Abstract
The utility model provides a novel grinding wheel dresser gyration device, includes pivot, packing ring, bearing a, casing, spring, sleeve, bearing b, bearing an and bearing b cover is in the outside of pivot, and casing 4 sets up in bearing an and bearing b outside, and the casing inboard is provided with the arch, bearing a's one end is hugged closely to protruding one end, the outside of pivot still is provided with the sleeve, bearing b is hugged closely to sleeve one end, set up the spring between bulge and the sleeve. This invents simple structure, and is workable, has apparent positive role to the wheel Truing of bearing channel grinding in -process, can lengthen the life of wheel Truing device and the precision of guaranteeing to repair the circular arc to improve production efficiency.
Description
Technical field
The invention belongs to bearing machining field, especially relate to a kind of grinding wheel trimmer swivel gear.
Background technique
Known, the grinding of bearing channel is a vital procedure in Production of bearing processing, and the grinding shape of raceway groove and ditch shape are one of key factors wherein affecting raceway groove grinding quality quality, but ditch shape is but also unstable in production and processing, and the factor affecting ditch shape is exactly the finishing shape of emery wheel, namely on lathe, the precision of grinding wheel dresser is high, the accuracy to shape also corresponding raising of its trimming wheel.
But, the rotating accuracy of present lathe grinding wheel dresser is but not high, because its turning axle two ends mainly rely on conical surface to position and revolution, and through rubbing repeatedly between conical surface, contact surface abrasion after a period of time, precision just can be lost, and the grinding wheel shape of repairing out does not just meet technological requirement, does not also meet technological requirement with the bearing channel that this emery wheel processes.
Summary of the invention
In order to overcome the deficiency in background technique, the invention discloses a kind of grinding wheel trimmer swivel gear.Can realize repairing accurately bearing channel grinding wheel, improve the grinding accuracy of bearing channel, and extend the working life of grinding wheel dresser.
In order to realize described goal of the invention, the present invention adopts following technological scheme:
A kind of grinding wheel trimmer swivel gear, comprises rotating shaft, packing ring, bearing a, housing, spring, sleeve, bearing b; Described bearing a and bearing b is enclosed within the outside of rotating shaft, and it is outside that housing 4 is arranged on bearing a and bearing b, and case inside is provided with projection, and one end of bearing a is close in described protruding one end; The outside of described rotating shaft is also provided with sleeve, and bearing b is close in described sleeve one end, arranges spring between described convex portion and the other end of sleeve.
The inner ring of bearing a of the present invention and bearing b and rotating shaft interference fit.
The bearing a the other end in rotating shaft of the present invention is also provided with packing ring.
The end face of rotating shaft of the present invention is also provided with locking nut.
Owing to have employed technique scheme, the present invention has following beneficial effect: swivel gear of the present invention is loaded the position be connected with lathe, housing is fixed, by the hydraulic control of lathe, drive rotating shaft rotates, thus realizes the smooth rotation of the relative housing of rotating shaft.Bearing a and bearing b plays supporting revolving shaft, guide the effect of rotary motion, it reduces the sliding friction that original device causes owing to being slidably matched greatly, reduce the wearing and tearing that mechanical part causes due to friction, more substantially the kinematic accuracy stopping to cause due to contact wearing and tearing is lost, thus substantially increases the dressing accuracy of emery wheel.
This invention structure is simple, easily processes, has significant positive role to the grinding wheel dressing in bearing channel grinding process, can extend the working life of wheel dresser and ensure the precision of finishing circular arc, thus enhancing productivity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, rotating shaft; 2, packing ring; 3, bearing a; 4, housing; 5, spring; 6, sleeve; 7, bearing b; 8, locking nut.
Embodiment
By explanation the present invention that the following examples can be detailed, disclose object of the present invention and be intended to protect all technological improvements in the scope of the invention.
A kind of grinding wheel trimmer swivel gear, comprises rotating shaft 1, packing ring 2, bearing a3, housing 4, spring 5, sleeve 6, bearing b7; Described bearing a3 and bearing b7 is enclosed within the outside of rotating shaft 1, and it is outside that housing 4 is arranged on bearing a3 and bearing b7, and be provided with projection inside housing 4, one end of bearing a3 is close in described protruding one end; The outside of described rotating shaft 1 is also provided with sleeve 6, and bearing b7 is close in described sleeve 6 one end, arranges spring 5 between described convex portion and sleeve 6.
The inner ring of bearing a3 of the present invention and bearing b7 and rotating shaft 1 interference fit.
The bearing a3 the other end in rotating shaft 1 of the present invention is also provided with packing ring 2.
The end face of rotating shaft 1 of the present invention is also provided with locking nut 8.
This device is assembled in order, tighten locking nut 8, make spring 5 produce compression, the inner ring of bearing a3 and bearing b7 produces and moves axially under the effect of thrust, eliminate the axial internal clearance of bearing a3 and bearing b7, make the point of contact angle of steel ball and bearing race reach the wrapping angle of design.This device is loaded the position be connected with lathe, housing 4 is fixed, and by the hydraulic control of lathe, drives rotating shaft 1 to rotate, thus realizes the smooth rotation of the relative housing 4 of rotating shaft 1.Bearing 3a and bearing 7b plays supporting revolving shaft 1, guide the effect of rotary motion, it reduces the sliding friction that original device causes owing to being slidably matched greatly, reduce the wearing and tearing that mechanical part causes due to friction, more substantially the kinematic accuracy stopping to cause due to contact wearing and tearing is lost, thus substantially increases the dressing accuracy of emery wheel.
Part not in the detailed description of the invention is prior art.
