Finishing device and method for symmetrical double-cone-surface grinding wheel

Abstract

The invention belongs to the technical field of precise machining and provides a finishing device and method for a symmetrical double-cone-surface grinding wheel. To solve the problem of high-precision finishing of the symmetrical double-cone-surface grinding wheel, a method that mirror movement of diamond pen linear movement is formed through turning-over by 180 degrees is provided, and high-precision finishing of the symmetrical wheel double cone surfaces is realized. The finishing device for the symmetrical double-cone-surface grinding wheel comprises a diamond pen grinding wheel finisher,a flange bearing, a flange pin shaft, a finisher holder, a micrmeter head bracket, a ball head micrmeter head and a 180-degree turning-over and positioning device. The diamond pen finisher can rotatearound the finisher holder, and adjustment of any taper angle can be realized. Above all, the finishing device for the symmetrical double-cone-surface grinding wheel has only one guide rail system, has the advantages of being simple in structure, high in linear movement and turning-over movement precision and adjustable in taper angle and the like and has good market application prospect and popularization values.

Description

technical field [0001] The invention belongs to the technical field of precision machining, and relates to a dressing device and method for a symmetrical double-cone grinding wheel. Background technique [0002] Symmetrical double-cone grinding wheels are widely used in precision machining of parts with symmetrical tooth shapes such as threads, worms, gears, and end toothed discs. Regardless of the forming method or the Fancheng method, the dressing accuracy of the grinding wheel is one of the most critical factors affecting the machining accuracy of the part. For dressing methods of grinding wheels with symmetrical cone angles, there are mainly forming diamond roller dressing methods, digital grinding wheel dressing methods, and diamond pen dressing methods. [0003] The forming diamond roller dressing method is divided into two types: single roller and double roller. The diamond roller realizes the dressing of the conical grinding wheel by means of dressing extrusion, an...

Problems solved by technology

Two sets of this type of wheel dresser are used to achieve symmetrical double-cone grinding wheels, but for smaller size grinding wheels, it is difficult to arrange due to limited working space

In addition, two sets of linear guide rail systems are used to realize the dressing of the double-sided cone grinding wheel. The symmetrical accuracy of the installation positions of the two sets of guide rails will affect the dressing accuracy of the grinding wheel, and the cost is high
