At present, the large-scale aircraft digital assembly system mainly comprises an adjustment object (aircraft products to be docked), a three-coordinate numerical control positioner, a measurement system, an integrated management system, a control system and the like. Four three-coordinate numerical control positioners form a large-scale aircraft adjusting system and are uniformly distributed at the lower part of an aircraft body, so that the reliable support and pose adjustment of an adjusting object can be realized. Therefore, the three-coordinate numerical control positioner is used as an important component of the aircraft digital assembly system, and the installation positioning accuracy of the three-coordinate numerical control positioner directly determines the stress distribution influence of the aircraft digital assembly system on the whole structure of the adjustment object.
The traditional locator mounting mode adopts a foundation embedded steel plate, and the locator base is fixed in a pin positioning and bolt connection mode. Because the main body of the numerical control locator is made of cast iron, the numerical control locator has the characteristics of large volume, heavy weight and the like. In the installation process, the relative positions of the numerical control locators are difficult to adjust in place in the horizontal plane, and the installation accuracy cannot be guaranteed. Due to the influence of the traditional installation form, in the adjustment process of an adjustment object (airplane product to be docked), stress caused by installation of the numerical control positioner tends to exist on a horizontal plane (namely in the X/Y direction), so that the adjustment object generates multidirectional stress deformation to a certain extent. Therefore, it is urgent to provide a stress-free positioning structure for positioning and installing a numerical control positioner.
