Abstract
The invention discloses a balance tool for detecting a static balance state of a blade. The front end of a main shaft is provided with threads and a sliding chute; a variable pitch nut is in threaded connection with the front end of the main shaft; a guide drum is arranged on the outer circle at the rear end of the variable pitch nut through a thrust bearing; the rear end of the variable pitch nut, the thrust bearing and the front end of the guide drum are integrally fixed by a stop nut; a circle of convex positioning disc which is matched with a poking sleeve connected with each blade eccentric pin in a propeller shell protrudes on the outer circle at the front end of the guide drum and is provided with a positioning hole which is matched with a hole in the poking sleeve; the rear end of the guide drum is fixedly provided with a sliding key; the sliding key is positioned in the sliding chute of the main shaft; the rear end of the main shaft is in interference fit with the positioning disc which is matched with an end-toothed disc of the propeller shell; the positioning disc is provided with a hole which is matched with a stud on the end-toothed disc. By conducting a static balance test of the propeller with the tool, the tool can realize synchronous adjustment of a torsion angle of each blade on the propeller per se, the adjustment is high in accuracy, time and labor are saved, and the working efficiency is high.
Description
Technical field
The present invention relates to a kind of balance tooling detecting blade static-balance state.
Background technology
Need to do static balancing test after screw propeller installation, detect each blade of screw propeller under the angle of low distance, middle distance and large distance, whether each blade keeps balance, if can not balance, regulate the quality of each blade, blade is balanced, after the quality of adjustment blade, again carry out balance test, until each blade meets balance requirement.So the static balancing test of blade is extremely important test in screw propeller manufacturing process.The frock that the balance test of existing screw propeller uses is balancing shaft, by needing the oil pipe of the screw propeller of doing experiment to take off, balancing shaft being installed to the position of screw propeller oil pipe, then being sling by balancing shaft to be put on balancing stand and carry out static balancing test.This balancing shaft frock can only realize the test of blade under single angle of screw propeller, cannot realize the test of blade under multi-angle; If carry out the static balancing test of blade under multi-angle, the balancing shaft being provided with screw propeller be placed on balancing stand is just needed to take off, the each blade of manual setting is after same windup-degree, again balancing shaft is sling to be put on balancing stand and carry out static balancing test, manual single paddle adjustment angle wastes time and energy, efficiency is extremely low, and not easily each blade is adjusted to an angle completely.
Summary of the invention
Object of the present invention solves the above-mentioned problems in the prior art exactly, a kind of balance tooling detecting blade static-balance state is provided, this balance tooling is used to do the static balancing test of screw propeller, frock can realize the synchronous adjustment of the windup-degree of each blade on screw propeller, Adjusting accuracy is high, time saving and energy saving, work efficiency is high.
For achieving the above object, technical solution of the present invention is: a kind of balance tooling detecting blade static-balance state, and it comprises main shaft, guide, displacement nut, stop nut, thrust bearing, feather key and positioning disk; There are screw thread and chute in the front end of main shaft, and displacement nut thread is connected to the front end of main shaft, and guide is arranged on the cylindrical of displacement nut back end by thrust bearing, and displacement nut back end, thrust bearing and guide front end are fixed as one by stop nut; Guide front end cylindrical projection one encloses the protruding positioning disk matched with the pulling sleeve of the connection each blade eccentric pin in screw propeller oar shell, protruding positioning disk has with pulling sleeve above the pilot hole that matches of hole, guide rear end is fixed with feather key, and feather key is positioned at the chute of main shaft; Rear-end of spindle elastic conjunction has the positioning disk matched with the end-toothed disc of screw propeller oar shell, positioning disk has the hole matched with the stud on end-toothed disc.
During use, first displacement nut, thrust bearing and guide entirety are unloaded, then main shaft is penetrated ready to balance be equipped with in the oar shell of paddle components, the stud on the end-toothed disc of screw propeller oar shell is through in the hole of positioning disk, with nut fixing symmetrically and evenly; Again displacement nut, thrust bearing and guide integral installation are fitted on main shaft, note making feather key enter into the chute of main shaft, by the protruding positioning disk on the pulling sleeve of the connection each blade eccentric pin in screw propeller oar shell and guide to good, fix to good pilot hole with bolt and nut; Rotate displacement nut with spanner, displacement nut along main shaft screw thread rotation and move up and down, promote guide and move up and down, guide pushing cover is mobile, and pulling sleeve drives eccentric pin to rotate, thus makes each blade synchronous rotary of screw propeller, until required angle; Then sling by main shaft to be put on balancing stand and carry out static balancing test, the quality of adjustment blade, reaches the technical requirement of balance; And then regulate displacement nut, make each blade synchronous rotary to another required angle, carry out static balancing test, the quality of adjustment blade, reaches the technical requirement of balance; Repeat above-mentioned action, until all balance tests of each blade of screw propeller under the angle of low distance, middle distance and large distance finished; After Mass adjust-ment screw propeller according to the above-mentioned blade adjusted; Carry out balance test again, until the technical requirement that can reach balance just no longer adjusts blade quality.Use the present invention to do the static balancing test of screw propeller, frock can realize the synchronous adjustment of the windup-degree of each blade on screw propeller, and Adjusting accuracy is high, time saving and energy saving, and work efficiency is high.
