Description
Technical field
The present invention relates to cylindrical component top circle processing device, especially one grind based on biplane
The cylindrical component top circle processing device of mill.
Background technology
At present, most domestic Production of bearing enterprise falls behind with equipment due to process technology, is given birth to
The bearing products produced belongs to low and middle-grade times mostly, and added value of product is low.Precision cylindrical roller and height
The high-grade base parts and components such as precision rolling body bearing, high-accuracy rolling body guide rail also relies on import,
The most high-end bearing, China is even embargoed by developed country, seriously constrains China's equipment entirety
The lifting of level.In recent years, although China increases the application foundation manufactured at important foundation part
Input in terms of research and industrialization, but basic part manufacture level still exists relatively with developed country
Big gap, has the basic part Ultraprecision Machining of independent intellectual property right in the urgent need to exploitation.
At present, the mode of the domestic and international commonly used centerless grinding of batch machining of cylindrical roller, by
In the abrasion of the parts such as course of processing medium plain emery wheel, guide wheel, the processing conditions of each cylindrical roller is steady
Qualitative it is difficult to ensure that, thus is difficult to obtain high accuracy and the conforming cylindrical roller of height, in recent years
Along with improving constantly equipment and instrument performance, precision and batch concordance to cylindrical roller propose
The highest requirement, it is necessary to develop the high accuracy of a kind of cylindrical component, high batch
Concordance batch processing method.Therefore, applicable in high precision in the urgent need to exploitation one, high consistent
The low cost batch machining device of property cylindrical roller.
Summary of the invention
In order to the precision overcoming existing cylindrical component top circle processing device is relatively low, concordance is poor
Deficiency, the present invention provides a kind of precision is higher, concordance is good upper dish eccentric compression type circle
Cylindrical parts top circle processing device.
The technical solution adopted for the present invention to solve the technical problems is:
Dish eccentric compression type cylindrical component top circle processing device in one, including top lap,
Retainer and lower abrasive disk, described top lap is positioned at above lower abrasive disk, described retainer position
Between top lap and lower abrasive disk, the rotating shaft of described retainer and the rotating shaft of lower abrasive disk in
Being coaxially disposed, the rotating shaft of described top lap determines offset distance with the rotating shaft existence of described retainer,
Charger is positioned on described top lap.
Further, the rotating shaft of described lower abrasive disk is hollow form, and the middle part of lower abrasive disk has logical
Hole, the rotating shaft of described retainer passes rotating shaft inner chamber and the through hole of described lower abrasive disk.
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 and puts for part to be processed
The processing groove put, radially, concentric circles or lattice-shaped distribution.
The technology of the present invention is contemplated that: top lap, lower abrasive disk and retainer can be by each
Rotational speed；Cylindrical component under the effect of upper and lower abrasive disk and retainer around retainer
Self roll while the revolution of center, make complex space motion.Charger passes through top lap
Wobbler action exists slight in cylindrical component, cylindrical component in the radial direction of top lap
Relatively slide, be favorably improved material removing rate and ensure the linearity on the cylindrical component face of cylinder.
Coordinate abrasive material that the cylindrical of cylindrical component is added by top lap and lower abrasive disc
Work.Owing to upper and lower abrasive disk is the most smooth and parallel, and cylindrical part uniformly rolls, and passes through
After long-time processing, trueness error and the scale error of each part fully homogenize, and finally can obtain
Obtain high accuracy and the conforming cylindrical part of height.
Beneficial effects of the present invention is mainly manifested in: the most once can the multiple workpiece of batch machining, often
The processing conditions of individual workpiece is all consistent, can realize geometric accuracy and chi that batch workpiece produces
The unification of very little precision；2. this method can realize the uniform rolling of cylindrical part, outside cylindrical part
Circle can obtain the highest circularity；3. this method uses the most smooth with parallel upper and lower abrasive disk
Being processed cylindrical part cylindrical, cylindrical part bus can obtain the highest linearity with parallel
Degree；4. can use grinding, glossing, be substantially improved the surface quality of workpiece, it is thus achieved that the lowest
Surface roughness, it is achieved outer round surface not damaged process；5. cylindrical part cylindrical in this method
Machining locus on surface is extremely complex, can form staggered processing lines, be favorably improved work
Part fatigue life；6. realize cylindrical part high accuracy, high batch of conforming batch machining, to sending out
The Ultraprecision Machining of exhibition bearing roller is significant.
