Grinding wheel dresser for numerical control grinder

Abstract

A grinding wheel dresser for a numerical control grinder comprises a dressing wheel rotating mechanism and a dressing wheel feeding mechanism, wherein the dressing wheel rotating mechanism comprises a dressing wheel rotating motor and a diamond dressing wheel driven by the dressing wheel rotating motor; the diamond dressing wheel comprises a dressing wheel spindle, a flange plate and a dynamic balance adjuster; the flange plate is arranged on the dressing wheel spindle; the dynamic balance adjuster is arranged on the flange plate; and the dressing wheel feeding mechanism is divided into a dressing wheel spindle feeding part and a dressing wheel vertical feeding part. Compared with the prior art, the grinding wheel dresser for the numerical control grinder has the remarkable advantages and the beneficial effects that a numerical control mode is used for the grinding wheel dresser for the numerical control grinder, and dressing wheel spindle feeding motion and dressing wheel vertical feeding motion are controlled strictly, so that high-precision dressing to a grinding wheel is finished; the diamond dressing wheel has a dynamic balance adjusting function, and the dressing precision is improved further; and moreover, the numerical control operation mode is simple, a full-automatic dressing mode is adopted, requirements to operators are low, and the grinding wheel dresser for the numerical control grinder is convenient to use.

Description

technical field [0001] The invention relates to a numerical control device used for dressing the grinding wheel of a grinding machine, and is especially suitable for processing high-precision precision tool equipment. Background technique [0002] At present, there are generally two methods of dressing for drill grinders and grinding wheels in the domestic tool industry: diamond pen dressing and mechanical non-NC dressing. The diamond pen trimming method has the disadvantage that the diamond tip will gradually become blunt during use, thereby greatly reducing the machining accuracy; while the mechanical non-NC trimming method has higher precision, but lower production efficiency. [0003] On the other hand, with the advancement of technology, the requirements for various sectional shapes and compensation of grinding wheels are getting higher and higher, especially for precise dressing of the grinding wheel section and pressure angle, diamond pen dressing and mechanical non-N...
