Abstract
The invention provides an aluminium alloy casting screw thread embedded reinforcing structure which is used for reinforcing a threaded hole of an aluminium alloy casting so as to prolong the service life of the aluminium alloy casting. The main implementation method is as follows: firstly, a biggish threaded hole is formed on the aluminium alloy casting, and then a steel threaded sleeve is additionally arranged in the biggish threaded hole; the threaded sleeve takes the shape of a round tube, and threads are formed on the outer and the inner sides of the threaded sleeve respectively; the external threads of the threaded sleeve are rightly embedded into the biggish threaded hole on the aluminium alloy casting, and can be fixed with the biggish threaded hole through an adhesive; and the internal threads are used for replacing an original threaded hole of the aluminium alloy casting and playing a fastening role. Therefore, with the effect of the threaded sleeve, the threads of the biggish threaded hole of the aluminium alloy casting are not in direct contact with a fastening screw, and the threads of the soft aluminium alloy casting are protected.
Description
Affiliated technical field:
The present invention relates to the aluminium alloy castings thread and inlay ruggedized construction, be used for the reinforcing of aluminium alloy castings tapped hole, to improve the working life of foundry goods.
Background technique:
Aluminium alloy castings is as diesel engine, the situation of mechanical parts such as petrol engine is very extensive, for ease of the installation of aluminium alloy part and fastening, often to open tapped hole thereon, and the material of aluminum alloy is softer, metallographic intensity is not high, making, in the process of loading and unloading and use, because screw needs repeatedly spinning in and out in tapped hole, or in use because mechanical vibration make iron and steel matter screw crash mutually with aluminum alloy matter tapped hole, thereby make the screw thread of the tapped hole on the softer aluminium alloy castings produce mashed line, the situation of sliding line, influence the working life of part, this situation under the situation of using harder material screw more so.
Summary of the invention:
For overcoming owing to material is softer, metallographic intensity is not high, thereby make the flimsy shortcoming of aluminium alloy castings tapped hole, now propose a kind of aluminium alloy castings thread and inlay reinforcement technique, main implementation method is such: at first, on aluminium alloy castings, open a bigger tapped hole, in this tapped hole, add a steel thread bush then, described thread bush is tubular shape, inside and outside respectively be provided with screw thread, the outside thread of thread bush just in time is inlaid into the aluminium alloy castings tapped hole, available between the two adhesive is fixed, internal thread then is used for substituting former aluminium alloy castings tapped hole, makes fastening usefulness; For improving the life-span, this thread bush can be made of the high duty alloy steel, and like this, because the effect of thread bush, the screw thread of aluminium alloy castings tapped hole does not directly contact with fastening screw, thereby has protected the screw thread of softer aluminium alloy castings.
Advantage of the present invention is: prolonged the life-span of aluminium alloy castings tapped hole greatly, made things convenient for aluminium alloy castings as petrol engine, the parts of machinery such as diesel engine use.
Description of drawings:
Accompanying drawing 1 is a structural principle sectional drawing of the present invention, and accompanying drawing 2 is thread bush elevation of the present invention, wherein: (1) aluminium alloy castings body, (2) thread bush, the outside thread of (3) thread bush, the internal thread of (4) thread bush, (5) screw thread of aluminium alloy castings, (6) fastening screw.
Embodiment:
As shown in Figure 2; open the screw thread (5) of big tapped hole in the aluminium alloy castings body (1) as aluminium alloy castings; in inlay high strength material thread bush (2); thread bush respectively is provided with screw thread inside and outside (2); outside thread (3) as thread bush; the internal thread of thread bush (4); the outside thread of thread bush (3) just in time is inlaid into aluminium alloy castings tapped hole (5); available glue is reinforced between the two; or use the additive method interlock; the internal thread of thread bush (4) is used for substituting former aluminium alloy castings tapped hole; make fastening usefulness; with fastening screw (6) interlock; the fastening screw of iron and steel material quality (6) thereby directly do not contact with aluminium alloy castings tapped hole (5); thereby protected the screw thread of softer aluminium alloy castings; prolonged the life-span of aluminium alloy castings tapped hole greatly, made things convenient for aluminium alloy castings as petrol engine, the parts of machinery such as diesel engine use.
Claims (2)
1. the aluminium alloy castings thread is inlayed ruggedized construction, comprise: the outside thread of aluminium alloy castings body, thread bush, thread bush, the internal thread of thread bush, the screw thread of aluminium alloy castings, fastening screw, it is characterized in that: open the screw thread of aluminium alloy castings on the aluminium alloy castings body, inlay thread bush in the screw thread of aluminium alloy castings.
2. inlay ruggedized construction according to the described aluminium alloy castings thread of claim 1, it is characterized in that: described thread bush is provided with internal and external threads, the outside thread of thread bush and the threaded engagement of aluminium alloy castings, the internal thread of thread bush and fastening screw interlock.
