Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
Expansion sleeve fixture suitable for numerically controlled lathe as shown in Figure 1, Figure 2, includes ringfeder main body 1, and unusual is in
In: in order to which subsequent connection component can be cooperated to realize adjustable automation swelling, several expansion knots are distributed in ringfeder main body 1
Structure.Also, for the storage for realizing pre-determined bit to parts to be processed 3, the utility model is provided with positioning above ringfeder main body 1
End face.Meanwhile in order to cooperate ringfeder main body 1, realizes upper and lower clamping position, be connected with cover plate assembly in ringfeder main body 1.And
And the company suitably positioned can be possessed between ringfeder main body 1 after parts to be processed 3 for the ease of ringfeder main body 1
Effect is connect, is not in slide or loosen, is provided with positioning component in ringfeder main body 1.
From the point of view of the preferable embodiment of the utility model one, in order to be realized during clamping parts to be processed 3
Effective expansion, and guarantee that the uniform stressed of 1 upper end of ringfeder main body meets more firm clamping, the expansion structure used is expansion
