Problems solved by technology

[0003] The present invention solves the problem that the jaw clamping force of the existing steam turbine rotor in the process of clamping the rotor by the horizontal lathe will cause indentation and scratches on the finished surface of the rotor. In order to solve the problem of shaft channeling caused by copper gaskets between the copper gaskets and the loosening of copper gaskets, which will cause greater secondary damage to personnel and equipment, an auxiliary clamping device for turning steam turbine rotors on horizontal lathes is proposed.

Abstract

The invention provides an auxiliary clamping device used by a horizontal lathe for turning a steam turbine rotor and relates to the clamping device. The clamping device aims to solve the problems that in the machining process of an existing steam turbine rotor, jaw clamping force causes dents and scratches to a rotor fine machining face when a horizontal lathe clamps a rotor, a copper gasket between a jaw of the horizontal lathe and the fine machining face generates the axial channeling phenomenon, and higher personnel and equipment secondary harm is caused due to loosening of the copper gasket. The auxiliary clamping device comprises a U-shaped plate, a cuboid copper gasket and a plurality of bolts, and the cuboid copper gasket is arranged in an opening of the U-shaped plate. By means of the auxiliary clamping device, the problems that in the machining process of the existing steam turbine rotor, dents and scratches are caused to the fine machining face when the horizontal lathe clamps the rotor, the copper gasket between the jaw of the horizontal lathe and the fine machining face generates the axial channeling phenomenon, and higher personnel and equipment secondary harm is caused due to loosening of the copper gasket are solved, and the auxiliary clamping device is applicable to auxiliary clamping of the steam turbine rotor.

Description

technical field [0001] The invention relates to an auxiliary clamping device for turning a steam turbine rotor by a horizontal lathe. Background technique [0002] The steam turbine rotor generally uses a horizontal lathe during the processing process. The horizontal lathe generally adopts a clamping and supporting method for the rotor, that is, one side clamps the outer circle of the rotor, and the other side is supported by the hydraulic bracket on the shaft of the rotor. On the neck, the claws of the horizontal lathe are clamped at the outer circle of the rotor for finishing during finishing, and the clamping force of the claws will cause indentations and scratches on the finishing surface of the rotor, so it is usually used between the four claws and the finish machining Copper gaskets are added to the outer surface of the rotor to avoid damage to the outer circle of the rotor. However, due to the heavy weight of the rotor, the shaft system will have high sides and low d...
