Description

Technical Field

[0001] This utility model relates to the field of aircraft manufacturing technology, specifically to a lifting and raising auxiliary device for processing the entire aircraft shell. Background Technology

[0002] An airplane specifically refers to a means of transportation that can fly at high altitudes. The surface of an airplane may be equipped with an engine and wings, or with a propeller, etc. In order to prevent the airplane from being damaged by atmospheric pressure at high altitudes and breaking or being damaged, its internal and external components need to be integrally molded or firmly welded together during manufacturing. During the processing, the height of the fuselage parts needs to be adjusted by lifting devices.

[0003] Current auxiliary devices often rely solely on a single lifting mechanism to adjust the height of the casing or similar objects. This overlooks the fact that if the casing is too large and heavy, it is difficult to maintain its left-right balance during lifting, making it prone to falling and causing collisions.

[0004] Now, a novel lifting and raising auxiliary device for machining the entire machine casing is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a lifting and raising auxiliary device for machining the entire machine casing, so as to solve the problem of lack of support structure mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lifting and raising auxiliary device for machining an entire machine shell, comprising a base and an aircraft shell, wherein the aircraft shell is disposed between the two sides of the top of the base, a base is welded to the center of the top of the base, and a drive motor is fixed to the front end of the base, a support plate is hinged between the front and rear of the interior of the base, a tube is fixed to the four corners of the top of the base, and a guide rod is welded to the lower part of the interior of the tube, a cylinder is sleeved on the upper part of the outside of the guide rod, a hinge rod is fixed to the top of the piston rod of the cylinder, and a spring is welded between the bottom of the cylinder and the tube, and an adjustment plate is movably connected between the front and rear of the top of the hinge rod.

A threaded groove is provided horizontally inside the sleeve. A bevel gear one is welded at the center of the screw. A bevel gear two is movably connected at the center of the bottom end of the transverse groove. A servo motor is installed at the center of the lower part of the outside of the base. A square slot is provided on each side of the transverse groove.

[0010] Preferably, the servo motor can guide the second bevel gear to rotate, and the second bevel gear can mesh with and drive the first bevel gear to rotate.

[0011] Preferably, the outer wall of the screw matches the threaded groove, and the outer wall of the sleeve with its angular edges can move horizontally along the square groove.

[0012] Preferably, a back plate is welded to the rear of the top of the base, and slots are provided on both sides of the inner top of the back plate. A column is movably inserted into the slot, and screw holes are provided between the top and bottom of the column surface. Bolts are installed in the holes on both sides of the front top of the back plate. A frame is welded between the tops of the columns, and a movable chamber is provided between the two sides of the inner top of the frame.

[0026] Specifically, if Figure 1 and Figure 2 As shown, the aircraft shell 10 is horizontally attached to the support plate 13. The drive motor 15 at the front end of the start base 14 can swing the aircraft shell 10 left and right on the support plate 13. The hinge rods 21 and the adjustment plate 32 supported by the cylinders 31 on both sides are also attached to the lower surface of the aircraft shell 10. The surface of the adjustment plate 32 has a frosted plate, which not only prevents the aircraft shell 10 from sliding, but also allows the aircraft shell 10 to be raised and lowered vertically under the restriction of the bottom guide rod 24 and the spring 23.

[0027] A transverse groove 2 is provided between the two sides inside the base 1, and a screw 3 is horizontally mounted at the center of the transverse groove 2. Sleeves 8 are respectively sleeved on both sides of the outside of the screw 3, and a push plate 9 is longitudinally fixed on the side of the sleeve 8. A threaded groove 7 is provided horizontally inside the sleeve 8. A bevel gear 4 is welded at the center of the screw 3. A bevel gear 5 is movably connected at the center of the bottom end inside the transverse groove 2. A servo motor 6 is installed at the center of the lower part of the outside of the base 1. A square slot 30 is provided on each side of the transverse groove 2.

[0028] Servo motor 6 can guide bevel gear 2 5 to rotate, bevel gear 2 5 can mesh and drive bevel gear 1 4 to rotate, the outer wall of screw 3 matches the threaded groove 7, and the outer wall of sleeve 8 with sharp edges can move horizontally along the square slot 30.

[0029] Specifically, if Figure 1 and Figure 3As shown, to reinforce the aircraft shell 10 installed on the base 1, the servo motor 6 at the bottom is started, so that the rotating bevel gear 2 5 meshes with the bevel gear 1 4, forcing the screw 3 installed in the base 1 to rotate horizontally. Since the square slots 30 on both sides match the outer edges of the sleeve 8, the sleeve 8 and the push plate 9 can be horizontally retracted or pushed out to clamp and fix the aircraft shell 10 from both sides.

[0030] A back plate 11 is welded to the rear of the top of the base 1, and slots 18 are provided on both sides of the top of the back plate 11. A column 16 is movably inserted into the slot 18, and screw holes 17 are provided between the top and bottom of the surface of the column 16.

Under the lubrication of the ball bearings 25, the roller 27 moves left and right along the inner wall of the movable chamber 29 to change the position of the processing equipment.

[0032] Working principle: In use, the aircraft shell 10 is horizontally attached to the support plate 13. The drive motor 15 at the front end of the base 14 is activated, allowing the aircraft shell 10 to swing left and right on the support plate 13. The hinge rods 21 and adjusting plates 32, supported by cylinders 31 on both sides, are also attached to the lower surface of the aircraft shell 10. The surface of the adjusting plate 32 has a frosted finish, which prevents the aircraft shell 10 from sliding and allows it to be vertically raised and lowered under the constraint of the bottom guide rod 24 and spring 23. To reinforce the aircraft shell 10 mounted on the base 1, the servo motor 6 at the bottom is activated, rotating the bevel gear... 5 meshing bevel gear 4 forces the screw 3 installed in the base 1 to rotate horizontally. Because the square slots 30 on both sides match the outer edges of the sleeve 8, the sleeve 8 and push plate 9 can be horizontally retracted or pushed out to clamp and fix the aircraft shell 10 from both sides. The column 16 is pre-pulled along the slots 18 on both sides of the top of the back plate 11, and then aligned with the screw hole 17 and screwed in the bolt 19 for reinforcement.
