Description
Technical field
The present invention relates to a kind of vehicle clamper, specifically, the present invention relates to a kind of flank of tooth of the bevel planet gear for processing automobile gearbox positioning accurate vehicle clamper.
Background technology
Bevel planet gear weight in automobile gearbox is hundreds of grams only, and the another side of the flank of tooth is sphere.Because of this gear shape and structure special, the machined difficulty is large, the industry adopts the first precision forging flank of tooth usually, then remakes the processing of endoporus and spherical turning.Prior art first clamps the Vehicle Processing endoporus with tooth section location, then uses expansion core axle location endoporus instead and realize spherical turning processing.This kind of simple and convenient processing method, can effectively organize production.But this processing method work efficiency is low, is not suitable for the numerically controlled lathe batch machining.In addition, the positioning datum difference of multiple clamping, cause a certain amount of accumulated error, must increase product rotational noise and uneven wear.
Summary of the invention
The present invention is mainly for the deficiencies in the prior art, propose a kind of simple in structure, accurate positioning, clamping quick, just can realize by clamped one time the bevel planet gear flank of tooth positioning accurate vehicle clamper that endoporus and spherical turning are processed, it is supporting that this fixture is particularly suitable for numerically controlled lathe.
The present invention is achieved through the following technical solutions technical goal.
Bevel planet gear flank of tooth positioning accurate vehicle clamper, it consists of jointly location structure and axial locking structure.Described location structure comprises flange, terminal pad, the main body of coaxial connection, and pressing plate, mandrel and tooth mould.Described mandrel be take the main body endoporus as reference axial direction positioning tooth mould, and the pressing plate be connected on the main body end face is locked the tooth mould.Described axial locking structure is the linkage lever mechanism be located in location structure, and it comprises jaw, connecting rod, pin, axle sleeve, wing plate, female connector and screw rod.Described female connector is the axially-movable member, and it and terminal pad endoporus matched in clearance are located at screw rod that the female connector endoporus stretches out outwardly for outreaching part.Described axle sleeve is horizontally-arranged T shape member, its large end inner side end is that sphere coordinates formation to be hinged with wing plate endoporus, axle sleeve and terminal pad internal thread hole connect and compose the interlock body, the wing edges of boards are along being the bent limit of trisection, every decile middle part radially notch is hinged with connecting rod one end of axially installing, tiltedly curved connecting rod stage casing is provided with the guide rail elongated slot of an easement, the pin be fixedly mounted on main body coordinates with the guide rail elongated slot, and the jaw that axle sleeve axial action drivening rod is connected with outer end is to positioning workpieces axial locking or loosening up.
The present invention compared with prior art, has following good effect:
1, tooth mould location and axial locking integral structure, rationally distributed, compact;
2, workpiece, with tooth and tooth mould location, accomplishes that machining benchmark and design basis are unified, accurate positioning, quick for installation;
3, the motion-promotion force of axial locking structure is introduced by screw rod, and this interface is applicable to connection and surges or pneumatic mechanism, and main supporting numerically controlled lathe is conducive to batch production.
The accompanying drawing explanation
Fig. 1 is structural profile schematic diagram of the present invention.
Fig. 2 is the right view of Fig. 1.
The specific embodiment
Below the invention will be further described with reference to the accompanying drawings.
A kind of bevel planet gear flank of tooth positioning accurate vehicle clamper shown in Fig. 1, it consists of jointly location structure and axial locking structure.Described location structure comprises flange 1, terminal pad 2, the main body 3 of coaxial connection, and pressing plate 4, mandrel 5 and tooth mould 6.Described mandrel 5 is two nodal axisn structures, and it take main body 3 endoporus as reference axial direction positioning tooth mould 6.Be connected to pressing plate 4 on main body 3 end faces by 6 lockings of tooth mould, main body 3 is by seam and terminal pad 2 coaxial positioning and connect.Described axial locking structure is the linkage lever mechanism be located in location structure, and it comprises jaw 7, connecting rod 8, sell 9, axle sleeve 10, wing plate 11, female connector 12 and screw rod 13.Described female connector 2 is the axially-movable member, and it and terminal pad 2 endoporus matched in clearance are located at screw rod 13 that adapter 12 endoporus stretch out outwardly for outreaching part, and in Fig. 1, screw rod 13 stretches out towards the right side.The present embodiment is arranged on spindle of numerical control lathe, and screw rod 13 is connected with the push rod in inner hole of spindle the power of introducing the promotion axial locking structure.Described axle sleeve 10 is horizontally-arranged T shape member, and its large end inner side end is that sphere coordinates formation to be hinged with wing plate 11 endoporus, and axle sleeve 10 connects and composes the interlock body with terminal pad 2 internal thread holes.Wing plate 11 edges embodiment illustrated in fig. 2 are the trisection limit, every decile middle part radially notch is hinged with connecting rod 8 one ends of axially installing, tiltedly curved connecting rod 8 stage casings are provided with the guide rail elongated slot of an easement, the pin 9 be fixedly mounted on main body 3 coordinates with the guide rail elongated slot, 7 pairs of positioning workpieces axial grips of jaw that axle sleeve 2 axial action drivening rods 8 are connected with outer end or loosen moving.
