Description
Technical field
It the utility model is related to a kind of fixture, the particularly adjustable clamp for gear hobbing process.
Background technology
At present, in gear hobbing process, its fixture used is more with pull bar pulling collet progress radial positioning, while according to
Contacted by clamp body with the radial direction step end face on workpiece and carry out axially position, to fix workpiece；But the fixture is only applicable to footpath
To size is larger, workpiece provided with step end face, for radial dimension is smaller, workpiece without radial direction step, due to that can not carry out
Axially position, then it is difficult to be applicable.
The content of the invention
The purpose of this utility model is to be directed to deficiencies of the prior art, there is provided a kind of adjustable gear-hobbing clamp,
It has the advantages of axially position versatility is good, and axial pull distance is adjustable, applied widely so as to adjust clamping force.
To reach above-mentioned purpose, a kind of adjustable gear-hobbing clamp of the present utility model, including clamp body, pull bar and elastic clip
Head, it is characterised in that be sequentially provided with preceding mounting hole, center taper hole and rear mounting hole in clamp body from front to back, preceding mounting hole is with after
Mounting hole is also connected by axial hole, and collet is slided in the preceding mounting hole, and one top is located at by the cone section at its rear portion
In the taper hole of center, top front end is located in the endoporus of collet, and pull bar is slided in rear mounting hole, is provided with axial hole
Axle sleeve, pull bar are connected by the bolt through axle sleeve with collet, and cylindrical be provided with clamp body in collet front end is engaged
The conical surface.
In use, workpiece is inserted in collet, its rear end is contacted with top, elastic clip is pulled back by pull bar
Head, the front end of collet are extruded by clamp body, shunk, and hold workpiece tightly；The utility model is carried out axially by top to workpiece
Positioning, there is the advantages of axially position versatility is good；By changing the axle sleeve of different length, can adjust pull bar axial direction pull away from
From applied widely so as to adjust clamping force；
As further improvement of the utility model, collet front end is provided with more than two axial grooves, in axial groove
Provided with rubber；Both it can realize that collet normally shrank, and prevent impurity from entering in collet again；
As further improvement of the utility model, dust cap is fixedly connected with clamp body front end；It can prevent impurity from entering bullet
Property chuck and fixture mates the conical surface between, ensure normal work；
In summary, the utility model has the advantages of axially position versatility is good, and axial pull distance is adjustable, so as to
Clamping force is adjusted, it is applied widely.
Brief description of the drawings
Fig. 1 is the front view of the utility model embodiment.
Fig. 2 is the left view of collet in Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, a kind of adjustable gear-hobbing clamp, including clamp body 1, pull bar 2 and collet 3, fixture
Preceding mounting hole 4, center taper hole and rear mounting hole 6 are sequentially provided with body 1 from front to back, preceding mounting hole 4 also passes through with rear mounting hole 6
Axial hole is connected, and collet 3 is slided in the preceding mounting hole 4, and the front end of collet 3 is provided with four axial grooves, in axial groove
It is equipped with rubber 10；One top 5 is located in the taper hole of center by the cone section at its rear portion, and top 5 front end is located at collet 3
In endoporus, pull bar 2 is slided in the rear mounting hole 6, is provided with axle sleeve 8 in axial hole, pull bar 2 by the bolt 9 through axle sleeve 8 and
Collet 3 is connected, and the front end of collet 3 is cylindrical to be provided with the conical surface 7 being engaged with clamp body 1；Pass through spiral shell in the front end of clamp body 3
Nail is fixedly connected with dust cap 11.
In use, the one end of workpiece 12 is inserted in collet 3, its rear end is contacted with top 5, by pull bar 2 backward
Collet 3 is pulled, the front end of collet 3 is extruded by clamp body 2, shunk, and holds workpiece 12 tightly；The utility model passes through top
5 pairs of workpiece 12 carry out axially positions, have the advantages of axially position versatility is good, especially suitable for radial dimension it is smaller, without footpath
To the workpiece of step, by changing the axle sleeve 8 of different length, the axial pull distance of pull bar 2 is can adjust, is clamped so as to adjust
Power, it is applied widely；Dust cap 11 can prevent impurity from entering between the conical surface that collet 3 is engaged with clamp body 1, ensure just
Often work.
