Embodiment Construction

[0044] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0045] Figure 1~3 The rotor tenon connection structure locked by the existing lock pin is shown. Such as figure 1 As shown in (a), according to the installation angle of the blade, the tenon connection direction of the rotor blade and the disc usually forms an angle θ with the rotor axis. figure 1 (b) for figure 1 The E-E direction view of (a) shows the two-dimensional shape of a typical rotor tenon connection structure. At the lowest position of the rotor tenon connection structure, there is a groove at the bottom of the blade tenon 2, which can be inserted into the lock pin 3. Used to fix the tenon connection structure of the rotor. In order to ensure the positioning and installation of the lock pin 3, as figure 2 As shown, a tapered surface is...

Abstract

The invention discloses a tool structure used for rotor tenon joint lock pin assembling. The tool structure comprises an assembling tool base, an assembling tool cover plate, a punching riveting pin, an adjusting bolt and the like. The assembling tool base, the assembling tool cover plate and the rotor structure are matched, and tenon structure axial and radial positioning is achieved; and the punching and riveting pin and the adjusting bolt can be adjusted to be axial with the lock pin and abut against a countersunk head of the lock pin based on positioning of the assembling tool base, and the function of the lock pin punching and riveting base is achieved. By means of the tool, centering and axial positioning of a wheel disc can be achieved, and debugging and measuring workloads in the blade and wheel disc assembling process are reduced; only the rotor wheel disc needs to be rotated, the position of the wheel disc on the tool is adjusted with one freedom degree, alignment of the punching and riveting base and the lock pin is achieved, and adjustment is simple and practical; and the punching and riveting base can abut against the lock pin through the fine adjustment adjusting bolt, and the tool is suitable for locking of the multi-blade structure of a rotor. The tool is simple in structure and easy to achieve.

Description

technical field [0001] The invention relates to a lock pin locking assembly tooling structure used for ground gas turbines, aero-engines and other rotors with tenon joints, which can effectively realize the positioning of the tenon head, tenon groove, and lock pin in the tenon joint structure, and meet the tenon joint locking requirements. assembly. Background technique [0002] High-speed rotating rotor structures are widely used in turbomachinery such as ground gas turbines and aero-engines. Due to the limitation of the current processing and casting level, the rotors of medium-sized and large-sized ground gas turbines and aeroengine turbines cannot realize the integrated processing of blades and discs. Blades and discs are usually processed separately and assembled into rotors through tenon joint structures. Turbine mostly adopts fir tree tenon structure, and compressor mostly adopts dovetail tenon structure. There are differences in tooth profiles of tenon structures b...
