Twist straightening device for positioning rib of power generator stator

Abstract

The invention discloses a twist straightening device for a positioning rib of a power generator stator. The twist straightening device comprises a work platform, a power distribution cabinet, an oil tank and a plunger pump. Two die bases are arranged on the left side and the right side of the work platform side by side. The two die bases are internally provided with a movable explorator and a fixed explorator correspondingly. A support is arranged on the rear side of the movable explorator and vertically provided with a hydraulic cylinder. A hydraulic pull rod is vertically arranged at the front end of the hydraulic cylinder. A connecting rod is hinged to the front end of the hydraulic pull rod, and the other end of the connecting rod is fixedly connected with the movable explorator. The movable explorator is driven by the connecting rod to rotate and move around the axis of the movable explorator. The work platform is further provided with a hand-operated hydraulic multi-direction valve. One end of the hand-operated hydraulic multi-direction valve is connected with the plunger pump through a pipeline, and the other end of the hand-operated hydraulic multi-direction valve is connected with the hydraulic cylinder through a pipeline. The twist straightening device is simple and practical in structure and accurate and convenient to operate; and compared with manual straightening of manual work, workpiece clamping is simple, the straightening efficiency is high, time and labor are saved, and the twist straightening device is mainly applied to straightening work of metal workpieces.

Description

technical field [0001] The invention relates to the technical field of twist straightening equipment in machining, in particular to a twist straightening device for stator positioning ribs of a generator. Background technique [0002] There is a positioning rib structure in the stator of the generator. The production of this structure is either directly imported from abroad, or it is processed by machine tools. Most of the production enterprises use machine tool processing to produce by themselves, which will inevitably lead to distortion and deformation of the processed workpiece. Generally, the shape and position tolerance of the workpiece we actually need is 0.1mm / m. In order to ensure this special requirement, the distortion must be The deformed workpiece is straightened. At present, the straightening work is done manually with a bench vise and a wrench. The efficiency is low, the precision is poor, time-consuming and labor-intensive, and it is far from meeting the needs...
