[0002] An engraving machine is a machine used to perform precise engraving on various materials such as wood, metal, plastic, etc. It can engrave complex patterns and texts by controlling the motion trajectory of the engraving head.

[0003] When using an engraving machine, the workpiece to be engraved must first be secured to the machine's baseplate. For example, a cylindrical workpiece is typically secured using a V-shaped clamp. The engraving machine can then be started to perform the engraving operation. However, existing clamping tools can only hold a single workpiece. Each engraving operation requires removing the completed workpiece and securing the next workpiece to be engraved. This operation is cumbersome when engraving the same batch of workpieces, and it also affects engraving efficiency. To address this issue, we propose a clamping device for an engraving machine.

[0030] See also Figure 4 In the figure, the wall surface of the clamping plate 20 away from the slide rod 17 is fixedly connected with a rubber pad 21; specifically, the rubber pad 21 can increase the friction with the workpiece to be engraved, so that the workpiece to be engraved clamped between the V-shaped plate 8 and the clamping plate 20 has a good anti-slip effect.

[0031] Working principle: First, the workpieces to be engraved are placed on the base plate 3 in turn, and each workpiece to be engraved is located between the adjacent V-shaped plate 1 8 and V-shaped plate 2 16, then the turntable 25 is rotated, the turntable 25 will drive the stud 11 to rotate on the two U-shaped seats 10, the stud 11 will drive the U-shaped plate 12 to slide forward on the outer wall of the stud 11, the U-shaped plate 12 will drive the connecting plate 5 to slide forward on the upper end of the base plate 3 (in this process, the U-shaped plate 12 will also slide forward in the rectangular groove 22 on the base plate 3), the connecting plate 5 will drive the square frame 6 and the multiple long plates 14 on the square frame 6 to slide forward together on the base plate 3 (in this process, the two T-shaped blocks 23 on the square frame 6 will slide forward in the T-shaped grooves 24 on their respective corresponding base plates 3), the square frame 6 and the multiple long plates 14 on the frame 6 will drive a group of connecting columns 15 on each of them to move forward together, and each connecting column 15 will drive the V-shaped plate 2 16 on each of them to move forward together.

[0032] Taking one of the V-shaped plates 16 as an example, the V-shaped plate 16 will slide forward in the sliding groove 9 on the corresponding V-shaped plate 1 8, and the forward movement of the V-shaped plate 16 will drive the two elastically connected plywood 20 on it to move forward together, and the rubber pads 21 on the two plywood 20 will contact the workpiece to be engraved. As the V-shaped plate 16 continues to move forward, the four sliding rods 17 between the plywood 20 and the V-shaped plate 16 will all move backward relative to the V-shaped plate 16 (in this process, the circular plates 18 on each of the four sliding rods 17 will leave the V-shaped plate 16, and the four springs 19 between the two plywood 20 and the V-shaped plate 16 will be squeezed on the outer walls of the corresponding sliding rods 17), and the workpiece to be engraved can be tightly clamped between the corresponding V-shaped plate 8 and the two plywood 20. Similarly, other workpieces to be engraved will be tightly clamped between their respective corresponding V-shaped plates 8 and the two clamping plates 20 (it should be noted that even if there are small differences and errors in the diameters of some workpieces, each workpiece can be ensured to be clamped under the action of the spring 19). At this time, the turntable 25 can be stopped and the next engraving operation can be carried out (the working principle of the engraving machine is a well-known existing technology and will not be repeated). When the engraving is completed, the turntable 25 can be rotated in the opposite direction to remove the multiple workpieces to be engraved from the base plate 3 and between their respective corresponding V-shaped plates 8 and the two clamping plates 20. The operation is simple.

[0033] It should be noted that this clamping device can clamp multiple workpieces at the same time, with good clamping effect, and the clamping and removal of the workpieces are simple, which not only brings convenience to the staff, but also helps to improve the engraving efficiency.
