Description

Technical Field

[0001] The invention relates to aircraft wheel maintenance equipment, in particular to an aircraft wheel automatic assembly system. Background Art

[0002] As the scale of aircraft wheel maintenance continues to grow, the existing manual maintenance model for aircraft wheels is impacted by human factors, leading to a decline in aircraft tire repair quality and an increasing number of rework inspections. Furthermore, it is impossible to significantly improve manual work efficiency and is unable to meet the current high production volume demands.

[0003] In current aircraft maintenance, the last step is the assembly of aircraft wheels. Currently, manual wheel assembly has problems of low work efficiency and low maintenance quality, which need to be improved. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in current aircraft wheel maintenance equipment, the present invention provides an automatic assembly system for aircraft wheels, which can achieve the effects of improving assembly efficiency and improving maintenance quality.

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

[0006] An automatic assembly system for aircraft wheels, comprising:

[0007] Tire assembly machines for securing aircraft wheel hubs and pre-assembly of aircraft wheels;

[0008] Vision positioning equipment, used to locate the assembly position of aircraft wheels;

[0009] Terminal processing equipment for assembling and connecting the various components of pre-assembled aircraft wheels;

[0010] Robotic arms, used to move terminal processing equipment;

[0011] Controller, used to control the movement of the robotic arm and the operation of the terminal processing equipment;

[0012] The terminal processing equipment is installed on the mobile terminal of the robotic arm.

[0013] According to one aspect of the present invention, the tire assembly machine includes a horizontal motion device, a drive device mounted on the horizontal motion device, a chuck mounted on the drive device, and a clamping device mounted on the chuck. The horizontal motion device is used to control the movement of the chuck relative to a robotic arm, the drive device is used to control the rotation of the chuck, and the clamping device is used to control the horizontal degrees of freedom of the aircraft wheel hub. The horizontal motion device can be used to move the aircraft wheel toward or away from the robotic arm, facilitating robotic processing. The drive device can be used to rotate the chuck, effectively reducing the required degrees of freedom of the robotic arm. The clamping device can be used to limit the degrees of freedom of the wheel hub, preventing it from bouncing during assembly, thereby effectively improving assembly quality.

[0014] According to one aspect of the present invention, at least two tire assembly machines are provided. One of the tire assembly machines is used for automated wheel assembly by the robotic arm and its terminal processing equipment, while the other tire assembly machines are used for pre-assembly of aircraft wheels. By providing more tire assembly machines, the robotic arm and its mobile terminal processing equipment can simultaneously perform pre-assembly of aircraft wheels while assembling a single aircraft wheel, effectively improving the assembly efficiency of the assembly system.

[0015] According to one aspect of the present invention, the horizontal movement device includes a base, a guide rail disposed on the base, and a processing platform slidably connected to the base via the guide rail. The drive device and the chuck are both disposed on the processing platform. The base and the guide rail cooperate to define the movement direction of the processing platform and equipment mounted on the processing platform, ensuring that the processing platform can be moved to a predetermined position.

[0016] According to one aspect of the present invention, the drive device includes a motor and a rotating shaft with one end disposed at the motor's power output terminal, and the chuck is disposed at the other end of the rotating shaft. The motor drives the rotating shaft to rotate, which in turn drives the chuck to rotate. This reduces the machining requirements for the robot arm's degrees of freedom and improves wheel assembly efficiency.

[0017] According to one aspect of the present invention, the chuck is provided with a joint that cooperates with an interface on the hub of the aircraft wheel, so that the clamping device can clamp the aircraft wheel easily via the joint.

[0018] According to one aspect of the present invention, the clamping device includes a clamping shaft positioned at the center of a chuck, a spring plate positioned at the lower center of the clamping shaft, and a clamping plate positioned above the spring plate. The clamping plate is mounted on the clamping shaft and threadedly connected to the clamping shaft. The threaded connection of the clamping plate to the clamping shaft enhances the stability of the clamping device in clamping the aircraft wheel hub.

[0019] According to one aspect of the present invention, the terminal processing equipment includes a torque gun, and the torque gun is used for bolt connection.

[0020] According to one aspect of the present invention, a roller is provided at the bottom of the processing platform, and the bottom of the roller is tangent to the base. The roller can improve the stability of the processing platform and the equipment arranged on the processing platform.

[0021] According to one aspect of the present invention, the robotic arm is a seven-axis robotic arm.

[0022] Advantages of the present invention:

[0023] The present invention discloses an automatic assembly system for aircraft wheels, which comprises: a tire assembly machine for fixing the aircraft wheel hub and pre-assembling the aircraft wheel; a visual positioning device for positioning the assembly position of the aircraft wheel; a terminal processing device for assembling and connecting various components of the pre-assembled aircraft wheel; a mechanical arm for moving the terminal processing device; a controller for controlling the movement of the mechanical arm and the operation of the terminal processing device; the terminal processing device is installed on the mobile terminal of the mechanical arm. The present invention automates or semi-automates the assembly of the aircraft wheel through the mechanical arm and the terminal device processing located on the mobile terminal of the mechanical arm, thereby greatly improving the assembly efficiency of the aircraft wheel. The auxiliary installation of the visual positioning device can improve the assembly quality of the aircraft wheel and the maintenance efficiency of the wheel. BRIEF DESCRIPTION OF THE DRAWINGS
