A hydraulic oil supply system for torsion shaft dedendum rolling enhanced machine tool

Abstract

The invention provides a hydraulic oil supply system for a rolling strengthening machine tool for a tooth root of a torsion shaft. The hydraulic oil supply system comprises a control unit, a motor pump assembly, an air cooler, a temperature transmitter, a heater, a check valve, a pressure sensor, an air filter, a coarse filter, a fine filter, a stop valve, an energy accumulator, an electric-hydraulic proportional pressure relief overflow valve, a pressure gauge, a pressure relay, a reversing valve, a digital display meter, a liquid level relay, a hydraulic chuck, an oil tank and the like. According to the hydraulic oil supply system provided by the invention, a pressure of oil output by a hydraulic station is accurately controlled through the electric-hydraulic proportional pressure reliefoverflow valve, the change of the pressure can be adapted in a large range, and an overflow function is achieved, so that the safe working of the hydraulic station is ensured; the electric-hydraulicproportional pressure relief overflow valve is adopted, and is not inferior to servo pressure adjustment in accuracy, and low in cost, so that requirement on the cleanliness of the oil is reduced; andin addition, the energy accumulator is used for maintaining the pressure, so that lots of heat generated due to pump running is reduced to a great extent, and energy conservation is realized.

Description

technical field [0001] The invention belongs to the field of hydraulic technology, and in particular relates to a hydraulic oil supply system for a torque shaft dedendum rolling enhanced machine tool. Background technique [0002] As an important component of the vehicle suspension system, the torsion shaft needs to be strengthened on its surface and tooth root before use. The rolling machine tool is the equipment for strengthening its processing, and the hydraulic system that controls its rolling pressure is an important part of it. . At present, the main hydraulic systems mainly include the following types: [0003] (1) Three-stage hydraulic system is adopted, the rolling pressure changes in steps, automatic positioning, enhanced rolling and smooth rolling to achieve the improvement of rolling quality and straightening. [0004] (2) The rolling pressure is adjusted by electro-hydraulic servo control, and the precise adjustment of the rolling pressure is realized. The wo...
