Detailed description of the invention
Attached drawing 1 is self-centering tooth inserting tooling overall structure diagram；
Attached drawing 2 is self-centering tooth inserting tooling partial, detailed view.
Specific embodiment
The utility model is further described with reference to the accompanying drawing.
A kind of self-centering tooth inserting tooling, as shown in Fig. 1, including centring means 1；The symmetry axis of the centring means 1 with
The rotation center of rotary table top is overlapped；The centring means 1 includes bottom plate 11, rise core 12 and mandrel 13；The bottom plate 11 and rotation
Table with revolvable top is fixedly connected, and is rotated synchronously in Gear Shaping；The core 12 that rises is fixed at 11 top of bottom plate；The core 12 that rises
Outer sheath is equipped with workpiece 8；Mandrel 13 is provided in the core 12 that rises；The open-type conical surface, the core are equipped on the inside of the core 12 that rises
The conical surface, two conical surface snug fits are also equipped on the outside of axis 13；Through-thickness is provided with through-hole on the bottom plate 1；Such as 2 institute of attached drawing
Show, the mandrel 13 passes through through-hole far from 8 one end of workpiece and extends to 1 lower section of bottom plate, is cooperated by external screw thread and nut 14；It is described
14 upper end of nut is close to bottom plate 11, mandrel 13 can be made to be threadedly engaged effect down along length by rotating nuts 14
Direction free extension, so that the conical surface of mandrel 13 be driven to move up and down；When mandrel 13 moves up, two conical surfaces separation, at this time by work
8 sets of part in 12 outside of core of rising；Subsequent rotating nuts 14 drive mandrel 13 to move down, by two conical surfaces compression make to rise core 12 occur it is subtle
Expansion, to complete centering with being close on the inside of workpiece 8；The adjustment process can be realized only by adusting nut 14, compared to biography
The clamping tools such as the chuck mode of system, not only centering precision is high, and adjustment speed is obviously improved.
The self-centering tooth inserting tooling further includes positioning device 2；The positioning device 2 includes supporting element 4 and compressing member 5；
The clamping part of the workpiece 8 is arranged in as shown in the figure between supporting element 4 and compressing member 5；Between several 4 circumferential directions of the supporting element
It every setting in 1 periphery of centring means, is fixedly connected with 11 upper end of bottom plate, the lower end surface pair at supporting element 4 top and workpiece 8
It answers, provides uniform and stable support for workpiece 8；
The compressing member 5 includes hydraulic cylinder 51, pressing plate 52 and pressure head 53；The hydraulic cylinder 51 drives pressing plate 52 to do lifting fortune
It is dynamic；The pressure head 53 is fixed at 52 lower end of pressing plate；53 bottom of pressure head is bonded setting with workpiece 8；Several compressions
Part 5 is corresponding with the position of supporting element 4, and the hydraulic cylinder 51 of each compressing member 5 works asynchronously, after workpiece 8 is completed to feel relieved, operation
Compressing member 5 pushes, it is ensured that 8 position of workpiece is ajusted, and is not shaken during subsequent Gear Shaping, and then improves processing essence
Degree.
The core 12 that rises is with mandrel 13 because cooperate frustoconical bevel angle is identical, and angular range is 5 °~10 °, this
When rise between core 12 and the conical surface of mandrel 13 that friction is small, be not likely to produce abrasion, can significantly extend the use of centring means 1
Service life；If frustoconical bevel angle is too small, need mobile more distance that can just make the to rise degree of deformation that core 12 reaches certain of mandrel 13, thus
It is that the operating time is elongated, is unfavorable for the raising of production efficiency；If frustoconical bevel angle is excessive, rising can be generated between core 12 and mandrel 13
Biggish frictional force not only can make centring means lose precision quickly, and need to frequently replace accessory to increase abrasion, dimension
Shield cost greatly increases.
Cutter 9 is correspondingly arranged on above the workpiece 8, cutter 9 can be freely lifted；After completing centering and positioning, workpiece 8
It is rotated synchronously together with rotary table top with bottom plate 11, Gear Shaping is carried out to workpiece 8 with the cooperation of cutter 9.
The above is only the preferred embodiment of the utility model, it should be pointed out that: for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
