Abstract
The utility model discloses a threaded hole of an aluminum alloy part, wherein a thread bushing is arranged in the threaded hole; the outer diameter of the thread bushing is identical to the inner diameter of the threaded hole; and the thread bushing is made of a stainless steel material. Through the above structure, the stainless steel thread bushing can replace the threaded hole of the aluminum alloy part to contact with other workpieces; and the stainless steel material is more excellent than the aluminum alloy in wear resistance and strength, so that the service life of the aluminum alloy part is prolonged.
Description
Technical field
The utility model relates to the tapped hole on the tool part, especially the part made of aluminum alloy material.
Background technique
At present, aluminum alloy is widely used in the making machine part, the tapped hole of still making at aluminum alloy part, its wear resistance and intensity are relatively poor, will occur the phenomenon of thread damage after using for several times, affect the connection of each component in the machine, address this problem, seem very urgent.
The model utility content
The technical problems to be solved in the utility model is wear resistance and the intensity that increases the tapped hole of aluminum alloy part.
In order to solve the problems of the technologies described above, technological scheme provided by the utility model is, is embedded in the thread bush that a stainless steel material is made at the tapped hole of aluminum alloy part, and the external diameter of described thread bush is identical with the internal diameter of tapped hole.
Adopt said structure, its beneficial effect is: be provided with thread bush in the described tapped hole, the external diameter of thread bush is identical with the internal diameter size of tapped hole, thread bush just can be embedded in the tapped hole closely, the internal surface of thread bush replaces original tapped hole to contact with other workpiece, thread bush is to be made by stainless steel material, and wear resistance and intensity all obviously are better than aluminum alloy material, has prolonged the working life of part.
Description of drawings
Fig. 1 is the structural representation of the utility model tapped hole.
Among the figure: 1-tapped hole, 2-thread bush.
Embodiment
The utility model is described in more detail below in conjunction with accompanying drawing.
Take the tapped hole 1 of making diameter 8mm as example, the tapped hole 1 that is 8.3mm at diameter of aluminum alloy part upper punch first, getting simultaneously stainless steel parts, to be processed into external diameter be that 8.3mm, internal diameter are the thread bush 2 of 8mm, in thread bush 2 internal surface machining screw, after two workpiece are complete, stainless steel thread bush 2 is embedded in the aluminum alloy tapped hole 1, namely complete.
Claims (2)
1. the tapped hole of an aluminum alloy part, it is characterized in that: be provided with a thread bush (2) in described tapped hole (1), the external diameter of described thread bush (2) is identical with the internal diameter of tapped hole (1).
2. the tapped hole of a kind of aluminum alloy part according to claim 1, it is characterized in that: described thread bush (2) is made by stainless steel material.
