Description
Technical field
The present invention relates to high-precision sphere process equipment, especially a kind of spheroid conveying mechanism.
Background technology
High-precise ball is the critical elements in roundness measuring equipment, gyro, bearing and accurate measurement, and frequently as the base of accurate measurement
Standard, has highly important status in precision equipment and Precision Machining.Particularly use in a large number in ball bearing, be ball bearing
Vital part, the precision (spherical abberation, ball diameter variation and surface roughness) of bearing ball directly affects ball bearing
The technical specifications such as kinematic accuracy, noise and life-span, and then affect the performance of equipment, instrument.With traditional bearing steel ball material
(GCr15) comparing, the advanced ceramics material such as silicon nitride has wear-resisting, high temperature resistant, corrosion-resistant, nonmagnetic, low-density (for bearing steel
About 40%), coefficient of thermal expansion little (for the 25% of bearing steel) and elastic modelling quantity big (for 1.5 times of bearing steel) etc. are a series of excellent
Point is it is considered to be manufacture working shaft under ramjet, high speed and precision lathe, precision instrument high speed, high accuracy and special environment
Hold the optimal material of ball.
For the attrition process of Ceramic Balls, have some corresponding processing methods both at home and abroad, such as: V-shaped groove grinds, circle groove
Polishing, conical disc polishing, angle of rotation actively control polishing, magnetic suspension polishing etc..At V-shaped groove attrition process, circle ditch
In the courses of processing such as groove attrition process, conical disc attrition process, ball base can only be made " constant relative bearing " and grind motion, i.e. ball base
Spin axis the relative spacial orientation of hollow shaft is fixed, ball base is around a fixing spin axis rotation.Practice and theory analysis
It is disadvantageous for all showing that " constant relative bearing " grinds the grinding to ball of moving, and the contact point of ball base and abrasive disk is on ball base surface
The grinding trace formed is one group of annulus with the ball base axis of rotation as axle, and abrasive disk is along three coaxial circles traces of three contact points
Ball base carries out " repeated " grind, be unfavorable for that ball base surface obtains rapidly uniformly grinding, need to rely on ball in reality is processed
The phenomenons such as base skidding, agitation, make the spin axis of ball base occur slowly varying with the opposite piece orientation of hollow shaft, reach uniformly to grind
The purpose of mill, but the change of this spin angle is slowly, is random, uncontrollable, thus limit the sphericity of processing and add
Work efficiency rate.And angle of rotation actively controls to grind have the three pieces of abrasive disks that can independently rotate, can be by controlling lap speed
Change adjusts the orientation of the spin axis of ball base, and ball base can be made " change relative bearing " and grind motion, the grinding trace on ball base surface
It is the Spatial Sphere surface curve with the ball base axis of rotation as axle, it is possible to cover major part the most whole ball base surface, beneficially ball base table
Face obtains uniformly, grinds efficiently.In above-mentioned multiple method, for required device complexity, with tradition V-shaped groove processing side
Method is the easiest, and it is relative complex that magnetic suspension grinding and angle of rotation actively control processing method.
Technological deficiency present in existing structure: do not have Ceramic Balls cyclic process function, working (machining) efficiency relatively low, processing road
Footpath precise control is poor, processing concordance is poor.
Summary of the invention
In order to overcome the function of cyclic process without spheroid of existing high-precision ceramic balls process equipment, working (machining) efficiency is relatively low, add
The deficiency that work path clustering accuracy is poor, processing concordance is poor, the present invention provides that a kind of working (machining) efficiency is higher, machining path
