[0031] like Figure 1-4The pneumatic tooling of a power box cover shown in the figure includes a base 100, a cylinder 200, a support column 300 and a pressure rod 400; a fixed plate 101 is provided on the base 100, and the fixed plate 101 is located at the edge of one side of the top surface of the base 100; the cylinder 200 is arranged on the other side of the top surface of the base 100; the support column 300 is arranged on the base 100, and the support column 300 and the cylinder 200 are arranged side by side; one end of the pressure rod 400 is connected to the piston rod of the cylinder 200, the middle part of the pressure rod 400 is rotatably connected to the support column 300, and the other end of the pressure rod 400 is located directly above the fixed plate 101. Specifically, the cylinder 200 is fixedly connected to the base 100 by bolts, and the piston rod of the cylinder 200 is located in the vertical direction. A connecting hole is provided at the end of the pressure rod 400, and the piston rod is connected to the pressure rod 400 through the connecting hole. The support column 300 and the fixed plate 101 are also fixed to the base 100 by bolts, and the bolts on the fixed plate 101 are embedded to avoid the bolts from affecting the materials fastened on the fixed plate 101, which is beneficial to improving the overall stability of the tooling.

[0032] The beneficial effect of the present invention is that the tooling utilizes the lever principle so that when the piston rod of the cylinder 200 rises, one end of the pressure rod 400 is driven to rise and the other end is driven to fall, thereby realizing the pressing effect of the pressure rod 400 on the material, greatly improving the clamping speed of the material, and the material is fixed to the side of the tooling, reducing the area occupied by the material on the tooling, and avoiding contact between the tooling and the surface to be processed of the material, which brings great convenience to the processing of the staff, and at the same time improves the production safety factor, avoiding accidents caused by the operator's hand being pressed by the cylinder 200 due to operational errors.

[0033] Please refer to Figure 2 In one possible embodiment, a pressing block 401 is provided at the other end of the pressing rod 400, and the pressing block 401 is located above the fixed plate 101. It is easy to understand that the provision of the pressing block 401 can increase the contact area between the tooling and the material, thereby improving the stability of the tooling in clamping the material.

[0034] Please refer to Figure 3 In one possible embodiment, the other end of the pressure rod 400 is bent downward to form a bent portion 402. The pressure block 401 is provided with a through hole and a stop pin 403. The bent portion 402 extends into the through hole, and the stop pin 403 is passed through the bent portion 402. It is easy to understand that the pressure block 401 is fixed to the pressure rod 401 by the stop pin 403. When the pressure block 401 wears out and needs to be removed, it can be easily removed by simply pulling out the stop pin 403.

[0035] Please refer to Figure 4In one possible embodiment, a first limiting groove 102 is provided on the top of the fixing plate 101. The first limiting groove 102 is used to limit the material. It should be noted that when clamping materials with this fixture, simply place the material in the first limiting groove 102, then activate the cylinder 200 to press the pressure block 401 downward to secure the material. The first limiting groove 102 prevents the material from accidentally sliding horizontally, thereby improving the stability of the fixture in securing the material.

[0036] Please refer to Figure 3 In one possible embodiment, a rotating shaft 301 is provided at the top of the support column 300, and a rotating hole 404 is provided in the middle of the pressure rod 400, into which the rotating shaft 301 extends. It is easy to understand that by providing the rotating shaft 301 at the top of the support column 300 and passing through the rotating hole 404 located in the middle of the pressure rod 400, the pressure rod 400 is rotatably connected to the support column 300, thereby making the support column 300 serve as a fulcrum for the pressure rod 400, and thus allowing the pressure plate to compress or loosen the material using the principle of leverage under the drive of the cylinder 200.

[0037] Please refer to Figure 3 In one possible embodiment, a second limiting groove 302 is provided at the top of the support column 300, and the rotating shaft 301 is disposed in the second limiting groove 302. A fastener 303 is also provided at the top of the support column 300, and the fastener 303 interferes with the rotating shaft 301. It should be noted that the second limiting groove 302 can provide a mounting base for the rotating shaft 301 and limit the rotating shaft 301 to prevent it from accidentally moving. The fastener 303 can fix the rotating shaft 301 to prevent it from accidentally rotating. This design can facilitate the separation of the pressure rod 400 from the support column 300. When the pressure rod 400 needs to be disassembled, the staff only needs to unscrew the fastener 303 to remove the pressure rod 400 and the rotating shaft 301, and can easily pull the rotating shaft 301 out of the rotating hole 404.

[0038] Please refer to Figure 4 In one possible embodiment, the base 100 includes a panel 103 and support legs 104. The cylinder 200 and support column 300 are disposed at the upper end of the panel 103, and the support legs 104 are disposed at the lower end of the panel 103. It is easy to understand that there are multiple support legs 104, and the multiple support legs 104 are evenly spaced along the length of the panel 103. The support legs 104 are arranged to ensure that the panel 103 is at a certain height from the bottom surface, so that the material can be suspended in the air after being fixed to the panel 103, providing convenience for the operator.

[0039] Please refer to Figure 1In one possible embodiment, there are multiple cylinders 200, support columns 300, and pressure rods 400, and the multiple cylinders 200, support columns 300, and pressure rods 400 are evenly spaced along the length of the base 100. It should be noted that one cylinder 200, one support column 300, and one pressure rod 400 together form a compression assembly, and one compression assembly is used to compress a part of the material. By providing multiple compression assemblies to compress different parts of the material, the tooling's tightness on the material is improved.

[0040] Please refer to Figure 5 The clamping process of this tooling is briefly described as follows: taking the power box cover as an example, the cylinder 200 drives the piston rod to descend, and the piston rod drives one end of the pressure rod 400 to descend and the other end to rise, and drives the pressure block 401 to rise. The operator puts the side wall of the power box cover into the first limiting groove 102, and then makes the cylinder 200 drive the piston rod to rise, and the piston rod drives one end of the pressure rod 400 to rise and the other end to descend, and drives the pressure block 401 to descend, so that the pressure block 401 conflicts with the power box cover. The power box cover is fixed to the side of the tooling under the clamping of the fixing plate 101 and the pressure block 401, which greatly improves the clamping and disassembly speed of the power box cover. Moreover, on the whole, the power box cover is suspended on the tooling, which also provides great convenience for the processing of the power box cover.

[0041] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
