In engineering goods field, carrying carrier of the ball bearing as rotary part is commonly used, to make rotary part working stability
Reliably, the processing and manufacturing to ball bearing proposes the grinding of higher requirement, especially bearing inner race steel ball rolling channel, is to protect
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.
The content of the invention
It is an object of the invention to provide a kind of bearing inner race chuck, auxiliary during for grinding bearing inner ring steel ball rolling channel
Clamping tool, solves inconvenient, the ineffective problem of current clamping work.
To achieve the above object, the present invention provides following technical scheme：A kind of bearing inner race chuck, including body, it is described
Body is in stepped annular, and the right side of the body is provided with the less small end of diameter, the left side of the body be provided with diameter compared with
The big big end of circular thin-walled, the big end of thin-walled are provided with multiple ditches for making the big end of thin-walled produce radial contraction deformation
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, beneficial effects of the present invention are as follows：
1st, the present invention on the big end of thin-walled by setting the groove that can be deformed the big end of thin-walled, when bearing inner race is matched somebody with somebody with interference
For trap when on the big end of thin-walled is cylindrical, the endoporus of tensioner bearing inner race is understood at the big end of thin-walled because of elastic force caused by radial contraction deformation,
Ensure that bearing inner race location and installation is reliable, and it is easy to loading and unloading, improve operating efficiency.
2nd, a kind of bearing inner race chuck of the invention, the groove axially through the big end of thin-walled width, radially pass through
The walled thickness at the big end of thin-walled is worn, institute simultaneously arranges six along the big end of thin-walled is radially uniform, it is ensured that the big end of thin-walled produces enough changes
The endoporus of shape power tensioner bearing inner race, so as to ensure that crudy.
3rd, a kind of bearing inner race chuck of the invention, diameter is set to be more than the external diameter at the big end of thin-walled on the right side at the big end of thin-walled
Flange, the position-limiting action to bearing inner race is played, when bearing inner race is from the cylindrical of the left side at the thin-walled big end big end of push-in thin-walled
When, its right end face of bearing inner race is abutted the left side of flange, it is ensured that bearing inner race is by tensioner on the periphery at the big end of thin-walled.
4th, a kind of bearing inner race chuck of the invention, axial thread through hole is set in the inside of small end, be easy to by body with
Thread connecting mode, which fastens, to be arranged on grinding machine spindle, facilitates clamping.
5th, a kind of bearing inner race chuck of the invention, has that compact-sized, cost is low, clamping is easy for installation, operating efficiency
The advantages that high.
