Method for Dressing Concave Grinding Wheel with Linear Dresser

Abstract

The invention relates to a method for trimming a concave grinding wheel by using a linear trimmer. The method comprises the following steps: manufacturing an upper half body base and a lower half body base according to an original linear trimmer base, and combining the upper half body base and the lower half body base into a whole; mounting a trimmer mandrel onto a trimmer linear guide rail on the top surface of the base, adjusting the axis line of the trimmer mandrel fixed with a diamond pen to the middle of the trimmer linear guide rail, enabling the point of the diamond pen to be flush with the midpoint of the width of the grinding wheel, and pushing a piston in an oil cylinder of the diamond pen to be positioned in the midpoint of a piston travel; after adjustment, unscrewing a fastening hexagonal bolt for the upper half body base and the lower half body base of the trimmer, rotating by a certain angle with the point of the diamond pen as a circle center and the fastening bolt as a radius, so that the trimmer linear guide rail and the axis line of the grinding wheel are inclined, and slight depression is formed on the surface of the outer circle of the trimmed grinding wheel. The method disclosed by the invention mainly solves the problem that an R-30000 concave grinding wheel cannot be trimmed by a conventional trimmer and is simple in structure, strong in applicability and easy to operate.

Description

technical field [0001] The invention relates to a dressing technology of a mechanical grinding wheel, in particular to a method for dressing a concave grinding wheel by a linear dresser. Background technique [0002] Existing dressers are divided into linear dressers and curve dressers, and curve dressers are further divided into convex grinding wheel dressers and concave grinding wheel dressers. As long as the dresser moves linearly on the linear guide rail, it is called a linear dresser, and the cylindrical grinding wheel can be dressed. The curve trimmer has three trimming methods: curved guide rail type, fixed axis rotation type, and profiling plate type. The maximum trimming radius is only about 2000 mm. Due to structural limitations, larger radii cannot be trimmed. And the surface of the bearing cylindrical roller requires a slight convexity; the chord height is only 0.06 mm or R=30000 mm at a length of 120 mm, which cannot be realized on a conventional dresser.

Problems solved by technology

[0003] The technical problem to be solved in the present invention is, according to the problem that conventional dressers cannot dress R=30000 concave grinding wheels, a method for trimming concave grinding wheels with a straight line dresser is provided. The method is to process bearing cylindrical rollers, A method for dressing a concave grinding wheel with a convex roller on the outer surface of the tapered roller. This dresser has a simple structure, a wide price range, strong applicability, and easy operation.
