Machining process for rotating vane type hydraulic steering engine

Abstract

The invention discloses a machining process for a rotating vane type hydraulic steering engine. The machining process comprises the following machining procedures: machining a rotor, a cylinder and a fixed blade, assembling the cylinder and the fixed blade, machining the rotor body of the rotating vane type hydraulic steering engine and machining a sealing groove of the fixed blade, wherein in the rotor body machining procedure, a moveable blade and a substrate are separately machined; in the cylinder machining procedure, the casted and molded blank is subjected to coarse turning, precise turning, pneumatic grinding, polishing with sand bags, round angle trimming and oil hole machining on a numerical control vertical lathe; in the machining procedure of the fixed blade of the rotating vane type hydraulic steering engine and the assembling procedure of the fixed blade and the cylinder, the casted and molded blank is subjected to coarse turning, ageing, semi-precise turning, linear cutting, cover plate mounting hole boring, clamping, boring first mounting threaded holes of the cylinder, fixing cylinder and the fixed blade, machining pin holes and threaded holes for assembling the cylinder and the fixed blade, clamping, hydraulic valve mounting hole drilling, sealing groove boring and milling, fixing the cylinder and the fixed blade, precise turning of inner holes of the assembled fixed blade, threaded holes and sealing groove machining, and facing-up with the cylinder cover, so as to finish machining.

Description

technical field [0001] The invention relates to a processing technology of ship equipment, in particular to a processing technology of a rotary vane hydraulic steering gear. Background technique [0002] Under the macro-strategy of the country's development and construction of marine resources, there are more and more domestic design and production units of ships and marine engineering equipment, and the overall level is getting higher and higher. In the process of the overall development of my country's industry strength, ship-related products play a fundamental and core role. As one of the key equipment of the ship, the steering gear plays an irreplaceable role. It can be predicted that for quite a long time, the steering gear is still the most important ship steering control device. [0003] At present, more and more ships use reciprocating steering gear as the rudder steering device. The technology of reciprocating steering gear is mature, but its disadvantages of lar...
