Description
Technical field
The utility model relates to a kind of vehicle clamper, and specifically, the utility model relates to a kind of bevel planet gear flank of tooth location lathe finish fixture that is used for the processing automobile gearbox.
Background technology
The only hundreds of grams of bevel planet gear weight in the automobile gearbox, and the another side of the flank of tooth is a sphere.Special because of this gear shape and structure, the machined difficulty is big, and the industry adopts the first precision forging flank of tooth usually, remakes the processing of endoporus and spherical turning then.Prior art clamps the Vehicle Processing endoporus with tooth portion location earlier, uses the mandrel location endoporus that expands again instead and realizes spherical turning processing.This kind simple and convenient processing method can effectively be organized production.But this processing method work efficiency is low, is not suitable for the numerically controlled lathe batch machining.In addition, the positioning reference of multiple clamping is different, causes a certain amount of accumulated error, must increase product rotational noise and uneven wear.
The utility model content
The utility model is primarily aimed at the deficiency of prior art; Propose a kind of simple in structure, accurate positioning, clamping quick, just can realize that through clamping the bevel planet gear flank of tooth of endoporus and spherical turning processing locatees lathe finish fixture, it is supporting that these anchor clamps are particularly suitable for numerically controlled lathe.
The utility model is realized technical goal through following technical proposals.
Bevel planet gear flank of tooth location lathe finish fixture, it is made up of location structure and axial locking structure jointly.Said location structure comprises coaxial flange connecting, terminal pad, main body, and pressing plate, mandrel and tooth mould.Said mandrel is a reference axial direction positioning tooth mould with the main body endoporus, and the pressing plate that is connected on the main body end face is locked the tooth mould.Said axial locking structure is the linkage lever mechanism that is located in the location structure, and it comprises jaw, connecting rod, pin, axle sleeve, wing plate, connects cover and screw rod.The said cover that connects is for the axially-movable member, and it and terminal pad endoporus matched in clearance are located to connect and overlap screw rod that endoporus stretches out outwardly for outreaching part.Said axle sleeve is horizontally-arranged T shape member; Its big end inner side end is that sphere cooperates 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, and every five equilibrium middle part radially notch is hinged with connecting rod one end of axially installing, and tiltedly curved connecting rod stage casing is provided with the guide rail elongated slot of an easement; The pin that is fixedly mounted on the main body cooperates with the guide rail elongated slot, and the jaw that axle sleeve axial action drivening rod is connected with the outer end is to location workpiece axial locking or loosening up.
The utility model compared with prior art has following good effect:
1, tooth mould location and axial locking integral structure are rationally distributed, compact;
2, workpiece accomplishes that machining benchmark and design basis are unified, accurate positioning, quick for installation with tooth and tooth mould location;
3, the motion-promotion force of axial locking structure is introduced by screw rod, and this interface is fit to connection and surges or pneumatic mechanism, and main supporting numerically controlled lathe helps producing in batches.
Description of drawings
Fig. 1 is the utility model structural profile sketch map.
Fig. 2 is the right view of Fig. 1.
The specific embodiment
According to accompanying drawing the utility model is described further below.
A kind of bevel planet gear flank of tooth location lathe finish fixture shown in Figure 1, it is made up of location structure and axial locking structure jointly.Said location structure comprises coaxial flange connecting 1, terminal pad 2, main body 3, and pressing plate 4, mandrel 5 and tooth mould 6.Said mandrel 5 is two nodal axisn structures, and it is a reference axial direction positioning tooth mould 6 with main body 3 endoporus.Be connected pressing plate 4 on main body 3 end faces with tooth mould 6 locking, main body 3 is through seam and terminal pad 2 coaxial positioning and connect.Said axial locking structure is the linkage lever mechanism that is located in the location structure, and it comprises jaw 7, connecting rod 8, pin 9, axle sleeve 10, wing plate 11, connects cover 12 and screw rod 13.The said cover 2 that connects is for 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 screw rod 13 stretches out towards the right side among Fig. 1.Present embodiment is installed on the spindle of numerical control lathe, and screw rod 13 is connected with push rod in the main shaft endoporus introduces the power of impeller-hub to locking mechanism.Said axle sleeve 10 is horizontally-arranged T shape member, and its big end inner side end is that sphere cooperates 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 bent limit of trisection; Every five equilibrium 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 that is fixedly mounted on the main body 3 cooperates with the guide rail elongated slot, and 7 pairs of location of the jaw that axle sleeve 2 axial action drivening rods 8 are connected with outer end workpiece spindle is to clamping or loosening up.
