Description
技术领域technical field
本实用新型涉及精密球体加工技术领域，尤其是一种基于螺旋研磨槽旋转运动方式的球体加工装置。The utility model relates to the technical field of precision sphere processing, in particular to a sphere processing device based on the rotary motion mode of a spiral grinding groove.
背景技术Background technique
高精度球是圆度仪、陀螺、轴承和精密测量中的重要元件，并常作为精密测量的基准，在精密设备和精密加工中具有十分重要的地位。球体是滚珠轴承的关键零部件，轴承球的精度(球形偏差、球直径变动量和表面粗糙度)直接影响着球轴承的运动精度、噪声及寿命等技术指标，进而影响设备、仪器的性能。High-precision balls are important components in roundness meters, gyroscopes, bearings and precision measurement, and are often used as the benchmark for precision measurement, and play a very important role in precision equipment and precision machining. The ball is the key component of the ball bearing. The accuracy of the bearing ball (spherical deviation, ball diameter variation and surface roughness) directly affects the technical indicators such as the motion accuracy, noise and life of the ball bearing, which in turn affects the performance of equipment and instruments.
球体的加工方法对球体的加工精度和加工效率有着重要的影响。目前，国内外球体加工方法主要有V形槽研磨法、圆沟槽研磨法、自转角主动控制研磨法、磁悬浮研磨法等。在V形槽研磨加工、圆沟槽研磨加工、锥形盘研磨加工等加工过程中，球坯只能作“不变相对方位”研磨运动，即球坯的自转轴对公转轴的相对空间方位固定，球坯绕着一固定的自转轴自转。实践和理论分析都表明球体“不变相对方位”研磨运动对球体的研磨是不利的，球坯与研磨盘的接触点在球坯表面形成的研磨迹线是一组以球坯自转轴为轴的圆环，研磨盘沿着三接触点的三个同轴圆迹线对球坯进行“重复性”研磨，球坯表面不能迅速获得均匀研磨。所以，这三种加工方法在球体实际加工中需要依靠球坯打滑、搅动等，使球坯的自旋轴与公转轴的相对工件方位发生缓慢变化，以达到球坯均匀研磨的目的，但这种自转角的变化非常缓慢，是随机、不可控的，从而限制了球坯加工的球度和效率。自转角主动控制研磨法具有可独立转动的三块研磨盘，可以通过控制研磨盘转速变化来调整球坯的自旋轴的方位，球坯能作“变相对方位”研磨运动，球坯表面的研磨迹线是以球坯自转轴为轴的空间球面曲线，能够覆盖大部分甚至整个球坯表面，有利于球坯表面获得均匀、高效的研磨，但加工装置复杂。双转盘研磨方式在自转角主动控制研磨法的基础上，优化加工装置，三块磨盘只需其中两块旋转，另一块固定不动，通过调整磨盘的转速来实现球坯的“变相对方位”研磨运动。此方法优化了机构，但加工过程中只有一道沟槽，只有利于大尺寸球坯，同时球坯批量加工性有待提高。磁悬浮研磨方法的主要特征是采用磁流体技术实现对球坯的高效研磨，除了对球坯的加压的方式不同外，其研磨运动方式同V形槽研磨加工和锥形盘研磨加工中的运动方式基本相同，因此，在其加工过程中球坯研磨精度同样受到了限制。The processing method of the sphere has an important influence on the processing accuracy and efficiency of the sphere. At present, domestic and foreign sphere processing methods mainly include V-groove grinding method, circular groove grinding method, self-rotation angle active control grinding method, magnetic suspension grinding method, etc. In the process of V-groove grinding, circular groove grinding, conical disc grinding, etc., the ball blank can only perform the grinding movement of "constant relative orientation", that is, the relative spatial orientation of the rotation axis of the ball blank to the revolution axis Fixed, the billet rotates around a fixed axis of rotation. Both practice and theoretical analysis have shown that the "constant relative orientation" grinding motion of the ball is unfavorable to the grinding of the ball. The contact point between the ball blank and the grinding disc forms a grinding trace on the surface of the ball blank. The ring, the grinding disc performs "repeated" grinding on the ball blank along the three coaxial circular traces of the three contact points, and the surface of the ball blank cannot be quickly and uniformly ground. Therefore, these three processing methods need to rely on the sliding and stirring of the ball billet in the actual processing of the ball, so that the relative orientation of the spin axis and the revolution axis of the ball billet to the workpiece will change slowly, so as to achieve the purpose of uniform grinding of the ball billet, but this The change of the rotation angle is very slow, random and uncontrollable, which limits the sphericity and efficiency of billet processing. The self-rotation angle active control grinding method has three grinding discs that can rotate independently, and the orientation of the spin axis of the billet can be adjusted by controlling the rotation speed of the grinding disc. The grinding trace is a spatial spherical curve with the rotation axis of the billet as the axis, which can cover most or even the entire surface of the billet, which is conducive to uniform and efficient grinding of the billet surface, but the processing device is complicated. The double turntable grinding method is based on the active control grinding method of the rotation angle, and optimizes the processing device. Only two of the three grinding discs need to rotate, and the other one is fixed. By adjusting the rotation speed of the grinding discs, the "relative orientation" of the billet is realized. Grinding motion. This method optimizes the mechanism, but there is only one groove in the processing process, which is only beneficial to large-size ball blanks, and the batch processability of the ball blanks needs to be improved. The main feature of the magnetic levitation grinding method is the use of magnetic fluid technology to achieve high-efficiency grinding of the ball blank. Except for the different pressurization methods for the ball blank, the grinding movement method is the same as that in the V-shaped groove grinding process and the conical disc grinding process. The method is basically the same, therefore, the ball blank grinding accuracy is also limited during its processing.
高精度轴承、导轨等部件对球体零件的精度和一致性要求越来越高。因此，迫切需要开发一种适合高精度、高一致性球形零件(特别是直径小于12mm微小球体)高效、低成本的批量加工方法。Components such as high-precision bearings and guide rails have higher and higher requirements for the accuracy and consistency of spherical parts. Therefore, there is an urgent need to develop a high-efficiency, low-cost batch processing method suitable for high-precision, high-consistency spherical parts (especially tiny spheres with a diameter of less than 12 mm).
