Abstract

The invention discloses a hydraulic combined supporting system for marine propeller blade processing. The hydraulic combined supporting system comprises a hydraulic power element, a hydraulic controlloop, hydraulic control elements and hydraulic actuating elements. According to the hydraulic combined supporting system disclosed by the invention, a hydraulic combined control system is adopted; inorder to solve the propeller blade supporting problem, a supporting scheme which is relatively low in cost, relatively simple in supporting form and high in control precision is provided; when the size of a propeller is bigger, the quantity of supporting devices can be increased by adding a similar power actuating mechanism d, one-way valves d, stroke switch d, two-position two-way electromagneticreversing valve d and back pressure valve d in a hydraulic system; when the size of the propeller is relatively small, the quantity of supporting systems can be reduced as long as the two-position two-way electromagnetic reversing valve d is prevented from being externally connected with a power source; the operation is simple; and the hydraulic combined supporting system for marine propeller blade processing and the supporting devices are flexible to use.

Description

technical field

[0001] The invention relates to the field of marine propeller manufacturing and the field of propeller processing supported by a hydraulic control system, in particular to a combined support system and device for processing large-scale marine propeller blades used on heavy machine tools. Background technique

[0002] The marine propeller is the core component of the ship's power system, and its processing quality directly affects the performance of the ship's propulsion system. During the machining process, the propeller blades will be greatly deformed under the action of cutting force, resulting in insufficient cutting depth, resulting in large errors in the shape, size and position of the processed parts. Therefore, proper support must be taken for the blades System, to enhance the stiffness of the propeller blades, to reduce the errors in the shape, size and position of the parts caused by insufficient support, and improve the machining accuracy of the mar...
