Embodiment 1

[0042] Embodiment 1: as figure 1 The hat-shaped truss overall positioning device shown in the figure includes two parts: a plurality of aluminum alloy positioning clamp assemblies 2 with clamping devices and an overturn frame 1 welded by rectangular steel. The positioning clamp assembly 2 is based on the product structure Size, the quantity can be 2 to 20 pieces, and the segmented positioning and segmented normal clamping of the hat-shaped stringer can be realized according to the structural size of the product.

[0043] The overturning frame 1 has an overturning shaft 101 and a positioning guide post 102, a suspension ring 103 and a suspension ring 104 for lifting the device, a multi-channel crossbeam 105 for ensuring the structural rigidity of the device and for installing the positioning clamp assembly, and when the device is turned over Turning support feet 106 supported on the ground or platform.

[0044] The multi-channel beams 105 are made of square steel, and are welded

Abstract

The invention discloses a cap type stringer integral positioning device which comprises an overturning frame, overturning shafts are arranged at the two ends of the overturning frame respectively, a plurality of cross beams are arranged in the overturning frame, and the bottoms of the cross beams are connected with positioning clamping plate assemblies through connecting plates and clamping plate connecting pieces. The positioning clamping plate assembly comprises a clamping plate body, clamping devices and guiders, clamping positioning grooves with the number consistent with that of the cap-shaped stringers are formed in the clamping plate body along the arc-shaped bottom edge, and the clamping devices and the guiders with the number consistent with that of the cap-shaped stringers are arranged on the clamping plate body. According to the cap-shaped stringer integral positioning device, the combination efficiency and the positioning precision of the cap-shaped stringer and the skin are improved, and by means of the device and the method, the cap-shaped stringer can be integrated on the cap-shaped stringer integral positioning device firstly; through overturning of the overturning positioning frame, the whole device for loading the cap-shaped stringer and a skin mold are integrally and accurately combined at a time by utilizing a travelling crane, and the cap-shaped stringer can be integrally shaped, clamped, overturned and accurately positioned and assembled on the skin.
