A rotary multi-station paddle beam with winding mandrel workbench

Abstract

The invention discloses a rotary multi-station paddle girder belt winding mandrel workbench which comprises a base, a multi-station rotary mechanism, an auxiliary supporting mechanism and a rotary operation mechanism. The form of winding mandrel multi-station transformation is adopted, multiple winding mandrels are mounted on the multi-station rotary mechanism, station transformation is achieved through transposition of the winding mandrels, the links of manual clamping, dismounting and carrying are omitted, and the work efficiency is improved. The high-rigidity multi-station rotary mechanism is adopted, and is suitable for clamping of the long winding mandrels. The auxiliary supporting mechanism is arranged at the bottom of the middle of the workbench so that it can be guaranteed that during operation, no deformation happens, or deformation is controlled within a reasonable range, and the winding precision can be ensured. By means of simple manual operation of handle and plug locating and the like, transformation between all the stations is achieved, and the labor intensity of workers is lowered.

Description

technical field [0001] The invention belongs to the technical field of fiber winding, and relates to a winding mandrel workbench suitable for winding and forming of helicopter composite blade girder belts. Background technique [0002] Filament winding molding refers to winding the fiber prepreg tape on the winding mandrel with a special shape according to the design rules, and then through subsequent treatments such as curing and cutting, to finally obtain a shaped component of a specific shape. Its products have a series of advantages such as high specific strength, large specific modulus and good fatigue resistance. [0003] Helicopter composite blade girder belt is a fiber-reinforced composite component, which is the main load-bearing unit in the aircraft rotor system, and can be made by filament winding molding technology. Due to the limitation of the internal space of the blade, the shape of the girder belt is designed as a slender and complex spatial geometry. [00...

AI Technical Summary

Problems solved by technology

[0006] (1) The shape of the winding mandrel is long and thin, with large length and low rigidity, and it is easy to deform during long-term reciprocating handling, which affects the winding accuracy;

[0007] (2) When the winding mandrel is replaced, it is necessary to manually remove the winding mandrel and reinstall a new winding mandrel. The operation is cumbersome and the process preparation time is long, which affects the overall work efficiency;

[0008] (3) At least two workers are required to cooperate to realize the handling of the large-length winding mandrel, which is labor-intensive
