Abstract
The utility model provides a machine tool for a built-in fixed bearing inner ring, which comprises a shaft tire and a nut. The inner side of the shaft tire is connected with a machine tool spindle; an inner hole is formed outside the shaft tire; and the nut is fixed at the top outside the shaft tire. The machine tool for the built-in fixed bearing inner ring, which is provided by the utility model, changes the structure of the shaft tire and realizes fixing on inner rings of large-scale bearings such as multichannel bearings.
Description
Technical field
The utility model relates to a kind of lathe frock of built-in rigid bearing inner ring, belongs to the mechanical part field.
Background technology
Before the bearing blind hole is processed operation, bearing inner race need to be fixed on the ad-hoc location of lathe, for the bearing inner race of many raceway grooves, greater than general bearing inner race, present lathe frock can't realize fixed function due to size.
The utility model content
The technical problems to be solved in the utility model is to overcome existing defective, and a kind of lathe frock of built-in rigid bearing inner ring is provided, and realizes fixing many raceway grooves bearing inner race.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of lathe frock of built-in rigid bearing inner ring comprises axle tire and nut, and the inboard of axle tire is connected with machine tool chief axis, and the arranged outside of axle tire has an endoporus, and nut is fixed on the top in the axle tire outside.
Further, in endoporus the diameter of lower cavity less than the diameter of upper cavity.
The lathe frock of a kind of built-in rigid bearing inner ring of the utility model changes the structure of axle tire, has realized fixing to such as the large scale bearing inner ring of many raceway grooves bearing.
Description of drawings
Accompanying drawing is used to provide further understanding of the present utility model, and consists of the part of specification, is used from explanation the utility model with embodiment one of the present utility model, does not consist of restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of the lathe frock of a kind of built-in rigid bearing inner ring of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of lathe frock of built-in rigid bearing inner ring, comprise axle tire 1 and nut 2, the inboard of axle tire 1 is connected with machine tool chief axis 3, the arranged outside of axle tire 1 has an endoporus, bearing inner race to be fixed 4 is placed in the middle of endoporus, and then the nut 2 with axle tire 1 outside top screws, and realizes fixing to bearing inner race 4.
In endoporus, the diameter of lower cavity is less than the diameter of upper cavity, and the location bearing inner ring, be convenient to implement blind hole processing better.
The lathe frock of a kind of built-in rigid bearing inner ring of the utility model changes the structure of axle tire, has realized fixing to such as the large scale bearing inner ring of many raceway grooves bearing.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although with reference to previous embodiment, the utility model is had been described in detail, for a person skilled in the art, it still can be modified to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
