Abstract

The invention relates to the electric spark punching field, and discloses a water pressure nozzle-converging chuck which comprises a piston and a piston cylinder sleeve, the piston cylinder sleeve is externally covered closely on the outer edge of the piston, the water-compressing nozzle-converging chuck also comprises a connector, an elastic converging nozzle and a converging nozzle sleeve through high pressure water, the piston base of the piston is connected with the connector, an oil cylinder structure is formed by the connector, the piston and the piston cylinder sleeve, the elastic converging nozzle comprises a converging nozzle base and is connected on the head part of a piston rod of the piston through the converging nozzle base which is provided with a plurality of elastic converging nozzle petals, a cone with a through-hole in the center is formed by the plurality of the converging nozzle petals, a converging nozzle is externally covered on the outer edge of the elastic converging nozzle and is closely matched with the elastic converging nozzle. The invention utilizes a high pressure water to clamp a copper tube, can be used conveniently, and has no adverse effect on the processing quality and the copper tube.

Description

technical field [0001] The invention relates to the field of electric spark perforation, in particular to a water compression nozzle chuck. Background technique [0002] At present, EDM piercers generally use copper tubes as pulse electrodes, and liquid (mostly water) as pulse medium. In the actual processing process, chucks are often used to clamp the copper tubes. At present, there are generally two types of copper pipe chucks suitable for EDM piercing machines, namely small drill chucks and spiral chucks. These two chucks have certain defects: the installation and use are more complicated, and improper clamping actions often occur. Conditions that affect the processing quality and even cause damage to the copper tube. Contents of the invention [0003] The purpose of the present invention is to provide a water compression nozzle chuck, which uses high-pressure water to clamp the copper pipe, which is very convenient to use and will not have adverse effects on the proce...
