Description
Technical field
The present invention relates to a kind of balance toolings of detection blade static-balance state.
Background technology
Propeller needs to do static balancing test after installation is complete, detect each blade of propeller it is low away from, middle-range and greatly away from
Angle under, whether each blade, which keeps, balances, if cannot balance, adjusts the quality of each blade, blade is enable to balance, adjustment
After the quality of blade, it is balanced experiment again, until each blade, which meets balance, to be required.So the static balance examination of blade
It is extremely important test during propeller makes to test.The tooling that the blance test of existing propeller uses is balance shaft, will
It needs the oil pipe for the propeller done experiment to remove, balance shaft is installed to the position of propeller oil pipe, then by balance shaft
It slings to be put on balancing stand and carries out static balancing test.The balance shaft tooling can only realize the blade of propeller under single angle
Experiment, cannot achieve experiment of the blade under multi-angle；If carrying out static balancing test of the blade under multi-angle, it is necessary to will
The balance shaft for being equipped with propeller being placed on balancing stand is removed, each blade of manual setting be same windup-degree after, then will
Balance shaft, which slings to be put on balancing stand, carries out static balancing test, and manual single paddle adjustment angle is time-consuming and laborious, extremely inefficient, and
It is not easy each blade being adjusted to an angle completely.
Invention content
The purpose of the present invention is exactly to solve the above-mentioned problems in the prior art, provides a kind of detection blade static-balance shape
The balance tooling of state does the static balancing test of propeller using the balance tooling, and each paddle on propeller can be realized in tooling
The synchronous adjustment of the windup-degree of leaf, Adjusting accuracy is high, and time saving and energy saving, work efficiency is high.
To achieve the above object, technical solution of the invention is：A kind of balance work of detection blade static-balance state
Dress comprising main shaft, guide tube, displacement nut, retainer nut, thrust bearing, feather key and positioning disk；The front end of main shaft have screw thread and
Sliding slot, displacement nut thread are connected to the front end of main shaft, and guide tube is mounted on by thrust bearing in the outer circle of displacement nut back end,
Displacement nut back end, thrust bearing and guide tube front end are fixed as one by retainer nut；In the outer circle of guide tube front end protrusion one circle with
The raised positioning disk that the pulling sleeve of each blade cam pin of connection in propeller paddle shell matches, is provided on raised positioning disk and pulling sleeve
The location hole that hole above matches, guide tube rear end are fixed with feather key, and feather key is located in the sliding slot of main shaft；Rear-end of spindle interference fills
Equipped with the positioning disk that the end-toothed disc with propeller paddle shell matches, it is provided on positioning disk and matches with the stud on end-toothed disc
Hole.
In use, first integrally unload displacement nut, thrust bearing and guide tube, then by what main shaft penetrated ready to balance paddle is housed
In the paddle shell of leaf component, the stud on the end-toothed disc of propeller paddle shell is through in the hole of positioning disk, symmetrically and evenly with nut
It fixes；Displacement nut, thrust bearing and guide tube are integrally assembled on main shaft again, pay attention to the sliding slot for making feather key enter main shaft
In, by the raised positioning disk on the pulling sleeve and guide tube of each blade cam pin of connection in propeller paddle shell to good, use bolt and nut
Good location hole will be fixed；With spanner rotate displacement nut, displacement nut along main shaft screw thread rotation and move up and down,
Guide tube is pushed to move up and down, guide tube pushing set movement, pulling sleeve drives cam pin rotation, to make each blade of propeller synchronize
Rotation, until required angle；Then main shaft is sling to be put on balancing stand and carries out static balancing test, adjust the matter of blade
Amount reaches the technology requirement of balance；Then displacement nut is adjusted again, makes each blade synchronous rotary to another required angle
Degree carries out static balancing test, adjusts the quality of blade, reaches the technology requirement of balance；Above-mentioned action is repeated, until by propeller
Each blade it is low away from, middle-range and greatly away from angle under all blance tests finish until；According to the above-mentioned blade adjusted
Mass adjust- ment propeller after；It is balanced experiment again, the technology until that can reach balance requires just no longer to adjust blade quality.
The static balancing test that propeller is done using the present invention, can realize the synchronization of the windup-degree of each blade on propeller in tooling
Adjustment, Adjusting accuracy is high, and time saving and energy saving, work efficiency is high.
