Multi-axis micro-hole electric spark vibration machining device

Abstract

The invention relates to a multi-axis micro-hole electric spark vibration machining device. The device comprises a lifting unit, a cross beam, a multi-axis machining unit, a workbench, a base and a cross sliding table, wherein the lifting unit is fixedly arranged on the base through a stand column, the cross beam is fixedly connected with a connecting plate in the lifting unit, and the multi-axis machining unit is fixedly connected with the cross beam through a motor support; and the cross sliding table is arranged on the base and located below the multi-axis machining unit, and the workbench is arranged on the cross sliding table. According to the multi-axis micro-hole electric spark vibration machining device, a plurality of tool electrodes are arranged to synchronously machine a plurality of micro-holes in a workpiece, the electrodes do not interfere with one another, independent machining can be achieved, the machining efficiency can be improved, meanwhile, an electromagnetic vibrator is arranged at the bottom of a material containing table, and the electromagnetic vibrator can timely remove cuttings and electric corrosion particles generated after the electrodes a reused for machining the holes, so that not only is the normal operation of the tool electrodes ensured, but also the machining precision and quality of the micro-holes are improved.

Description

technical field [0001] The invention belongs to the technical field of electrical discharge machining, and in particular relates to a multi-axis micro-hole electrical discharge vibration machining device. Background technique [0002] Nowadays, many mechanical products are designed with microscopic holes, such as engine blades, cooling holes in the cylinder body, air or oil holes in the valve body, etc. Because the micro 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 the application occasion, the semi-depth diameter of the micro-hole is relatively large, which makes the processing of the micro-deep hole 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 th...

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.
