Description

Technical Field

[0001] The present invention relates to a support device, in particular to a support device for omnidirectional hole making during aircraft assembly, belonging to the technical field of design and manufacture of aircraft production and manufacturing process equipment. Background Art

[0002] In the modern aircraft assembly industry, high-precision and stable hole making is very important and is the basis for ensuring the smooth assembly of aircraft. The current hole-making methods include automated hole making, semi-automated hole making, and manual hole making. Among them, semi-automated hole making mainly uses automatic feed drill equipment. However, in actual applications, the linear automatic feed drill can only be placed above the product to be processed, fixed vertically or at a small angle on the drill template, and make holes from top to bottom. It cannot be placed horizontally for hole making, nor can it make holes from bottom to top. Specifically, the linear automatic feed drill can only be installed in the 60°-90° direction above the product to be processed and can only make holes from top to bottom above the product. It cannot be installed at 0° of the product or below the product. Otherwise, due to the self-weight problem of the linear automatic feed drill, stable hole making cannot be achieved, which greatly limits the use scenarios of the linear automatic feed drill.

[0024] Linear automatic feed drill: A type of automatic feed drill, which is integrally cylindrical and long. All its power units, rotating spindle and feed unit are linearly arranged inside the cylindrical shell. The whole device is rotationally connected to the fastening screw protruding from the drill die through the spiral groove at the drilling end.

[0025] such as Figures 1 to 6Shown is a support device for omnidirectional hole making in the aircraft assembly process, which can effectively improve the assembly efficiency of the flying assembly and enhance the utilization rate of the linear automatic feed drill. The support device includes an automatic feed drill 1. The support device further includes an adjustable lifting bracket and a universal support adjustment mechanism. The universal support adjustment mechanism is movably arranged on the adjustable lifting bracket, and the automatic feed drill 1 is arranged on the universal support adjustment mechanism. During the hole making process, the automatic feed drill 1 can drill holes in a specified three-dimensional space in multiple directions through the cooperation of the universal support adjustment mechanism and the adjustable lifting bracket. The technical solution provided in this application is based on the existing automatic feed drill. By adding an adjustable lifting bracket and a universal support adjustment mechanism to form the support device of this application, the universal support adjustment mechanism is movably arranged on the adjustable lifting bracket, and the automatic feed drill is arranged on the universal support adjustment mechanism. Then, during the hole making process, the automatic feed drill can drill holes in a specified three-dimensional space in multiple directions through the cooperation of the universal support adjustment mechanism and the adjustable lifting bracket. This not only solves the technical problem in the prior art that the automatic feed drill can only drill holes in the downward 0° - 30° direction from top to bottom. By arranging the automatic feed drill with the support device provided in this application, since the adjustable lifting bracket can be adjusted up and down in the height direction, and the universal support adjustment mechanism can reciprocally adjust in the X-axis direction and Y-axis direction in the same horizontal plane, and can also be adjusted in the specified three-dimensional space, it can effectively achieve the purpose of improving the assembly efficiency of the flying assembly and enhancing the utilization rate of the linear automatic feed drill. Considering the situation of the prior art, in order to simplify the structure, the adjustable lifting bracket of this application includes a truss support platform and a lifting adjustment support component. The working height of the truss support platform is determined by adjusting the lifting adjustment support component. The universal support adjustment mechanism is reciprocally movably arranged on the top surface of the truss support platform in the X-axis or Y-axis direction in the horizontal plane. Specifically, the truss support platform includes a square frame support truss 2 and a platform plate 3. The platform plate 3 is fixedly installed on the top of the square frame support truss 2. At least three support legs are provided at the lower part of the square frame support truss 2.

The universal support adjustment mechanism is reciprocally movably arranged on the platform plate 3 in the X-axis or Y-axis direction in the horizontal plane.

[0026] Correspondingly, on the basis of being adjustable in the height direction, more-direction adjustment is realized while simplifying the structures of various components as much as possible. The universal support adjustment mechanism of the present application includes a sliding base, a sliding and rotating intermediate transition structure, and a top support adjustment seat. The universal support adjustment mechanism is arranged on the platform plate 3 so as to be reciprocally movable along the X-axis or Y-axis direction through the sliding base.

The drilling end of the automatic feed drill 1 is supported on the top support bottom plate 5 so that the drilling height is adjustable through the tip support adjustment bolt 7 in cooperation with the quick-press buckle 13. The top support bottom plate 5 is fixedly installed on the top of the sliding and rotating intermediate transition structure. The specified drilling direction of the automatic feed drill 1 in the three-dimensional space is determined by adjusting the tip support adjustment bolt 7 in cooperation with the tail fixing bolt. The sliding base preferably includes a base plate 8 and at least one set of self-locking guide rail groups 9. The base plate 8 is arranged on the platform plate 3 so as to be reciprocally movable along the X-axis or Y-axis direction through the self-locking guide rail groups 9. More specifically, the self-locking guide rail groups 9 are two sets. Each set of self-locking guide rail groups 9 respectively includes a T-shaped rail, a set of T-shaped guide chutes, and a self-locking component. The two sets of T-shaped guide chutes are arranged on the platform plate 3 in parallel at a specified distance. The two T-shaped rails are fixedly installed at the bottom of the base plate 8 in a position corresponding to the two sets of T-shaped guide chutes. The base plate 8 is arranged on the platform plate 3 so as to be reciprocally movable along the X-axis or Y-axis direction through the mutually adapted T-shaped rails and T-shaped guide chutes. The T-shaped rails and T-shaped guide chutes in the sliding position are locked by the self-locking component.

[0027] Further, in order to achieve adjustment not only in the vertical direction and the X and Y axis directions in the horizontal plane, but also at any angle within each horizontal plane, the sliding and rotating intermediate transition structure of the present application includes a rotary adjustment component and a linear movement adjustment component. The rotary adjustment component is arranged on the linear movement adjustment component so as to be reciprocally rotatable in the circumferential direction. The linear movement adjustment component is arranged on the base plate 8 so as to be reciprocally movable in the Y-axis or X-axis direction. The top support bottom plate 5 is fixedly installed on the linear movement adjustment component. The linear movement adjustment component includes a sliding support plate 10, two sets of self-locking guide rail groups 9 and two sets of self-locking components. The sliding support plate 10 is arranged on the base plate 8 so as to be reciprocally movable in the Y-axis or X-axis direction through the cooperation of two T-shaped guide rails in two T-shaped guide chutes. The T-shaped guide rails in the sliding position are locked with the T-shaped guide chutes through the self-locking components. The rotary adjustment component is arranged on the sliding support plate 10 so as to be reciprocally rotatable in the circumferential direction. More specifically, the rotary adjustment component includes a rotary support plate 11 and a circular guide rail group 12. The circular guide rail group 12 includes a self-locking component, a circular guide rail and a circular chute. The circular guide rail is arranged at the bottom of the rotary support plate 11, and the circular chute is fixedly installed on the sliding support plate 10.
