Abstract

The invention provides a large ship stern tube casting inner hole machining scribing device. The device is used for drawing large component inner hole machining round lines, datum lines and the like.The device comprises a circle center gauge, adjusting bolts, a center ring, a rotating base, a supporting ring and supporting bolts, a plurality of holes for the supporting bolts and adjusting knobs are formed in a stable ring, and the holes for the supporting bolts and the adjusting knobs are formed in a staggered mode; and a bull's-eye sleeve is arranged in the stable ring, the bull's-eye sleeveis arranged on the outer ring of the rotating base in a sleeving mode, and the circle center gauge is fixed above the rotating base and rotates in a circular track in the bull's-eye sleeve through the rotating base. The device has the beneficial effects of being easy to operate, low in manufacturing cost and capable of being repeatedly used.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding, and in particular relates to a marking device for machining inner holes of large ship stern tube castings. Background technique [0002] Scribing is an important process in mechanical processing. Scribing refers to the operation of accurately drawing the processing boundary on the surface of the workpiece according to the size of the drawing or the object. [0003] Taking the shipbuilding process as an example, in the process of machining the inner hole of the stern tube casting, it is necessary to draw a machining circle line based on the center of the inner hole of the stern tube, so as to finish the inner hole of the casting. Then the common circular line planning cannot meet the needs of this work, and the processing circular line cannot be determined according to the inner hole. Contents of the invention [0004] In order to solve the above problems, the object of the present inventi...
