Curved-surface oscillating wheel dresser

Abstract

The invention relates to a curved-surface oscillating wheel dresser, and aims to provide a curved-surface oscillating wheel dresser, which is simple in structure, convenient to machine and manufacture, easy to operate, high in response speed, high in precision and high in efficiency, can quickly perform high-precision curved-surface dressing on a grinding wheel in the machining process of a machine tool, and effectively reduces the auxiliary time of grinding. The curved-surface oscillating wheel dresser is composed of a machine tool spindle, a curved surface grinding wheel, a dresser body anda dressing pen, wherein the curved surface grinding wheel is mounted on the machine tool spindle and rotates at a high speed along with the machine tool spindle; the dresser body is mounted on a machine tool, comprises a rotor rotating shaft perpendicular to the machine tool spindle, and can be in four-axis linkage with a linear shaft of the machine tool; and the dressing pen is mounted at the output end of the rotor rotating shaft through a dressing pen mounting base and can swing or rotate along with the rotor rotating shaft.

Description

technical field [0001] The invention belongs to the technical field of grinding, and in particular relates to a curved surface oscillating grinding wheel dressing device. Background technique [0002] With the development of aerospace, automobiles, molds, electronic products, and medical devices, the product forms are becoming increasingly diverse and complex, and the surface quality requirements are getting higher and higher. In order to achieve high-speed, high-efficiency, and high-precision Processing is often carried out by grinding. For complex curved surfaces, special-shaped forming grinding wheels are generally used for processing, and the forming grinding wheels are required to have high surface accuracy. However, after a period of use, the grinding wheels are prone to clogging of pores, passivation of gravel, and natural shedding. If the surface accuracy is not high, the grinding wheel must be dressed regularly. [0003] There are mainly two kinds of existing grin...

AI Technical Summary

Problems solved by technology

Because the diamond roller is independently driven to rotate at a high speed in this dressing method, in order to achieve high-precision grinding wheel surface dressing, the requirements for the installation accuracy, dynamic balance accuracy, rotation accuracy, stability and thermal elongation of the roller are relatively high, and the use of roller dressing also involves There are many parameters such as forward trimming, reverse trimming, trimming speed ratio, trimming cut-in feed, light trimming times, etc. The trimming process is complicated and difficult to operate

In addition, forming grinding wheels of different shapes need to be matched with rollers of different curved surfaces, which has poor versatility, frequent replacement during use, low efficiency, and high cost; and for complex curved surface shapes, it is difficult to manufacture rollers
