Problems solved by technology

However, there is a lack of special metal processing equipment at the maintenance site, which makes it difficult to position the reamer, and the reamed hole will not be perpendicular to the plane of the opposite wheel again, and the workload is relatively large.

Embodiment

[0020] like figure 1 As shown, a cutting device for correcting the non-perpendicularity between the hole and the plane when the opposite wheel is connected includes a positioning shaft 7, a feed cutting mechanism and a vertical reference mechanism, and the feed cutting mechanism and the vertical reference mechanism are installed on the positioning shaft 7, the feeding and cutting mechanism is inserted into the connecting hole of the opposite wheel. When the vertical reference mechanism measures that the connecting hole is not perpendicular to the plane, the feeding and cutting mechanism cuts the connecting hole until the connecting hole is perpendicular to the plane.

[0021] The feed cutting mechanism includes a feed nut 5 sequentially installed on the positioning shaft, a plane bearing 3 and a rotary cutter shaft 1, and the rotary cutter shaft 1 is inserted into the connecting hole of the counter wheel.

[0022] A white steel cutter bar 6 is housed on the described rotary cu...

Abstract

The invention relates to a cutting device for correcting the non-perpendicularity condition of a hole and a plane in coupling connection. The cutting device comprises a locating shaft, a feeding cutting mechanism and a perpendicularity reference mechanism. The feeding cutting mechanism and the perpendicularity reference mechanism are mounted on the locating shaft, and the feeding cutting mechanism is inserted into a coupling connecting hole; and when the perpendicularity reference mechanism measures that the connecting hole is not perpendicular to the plane, the feeding cutting mechanism cuts the connecting hole until the connecting hole is perpendicular to the plane. Compared with the prior art, the cutting device has the advantages of being convenient to operate, low in labor intensity, high in efficiency and the like.

Description

technical field [0001] The invention relates to a cutting device, in particular to a cutting device for correcting the non-perpendicularity between the hole and the plane when the pairing wheels are connected. Background technique [0002] After each inspection and centering of the 300MW steam turbine shafting system in our factory, the pin bolt holes of the opposite wheel connecting the shafting system must be reamed, and then the pin bolts are arranged according to the actual hole diameter, so as to ensure the stability of the shafting center. In the process of reaming, due to inaccurate positioning or excessive reaming, the axis of the reamed hole is not perpendicular to the plane of the opposite wheel, and the pressure surface of the pin bolt is formed by the contacting pressure surface of the opposite wheel. An included angle, when the pin bolt is locked, it will generate radial thrust with the counter wheel, and the counter wheel will have a radial displacement, which ...
