Description

High-precision diamond roller profile detection device Technical Field The invention relates to the technical field of diamond roller detection, in particular to a high-precision diamond roller profile detection device. Background The diamond roller profile detection is a key link for ensuring the performance of the diamond roller profile detection as a high-precision grinding wheel dressing tool. The diamond roller has complex molded surface and high precision requirement (generally needs to be controlled at micron level), and the traditional detection mainly depends on an indirect replication method, and has the problems of low efficiency, error accumulation and the like. 1. Transfer replication (copy) is the dominant method specified in industry standards such as JB/T10040. The principle is that a diamond roller is used for trimming a grinding wheel, then the grinding wheel is used for grinding a test piece (such as a steel bar or a graphite sheet), and finally the roller precision is reversely pushed by measuring the profile of the test piece. The method has the defects of complicated flow, multiple clamping and grinding wheel abrasion, easiness in introducing accumulated errors and incapability of realizing real-time detection. 2. Off-line contact measurement, the wheels are measured directly using a three-Coordinate Measuring Machine (CMM) or profiler. Because the surface of the diamond roller is fully covered with hard particles, the direct contact measurement can easily cause abrasion or sinking of the probe into a particle gap, and the precision and the service life of the probe are affected. The probe is adopted for measurement, firstly, the measurement is two-dimensional, the profile on one section can be obtained only by one scanning, the complex three-dimensional profile characteristics of the roller are difficult to comprehensively reflect, secondly, the speed is low, contact abrasion exists, the scanning path needs to be planned, the efficiency is low, and micrometer-level abrasion risks exist on the surfaces of the probe and the roller, so that the probe is not suitable for frequent measurement. 3. And (3) optical projection comparison, namely placing the roller or the test piece under a projector to compare with a standard template. The method is visual but has limited precision, has insufficient detection capability on complex three-dimensional molded surfaces, is easily influenced by reflection and the like of the diamond surface in simple optical detection, and has low detection precision. For this reason, a high-precision diamond roller profile detection device is needed.
