Abrasion test bench

Abstract

The invention relates to an abrasion test bench, which comprises a frame, a linear reciprocating motion mechanism, a guide seat, a guide rod, an abrasion rock sample seat, an abrasion rod, an abrasion rotation power system and a force sensor, the front end and the rear end of the guide rod are mounted on the frame, and the guide seat sleeves the guide rod and is in front-back sliding connection with the guide rod; the linear reciprocating motion mechanism and the abrasion rotating power system are both installed on the frame and arranged in a vertically spaced mode, the movable end of the linear reciprocating motion mechanism and the abrasion rock sample base are both connected with the guide base and located on the rear side of the guide base, and one end of the abrasion rod is installed at the power output end of the abrasion rotating power system. And the force sensor is arranged between the guide seat and the movable end of the linear reciprocating motion mechanism. By the adoption of the test bed, simulation of the abrasion life of the cutting pick can be achieved, reference can be provided for optimizing motion parameters in actual cutting with the purpose of reducing abrasion of the cutting pick as the purpose, and the test bed is compact in structure and small in investment.

Description

technical field [0001] The invention relates to a test bench for abrasion test for the purpose of studying the abrasiveness problem in the rock cutting process. Background technique [0002] A prominent problem when cutting hard materials such as rocks is abrasiveness. Under the action of large cutting force, the picks will wear out quickly and fail. The existing standard abrasion test bench uses a needle-shaped thin rod to rub and slide against the rock sample under a small positive pressure. The parameters such as normal pressure and relative sliding speed are customized according to the unified standard. The abrasiveness is artificially graded and evaluated, and then the abrasive grade of the rock is obtained, which does not involve the wear life simulation of the pick. Contents of the invention [0003] The invention aims to provide an abrasion test bench, which can not only realize the simulation of the wear life of the pick, but also provide reference for optimizing...
