One of critical process of card ball bearing product quality, the grinding mode of conventional bearing inner race steel ball rolling channel, clamping be not square
Just, waste time and energy, often grinding accuracy does not reach design requirement also, causes product qualification rate relatively low.
Utility model content
The purpose of this utility model is to provide a kind of bearing inner race chuck, during for grinding bearing inner ring steel ball rolling channel
Auxiliary clamping tool, solves inconvenient, the ineffective problem of current clamping work.
To achieve the above object, the utility model provides following technical scheme：A kind of bearing inner race chuck, including body,
The body is in stepped annular, and the right side of the body is provided with the less small end of diameter, and the left side of the body is provided with directly
The larger big end of circular thin-walled in footpath, the big end of thin-walled make the big end of thin-walled produce radial contraction deformation provided with multiple
Groove.
Preferably, the groove axially through the big end of thin-walled width, extend radially through the walled thickness at the big end of thin-walled.
Preferably, the groove arranges six along the big end of thin-walled is radially uniform.
Preferably, the right side at the big end of the thin-walled is provided with the flange that diameter is more than the external diameter at the big end of thin-walled.
Preferably, the inside of the small end is provided with axial thread through hole.
Compared with prior art, the beneficial effects of the utility model are as follows：
1st, the utility model works as bearing inner race by setting the groove that can be deformed the big end of thin-walled on the big end of thin-walled
With interference fit be enclosed on the big end of thin-walled it is cylindrical upper when, the big end of thin-walled because radial contraction deform caused by elastic force can tensioner bearing inner race
Endoporus, it is ensured that bearing inner race location and installation is reliable, and easy to loading and unloading, improves operating efficiency.
2nd, a kind of bearing inner race chuck of the present utility model, the groove axially through the width at the big end of thin-walled, along footpath
Six are arranged to the walled thickness through the big end of thin-walled, institute and along the big end of thin-walled is radially uniform, it is ensured that the big end of thin-walled produces enough
Deformation force tensioner bearing inner race endoporus, so as to ensure that crudy.
3rd, a kind of bearing inner race chuck of the present utility model, diameter is set to be more than the big end of thin-walled on the right side at the big end of thin-walled
The flange of external diameter, the position-limiting action to bearing inner race is played, when bearing inner race is pushed into the big end of thin-walled from the left side at the big end of thin-walled
Outer bowlder, its right end face of bearing inner race is set to abut the left side of flange, it is ensured that bearing inner race is by tensioner in the cylindrical of the big end of thin-walled
On face.
4th, a kind of bearing inner race chuck of the present utility model, axial thread through hole is set in the inside of small end, is easy to this
Body is fastened with thread connecting mode and is arranged on grinding machine spindle, facilitates clamping.
5th, a kind of bearing inner race chuck of the present utility model, have it is compact-sized, cost is low, clamping is easy for installation, work
The advantages that efficiency high.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1, Fig. 2 and Fig. 3, a kind of bearing inner race chuck, including body 1 are referred to, the body 1 is in stepped annulus
Shape, the right side of the body 1 are provided with the less small end 2 of diameter, the left side of the body 1 be provided be relatively large in diameter it is circular thin
The big end 3 of wall, the big end 3 of thin-walled are provided with multiple grooves 4 for making the big end 3 of thin-walled produce radial contraction deformation.
The groove 4 axially through the big end 3 of thin-walled width, extend radially through the walled thickness at the big end 3 of thin-walled.
The groove 4 arranges six along the big end 3 of thin-walled is radially uniform.
The right side at the big end 3 of thin-walled is provided with the flange 5 that diameter is more than the external diameter at the big end 3 of thin-walled.
The inside of the small end 2 is provided with axial thread through hole.
A kind of bearing inner race chuck of the present utility model, during processing and fabricating, the external diameter at the big end 3 of thin-walled is than bearing inner race 6
