Abstract
The electromagnetically heating riveting device for airplane includes a pneumatic riveting hammer, and features its tubular skeleton around the head of the pneumatic riveting hammer, the heating winding around the front end of the tubular skeleton, the C-shaped magnet strips homogeneously around the heating winding and the rivet fixing clamp installed inside the tubular skeleton. The present invention adopts non-contact electromagnetically inducing heating winding to heat the rivet, and this results in no need of surface treatment of the rivet before heating, high heat efficiency, high heat stability and fast heating speed. Mounting the electromagnetically heating riveting device in the head of the pneumatic riveting hammer makes it possible for in-situ direct pneumatic hamming and riveting on the heated rivet in high work efficiency and lowered labor strength.
Description
Technical field
The invention belongs to a kind of control device of machine riveting, is a kind of airplane riveting electromagnetism heating and pneumatic riveting integrated apparatus, is a kind of Electromagnetically heating airplane riveting device specifically.
Background technology
Riveted joint is one of important coupling method of aircaft configuration, and riveting quality greatly affects the life-span of aircraft.The safe operating life of present generation aircraft requires growing, and traditional manual rivet is difficult to guarantee life requirements, therefore must adopt advanced brill riveting assembly equipment to realize stable high-quality.Along with increasing of the new machine of China, the employing of large-diameter rivets securing members such as titanium alloy, high temperature alloy, stainless steel is also more and more many, these rivet bar cold plasticities are poor, to strain rate sensitivity, yield tensile ratio height, cold deformation difficulty, make that common cold riveting technology existence riveted joint difficulty is big, efficient is low, need at high temperature carry out hot riveting.
And present China does not also have the hot riveting equipment at the aircraft special use, that adopts is still heating and rivets the clinching method that separates, it is hot to after the rivet heating promptly to have a resistance with electric iron or the direct energising of rivet, with clamping device rivet is put in the rivet hole, again with hydraulic pressure or the riveting of pneumatic riveting gun pressure hammer, there are uneven, the shortcomings such as efficient is low, the easy scorification of electrode contact point, inconvenient operation of heating in these methods, can't guarantee the efficient and the riveting quality of aircraft riveted joint, this has influenced China's aircraft maintenance capability.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing hot riveting technology, and provide a kind ofly adopt electromagnetic inductive heating principle, heat power efficiency height, electromagnetism heating and the incorporate Electromagnetically heating airplane riveting device of pneumatic riveting that labour intensity is low.
In order to realize purpose of the present invention, the technical solution adopted in the present invention is: comprise pneumatic riveting gun, be characterized in: have a tubular skeleton to be sleeved on the head of pneumatic riveting gun, heater coil twines tubular skeleton front end, heater coil has uniform C type magnetic stripe outward, and the rivet geometrical clamp is installed in tubular skeleton;
The rear end of above-mentioned rivet geometrical clamp connects spring, and heater coil links to each other with stube cable and makes things convenient for the impulse magnetization electric current of outside input alternation;
Above-mentioned tubular skeleton adopts high-temperature resistance plastice, and pneumatic riveting gun can slide in tubular skeleton;
Above-mentioned rivet geometrical clamp adopts high temperature ceramic material, and the front end longitudinal section of rivet geometrical clamp is trapezoidal, and rivet geometrical clamp front end lower surface is fluted, and the middle part is fixed on the tubular skeleton, and the rear end produces chucking power under the effect of spring force;
Above-mentioned rivet geometrical clamp can be backed down by rivet and pneumatic riveting gun;
6 altogether of above-mentioned C type magnetic stripes are distributed on around the heater coil;
The distance of above-mentioned heater coil 1 rear end from the rear end of tubular skeleton 2 is 30-80mm.
Because the present invention adopted the noncontact electromagnetic induction heating coil to heat rivet, make that this hot riveting device need not any processing is done on the rivet surface when rivet heats, and heat power efficiency height, Heat stability is good, firing rate are fast.Because electromagnetic heater is assemblied in the pneumatic riveting gun head, but make rivet heating back, improved operating efficiency, reduced labour intensity directly with regard to the riveting of original position beche.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
The present invention is described further below in conjunction with drawings and Examples.
The present invention includes: tubular skeleton 2, heater coil 1, rivet geometrical clamp 6, spring 8, C type magnetic stripe 7, pneumatic riveting gun 4, moulding heading 3 and stube cable 9.Tubular skeleton 2 is sleeved on the head of pneumatic riveting gun 4 as the skeleton of heater coil 1, rivet geometrical clamp 6 etc., and it slides before and after can be on pneumatic riveting gun 4.Tubular skeleton 2 front ends twine heater coil 1, heater coil 1 outer uniform C type magnetic stripe 7, and C type magnetic stripe 7 is used for shielding and absorbs magnetic field, prevents that pneumatic riveting gun 4 is heated.Adopt the rivet geometrical clamp 6 of lever principle to be used for fixing heated rivet 5, the fulcrum of rivet geometrical clamp 6 is fixed in tubular skeleton 2 walls, and front end is used for fixing rivet 6, and the rear end produces the chucking power of rivet 5 under the effect of spring 8.Outside pulse alternating current is input to heater coil 1 through stube cable 9 and produces pulsed magnetic field, and pulsed magnetic field makes and is heated rivet 5 generation eddy current, thereby is heated (see figure 1) rapidly.
In an embodiment of the present invention, rivet 5 backs down rivet geometrical clamp 6 from the front end insertion of tubular skeleton 2, pneumatic riveting gun 4 is moved on in tubular skeleton 2 backmost, and heater coil 1 begins to rivet 5 heating, behind the heating certain hour then, stop rivet 5 heating, with pneumatic riveting gun rivet 5 is aimed to join then and bore good rivet hole, shift pneumatic riveting gun 5 onto front end from tubular skeleton 2 rear ends, back down rivet geometrical clamp 6, and rivet 5 headed in the rivet hole, hammer riveting into shape with pneumatic riveting gun 4 again.
Should illustrate that at last embodiments of the invention only are used to technical scheme is described and are unrestricted.More than the present invention is had been described in detail, those of ordinary skill also is appreciated that and it still can make amendment or be equal to replacement disclosed technical scheme.And all do not break away from the modification and the replacement of the spirit and scope of technical solution of the present invention, and it all should be encompassed in the middle of the claim scope of the present invention.
The content that is not described in detail in this specification belongs to this area professional and technical personnel's known prior art.
