Controllable and high-precision experimental device for researching grinding mechanism

Abstract

The invention relates to a controllable and high-precision experimental device for researching a grinding mechanism. The experimental device is characterized in that structures on a base body are distributed in a manner of forming a 120-degree mutual difference; an upper T-shaped slide block and a lower T-shaped slide block are relatively arranged in a slide groove of the base body; a diamond tool is in precise clearance fit with the lower T-shaped slide block; a round-mouth clamp is arranged on the base body and is adjacent to the upper T-shaped slide block; an axial spiral micrometer dial (with the resolution ratio of 1 micron) is arranged above the upper T-shaped slide block and is matched with the round-mouth clamp; three radial spiral micrometer dials (with the resolution ratio of 10 microns) are distributed on the base body in the manner of forming the 120-degree mutual difference. A new thought for researching the grinding mechanism is proposed by a single abrasive particle, double abrasive particles and multiple abrasive particles in an all-directional manner based on controllable and high-precision properties of the device; the device is particularly used for researching an influence rule on a surface forming mechanism and a material removing mechanism by different axial distances and radial distances between the adjacent abrasive particles. The controllable and high-precision experimental device for researching the grinding mechanism is simple in structure, convenient to operate, strong in practicability and high in testing precision, and a researching method is novel and unique.
