Description

A kind of expansion sleeve type grinding teeth core shaft fixture
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.
Described a kind of expansion sleeve type grinding teeth core shaft fixture, is characterized in that: described workpiece is splined hole gear.
Described a kind of expansion sleeve type grinding teeth core shaft fixture, is characterized in that: described roll flute mandrel length is 220mm.
Described a kind of expansion sleeve type grinding teeth core shaft fixture, is characterized in that: described roll flute axle diameter is 20mm.
Described a kind of expansion sleeve type grinding teeth core shaft fixture, is characterized in that: described roll flute mandrel installation portion length is 90mm.
The invention has the beneficial effects as follows: the design takes expansion sleeve 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 improves and makes the accuracy of gear; The parts adopted are machined common components, and fixture processing and manufacturing is simple, cuts down finished cost.
Accompanying drawing explanation
Fig. 1 is the design's structural representation.
The implication of drawing reference numeral is as follows: 1 roll flute mandrel, 2 block nuts, 3 expansion sleeves, 4 glands, 5 clamp nuts, 6 workpiece.
Detailed description of the invention
Below in conjunction with Figure of description, design is further described.
As shown in Figure 1, a kind of expansion sleeve type grinding teeth core shaft fixture, it is characterized in that: comprise roll flute mandrel 1, block nut 2, expansion sleeve 3, gland 4, clamp nut 5, described roll flute mandrel 1 is stepped cylindrical with the level, step while be installation portion, step is provided with screw thread and coordinates with block nut 2, the another side of step is provided with workpiece 6 successively, gland 4, clamp nut 5, workpiece 6 is arranged on roll flute mandrel 1 by inner hole of workpiece, expansion sleeve 3 is provided with between inner hole of workpiece and roll flute mandrel 1, described gland 4 is lower ending opening, upper end is provided with the lid-like of the centre bore coordinated with roll flute mandrel 1, gland 4 workpiece pressing 6, described clamp nut 5 compresses gland 4 by the screw thread be located on roll flute mandrel 1.
The parts that the expansion sleeve 3 of the design, block nut 2, expansion sleeve 3, gland 4, clamp nut 5 adopt machined conventional, manufacture processing simple, clamping is easy, can be effectively cost-saving.
Further:
Described a kind of expansion sleeve type grinding teeth core shaft fixture, is characterized in that: described block nut 2 is locking nut.
