Concave-convex small sphere grinding wheel dresser

Abstract

The invention discloses a concave-convex small sphere grinding wheel dresser which comprises a planar base and a vertically arranged upper bracket, wherein the base is provided with a clamping device capable of being fixed to a grinding machine working platform, the upper part of the upper bracket is provided with a diamond pen and a feeding mechanism, the middle of the left end of the base is vertically provided with a sleeve, and the lower part of the left end of the upper bracket is rotatably sleeved on the sleeve. The concave-convex small sphere grinding wheel dresser is characterized in that a standard lever is inserted into the sleeve, the upper end of the standard lever is in a semi-column shape and is corresponding to the diamond pen; and the feeding mechanism comprises a fixed sleeve, a front sliding sleeve, a rear sliding sleeve, a gauge block, a differential screw and other members. The processing base point calibration is carried out on the pen point of the diamond pen by using the standard lever, a blocking jaw is used for ensuring that the upper bracket is positioned at the standard position during the calibration, the processing feeding position is determined by using the gauge block, the fine adjustment is carried out by using the differential screw, therefore, the invention can realize accurate measurement on the processing size without depending on the subjective judgment of a processor, and ensures the accuracy of the processing size can reach higher standard.

Description

technical field [0001] The invention relates to an apparatus capable of processing grinding wheels, in particular to a concavo-convex small spherical grinding wheel dresser. Background technique [0002] Spherical parts are generally processed with a spherical sample knife with a certain margin, and then ground with a spherical grinder. When there is no spherical grinder, if you want to use an ordinary grinder to process inner and outer spherical parts with precise dimensions, you need to design a A device capable of modifying and processing the spherical surface of a grinding wheel, using a grinding wheel that meets the size of the repairing part of the device, and then processing parts with the grinding wheel. my country's Patent No. 200520146848.1 once announced a kind of inner and outer spherical grinding wheel dresser, which consists of base, mandrel, body, adjusting bolt, telescopic sleeve, diamond pen, bushing, knob, handle, limit screw, locking Screws, nuts and compo...

AI Technical Summary

Problems solved by technology

The inner and outer spherical grinding wheel dresser can be used to dress the spherical surface of the grinding wheel, but because the equipment has no calibration reference and feed reference, the size of the processing volume is completely controlled by the operator based on experience, so it is difficult to obtain the processing size accuracy.
