Problems solved by technology

[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 up

Embodiment Construction

[0026] In order to deepen the understanding of the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, which are only used to explain the present invention and do not limit the protection scope of the present invention.

[0027] Such as figure 1 As shown, the present invention is a special structure of a large pipe socket groove processing technology, the processing technology includes the following steps:

[0028] (1) Workpiece fixation: Install two V-shaped seats on the drilling machine working platform, and firmly connect the V-shaped seats and the drilling machine working platform with bolts, put the header part on the V-shaped seat, and place the pipe row part on the saddle;

[0029] (2) Adjust the level of the workpiece: Install a threaded lifting frame at the end of the pipe row away from the header, use the lifting frame to change the height of the pipe row, and use a level t...

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.
