Digital detection system based on diamond roller dressing grinding machine

Abstract

The invention discloses a digital detection system based on a diamond roller dressing grinding machine, and relates to the field of computer numerical control (CNC) grinding machines. The invention aims to solve the problem that the dressing time of a grinding wheel is hard to control and the automatic dressing can not be achieved. The digital detection system is technically characterized in thatthe overall surface roughness of the grinding wheel is observed through a CCD camera, and the surface residual stress, degree of passivation and degree of thermal damage of the grinding wheel and a diamond roller are monitored by a digital sensor, transmitted to a control terminal, and compared with the preset target grinding data stored in a database; a first executive component and a second executive component are controlled to act by judgment of the results, so that the ratio of the relative grinding speed to the tangential feed rate is decided, till the real-time grinding data and the target grinding data are matched finally; and thus, the degree of automation in the grinding process of the grinding machine and the working efficiency are improved, and the qualification rate of productsis ensured.

Description

technical field [0001] The invention relates to the field of numerical control grinding machines, in particular to a digital detection system based on diamond roller dressing grinding machines. Background technique [0002] The most widely used dressing method for grinder wheels is the single-grain diamond pen dressing method, but this dressing method can only trim a single straight line profile. When it is necessary to dress the surface with a complex profile, the more advanced diamond roller dressing method is often used . At present, the existing forming grinding process is to control the running route of the dresser tool through the two-axis linkage and relying on the numerical control method, so as to carry out the forming and dressing of the grinding wheel. It has good dressing effect on complex forming surfaces, long service life and durability. and wide application range. [0003] Existing publication number is that the Chinese patent of CN104942716A discloses a ki...

Problems solved by technology

[0004] However, in order to grasp the timing of grinding wheel dressing, static detection methods are generally used, such as the rolling copy method and the stylus method in the prior art. These methods are offline and post-event detection, so it is not conducive to improving work efficiency and ensuring product qualification rate, cannot achieve trimming automation
