transmission mechanism will be started again. As the first cut workpiece is transmitted to the feeding end of the transmission mechanism again, the operator takes out the workpiece after cutting and puts in the new workpiece, so as to repeat the cycle. Such a design can improve the efficiency of workpiece processing.

[0025] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
