At present, most domestic Production of bearing enterprise falls behind with equipment due to process technology, and the bearing products produced belongs to low and middle-grade times mostly, and added value of product is low。Precision cylindrical roller and the high-grade base parts and components such as high-accuracy rolling body bearing, high-accuracy rolling body guide rail also rely on import, especially high end bearing, and China is even embargoed by developed country, seriously constrains the lifting of China's equipment integral level。In recent years, although China increases the input in the applied basic research and industrialization of the manufacture of important foundation part, but basic part manufacture level still exists bigger gap with developed country, there is in the urgent need to exploitation the basic part Ultraprecision Machining of independent intellectual property right。
At present, the mode of the domestic and international commonly used centerless grinding of batch machining of cylindrical roller, abrasion due to parts such as course of processing medium plain emery wheel, guide wheels, the processing conditions stability of each cylindrical roller is difficult to ensure that, thus being difficult to obtain high accuracy and the conforming cylindrical roller of height, recently as improving constantly equipment and instrument performance, precision and batch concordance to cylindrical roller propose increasingly higher requirement, it is necessary to develop the high accuracy of a kind of cylindrical component, high batch concordance batch processing method。Therefore, in the urgent need to developing the low cost batch processing method of a kind of applicable high accuracy, high concordance cylindrical roller。
Summary of the invention
In order to overcome the deficiency that precision is relatively low, concordance is poor of existing cylindrical component processing method, the present invention provides that a kind of precision is higher, concordance is good based on the partially auxobaric cylindrical component processing method of upper dish。
The technical solution adopted for the present invention to solve the technical problems is:
A kind of based on the partially auxobaric cylindrical component Excircle machining method of upper dish, the processing unit (plant) realizing described processing method includes top lap, retainer and lower abrasive disk, described top lap is positioned at above lower abrasive disk, described retainer is between top lap and lower abrasive disk, it is characterized in that: the rotating shaft of described retainer and the rotating shaft of lower abrasive disk are in being coaxially disposed, and the rotating shaft of the rotating shaft of described top lap and described lower abrasive disk exists determines offset distance；
Described processing method includes procedure below: be placed on the station of described retainer by cylindrical component to be processed, described top lap, retainer and lower abrasive disk can rotate alone around own torque by respective speed, charger in cylindrical component, coordinates abrasive material that cylindrical component cylindrical be processed by top lap and lower abrasive disc by top lap wobbler action。
Further, add man-hour, adopt fixed abrasive material or free abrasive to realize material and remove。
Further, the rotating shaft of described lower abrasive disk is hollow form, and the middle part of lower abrasive disk has through hole, and rotating shaft inner chamber and the through hole of described lower abrasive disk is passed in the rotating shaft of described retainer。
Further, the centre bore of described retainer is connected with the rotating shaft of retainer。
Described retainer is in the form of annular discs, the card of described retainer has for part to be processed place working groove, radially, concentric circles or lattice-shaped distribution。
The technology of the present invention is contemplated that: top lap, lower abrasive disk and retainer can rotate around own torque by respective rotating speed, and cylindrical component self rolls around the revolution of retainer center under the effect of upper and lower abrasive disk and retainer simultaneously, does complex space motion。Charger is by top lap wobbler action in cylindrical component, and cylindrical component exists certain relative sliding in the radial direction of top lap, is favorably improved material removing rate and ensures the linearity on the cylindrical component face of cylinder。Coordinate abrasive material that the cylindrical of cylindrical component is processed by top lap and lower abrasive disc。Owing to upper and lower abrasive disk is very smooth and parallel, and cylindrical part uniformly rolls, and after processing for a long time, trueness error and the scale error of each part fully homogenize, and may finally obtain high accuracy and the conforming cylindrical part of height。
Beneficial effects of the present invention is mainly manifested in: 1. once can the multiple workpiece of batch machining, the processing conditions of each workpiece is consistent, it may be achieved geometric accuracy that batch workpiece produces and the unification of dimensional accuracy；2. this method can realize the uniform rolling of cylindrical part, and cylindrical part cylindrical can obtain significantly high circularity；3. this method adopts highly smooth with parallel upper and lower abrasive disk that cylindrical part is processed, and cylindrical part bus can obtain significantly high linearity and the depth of parallelism；4. can adopt grinding, glossing, be substantially improved the surface quality of workpiece, it is thus achieved that very low surface roughness, it is achieved outer round surface not damaged is processed；5. in this method, the machining locus of cylindrical part outer round surface is extremely complex, can form staggered processing lines, is favorably improved workpiece fatigue life；6. realize cylindrical part high accuracy, high batch conforming batch machining, the Ultraprecision Machining of development bearing roller is significant。
