Multi-axis Micro-hole EDM Vibration Machining Device

Abstract

The invention relates to a multi-axis micro-hole electric spark vibration machining device, which comprises a lifting unit, a beam, a multi-axis machining unit, a workbench, a base and a cross slide. The lifting unit is fixed on the base through a column, and the beam and the lifting unit The connecting plate in the unit is fixedly connected, the multi-axis machining unit is fixedly connected with the beam through the motor bracket, the cross slide is arranged on the base and is located below the multi-axis machining unit, and the worktable is arranged on the cross slide. The invention provides a multi-axis micro-hole EDM vibration machining device. By setting up a plurality of tool electrodes to process a plurality of micro-holes on a workpiece synchronously, and the electrodes do not interfere with each other, independent machining can be realized, which is beneficial to To improve the processing efficiency, an electromagnetic vibrator is installed at the bottom of the feeding table, and the electromagnetic vibrator can remove the chips and electro-erosion particles generated after the electrode is machined in time, which not only ensures the normal operation of the tool electrode, but also improves the performance of the micro-hole. Machining accuracy and quality.

Description

technical field [0001] The invention belongs to the technical field of electric discharge machining, and particularly relates to a multi-axis micro-hole electric spark vibration machining device. Background technique [0002] Nowadays, many mechanical products are designed with tiny holes, such as engine blades, cylinder heat dissipation holes, valve body air passage holes or oil passage holes, etc. Because the fine deep holes that need to be processed usually have high hardness and high strength, and most of them are difficult-to-machine materials, such as stainless steel, heat-resistant steel, diamond and cemented carbide. What's more, due to the limitation of use occasions, the micro-holes are mostly large in radius and depth, which makes the processing of micro-deep holes become the most difficult kind of hole processing technology. At present, traditional single-electrode EDM devices are mostly used on the market to process fine and deep holes, but the processing effic...

Problems solved by technology

What's more, due to the limitation of the application occasion, the semi-depth diameter of the micro-hole is relatively large, which makes the processing of the micro-deep hole become the most difficult one in the hole processing process.

At present, traditional single-electrode EDM devices are mostly used in the market to process micro-deep holes, but the processing efficiency is very low, and the depth of the processed holes is limited.
