Semifocal chord pipe groove processing method and device

Abstract

The invention discloses a semifocal chord pipe groove processing method and device used for processing of a semifocal chord pipe groove or a curved surface groove of a self-elevating drilling platform; the device comprises a planer milling machine, a semifocal chord pipe processing fixture and a semifocal chord pipe processing cutter, the semifocal chord pipe processing fixture is installed on a working table of the planer milling machine, the work table is provided with a clamping groove for positioning the semifocal chord pipe processing fixture, and the semifocal chord pipe processing cutter comprises at least two sets of molding tools which are respectively used for processing of groove planes of the semifocal chord pipe groove and outer-side rounded slots. The method includes the following steps: positioning and clamping, to be more specific, at least two to-be-processed semifocal chord pipes are positioned and clamped in the semifocal chord pipe processing fixture; milling, to be more specific, the molding tools are used for respectively processing the groove planes on the outer side of the semifocal chord pipes and the outer-side rounded slots; exchange processing, to be more specific, the two semifocal chord pipes are exchanged, unprocessed parts in the semifocal chord pipes are processed by the above steps of positioning and clamping and milling; and material feeding, inspection and application for inspection.

Description

technical field [0001] The invention relates to a machining method and equipment, in particular to a half-chord beveling method and equipment for jack-up drilling platform half-chord beveling or similar curved surface beveling. Background technique [0002] The half-chord of the jack-up drilling platform is made of high-strength steel, and the expanded size of a single half-chord is more than 8 meters * 0.4 meters. The shape of the half chord is pressed through a large hydraulic mold. The inner and outer bevels and circular grooves at both ends of the half-chord are usually milled by edge milling machine equipment. Because the parts are super large and semi-circular, the clamping stability on the machine tool is poor when processing the ends, and the two clampings can only Processing one piece, the production cost is high and the efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a half-chord be...
