[0014] The beneficial effects of the present invention: The embodiments of the present invention provide an assembly device and method for a metal bonding platform. A skeleton locator 3 is installed on the mounting frame at the front end of the assembly device. Holes are drilled on the skeleton locator 3 using an assembly mounting hole drilling jig assembly. A joint drilling jig locator 8 is installed on the front end face of the movable frame that can slide on the slide rail assembly 7.

[0015] The accompanying drawings are provided to further understand the technical solutions of the present invention and constitute a part of the specification. They are used together with the embodiments of this application to explain the technical solutions of the present invention and do not constitute a limitation on the technical solutions of the present invention.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0018] As explained in the background section above, the assembly quality of the helicopter main reduction platform components during the sub-assembly stage directly affects the installation of key components such as the main reducer during the final assembly stage. Furthermore, the assembly of the main reduction platform components is a key control item in helicopter structural assembly, characterized by complex assembly relationships, high coordination difficulty, and high quality requirements.

[0019] The main technical problems to be solved are as follows: 1) The lower end of the metal adhesive platform is connected to the main frame formed by the frame skeleton and beam skeleton, and the upper end is connected to the main reduction suspension joint and the main reduction strut joint. It is an important component of the main reduction platform. Due to the high temperature curing of the metal adhesive platform, the platform has poor flatness after molding, and the stress is mainly concentrated at the corners. The measured maximum warping of the installation surface in the connection area of ​​the main reduction suspension joint and the main reduction strut joint is 0.6mm, which seriously affects the accuracy of the docking position of the main reduction suspension joint and the main reduction strut joint. It is necessary to eliminate the flatness deviation of the metal adhesive plate by optimizing the assembly process; 2) Due to the influence of the structure, the existing platform positioner interferes with the drilling template of the main reduction suspension joint and the main reduction strut joint. The hole size accuracy, hole position accuracy, and inter-group hole position accuracy of the main reduction suspension joint and the main reduction strut joint are high. The accuracy and stability of the drilling template cannot be guaranteed when disassembling and assembling.

[0020] To meet the manufacturing requirements of high precision, long life, and high reliability of helicopter main reduction platform components, it is crucial to study the assembly methods during the sub-assembly stage. This invention provides an assembly device and method for a metal bonding platform. By developing an assembly device that integrates functions such as assembly hole and surface assurance and inspection, the forming and assembly errors of the metal bonding platform and parts such as frames and beams are eliminated, thereby improving the assembly quality and efficiency of helicopter main reduction platform components.

The four edges of the metal bonding platform are tightly pressed by using the forceps, so as to ensure the flatness of the fitting surface of the metal bonding platform and the main reduction suspension hanger joint and the main reduction support rod joint.

[0035] (2) Position the installation positions of the main frame (including the frame skeleton and the beam skeleton) and the reinforcing structure on the metal bonding platform by using the assembly device.

[0036] The end surface of the metal bonding platform in the vertical direction (i.e. the Z direction) is always fitted with the positioning profile of the platform positioner 2. The installation positions of the frame skeleton, the beam skeleton, the corner box, the angle bar, the belt plate and the like in the main frame on the metal bonding platform are positioned in sequence by using the skeleton positioner 3.
