Description
Technical field
The present invention relates to a kind of marine distance adjusting propeller hub body static equilibrium metering system.
Background technology
Marine distance adjusting propeller hub body profile is approximate dolioform round platform, there is multiple (being generally 4 ~ 5 places) uniform installation counterbore in cydariform face, corresponding regular polygon inner chamber, propeller hub body large end face is uncovered, small end face is semiclosed, generally being arranged on the afterbody of ship, having multiple blade coupled, is the critical component that blade is connected with oar axle.The duty of propeller hub body is high speed rotary motion, for reducing unbalanced moments when rotating, must carry out static equilibrium measurement to propeller hub body, controls unbalanced moments and reaches designing requirement.Propeller hub body static equilibrium deviation requirement is high, and testing result comparatively relies on checkout equipment, the precision of frock and sensitivity.Current propeller hub body static equilibrium detection mode is that propeller hub body is worn axle and carried out on drum-type static balancing frame, and which has more difficult point:
1, frock prepares difficulty greatly, need make the auxiliary moulds such as supporting drum-type static balancing frame, balancing shaft, large end web joint and large small end tapered sleeve for often kind of propeller hub system.
2, frock precision, sensitivity are poor, and it is more that a whole set of frock comprises part, and the factors such as accumulation gap error, bias affect measurement result accuracy.
3, process efficiency is low, and after frock is installed, propeller hub body upper and lower end face is closed, when static equilibrium detects defective, grinding tool is not easily worked into inner chamber position, just can carry out reconditioning after frock need being dismantled, reinstall frock again and detect static equilibrium, repeatedly repeatable operation just can reach requirement.
4, duplicate measurements deviation is large, and because of factors such as frock accumulation eccentric errors, when propeller hub body is again installed and detected static equilibrium, measured deviation changes greatly, and causes production operation repeatable operation and checks and accepts difficulty.
5, propeller hub body is intensely processed products, repeatedly removes and installs and causes damaged products.
In sum, for the propeller hub body static equilibrium requirement day by day improved, novel metering system need be found and meet the demands.
Summary of the invention
The object of the invention is for above-mentioned present situation, aim to provide and a kind of measure that efficiency is fast, measurement result marine distance adjusting propeller hub body static equilibrium accurately metering system.
The implementation of the object of the invention is, marine distance adjusting propeller hub body static equilibrium metering system, and concrete steps are as follows:
1) make adjustable support roller, adjustable support roller is made up of two groups of rotational lead screws, roller, two slide carriages and pedestal; Roller is inlayed and is fixed on slide carriage, and slide carriage is fixed by bolts on pedestal, and rotational lead screw runs through pedestal and slide carriage;
2) make measurement bay, the automatic positioning mechanism of hemispherical groove structure is arranged at measurement bay bottom, and on measurement bay top along center line symmetrical machining two row bolt hole, two groups of adjustable support rollers are fixed by bolts on measurement bay;
Measuring table is fixed with feeler, hydraulicefficiency elevation structure, sensor and hydraulicefficiency elevation structure top are furnished with the bulb coordinated with automatic positioning mechanism;
3) measuring equipment is started, measurement bay is fallen, sensor and hydraulicefficiency elevation structure top bulb contact automatic positioning mechanism, adopt bikini to survey gravity model appoach and measure testee center of gravity, and by the moment numerical value of formula conversion display directly perceived testee relative to a part;
4) propeller hub body level is sling, is placed horizontally on the roller of adjustable support roller, propeller hub body two ends place cylinder contact roller, by rotational lead screw adjustment roller centering centering, realize the quick position of propeller hub body:
5) again measurement bay is fallen, the hemispherical groove of automatic positioning mechanism contacts with feeler, measures propeller hub body in the weight of mark position, barycentric coordinates and moment deviation, rotates propeller hub body, gather measurement data at mark position respectively, calculate and contrast propeller hub moment of volume deviation difference; To moment deviation larger portion position, directly reconditioning propeller hub intracoelomic cavity on measuring instrument, until product moment deviation meets the requirements.
The present invention efficiently solves during the static equilibrium of propeller hub body is measured the difficulty run into, and can achieve the static equilibrium of propeller hub body quickly and easily, measurement efficiency is fast, measurement result is accurate.
