Abstract

The utility model discloses a blade installation angle detection tool. The bottom portion of a propeller installation seat is fixed on one end of a workbench in a height-adjustable mode. A pedestal of a reticle plate is detachably fixed on the other end of the workbench. A templet installation groove and an arc installing hole are arranged in the reticle plate. A templet is matched with the templet installation groove in the reticle plate. More than two fixing holes are arranged in positions, matched with the arc installing hole of the reticle plate, of the templet. A groove is arranged in the upper end of the templet, and the groove is matched with a cross-section-shaped working surface of some position of one end, which is far from a propeller hub, of a detected blade. A scratch line is in a center radius of the templet. The templet is attached to the templet installation groove of the reticle plate, and the fixing holes in the templet are fixed together with the arc installing hole in the reticle plate through screw bolts. A cover plate and the upper end of the propeller installation seat are respectively provided with installing holes which can be fixed together. The blade installation angle detection tool is convenient to transport and carry and can carry out blade installation angle measurement at any time. The detection precision is high, the working efficiency is high, and the measurement cost is low.

Description

Blades installation angle testing tool
Technical field
The utility model relates to a kind of testing tool of blades installation angle.
Background technology
Blade is according to having certain at an angle to be arranged on blade propeller hub with its Plane of rotation, after installation, need to detect blades installation angle and whether meet designing requirement, if met the requirements, the installation qualification of blade as undesirable, is recorded error on detecting instrument, then from new installation blade, until qualified.Existing detection method need to realize by instruments such as measuring table, bevel protractor, model, screw propeller mount pads, and measuring table is fixed, and cannot move.In actual use, a lot of Subscriber Units do not have measuring table, even if there is measuring table, much, not by metering test, use it to detect, the bad assurance of measuring accuracy yet.If Subscriber Unit does not have corresponding technical conditions, just cannot accurately regulate wing setting angle, can only return that factory installs, the angle of adjusting, blade detects.If all blade Dou Yaofan factory measures, cause very large difficulty to blade angle testing.
Utility model content
The purpose of this utility model solves the above-mentioned problems in the prior art exactly, and a kind of blades installation angle testing tool is provided, and this testing tool meets request for utilization, and accuracy in detection is high, simple to operate, and work efficiency is high, can move, and easy to carry.
For achieving the above object, technical solution of the present utility model is: a kind of testing tool of blades installation angle, and it comprises screw propeller mount pad, cover plate, semi-circular model and reticle that worktable, top and propeller hub endoporus match; The one end that is fixed on worktable screw propeller mount pad bottom adjustment height, the base of the reticle with angle value scale is removably fixed on the other end of worktable, has mounting groove and the arc mounting hole of model in reticle; Model mounting groove in model and reticle matches, the position that arc mounting hole in itself and reticle matches has plural fixed orifice, there is the groove matching away from the workplace end of the cross sectional shape in somewhere, propeller hub one end with tested blade its upper end, in its center radius, has groove; Model is attached in the model mounting groove in reticle, and by bolt, the arc mounting hole in the fixed orifice on it and reticle is fixed together, and when the groove on it overlaps with 0 ° of scale in reticle, its anglec of rotation is 0 °; Cover plate and screw propeller mount pad upper surface have the mounting hole that can be fixed together.
The structure that is fixed on one end of worktable is screw propeller mount pad described above bottom adjustment height: screw propeller mount pad bottom is a bolt, on this end of worktable, have mounting hole, the bolt of screw propeller mount pad bottom is through in mounting hole, on the bolt of worktable lower end, be fixed with lower nut, on the bolt of upper end, be fixed with upper locking nut.Regulate in advance the position of lower nut on bolt, then upper locking nut is locked on worktable.It is easy to adjust, simple.
When use, the propeller hub of detected screw propeller is enclosed within on screw propeller mount pad, and is fixed by cover plate crimping, the workplace of the blade other end is overlapped in the groove of model, if the height of screw propeller mount pad is improper, regulate its height, to adapt to the height of model; Unclamp the bolt of fixing model and scaleplate, rotation model, make blade be pasted in the groove of model interior after, then fix bolt; Read the angle that model groove departs from 0 ° of scale of reticle, just can obtain the angle of blades installation on propeller hub, if this angle is consistent with the setting angle of designing requirement, illustrate that blades installation is qualified, if inconsistent, calculate error, then raise completeblade at blades installation equipment, make its setting angle qualified.Worktable of the present utility model, screw propeller mount pad, cover plate, model and reticle can move, and transportation, easy to carry, can carry out the measurement of blades installation angle whenever and wherever possible, measure without Zai Fan factory, and it is easy to use, and work efficiency is high; The adjustable height being arranged on worktable of screw propeller mount pad, to regulate the setting height(from bottom) of propeller hub, makes propeller hub adapt to model height, like this, a screw propeller mount pad just can adapt to the installation of the similar propeller hub of differing heights, saves and measures cost, reduces storage space; Worktable is standard operation platform after tested, so its accuracy in detection is high.
