[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 - 4 , the present invention discloses a mesh plate positioning tooling, including a workbench 10. A pair of first round holes 20 are opened on the top surface of the workbench 10. Two elastic clamping mechanisms 30 are provided at the bottom end of the workbench 10. A mesh plate positioning plate 40 is placed in the middle of the top surface of the workbench 10. The mesh plate positioning plate 40 is clamped on the two elastic clamping mechanisms 30. A pair of vertical plates 50 are fixedly connected to the top surface of the workbench 10. Electric cylinders 60 are bolted on one side of the two vertical plates 50 close to each other. Fastening mechanisms 70 are provided at the output ends of the bottom ends of the two electric cylinders 60.

[0023] Specifically, the elastic clamping mechanism 30 includes a long plate 31. Two springs 32 are welded on the top surface of the long plate 31. The top ends of the two springs 32 are welded on the bottom surface of the workbench 10. A clamping post 33 is welded in the middle of the top surface of the long plate 31. The clamping post 33 penetrates through the first round hole 20.

[0024] In this embodiment, normally, the protruding length of the clamping post 33 is relatively long, and clamping can be achieved. When being squeezed, it can elastically contract and will not affect the up and down movement of the fastening mechanism 70.

[0025] Specifically, the fastening mechanism 70 includes a mounting base 71. A motor 72 is bolted to the top surface of the mounting base 71. A U-shaped plate 73 is bolted to the top surface of the mounting base 71. The output end of the electric cylinder 60 is bolted to the top surface of the U-shaped plate 73. The bottom end of the mounting base 71 is rotatably connected to a rotating plate 74. The bottom output end of the motor 72 is fixedly connected to the top surface of the rotating plate 74. A slot 75 is formed in the side wall of the rotating plate 74. A fastening component 76 is inserted into the slot 75. A second round hole 77 is formed in the bottom surface of the rotating plate 74. An arc-shaped sliding groove 80 is formed in the top surface of the rotating plate 74. An annular sliding strip 90 is welded to the bottom end of the mounting base 71. The arc-shaped sliding groove 80 is slidably connected to the annular sliding strip 90. The fastening component 76 includes a pressing plate 761. A plug strip 762 is integrally connected to the side end of the pressing plate 761. A third round hole 763 is formed in the top surface of the plug strip 762.

[0026] In this embodiment, it can be used in cooperation with the electric cylinder 49 to realize the extrusion and locking of the mesh plate. During the extrusion of the mesh plate, the mesh plate positioning plate 40 is also extruded. The mesh plate positioning plate 40 does not need to be fixedly installed with bolts. At the same time, the fastening component 76 can be replaced and can be replaced according to the specifications of the mesh plate, so as to facilitate the fixation of mesh plates of different specifications.

[0027] Specifically, the mesh plate positioning plate 40 includes a positioning template 41. Extension plates 42 are integrally connected to both sides of the positioning template 41. Fourth round holes 43 are formed in the top surfaces of the extension plates 42.

[0028] In this embodiment, the mesh plate can be positioned, so that the position of the mesh plate processed each time can be kept consistent, and the processing quality is guaranteed.

[0029] Specifically, the first round hole 20, the second round hole 77, the third round hole 763 and the fourth round hole 43 are coaxial. The clamping post 33 passes through the first round hole 20, the second round hole 77, the third round hole 763 and the fourth round hole 43.

[0030] In this embodiment, the positioning and clamping of the mesh plate positioning plate 40 can be realized through a clamping post 33, and the locking of the fastening mechanism 70 can also be realized, and it will not interfere with the subsequent swinging and up-and-down movement of the fastening mechanism 70.

[0031] Working principle and usage process of the present utility model: Select a screen positioning plate 40 that matches the screen to be processed, place the screen positioning plate 40 on the workbench 10, and make the clamping post 33 pass through the fourth round hole 43. Insert the fastening assembly 76 that matches the screen into the slot 75, and start the electric cylinder 60 to extend. At this time, the clamping post 33 passes through the second round hole 77 and the third round hole 763, and the locking of the fastening assembly 76 can be achieved. During normal use, the retraction displacement of the electric cylinder 60 is half of the maximum displacement. At this time, the clamping post 33 always passes through the second round hole 77 and the third round hole 763. When positioning and fixing the screen, first place the screen on the positioning template 41, and then start the electric cylinder 60 to extend. At this time, the fastening assembly 76 moves downward and presses above the screen, and the locking of the screen and the screen positioning plate 40 can be achieved. At the same time, the elastically protruding clamping post 33 moves downward elastically, and the spring 32 is elastically stretched. At this time, the clamping post 33 still passes through the second round hole 77 and the third round hole 763.
