Abstract
The invention discloses a bearing ring superfinishing tool and centering sleeve. The superfinishing tool comprises a centering shaft, a bearing which is fixedly connected to the centering shaft in a sleeving mode, a centering sleeve which is fixedly connected to the outer ring of the bearing in a sleeving mode, a locking screw which is connected to the end of the centering shaft and used for fixing the centering sleeve and a backing part used for axially locating a ring workpiece on the centering sleeve; the centering sleeve comprises a circular tube-shaped sleeve body, an outer locating ring which is integrally formed on the outer periphery of the end, far away from the locking screw, of the sleeve body and used for locating the ring workpiece and an inner locating ring which is integrally formed on the inner periphery of the end, close to the locking screw, of the sleeve body, and the inner locating ring is fixed between the locking screw and the outer ring of the bearing in a clamped mode. An original pressing wheel is replaced with the outer locating ring integrally formed on the centering sleeve, machining of the tool is easier, and the machining cost is reduced; installing and adjusting are easier, the production cost of a workshop is greatly reduced, the production efficiency of the workshop is greatly improved, and the appearance quality of the superfinished bearing ring is improved.
Description
Technical field
The invention belongs to bearing machining apparatus field, be specifically related to a kind of bearing ring superfinishing frock and centring sleeve.
Background technology
Traditional bearing inner race superfinishing centring sleeve is split type, is through on lasso endoporus by centring sleeve during lasso superfinishing,
Play support lasso effect, have two independent pinch rollers to be pressed on ring face simultaneously, make lasso be pressed on backer.Foregoing
Mode have that following some is not enough:
1, die craft equipment centring sleeve is split type, manufacture processing more complicated, fabrication cycle is the most elongated, cost of manufacture also than
Higher；
2, need centring sleeve and pinch roller are adjusted before the number of remodeling every time, adjust part many, adjust the time longer, the most significantly
Have impact on Workshop Production efficiency；
3, it is separate two parts due to centring sleeve and pinch roller, when adjusting pinch roller, is not easy centering, in the opposing ferrules of pinch roller center
Heart deviation can cause linear velocity inconsistent and skid anti-, leaves the impression of black at ring face, affects product appearance.
Summary of the invention
The technical problem to be solved is: the deficiency existed for prior art, it is provided that a kind of process and assemble letter
Single, low cost, the bearing ring superfinishing centring sleeve of presentation quality and use this centring sleeve after being beneficial to improve bearing inner race superfinishing
Frock.
For realizing the purpose of the present invention, it is achieved by the following technical solutions: a kind of bearing ring superfinishing frock, including
There are centration axis, fixedly sleeved bearing in centration axis, fixedly sleeved centring sleeve on described bearing outer ring, and are connected to
Centration axis end in order to by lock-screw fixing for centring sleeve；Also include in order to lasso workpiece is axially positioned on centring sleeve
On backer；Described centring sleeve includes the body of round tube shape, one-body molded at body away from periphery, lock-screw one end
For positioning the outside fix circle of lasso workpiece, and one-body molded at body near the inner position circle of lock-screw one end inner circumferential；
Described inner position circle is fixedly clamped between described lock-screw and the outer ring of bearing.
Preferably: between described lock-screw and centring sleeve, pad is installed.
Preferably: the body of described centring sleeve is positioned at the end, one end of inner position circle and forms taper surface, taper
The cone angle in face is 30 °.
The present invention also provides for a kind of bearing ring superfinishing centring sleeve, includes the body of round tube shape, one-body molded at set
Body is away from the outside fix circle for positioning lasso workpiece of periphery, lock-screw one end and one-body molded in the close locking of body
The inner position circle of screw one end inner circumferential；Described body is positioned at the end, one end of inner position circle and forms taper surface, the cone of taper surface
Angle is 30 °.
Compared with prior art, the invention has the beneficial effects as follows:
1, using one-body molded outside fix circle on centring sleeve to replace original pinch roller, frock processing is simpler, reduces
Processing cost；
2, installation and debugging are simpler, greatly reduce the production cost in workshop and improve production efficiency；
3, improve the presentation quality after bearing inner race superfinishing.

Detailed description of the invention
Below according to accompanying drawing, the detailed description of the invention of the present invention is made a detailed explanation.
Embodiment 1
According to Fig. 2, the present embodiment is a kind of bearing ring superfinishing centring sleeve, includes the body 32 of round tube shape, one
Body formed body away from periphery, lock-screw one end for positioning the outside fix circle 31 of lasso workpiece, and one-body molded
Body is near the inner position circle 33 of lock-screw one end inner circumferential；Described inner position circle is fixedly clamped at described lock-screw and bearing
Outer ring between；Described body is positioned at the end, one end of inner position circle and forms taper surface 34, and the cone angle of taper surface is 30 °.
Embodiment 2
According to Fig. 1, the present embodiment is the bearing ring superfinishing frock that have employed embodiment centring sleeve, includes centration axis 4,
Fixedly sleeved bearing 7 in centration axis, fixedly sleeved centring sleeve 3 on described bearing outer ring, and it is connected to centration axis
End in order to by lock-screw 5 fixing for centring sleeve；Also include in order to lasso workpiece is axially positioned on centring sleeve
Backer 1；Described centring sleeve includes the body 32 of round tube shape, one-body molded at body away from the use of periphery, lock-screw one end
In the outside fix circle 31 of location lasso workpiece, and one-body molded at body near the inner position circle of lock-screw one end inner circumferential
33；Described inner position circle is fixedly clamped between described lock-screw and the outer ring of bearing.
Pad 6 is installed between described lock-screw and centring sleeve.
The body of described centring sleeve is positioned at the end, one end of inner position circle and forms taper surface 34, and the cone angle of taper surface is
30°。
During assembling, bearing is contained in centration axis, then centring sleeve is sleeved on the outer ring of bearing, with lock-screw and
Centring sleeve is locked by pad, then centration axis is installed on lathe；After installing backer, lasso workpiece 2 to be processed
