Abstract

The invention discloses a stator numerical control micro-speed pressurization hydraulic control system for a motor vehicle. A two-position four-way solenoid valve, a two-way flow precision control valve and a one-way valve form a micro-speed pressurization system; a direction plug-in, a direction control cover plate and a two-position three-way The rapid pressurization system is formed by the electromagnetic ball valve; the pipeline connected with the rodless chamber of the oil cylinder is equipped with a digital display pressure gauge, a precision pressure sensor, and a precise pressure control circuit in parallel, which consists of a two-position two-way ball valve and a proportional servo pressure valve. composition. Beneficial effects: ensure accurate control of equipment pressure, realize automatic timing and pressure maintenance, and after application, the equipment operates reliably, and the adjustment is intuitive and simple, 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...
