Description
Technical field
The utility model relates to a kind of thin-wall sleeve parts fine finishining fixture.
Background technology
Thin-wall sleeve parts is a kind of common part in equipment manufacture, and especially required precision is compared with high large diameter thin wall cover parts because diameter is large, poor rigidity, and processing is very easily out of shape, and more difficultly meets size and Geometrical Tolerance Principle.Therefore thin-wall sleeve parts is the difficult point place in mechanical processing technique always.
Utility model content
The purpose of this utility model is to provide a kind of thin-wall sleeve parts fine finishining fixture, prevents thin-wall sleeve parts from deforming in process when fine finishining.
The technical scheme realizing the utility model object is: a kind of thin-wall sleeve parts fine finishining fixture, comprises machine chuck or ring flange, taper mandrel and lathe are top; The cylindrical axial profile of described taper mandrel is tapered, and its large end is arranged on machine tool chief axis by machine chuck or ring flange; The center of described taper mandrel is provided with axially extending bore; Described lathe is top to be held out against on the axially extending bore of the small end of taper mandrel; The tension force clamping thin-wall sleeve parts produced when described taper mandrel is by putting into thin-wall sleeve parts.
A kind of thin-wall sleeve parts fine finishining fixture, also comprises spacing ring; Described spacing ring is locked on the periphery of taper mandrel, and carries out spacing to the thin-wall sleeve parts on taper mandrel.
Length/40 of the outside diameter=end diameter+× taper mandrel of described taper mandrel.
Have employed technique scheme, the utility model has following beneficial effect: the tension force clamping thin-wall sleeve parts produced when (1) the utility model puts into thin-wall sleeve parts by taper mandrel, and thin-wall sleeve parts is supported in process, solve thin-wall sleeve parts and hold yielding problem, ensure that size and the form and position tolerance of thin-wall sleeve parts.
(2) the utility model is locked on the periphery of taper mandrel by spacing ring, plays the object of location clamping thin-wall sleeve parts, prevents part vibration in process.
Accompanying drawing explanation
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein
Fig. 1 is structural representation of the present utility model.
Label in accompanying drawing is:
Machine chuck or ring flange 1, taper mandrel 2, spacing ring 3, lathe are top 4, thin-wall sleeve parts 5.
Detailed description of the invention
(embodiment 1)
See Fig. 1, the thin-wall sleeve parts fine finishining fixture of the present embodiment, comprise machine chuck or ring flange 1, taper mandrel 2, spacing ring 3 and lathe top 4.
The cylindrical axial profile of taper mandrel 2 is tapered, and its large end is arranged on machine tool chief axis by machine chuck or ring flange 1.The center of taper mandrel 2 is provided with axially extending bore.Lathe top 4 holds out against on the axially extending bore of the small end of taper mandrel 2.The tension force clamping thin-wall sleeve parts 5 produced when taper mandrel 2 is by putting into thin-wall sleeve parts 5.Spacing ring 3 is locked on the periphery of taper mandrel 2, and carries out spacing to the thin-wall sleeve parts 5 on taper mandrel 2.Length/40 of outside diameter=end diameter+0.003 ~ 0.02 × taper mandrel 2 of taper mandrel 2.
The positioning and clamping process of thin-wall sleeve parts 5 is: be first connected with machine tool chief axis by machine chuck or ring flange 1 by taper mandrel 2, then thin-wall sleeve parts 5 is inserted in taper mandrel 2, with gloves tightly, and then spacing ring 3 is adjacent to thin-wall sleeve parts 5 end face and locked, finally hold out against lathe top 4, the positioning and clamping of such thin-wall sleeve parts 5 just completes, only need below to refine thin-wall sleeve parts 5 cylindrical, solve thin-wall sleeve parts 5 well and hold yielding problem, reduce thin-wall sleeve parts and add the deflection in man-hour, ensure the axiality of accessory size and endoporus and external diameter.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
