Abstract
The utility model relates to an O-shaped ring shaft shoulder suitable for a high-precision central spindle. The shaft shoulder comprises a central spindle matching section (1) and a central spindle detecting section (2). The outer circle of the central spindle is equal in diameter, and an O-shaped ring is arranged on the outer circle of the central spindle. A plurality of shallow arc grooves (3) are formed in the central spindle matching section. According to the O-shaped ring shaft shoulder suitable for the high-precision central spindle, a common fixing shaft shoulder is replaced with the O-shaped ring. The central spindle matching section is divided into a plurality of sections by the shallow arc grooves. Grinding stress on the surface of a workpiece is released and grinding area is reduced, so that the O-shaped ring shaft shoulder suitable for the high-precision central spindle is suitable for high-precision processing.
Description
Technical field
The utility model relates to a kind of under the machinery-free axial force condition, the O type circle shaft shoulder structure of isometrical cylindrical mandrel.
Background technology
When the detection position of test mandrel and matching part were same size, there was a shaft shoulder centre, and the axial limiting when using as this axle can not slide when being subjected to gravity and vibration.The shaft shoulder separates into two sections with cylindrical, limited by equipment precision, can't guarantee the positional precision of two ends cylinder.
Summary of the invention
For above deficiency, it is a kind of under the machinery-free axial force condition that the utility model provides, the O type circle shaft shoulder of isometrical cylindrical mandrel.
A kind of O type circle shaft shoulder that is applicable to the high accuracy mandrel comprises that mandrel cooperates section (1), mandrel detection segment (2), it is characterized in that the mandrel cylindrical is isometrical, and the mandrel cylindrical is provided with O type circle, cooperates section to be provided with several shallow arc grooves (3) at mandrel.
The present invention changes common fixedly shaft shoulder design with O type circle into substitutes; Cooperate section to be divided into several sections with shallow arc groove mandrel, discharge the surface of the work grinding stress, reduce the grinding area, adapt to high-accuracy processing.
