The case where hindering directly affects the qualification rate of product.
Invention content
The purpose of the present invention is to solve the above-mentioned problems of the prior art, provide a kind of for bearing outer ring channel
The positioning device of ultraprecision grinding process, accurate positioning, can make the bearing groove curvature processed uniformly, contour shape one
It causes, the shape of bearing products is avoided the phenomenon that being pulled occur.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme that：One kind being used for bearing outer ring channel superfinishing
The positioning device of close grinding process includes two guide wheels for bearing to be clamped and rotates with dynamic bearing and for abutting against axis
The baffle for holding outer end face further includes pressure rotor and supporting block, and the pressure rotor is arranged with coaxial bearing, the pressure rotor
Front end face abut against the inner face of bearing, oil outlet is offered on the front end face of the pressure rotor, in the pressure rotor
Oil pocket equipped with connection oil outlet, the supporting block are resisted against the side of bearing, and the supporting block is located between two guide wheels.
Preferably, two guide wheels are separately positioned on the top and lower section of bearing, and the position for being located at the guide wheel above bearing can
It adjusts, to can adjust the clamping gap between two guide wheels.
It is highly preferred that the axle center of two guide wheels mutually staggers in the vertical direction.
It is highly preferred that two vertical line interval 6-8cm where the axle center difference of two guide wheels.
It is highly preferred that the supporting block is made of Steel material.
The beneficial effects of the present invention are：Bearing is clamped by double guide wheels, then uses pressure rotor against the inner end of bearing
Face makes the outer end face of bearing be posted by baffle, thus prevents bearing to generate shaking when carrying out high-speed rotation, with bearing products
End face positioning accuracy can be improved as positioning datum, ensure bearing products verticality, while can also make the axis processed
It holds that ditch curvature is uniform, contour shape is consistent, the shape of bearing products is avoided the phenomenon that being pulled occur.
Description of the drawings

Specific implementation mode
For the ease of the understanding of those skilled in the art, the present invention is made further with reference to embodiment and attached drawing
Bright, the content that embodiment refers to not is limitation of the invention.
It needs to illustrate in advance, in the present invention unless specifically defined or limited otherwise, term " installation ", " phase
Even ", the terms such as " connection ", " fixation " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection,
Or it is integrally connected；It can be directly connected, can also can be indirectly connected through an intermediary the company inside two elements
It is logical.For the ordinary skill in the art, above-mentioned term in the present invention specific can be understood as the case may be
Meaning.
In addition, in the present invention unless specifically defined or limited otherwise, fisrt feature is "above" or "below" second feature
It may include that the first and second features are in direct contact, can also not be to be in direct contact but pass through it including the first and second features
Between other characterisation contact.Moreover, fisrt feature second feature " on ", " top " and " above " include first special
Sign is right over second feature and oblique upper, or is merely representative of fisrt feature level height and is higher than second feature.Fisrt feature exists
Second feature " under ", " lower section " and " following " include fisrt feature immediately below second feature and obliquely downward, or be merely representative of
Fisrt feature level height is less than second feature.Term "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal",
The orientation or positional relationship of the instructions such as "top", "bottom" "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, and is only
For convenience of description of the present invention and simplification of the description, specific side must be had by not indicating or implying the indicated device or element
Position, with specific azimuth configuration and operation, therefore be not considered as limiting the invention.
As shown in Figs. 1-2, it is used for the positioning device of bearing outer ring channel ultraprecision grinding process, including is used to that bearing to be clamped
1 and two guide wheels 2 rotated with dynamic bearing 1 and baffle 3 for abutting against 1 outer end face of bearing, further include 4 He of pressure rotor
