Abstract
The utility model relates to a replaceable mandrel fixture, which can not only enable the elastic end of a fixture body to clamp a workpiece under the condition of minimum deformation, but also can make the assembly and disassembly of the workpiece convenient and fast. The technical scheme for realizing the aim of the utility model is that: the replaceable mandrel fixture is formed by a mandrel and a locating surface arranged on the mandrel, one end of the mandrel is in a conical shape with the size and the taper being consistent to that of a spindle hole which is connected with a machine tool, the other end of the mandrel is provided with a threaded hole and is sleeved with a shaft sleeve, and the bottom end face of the shaft sleeve is fixed on the other end of the mandrel through a bolt.
Description
Technical field
The utility model relates to field of machining, particularly the anchor clamps of processing thin-walled part.
Background technology
When the thin-walled parts that the axiality of processing excircles and endoporus is had relatively high expectations, general technology is: the folder cylindrical, face work and endoporus are then with anti-three-jaw support endoporus, processing excircles and groove.But in the practical operation because the axiality of anti-three-jaw and machine tool chief axis axis can not strict guarantee, and because workpiece wall is thin, support endoporus after, yielding, cause the axiality of the cylindrical of workpiece and endoporus overproof.Therefore, need a kind of axle anchor clamps, the centering precision height, simple in structure, cost is low.
Summary of the invention
The purpose of this utility model is to provide a kind of replaceable axle anchor clamps, and these anchor clamps both can make elastic tip clamping work pieces under the as far as possible little situation of distortion of clamp body, can make workpiece loading and unloading convenient, fast again.
Realize that the utility model purpose technical scheme is: a kind of replaceable axle anchor clamps, form by axle and the locating surface that is arranged on the axle, it is conical that one end of axle is, its size, tapering are consistent with the spindle hole of institute's connection lathe, the described axle other end is provided with a screwed hole, and being with axle sleeve, the bottom face of axle sleeve is fixed on the axle other end by screw.
During use, workpiece is contained on the axle other end, the end face of workpiece and the locating surface on the axle are adjacent to, unlikely crooked, reinstall axle sleeve, the workpiece swelling on axle, is fixed on axle sleeve on the axle with screw again.After completion of processing, unclamp screw, take out axle, can take off workpiece like a cork.
The utility model can be selected axle sleeve as required, makes the cylindrical of anchor clamps adapt to processing request.The external diameter of workpiece endoporus and axle adopts matched in clearance, so both can make elastic tip clamping work pieces under the as far as possible little situation of distortion of clamp body, can make workpiece loading and unloading convenient, fast again.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1.
The specific embodiment
Be described further below in conjunction with drawings and Examples.
Embodiment 1
A kind of replaceable axle anchor clamps, form by axle 1 and the locating surface 2 that is arranged on the axle 1, it is conical that one end 3 of axle is, its size, tapering are consistent with the spindle hole of institute's connection lathe, the axle other end 4 is provided with the screwed hole 8 of a hold-down screw, the axle other end is with axle sleeve 5, and the bottom face of axle sleeve is fixed on the axle other end 4 by screw 6.
During use, earlier pinching screw is unclamped, workpiece 7 is contained on the axle other end 4, the end face of workpiece and the locating surface on the axle 2 are adjacent to, unlikely crooked, reinstall axle sleeve, screw screw 6.After completion of processing, unclamp screw 6, take out axle 1, can take off workpiece like a cork.
Claims (1)
