Embodiment Construction

[0027] A positioning device for flexible multi-point forming of wall plate parts, the positioning device is composed of two parts: a fixed end constraining module 12 and a moving end constraining module 11. Specifically include:

[0028] Fixed end constraint module 12: The ball head positioning pin 8 on the top of the module is connected to the fixed end base 6 through a spherical pair, and the ball head positioning pin 8 cooperates with the positioning hole on the part 1 to restrict the part 1 in two directions in the installation plane degrees of freedom of movement.

[0029] Mobile end constraint module 11: This module is composed of mobile end base body 4, screw 9, and rotating positioning pin 2. The rotating positioning pin 2 can rotate along the axis of the screw 9, and the rotating positioning pin 2 cooperates with the positioning hole on the part to restrict the part 1 rotational degrees of freedom in the mounting plane.

[0030] The bottom structure of the base body...

Abstract

The invention relates to a wall board part flexile multi-point forming positioning device. The pin hole positioning manner is adopted, positioning is simple, a positioning pin of a positioning device can adapt to part deformation in the wall board forming process, certain-angle rotation is carried out, on the premise that positioning precision is ensured, deformation stress is not generated, and wall board forming precision is ensured. A positioning device is modular, detaching is facilitated, the positions can be replaced according to different parts, positioning of parts of different sizes can be achieved, operation convenience is improved, and production efficiency is improved.

Description

technical field [0001] The invention relates to a positioning method for flexible multi-point forming of wallboard parts, in particular to the forming of integral wallboard parts with ribs, and belongs to the field of aviation manufacturing engineering. Background technique [0002] With the rapid development of my country's aircraft manufacturing industry, the multi-point forming method has been gradually applied to the forming of sheet metal. The envelope surface formed at the head end is formed instead of the solid mold. In the field of aviation manufacturing, integral wall panels are increasingly widely used due to their outstanding advantages such as high structural efficiency, light weight, good rigidity, and long fatigue life. Due to the complex shape and difficult forming of wall panel parts, flexible multi-point molds have gradually It has been applied in the forming of integral wall panels and skins. [0003] Patent CN104646475A discloses a multi-point forming met...
