Abstract

The invention discloses an assembly device of a casing threaded pin, and belongs to the technical field of aircraft engine assembly. The assembly device of the casing threaded pin comprises a fixing frame and an assembly component, the fixing frame comprises a first limiting block and a second limiting block which are arranged in a spaced mode, the first limiting block is provided with a positioning hole, the second limiting block is provided with a threaded hole, the assembly component comprises a connecting rod and an ejector rod, the connecting rod penetrates through the second limiting block and is in threaded connection with the second limiting block, the ejector rod penetrates through the connecting rod and faces the positioning hole, and the ejector rod is in threaded connection with the connecting rod. According to the assembly device, the threaded pin and a casing can be quickly and accurately positioned, so that the threaded pin and a bottom hole of the casing can be rivetedquickly through the ejector rod, in addition, the ejector rod carries out extrusion movement through threads, the pressure of a screw pair is strong, assembly can be carried out stably, and the assembly quality is high.

Description

technical field [0001] The invention relates to the technical field of aero-engine assembly, in particular to an assembly device for threaded pins of casings. Background technique [0002] The casing is the basic structural unit of an aero-engine. It is divided into many sections connected to each other. It is generally a circular piece with a large volume and a large diameter. It is necessary to install various accessories, small parts and ensure that the sections of the receiver are connected together. Since the casing is made of aluminum alloy and the material is soft, it is required to drill the bottom hole on the base and then press in different alloy steel threaded pins according to different functions to improve the thread strength to meet various connection needs. Fitters must use suitable tools to assemble threaded pins to ensure that the pressed threaded pins are connected reliably without loosening and meet various technical requirements. Due to the variety of s...
