Description
Technical field
A kind of elastic collet centering and clamping apparatus is the utility model is related to, belongs to technical field of mechanical processing.
Background technology
In mechanical manufacturing technology, it is common technique that thin-wall sleeve processing is carried out to workpiece, usually by clamping workpiece in car
On three chucks of bed, by bore hole or it is cylindrical be processed, the processing quality of workpiece is difficult to ensure that after this method and productivity
It is relatively low, in order to save production cost, ensure the processing quality of product, improve productivity effect, therefore design a kind of elastic collet and determine
Heart clamping device is very necessary.
Utility model content
To solve the above problems, the purpose of this utility model is precisely in order to solve above-mentioned the deficiencies in the prior art, this practicality
New purpose is to provide a kind of elastic collet centering and clamping apparatus.
To solve the above problems, the utility model is achieved through the following technical solutions：A kind of elastic collet centering folder
Tight device, it is made of taper shank, workpiece, inner clamping type collet, guide finger, opening gasket, clamp nut and taper expansion set；
It is characterized in that：In spindle hole of the taper shank objective reality loaded on one, state；The workpiece is installed on inner clamping type spring
On collet external cylindrical surface；The inner clamping type collet is installed on the axis of cone among taper shank and tapered expansion is put on；The cone
There is a keyway on shape expansion set and be installed on the cylinder of taper shank right end；The guide finger be installed on the cylinder of taper shank right end and
It is equal with the upper groove width of tapered expansion set to sell footpath；The opening gasket and clamp nut are installed on taper shank right end.During processing, by work
On the external cylindrical surface of part insertion elastic collet, and it is close to the left side of workpiece and the end face of mandrel.Nut is tightened, promotes taper
Expansion set is moved to the left, so that the outside diameter increase of elastic collet, workpiece from endoporus and is clamped, turnery processing is carried out, works as processing
Nut is unclamped after completing, elastic collet replys reset condition, you can removes workpiece.
The beneficial effects of the utility model are：A kind of elastic collet centering and clamping apparatus, simple in structure, fast, accurate, precision
The advantages that high, safe and reliable, easy to operate.
Brief description of the drawings
Fig. 1 is a kind of elastic collet centering and clamping apparatus structure diagram.
Embodiment
As shown in Figure 1, a kind of elastic collet centering and clamping apparatus, it be by taper shank 1, workpiece 2, inner clamping type collet 3,
Guide finger 4, opening gasket 5, clamp nut 6 and taper expansion set 7 form；It is characterized in that：1 objective reality of taper shank is loaded on
In the spindle hole that state is one；The workpiece 2 is installed on 3 external cylindrical surface of inner clamping type collet；The inner clamping type spring
Collet 3 is installed in the axis of cone and taper expansion set 7 among taper shank 1；There is a keyway on the taper expansion set 7 and be installed on taper shank
On the cylinder of 1 right end；The guide finger 4 is installed on the cylinder of 1 right end of taper shank and sells footpath and the groove width phase on taper expansion set 7
Deng；The opening gasket 5 and clamp nut 6 is installed on 1 right end of taper shank.During processing, by the cylindrical of workpiece insertion elastic collet
On cylinder, and it is close to the left side of workpiece and the end face of mandrel.Nut is tightened, promotes taper expansion set to be moved to the left, so that
The outside diameter increase of elastic collet, workpiece from endoporus and is clamped, carries out turnery processing, nut, bullet are unclamped after machining
Property collet reply reset condition, you can workpiece is removed.
Above with it is preferable implementation disclose the utility model, so itself and be not used to limitation the utility model, it is all to take
With the technical solution replaced or equivalent transformation is obtained, all fall within the scope of protection of the utility model.
