Embodiment 1
[0035] like figure 1 , 2 , 3, 4, 5, 6, 7, 8, the hollow tool electrode 7 with a diameter of 1 mm is clamped and fixed on the rotating shaft 5 by the collet 6, and the working fluid supply pipe is connected to the housing 13 at the same time At the liquid injection port, the pressure of the liquid supply overflow valve is adjusted to 0.5-1MPa, and the automatic adjustment end face sealing device 11 plays a role in sealing and maintaining pressure. It forms a boundary effect with the discs 2 and 3 to make it rotate at a high speed, driving the rotating shaft 5 to rotate at a high speed, and the high-speed rotating shaft 5 drives the tool electrode 7 held by the lower end to rotate at a high speed, and then connects the electric screw 12 to conduct electricity, and uses the working fluid to conduct electricity The conductivity passes through the rotating shaft 5, so that the current is conducted to the high-speed rotating tool electrode 7, and the working fluid is ejected from t...

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 tool electrode high-speed rotating electrical processing equipment driven by a Tesla turbine. Background technique [0002] During electrical machining, the high-speed rotation of the tool electrode is beneficial to improve the processing conditions. At present, the 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 conduct electricity when the tool electrode rotates at a high speed for electrical machining. There are two ways of electric conduction: ① carbon brush electric conduction; ② mercury electric lead. Due to the high-speed rotation when carbon brushes are used for electric conduction, the electric contact position wears quickly and needs to be replaced in a short period of time, resulting in low processing efficiency. Using the mercury conduction method will bring harm...
