Abstract

The invention discloses a rotary welding frame structure for a spindle and flanges of a water turbine. The rotary welding frame structure comprises a base and a support arranged on the base, a weldingseat is arranged on a top portion of the support, a spindle fixing structure is arranged on the welding seat, a rotary cavity is formed in the base, a rotary motor is fixed on the base, a driving gear is fixed on a spindle of the rotary motor, a transmission gear is fixed on the support, a recessed area is formed in a middle portion of the welding base, the spindle fixing structure comprises a fixed seat, a U-shaped holding groove is fixedly formed in the fixed seat, locking screws are arranged on a side portion of the fixed seat, a semicircular overturning block is fixed in the middle of a bottom face of the fixed seat, toothed grooves are fixed in a circular edge of the semicircular overturning block, an overturning motor is fixed on the fixed seat, and a control gear is fixed on a spindle of the overturning motor. The rotary welding frame structure is reasonable in structure arrangement, convenient and fast to operate, beneficial to guaranteeing of welding quality and welding precision, stable and reliable to use and high in applicability and practicability.

Description

technical field [0001] The invention belongs to the technical field of water turbine manufacturing equipment, and in particular relates to a rotary welding frame structure used for a water wheel main shaft and a flange. Background technique [0002] A water turbine is a power machine that converts the energy of water flow into rotational mechanical energy. It guides the water in the upstream reservoir to the water turbine through the diversion pipe, drives the water turbine to rotate and discharges it downstream through the tail water pipe, and realizes the generator through the rotation of the water turbine. Power generation, but because the volume of the water turbine is very large, the volume of the internal parts of the water turbine is also very large, and the main shaft of the water turbine is an important part of the water turbine, and its two ends need welding flanges. The operation of welding the flanges at both ends is very cumbersome. At the same time, the main sh...

[0002] A water turbine is a power machine that converts the energy of water flow into rotational mechanical energy. It guides the water in the upstream reservoir to the water turbine through the diversion pipe, drives the water turbine to rotate and discharges it downstream through the tail water pipe, and realizes the generator through the rotation of the water turbine. Power generation, but because the volume of the water turbine is very large, the volume of the internal parts of the water turbine is also very large, and the main shaft of the water turbine is an important part of the water turbine, and its two ends need welding flanges. The operation of welding the flanges at both ends is very cumbersome. At the same time, the main shaft of the turbine cannot be rotated during welding, which will also cause a part of the flange to be welded, which will affect the quality of the welding. It also affects the efficiency of welding, so the applicability and practicality are limited
