Problems solved by technology

When the existing fixture clamps the workpiece, it usually takes the two parallel surfaces of the workpiece as the reference plane, and then clamps it through the tightening device on the fixture; when the material of the workpiece is soft, the user must clamp it when clamping. Reasonably control the clamping force. If the clamping force is too small, it will cause the workpiece to be clamped loosely, and the workpiece will move during processing; if the clamping force is too large, it will cause the workpiece to be squeezed and deformed; and now Some fixtures do not have a device that can detect the clamping force, and the user also manually measures when clamping, so the error of clamping is large, which is not conducive to improving the clamping accuracy of the workpiece; at the same time, the workpiece should be clamped during the clamping process. The force is stable, and the user will have errors in the control of the clamping force during manual clamping, which will also cause damage to the workpiece
In addition, when processing a large number of workpieces, the user needs to repeat the process of clamping and dismounting. The process is cumbersome, and the user also needs to spend more time adjusting the clamping force, which is not conducive to improving the processing efficiency.

Abstract

The invention provides an anti-deformation auto-protecting pneumatic bench vice. The anti-deformation auto-protecting pneumatic bench vice includes a fixed vice jaw module, and a sliding slot is formed in the side, directly facing a movable vice jaw module, of the fixed jaw module. The sliding slot is internally and slidably provided with a push plate, a piezoelectric material is disposed on the front end surface of the push plate, and a telescopic rod is vertically fixed to the rear end surface of the push plate. A telescopic hole is formed in the rear end surface of the sliding slot, a solenoid valve is disposed at the rear end of the telescopic hole in a sealed mode, and the solenoid valve is connected with the piezoelectric material through a wire. A piston is disposed at the rear endof the telescopic rod, and the piston is slidably disposed in the telescopic hole. According to the anti-deformation auto-protecting pneumatic bench vice, the change of the clamping force received bya workpiece during the tightening is automatically detected through the adjustment of the air pressure; and when excessive tightening occurs, the workpiece is automatically released to be protected, the clamping and correcting time of the workpiece is shortened, and the clamping efficiency is improved.

Description

technical field [0001] The invention relates to the field of clamps, in particular to a pneumatic clamp. Background technique [0002] Fixture refers to the device used to fix the processing object in the process of mechanical manufacturing so that it can occupy the correct position to accept construction or inspection, also known as fixture. Fixtures are usually composed of positioning elements, clamping devices, tool setting guide elements, indexing devices, connecting elements, and clamp bodies. When the existing fixture clamps the workpiece, it usually takes the two parallel surfaces of the workpiece as the reference plane, and then clamps it through the tightening device on the fixture; when the material of the workpiece is soft, the user must clamp it when clamping. Reasonably control the clamping force. If the clamping force is too small, it will cause the workpiece to be clamped loosely, and the workpiece will move during processing; if the clamping force is too lar...
