Embodiment Construction

[0041] Aiming at the manufacturing requirements for the assembly of the helicopter's moving parts, the present invention proposes a rotatable combined adjustment device, which can quickly combine and adjust, balance the center of gravity, have a simple structure, convenient operation, and reliable fixation. The rotatable combined adjustment device overcomes the difficulties in the original method of using flexible slings for hoisting and connection, which is not easy to quickly turn over the horizontal balance positioning and adjust the assembly operation, and can conveniently realize rapid balance positioning and telescopic adjustment. To achieve rapid replacement of different types of products, to meet the manufacturing quality and progress requirements of the assembly task of the main propeller hub product.

[0042] see Figure 1-8 A rotatable combined adjustment device provided by the present invention includes: a rotating curved arm 1, a telescopic screw rod 2, a flange a...

Abstract

The invention provides a rotatable combined adjusting device, which comprises a rotating bent arm, a rotating shaft, a rotating shaft, a rotating shaft and a rotating shaft, and is characterized in that the rotating bent arm is provided with a through hole; the positioning shaft is arranged in the through hole and is used for mounting a propeller hub connecting piece; the flange support arm is connected with the rotating bent arm through a telescopic screw rod; the supporting column is rotationally connected with the flange supporting arm; the adjusting bent column is connected with the supporting column through a telescopic screw rod; the lifting lug is arranged on the adjusting bent column; the rotatable combined adjusting device can be quickly combined, adjusted and balanced in gravity center, and is simple in structure, convenient to operate and reliable in fixation.

Description

technical field [0001] The application belongs to the technical field of tooling tools, and in particular relates to a rotatable combined adjustment device. Background technique [0002] The assembly technology of helicopter moving parts directly affects the product quality of helicopters. At the same time, as the assembly tasks of the company's main rotor hub products become more and more heavy, it is urgent to develop a method for positioning and hoisting of helicopter main and tail rotor hub connectors during assembly. , Mobile rotatable combined adjustment device. [0003] At present, when the main and tail rotor hub connectors of various types of helicopters are assembled, the original method adopts the flexible sling hoisting connection form, which is not easy to quickly flip the horizontal balance positioning and adjust the assembly operation. At the same time, it cannot meet the requirements of quickly changing different types of products before and after the hub ass...
