Abstract

The invention discloses a vacuum adsorption type three-coordinate flexible attitude-adjusting unit which comprises a base seat, an X direction ballscrew, an X direction reducer, an X direction servo motor, longitudinal and cross plankers, an upper planker, a supporting cylinder body, a telescopic column, a clamping sleeve, a vaccum adsorption ball-end, a Z direction ballscrew, a Z direction grating ruler, a worm gear reducer, a Y direction guide rail slide, a Y direction linear guide, an X direction organ cover, an X direction linear guide, an X direction guide rail slide, a Y direction ballscrew, a Y direction organ cover, a Z direction servo motor, a Y direction reducer and a Y direction servo motor; the closed-loop control is carried out through the driving of the servo motor and the ballscrew and the feedback of the grating ruler, the accurate positioning in the X, Y and Z directions is realized, and the organ cover is arranged in the corresponding direction for protecting. The component part with complex profile can be supported and fixed through the vacuum adsorption, the supporting is steady and reliable, and the cooperative motion can be realized in the three directions. By adopting the vacuum adsorption type three-coordinate flexible attitude-adjusting unit as the core unit, the attitude-adjusting systems for different purposes can be formed through certain configuration.

Description

technical field [0001] The invention relates to a vacuum adsorption type three-coordinate flexible attitude adjustment unit. Background technique [0002] In the assembly process of large parts with curved surface and thin-walled parts, it is faced with the problem of how to adjust them to the target posture and keep the posture unchanged. Most of these components with complex profiles have strict aerodynamic shape requirements, and it is very difficult to design and manufacture support and attitude adjustment tooling to ensure that the design shape remains unchanged. Such parts usually have greater flexibility and are prone to deformation. In order to reduce deformation, traditional tooling equipment is often rigidly supported in multiple positions. During the attitude adjustment process, the attitude is adjusted manually in multiple positions, which requires repeated adjustments. It can only ensure the correct posture of a few necessary matching parts, the workload of pos...

AI Technical Summary

Problems solved by technology

Most of these components with complex profiles have strict aerodynamic shape requirements, ensuring that the design shape remains unchanged makes the design and manufacture of support and attitude adjustment tooling very difficult

Such parts usually have greater flexibility and are prone to deformation. In order to reduce deformation, traditional tooling equipment is often rigidly supported in multiple positions. During the attitude adjustment process, the attitude is adjusted manually in multiple positions, which requires repeated adjustments. It can only ensure the correct posture of a few necessary matching parts, the workload of posture adjustment is heavy, the posture adjustment cycle is long, the efficiency is low, and assembly stress is easy to occur

Such traditional tooling equipment can only satisfy a single or a small number of similar parts

When the production is transformed, it is necessary to redesign the process equipment, resulting in the disadvantages of single use of equipment, long design cycle, high production cost, etc., and requires a large number of assembly personnel, auxiliary lifting mechanism, handling tools, etc.

[0003] Large thin-walled parts and complex-shaped parts, such as aircraft wings, wing panels, etc., due to their complex shape and strict requirements on the shape, it is difficult to install transitional support process joints on the surface, making it difficult to clamp
