The invention discloses a bus shell flange hole coaxiality shape correction fixture and a correction method. The shape correction fixture comprises a base plate and a vertical plate fixedly connected onto the base plate; the vertical plate is provided with a connection plate the axis of which is arranged horizontally; the connection plate can rotate around the self axis; the connection plate is fixedly connected with a flange plate which is provided with a plurality of installation holes positioned on the same periphery; the end faces of the flange plate deviated from the connection plate are provided with two correction blocks; workpieces the shape of which to be corrected are arranged on two shape correction fixtures which are arranged relatively; the lower parts of the two correction blocks are respectively provided with a jack; one jack is pressed so as to lead the flange plate to rotate; the flange plate is blocked to rotate in a reverse direction by the other jack; the two flanges of the bus shell generate relative rotation; the welding seam on the bus shell is heated; the alloy strength is lowered; and the coaxiality correction is finished. According to the shape correction fixture provided by the invention, the coaxiality of the flange hole of the bus shell is corrected to be within Phi 1 mm; and the shape correction fixture has a novel structure, is special and simple, and has low manufacturing cost and high qualification rate.
Description
technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a tool for correcting the shape, in particular to a tool for correcting the coaxiality of the flange hole of a busbar shell, and the invention also relates to a tool for correcting the shape of the busbar shell by using the tool for correcting the shape The method of the coaxiality of the flange hole. Background technique [0002] The 800KVGIS busbar shell is made of a machined aluminum-magnesium alloy barrel and two machined cast aluminum-silicon alloy flanges and welded. After welding, the end face size and hole size of the flanges of the two castings are no longer machined. However, after welding, the coaxiality of the inner holes of the flanges of the two castings does not meet the requirement of Φ1mm, and the current calibration tool cannot ensure the flatness and parallelism of the flanges. Axis calibration is qualified. Contents of the invention [0003] I...
