Abstract
The utility model relates to a rotor butting flange reaming device for a steam turbine, and aims to solve the problems of large unit vibration and unit damage caused by the fact that reaming is required to be performed on site when two rotor flange holes are butted, the reaming is time-consuming and labor-consuming and the reaming quality is not good in the prior art. The device comprises a spindle box, a reamer, a feeding mechanism and a fixing mechanism, wherein the feeding mechanism comprises a screw rod, a support and a crank handle; the fixing mechanism comprises two first semi-circle rings and two second semi-circle rings; the lower end of a fixing block is arranged on the screw rod; the reamer is mounted on a spindle in the spindle box; the crank handle is fixedly connected with one end of the screw rod; the first semi-circle rings are mounted on the lower surface of the support; and the first semi-circle rings and one second semi-circle ring are mounted on a rotor. The rotor butting flange reaming device for the steam turbine is used for butting connection of the steam turbine unit rotor flanges.
Description
Technical field
The utility model relates to a kind of turbine rotor to wheel flange reaming device.
Background technology
When steam turbine two roots rotor flange holes dock with flange hole, to wheel bolt hole, need artificial scene to carry out reamer bolt hole with reamer holder scene, waste time and energy, (20 to 30 days at least fraising time) is subject to the restriction of Venue Operations space-constrained simultaneously, artificial processing ease occurs that discontinuity is easy to make bolt hole hinge partially, and the bolt hole fineness that requirement is cut with scissors out is high again, if there is excesssive gap in the poor quality to bolt hole fraising, when unit operation, cause unit vibration large, in power plant, also once repeatedly occurred, cause harmful effect also to steam turbine quality, improve steam turbine product quality, manufacturer also also all attaches great importance to this work for this reason.
Utility model content
The utility model needs scene to ream when solving in prior art two roots rotor flange holes docking, fraising is wasted time and energy, and the poor quality of fraising causes unit vibration large, damage the problem of unit, and then provide a kind of turbine rotor to wheel flange reaming device.
The utility model is to address the above problem the technical scheme adopting to be: described device comprises main spindle box and reamer, described device comprises feed mechanism and fixed mechanism, feed mechanism comprises leading screw, bearing and wind, fixed mechanism comprises two the first semicircular ring and two the second semicircular ring, the lower surface of main spindle box is provided with fixed block, leading screw is arranged in bearing, main spindle box is arranged on bearing, the lower end of fixed block is arranged on leading screw, reamer is arranged on the main shaft in main spindle box, wind is fixedly connected with one end of leading screw, the lower surface of bearing is provided with two the first semicircular ring, each first semicircular ring and a second semicircular ring spiral-lock are on rotor.
The beneficial effects of the utility model are: pass through the utility model, when rotor is reamed to wheel flange by the utility model, improved the operating efficiency of fraising, use the utility model only to need just can complete for three hours the work that wheel flange is reamed, hole fineness after processing by reamer is high again, work quality has had large increase, avoid the generation of unit generation vibration damage unit phenomenon, the utlity model has feature simple in structure, easy to use.
