Abstract

The invention relates to the technical field of and discloses an internal rounding grinding tool for turbine bearing cylinder blades. The internal rounding grinding tool for the turbine bearing cylinder blades comprises a platform; the top of the platform is provided with a bearing cylinder; the two sides of the bearing cylinder are provided with alignment jackscrews; the top of the bearing cylinder is provided with a rotating motor; the output end of the rotating motor is fixedly connected with a gearbox; the bottom of the gearbox is rotationally connected with a stand column; one side of thestand column is fixedly connected with a lifting screw rod; the outer surface of the stand column is movably connected with a rocker; the front side of the rocker is rotationally connected with a gear; and the front side of the gear is fixedly connected with a driven wheel. According to the internal rounding grinding tool for the turbine bearing cylinder blades, by arranging the alignment jackscrews, the bearing cylinder can be installed conveniently, and stability of the bearing cylinder is enhanced; and by arranging the rotating motor, the gearbox, the stand column and the rocker, the effect of blade rotary rounding can be achieved, and the gearbox can control the rotation speed of the stand column conveniently when the rotating motor drives the stand column to rotate.

Description

technical field [0001] The invention relates to the technical field of turbines, in particular to a tool for grinding the inner diameter circle of blades of a turbine bearing cylinder. Background technique [0002] A turbine is a machine that converts the energy contained in a fluid medium into mechanical energy. Not only compressors, steam turbines, turbines, flue gas turbines, and expanders can all be called turbines. With the increasing social and economic development, turbines The flat machine has been widely used in people's production and life. The use of the turbine machine has greatly improved the production efficiency. When the turbine machine is used, it is necessary to install the air seal of the turbine rotor. [0003] The inside of the turbine is equipped with a supporting cylinder, and the inside of the supporting cylinder is equipped with blades. Since the blades are installed manually, the length of the installed blades is uneven, that is, the inner circle fo...
