[0002] From a processing principle perspective, engraving is a machining process that combines drilling and milling. It is widely used for processing products such as two-color boards, architectural models, small signs, and three-dimensional crafts. A digital control system controls the engraving machine to process the workpiece, thereby achieving the desired product functionality.

[0003] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: the fixture cannot effectively fix some uneven or irregular surfaces, and the product may deviate during processing and engraving, resulting in product scrap or quality problems, which wastes a lot of time and energy of the staff; therefore, in order to solve the above problems, an anti-deformation fixture for laser engraving is proposed. Utility Model Content

Therefore, this utility model proposes an anti-deformation fixture for laser engraving.

[0008] The effect achieved by the above components is that, through the cooperation of the translation slot translation block and the moving block, it can prevent the situation where the left and right movement cannot be well clamped when the moving block is sliding.

[0009] Preferably, a spring is fixedly connected to the inner wall of the sliding groove, and the other end of the spring is fixedly connected to the sliding block.

[0010] The effect achieved by the above components is that, through the cooperation of the spring sliding groove and the sliding block, the sliding block can be returned to its original position by the elastic force of the spring itself when not clamped.

[0011] Preferably, a handle is fixedly connected to the surface of the circular block, and the size of the sliding block is adapted to the size of the sliding groove.

[0028] Reference Figure 1As shown, this utility model provides a technical solution: a laser engraving anti-deformation clamp, including a fixed plate 1, a clamping device 2 on the surface of the fixed plate 1, and an auxiliary device 3 on the surface of the moving block 204. By setting the clamping device 2, the user can clamp the item, avoiding the problem that traditional laser engraving clamps cannot effectively fix uneven or irregular surfaces, which may cause the product to deviate during engraving, resulting in product scrap or quality problems, wasting a lot of time and energy for the staff. The auxiliary device 3 can help fix irregular products, such as products that are too long or have a small bottom and a large top. For products with high appearance requirements, the staff can replace the rubber pad 33 for auxiliary fixation, improving production efficiency and the practicality of the device.

[0029] The specific configuration and function of its clamping device 2 and auxiliary device 3 will be described in detail below.

[0030] Reference Figure 2 and Figure 3 As shown in this embodiment: the clamping device 2 includes two mounting plates 201, which are fixedly connected to the surface of the fixed plate 1. A screw 202 is threadedly inserted into the surface of the mounting plate 201. A round block 203 is fixedly connected to one end of the screw 202, and a moving block 204 is fixedly connected to the other end of the screw 202. The moving block 204 slides on the surface of the fixed plate 1. Two sliding grooves 205 are formed on the surface of each moving block 204. A sliding block 206 is slidably connected to the inner wall of the sliding groove 205. A translation groove 207 is formed on the surface of the fixed plate 1. A translation block 208 is slidably connected to the inner wall of the translation groove 207. The translation block 208 is fixedly connected to the moving block 204, and the translation block 208 is connected to the translation groove 207. The dimensions of the sliding groove 205 are matched with those of the sliding block 206. The other end of the spring 209 is fixedly connected to the sliding block 206. The surface of the round block 203 is fixedly connected to the handle 210. The dimensions of the sliding block 206 are matched with those of the sliding groove 205. Through the cooperation of the translation groove 207, the translation block 208 and the moving block 204, the situation where the left and right movement cannot be well clamped when the moving block 204 is sliding can be prevented. Through the cooperation of the spring 209, the sliding groove 205 and the sliding block 206, the sliding block 206 can be returned to the original position due to the elasticity of the spring 209 when not clamped. Through the cooperation of the handle 210 and the round block 203, the operator can easily rotate the screw 202.

[0031] Reference Figure 4 and Figure 5As shown, specifically, the auxiliary device 3 includes a rectangular plate 31, which is fixedly connected to the surface of the movable block 204. A groove is formed on the surface of the rectangular plate 31, and a convex plate 32 is slidably connected to the inner wall of the groove. A rubber pad 33 is fixedly connected to the surface of the convex plate 32. A fixing rod 34 is fixedly connected to the surface of the rectangular plate 31, and a rotating plate 35 is rotatably connected to the arc surface of the fixing rod 34. An elliptical block 36 is fixedly connected to one end of the fixing rod 34, and the rotating plate 35... The surface of the rotating plate 35 has a movable hole, and an irregularly shaped rod 37 is slidably connected to the inner wall of the movable hole. Two L-shaped plates 38 are fixedly connected to the surface of the rectangular plate 31. The L-shaped plates 38 are adapted to the convex plate 32. A torsion spring 39 is sleeved on the arc surface of the fixing rod 34. The two ends of the torsion spring 39 are fixedly connected to the elliptical block 36 and the rotating plate 35, respectively. Through the cooperation of the two L-shaped plates 38 and the rectangular plate 31, the convex plate 32 can be quickly positioned and installed. Through the cooperation of the two L-shaped plates 38 and the rectangular plate 31, the convex plate 32 can be quickly positioned and installed. Through the cooperation of the torsion spring 39 and the rotating plate 35 and the elliptical block 36, when the rotating plate 35 is opened, the rotating plate 35 will automatically return to its original position due to the torsion of the torsion spring 39 itself.

[0032] Working principle: When the operator needs to clamp the product, the operator turns the handle 210, which drives the circular block 203 to rotate. The circular block 203 drives the screw 202 to rotate. The screw 202 rotates within the mounting plate 201, which drives the moving block 204 to slide. The moving block 204 drives the translation block 208 to move. The translation block 208 slides on the inner wall of the translation groove 207. The moving block 204 drives the spring 209 on the inner wall of the sliding groove 205 to move. The spring 209 drives the sliding block 206 to move. When the sliding block 206 touches the product, it causes the spring 209 to contract, thus completing the clamping.

[0033] When the user needs to install the convex plate 32, the user rotates the rotating plate 35. The rotation of the rotating plate 35 causes the torsion spring 39 to retract. At the same time, the moving hole of the rotating plate 35 moves away from the irregular rod 37, and the convex plate 32 is placed on the plane of the L-shaped plate 38. The user pushes the convex plate 32 to slide on the plane of the L-shaped plate 38 and slides into the groove of the rectangular plate 31. The user releases the rotating plate 35, and the torsion force of the torsion spring 39 causes the rotating plate 35 to return to the original position and be inserted into the irregular rod 37, thus completing the installation.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
