Abstract

The invention relates to a press-in bushing installation tool. A support sleeve is provided on the stepped guide shaft passing through the lug of the part. One end of the support sleeve is supported on the limit platform of the guide shaft, and the other end is supported on the part ear. The end surface of the piece, and the support sleeve is provided with a groove, the diameter of the groove is consistent with the diameter of the through hole of the part lug; a pressure sleeve is formed at the end where the guide shaft passes through the part lug, and one end of the pressure sleeve is formed with the part to be installed. The bush contacts, and the other end contacts with the nut, and the front end of the guide shaft is provided with an external thread, and the nut is threaded with the external thread; a handle passing through the guide shaft is provided at the rear end of the guide shaft. The tool uses the clamping force generated when the nut is tightened to press the bushing into the product to complete the installation of the bushing, which does not damage the bushing and meets the installation accuracy requirements.

Description

technical field [0001] The invention relates to a press-in bushing installation tool and a using method thereof, belonging to the field of high-precision bushing installation auxiliary tools. Background technique [0002] A pair of finished bushings must be installed on the suspended center beam wing lug joints, and the original precision of the bushings must not be damaged during the installation process. At the same time, the coaxiality and verticality of the bushing holes after installation must be controlled within a certain range of accuracy. Inside, this poses a great challenge to the installation of the bushing. At present, for the installation of high-precision bushings in the aviation industry, the semi-finished bushing is generally installed into the target hole with a gun, and then the semi-finished bushing is subjected to secondary processing such as expansion and reaming to achieve the required accuracy; or liquid nitrogen is used to shrink the bushing. The met...
