Grinding wheel arc dresser

Abstract

A grinding wheel arc dresser comprises a substrate, an extension board, a rotating body, a tool rest and a finishing tool body, wherein the extension board is fixedly connected with the rotating body in the substrate; the extension board is fixedly connected with the tool rest; the finishing tool body is moveably arranged on the tool rest; and the tool rest is also provided with an adjustment mechanism which can be adjusted to make the finishing tool body move relative to the tool rest. The grinding wheel arc dresser can rapidly and accurately adjust a tool tip of the finishing tool body relative to the height of a reference plane and is favorable for improving the work efficiency and the machining accuracy.

Description

technical field [0001] The invention relates to a grinding wheel dresser, in particular to a grinding wheel arc dresser for dressing the grinding wheel arc. Background technique [0002] In the field of precision grinding, grinding wheels of different shapes are usually used to process various types of die core parts, among which the arc grinding wheel is trimmed by an arc dresser. During the processing, the grinding wheel cuts the surface of the workpiece with tiny particles, and the grinding wheel particles will gradually fall off, resulting in the reduction of the grinding surface accuracy of the grinding wheel and the dulling of the grinding wheel particles, making it impossible to process effectively. Therefore, after the grinding wheel has been used for a period of time, it is usually necessary to use a grinding wheel dresser to dress the grinding wheel, so that the grinding wheel can regain the precise arc surface and the sharpness of cutting. The dressing of arc gri...

Problems solved by technology

[0005] The above-mentioned grinding wheel arc dresser has the following defects: when adjusting the height of the tip of the cutter bar 61, that is, the height of the tip of the cutter from the reference plane, it is necessary to release the lock on the trimming cutter body 50, and then use a copper rod or the like to strike the trimmer. cutter body 50, the cutter body 50 is moved to a preset position in the clamping groove of the cutter seat 60, and the height of the tip of the cutter bar 61 is measured by a measuring device such as a height gauge. Knocking, repeated adjustment and measurement, the efficiency is low, and, when locking the cutter body 50, the height of the tip of the cutter will also change, reducing the accuracy of adjustment

At the same time, during the adjustment process, the movement of the grinding wheel arc dresser and the unevenness of the end of the height gauge in contact with the tool tip will cause the height of the tool tip to deviate from the reference plane, which is time-consuming to adjust and difficult to ensure precision
