Automatic control equipment for online removal of tiny burrs on the working edge of the servo valve spool

Abstract

An automatic control device for online removing of tiny burrs on the working edge of a valve element of a servo valve comprises a deburring tool system, a precision feeding system, an automatic tool setting system, a force feedback system and a control system, wherein the deburring tool system mounted on a Z-axis lifting table comprises a deburring turning tool, a force sensor and a fixture, the precision feeding system used for controlling the feeding of the deburring tool system comprises an X-axis feeding mechanism, a Y-axis feeding mechanism and the Z-axis lifting table, the automatic tool setting system comprising a displacement sensor fixed on the fixture can achieve precise tool setting and complete radial runout measurement and working edge scanning detection of a workpiece, the force feedback system used for monitoring the degree of the deburring force in real time comprises a force sensor which is arranged below the deburring turning tool and connected with the fixture, and the control system used for monitoring the feeding movement, automatic tool setting, deburring, force feedback alarm retraction and online deburring effects of the automatic control device comprises an industrial personal computer connected with the precision feeding system, the force feedback system and the automatic tool setting system. The automatic control device for the online removing of the tiny burrs on the working edge of the valve element of the servo valve achieves the online automatic removing of the tiny burrs on the working edge and has the advantages of low rejection rates, high efficiency and low costs.

Description

technical field [0001] The invention relates to a process equipment for servo valve processing, in particular to an automatic control device for online removal of tiny burrs on the working edge of a valve core of a servo valve, and belongs to the technical field of mechanical manufacturing. Background technique [0002] The hydraulic servo valve is an amplifying component in the hydraulic system, which is a component that controls fluid power by mechanical movement. It converts the input mechanical signal into a hydraulic signal output, and performs power amplification. It has a simple structure and a large output power per unit volume. , Reliable work and good dynamic performance, etc., so it has been widely used in hydraulic servo systems. The spool is the central shaft part of the spool valve pair, the core component of the power amplifier stage of the servo valve. The matching accuracy between its working side and the throttle window of the valve sleeve in the axial dire...
