Electric discharge machining nozzle fixture and its operation method

Abstract

The invention discloses an electric discharge machining nozzle clamp and its operation method, comprising: a positioning device for accommodating a nozzle rod and realizing positioning and supporting of the nozzle; The locking device on the positioning device and fixes the angle of the nozzle; the positioning device has a first base structure for supporting and positioning so as to process the first blind hole in the vertical direction; the locking device has a supporting positioning for The second base structure for processing the second blind hole in the vertical direction. The EDM nozzle fixture of the present invention, according to the structural characteristics of the base structure of the positioning device and the locking device, realizes the machining of blind holes on the nozzle in the vertical direction on the EDM machine tool, and only needs one clamping to realize different axial directions. The processing of multiple blind holes improves work efficiency, reduces auxiliary processing time and processing costs, and then improves the processing quality of parts, ensures the processing size requirements of parts, and avoids the occurrence of out-of-tolerance problems.

Description

technical field [0001] The invention relates to the field of fixtures, in particular to a fixture for electric discharge machining nozzles. In addition, the present invention also relates to an operation method comprising the above electric discharge machining nozzle clamp. Background technique [0002] Due to the working process of the electric discharge machine tool, the parts can only be processed in the vertical direction. For nozzle parts, it is required to process two small holes in the same section, and the axis directions of the two small holes are different. Therefore, in the process of processing, the two small holes must be placed in the vertical direction to process. In the processing of existing parts, the first method is to design two sets of EDM fixtures, process the parts in two processes, and place the parts to be processed vertically through two different sets of fixtures. The following problems exist in the first method: (1) Due to the existence of fixt...
