Description

Technical Field

[0001] The present application relates to punching technology, and in particular to an aircraft bulkhead punching device. Background Art

[0002] In aircraft structures, bulkheads are a crucial component of the fuselage. Together with longitudinal beams and stringers, they form the aircraft's skeleton. Their primary functions are to maintain the fuselage's shape, withstand and distribute external loads, and provide support points for the installation of other systems and components. Because bulkheads provide support points for the installation of other systems and components, they require punching at various locations to form mounting holes.

[0003] like Figure 3 An aircraft bulkhead shown in FIG. has mounting holes on its surface distributed on its horizontal ring portion and vertical ring portion. During processing, these mounting holes are generally punched manually after the punching points are marked, which is inefficient and has low accuracy in positioning the punching points. If a conventional automated punching device is used for punching, it is necessary to adjust the angle of the punching device during the punching process to adapt to the different punching points on the horizontal ring portion and the vertical ring portion, or to use two sets of punching devices arranged at different angles, which is more troublesome and has low punching efficiency. Summary of the Invention

[0004] In order to solve the above-mentioned defects of the related prior art, the present application provides an aircraft bulkhead punching device, which can improve the punching efficiency and the accuracy of punching point positioning and has strong practicality.

[0005] In order to achieve the above object, the present invention adopts the following technologies:

[0006] An aircraft bulkhead punching device, comprising:

[0007] The working bin is movable along its own height direction and is rotatable around a fixed rotation axis, the rotation axis is located outside the rear end surface of the working bin and is parallel to the height direction, the rotation axis is equidistant from the two side surfaces of the working bin, and the distance from the working bin is adjustable, the front end surface of the working bin is an outwardly convex arc surface, the center axis thereof is equidistant from the two side surfaces of the working bin, a first matching hole is penetrated through the upper surface of the working bin along the height direction, the first matching hole is equidistant from the two side surfaces of the working bin, a second matching hole is penetrated through the front end surface of the working bin along the length direction of the working bin, the second matching hole is equidistant from the two side surfaces of the working bin;

[0009] The second hydraulic cylinder is arranged outside the front end surface of the working chamber along the length direction. The driving shaft of the second hydraulic cylinder is set toward the working chamber and the size matches the second matching hole. The distance between the second hydraulic cylinder and the two side surfaces of the working chamber is equal. The second hydraulic cylinder is arranged to rotate around the rotating axis following the working chamber, and the distance between the second hydraulic cylinder and the rotating axis is adjustable.

[0010] The beneficial effects of the present invention are:

[0011] 1. The horizontal and vertical ring parts of the bulkhead can be punched using only one working chamber, the first hydraulic cylinder, and the second hydraulic cylinder, which improves the punching efficiency.

[0012] 2. The working chamber can move along its own length and height direction, and can adapt to the punching work of partition frames of different sizes.

[0013] 3. The fourth linear cylinder is used to drive the working chamber, the first hydraulic cylinder, and the second hydraulic cylinder to rotate, which can convert the angle value of the working chamber rotation into the distance value moved along the fourth linear cylinder. When the radius of the bulkhead is large, the positioning accuracy of the punching point can be improved.

[0014] 4. The first rolling column and the second rolling column are used to fix the bulkhead and drive the bulkhead to move, so that the bulkhead can be easily loaded and unloaded, thereby improving the punching efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] When working, the distance between the matching cylinder 218 and the second matching block 417 matches the distance between the matching rod 220 and the first hydraulic cylinder 2, which means that when the matching cylinder 218 is matched with the matching rod 220 and the second matching strip 414 is matched with the second matching groove 413, the driving shaft of the first hydraulic cylinder 2 is coaxial with the first matching hole 11; at this time, the fourth matching block 23 is driven to move by the fourth electric screw 21, and then the fifth slide bar 26 is driven to move.
