The little stress of weak rigidity aerospace component fills shock-absorbing mounting and clamping system
Technical field
The utility model relates to the process equipment field of aerospace component, and particularly the little stress of a kind of weak rigidity aerospace component fills shock-absorbing mounting and clamping system.
Background technology
In aerospace component, some is frame-type part, its poor rigidity, and machining can cause judder, even cannot process;
In prior art, to the solution technique of this problem be: adopt a large amount of fixture, for the part of different-stiffness, adopt different clamping scheme, simultaneously, cutting parameter is also supporting separately, and a complete scheme will be made, need to manufacture a large amount of fixtures, the position simultaneously clamped, contact area etc., need through long-term experience accumulation, or the finite element analysis of complexity, and after clamping, for the processing of structural member, because the rigidity at each position is different, so processing scheme is also need the experience accumulation through long-term, or the finite element analysis of complexity, all very conservative under normal circumstances, because the aerospace component rigidity of this frame-type is inadequate, vibrative words in processing, meeting error is very large,
As previously discussed, these techniques all can the serious processing cost that must increase aerospace component, and efficiency is very low simultaneously, and the learning cost of workman is also relatively high.
Utility model content
For prior art Problems existing, goal of the invention of the present utility model is to provide a kind of and cuts down finished cost, improve working (machining) efficiency, reduce the little stress of weak rigidity aerospace component of workman's learning cost fills shock-absorbing mounting and clamping system.
To achieve these goals, the technical solution adopted in the utility model is:
The little stress of a kind of weak rigidity aerospace component fills shock-absorbing mounting and clamping system, and it comprises:
Fixture, it is close with aerospace component two ends match profiles, is arranged on the fixture at aerospace component length direction two ends, and fixture outside is installed on the table;
Supporter, its two ends are fixedly connected between the fixture at described aerospace component two ends, and supporter runs through aerospace component inside;
Filler, it is the fluid that can solidify, and fills aerospace component inner space.
The system of the application in use, other fixtures various of the removing main clamp in prior art around aerospace component are directly cast out, two fixtures coordinated with aerospace component are installed at aerospace component two ends, described supporter is set between fixture, form the structure of main holding capacity, and the fluid after described solidification, fill full aerospace component inner space, at this moment the power on aerospace component framework is by the fluid after solidification, pass on described supporter, fluid after solidification instead of the fixture cast out, originally clamping from aerospace component outside, promote the mode of aerospace component rigidity, become from aerospace component inner support,
Remove a large amount of unnecessary fixtures, after having clamped, add man-hour, as long as the fluid rigidity after solidification reaches requirement simultaneously, no longer need the problem considering whether to vibrate, greatly reduce requirement during machining, also do not need complicated clamping, machining scheme, reduce great amount of cost, and use the processing technology after the application's system more simply too much than in the past, improve working (machining) efficiency, scheme is convenient easy to learn simultaneously, reduces workman's learning cost.
As preferred version of the present utility model, also comprise secondary supporting construction, its two ends coordinate with aerospace component two ends, and are fixed on described supporter, and described fixture gives its clamping at the outside two ends of aerospace component, described secondary supporting construction is at inner support aerospace component, secondary supporting construction is fixedly mounted on supporter simultaneously, and supporter is fixedly connected with fixture again, forms integrative-structure, after the fluid solidification of filling, make aerospace component rigidity larger more stable.
As preferred version of the present utility model, described supporter is strip extrusion, and structure is coherent symmetrical, and rigidity is large, more stable.
As preferred version of the present utility model, described secondary supporting construction interlude is extrusion, and two ends are airtight, and structure is coherent symmetrical, and rigidity is large, more stable.
As preferred version of the present utility model, described supporter is cylinder, and the junction of its two ends and described fixture is positioned in the geometric center of fixture and aerospace component contact surface, be fixture, supporter form load-carrying construction rigidity larger.
As preferred version of the present utility model, the contact surface of described secondary supporting construction two ends and aerospace component is regular hexagon, and symmetrical configuration, stability is strong.
As preferred version of the present utility model, described secondary supporting construction is hollow structure, and its interlude is regular hexagon extrusion.
The beneficial effects of the utility model are:
Cut down finished cost, improve working (machining) efficiency, reduce workman's learning cost.
