The application belongs to the field of aircraft assembly inspection, and in particular relates to a diameter inspection device for thread propulsion, which includes a transmission rod, a main rod body, a rotating column, an upper casing and a lower casing, the upper casing and the lower casing are connected, and the rotating column is located in the transmission In the rod, the transmission rod is located in the main rod body, and the main rod body is located in the upper casing and the lower casing. The outer surface of the main rod body is a cylindrical surface, which is completely fitted with the lower casing and can slide freely. This application greatly improves the variable diameter inspection device, simplifies the manufacturing difficulty of pin parts, the cost of parts, and the complexity of assembly assembly, shortens the assembly cycle of pin assembly by more than 90%, and greatly improves the efficiency of industrial manufacturing. The inspection accuracy is greatly improved and the manufacturing cost is reduced.
Description
technical field [0001] The application belongs to the field of aircraft assembly inspection, and in particular relates to a screw-propelled diameter inspection device. Background technique [0002] Although the device used to check the aperture and coaxiality in the prior art can solve the measurement problems of different apertures and positioning deviations, the following problems exist in the manufacturing and use of the device: [0003] The structure of the device is extremely poor in assembly. It is necessary to pre-embed all the working blocks in the shell, then coordinate the push rod, insert the positioning part of all the working blocks into the push rod slot, and then coordinate the installation of gears and other components. A conventional assembly requires 2- 3 hours, the efficiency is extremely low. [0004] The guide part of the device is incomplete (not a complete cylinder), and when running to the lower end, the push rod has axial shaking, which affects the ...
