Description
Technical field
It is especially a kind of based on spiral grinding groove rotary movement the present invention relates to precise sphere processing technique field
Ball grinding device.
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, there is highly important status in precision equipment and Precision Machining.Spheroid is the key components and parts of ball bearing, bearing ball
Precision (spherical abberation, ball diameter variation and surface roughness) directly affect kinematic accuracy, noise and the longevity of ball bearing
The technical indicators such as life, and then influence equipment, the performance of instrument.
The processing method of spheroid has important influence to the machining accuracy and processing efficiency of spheroid.At present, domestic ectosphere
Body processing method mainly has V-shaped groove polishing, circle groove polishing, angle of rotation active control polishing, magnetic suspension polishing etc..
In the process such as V-shaped groove attrition process, circle groove attrition process, conical disc attrition process, ball base can only be made " constant relative
Orientation " grinding motion, i.e., the axis of rotation of ball base is fixed to the relative spacial orientation of hollow shaft, and ball base is around the axis of rotation fixed
Rotation.Practice and theory analysis all show that grinding of spheroid " constant relative bearing " the grinding motion to spheroid is unfavorable, ball base
In the grinding trace that ball base surface is formed it is one group of annulus using the ball base axis of rotation as axle with the contact point of abrasive disk, abrasive disk edge
Three coaxial circles traces for three contact points carry out " repeatability " grinding to ball base, and ball base surface can not rapidly obtain and uniformly grind
Mill.So these three processing methods need the spin axis for by the skidding of ball base, agitation etc., making ball base in spheroid actual processing
It is slowly varying with the opposite piece orientation generation of hollow shaft, to reach the purpose that ball base is uniformly ground, but the change of this angle of rotation
Change is very slow, is random, uncontrollable, so as to limit the sphericity and efficiency of the processing of ball base.Angle of rotation active control is ground
Method has the three pieces of abrasive disks that can independently rotate, can be by controlling lap speed change to adjust the side of the spin axis of ball base
Position, ball base can make " change relative bearing " grinding motion, and the grinding trace on ball base surface is the Spatial Sphere using the ball base axis of rotation as axle
Surface curve, most of or even whole ball base surface can be covered, be advantageous to ball base surface and obtain uniform, efficient grinding, but add
Frock puts complexity.Double rotating disk lapping modes optimize processing unit (plant), three pieces of mills on the basis of angle of rotation active control polishing
Wherein two pieces rotations are only needed, another piece fixed, realizes that " the change relative bearing " of ball base is ground by adjusting the rotating speed of mill
Mill motion.The method optimizes mechanism, but there was only one of groove in process, only beneficial to large scale ball base, while ball base
Batch machining has much room for improvement.Magnetic suspension Ginding process is mainly characterized by efficiently the grinding to ball base using magnetic fluid technique realization
Mill, in addition to the mode of the pressurization to ball base is different, it grinds motion mode with V-shaped groove attrition process and conical disc attrition process
In motion mode it is essentially identical, therefore, in its process ball base grinding precision be similarly subjected to limitation.
Precision and coherence request more and more higher of the parts such as high-precision bearing, guide rail to sphere part.Therefore, compel to be essential
Develop a kind of suitable high accuracy, high uniformity bulb (is particularly diameter and is less than 12mm microspheres) efficient, low cost
Batch processing method.
The content of the invention
In order to overcome the shortcomings of that the precision of existing the processing of sphere mode is relatively low, uniformity is poor, the invention provides one
Kind can realize that high accuracy, high efficiency, high uniformity and the grinding of spheroid (particularly diameter is less than 12mm microspheres) processing (are thrown
Light liquid) the processing unit (plant) that uses of high efficiency, the device passes through spiral grinding groove rotary motion, constantly changes ball in process of lapping
The axis of rotation angle of base, realize that grinding groove is processed to the full envelope in ball base surface.
