Embodiment Construction

[0009] Product of the present invention will be described in further detail below in conjunction with accompanying drawing and embodiment:

[0010] See attached Figure 1~2 As shown, this kind of aircraft gravity refueling port hole-making frock is characterized in that: the frock includes a lower plate 4 made of a steel plate with a thickness of 30mm, a length of 350mm, and a width of 350mm; , the lower locator 3 made of an aluminum plate with a length of 300mm and a width of 300mm, and a pressure block 2 for pressing the gravity fuel filler and the surface of the lower locator 3 tightly. The shape of the port of the lower locator 3 is according to the gravity fuel filler product. The shape of one end is formed by CNC machining. On one side of the lower plate 4, an upper locator 6 made of an aluminum plate with a thickness of 10mm, a length of 300mm, and a width of 300mm is installed obliquely. The upper locator 6 is supported by the support 5 and connected by connecting bolt...

Abstract

The invention discloses a hole making tool for an airplane gravity oil filling port. The tool comprises a steel lower plate (4); an aluminum lower positioning device (3) and a pressing block (2) used for pressing the gravity oil filling port and the profile of the lower positioning device (3) are fixed to the upper surface of the lower plate (4); the shape of an end port of the lower positioning device (3) is formed in a numerical control machining manner according to the shape of one end of a gravity oil filling port product; on one side of the lower plate (4), a same aluminum upper positioning device (6) is obliquely installed; the upper positioning device (6) is supported by a supporting piece (5) and fixed through a connection bolt (7); the shape of an end port of the upper positioning device (6) is formed in a numerical control machining manner according to the shape of the other end of the gravity oil filling port product; and the supporting piece (5) is also provided with a pressing hook (1) used for pressing the gravity oil filling port and the profile of the upper positioning device (6). The tool has the beneficial effects of being simple in structure and convenient to use, the product quality is effectively improved, and the airplane riveting assembly period is shortened.

Description

technical field [0001] The invention relates to a hole-making tool for an aircraft gravity refueling port, which belongs to the technical field of product structure. The tooling is used for riveting and assembling the drilling of an aircraft gravity refueling port. Background technique [0002] Many welded parts of aircraft products are deformed after welding, and there are assembly inconsistencies after the welded parts are drilled and positioned, such as gaps. Aircraft gravity refueling port - two flanges, two cylindrical parts, and two angles connected to the floor are welded together into two by welding. These cylindrical parts are manufactured separately, although welding tooling is also used for positioning during welding, but the welding deformation tolerance is large. When riveting to assemble the aircraft, the two cylindrical parts of the gravity refueling port are riveted into an assembly. The shape requirements of the two ends of the riveted gravity fuel filler ...
