Processing method of eccentric full-revolving steering oar device base

Abstract

The invention relates to a processing method of an eccentric full-revolving steering oar device base. The eccentric full-revolving steering oar device base comprises a round base panel, wherein the base panel is provided with an eccentric round hole and is in an annular shape, the bottom surface of the base panel is provided with an inner tube body and an outer tube body, the axial line of the inner tube body is coincident with the axial line of the eccentric round hole, the axial line of the outer tube body is coincident with the axial line of the peripheral wall of the base panel, and a knee plate is arranged between the inner tube body and the outer tube body. The processing method is characterized by comprising the following steps of 1, a processing step of the base panel, the inner tube body and the outer tube body; 2, a combination positioning step; 3, a whole welding step; and 4, a machining and hole drilling step. Compared with the prior art, the processing method has the following advantages that 1, the utilization rate of materials is improved, and the consumption of welding materials is reduced; 2, the welding deformation is perfectly controlled, and the precision requirement of equipment is met; 3, the node production requirement is met through reducing the manufacturing and processing time; 4, the transportation cost is reduced; 5, the integral manufacturing cost is reduced.

Description

Technical field: [0001] The invention relates to a processing method of a mounting base of marine equipment, in particular to a processing method of a base of an eccentric full-rotation rudder propeller device. Background technique: [0002] With the advent of the marine economy and the demand for energy in various countries, the demand for offshore engineering supply ships has also been increasing year by year in recent years, and the propulsion method has also developed from the traditional tail shaft fairing type to the full-turn type. At present, the full-turn equipment used in high-power offshore engineering ships, especially the base of the eccentric full-turn rudder and propeller device, has the problems of high production cost and difficult control of production accuracy due to reasons such as large size, heavy weight, and inconvenient transportation. . In particular, the high cost of subcontracted production, difficult control of production accuracy, difficult tran...
