A multi-axis mechanical arm for cutting the end face margin of aircraft fuselage skin

Abstract

The invention discloses a multi-axis mechanical arm for cutting the margin of the skin end surface of an aircraft fuselage, which comprises an inner frame, a rotating belt is arranged at the inner center of the inner frame, an installation frame is arranged on the upper surface of the middle part of the outer frame, and the installation frame The inner lower end surface of the outer frame is fixedly installed with a block, the first motor is installed on the left upper surface of the outer frame, and the upper side of the first motor is connected with a connecting belt, the upper left end of the outer frame is provided with a hydraulic pressure device, the right side of the top plate The outer side is covered with movable blocks, the lower end of the support column is internally connected with a connecting column, the middle and upper side of the support column is covered with a sleeve plate, and a horizontal plate is installed on the right side surface of the sleeve plate, and a straight line is arranged on the upper surface of the horizontal plate. For the motor, a second motor is installed inside the bottom frame, a fixing frame is arranged on the right upper surface of the outer frame, and a rotor is connected to the right side surface of the third motor. The multi-axis mechanical arm for cutting the end face margin of the aircraft fuselage can process raw materials of different sizes, and can fix the raw materials during the working process.

Description

technical field [0001] The invention relates to the technical field of aircraft fuselage skin manufacturing, in particular to a multi-axis mechanical arm for cutting the end surface allowance of the aircraft fuselage skin. Background technique [0002] Aircraft skin refers to the three-dimensional component that surrounds the frame structure of the aircraft and is fixed on the frame with adhesives or rivets to form the aerodynamic shape of the aircraft. The skin structure composed of aircraft skin and skeleton has a large bearing capacity and rigidity, but its own weight is very light, and plays the role of bearing and transmitting aerodynamic loads. Early or low-speed small aircraft used cloth as the skin. At this time, The skin can only bear part of the limited aerodynamic load and does not participate in the overall force. The common skins of the current aircraft include metal skins, composite laminated skins, sandwich skins and integral wall panels. [0003] In the exis...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a multi-axis mechanical arm for cutting the end face margin of the aircraft fuselage, which solves the problem that the existing multi-axis mechanical arm cannot adjust its own position, resulting in The device can only process a fixed position, and it cannot guide the position of the raw material during use, and it is easy to cause the problem that the clamping of the raw material is not accurate enough
