Problems solved by technology

[0002] At present, since the stator forming and pressing for motor vehicles adopts manual pressure regulation, after measuring the size of the stator to meet the specified requirements, it is considered that the stator pressing is successful, so the efficiency is low, mainly because the precision is not high, and it is difficult to control accurately manually, and the requirements for operators Relatively high, the waste has been high, so the cost is high and the failure rate is also high

Abstract

The invention discloses a stator numerical control dead-slow pressurizing hydraulic control system for a motor car. A dead-slow pressurizing system is composed of a two-position four-way solenoid valve, a two-way flow precise control valve and a check valve. A rapid pressurizing system is composed of a directional plug-in, a directional control cover plate and a two-position three-way electromagnetic ball valve. A digital display pressure gage and a precise pressure sensor are arranged on a pipeline communicated with a rodless cavity of an oil cylinder, and a pressure accurate control loop is further connected with pipeline in parallel. The pressure accurate control loop is composed of a two-position two-way ball valve and a proportional servo pressure valve. The stator numerical control dead-slow pressurizing hydraulic control system for the motor car has the beneficial effects that pressure accurate control of equipment is ensured; automatic timekeeping and pressure maintaining are achieved; after the stator numerical control dead-slow pressurizing hydraulic control system is applied, the equipment operation is reliable, the adjustment is visual, simple and convenient, and the pressure error is small.

Description

technical field [0001] The invention belongs to a hydraulic control system, and relates to a stator numerical control micro-speed pressurization hydraulic control system for a motor vehicle. Background technique [0002] At present, since the stator forming and pressing for motor vehicles adopts manual pressure regulation, after measuring the size of the stator to meet the specified requirements, it is considered that the stator pressing is successful, so the efficiency is low, mainly because the precision is not high, and it is difficult to control accurately manually, and the requirements for operators Relatively high, the waste has been high, so the cost is high, and the failure rate is also high. How to achieve precise pressure control is an urgent problem to be solved at this stage. Contents of the invention [0003] The purpose of the present invention is to provide a numerical control micro-speed pressurization hydraulic control system for the stator of the motor c...
