Description
Technical field
The present invention relates to field of machining, and in particular to a kind of shaft gear mill internal clamp.
Technical background
Interior hole machined is ground for shaft gear involved in the present invention, is always the difficult point in Gear Processing, due to shaft gear
Inner hole bearing is installed, and two positioning cylindrical surfaces of inner hole to foreign round have concentricity requirement, and concentricity tolerance is again small.For
The processing method of the part is generally clamped using scroll chuck, manual centering Excircle machining.Disadvantage: artificial centering is time-consuming and takes
Power, and concentricity tolerance requirement cannot be completely secured, workpiece surface can be also crushed sometimes；Manually can only visually it judge, it can not
It is precisely controlled, processing efficiency is lower.
Summary of the invention
The present invention is in order to solve the problems, such as mill Internal hole positioning, and the present invention provides a kind of shaft gear mill internal clamp, and feature exists
In: including chuck body, the chuck body upper end is equipped with clamp port, is clamped with ringfeder in the clamp port, in the ringfeder
Wall is the compressive plane with work pieces mate, and outer wall is the positioning surface cooperated with the clamp port inner wall, the chuck body bottom
Equipped with internal positioning structure corresponding with described workpiece one end shape.
Preferably, the clamp port inner wall is the conical surface, one end internal diameter of the clamp port far from the internal positioning structure
It is larger.The open end of the clamp port is opening-like, facilitates and workpiece is pushed into fixture.
Further, several arc grooves are axially uniformly provided with along the ringfeder on the compressive plane.The arc groove has
Wall thickness is thinned, acts on the elastic expansion-sleeve contracting effect that rises preferably.
Preferably, offering notch on the ringfeder, the notch, which has, compensates the effect that rises that contracts.
Further, the workpiece is stepped, the clamp body be equipped with gives up the throne hole, it is described give up the throne hole site with it is described
Workpiece cascaded surface position is corresponding.
Preferably, the internal positioning structure is equipped with location hole corresponding with the workpiece, the internal positioning structure
It is connect with machine tool chief axis hole.The internal positioning structure is fixed in machine tool chief axis hole.
Further, the clamp body is equipped with bolt hole, and screw passes through bolt hole and is screwed with the hole on lathe.
Preferably, the chuck body is equipped with mounting surface, the mounting surface is tapered, the mounting surface and the machine
The cone match of bed main shaft.Interlocking is realized in the mounting surface and cone match installation.
The utility model has the advantages that invention both can guarantee the concentricity of shaft gear inner hole and benchmark outer circle, shaft gear outer circle is ensured that
It is not crushed, improves processing efficiency.

Specific embodiment
As shown in Figure 1, a kind of shaft gear grinds internal clamp, it is characterised in that: including chuck body 1, the chuck body 1
Upper end is equipped with clamp port 14, and 14 inner wall of clamp port is the conical surface, the one end of the clamp port 14 far from the internal positioning structure 4
Internal diameter is larger.It is clamped with ringfeder 2 in the clamp port 14, the ringfeder 2 is spring steel material, and 2 inner wall of ringfeder is and work
The compressive plane 10 that part 3 cooperates, outer wall is the positioning surface 9 cooperated with 14 inner wall of clamp port, when workpiece 3 is pushed into fixture,
Workpiece 3 squeezes 2 inner wall of ringfeder, and 2 outer wall of ringfeder squeezes clamp port 14, to realize that 2 inner wall of ringfeder and workpiece 3 interlock, outside ringfeder 2
Wall and clamp port 14 interlock, and 1 bottom of chuck body is equipped with internal positioning structure 4 corresponding with 3 one end shape of workpiece,
The internal positioning structure 4 is connect with 6 spindle hole of lathe.Several circles are axially uniformly provided with along the ringfeder 2 on the compressive plane 10
Arc slot 11.Notch 12 is offered on the ringfeder 2.The workpiece 3 is stepped, and the clamp body is equipped with gives up the throne hole 7, described
7 position of gives up the throne hole is corresponding with the 3 cascaded surface position of workpiece.The internal positioning structure 4 is equipped with corresponding with the workpiece 3
Location hole 13, one end of the workpiece 3 is inserted into location hole 13, is interference fitted with location hole 13, and the clamp body is equipped with spiral shell
Keyhole 8, the ringfeder 2 are equipped with mounting surface 15, and the mounting surface 15 is tapered, the mounting surface 15 and 6 main shaft of lathe
The conical surface 16 cooperate.The clamp body passes through the bolt hole 8 by screw 5 and is fixed on lathe 6, mounting surface 15 and the conical surface 16
It is coupled, realizes interlocking.
Concrete mode: firstly, entire fixture is fixed on internal grinder by the bolt hole 8 on fixture by bolt
On main shaft end face.Meanwhile internal positioning structure 4 connect and locks with the inner hole of 6 main shaft of lathe.Part is put into ringfeder 2, by zero
The benchmark outer circle of the larger one end of the part diameter of axle is contacted with compressive plane 10 to be positioned, the benchmark outer circle of the smaller one end of the part diameter of axle with it is interior
Location structure 4 cooperates, and realizes the radial limit of part.The cascaded surface of part fits with ringfeder 2, realizes the axial direction of part
Limit.By inwardly pushing part, chuck body 1 and ringfeder 2 are contacted, and realize interlocking, to part positioning outer circle position pressurization, lock
Tightly, the fixation of part is realized.
After process finishing, zero can be easily removed with the cascaded surface for the workpiece 3 that pole sled uncages tight by gives up the throne hole 7
Part removes the part processed.So far, whole process is completed.
