Abstract

The invention discloses an automatic large engine part butting device, and belongs to the technical field of engine assembly. The butting device comprises a motion butting bracket assembly, a gesture adjusting bracket assembly, an image measurement assembly, a laser ranging sensor assembly, an inclination angle sensor assembly, a stepper motor assembly and a computer control assembly. Through reasonable design, mounting and matching of the above assemblies, measurement data of the image measurement assembly, the laser ranging sensor and the angle sensor are acquired and processed by the computer control assembly; motion control is carried out on the stepper motor motion assembly; and automatic gesture adjusting and butting of two sub parts of the large engine part in the space six-degree of freedom can be realized on the gesture adjusting bracket assembly and the motion butting bracket assembly. Development requirements on efficient and precise butting of large parts during the engine development and production process can be met.

Description

technical field [0001] The invention relates to the technical field of engine assembly, in particular to an automatic docking device and a docking method for large parts of an engine. Background technique [0002] The large part of the engine is formed by the butt assembly of two independent sub-parts, the combustion chamber and the fuel tank, and is one of the important links in the process of engine development and production. The existing docking device is a simple mechanical docking tool, which completely relies on manual visual inspection and manual adjustment to complete the docking. [0003] Since the docking of two sub-components is a six-degree-of-freedom composite adjustment process of three-dimensional movement in space and rotation around the axis, and there are also requirements such as high docking accuracy and one-time success, currently the docking of large parts relies on simple support tooling, manual adjustment, The human eye is aimed at the mechanical do...
