Description
Technical field
The utility model belongs to machining technology field, is related to a kind of machining frock, more particularly to a kind of for thin
Wall covers the centrifugation main axis of dilatation of profile and end face processing.
Background technology
The main machined surface of thin-wall sleeve parts is endoporus, cylindrical and end face, the installation way of usual thin-wall sleeve parts
There are two kinds：First, in a manner of radial clamping, such as hole positioning, make clamping and positioning using resilient sleeve or the axle that rises；Second, with axial grip
Positioning method, such as it is clamped positioning from axial direction with pressing plate.It is above-mentioned normal because the wall of thin-wall sleeve parts is thin and low intensity
Clamping and positioning method all can cause thin-wall sleeve parts to be processed to be easy to be deformed, and then influence machining accuracy.
Utility model content
The purpose of this utility model is to provide a kind of centrifugation main axis of dilatation, and it is caused swollen using centrifugal force caused by axle rotation
Swelling shaft expands stretching cover parts, reaches positioning and clamps the purpose of cover parts, and will not be deformed, effective to solve
The problem of prior art is present.
The technical scheme that the utility model uses to achieve the above object is：One kind centrifugation main axis of dilatation, including main axis of dilatation master
Body and the connecting shaft for being connected with lathe chuck, connecting shaft are connected with the end of main axis of dilatation main body；The main axis of dilatation main body is
Hollow cylinder, at least 2 narrow slits is cut with the circumferential side wall of main axis of dilatation main body, before the narrow slit is by main axis of dilatation main body
End face is extended back, and narrow slit annular array centered on the axis of main axis of dilatation main body is set.
It is of the present utility model further technical scheme be：The axle center of the main axis of dilatation main body and the axle center of connecting shaft are same
On straight line；The external diameter of the main axis of dilatation main body is smaller 0.5 ~ 1mm than the internal diameter of workpiece to be processed.
It is of the present utility model further technical scheme be：The connecting shaft is connected by the end of connecting plate and main axis of dilatation main body
Connect；The connecting plate is circle, and its external diameter is more than the external diameter of main axis of dilatation main body.
Centrifugation main axis of dilatation of the present utility model is cut with narrow slit, thin-wall sleeve parts on the circumferential side wall of main axis of dilatation main body
Be enclosed on the outside of main axis of dilatation main body, when lathe chuck drives the rotation of main axis of dilatation main body, under the action of the centrifugal force, main axis of dilatation main body with it is thin
The radial dimension of wall cover parts contact jaw can become big, so as to expand simultaneously stretching part, reach the purpose of positioning and Clamp blocks；
The utility model is automatically performed the positioning and clamping of part, and thin-wall sleeve by centrifugal force caused by centrifuging main axis of dilatation rotation
The inner surface entirety uniform stressed of class part, it can be ensured that thin-wall sleeve parts will not be deformed during clamping, while can also be protected
Hold enough clamping forces, enhance clamping rigidity, have the advantages that it is simple in construction, be easy to clamping, dismantle it is quick, greatly improve
Operating efficiency.
The utility model centrifugation main axis of dilatation is further described with reference to the accompanying drawings and examples.

Embodiment
As shown in Figure 1 and Figure 2, a kind of centrifugation main axis of dilatation of the utility model, including main axis of dilatation main body 3 and for lathe card
The connecting shaft 1 of disk connection, the connecting shaft 1 is connected by connecting plate 2 with the end of main axis of dilatation main body 3, and main axis of dilatation main body 3
Axle center and connecting shaft 1 axle center on the same line, ensure the machining accuracy of part.
Main axis of dilatation main body 3 of the present utility model is hollow cylinder, and its external diameter is smaller than the internal diameter of workpiece to be processed
0.5~1mm；In addition, being cut with least 2 narrow slits 31 on the circumferential side wall of main axis of dilatation main body 3, the narrow slit 31 is by main axis of dilatation master
The front end face of body 3 is extended back, and the annular array centered on the axis of main axis of dilatation main body 3 of narrow slit 31 is set.
In the present embodiment, 4 narrow slits 31 are cut with the circumferential side wall of main axis of dilatation main body 3, i.e., with main axis of dilatation main body 3
Centered on axle center, narrow slit 31 is arranged in " ten " font.
When being processed to workpiece, connecting shaft 1 is connected with lathe chuck, and thin-wall sleeve parts 4 are enclosed on main axis of dilatation main body 3
Outside, when lathe chuck drives the rotation of main axis of dilatation main body 3, under the action of the centrifugal force, main axis of dilatation main body 3 and thin-wall sleeve parts 4
The radial dimension of contact jaw can become big, so as to expand simultaneously stretching part, reach the purpose of positioning and Clamp blocks.
In addition, connecting plate 2 of the present utility model is circle, and its external diameter is more than the external diameter of main axis of dilatation main body 3, that is, connects
Plate 2 forms a step in the end of main axis of dilatation main body 3, and when thin-wall sleeve parts are enclosed on main axis of dilatation 3 outside of main body, the step rises
To spacing effect.
Above example is only preferred embodiment of the present utility model, and structure of the present utility model is not limited to above-mentioned implementation
The form that example is enumerated, such as：The quantity of narrow slit 31 is not limited to 4 cited by the present embodiment, can be according to needs of production
Cut 3 or 5 or other suitable quantity, any modification of all made within spirit of the present utility model and principle, etc.
