with the fast development of modern Aviation, space technology, mutually higher requirement should have been arranged to the performance of product, it is complicated that the structure of part also becomes accordingly, and its structure has the characteristics of lightweight, thin-walled property and integration.Because thin-walled parts has lightweight, save material, the characteristics such as compact conformation, thin-walled parts is applied in the modern aerospace field increasingly extensively.
so-called annular thin-wall parts is exactly circular diameter D and the ratio of wall thickness б: D/ б=50～150, its wall thickness is the part between 0.25～2mm generally, this part is typical weak hard parts, and relative rigidity is lower, intensity a little less than, processing technology is poor, particularly to part shape, in the higher situation of dimension precision requirement, they are all very responsive to vibration, cutting force and cutting temperature etc., process yielding and generation vibration, wayward machining accuracy and raising working (machining) efficiency.While particularly approaching final processing dimension, process more difficult.This type of aviation thin-walled parts is realized to the machining of high accuracy, high efficiency and high reliability is the important topic that aviation faces always, and traditional mechanical manufacturing method has been difficult to meet processing request.
Summary of the invention
the purpose of this utility model is: provide a kind of easy to use, simple in structure, and can effectively avoid annular thin-wall parts can produce the frock of the processing thin-walled ring-shaped work pieces of distortion adding man-hour, thereby overcome the deficiencies in the prior art.
the technical solution of the utility model is to form like this: the frock of a kind of processing thin-walled ring-shaped work pieces of the present utility model is, this frock comprises the flexible expansion ring, the flexible expansion ring set is at lower dead ring and tightening on the external cylindrical surface of ring, be provided with the lower convex platform that can be pressed on flexible expansion ring lower end in the lower end of lower dead ring, be provided with the convex platform that can be pressed on flexible expansion ring upper end in the upper end that tightens ring, lower dead ring links together with tightening to encircle by lock bolt and the nut be connected on lock bolt.
above-mentioned the lower dead ring of flexible expansion ring is arranged and tightens between ring at cover be provided with for lower dead ring and tighten the flexible gap of ring while relatively moving.
be symmetrically fixed with two backstays on above-mentioned lower dead ring, and backstay is through tightening ring, on backstay, cover has return spring and adjusting nut is housed, and return spring is arranged on lower dead ring and tightens between ring.
above-mentioned lower dead ring is the taper seat with identical tapering with the external cylindrical surface that tightens ring, and the endoporus of flexible expansion ring is the conical bore identical with this taper seat tapering.
above-mentioned flexible expansion ring is poly-ammoniaester
the flexible expansion ring of elastomeric material.
owing to having adopted technique scheme, the utility model is for distortion and the vibration problem of annular thin-wall parts work in-process, a frock is set in advance in the inner chamber of processed annular thin-wall parts, be provided with the flexible expansion ring on this frock, by this frock, make the flexible expansion ring be close to the internal chamber wall of annular thin-wall parts, can effectively reduce like this vibration that annular thin-wall parts produces in process and effectively prevent that annular thin-wall parts from deforming when its profile of processing.Adopt method of the present utility model and frock can effectively improve the rigidity of annular thin-wall parts work in-process, reduce or eliminate the vibration in processing, effectively avoided the problem on deformation in annular thin-wall parts processing, thereby improved quality and the precision of annular thin-wall parts processing, greatly improved product percent of pass and production efficiency.In addition, the poly-ammonia of the utility model utilizationester
rubber is done the swelling material, poly-ammoniaester
rubber wear-resisting damages, and vibration reduction and cushioning etc. are functional, in working order under, poly-ammoniaester
the rubber swelling ring can fit tightly with the part to be processed surface, and contact-making surface is even, can effectively eliminate vibration and distortion in the thin-wall part process, avoids the injuring part datum level simultaneously, makes part reach the processing effect of expection; Dead ring and tighten ring two taper seats swelling polyurethane rubber tensioner ring when compressing under the utility model utilization, and can guarantee suitable with enough tension forces are arranged.The utility model efficiently solves part machining deformation and a vibration difficult problem, crudy and the part processing precision of annular thin-wall parts all are greatly improved, use proof through reality, part passing rate of processing of the present utility model can reach more than 95%, thereby greatly reduces the single-piece work cost.So compared with prior art, the utility model not only has advantages of easy to use, simple in structure and can effectively avoid the annular thin-wall parts machining deformation the utility model, but also there is the advantages such as high efficiency, crudy are good, long service life.
