For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: expansion inner core tube, socket tooth part and detachable positioning block, described socket tooth part is socketed in expansion inner core tube, detachable positioning block is socketed in expansion inner core tube, between socket tooth part, by detachable positioning block interval, and rely on detachable positioning block to complete location is installed.
In preferred embodiment of the utility model, described expansion inner core tube is pipe, is provided with manhole along expansion inner core tube central axial direction.
In preferred embodiment of the utility model, described socket tooth part is provided with manhole along central axial direction, and the manhole slightly larger in diameter of socket tooth part is in expansion inner core tube external diameter.
In preferred embodiment of the utility model, described socket tooth part manhole is provided with tooth, and the tip diameter that tooth top forms is identical with expansion inner core tube external diameter.
In preferred embodiment of the utility model, described tooth is provided with rounding.
In preferred embodiment of the utility model, detachable positioning block is made up of two semicircle annular materials, and semicircle annular material one side is provided with hinge, and opposite side is provided with fastener.
In preferred embodiment of the utility model, described expansion inner core tube is that hydraulic pressure tooth is swollen with the connecting means of socket tooth part.
The beneficial effects of the utility model are: the utility model expanded joint part does not need to manufacture riveted holes and positioning hole, has simplified manufacturing process, reduces costs; By in socket tooth part endoporus place design tooth (polygonal hole needn't tooth processed), improve part strength and also avoid the rotation of part at expanded joint; The tooth of rounding is set, prevents from causing in expanding joint process stress to concentrate and the generation in expanded joint gap.Have connect reliable, adaptability is good, manufacturing efficiency is high, prevents electrochemical corrosion, structural strength is large, has extensive market prospects in automobile market.
Brief description of the drawings
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:
