Abstract

The invention discloses a device for scribing and trepanning a cambered workpiece. The device comprises a base, a support, a lifting mechanism along the support, a big beam, a swing mechanism, a circle center locating mechanism, a bore diameter calibration mechanism, a scribing mechanism capable of lifting and moving left and right, and a trepanning mechanism capable of lifting and moving left and right. By adopting the device, the problems of big error, low efficiency and the like of manual scribing are solved, scribing and trepanning can be completed on the same device, and the overall production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of hole-drilling devices, in particular to a device for scribing holes on a workpiece with a curved surface. Background technique [0002] Workpieces with curved surfaces, such as pipes, heads, and cylinders, are commonly used components in pressure vessels. During production and processing, it is often necessary to open some holes with required diameters on pipes, heads, and cylinders so that Welded joints, pressure gauges, air outlets, etc. The position accuracy of the opening directly affects the welding quality. At present, manual scribing is generally used for scribing and opening of workpieces with curved surfaces such as pipes, heads, and cylinders. The production efficiency is low and the precision is not high, which brings a lot of trouble to the subsequent assembly and welding, and even some unnecessary of rework. At present, in the industrial production of the opening of pipes, heads and cylind...
