Abstract
The invention discloses a gear shaving clamp which comprises a spindle and a pushing sleeve. The spindle is a stepped spindle with a large-diameter spindle section and a small-diameter spindle section. The small-diameter spindle section is sleeved with the cylindrical pushing sleeve, and the pushing sleeve and the small-diameter spindle section are in basic-hole-system clearance fit. Due to the fact that the pushing sleeve and the small-diameter spindle section are in basic-hole-system clearance fit, the structure is simple, assembling and disassembling are convenient, and production efficiency is improved.
Description
Technical field
The present invention relates to a kind of frock clamp for clamping gear, particularly relate to a kind of gear shaving clamp.
Background technology
In modern mechanical industry, gear is a kind of important component of machine, and motion state and power are transmitted in its effect.There is shaving operation during Gear Processing, after gear is fixedly clamped by general employing fixture, carry out shaving again.Common gear shaving clamp comprises mandrel and top cover, and by geared sleeve on mandrel, the two ends of mandrel are provided with center positioning hole, two of the lathe top center positioning holes holding out against mandrel two ends during use, opens lathe, carries out shaving.This gear shaving clamp realizes feeling relieved by the mode that the cylindrical of mandrel coordinates with bore.
For ease of the two top center positioning holes holding out against mandrel two ends of lathe, top cover must not protrude from end face of mandrel, for ensureing that gear to be processed location is rear coaxial with mandrel, gap must not be there is between top cover and mandrel, general employing interference fit, then top cover is difficult to take off from mandrel, and Fixture for Gear-shaving dismounting inconvenience, affects production efficiency.
Summary of the invention
The object of the invention is to provide the gear shaving clamp that a kind of structure is simple, be convenient to dismounting, enhance productivity.
For achieving the above object, the technical solution used in the present invention is: a kind of gear shaving clamp, comprise mandrel and top cover, described mandrel is the step mandrel being provided with large footpath shaft part and path shaft part, described path shaft part is arranged with columnar described top cover, adopt basic hole system matched in clearance between described top cover and path shaft part, structure is simple, be convenient to dismounting, enhance productivity.
In technique scheme, the two ends of described mandrel are provided with the centre bore adopting and be with the Type B centre drill protecting cone to process, the end face of described path shaft part is axially extended in one end of described top cover, and this end of described top cover is provided with the top suitable conical aperture with lathe, being convenient to the top taper seat of lathe withstands in the pyramid type aperture of top cover extension end face, axial compression gear to be processed.
In technique scheme, geared sleeve to be processed is located on the shaft part of described large footpath, the other end of described top cover is provided with the radial positioning round table extended, the excircle dimension of this positioning round table is greater than the inner circle size of described gear to be processed, avoid gear to be processed to produce axial float in Shaving Process, improve shaving precision and product quality.
Preferably, the excircle dimension of described positioning round table is greater than the inner circle size 20 ~ 30mm of described gear to be processed, i.e. the large 10 ~ 15mm of single side size.
In technique scheme, described large footpath shaft part is provided with spacing round platform away from one end of the shaft shoulder, and the excircle dimension of described positioning round table compares the little 0 ~ 10mm of excircle dimension of described spacing round platform, i.e. the little 0 ~ 5mm of single side size.
Preferably, the excircle dimension of described positioning round table is equal with the excircle dimension of described spacing round platform.
In technique scheme, the side relative with described large footpath shaft part of described spacing round platform is reducing shaft part, and the large footpath section of this reducing shaft part, near described spacing round platform, avoids stress concentrate and shorten the service life of sun gear Fixture for Gear-shaving.
In technique scheme, the outer rim rounding of described large footpath section.
Further technical scheme, described top cover axially extends the end face 30 ~ 45mm of described path shaft part.Fit clearance between described top cover and path shaft part is 0 ~ 0.035mm.
Because technique scheme is used, the advantage that the present invention compared with prior art has is:
1. adopt basic hole system matched in clearance between top cover of the present invention and path shaft part, structure is simple, be convenient to dismounting, enhance productivity.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention one;
Fig. 2 is the front view of step mandrel in embodiment one;
Fig. 3 is the front view of top cover in embodiment one;
Wherein: 1, mandrel; 1a, large footpath shaft part; 1b, path shaft part; 1c, spacing round platform; 1d, large footpath section; 2, top cover; 2a, positioning round table; 3, gear to be processed; 4, lathe is top.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
Embodiment one: shown in Fig. 1 ~ 3, a kind of gear shaving clamp, comprise mandrel 1 and top cover 2, described mandrel 1 is for being provided with the step mandrel of large footpath shaft part 1a and path shaft part 1b, described path shaft part 1b is arranged with columnar described top cover 2, between described top cover 2 and path shaft part 1b, adopts basic hole system matched in clearance.Preferably, the fit clearance between described top cover 2 and path shaft part 1b is 0 ~ 0.035mm.
The two ends of described mandrel 1 are provided with the centre bore 1e adopting and be with the Type B centre drill protecting cone to process, end face 30 ~ the 45mm of described path shaft part 1b is axially extended in one end of described top cover 2, and this end of described top cover 2 is provided with the top 4 suitable conical apertures with lathe, being convenient to the top taper seat of lathe withstands in the pyramid type aperture of top cover extension end face, axial compression gear to be processed.
Gear 3 to be processed is sheathed on described large footpath shaft part 1a, the other end of described top cover 2 is provided with the radial positioning round table 2a extended, the excircle dimension of this positioning round table 2a is greater than the inner circle size 20 ~ 30mm of described gear to be processed 3, the i.e. large 10 ~ 15mm of single side size, avoid gear to be processed to produce axial float in Shaving Process, improve shaving precision and product quality.
