Multi-degree-of-freedom grabbing and conveying device for special-shaped component of aviation aircraft landing gear

Abstract

The invention provides a multi-degree-of-freedom grabbing and conveying device for a special-shaped component of an aviation aircraft landing gear. The multi-degree-of-freedom grabbing and conveying device comprises a full-electric lifting walking vehicle, a two-dimensional fine adjustment mechanism, a shaft rotating mechanism, a posture-adjustable clamping mechanism and a hydraulic system, wherein the two-dimensional fine adjustment mechanism is arranged on the full-electric lifting walking vehicle through an X-Y machine base, and the shaft rotating mechanism is arranged on the two-dimensional fine adjustment mechanism; and the posture-adjustable clamping mechanism is arranged at the output end of the shaft rotating mechanism. The full-electric lifting walking vehicle drives the two-dimensional fine adjustment mechanism to walk and ascend and descend in the Z-axis direction, and the two-dimensional fine adjustment mechanism achieves X-axis and Y-axis displacement adjustment. The shaft rotating mechanism drives the posture-adjustable clamping mechanism to rotate by 360 degrees in the space, the posture-adjustable clamping mechanism horizontally grabs or vertically grabs the special-shaped component, and the hydraulic system drives the posture-adjustable clamping mechanism to act. According to the multi-degree-of-freedom grabbing and conveying device, manpower resources can be greatly saved, self-walking and multi-angle grabbing without site limitation is achieved, posture transfer is freely adjusted according to requirements, and an external power source does not need to be arranged.

Description

technical field [0001] The invention belongs to the field of aviation mechanical equipment, and in particular relates to a multi-degree-of-freedom grasping and conveying device for special-shaped components of aircraft landing gear. Background technique [0002] With the rapid development of science and technology and the continuous improvement of production levels, people have higher and higher requirements for labor intensity and working environment. Petrochemical, food, military machinery and other industries have higher and higher requirements for handling quality and efficiency. However, the inefficient manual handling has hindered the increase of the output of these industries, which can no longer meet the needs of production, thus promoting the transformation of enterprises to modernization. At present, most of the domestic automatic handling equipment are imported products, and there are relatively few domestic equipment manufacturers. The technology of handling robo...

Problems solved by technology

After maintenance, the components are assembled and tested through multiple processes. There are many maintenance processes, the distance between the stations is long, there are multiple channels to shuttle, and the terrain is complex. It is not suitable to set up an external power source. This is the current situation of most maintenance manufacturers in my country.

After the parts test is completed, the parts need to be assembled in a centralized assembly station. During the assembly process, complex structural parts need to change angles and work steps for precise assembly. After assembly, the landing gear needs to undergo multiple comprehensive experiments. According to the requirements of use, the landing gear is transported to various laboratories and various testing machines are accurately positioned at multiple angles. During the period, manual transfer and positioning are required. The labor intensity of the staff is high, and multiple people are required to work together. For larger and heavier parts, it is very easy to cause labor. damage, inevitably causing economic losses, and even casualties

However, due to the uncertain factors in the human operation process, the positioning time of the aircraft landing gear during assembly and testing varies, which prolongs the positioning time and reduces work efficiency.
