Large tube base groove machining process with special structure

Abstract

The invention relates to a large tube base groove machining process with a special structure. The machining process includes the steps: (1) fixing a workpiece: mounting two V-shaped seats on a drilling machine working platform and placing part of a header on the V-shaped seats; (2) adjusting the workpiece to be horizontal: measuring the end face of a tube base by the aid of a level and adjusting the machined end face to be horizontal; (3) positioning a cutter head; (4) leveling the end face of the tube base; (5) machining an inner bore; (6) machining a 7-degree position of a groove; (7) machining a 30-degree position of the groove; (8) finishing machining, and measuring whether size detection meets requirements through a vernier caliper. The large tube base groove is machined, the special cutter head is designed, the circle center of the workpiece is positioned by the aid of a positioning pin circle drawing method, the position of a cutter is adjusted by the aid of a gasket, the groove is machined on the same end face for a plurality of times, a device is free of overload, a positioning ring is used for positioning in machining, rough machining is firstly performed, fine machining is secondly performed, and efficiency is ensured.

Description

technical field [0001] The invention relates to a processing technology of a bevel, in particular to a processing technology of a groove of a large pipe seat with a special structure. Background technique [0002] The bevel processing of the large pipe seat with special structure cannot be processed by a conventional beveling machine. If it is to be processed, the pipe row can be placed vertically, but it is difficult to position the pipe row in this way, and the cutter head interferes with the workpiece, which is not feasible , and the pipe seat is a blind hole, the inner diameter positioning equipment will interfere, the positioning is difficult, the external location is affected by the welding seam, and the processing accuracy is difficult to control, so the processing of the large pipe seat groove is considered from the perspective of control positioning and convenient processing observation and measurement. It should be that the nozzle of the tube seat needs to face...
