Problems solved by technology

Since the workbench of the vertical lathe can only rotate around the Z axis, and the gantry can only move horizontally along the X axis, it is difficult to control the distance between the boss and the rotary axis of the workbench and the eccentric boss when placing the eccentric boss. The angle of the table placement makes the processing difficult

Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] figure 1 It is a structural schematic diagram of a gas turbine casing. Such as figure 1 As shown, the casing includes a casing body 20 and a plurality of eccentric bosses 21, and the casing body 20 is cylindrical. A plurality of eccentric bosses 21 are disposed on the outer wall of the casing body 20 . figure 2 yes figure 1 A-A sectional view of . Such as figure 2 As shown, a plurality of eccentric bosses 21 are distributed at intervals along the circumferential direction of the casing body 21 , and the eccentric bosses 21 are connected to the casing body 20 by welding. Since the eccentric boss 21 is usually processed by a vertical lathe, when the eccentric boss 21 is clamped on the rotary table of the vertical lathe, in...

Abstract

The invention discloses a positioning tool for an eccentric boss of a gas turbine casing, and belongs to the technical field of gas turbine product mechanical manufacture. The positioning tool comprises a base, a positioning plate, a connection assembly, a first telescopic rod and a second telescopic rod. The base comprises a centering rod. One end of the first telescopic rod is hinged to the centering rod. The first telescopic rod is perpendicular to the centering rod. The other end of the first telescopic rod is connected with the connection assembly. One end of the second telescopic rod isconnected with the connection assembly, and the other end of the second telescopic rod is perpendicularly connected with the positioning plate. The second telescopic rod is perpendicular to the firsttelescopic rod and the centering rod. The surface, connected with the second telescopic rod, of the positioning plate comprises a positioning line. The positioning line is parallel to the axis of thecentering rod. According to the positioning tool, positioning of the eccentric boss can be completed in the manner of regulating the length of the telescopic rods and rotating the positioning tool, and the machining difficulty is lowered.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing of gas turbine products, in particular to a positioning tool for an eccentric boss of a casing of a gas turbine. Background technique [0002] A gas turbine is an internal combustion power machine that uses continuous flowing gas as the working medium to drive the impeller to rotate at high speed, and converts the energy of the fuel into useful work. It is a rotary impeller heat engine. The gas turbine case is a cylindrical casing for installing the impeller on the gas turbine, and the outer surface of the case of the gas turbine has a plurality of eccentric bosses. The eccentric boss on the receiver can be used as a fixing seat for other pipe structures. The eccentric boss can be welded to the receiver after machining. [0003] The eccentric boss is usually processed by a vertical lathe. When clamping the eccentric boss on the workbench of the vertical lathe, in order to ensure...
