Description
Technical field
The art belongs to field of machining, particularly relates to a kind of elongated flexible element tensioner support.
Background technology
In machinery industry, composite material forming and some production, excessive to draw ratio or that intensity is not enough elongated flexible element is often needed to process.The rigidity of elongated flexible element is poor, during clamping under gravity, will produce amount of deflection, add the impact of the operating force such as cutting force, winding power, elongated flexible element adds man-hour, can produce and tremble, beat, get rid of curved phenomenon, cause processing difficulties, and finished size, shape all have larger change, composite material solidification distortion is serious, common is drum type and bending etc., causes product rejection.
Current machining common method has centre frame, changes the method such as cutting data and cutting-tool angle.Though size, form accuracy can be improved, amount of deflection during clamping can not be eliminated, also have and tremble, beat, get rid of the generations such as curved, impact processing and precision.For composite material forming, because it does not have centre frame, pulling force is determined by properties of product, bad placement during solidification, so do not improve the measure of processing difficulties, deformation of products.Only have and ensured the quality of products by inspection rejecting, percent defective is high, and production efficiency is low.

Be provided with support set between two described bearings one, described being arranged between inboard bearing one and conjugation handle is provided with back-up ring.
Back-up ring is provided with between described bearing two and guide sleeve.
Gain effect of the present utility model is:
The utility model is supported elongated flexible element by the conjugation handle sleeve and guide sleeve being arranged on support two ends, guide is by screw thread and adjusting sleeve, locking cap connects, can by elongated flexible element tensioner, the duplex bearing arranged in conjugation handle sleeve and the interior bearing arranged of guide sleeve form asymmetric structure, ensure concentricity, rigidity and the processing of adaptation cantilever position, the utility model can be used for turning, grinding, polishing, composite material forming, the machining such as be heating and curing, there is applicability, versatility and economy, structure of the present utility model is simple, reasonable in design, easily manufactured, low cost of manufacture, obviously can improve elongated flexible element machine and add size and dimension precision, solve the difficult problem such as winding difficulty, curing deformation run in composite material forming, significantly reduce percent defective, improve production efficiency and quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of elongated flexible element tensioner of the utility model support.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
See sequence number in Fig. 1, figure: 1 be bow-shaped support, 2 be conjugation handle sleeve, 3 be guide sleeve, 4 be conjugation handle, 5 for bearing one, 6 be back-up ring, 7 be support set, 8 be screwed hole, 9 be screw, 10 be guide, 11 for bearing two, 12 be adjusting sleeve, 13 be locking nut, 14 be thread segment, 15 for elongated flexible element and 16 be counterbore.
Embodiment one: as described in Figure 1, a kind of elongated flexible element tensioner of the utility model support, comprise bow-shaped support 1, be arranged on conjugation handle sleeve 2 and the guide sleeve 3 at bow-shaped support 1 two ends, described conjugation handle sleeve 2 is provided with conjugation handle 4 by two bearing 1 fixed covers, be provided with pin 10 by bearing 2 11 slip cap in described guide sleeve 3 to overlap, the end of described conjugation handle 4 and guide 10 correspondence is equipped with the counterbore 16 matched with elongated flexible element, described counterbore 16 sidewall all offers screwed hole 8, and coupling is provided with lock-screw 9 in described screwed hole 8, described guide 10 outer end is provided with thread segment 14, described guide sleeve 3 outer end is provided with the adjusting sleeve 12 of mating with thread segment 14, the thread segment 14 of described guide 10 outer end is also provided with locking nut 13.The tubing welding of described bow-shaped support 1, be provided with support set 7 between two described bearings 1, described being arranged between inboard bearing 1 and conjugation handle 4 is provided with back-up ring 6, is provided with back-up ring 6 between described bearing 2 11 and guide sleeve 3.
Anti-for elongated flexible element 15 two ends coupling putting is equipped with in counterbore 16 in the end of conjugation handle 4 and guide 10 correspondence, tighten lock-screw 9, elongated flexible element 15 is supported by bow-shaped support 1, then bow-shaped support 1 is rotated, guide 10 is made to screw in adjusting sleeve 12 and locking nut 13, by elongated flexible element 15 tensioner.
The utility model is after tensioner elongated flexible element 15, and one end is connected with machine tool chief axis chuck, and the other end can have three kinds of operating modes: one is that elongated flexible element 15 stressing conditions is best with the chuck clamping other end of living; One holds out against the other end with live center, counteracts part expanding force, stressed poor; Last one is that the other end is in vacant state, and this situation is only applicable to shorter smallclothes.
