A Liquid Injection and Drainage Online Dynamic Balancing Head Structure for High Rotational Speeds

Abstract

The invention discloses a liquid injection and draining type on-line dynamic balance head structure for high rotation speed conditions. The liquid injection and draining type on-line dynamic balance head structure comprises a chassis and a water channel cover; the side face of the chassis is provided with a first through hole and a plurality of liquid storage cavities, the liquid storage cavities are evenly distributed in the periphery of the first through hole, and a plurality of annular grooves which are parallel are formed in the inner wall of the first through hole in the circumferential direction; liquid inlet holes communicated with the corresponding liquid storage cavities are formed in the bottoms of the annular grooves; the outer side of the chassis is provided with a plurality of second through holes communicated with corresponding liquid storage cavities respectively, and throttle valves are arranged in the second through holes respectively; and the water channel cover is fixed to the lateral face of the chassis. By means of the liquid injection and draining type on-line dynamic balance head structure, on-line dynamic balance of a grinding wheel can be rapidly and continuously achieved, stopping for liquid removing is not needed, and the current does not need to be led in.

Description

technical field [0001] The invention belongs to the field of dynamic balance, and relates to a liquid injection and discharge type online dynamic balance head structure used in the case of high rotating speed. Background technique [0002] In recent years, major industrial countries have successively invested a lot of manpower, material resources and financial resources to research and promote high-speed grinding technology. The high-speed grinding technology is a qualitative change in the grinding process, the grinding efficiency and the machining accuracy of the parts are significantly improved, and it is easier to realize automatic grinding. Especially in recent years, the demand for processing brittle and hard materials such as ceramics, optical glass, and single crystal silicon has greatly promoted the research and promotion of high-speed grinding technology. As a key component of a grinding machine, the grinding wheel directly affects the machining process capability ...

Problems solved by technology

However, the structure of this device can only inject liquid but not discharge liquid, so that it cannot have a continuous balance ability. When the liquid storage chamber is full of liquid, it must be stopped to clean up the liquid, so that the balance head can continue to work. At the same time, the traditional process also uses a solenoid valve. To realize the outflow of liquid, but in the process of controlling the solenoid valve, it is necessary to introduce current, so that the current is easily introduced into the balance head, the safety is poor, and the cost is high
