Abstract
The utility model discloses a novel high-precision fixture for grinding a splined hole gear. The fixture comprises a core shaft, a spline gear and an expansion sleeve, wherein the expansion sleeve is a housing with a tapered interior; the exterior of the core shaft is tapered; the expansion sleeve is in accordance with the core shaft in taper proportion; the spline gear is fixed on the core shaft; and the expansion sleeve is sleeved on the core shaft and pressed into a gear hole of the spline gear. The fixture adopts a tapered expansion sleeve type core rod, overcomes defects in pore diameter, and can effective ensures the factors required in gear processing, such as the radial runout of a gear ring, profile tolerance of gear teeth, tooth alignment tolerance and the like.
Description
Technical field
The utility model relates to the gear anchor clamps, particularly a kind of anchor clamps of high accuracy splined hole gear grinding.
Background technology
The splined hole gear is accounting for very important effect all the time in gear drive, enjoy favor, because the splined hole gear drive can obtain higher guidance quality, interchangeability and can play self centering effect.Spline connects travelling gear mainly by the cooperation of two splines, and is not too high for the endoporus dimensional requirement of spline gear, and the margin of tolerance is bigger, so it is very big with the operation influence of endoporus location processing to the road, back, need be according to the endoporus size separation, classification is handled, for example roll flute etc.Roll flute requires naturally can be very high, all very important as key elements such as the profile of tooth tolerance of roll flute, teeth directional tolerance, gear ring circular runouts, as shown in fig. 1 the position prior art anchor clamps, spline gear directly is enclosed within on the mandrel, be easy to generate beat loosening etc., and can not guarantee certainly that for the roll flute plug of the bigger gear routine of a kind of like this endoporus dimensional tolerance of splined hole this just makes troubles to the splined hole gear grinding.
Summary of the invention
In order to address the above problem, the utility model provides a kind of novel high-precision splined hole gear grinding anchor clamps, adopt tapering expansion sleeve type plug, remedy the defective in aperture, can also effectively guarantee the key element that Gear Processing such as gear-wheel gear-ring circular runout, form of gear tooth tolerance, teeth directional tolerance will guarantee.
A kind of novel high-precision splined hole gear grinding anchor clamps comprise mandrel, spline gear and expansion set, and described expansion set is the inner sheath body that tapering is arranged, and there is tapering described mandrel outside, and the tapering ratio of described expansion set and mandrel is consistent.
Described spline gear is fixed on the mandrel, and described expansion set is enclosed within on the mandrel, expansion set is compressed into the gear hole of spline gear.
The beneficial effects of the utility model are: adopt tapering expansion sleeve type plug, remedied the defective in aperture, also do not need to do the classification plug according to the aperture sorting simultaneously, saved raw material; Effectively guarantee the key element that Gear Processing such as gear-wheel gear-ring circular runout, form of gear tooth tolerance, teeth directional tolerance will guarantee.
Description of drawings
Fig. 1 is the roll flute clamp structure schematic diagram of prior art;
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Be illustrated in figure 2 as structural representation of the present utility model, a kind of novel high-precision splined hole gear grinding anchor clamps comprise mandrel 1, spline gear 3, expansion set 2, and described expansion set 2 is the inner sheath body that tapering is arranged.
There is tapering described mandrel 1 outside, and the tapering ratio of described expansion set 1 and mandrel 2 is consistent;
Described spline gear 3 is fixed on the mandrel 1, and described expansion set 2 is enclosed within on the mandrel 1, expansion set 2 is compressed into the gear hole of spline gear 3.
Like this in the roll flute process, avoid in the prior art between flower gear to move radially easily or the loosening margin of tolerance that causes that waits excessive, the inconsistent and defective that can't process with roll flute plug roll flute of aperture size.Simultaneously described spline gear 3 is fixed on the mandrel 1, described expansion set 2 is enclosed within on the mandrel 1, and expansion set 2 is consistent with mandrel 1 taper ratio, by fastening nut expansion set 2 is compressed into spline gear 3 holes, compresses to get final product.
Above-mentioned demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.The utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
1. novel high-precision splined hole gear grinding anchor clamps, comprise mandrel, spline gear, it is characterized in that, also comprise expansion set, described expansion set is the inner sheath body that tapering is arranged, and there is tapering described mandrel outside, and described spline gear is fixed on the mandrel, described expansion set is enclosed within on the mandrel, expansion set is compressed into the gear hole of spline gear.
2. a kind of novel high-precision splined hole gear grinding anchor clamps according to claim 1 is characterized in that the tapering ratio of described expansion set and mandrel is consistent.
