Description
Technical field
The present invention relates to the processing of sphere technique, especially a kind of high-precision sphere process equipment.
Background technology
High-precise ball is the critical elements in roundness measuring equipment, gyro, bearing and accurate measurement, and often
As the benchmark of accurate measurement, precision equipment and Precision Machining have highly important status.
Particularly use in a large number in ball bearing, be the vital part of ball bearing.Precision (the ball of bearing ball
Shape deviation, ball diameter variation and surface roughness) directly affect ball bearing kinematic accuracy,
The technical specification such as noise and life-span, and then affect the performance of equipment, instrument.
The processing of sphere method has important impact to grinding precision and the efficiency of ball.At present, state
Inside and outside more existing corresponding method processing ball, mainly includes lap tool processing method and mill processing
Method.Lap tool processing method once can only grind a ball, and working (machining) efficiency is low, and precision is high.Mill
Polishing working (machining) efficiency is high, but precision is low, it include V-shaped groove polishing, circle groove polishing,
Conical disc polishing, angle of rotation actively control polishing, magnetic suspension polishing etc..At V-shaped groove
In attrition process, the circle course of processing such as groove attrition process, conical disc attrition process, ball base is only
" constant relative bearing " can be made and grind motion, the i.e. axis of rotation of the ball base space to hollow shaft
Orientation is fixed, and ball base is around a fixing axis of rotation rotation.Practice and theory analysis all show " no
Become relative bearing " to grind motion to the grinding of ball be disadvantageous, ball base exists with the contact point of abrasive disk
The grinding trace that ball base surface is formed is one group of annulus with the ball base axis of rotation as axle, abrasive disk edge
Three the coaxial circles traces three contact points carry out " repeated " grinding to ball base, are unfavorable for ball base
Surface obtains rapidly uniformly grinding.Need to rely on the skidding of ball base, agitation etc. existing in reality is processed
As, make the spin axis of ball base occur slowly varying with the opposite piece orientation of hollow shaft, reach equal
The purpose of even grinding, but the change of this angle of rotation is slowly, is random, uncontrollable,
Thus limit sphericity and the working (machining) efficiency of processing.And angle of rotation actively control that polishing has can
The independent three pieces of abrasive disks rotated, can adjust ball base by controlling lap speed change
The orientation of spin axis, ball base can be made " change relative bearing " and grind motion, the grinding mark on ball base surface
Line is the Spatial Sphere surface curve with the ball base axis of rotation as axle, it is possible to cover the most whole ball of major part
Base surface, beneficially ball base surface obtain uniformly, grind efficiently, but processing unit (plant) is complicated.
Double rotating disk lapping modes, on the basis of angle of rotation actively controls polishing, optimize processing unit (plant),
Three pieces of rotating disks only need wherein two pieces of rotations, and another block maintains static, by turning of regulation rotating disk
Speed realizes " the change relative bearing " of ball base and grinds motion.The method optimizes mechanism, but processes
During only one groove, be unfavorable for batch machining.The principal character of magnetic suspension Ginding process
It is the high-efficient grinding using magnetic fluid technique to realize ball base, except the mode of the pressurization to ball base
Outside difference, it grinds motion mode with the fortune in V-shaped groove attrition process and conical disc attrition process
Flowing mode is essentially identical, and therefore, in its course of processing, sphericity has been similarly subjected to limit.
Therefore, for the processing of high-precise ball, be badly in need of a kind of can realize higher machining accuracy and
Working (machining) efficiency and batch good high-precision sphere processing method.
Summary of the invention
In order to overcome existing the processing of sphere mode sphericity and working (machining) efficiency is low, processing concordance poor,
Processing unit (plant) and control complicated deficiency, the present invention provide a kind of can realize higher machining accuracy,
Working (machining) efficiency and the conforming high-precision sphere process equipment of processing.
The technical solution adopted for the present invention to solve the technical problems is:

Further, described compression system is spring load pressue device, hydraulic pulldown
Or air pressure pressue device；The combination of spring and other any pressuring method can also be used.
In the course of processing, described axle spiral half groove coaxially assembles with slip screw half groove, due to institute
State on separate type V-shaped groove every equal to axial line distance, therefore all processed balls in the course of processing
Body revolution speed and circulating path are identical, with tradition many raceway grooves concentric circular V-shaped groove inside and outside raceway groove turn
The unequal processing mode of speed is compared, and can realize the high consistency during the processing of sphere.Institute
The sleeve rotating stated is driven by sleeve driving means and rotates, and under non-at the uniform velocity rotational case, passes through
Adjust rotary speed and can realize the full envelope of spheroid；Under at the uniform velocity rotational case, the mechanism of device
Arrange that employing is horizontal, owing to self gravitation affects, add that the disturbance of external circulating system is more conducive to real
The existing full envelope of spheroid.Spheroid trueness error and scale error of sphere after cyclic process is abundant
Homogenization, finally can obtain high accuracy and the conforming spheroid of height.
Beneficial effects of the present invention is mainly manifested in: 1, the rotary speed of suitable adjustable sleeve, with
And disturbed by the gravity of spheroid self, it is achieved spheroid uniformly grinds；2, the revolution speed of ball is homogeneous
With, fabrication cycles path is the most identical, and processing concordance is good；3, the abrading-ball path length of helical structure,
Coordinating blood circulation, single batch ball load is big, can be efficiently obtained by high-precision sphere.
