Description
Technical field
The present invention relates to a kind of bevel gear excircle clamp for machining, and can be widely applied to tooth form, outer circle and end face has position degree
It is required that bevel gear work piece manufacturing process in.
Background technique
Bevel gear work piece built in auto gearbox is a kind of transmission parts for being directly used in transfer of torque, adds
Working medium amount directly affects vehicle vibration and noise index.Since driving comfort can be the important performance assessment criteria for examining car, therefore
There is very stringent quality requirement to the matched transmission parts quality of automatic transmission.Bevel gear work piece is in sleeve pipe structure, and
One end is equipped with outer cone tooth, and inner hole is equipped with internal spline, and outer circle has relative size, shape and precision with respect to outer cone tooth and internal spline
It is required that design requirement is far not achieved with conventional fixture processing.Processing efficiency is influenced, working hour is increased, reduces yield rate, such as
This necessarily will increase entreprise cost, reduce benefit.
Summary of the invention
The purpose of the present invention is to provide a kind of accurate positioning, structure it is simple, it is easily manufactured, applied widely, to bore tooth
It takes turns workpiece tooth shape locating, the outer circle of machining of bevel gears workpiece and end face, guarantee that bevel gear work piece position degree requires, improves processing matter
Amount, the bevel gear excircle clamp for machining for improving work efficiency, eliminating safe hidden trouble.
In order to achieve the above object, bevel gear excircle clamp for machining of the present invention, including with cone tooth tooth mould end face positioning disk,
The step mandrel for boring tooth tooth mould Internal hole positioning axis, open washer locating shaft, connection screw thread and both ends centre bore, is mounted on step
The cone tooth tooth mould of inner hole is positioned and had on mandrel and by cone tooth tooth mould end face positioning disk, cone tooth tooth mould Internal hole positioning axis, is covered
On step mandrel and with the identical bevel gear work piece contacted of the cone tooth of cone tooth tooth mould, be sleeved on step mandrel, by
Open washer locating shaft positions and abuts the open washer of bevel gear work piece terminal surface installation, by cone tooth tooth mould, bevel gear work piece and opens
The fastening nut that mouth pad is fastened on step mandrel.
Cone tooth tooth on bevel gear excircle clamp for machining of the present invention, the cone tooth tooth mould, inner hole and step mandrel
The outer circle that mould Internal hole positioning axis matches is interference fit positioning；The cone tooth tooth mould, end face is by cone tooth tooth mould end face
Positioning disk positioning, under Dual positioning effect, accurate positioning.
Bevel gear excircle clamp for machining of the present invention, its working principle is that: when work, bevel gear work piece tooth form and cone tooth tooth mould
Tooth shape locating, open washer are placed on bevel gear work piece end face, and fastening nut compresses open washer, to compress bevel gear work piece.So
Afterwards, two centre bores on step mandrel are matched with top contact of two on lathe, realize that positioning clamps.Machine tool chief axis rotation
Movement realizes the processing of outer circle, end face to drive bevel gear work piece rotary motion.After work pieces process is complete, release is top, so
After unclamp fastening nut, unload open washer, then remove workpiece.
Bevel gear excircle clamp for machining of the present invention, structure is simple, easily manufactured, applied widely, as long as lathe is with top
Point can all be applied.It can be used to the other parts that turning, grinding, gear hobbing and bevel gear work piece tooth form have position degree requirement.
Bevel gear excircle clamp for machining of the present invention, for having top lathe, top with lathe holds out against step
Two centre bores at mandrel both ends, with bevel gear work piece tooth shape locating, the outer circle of machining of bevel gears workpiece, end face ensure that cone tooth
Take turns the position degree requirement of workpiece tooth form and outer circle, end face.
Bevel gear excircle clamp for machining of the present invention, because of accurate positioning after workpiece installation, reduce it is unnecessary to knife between process,
Raising processing quality is not only improved, is also beneficial to improve work efficiency, eliminate safe hidden trouble.
In conclusion bevel gear excircle clamp for machining of the present invention, accurate positioning, structure is simple, easily manufactured, the scope of application
Extensively, with bevel gear work piece tooth shape locating, the outer circle of machining of bevel gears workpiece and end face, guarantee the requirement of bevel gear work piece position degree,
Processing quality is improved, work efficiency is improved, eliminates safe hidden trouble.
Detailed description of the invention
Below in conjunction with attached drawing and embodiment, the present invention will be further explained.
Fig. 1 is the structural schematic diagram when present invention clamps workpiece；
Fig. 2 is the step core shaft structure schematic diagram in Fig. 1；
Fig. 3 is the cone tooth tooth mode structure schematic diagram in Fig. 1；
Fig. 4 is the bevel gear work piece structural schematic diagram in Fig. 1.
Specific embodiment
In FIG. 1 to FIG. 4, bevel gear excircle clamp for machining of the present invention, including with cone tooth tooth mould end face positioning disk a, cone
The step mandrel 1 of tooth tooth mould Internal hole positioning axis b, open washer locating shaft c, connection screw thread d and both ends centre bore d, are mounted on platform
It positions on stepwise mandrel and by cone tooth tooth mould end face positioning disk a, cone tooth tooth mould Internal hole positioning axis b and has the cone tooth tooth of inner hole
Mould 2, be sleeved on step mandrel and with the identical bevel gear work piece 3 contacted of the cone tooth of cone tooth tooth mould, be sleeved on step core
On axis, the open washer 4 that bevel gear work piece terminal surface is installed is positioned by open washer locating shaft c and abutted, tooth tooth mould, bevel gear will be bored
Workpiece and open washer are fastened on the fastening nut 5 on step mandrel.
In addition, in figure, the top e of lathe, the machined surface f of bevel gear work piece arrow meaning, bevel gear work piece teeth portion datum level
g。
Bevel gear excircle clamp for machining of the present invention, the foregoing is only a preferred embodiment of the present invention, but this hair
