Abstract
The utility model discloses a positioning device of a super-lapping machine for bearing inner-ring raceways. The positioning device comprises an advancing and backing brake part and a conical surface member. The lower end of the conical surface member is fixedly connected with the advancing and backing brake part through a connector. A plurality of protruding positioning alloy press heads are inlaid in the conical surface of the conical surface member. A brake part bearing is arranged in the middle of the advancing and backing brake part, and a plurality of brake part connecting screw holes are formed in the lower end of the advancing and backing brake part. The positioning device overcomes defects of the prior art and is reasonable in structural design. Since the advancing and backing brake part is integrally connected with the conical surface inlaid with alloy through the connector, the upper alloy-inlaid bevel surface serves as a workpiece positioning surface, inner chamfers of inner rings on the workpiece positioning surface are taken as positioning references, and quality of other fine-processed surfaces of workpieces is guaranteed effectively. When in processing of different type of workpieces, changing and adjusting are omitted, and work efficiency is improved while cost is lowered.
Description
Technical field
The utility model relates to bearing machining equipment technical field, specifically belongs to the super machine positioning device that grinds of bearing inner race raceway groove.
Background technology
Bearing inner race is the main workpiece of bearing, and bear inner ring grooved railway is super, to grind operation processing be significant points, and its location in process plays conclusive effect to product quality.Equipment manufacturing compresses with the centering of axostylus axostyle endoporus and end face bearing pinch roller, adjusts inconvenience, and end face and bore area scratch, and service life is short, has increased entreprise cost.
Utility model content
The purpose of this utility model has been to provide the super machine positioning device that grinds of bearing inner race raceway groove; the deficiencies in the prior art are overcome; project organization is reasonable; stay moving part by advance and retreat; staying on moving part has a connector and the edge alloy conical surface to be connected as a single entity; inclined-plane, top edge alloy is workpiece locating surface, and in the inner ring of workpiece locating surface, chamfering is positioning datum, effectively protects the quality of other polished surface of workpiece.The processing of polytypic workpiece does not need to change and adjusts, and operating efficiency raising reduces costs.
The technical solution adopted in the utility model is as follows:
The super machine positioning device that grinds of bearing inner race raceway groove, this described device comprises that advance and retreat are in moving part and taper seat body, taper seat body lower end is stayed moving part by connector and advance and retreat and is fixedly connected with, on the taper seat of described taper seat body, be installed with the alloy location pressure head of multiple projections, described advance and retreat centre position in moving part is provided with bearing in moving part, and bottom is provided with multiple connecting screw holes in moving part.
Described alloy location pressure head is four and is uniformly distributed, and alloy location pressure head is strip structure from top to bottom.
Described advance and retreat bottom in moving part is provided with four connecting screw holes in moving part.
Described connector bottom has will advance and retreat upper end in moving part parcel of draw-in groove, connector lower surface with advance and retreat between upper surface in moving part, be bolted fixing.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model design cone carbide inserts, be arranged on radial rotary axle, described cone assembly on the same axial line of workpiece, the location basal plane of described workpiece be realize at the fillet surface of workpiece, described workpiece motion s is to do longitudinal advance and retreat by hydraulic power.Adopt after technique scheme, by cone assembly and workpiece synchronous rotary, cone carbide inserts face contacts location with chamfering work piece face, effectively protects the quality of other polished surface of workpiece, reduces costs.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is Fig. 1 sectional structure schematic diagram.
Detailed description of the invention
Referring to accompanying drawing, the super machine positioning device that grinds of bearing inner race raceway groove, this device comprises that advance and retreat are in moving part 1 and taper seat body 2, taper seat body 2 lower ends are stayed moving part 1 by connector 3 and advance and retreat and are fixedly connected with, connector 3 bottoms have draw-in groove 301 will advance and retreat in moving part 1 upper end parcel, and connector 3 lower surfaces and advance and retreat are fixing in being bolted between moving part 1 upper surface.On the taper seat of taper seat body, be installed with the alloy location pressure head 201 of multiple projections, alloy location pressure head is four and is uniformly distributed, and alloy location pressure head is strip structure from top to bottom.Advance and retreat centre position in moving part is provided with bearing in moving part 4, and bottom is provided with four connecting screw holes in moving part 101.Cone carbide inserts, is arranged on radial rotary axle, described cone assembly on the same axial line of workpiece, the location basal plane of described workpiece be realize at the fillet surface of workpiece, described workpiece motion s is to do longitudinal advance and retreat by hydraulic power.By cone assembly and workpiece synchronous rotary, cone carbide inserts face contacts location with chamfering work piece face, effectively protects the quality of other polished surface of workpiece, reduces costs.
