Boring technology for rudder blade

Abstract

The invention relates to a boring technology for a rudder blade. A rudder blade hole comprises a conical hole and a short hole which coaxially communicate with each other from outside to inside. The technology comprises the following steps: (1), after the rudder blade is manufactured, the rudder blade is adjusted to be horizontal; the four sides of the rudder blade are well supported by wood blocks; the periphery of the rudder blade and the centers of the two holes are regulated by using a steel ruler and a laser theodolite; (2), according to a central line of the rudder blade provided in the first step, a steel wire is drawn between a rudder rod steel casting large end and the center of a bottom sealing plate and is centered; (3), a boring rod is inserted; (4), after the boring rod is calibrated, tool setting and hole boring are performed; (5), after fine boring is finished, a boring machine is demounted, and supports are cut; polishing is performed; the surface of the oil hole is smoothed; the dimensions of the bored hole are reported to an inspection department; a steel wire is drawn, and the hole concentricity is rechecked based on rudder pintle and rudder rod support base large end part technological reference screws; and recording is performed; an inspection form is filled in; steel casting flaw detection is performed; and grease is smeared in the hole, so that rusting is avoided.

Description

technical field [0001] The invention relates to a ship building process, in particular to a rudder blade boring process. Background technique [0002] The performance of ship rudder blade directly affects the driving of the ship, but due to its large size, it is difficult to guarantee the accuracy of the connection holes on it, and the processing cycle is long, which affects the ship construction cycle. Contents of the invention [0003] The invention provides a rudder blade boring process capable of ensuring machining accuracy and taking into account the machining cycle. [0004] The technical solution adopted in the present invention is: a rudder blade boring process, the rudder blade hole includes a conical hole and a short hole connected coaxially from the outside to the inside, and the process steps are: [0005] (1) After the rudder blade is finished, adjust the level of the rudder blade, pad the four sides with pier, use a steel ruler and laser theodolite to adjust...
