[0002] Etched speaker mesh is a metal mesh material made by chemical corrosion etching technology. It has unique surface texture and performance characteristics. In the process of producing circular etched speaker mesh, it is necessary to use vacuum technology to coat a layer of protective film on the surface of the circular etched speaker mesh to enhance the performance and service life of the circular etched speaker mesh. Therefore, during the coating process, tooling is required to clamp and fix the circular etched speaker mesh.

[0003] At present, in the prior art, when clamping and fixing the circular etched speaker mesh, the clamping mechanism is generally adjusted sequentially to complete the clamping and fixing of the circular etched speaker mesh. However, the sequential adjustment process wastes time, resulting in low adjustment efficiency, and causes the circular etched speaker mesh to be subjected to different clamping forces. When the clamping force is too large, the circular etched speaker mesh may be damaged.

[0004] To this end, this case proposes an easy-to-adjust PVD vacuum coating tooling fixture to solve the above technical problems. Utility Model Content

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1-9 As shown, a PVD vacuum coating tooling fixture that is easy to adjust includes a base 1, square holes 2 are opened at the four corners of the top of the base 1, and the inner walls of the four square holes 2 are slidably connected to the bases 3, and the bottom ends of the four bases 3 are fixedly connected to the guide plates 4, the inner wall of the base 1 is fixedly connected to the fixed plate 5, the bottom end of the fixed plate 5 is fixedly connected to the motor 6, the driving end of the motor 6 is fixedly connected to the driving shaft 7, the top of the driving shaft 7 is fixedly connected to the rotating disk 8, and the top of the rotating disk 8 is fixedly connected to the inner gear ring 9, and the four sides of the inner wall of the base 1 corresponding to the top of the fixed plate 5 are fixedly connected to the fixed rods 10, and the four fixed rods 10 are rotatably penetrated by the transmission shafts 11, the tops of the four transmission shafts 11 are fixedly connected to the connecting rods 13, the tops of the four connecting rods 13 are fixedly connected to the guide columns 14, and the four guide columns 14 are all arranged in the guide groove at the bottom end of the guide plate 4.

[0028] In this embodiment, the bottom ends of the four transmission shafts 11 are fixedly connected to gears 12, and the four gears 12 are all meshed with the inner gear ring 9. The inner gear ring 9 drives the gears 12 to rotate synchronously, so the card holder 3 can be adjusted synchronously.

[0029] In this embodiment, the four square holes 2 are provided with a slide groove 15 at both ends, and the four sets of slide grooves 15 are connected to the limiting groove 16 at one end away from each other;

[0030] The arrangement of the sliding groove 15 and the limiting groove 16 can limit the dustproof cloth 17 during the movement of the card holder 3 .

[0031] In this embodiment, dustproof cloths 17 are fixedly connected to both ends of the four holders 3. The four sets of dustproof cloths 17 are fixedly connected to the square holes 2. The dustproof cloths 17 are made of nylon cloth, a material with excellent elasticity. Nylon cloth is lightweight and tough, combined with wear resistance and corrosion resistance, and has good elasticity.

[0032] In this embodiment, a plurality of limit blocks 18 are fixedly connected to both ends of the four groups of dustproof cloths 17. The plurality of limit blocks 18 are all arranged in the limit grooves 16. The limit blocks 18 are stuck in the limit grooves 16 and can be limited when moving.

[0033] In this embodiment, the width of the guide groove is equal to the diameter of the guide column 14, and the four holders 3 are each provided with a notch near one end, and the circular etched speaker mesh is placed in the notch, so that the circular etched speaker mesh can be clamped and moved synchronously during clamping.

[0034] It should be noted that the present invention is a PVD vacuum coating tooling fixture that is easy to adjust. When in use, the motor 6 is first started to rotate the drive shaft 7, and the drive shaft 7 rotates the rotating disk 8 and the inner gear ring 9. Therefore, the inner gear ring 9 can rotate the four gears 12 synchronously, thereby making the transmission shaft 11 and the connecting rod 13 rotate synchronously. Since the guide column 14 is in the guide groove in the guide plate 4, the guide plate 4 can be moved synchronously inward, so it can move synchronously with the holder 3, so that the circular etched speaker mesh can be clamped and fixed, thereby realizing the function of synchronous adjustment, improving the efficiency of clamping the workpiece, and the distance between the holders 3 can be adjusted, so that circular etched speaker meshes of different diameters can be clamped, thereby improving practicality.

[0035] And when the base 3 moves, the inner dustproof cloth 17 can be folded up, while the outer dustproof cloth 17 is in a stretched state, and the limit block 18 can be moved in the limit groove 16, so that the metal coating can be prevented from being adsorbed in the sliding groove during the coating process, avoiding blockage and preventing the base 3 from being unable to move.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
