A tool system for online removal of tiny burrs on the working edge of a servo valve spool

Abstract

Disclosed is a tool system for online removal of tiny burrs on a servo valve element working edge. The tool system comprises a turning tool, a cantilever type force sensor, a clamp, an adjusting block and a bridge connection plate. The bridge connection plate is connected and installed on a motion control device. The clamp is connected with the bridge connection plate through the adjusting block. A groove is formed in the adjusting block. The clamp can move up and down along the groove so as to adjust the height of the clamp. One end of the cantilever type force sensor is provided with the turning tool, and the other end of the cantilever type force sensor is connected with the clamp. The turning tool comprises a base body and a blade, wherein the base body is a 40 Cr+ molybdenum block, the blade is made of artificial monocrystal diamond, the front angle of the turning tool is 3 degrees, the back angle of the turning tool is 6 degrees, the roughness of the front tool face and the back tool face is 0.01 micrometer, the radius of the edge opening of the cutting edge is smaller than 100 nanometers, the edge width is 4 millimeters, and the edge opening is sharp without tipping under the observation of a 1000-time magnifier. According to the tool system for online removal of the tiny burrs on the servo valve element working edge, the burrs on the valve element workpiece working edge can be effectively removed in an online mode, the precision of the working edge is ensured, the part rejection rate is reduced, meanwhile, production efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to a process equipment for servo valve processing, in particular to a tool system for online removal of tiny burrs on the working edge of a servo valve core, belonging to the technical field of mechanical manufacturing. Background technique [0002] The valve core is the core component of the power amplifier stage of the servo valve, the center shaft part of the slide valve pair, and the processing quality of the working side, especially the control of the tiny burrs, has an important impact on the performance of the matching movement flexibility and the amount of overlapping of the pair. . In the production process, the final processing process of the working edge adopts the method of grinding by precision grinding machine. The method of removing the tiny burrs generated during the processing is to install it offline on the deburring device after processing, and at the same time use the ground hard alloy strip and wrap it with T...

Problems solved by technology

[0004] However, the size of the burrs that need to be removed in the deburring tools in the existing patents is relatively large, and the burrs generated during the grinding process of the servo valve core are of micron scale, so the machining accuracy is very high. , the existing deburring tools are difficult to meet the processing requirements
