Portable high-precision rotatable spark erosion perforating machine

Abstract

The invention discloses a portable high-precision rotatable spark erosion perforating machine. The portable high-precision rotatable spark erosion perforating machine comprises a main machine and an electric control box. The electric control box is electrically connected with the main machine and is used for controlling the main machine to work. The main machine comprises a base, a rotary lifting mechanism and a machine head. The height and the rotary angle of the machine head are controlled through the rotary lifting mechanism. The electric control box comprises a box body outer shell, a box frame, a middle partition plate, a bottom plate, an accessory box and a lifting handle. The accessory box is arranged on the lower half portion of the internal space of the control box and is used for loading all parts of the spark erosion perforating machine after the spark erosion perforating machine is disassembled. The spark erosion perforating machine has the advantages of being low in cost, small in size, light in weight, easy to operate and easy to carry, and the daily inspection and maintenance are easy due to the design of the electric control box. Matching parts and components are provided with fixed positions and packaging containers, so that clear installation orders are easy to arrange, and collision, damage and loss of the spark erosion perforating machine in the transportation process can be avoided.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a portable high-precision rotatable electric spark perforator. 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 evapo...

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
