Intelligent planet-tracking synchronous liquid spraying and gas absorbing device for curved surface electrolytic machining

Abstract

The invention discloses a synchronous liquid spraying and gas absorbing device. The device comprises a Z-axis servo motor, a connecting rod, an X-axis servo motor, a main valve body, a joint, a middle connecting pipe, a spray head, a flared gas scraping cover, a visual sensor, a liquid inlet pipe joint and a control system. The main valve body is in transmission connection with an output shaft of the Z-axis servo motor through the connecting rod. An output shaft of the X-axis servo motor penetrates through the main valve body to be in transmission connection with the joint. The joint is connected with the spray head through the middle connecting pipe. The visual sensor is arranged at the front end of the spray head. Vent holes are formed in the periphery of the spray head, and the flared gas scraping cover is arranged outside the vent holes. The liquid inlet pipe joint and a gas outlet pipe joint are both arranged on the main valve body. The control system is connected with the visual sensor, the Z-axis servo motor and the X-axis servo motor respectively. The device can spray liquid along with a diamond die head synchronously and absorb machining waste gas.

Description

technical field [0001] The invention relates to the technical field of green and environment-friendly electrolytic grinding, in particular to a device capable of synchronously spraying liquid and sucking air. Background technique [0002] At present, hard alloy materials are used to manufacture narrow curved surface molds, and manual grinders after EDM are generally used to drive diamond grinding heads for grinding and polishing. Due to the narrow space, the processing is difficult, and the manufacturing accuracy is low, the surface roughness value is large, and the consistency is poor. The request cannot be met. [0003] There is no cutting force in electrolytic machining, and there is no residue and deformation on the processed surface. Using the principle of electrolysis, the surface of the mold is sprayed with acid, the negative pole of the power supply is connected to the grinding head, and the positive pole is connected to the mold end. The surface of the mold is oxidi...

Problems solved by technology

[0004] Electrolytic grinding and polishing of curved surfaces has a good application prospect in mold manufacturing, but there is also a major difficulty that needs to be broken through. The electrolytic processing of cemented carbide has CO , NO 2 、H 2 Gas removal is polluting and dangerous to the environment, which has limited the application of electrolytic processing for a long time. It must be green and "zero" emission, and the exhaust gas needs to be collected effectively. The solution is to spray acid as effectively as possible to ensure the efficiency of electrolysis While reducing the amount of gas generated and synchronously tracking the absorption treatment, a virtuous cycle of reuse is formed
