Technical field
The present invention relates to a kind of gear positioning clamp field, particularly to a kind of duplicate gear positioning and centralizer.
Background technology
In prior art, positioning during the following process to duplicate gear, is all often only to be carried out with gear wheel Positioning, when ensureing the position relationship of gear wheel and little gear, to be found out the specific teeth groove of gear wheel and to enter by naked eyes Row positioning, but this positioning mode only by perusal, accuracy is not high, processes and later also needs to test Whether the teeth groove to confirm selected is correct.Another method be by universal tool microscope (a kind of instrument) to look for the teeth groove of gear wheel Lai Positioned, but this centering mode efficiency is too low, does not possess the ability of batch production.
Content of the invention
In view of this, the technical problem to be solved is to provide a kind of duplicate gear positioning and centralizer, its Can effectively improve while duplicate gear machining accuracy it is also possible to reduce difficulty of processing, improve working (machining) efficiency.
The present invention is achieved through the following technical solutions:
A kind of duplicate gear positioning that the present invention provides and centralizer include for be set with duplicate gear mandrel, setting On mandrel and compress the securing member of duplicate gear and for locking the positioner of duplicate gear;Described positioner mainly by Gear wheel spacer and little gear spacer composition, described gear wheel spacer and little gear spacer are detachably connected, described Mandrel is provided with boss, and described positioner is arranged on boss and is tightened together with boss.
Further, described gear wheel spacer and little gear spacer are equipped with for the hole through duplicate gear, institute State and the positioning tooth being meshed with duplicate gear is provided with hole or is fitted with the locating taper pin matching with duplicate gear teeth groove.
Further, it is evenly arranged with three groups of positioning tooths in described gear wheel spacer.
Further, it is provided with one group of positioning tooth in described little gear spacer.
Further, it is provided with the bearing pin for being mutually positioned between described gear wheel spacer and little gear spacer.
Further, described gear wheel spacer and little gear spacer are designed with positioning plane.
Further, described duplicate gear positioning and centralizer also include axially position block, described axially position block setting On little gear spacer and be located at gear wheel spacer center in the hole.
The beneficial effects of the present invention is: the boss on mandrel of the present invention is respectively provided with and little gear spacer and little tooth The connecting hole that wheel spacer is connected, can be connected with large and small gear spacer, respectively using one of little gear spacer Teeth groove need to ensure a specific position relationship, three teeth groove of its gear wheel spacer with three teeth groove of gear wheel spacer Remove outside the angle ensureing part, be also equipped with certralizing ability, make geometric center and the center of rotation weight of part by pin-and-hole positioning Close, keep ad-hoc location by arranging directly flat, pin-and-hole and internal tooth, before processing, can easily and fast, accurately find out two gears Between position relationship, follow-up processing directly can be carried out on this fixture, and exchanging by positioner afterwards, also can Realize the processing at duplicate gear two ends, the positioning in large and small gear spacer in apparatus of the present invention are carried out on this fixture simultaneously The purpose that mode is set to taper pin is to eliminate transverse tooth thickness between different gears poor (generally 0.005mm about), ensure permissible While realizing quick positioning, can also effectively adapt to the duplicate gear of different flank profil processing technique, realize batch production.

Specific embodiment
Hereinafter with reference to accompanying drawing, the preferred embodiments of the present invention are described in detail.It should be appreciated that preferred embodiment Only for the present invention is described, rather than in order to limit the scope of the invention.
A kind of duplicate gear of present invention positioning and centering frock, including the mandrel 1 for being set with duplicate gear, are arranged on core On axle 1 and compress the securing member 9 of duplicate gear and for locking the positioner of duplicate gear;Described positioner is by canine tooth Wheel spacer 3 and little gear spacer 2 connect composition;Described mandrel is provided with boss, and described positioner is arranged on boss simultaneously Tighten together with boss.
Fig. 1 is the first embodiment of apparatus of the present invention, the positioning tooth of gear wheel spacer centre bore and duplex herein Gear gear wheel positions, and little gear spacer is set to the little gear positioning of locating taper pin and duplicate gear, processes duplicate gear During big end end face, securing member 9 is bolt, and the little gear spacer 2 in positioner is located on the boss of mandrel 1, axially position Block 4 is arranged on little gear spacer 2 and is located in the centre bore 304 of gear wheel spacer 3, and connects with little gear spacer 2 Connect, gear wheel spacer is provided with pin-and-hole 301, little gear spacer is provided with pin-and-hole 201, uniformly sets in gear wheel spacer It is equipped with three groups of positioning tooths 303, the gear wheel of duplicate gear is positioned, three groups of locating taper pins of setting in little gear spacer Hole 203, is positioned to the little gear of duplicate gear by connecting locating taper pin, the pin-and-hole 201 and 301 in two gear sheet is right Should arrange, be connected by bearing pin 8 so that gear wheel spacer and little gear spacer are kept at an angle, duplicate gear is little Gear wheel moves upwards through positioner radial positioning to gear down, and is compressed through mandrel by securing member 9, by setting Positioning plane 202 in the positioning plane 302 and little gear spacer on gear wheel spacer can facilitate enterprising in lathe Row centering.
In the present embodiment, gear wheel spacer can also be the canine tooth by the locating taper pin of setting to duplicate gear Wheel is positioned, and little gear spacer can also by the positioning tooth of setting, the little gear of duplicate gear be positioned, this Skilled person should be appreciated that and this several positioning mode can be combined, thus realizing different positioning modes.A collection of The transverse tooth thickness of part can not possibly be completely the same, and it all exists, and some are poor, the positioning in large and small gear spacer in apparatus of the present invention The purpose that mode is set to taper pin is exactly to eliminate transverse tooth thickness between different gears poor (generally 0.005mm about), can be effective Adapt to the duplicate gear of different flank profil processing technique, realize batch production.
As the another embodiment of apparatus of the present invention, when processing duplicate gear small end end face, big in positioner Gear spacer 3 is connected with the boss of mandrel 1, and axially position block 4 is arranged on little gear spacer 2 and is located at gear wheel positioning The center in the hole of piece 3, and connect with little gear spacer 2, gear wheel passes down through positioner to duplicate gear little gear upward Radial positioning, and compressed through mandrel by securing member 9.
Finally illustrate, above example only in order to technical scheme to be described and unrestricted, although by ginseng According to the preferred embodiments of the present invention, invention has been described, it should be appreciated by those of ordinary skill in the art that can So that in the form and details it is made with various changes, the present invention being limited without departing from appended claims Spirit and scope.
