Grinding internal cooling system capable of automatically calibrating liquid supply position

Abstract

The invention discloses a grinding internal cooling system capable of automatically calibrating the liquid supply position. The system comprises a grinding wheel device and a liquid supply position automatic calibrating mechanism. The grinding wheel device comprises an internal-cooling grinding wheel, a liquid guide gate, a flange plate and a second nut. The liquid guide gate penetrates through a center hole of the internal-cooling grinding wheel; the second nut and the flange plate clamp the liquid guide gate and the internal-cooling grinding wheel to form the grinding wheel device; and the grinding wheel device is mounted on a grinding machine spindle through a first nut. The liquid supply position automatic calibrating mechanism comprises a joint, a motor, an adjusting sleeve and a gear. When the rotating speed of the grinding wheel changes, the motor can drive the adjusting sleeve to rotate by a proper angle through the gear according to a feedback signal of a grinding machine control system, so that when grinding liquid flows through a rectangular opening of the adjusting sleeve, elliptical holes of the liquid guide gate and small radial holes of the internal-cooling grinding wheel and then reaches the working face of the grinding wheel, the grinding liquid is exactly injected into a grinding area, and automatic calibration of the liquid supply position is achieved. The grinding internal cooling system capable of automatically calibrating the liquid supply position has the characteristics that the utilization ratio of the grinding liquid is increased, the grinding quality is improved, the cost is reduced, and the environment is protected.

Description

technical field [0001] The invention belongs to the field of grinding processing, in particular to an internal cooling system for grinding processing which can automatically calibrate the liquid supply position. Background technique [0002] Grinding has the advantages of high machining accuracy, good surface quality and wide application range. However, grinding also has problems such as high grinding specific energy and low processing efficiency, and most of the mechanical energy is converted into heat energy and accumulates in the grinding area, resulting in high grinding temperature, which affects the surface quality of the workpiece and aggravates the wear of the grinding wheel ; and most of the grinding debris generated during the grinding process are bonded on the surface of the grinding wheel and the workpiece in an orderly manner. As the grinding process continues, they enter the grinding area and squeeze each other with the workpiece and the grinding wheel, further ...

AI Technical Summary

Problems solved by technology

Some scholars have added pressurized equipment on this basis to increase the cooling and lubrication effects of this method, but its biggest shortcoming is that it has not solved the problem that the grinding fluid will splash around with the rotation of the grinding wheel.

[0007] In summary, the current grinding cooling system needs to be further improved
