Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and in the form of embodiments.

[0025] Such as Figure 1-Figure 2 As shown, a dual-purpose spindle in an EDM machine tool includes a spindle system, namely the Z system, and a linear motor system, namely the W system;

[0026] The spindle system is set on the column 1 of the EDM machine tool, including the Z-axis servo motor 2, the ball screw 5, the Z-axis slide seat 6 and the R-axis 9, and the Z-axis servo motor 2 is fixed on the column 1 through the motor bearing seat 3. Specifically, the Z-axis servo motor 2 is fixed on the motor bearing seat 3 through bolts, and the Z-axis servo motor 2 is connected with the Z-axis ball screw 5 through a coupling. The Z-axis servo motor 2 drives the Z-axis ball screw 5 to rotate so as to drive the Z-axis sliding seat 6 to move up and down, and the R-axis 9 is fixed on the R-axis bracket fixedly connected to the lower part...

Abstract

The invention discloses a dual-purpose main shaft in an Electric Discharge Machining machine tool. The dual-purpose main shaft is characterized by comprising a main shaft system and a linear motor system, wherein the main shaft system is arranged on a stand column of the Electric Discharge Machining machine tool and involves a Z-axis servo motor, a ball screw, a Z-axis sliding seat and an R shaft,the linear motor system involves a linear motor and an electrode wire clamping mechanism, an electric motor is connected with the electrode wire clamping mechanism, a motor stator is fixed on a mounting plate, and the mounting plate is fixedly mounted on the Z-axis sliding seat. According to the dual-purpose main shaft in the Electric Discharge Machining machine tool, under the condition that a common Electric Discharge Machining main machine structure is not changed, the linear motor is combined to the servo motor drive, and the transformation cost is small, the machining requirements of a large-depth-diameter-ratio micro-hole, a narrow slit and a narrow groove can be met, the large-weight and large-area electrode machining task requirements can be met.

Description

technical field [0001] The invention belongs to the field of electric machining technology, relates to an electric discharge machine tool, and in particular provides a dual-purpose spindle in the electric discharge machine tool. Background technique [0002] With the development of high-tech industries such as aerospace and automotive energy, the requirements for EDM technology are getting higher and higher. The spindle part of the EDM machine tool is one of its key components, and its power consumption accounts for about 60%-80% of the total power of the machine tool. The performance of the spindle part directly affects the processing efficiency, processing quality, and processing accuracy of the machine tool. In EDM, although there are cases of using horizontal servo machining or linkage interpolation to process complex profiles, most of the cases are Z-axis servo feed, horizontal X, Y-axis positioning, and translation. Therefore, the performance of the spindle can be use...
