Abstract
The invention discloses a grinding head used for electrolytic grinding. The grinding head used for electrolytic grinding comprises a cylindrical grinding head body with an inner cavity, grinding strips, lifting pins, a left end cap, a right end cap and a clamping handle; clamping grooves and liquid outlet holes are formed in the cylindrical surface of the grinding head body, the clamping grooves are square grooves in the spiral direction and formed in the cylindrical surface of the grinding head body at equal internals, and the grinding strips and the clamping grooves are detachably arranged in a matched mode; and the liquid outlet holes are formed between the two clamping grooves at equal internals. When the grinding head body works, an electrolytic solution is supplied to machining gaps directly through the interior of the grinding head body, electrolytic solution supply is sufficient and in time, products are not prone to accumulation, and the phenomenon that the short circuit burn is caused by the unsmooth electrolytic solution supply or untimely product discharging is reduced. Owing to the fact that the adopted grinding strips can be replaced, adaptation is better, and application cost is lower.

Preferably, grinding head body, ejector pin, clamping handle are the product being made up of the metal material of acid-alkali-corrosive-resisting.
Operation principle involved in the present invention is as follows.
Clamping handle is rotated in the presence of actuating device, by central through hole on clamping handle to grinding head body feed flow,
Fixing groove on the end cap of left and right is designed for being ground bar radial positioning, and the effect of the spinning in and out of ejector pin is grinding bar
It is pressed in draw-in groove.
During work, by directly providing electrolyte to processing gap inside grinding head body, feed flow is fully timely, and product is difficult product
Tired, smooth or product is not discharged to the short circuit burn phenomenon for causing not in time to reduce feed flow.During grinding head body rotation, on the one hand it is electrolysed
Product can wash away and be ground under the dual function of bar tangential velocity in electrolyte and be excluded, on the other hand, equally spaced liquid outlet
Setting ensure that the uniformity in flow field, further increase surface quality.
Advantages of the present invention is as follows：
1. short circuit burn phenomenon is less, and the course of processing is more stable, and grinding tool working life is longer.The present invention is internal straight by grinding head body
Connect to processing gap and electrolyte be provided, feed flow is fully timely, product is difficult accumulation, reduce feed flow not smooth or product be discharged to too late
When and cause short circuit burn phenomenon.
2. changeable type is designed, better adaptability, and application cost is lower.The detachable grinding bar of present invention design, one
Denier is ground bar wear out failure, can achieve fast quick-detach and replacing, and can adopt grinding bar of different nature to meet different processing
Need.Additionally, the grinding machine head body of the present invention is reusable, integrated cost is low.
