Embodiment Construction
[0020] The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.
[0021] The "front" and "rear" in the present invention are described relative to the working state of the transmission rod. In the working state, the end extending into the inside of the component is the front or front end, and the hand-held end is the rear or rear end.
[0022] refer to figure 1 , in the embodiment of the present invention, the structural features of the gas turbine meet the following conditions, the inner diameter of the connecting nut is not less than 40% of the diameter of the inner cavity of the low-pressure turbine rotor front shaft 14; the inner diameter profile of the low-pressure turbine rotor shaft cavity should be not less than the length of the connecting nut Cylindrical segment.
[0023] The device of the invention can realize the rapid and automatic alignment of the tooling itself and the connecting nut in the axia...

The invention discloses a tool for installing a deep cavity connecting nut. The tool comprises a conveying rod, a nut temporary installation section and a front centering support block; the front centering support block is of a fan-shaped structure, and is rotatably connected with the front end of the conveying rod through a bearing; the nut temporary installation section and the conveying rod arecoaxially installed; the nut temporary installation section is arranged on the rear side of the front centering support block, and is provided with a cylindrical surface; the cylindrical surface is provided with an external thread; the external thread is matched with an internal thread of the connecting nut; and the connecting nut is temporarily installed on the nut temporary installation section. The connecting nut is conveyed to an installation position through the conveying rod, the front end of the conveying rod firstly enters a space coaxial with the installation position of the connecting nut, the front centering support block can always provide support for the front end of the conveying rod, and the other end of the connecting nut can be accurately screwed into a position to be connected, so that the problem of wire hanging caused by blind installation of connection is avoided, and the accuracy and efficiency of installation of the deep cavity connecting nut are improved.
Description
technical field [0001] The invention belongs to the technical field of assembly of mechanical components, and in particular relates to a tool for installing deep cavity connecting nuts. Background technique [0002] In some long cylindrical parts, some connecting nuts are far away from the long axis and are designed in the inner cavity. When installing the connecting nuts, use a long rod tool to extend the nut from the front opening into the cavity of the long cylindrical part. Assembling, because the connecting nut is a self-locking nut, the self-locking device is located inside the connecting nut, the installation space of the connecting nut is small, and the front end positioning cannot be added, so it can only be installed blindly based on experience, which is easy to cause the connecting nut and the low-pressure turbine rotor shaft The bumping of the outer thread of the end will cause thread damage, causing the nut to gradually accumulate thread hanging during the tight...
