Embodiment Construction

[0025] (1) Matching research of slider 9 and guide rail 5

[0026] First grind the two concave V-shaped surfaces of the guide rail 5 and the two convex V-shaped surfaces of the slide block 9 . Through mutual matching research, it is ensured that the flatness error of the four planes is less than 1 μm and more than 80% of the areas are in contact with each other.

[0027] Then grind the installation reference surface of the guide rail 5 to ensure that the parallelism error between the intersection line of the two concave V-shaped surfaces of the guide rail 5 and the installation reference surface is less than 1 μm. The standard mandrel can be used for detection during measurement; put the standard measuring mandrel into the V-groove of the guide rail 5, measure the height difference between the highest points at both ends of the mandrel relative to the installation datum plane of the guide rail 5, and grind the installation datum of the guide rail 5 Surface to reduce this diff...

Abstract

The invention belongs to the technical field of precise machining, and provides a high-precision diamond pen grinding wheel finisher and an adjustment method. The finisher comprises a diamond pen, a diamond pen base, a locking nut, a dustproof cover, a guide rail, a slide block, a guide rail soft belt, a pressing plate, a finisher shell, a copper nut, a motor connecting plate and a screw motor. The V-shaped slide block and the guide rail precisely matched are adopted for plastic bonding and precise scraping treatment to obtain higher linear motion precision; a form of monorail is adopted; the finishing and measuring precision of the device is basically not influenced by tiny rotation in the moving direction of the slide block; the dynamic and static friction coefficients of the guide rail soft belt and steel are lower are more approximate to effectively reduce the creeping phenomenon in the moving process of the slide block; in addition, the guide rail flexible belt achieves a vibration absorbing effect to effectively absorb vibration in the grinding wheel finishing process; and the screw motor is adopted to drive at low constant speed, so that the microscopic texture uniformity after grinding wheel finishing is improved, and the grinding wheel shape precision is improved.

Description

technical field [0001] The invention belongs to the technical field of precision machining, and relates to a single-degree-of-freedom linear motion high-precision diamond pen grinding wheel dresser and an assembly method. Background technique [0002] Grinding belongs to finishing machining in mechanical processing. It has the advantages of less machining allowance and high machining accuracy, and is widely used in the machinery manufacturing industry. Especially for heat treated and quenched carbon tool steel and carburized and nitrided quenched steel parts, grinding has almost become a must. The tools used in the grinding process are grinding wheels. In addition to diamond grinding wheels, CBN grinding wheels and other non-dressable grinding wheels made of superabrasives, commonly used corundum grinding wheels and silicon carbide grinding wheels need to be dressed. Excellent shape accuracy of the grinding wheel, thus obtaining high machining accuracy of the workpiece. ...
