Abstract
The utility model provides a support in high rigid rotation relates to bearing processing field, has 2 dabbers to constitute by 1 one end rigid coupling of supporter, and the other end of supporter 1 is equipped with fastening bolt 3, its characterized in that: dabber 2 go up the interference fit cover and be equipped with ball bearing 4, its tip is equipped with gland 6 through bolt 5. Have compact structure, it is high to support the rigidity, trades frock adjustment convenient and fast when living, can thoroughly solve the super smart fish tail problem of bearing bore diameter moreover, can improve product quality and production efficiency.
Description
Technical field
The utility model relates to the rotation inner support used of raceway in a kind of machining bearing, particularly about the high rigid rotating inner support that raceway in machining bearing superfinishing is used.
Background technology
During current bearing inner race microstoning, general fixed support supports inner ring internal diameter, be made up of supporter and back-up block, conventional back-up block is ceramic material, inner ring phase pair of interior support rotates, the relatively rotating of inner ring and support can be caused inner ring inside diameter surface to produce and be scratched, thus affects the quality of bearing, and adopts external diameter fixed support likely because the reason such as stressed destroys raceway precision.
Summary of the invention
For overcoming the shortcoming of prior art, the purpose of this utility model is to provide a kind of high rigidity and rotates inner support to improve the machining accuracy of bearing inner race.Fixed point sliding support be improved to rotary support, allow workpiece with support synchronous rotary, workpiece and support both of them do not produce slip, carry out the processing of superfinishing bearing inner race with this understanding.
Technical solution of the present utility model is: a kind of high rigid rotating inner support, be connected with mandrel by supporter one end formed, the other end of supporter is equipped with fastening bolt, it is characterized in that: on described mandrel, interference fit is set with ball bearing, and gland is equipped with by bolt in its end.
The internal diameter size of ball bearing external diameter and product to be processed coincide, by friction top, bearing is compressed again, be arranged on after nut check gland on super-fine machine tool, converted products internal diameter is enclosed within fulcrum ball bearing, workpiece spindle drives processed product to rotate, processed product drives fulcrum ball bearing outer ring to rotate, and realizes workpiece fricton-tight with support synchronous rotary.
Often process a kind of specification and select fulcrum ball bearing by internal diameter size, convenient and swift, bearing adopts interference play, best Ceramics ball ball bearing, ensures the high rigidity supported.
The utility model compared with the existing technology has compact conformation, and rigidity of support is high, and when changing alive, frock is fast easy to adjust, and thoroughly can solve bearing bore diameter superfinishing scuffing problem, can improve the quality of products and production efficiency.
