Abstract
The utility model discloses an expansion shaft sleeve for machining an alloy spindle, and the expansion shaft sleeve comprises a shaft sleeve main body, wherein the shaft sleeve main body is provided with a through hole which is matched with the alloy spindle to be machined, the side wall of the shaft sleeve main body is provided with at least two telescopic gaps which are communicated with the through hole, and one end of each telescopic gap extends to the end surface of the shaft sleeve main body. The expansion shaft sleeve has advantages that due to the existence of the telescopic gaps, the entire shaft sleeve main body has radial elastic force, so that the inner wall of the through hole can be contacted with the alloy spindle in a surface contact way, the alloy spindle is free from shaking when an inner hole is machined, and the concentricity of the inner hole and an outer circle can be well guaranteed when the inner hole is machined.
Description
Technical field
The utility model relates to a kind of alloy mandrel processing expansion axle sleeve.
Background technology
The alloy mandrel is generally cylindrical or conical, have vertically through hole, during existing alloy mandrel processing, it all is first processing excircles, and then processing endoporus, when the processing internal control, just need to use axle sleeve, but present axle sleeve have in the middle of all being one with the suitable endoporus of alloy mandrel periphery, insert in the endoporus alloy mandrel fixing, between the inner hole of shaft sleeve of this structure and the alloy mandrel just some contact or line contacts, the alloy mandrel can produce shake when the machine tooling endoporus, has influence on the axiality between alloy mandrel endoporus and the cylindrical.
The utility model content
The purpose of this utility model is to provide a kind of alloy mandrel processing to use the expansion axle sleeve, can effectively solve existing alloy mandrel and use when axle sleeve is fixing processes endoporus the problem that the axiality between endoporus and the cylindrical is difficult to guarantee.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of alloy mandrel processing expansion axle sleeve, comprise the axle sleeve body, have the through hole suitable with processed alloy mandrel on the described axle sleeve body, have at least two expansion joints that communicate with through hole on the sidewall of described axle sleeve body, an end at described expansion joint extends to the end face of axle sleeve body.
Preferably, extend to two opposite end faces of axle sleeve body at described two adjacent expansion joints; Guarantee that this physical efficiency of axle sleeve area and alloy core as much as possible is coupling tactile.
Preferably, the axis of described through hole overlaps with the axle sleeve body axis, and described expansion joint is parallel with the axis of through hole; Be convenient to processing, also be beneficial to this device and better use.
Compared with prior art, the utility model has the advantages that: because the existence at expansion joint, make whole axle sleeve body have certain radical elasticity, can make through-hole wall and alloy mandrel carry out face contacts, the alloy mandrel can not produce and rock when the processing endoporus, thereby can guarantee with cylindrical good axiality is arranged when the processing endoporus.
Description of drawings
What Fig. 1 was the processing of a kind of alloy mandrel of the utility model with the expansion axle sleeve partly cuts open schematic diagram.
The specific embodiment
Consulting Fig. 1 is the embodiment that the expansion axle sleeve is used in a kind of alloy mandrel processing of the utility model, a kind of alloy mandrel processing expansion axle sleeve, comprise axle sleeve body 1, have the through hole 2 suitable with processed alloy mandrel on the described axle sleeve body 1, have at least two expansion joints 3 that communicate with through hole 2 on the sidewall of described axle sleeve body 1, one end at described expansion joint 3 extends to the end face of axle sleeve body 1, extend to 1 two opposite end faces of axle sleeve body at described two adjacent expansion joints 3, article one, the left side of axle sleeve body 1 is reached at expansion joint 3 left always, the right side of axle sleeve body 1 is just reached at second expansion joint 3 to the right always, the axis of described through hole 2 and 1 dead in line of axle sleeve body, described expansion joint 3 is parallel with the axis of through hole 2.
The alloy mandrel is inserted through hole 2 from axle sleeve body 1 one ends, because the existence at expansion joint 3, make whole axle sleeve body 1 have certain radical elasticity, can make through hole 2 inwalls and alloy mandrel carry out face and contact, thereby when the processing endoporus, can guarantee with cylindrical good axiality is arranged.
The above only is specific embodiment of the utility model, but technical characterictic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification all are encompassed among the claim of the present utility model.
