Electric spark electrode clamp and using method

Abstract

The invention belongs to the technical field of machining, and relates to an electric spark electrode clamp and a using method thereof. The electric spark electrode clamp comprises an electrode chuck and an electrode connector arranged under the electrode chuck; a height adjusting mechanism is arranged on the electrode chuck; the height adjusting mechanism is connected with the electrode connector, and the height adjusting mechanism adjusts the longitudinal distance between the electrode chuck and the electrode connector; a rotating mechanism is arranged between the electrode chuck and the electrode connector; the rotating mechanism drives the electrode connector to rotate by 360 degrees around the longitudinal axis of the electrode chuck, and the front-back distance and the left-right distance between the electrode chuck and the electrode connector are adjusted. The device is simple in structure, small in size, stable and reliable in clamping, convenient and fast in electrode replacement, low in frequency and high in working efficiency, and the electrode can be rapidly clamped, disassembled, aligned and cut.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to an electric spark electrode fixture and a use method, in particular to a quick-change fixture for clamping, aligning and cutting an electric spark electrode and a use method. Background technique [0002] Due to the special structure and function of precision coupler valve bushing, the valve or bushing often has various asymmetric functional hole structures. The processing method of this structure generally can only rely on EDM machine tools. The electrodes are processed. Before each processing, the electrodes are clamped on the electrode clamping head that comes with the machine tool, and the X, Y, and Z directions of the electrodes are aligned.

Problems solved by technology

[0002] Due to the special structure and function of precision coupler valve bushing, the valve or bushing often has various asymmetric functional hole structures. The processing method of this structure generally can only rely on EDM machine tools. The electrodes are processed. Before each processing, the electrodes are clamped on the electrode clamping head that comes with the machine tool, and the X, Y, and Z directions of the electrodes are aligned. During actual processing operations, the electrodes will be worn for a period of time, whether it is To replace a new electrode or to cut a worn electrode, the electrode must be disassembled; and after the replacement or cutting is completed, the electrode needs to complete the clamping and alignment steps again; however, due to the electrode clamping head of the existing machine tool , there are problems of complex structure, large size and bulky, complex steps of clamping, disassembling and aligning electrodes, resulting in low work efficiency, and the existing electrode clamping head cannot cut and trim electrodes, increasing the number of electrode replacements, and the operation is cumbersome. Extended machining time for valve or bushing parts
