Processing working table of guide vane shaft hole of inner and outer water distribution rings of turbine

Abstract

The invention discloses a processing working table of a guide vane shaft hole of inner and outer water distribution rings of a turbine, which comprises a base, wherein a tooling surface is installed above the base, the tooling surface and the base are installed in a tilted angle, the center of the tooling surface is equipped with a support seat which is vertical to the tooling surface, the periphery of the tooling surface is equipped with a plurality of roll shaft supports, eccentric roll shafts are installed on the roll shaft supports, the eccentric roll shafts are sleeved with workpiece support roll wheels, the peripheries of the workpiece support roll wheels are equipped with lateral positioning wheels, fixing bolts are installed near the roll shaft supports, pressing plates are installed on the fixing bolts, and the top of the support seat is equipped with a boring bar guide seat. The processing working table is firm in structure and accurate in positioning; the processed workpiece can rotate 360 degrees on a rotary table, so that holes and planes at any angle can be processed, and the processing holes, the processing planes and the workpiece axis are ensured to be deviated into a fixed angle. A boring bar can be used for simultaneously processing the inner ring hole and the outer ring hole of the water distribution ring, so that the coaxiality of taper holes is assured, the processing procedure is simplified, the product quality and the processing efficiency are improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to a rotary table, in particular to a working table for processing shaft holes of guide vane shaft holes of inner and outer water distribution rings of water turbines. Background technique [0002] Water turbine is a kind of hydropower equipment widely used in the world, and its maximum efficiency can reach more than 90%. Its working principle is that water flows through the pressure steel pipe and enters the volute to form a closed circulation. After the guide vane is opened, the water flow enters the runner and then flows out of the runner. During this process, the water flow energy is transmitted to the turbine due to the interaction between the water flow and the runner. , the water turbine starts to rotate to do work, and the water turbine drives the rotor of the generator to rotate. According to the principle of electromagnetic induction, an AC electromotive force is generated in the three-phase stator winding, thereby gener...
