Embodiment Construction

[0022] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below with reference to the accompanying drawings and through specific embodiments.

[0023] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relationship between various components under a certain posture (as shown in the accompanying drawings). The relative positional relationship, the movement situation, etc., if the specific posture changes, the directional indication also changes accordingly.

[0024] In the present invention, unless otherwise expressly specified and limited, the terms "connected", "fixed" and the like should be understood in a broad sense, for example, "fixed" may be a fixed connection, a detachable connection, or an integrated; It can be a mechanical connection or an electrical connection; it ca...

Abstract

The invention relates to an automatic flexible tooling of a bow-shaped clamping plate type, which is especially used for the positioning and clamping of multi-curvature skin panels of aircraft cabin doors. This design mainly includes the drive mechanism and the actuator; the box seat at the bottom of the rack slides on the guide rail to realize the front and rear movement of the whole machine, and the vacuum suction cup with the support head installed on the front support column and the cantilever completes the adsorption and clamping; The position sensor on the support ball head completes the precise positioning of the skin panel; at the same time, a position sensor, a proportional valve control system and a pressure test system are installed between the hydraulic pump and the hydraulic cylinder to ensure the lifting accuracy. Compared with the prior art, the overall technical solution of the present invention makes the entire flexible tooling system meet the On the premise of positioning and clamping, it is better adapted to the positioning and clamping of multi-curvature skin panels.

Description

technical field [0001] The invention belongs to the technical field of aircraft manufacturing, and in particular relates to a bow-shaped clamping plate type automatic flexible tooling, which is especially used for positioning and clamping of multi-curved wall panels of aircraft. Background technique [0002] The aircraft assembly process involves a large number of thin-walled and weakly rigid assemblies, which have the characteristics of large dimensional outline, large outline variation range, and high dimensional, shape and position tolerance requirements. The wall panel is easily deformed during assembly and processing, which affects the assembly accuracy. Therefore, at present, domestic aircraft manufacturing units mostly use special tooling with rigid structure in the aircraft assembly process to ensure the stability of the assembly quality of different batches of wall panels. However, at this stage, the aircraft design and manufacturing cycle is constantly shortened, ...
