Quality Detection Technology Of Brake Cylinder’s Compensation Hole Inner Surface Research

Measuring system for compensating hole of brake master cylinder is mainly to measure the place, dimension and figure of the compensated hole and at the same time to measure the quality of machining and foundry by image for inner exterior of brake master cylinder. The measuring system adopt high differentiate rate image technigue of CCD and using high precision’s drive framework to finish the measure assignment.lt has some virtues, such as easy to handle, precision is high, degree of automatization is high, dependability is high, and eliminate the influence of subjective complication. It is high-powered exactitude measuring system which gathered optics, mechanics, eletronics and computer language.The measuring system for compensating hole of brake master cylinder is made up of computer data acquire and process system, control system, CCD system, optical grating bit shift sensor and micro-machine drive system.The whole system adopts human-computer interactive measurement, when the cylinder was retracting, we can install the workpiece to be measure to orientation fixture.
