Embodiment 1

[0035] Such as figure 1 , 2 , 3, 4, 5, 6, 7, and 8, the hollow tool electrode 7 with a diameter of 1mm is clamped and fixed on the rotating shaft 5 by the collet 6 while the working fluid supply tube is connected to the housing 13 Liquid injection port, the pressure of the liquid supply overflow valve is adjusted to 0.5-1MPa, and the end face sealing device 11 is automatically adjusted to seal and maintain the pressure. At this time, the working fluid in the housing 13 is opened through the disc 1 2 and the driving disc 2 3 When drilling, the working fluid forms a boundary effect with the disc one 2 and the driving disc two 3 to make it rotate at a high speed, driving the rotating shaft 5 to rotate at high speed, and the high-speed rotating shaft 5 drives the tool electrode 7 clamped at the lower end to rotate at a high speed. The electric screw 12 leads electricity, and uses the conductivity of the working fluid to pass through the rotating shaft 5 to conduct the current to the...

Abstract

The invention belongs to the technical field of electromachining and provides high-speed rotation tool electrode electromachining equipment driven by a Tesla turbine. The high-speed rotation tool electrode electromachining equipment comprises an end cover, a shell, a driving disc, a rotary shaft, an electric-induced screw, an automatic end face adjusting sealing device, a high-speed bearing, a collet chuck, a key, a gasket, an elastic check ring and a tool electrode. The driving disc is connected with the rotary shaft through the key and provides driving force for high-speed rotation of the tool electrode. The electric-induced screw is fixed to the shell. Currents are transferred to a working electrode through working liquid in the shell and the rotary shaft. By means of the automatic adjusting sealing device, the effect that the device is reliably sealed when the rotary shaft rotates is guaranteed. By the adoption of the high-speed rotation tool electrode electromachining equipment, high-speed rotation of the tool electrode can be achieved, and reliable electric induction can be achieved during high-speed rotation. The high-speed rotation tool electrode electromachining equipment can be used in the electromachining fields such as electrochemical machining, electrosparking machining and electrochemical discharge machining.

Description

Technical field [0001] The invention relates to the field of electrical processing equipment, in particular to a high-speed rotating electrical processing equipment for tool electrodes driven by a Tesla turbine. Background technique [0002] During electrical machining, high-speed rotation of the tool electrode is beneficial to improve the processing conditions. The current high-speed rotation of the tool electrode basically uses a high-speed motor to drive the tool electrode to rotate, but it is difficult to induce electricity when the tool electrode is rotated at high speed for electrical machining. There are two ways to draw electricity: ① carbon brush draw electricity; ② mercury draw electricity. When the carbon brush is used to draw electricity, due to the effect of high-speed rotation, the contact position of the electricity draw is quickly worn and replaced in a short time, resulting in low processing efficiency. Using mercury to draw electricity will cause harm to the op...
