Problems solved by technology
[0003] Before the fine boring of the shafting boring process in the process of shipbuilding and shafting installation, it is necessary to draw a boring circle on the cross-section of the casting and forging for further fine boring operations. Traditional operations often use hand-held compasses to draw circles. The operation Inconvenient, poor precision, high requirements for the operator's operating level and construction experience, which can easily lead to unstable or poor quality of the circle drawing accuracy before the shaft boring

Abstract
The invention relates to the field of ship manufacturing tools, in particular to a fixed type boring circle drawing device. The fixed type boring circle drawing device comprises a vertically-arrangedfirst connecting arm and a base used for supporting the first connecting arm, and further comprises a second connecting arm perpendicular to the first connecting arm, and the height of the second connecting arm is adjustable. The fixed type boring circle drawing device further comprises a third connecting arm and a circle drawing needle, one end of the third connecting arm is rotationally connected with the second connecting arm, and the other end of the third connecting arm is rotationally connected with the circle drawing needle. The fixed type boring circle drawing device is simple in structure, convenient to use and easy to operate, accurate circle drawing for cast and forged part section boring can be achieved, and the boring quality is guaranteed; and due to the arrangement of the base of the fixed type boring circle drawing device, the base can easily coincide with a boring cutter rod, adsorption and fixation are conducted, the length of the fixed type boring circle drawing device can be adjusted so that the fixed type boring circle drawing device can be suitable for cast and forged parts different in size, and practicability is high.
Description
technical field [0001] The invention relates to the field of shipbuilding, in particular to a fixed boring and circle drawing device. Background technique [0002] Boring is the further processing of forging and casting rough holes. In the shafting installation stage of berth in shipbuilding, shafting boring, as a key process, plays a very critical role in the quality of shafting installation. Boring can enlarge the aperture, improve precision, reduce surface roughness, and can better correct the deviation of the original hole axis. Boring can be divided into rough boring, semi-fine boring and fine boring. The dimensional accuracy of fine boring can reach IT8~IT7, and the surface roughness Ra value is 1.6~0.8μm. Boring is divided into general boring and deep hole boring. General boring can be done on ordinary lathes, and the boring tool can be fixed on the tailstock of the lathe or on a small tool holder. Deep hole boring requires a special deep hole drilling and boring m...
