Abstract
The utility provides an external type machine tool for fixing a bearing inner ring, which comprises a shaft tire, a positioning core rod and a positioning sleeve, wherein the inner side of the shaft tire is connected with a machine tool spindle, a positioning hole is formed at the outer side of the shaft tire, and the positioning sleeve is arranged at the outer side of the positioning hole; one end of the positioning core rod is inserted into the positioning hole, and a fixed nut is arranged at the other end of the positioning core rod; and the surface of the outer side of the shaft tire is an inclined plane. The external type machine tool for fixing the bearing inner ring provided by the utility model has the beneficial effects that the structure of the shaft tire is changed, and an inclined channel bearing is fixed.
Description
Technical field
The utility model relates to a kind of lathe frock of external rigid bearing inner ring, belongs to the mechanical part field.
Background technology
The lathe frock is for bearing inner race being fixed on the ad-hoc location of lathe, plays the effect of location, fixed point, conveniently carries out next step processing operation, and fixing for valley road bearing, existing lathe frock is inapplicable.
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 external rigid bearing inner ring is provided, and realizes fixing valley road bearing.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of lathe frock of external rigid bearing inner ring, comprise axle tire, location mandril and positioning sleeve, the axle tire is inboard to be connected with machine tool chief axis, arranged outside has locating hole, the locating hole arranged outside has positioning sleeve, one end of location mandril inserts locating hole, and the other end is provided with hold-down nut, and the surface outside the axle tire is the inclined-plane.
Further, be set with interior positioning sleeve on location mandril.
The lathe frock of a kind of external rigid bearing of the utility model inner ring changes axle tire structure, has realized fixing valley road 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 external rigid bearing of the utility model inner ring.
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 external rigid bearing inner ring, comprise axle tire 1, location mandril 2 and positioning sleeve 3, axle tire 1 is inboard to be connected with machine tool chief axis 4, and arranged outside has locating hole, the locating hole arranged outside has positioning sleeve 3, bearing inner race 5 that first will be to be fixed is inserted in positioning sleeve 3, then location mandril 2 is passed bearing inner race 5, one ends insert locating hole, the other end is provided with hold-down nut 6, screws bearing inner race 5 is fixed on axle tire 1.When having the gap between bearing inner race 5 and location mandril 2, positioning sleeve 7 in can being set with on location mandril 2 is used for filling up gap between the two.
The surface in the axle tire outside is the inclined-plane, makes the plane of living in, valley road of the bearing inner race after fixing vertical with the axis of machine tool chief axis, has satisfied the requirement of postorder processing operation.
The lathe frock of a kind of external rigid bearing of the utility model inner ring changes axle tire structure, has realized fixing valley road 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.
