Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5, An adjustable pneumatic workholding fixture, comprising a mounting plate 1 and a strip plate 2. A driver 111 is provided on the mounting plate 1. A clamping plate 113 is provided on one side of the driver 111. A base 22 is provided on one side of the strip plate 2. Square grooves 224 are formed on both the base 22 and the clamping plate 113. Second threaded holes 23 are formed through both the base 22 and the clamping plate 113. L-shaped plates 3 are provided on both the base 22 and the clamping plate 113. A rubber layer 31 is provided on the L-shaped plate 3. A strip block 311 is fixedly provided at the bottom of the L-shaped plate 3, and a clamping groove 312 is formed on the strip block 311. A second screw 231 is threadedly connected in the second threaded hole 23, and the second screw 231 is snap-fitted with the clamping groove 312.

[0024] When using the adjustable pneumatic workholding fixture, the L-shaped plate 3 can fully wrap the contact surface between the clamping plate 113 and the base 22. The square groove 224 is used to provide a fit for the strip block 311. Through the connection effect of the second threaded hole 23 and the second screw 231, the second screw 231 can penetrate through the clamping groove 312 to form a stable clamping effect on the L-shaped plate 3. The second screw 231 enables personnel to disassemble and install the L-shaped plate 3. When the clamping plate 113 clamps a workpiece, there are two sets of corresponding rubber layers 31, which can form an interlayer between the workpiece clamping surface and the clamping plate 113, avoiding abrasion of the workpiece surface caused by the metal clamping plate 113, and solving the technical problems that when the fixture clamps workpieces of different materials, the metal fixture is likely to cause abrasion to the workpiece surface and it is relatively inconvenient to replace the fixture.

[0025] Please refer to Figure 1 and Figure 2 , Mounting blocks 11 are fixedly provided on the mounting plate 1, and there are four sets of symmetrically arranged mounting blocks 11. A connection port 112 is provided on one side of the driver 111. An anti-slip layer 225 is fixedly provided on one side of the clamping plate 113. The mounting blocks 11 play a role in stably mounting the workholding fixture. By connecting a cylinder through the connection port 112, the driver 111 can form a clamping effect on the clamping plate 113. The anti-slip layer 225 is used to reduce the problem of offset and sliding after the clamping plate 113 clamps the workpiece.

[0026] Please refer to Figure 1 , Figure 3 and Figure 4 , A limiting groove 12 is formed on the mounting plate 1. A slider 223 is fixedly provided at the bottom of the base 22, and the slider 223 is movably located inside the limiting groove 12. A first threaded hole 21 is formed through one side of the strip plate 2. A first screw 211 is threadedly connected in the first threaded hole 21. Two through holes 212 are formed through the strip plate 2. A bearing 221 is provided on one side of the base 22, and the bearing 221 is connected to one end of the first screw 211. Two sliding columns 222 are fixedly provided on one side of the base 22, and the sliding columns 222 correspondingly penetrate through the inside of the through holes 212.

[0027] When using the adjustable pneumatic fixture, the strip plate 2 is provided to form the first threaded hole 21 and the through hole 212. Through the setting of the bearing 221, the effect that the first screw rod 211 rotates smoothly to drive the base 22 to move can be formed. Through the connection of the slider 223, the limiting groove 12, the through hole 212 and the sliding column 222, the limiting stability during the movement of the base 22 is achieved. When the fixture needs to be adjusted, by rotating the first screw rod 211 and through its connection with the first threaded hole 21, the movement effect of the base 22 is formed, achieving the effect of facilitating the clamping of workpieces of different sizes.

[0028] Working principle: When using the adjustable pneumatic fixture, the L-shaped plate 3 can completely wrap the contact surfaces of the clamping plate 113 and the base 22. The square groove 224 is provided to engage the strip-shaped block 311. Through the connection effect of the second threaded hole 23 and the second screw rod 231, the second screw rod 231 can penetrate the clamping groove 312 to form a stable clamping effect on the L-shaped plate 3. Through the second screw rod 231, it is convenient for personnel to disassemble and install the L-shaped plate 3. When the clamping plate 113 clamps the workpiece, there are two sets of rubber layers 31 correspondingly arranged, which can form a separation layer between the workpiece clamping surface and the clamping plate 113, avoiding the surface of the workpiece being worn by the metal clamping plate 113. It solves the technical problems that when the fixture clamps workpieces of different materials, the metal fixture is easy to grind the surface of the workpiece and it is relatively inconvenient to replace the fixture. Through the setting of the strip plate 2 to form the first threaded hole 21 and the through hole 212, through the setting of the bearing 221, the effect that the first screw rod 211 rotates smoothly to drive the base 22 to move can be formed. Through the connection of the slider 223, the limiting groove 12, the through hole 212 and the sliding column 222, the limiting stability during the movement of the base 22 is achieved. When the fixture needs to be adjusted, by rotating the first screw rod 211 and through its connection with the first threaded hole 21, the movement effect of the base 22 is formed, achieving the effect of facilitating the clamping of workpieces of different sizes.
