A high-precision rotatable electric spark perforator

Abstract

The invention introduces a high-precision rotatable electric spark perforator, including a main machine and an electric control box, the electric control box is electrically connected with the main machine, and the electric control box is used to control the work of the main machine; the main machine includes a base, a rotating lifting mechanism and a machine head , the height and rotation angle of the machine head are controlled by the rotating lifting mechanism; the electrical control box includes the box shell, the box frame, the middle partition, the bottom plate, the accessory box and the handle, and the accessory box is located in the lower half of the inner space of the control box. It is used to load the disassembled parts of the electric spark piercer. The electric spark piercer not only has the advantages of low cost, small size, light weight, simple operation and portability, but also the design of its electrical control box is easy for daily inspection and maintenance; the supporting parts have fixed positions and packaging containers, It is convenient to set a clear and clear installation sequence, and can avoid bumping, damage and loss of the electric spark piercer during transportation.

Description

technical field [0001] The invention relates to the field of machining, in particular to a high-precision rotatable electric spark punching machine. Background technique [0002] Existing EDM machines are mainly used for processing holes and cavities in mold production and removing metal residues such as screws, knives, taps, drills, plug gauges and other metal residues that remain in parts due to improper processing. A kind of mechanical processing equipment, its working principle is to use the electrode installed on the machine head to contact the parts immersed in the working fluid or the metal tools that need to be corroded (corroded) to form a small discharge gap (0.01 -0.05mm); after electrification, when the pulse voltage is applied between the two poles, the discharge is instantaneous, resulting in a high concentration of energy (10-107W / mm), and the instantaneous high temperature generated in the discharge area is enough to melt, corrode or even evaporate the metal;...

Problems solved by technology

[0003] But existing electric discharge machine has the following problems: 1, existing electric discharge machine mostly is to take the structural form of equipment base, plane guide rail, workbench, column, machine head, electrical control cabinet, working liquid water tank, so electric discharge machine The production of the spark machine is difficult, the manufacturing cost is high, and the volume is large, the quality is heavy, and the price is expensive; 2. The existing EDM machine is complicated to operate, and it cannot be operated without professional training and learning; 3. 1. The EDM machines used in enterprises generally use kerosene or special EDM engine oil as the working fluid. Since kerosene is flammable and explosive, it is a dangerous product. If it is used and kept improperly in production, it will cause production accidents, which will bring great harm to the enterprise and Employees bring life and property hazards, and the special EDM engine oil is the product of hydrogenation of kerosene components, which is a secondary hydrogenation product. Both kerosene and special EDM engine oil will produce toxic fumes and odors during the processing process. Stimulate the skin, eyes and nervous system, cause harm to the human body, and the discarded working fluid will pollute the environment; 4. When the EDM machine is working, it moves in a straight line, and the machine head can only process parts vertically. If you want to achieve angled processing, you can only use complex auxiliary fixtures, which have great limitations and often cannot meet the processing needs; 5. The high power consumption of the existing EDM machine increases the processing cost ; 6. The existing EDM machine has a limited working area and cannot process large parts or parts with processing dead ends; 7. The existing EDM electrical control cabinet has many electrical components and complex structure; The work can not effectively dissipate heat and cool down, and it is easy to cause the burning of the circuit and the damage of the electrical parts. Once a failure occurs, the repair and daily inspection and maintenance are extremely inconvenient; 8. The existing EDM machine has a complex structure and many parts. The container packaging is fixed and formed, so the parts are bumped, damaged and missing during transportation, which brings economic losses to both the supply and demand sides
