CNC roll grinder tooling adjustable center composite top pair

Abstract

The invention discloses an aligning type composite centre pair of a computer numerical control roll grinder tool. The aligning type composite centre pair comprises a reference base, a centre block and ejection blocks; three directions, every two of which are mutually perpendicular, are set as the direction x, the direction y and the direction z respectively; the axial direction of the reference base is the direction z, the centre block stops moving in the direction z and can be glidingly positioned on the reference base radially, and at least one group of the ejection blocks can be movably positioned on the surface of the reference base in the directions x and y respectively and are fixedly positioned with side walls of the centre block in the two mutually perpendicular directions respectively. The centre block is ejected by the ejection blocks to move on the reference base in the two mutually perpendicular directions, accordingly, fine adjustment of the axis position of the centre block is realized, and concentricity of the centre block and outer circles of two bearing retainers on a spindle is realized. The aligning type composite centre pair is simple in structure and convenient to operate, can be used for grinding the outer circles of the two bearing retainers on the grinding spindle, an outer circle of a cone meeting the grinding wheel mount reference being 1:30, an outer circle of a cone meeting the mount reference, namely, 1:5, of a grinding wheel on a grinding head taper sleeve and the like, and is high in universality and convenient to process and manufacture.

Description

technical field [0001] The invention relates to a numerically controlled roll grinder tooling, in particular to an adjustable centering composite top pair of the numerically controlled roll grinder tooling. Background technique [0002] The key component of the CNC roll grinder is the "grinding head component". The internal part "spindle / taper sleeve" is the core part of the component, and its manufacturing precision belongs to the A-level importance. [0003] For a long time, for the key process of "spindle / taper sleeve" machining "finish grinding", the traditional processing method - top grinding between two centers has been used. Due to the limitation of the "grinding head spindle" structure, there is a φ22 through hole in the axial center and a φ70H7 reference hole in the big end. The positioning datum (top hole) cannot be made on the two ends of the main shaft, so "top grinding tooling" has to be added on the two ends. And make it up to the standard in the precision ...
