Pneumatic control system for clamping workpieces

Abstract

A pneumatic control system for clamping workpieces is provided. An air source is connected with a valve base plate, a first contact type two-position three-way valve and a first manual two-position three-way valve which is connected with a second contact type two-position three-way valve, a third contact type two-position three-way valve and a second manual two-position three-way valve. A first two-position five-way valve and a second two-position five-way valve are installed on the valve base plate. The first contact type two-position three-way valve is connected with a left position inlet of the first two-position five-way valve, and the second manual two-position three-way valve is connected with a left position inlet of the second two-position five-way valve. A third manual two-position three-way valve is connected between the first manual two-position three-way valve and the second contact type two-position three-way valve and connected with a right position inlet of the first two-position five-way valve and a right position inlet of the second two-position five-way valve. The first two-position five-way valve is connected with a front cavity of a first clamping air cylinder group, and the second two-position five-way valve is connected both with a rear cavity of the first clamping air cylinder group and a second first clamping air cylinder group. The pneumatic control system for clamping the workpieces is easy to operate and control, flexible and reliable.

Description

technical field [0001] The invention relates to a pneumatic control system, in particular to a pneumatic control system for workpiece clamping. Background technique [0002] At present, the workpiece clamping mechanism is often used to clamp the workpiece in the processing and manufacturing industry. The control system of the clamping mechanism includes manual control and hydraulic control. The manual control type is relatively cumbersome, low in efficiency, and the labor intensity of the operator is high; the hydraulic control type also has the following disadvantages: the liquid is basically incompressible; there is a lot of energy loss during the transmission process; it is not suitable for high or low temperature environments. Work; In order to reduce leakage, hydraulic components still require higher manufacturing precision, so the cost is more expensive, and they are more sensitive to the pollution of the working medium.
