Abstract
The utility model provides a kind of grinding teeth core shaft fixture, its generally multi-diameter shaft, include thread segment, clamping workpiece section, positioning shaft shoulder, clamping bulb successively from top to bottom, wherein the diameter of thread segment and clamping bulb is less than the diameter of clamping workpiece section and positioning shaft shoulder, and the outer peripheral face of the clamping workpiece section is machined with a plurality of axial groove.In above-mentioned technical proposal, due to being machined with a plurality of axial groove in the outer peripheral face of clamping workpiece section, the contact area between the endoporus of workpiece and roll flute mandrel can thus be reduced, beneficial to clamping, this groove structure can allow mandrel to have enough expansion spaces when heated simultaneously, extruded product endoporus is avoided, so that convenient dismounting.Also, it is machined with a plurality of axial groove in the outer peripheral face of clamping workpiece section, moreover it is possible to mitigate the weight of mandrel to a certain extent.
Description
Technical field
The utility model is related to a kind of grinding teeth core shaft fixture.
Background technology
Its position for being used for clamping workpiece of the roll flute mandrel that prior art is provided is typically designed to cylinder, due to workpiece
Endoporus and roll flute mandrel be that small―gap suture coordinates, contact area between the two is big, and resistance is big, therefore clamping difficulty is larger；Its
Secondary, workpiece is in grinding process, and mandrel is heated to produce enough expansions, so that extruded product endoporus, causes dismounting difficult.Furthermore,
When workpiece belongs to macropore part, the diameter of mandrel is inevitable bigger, and the weight of mandrel will be greatly increased, and the weight of mandrel is added
The weight of workpiece bears workpiece weight limit by directly approach lathe, causes lathe rigidity not enough, thus increase machine bearing,
The loss of driving-chain etc..
Utility model content
The technical problems to be solved in the utility model is to provide a kind of grinding teeth core shaft fixture for being easy to clamping and dismounting workpiece.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of grinding teeth core shaft fixture, its generally rank
Terraced axle, includes thread segment, clamping workpiece section, positioning shaft shoulder, wherein clamping bulb, thread segment and clamping bulb successively from top to bottom
Diameter be less than the diameter of clamping workpiece section and positioning shaft shoulder, the outer peripheral face of clamping workpiece section is machined with a plurality of axial recessed
Groove.
In above-mentioned technical proposal, due to being machined with a plurality of axial groove in the outer peripheral face of clamping workpiece section, thus can
The contact area between the endoporus and roll flute mandrel of workpiece is reduced, beneficial to clamping, while this groove structure can allow mandrel to exist
There are enough expansion spaces when heated, it is to avoid extruded product endoporus, so that convenient dismounting.Also, in the periphery of clamping workpiece section
Face is machined with a plurality of axial groove, moreover it is possible to mitigate the weight of mandrel to a certain extent.
Preferably, the outer peripheral face of the clamping workpiece section is symmetrically machined with the groove of four axial directions, makes clamping workpiece section
Cross section be in cross.
In order to mitigate the weight of mandrel, further, the outer peripheral face of the positioning shaft shoulder is equally symmetrically machined with four
The groove of axial direction, the cross section of the positioning shaft shoulder is equally in cross.
In order to mitigate the weight of mandrel, yet further, the section of the positioning shaft shoulder is in the pyramidal structure stood upside down.
Wherein, the angle of the taper is 54 °.
Brief description of the drawings
Fig. 1 is the roll flute core shaft structure schematic diagram in the utility model embodiment；
Fig. 2 is Fig. 1 schematic top plan view；
Reference is：
1 --- thread segment 2 --- clamping workpiece section
3 --- positioning shaft shoulder 4 --- clamping bulbs.
Embodiment
For the ease of the understanding of those skilled in the art, further is made to the utility model with reference to embodiment and accompanying drawing
Explanation, the content that embodiment is referred to not to it is of the present utility model limit.
In description of the present utility model, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", " length ", " width
Degree ", " thickness ", " on ", " under ", "front", "rear", "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outer ",
The orientation or position relationship of the instructions such as " clockwise ", " counterclockwise " be based on orientation shown in the drawings or position relationship, be only for
It is easy to description the utility model and simplifies describe, rather than to indicate or imply that signified device or element must have specific
Orientation, with specific azimuth configuration and operation, therefore it is not intended that to limitation of the present utility model.
In addition, term " first ", " second " are only used for describing purpose, and it is not intended that indicating or implying relative importance
Or the implicit quantity for indicating indicated technical characteristic.In description of the present utility model, " multiple " be meant that two or
Two or more, unless otherwise specifically defined., it is necessary to illustrate, unless otherwise rule in description of the present utility model
Fixed and restriction, term " installation ", " connected ", " connection " should be interpreted broadly, for example, it may be mechanically connect or electrically connect,
It can be the connection of two element inner segments, can be joined directly together, can also be indirectly connected to by intermediary, for this area
Those of ordinary skill for, the concrete meaning of the term can be understood as the case may be.
As shown in Figure 1, 2, preferred embodiment of the present utility model is：A kind of grinding teeth core shaft fixture, its generally multi-diameter shaft,
Include thread segment 1, clamping workpiece section 2, positioning shaft shoulder 3, wherein clamping bulb 4, thread segment 1 and clamping bulb successively from top to bottom
4 diameter is less than the diameter of clamping workpiece section 2 and positioning shaft shoulder 3, and the outer peripheral face of the clamping workpiece section 2 is machined with a plurality of axial direction
Groove.As preferred technical scheme, the recessed of four axial directions can be symmetrically machined with the outer peripheral face of clamping workpiece section 2
Groove, the cross section for making clamping workpiece section is in cross.
In above-mentioned technical proposal, due to being machined with a plurality of axial groove in the outer peripheral face of clamping workpiece section 2, thus can
The contact area between the endoporus and roll flute mandrel of workpiece is reduced, beneficial to clamping, while this groove structure can allow mandrel to exist
There are enough expansion spaces when heated, it is to avoid extruded product endoporus, so that convenient dismounting.Also, in the periphery of clamping workpiece section 2
Face is machined with a plurality of axial groove, moreover it is possible to mitigate the weight of mandrel to a certain extent.
As shown in Figure 1, 2, in order to mitigate the weight of mandrel, the outer peripheral face of positioning shaft shoulder 3 is equally symmetrically machined with four
The groove of axial direction, the cross section for making positioning shaft shoulder 3 is in equally cross, and sets the section of positioning shaft shoulder 3 in the cone stood upside down
Shape structure, the angle of the taper is 54 °.
Above-described embodiment is the utility model preferably implementation, and in addition, the utility model can be with other sides
