Problems solved by technology

[0004] Although this motor-driven jaw movement method is simple in structure and easy to control, its clamping force is uncontrollable, and the clamping force provided for different sizes and different stiffnesses to be clamped is constant. The condition of the clamping piece adjusts the clamping force. Therefore, for the piece to be clamped with less rigidity, there may be a situation where the piece to be clamped is collapsed, and for the heavy weight and larger size to be clamped parts, the clamping force provided may not be enough, so that the clamping may be unstable or even fall during the transfer or processing, which may cause processing safety accidents

Abstract

The invention discloses a workpiece clamping method using a differential pressure type pneumatic clamp, and relates to the field of pneumatic clamps. According to the scheme, a workpiece is clamped with a differential pressure type pneumatic clamp. The differential pressure type pneumatic clamp comprises a clamp body, a first clamping jaw, a second clamping jaw, a rack and pinion drive assembly and a differential pressure pneumatic telescopic cylinder. The differential pressure type pneumatic telescopic cylinder can be adjusted in output force, then the differential pressure type pneumatic clamp can be adjusted in clamping force, different clamping force can be used for clamping to-be-clamped parts with different rigidity, the situation that flattening is caused due to excessive clamping force or tight clamping cannot be realized due to too small clamping force is reduced, the clamping stability and reliability are improved, and the applicability is high.

Description

technical field [0001] The invention relates to the field of pneumatic clamps, in particular to a workpiece clamping method using differential pressure pneumatic clamps. Background technique [0002] In the field of machining, there are all kinds of clamping tools, and pneumatic clamps are one of them. [0003] In the field of laser cutting, chucks and manipulators are common clamping tools. Take the manipulator as an example. Among the existing published patents, the Chinese patent application with the application number "201910864876.3" discloses the "manipulator", which includes the upper fixture. 5.9 and the lower fixture 5.8, the upper fixture 5.9 and the lower fixture 5.8 all include clamping blocks and clamping racks, the upper fixture 5.9 and the lower fixture 5.8 are arranged oppositely, and the clamping gear is driven to rotate by the clamping motor, and then the clamping gear drives the clamp The tightening rack moves, thereby driving the upper clamp and the lowe...
