Abstract
The invention discloses an expanding-sleeve gear-grinding mandrel fixture. The expanding-sleeve gear-grinding mandrel fixture is characterized by comprising a gear-grinding mandrel, a separating nut, an expanding sleeve, a gland and a fastening nut, wherein the gear-grinding mandrel is a stepped cylinder with steps; a mounting part is arranged on one side of one step; threads are formed in the step with the mounting part and are matched with the separating nut; a workpiece, the gland and the fastening nut are sequentially arranged on the other side of the steps; the workpiece is mounted on the gear-grinding mandrel through a workpiece inner hole; the expanding sleeve is arranged between the workpiece inner hole and the gear-grinding mandrel; the gland is of a cover-shaped structure, an opening is formed in the lower end of the gland, and a central hole matched with the gear-grinding mandrel is formed in the upper end of the gland; the workpiece is pressed by the gland; the gland is pressed by the fastening nut through threads formed in the gear-grinding mandrel. The expanding-sleeve gear-grinding mandrel fixture has the advantages that the expanding sleeve is adopted to realize positioning; the end surface of a gear is clamped tightly, the inner hole fit clearance of the gear is eliminated, the cutting force generated by a gear shaving tool during reciprocating movement is also overcome, and the precision of the gear is improved; parts adopted by the fixture are common parts used in machining, the fixture is simple to machine and manufacture, and the machining cost is reduced.
Description
Technical field
The design relates to a kind of expansion sleeve type grinding teeth core shaft fixture, belongs to machining technique field.
Background technology
In production, most of gear grinding clamp is all the positioning core axle adopting matched in clearance, but due to the fit clearance of mandrel and gear hole, add cog positioning end surface jitter and the jumping of fixture step end, cause gear to coordinate benchmark relatively to process axis of rotation crooked, produce geometric eccentricity.Strengthen the circular pitch error of workpiece, make again workpiece produce new circular runout and tooth alignment error, often can not get the gear of degree of precision.For this reason, take ringfeder to locate, gear face clamps, and both can eliminate bore fit clearance, and can overcome again shaving cutter and move back and forth the cutting force brought, and makes the accuracy of gear improve l mono-2 grades.
Summary of the invention
For above-mentioned requirements, the object of the design is to provide a kind of expansion sleeve type grinding teeth core shaft fixture, improves Workpiece Machining Accuracy.
For achieving the above object, the design is realized by following technological means:
A kind of expansion sleeve type grinding teeth core shaft fixture, it is characterized in that: comprise roll flute mandrel, block nut, expansion sleeve, gland, clamp nut, described roll flute mandrel is stepped cylindrical with the level, step while be installation portion, step is provided with screw thread and block nut screw connection, the another side of step is provided with workpiece successively, gland, clamp nut, workpiece is arranged on roll flute mandrel by inner hole of workpiece, expansion sleeve is provided with between inner hole of workpiece and roll flute mandrel, described gland is lower ending opening, upper end is provided with the lid-like of the centre bore coordinated with roll flute mandrel, gland workpiece pressing, described clamp nut compresses gland by the screw thread be located on roll flute mandrel.
Further:
Described a kind of expansion sleeve type grinding teeth core shaft fixture, is characterized in that: described block nut is locking nut.
