Abstract
A radial pin 2 has a second end portion 2B protruded from an outer surface of a turbine casing 1 and a first end portion 2A inserted into a through hole 3 formed in the turbine casing 1, and a weld bead 4 is formed on a periphery of the second end portion 2B. A weld bead cutting device 10 has a cutting portion 12 which cuts the weld bead 4 formed on the periphery of the radial pin 2, and a support portion 20 which supports the cutting portion 12 on an end surface 2C of the second end portion 2B of the radial pin 2 such that the cutting portion 12 is movable along the periphery of the radial pin 2.
Claims8
A weld bead cutting device for cutting a weld bead formed on a periphery of one end portion of a pin having the one end portion protruded from a surface of a structure and the other end portion inserted into a hole formed in the structure, comprising:
- a cutting unit which cuts the weld bead formed on the periphery of the pin;
- and
- a support unit which supports the cutting unit on an end surface of the one end portion of the pin such that the cutting unit is movable along the periphery of the pink wherein the support unit includes:
- a fitting member configured to be fitted over and locked by the one end portion of the pin;
- and
- a coupling member which is configured to be pivotable with respect to the fitting member and to which the cutting unit is attached;
- a support shaft provided to stand on the end surface of the one end portion of the pin;
- and
- a bearing provided between the coupling member and the fitting member which supports the coupling member such that the coupling member is pivotable about the support shaft relative to the fitting member.
