Description
Technical field
The utility model belongs to field of machining technology, and in particular to a kind of thin-walled roller bearing noncircular raceway processing auxiliary
Device.
Background technique
The roller bearing outer rollaway nest of conventional structure is linear, and shape is normal structure, therefore the processing of outer rollaway nest uses
Conventional centerless fixture is able to satisfy product requirement；And to the roller bearing outer rollaway nest (as shown in Figure 1 and Figure 2) of noncircular raceway
For processing, ring face is with boss, the non-circular design of raceway bus shape, structure and complex-shaped, Product Precision height, effective wall
Thick only 1.7mm, belongs to the nonstandard roller bearing of thin-walled.The roller bearing outer ring processing of this class formation can not be real using conventional machine clamping method
It is existing, it is unable to satisfy user demand.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to propose a kind of thin-walled roller bearing noncircular raceway processing
Auxiliary device.
The utility model is to complete foregoing invention purpose to adopt the following technical scheme that
A kind of thin-walled roller bearing noncircular raceway auxiliary processing device, the auxiliary processing device have to position to
Process the abutment sleeve of thin-walled roller bearing；The abutment sleeve has matches with thin-walled roller bearing race diameter kissing to be processed
Through-hole, the blind hole I, convex with the end face of thin-walled roller bearing to be processed matched with thin-walled roller bearing race diameter kissing to be processed
The blind hole II that platform kissing is matched；The internal diameter height of the abutment sleeve is less than the height of thin-walled roller bearing to be processed；Described is blind
Hole I, blind hole II are connected with the through-hole；The center line of the blind hole I is overlapped with the center line of the abutment sleeve；
The thin-walled roller bearing to be processed that the auxiliary processing device is additionally provided with will be mounted in abutment sleeve carries out axial
The positioning cover plate of positioning；The positioning cover plate is connected as one by positioning screw and the abutment sleeve；Described determines
One end that position sleeve does not install thin-walled roller bearing to be processed is located in chuck；The chuck has to mounting and adjusting positioning sleeve
The central through hole of cylinder；The chuck is fixed in lathe attachment device.
The chuck is step structure.
The utility model proposes a kind of thin-walled roller bearing noncircular raceway auxiliary processing device, realize thin-walled Roller Shaft
Noncircular raceway processing is held, solves in production and processes bottleneck problem, meets the demand of user, while being the processing of similar product
It has been gained most valuable experience that, with simple, the easy to use feature of structure, efficiently solve in production and process bottleneck problem, and
It is promoted the use of in similar product.

Specific embodiment
The utility model is illustrated with reference to the drawings and specific embodiments:
As shown in figure 3, a kind of thin-walled roller bearing noncircular raceway auxiliary processing device, the auxiliary processing device have
To position the abutment sleeve 3 of thin-walled roller bearing to be processed；In conjunction with Fig. 4, the abutment sleeve 3 has to be rolled with thin-walled to be processed
The blind hole II 9 that the end face boss kissing of blind hole I 10 and thin-walled roller bearing to be processed that axle bearing race diameter kissing is matched is matched；
The sleeve diameter height matched with roller bearing outer ring outer diameter is less than the height of thin-walled roller bearing to be processed；Described
Blind hole I, blind hole II are that the through-hole is connected；The center line of the blind hole I is overlapped with the center line of the through-hole；It is described
Auxiliary processing device be additionally provided with and carry out axially position to the thin-walled roller bearing to be processed that will be mounted in abutment sleeve
Positioning cover plate 4；The positioning cover plate 4 is connected as one by positioning screw 5 with the abutment sleeve 6；Described determines
One end that position sleeve does not install thin-walled roller bearing to be processed is located in chuck；The chuck 2 has to install positioning sleeve
The central through hole of cylinder；The chuck 2 is fixed in lathe attachment device 1.
The chuck 2 is step structure.
When the utility model is used: the auxiliary machining device is connected using chuck 2 and lathe attachment device 1 and platen
It connects.Thin-walled roller bearing 7 to be processed is put on abutment sleeve 3, ring face be higher than 3 end face of abutment sleeve, positioning cover plate 4,
Gasket 6 and positioning bolt 5 fix thin-walled roller bearing to be processed.The end face boss of thin-walled roller bearing 7 to be processed and fixation
Locating slot on the abutment sleeve 3 of device is used counterclockwise or is rotated clockwise, and makes it close to the groove of abutment sleeve 3
Face, to guarantee positioning accuracy and machining accuracy.When being ground workpiece, abutment sleeve 3, thin-walled to be processed are rolled using positioning cover plate 4
The fixation device that sub- bearing 7, positioning bolt 5, gasket 6 form is fixed on chuck 2, adjustment abutment sleeve 3, thin-walled to be processed rolling
Radial direction, the end face positioning accuracy for the fixation device that sub- bearing 7 forms, are connect by lathe attachment device 1 with lathe.Positioning cover plate
4, positioning bolt 5, gasket 6 limit 7 axial freedom of thin-walled roller bearing to be processed and clamping.
