Abstract

The invention discloses a connecting device for rotors and indexing monitoring equipment for machining wheel grooves of the rotors of steam turbines, and relates to a connecting device. The connecting device is used for solving problems of long time consumption and high labor consumption and service cost of an existing indexing disc during usage. The connecting device comprises a first cylinder section (1), a circular truncated cone section (2), a second cylinder section (3), a fourth cylinder section (4) and a fifth cylinder section (5) which are axially, sequentially and fixedly integrated. One end of the first cylinder section (1) is fixedly connected with a small end of the circular truncated cone section (2), one end of the second cylinder section (3) is fixedly connected with a large end of the circular truncated cone section (2), external threads are machined on the first cylinder section (1) along the length direction of the first cylinder section (1), and two rectangular platforms (3-1) are symmetrically machined on the second cylinder section (3). The connecting device is used for connecting the rotors with the indexing monitoring equipment for machining the wheel grooves of the rotors of the steam turbines.

Description

technical field [0001] The invention relates to a connection device, in particular to a connection device between an indexing monitoring device for machining a wheel groove of a steam turbine rotor and a rotor. Background technique [0002] In the process of rotor wheel groove processing, in order to ensure the accuracy of rotor indexing and avoid major quality accidents caused by indexing errors, it is necessary to install an indexing monitoring device on the rotor adjustment end side to ensure the accuracy of rotor indexing. accuracy. The existing connection indexing plate positioned by the inner and outer spigots of the rotor, the connection indexing plate is processed and used to customize different tooling connection plates according to the size of different products, which is time-consuming and labor-intensive during use. The input of use cost. Contents of the invention [0003] In order to solve the problems of time-consuming and labor-intensive use and high cost ...
