Abstract

The invention discloses a bevel gear pitch circle positioning adjustable structure which is jointly formed by a base, positioning pins and nuts. Each positioning pin is a ball head pin and is provided with external threads, matched with the nut, at the tail part. Counter bores are uniformly distributed in the edge of the end surface of the base of which the end surface is also provided with 2-3 paths of radially and alternatively arrayed concentric arc slots with the included angles alpha of 280-320 degrees, one path of radial straight slot is arranged in the middle of the rest end surfaces between two ends of the concentric arc slots. The concentric arc slots and the straight slot are T-shaped slots having the same specification and penetrating through the end surface of the base; 3-4 positioning pins are equally inserted in the same concentric arc slot; one positioning pin is inserted in the straight slot. During primary machining, after the positioning pins are positioned by the pitch circles of standard pieces of a machined bevel gear, the nuts are locked to position the positioning pins to form the pitch circle positioning structure of the machined bevel gear. The bevel gear pitch circle positioning adjustable structure cam meet the demand on the pitch circle positioning of the bevel gears with different tooth number and different modulus, and is particularly suitable for matching with small-batch production enterprises with multi-variety production modes.

Description

Bevel gear pitch circle location adjustable structure
Technical field
The present invention relates to a kind of structure with bevel gear pitch circle location, specifically, the present invention relates to a kind of bevel gear pitch circle location adjustable structure.
Background technology
Bevel gear is special because of shape, and particularly undersized bevel gear, when machined end face and endoporus, exists the problems such as location is difficult, clamping is difficult.The industry adopts conventionally with bevel gear pitch circle location structure, is separately aided with clamping device and realizes location and installation, and this fixed location structure is simple, accurate positioning, can meet mach positioning requirements.For the enterprise producing in enormous quantities, fixed location structure is more conducive to the stable of the quality of production.For some production forms, be the medium-sized and small enterprises of the many kinds of small lot, need the location structure of supporting respective numbers could meet production, although so way can realize production, must increase manufacturing cost and production cycle.
Summary of the invention
The present invention is mainly for the deficiencies in the prior art, propose a kind of simple in structure, position is adjustable, the bevel gear pitch circle of accurate positioning location adjustable structure.This location structure meets the bevel gear pitch circle location of different size within the scope of certain size, greatly facilitates user group to produce, and saves production cost.
The present invention is achieved through the following technical solutions technical goal.
Bevel gear pitch circle location adjustable structure, it consists of jointly base, alignment pin and nut.Described alignment pin is ball stud, and afterbody is provided with the external screw thread coordinating with nut.Its improvements are: described base is circular slab, and end surface side is along uniform counterbore, are also provided with radially angle α=280 alternately, 2～3 roads on end face 0～320 0isocentric circular arc groove, between the two ends of isocentric circular arc groove, remain end face middle part and be provided with together radially vertical bar groove, isocentric circular arc groove and vertical bar groove are same specification and run through the T-slot of base end face, in same isocentric circular arc groove, wait 3～4 alignment pins of add-drop, alignment pin of plug-in mounting in vertical bar groove, alignment pin is behind the standard component pitch circle location of processed bevel gear, and locking nut forms the pitch circle location structure of being done processed bevel gear by alignment pin.
The present invention compared with prior art, has following good effect:
1, alignment pin is located along same isocentric circular arc groove, and the bevel gear that this kind of adjustable positioning structure meets the different numbers of teeth or different moduluses within the scope of certain size is located with pitch circle, is particularly suitable for Multi-varieties and Small-batch Production enterprise supporting.Application the present invention can save manufacturing expense, shortens the production cycle;
2, with the standard component pitch circle of bevel gear to be processed, determine alignment pin position, centering is easy, accurate positioning.
Accompanying drawing explanation
Fig. 1 is structural profile schematic diagram of the present invention.
Fig. 2 is the right view of Fig. 1.
Fig. 3 is the embodiment stereogram that the present invention does bevel gear pitch circle location.
Fig. 4 is the upward view of Fig. 3.
The specific embodiment
The invention will be further described with reference to the accompanying drawings below.
Bevel gear pitch circle location adjustable structure shown in Fig. 1, it consists of jointly base 1, alignment pin 2 and nut 3.Described alignment pin 2 is ball stud, and bulb directly coordinates with cone tooth, and alignment pin 2 afterbodys are provided with the external screw thread coordinating with nut 3.Described base 1 is illustrated in figure 2 circular slab, and it is main component.Base 1 end surface side is along uniform 4 counterbores 1.3, and counterbore 1.3 is for connecting the ring flange of lathe.Embodiment is as shown in Figure 3 and Figure 4 for location and installation Designing Passenger Car Differentials bevel gear, because of workpiece size little, therefore on base 1 end face, be provided with 3 roads alternately angle be 300 0isocentric circular arc groove 1.1, between the two ends of concentric circles board slot 1.1, remain end face middle part and be provided with together radially vertical bar groove 1.2, isocentric circular arc groove 1.1 and vertical bar groove 1.2 are same specification and run through the T-slot of base 1 end face.Bevel gear size in the present embodiment and middle isocentric circular arc 1.1 sizes are close, therefore interior 4 alignment pins 2 of add-drop, the alignment pin 2 of the interior plug-in mounting of vertical bar groove 1.2 of waiting of isocentric circular arc groove 1.1 in the middle of being chosen in.Above-mentioned 5 alignment pins 2 are only at the medium add-drop of same circle, and not locking, adds man-hour for the first time temporarily, and pin 2 to be positioned, after the standard component of processed bevel gear is done pitch circle location, just can screw nut 3 and do alignment pin 2 location.On the alignment pin 2 of determining position, processed bevel gear is installed, can accurately obtains the location structure with pitch circle location.
In the present invention, alignment pin 2 is located along same isocentric circular arc groove 1.1, this kind of adjustable positioning structure, and the bevel gear that can meet the different numbers of teeth or different moduluses within the scope of certain size is located with pitch circle, is particularly suitable for Multi-varieties and Small-batch Production enterprise supporting.Application invention can be saved the expense of manufacturing fixture, shortens the production cycle.
