Abstract
The invention discloses a bearing inner ring channel super grinder positioning device. The device comprises an advance and retreat brake part and a conical surface body, the lower end of the conical surface body is fixedly connected with the advance and retreat brake part through a connection element, the conical surface of the conical surface body is provided with multiple convex alloy positioning pressing heads in an embedded mode, the middle of the advance and retreat brake part is provided with a brake part bearing, and the lower end of the advance and retreat brake part is provided with multiple brake connection screw holes. The device overcomes the defects in the prior art and is reasonable in design and structure, one advance and retreat brake part is used and is provided with a connector to be connected with the conical surface embedded with alloy, alloy is embedded in an upper inclined face which serves as a workpiece positioning face, the inner chamfer of the inner ring of the workpiece positioning face is a positioning standard, quality of other fine machined surfaces of the workpieces is effectively protected, workpieces of various types do not need to be replaced and adjusted in machining, work efficiency is improved and cost is lowered.
Description
Technical field
The present invention relates to bearing machining equipment technical field, specifically belong 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.
Summary of the invention
The object of this invention is 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 used in the present invention 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, beneficial effect of the present invention is as follows:
The present invention designs 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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is Fig. 1 sectional structure schematic diagram.
The specific embodiment
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.
