Description
Technical field
The utility model relates to adjustable pitch propeller field of measuring technique, particularly a kind of contactless adjustable pitch propeller measurement mechanism.
Background technology
In the manufacturing process of screw propeller, measure the instrument mainly thread pitch gauge of adjustable pitch propeller, the geometric parameter such as airscrew pitch, radius can be measured by thread pitch gauge.Thread pitch gauge volume is comparatively large, and each measurement products all needs the cooperation about 3 people, and wherein a people must lift by crane thread pitch gauge, two people coordinate installation thread pitch gauge, and coordinate the carrying out of follow-up whole measuring process.Carrying out in driving lifting and installation process, thread pitch gauge be also easier to cause rock, landing, even to damage, and the cooperation of two people loss cost of labor too in measuring process.Measure and terminate inspection and the primary Calculation that rear survey crew also needs to carry out measurement data, whole process is more loaded down with trivial details, and efficiency is lower.
Wait due to above-mentioned the realistic problem existed, someone adjusts equipment at begin one's study contactless measurement and school, can complete the surveying work to screw propeller by the cooperation of shooting, computer for analysis and measurement mechanism, but not yet specific in some products.
Summary of the invention
The purpose of this utility model is exactly to overcome the difficult problems such as measuring equipment volume in existing measuring technique is large, heavy, operation easier are high, propose a kind of assembly-non-contact measurement apparatus of contactless screw propeller measuring equipment, make the realization of non-contact type measuring device become possibility.
A kind of contactless adjustable pitch propeller measurement mechanism, is characterized in that described device comprises LED group, the body of a gun and rifle head;
The described body of a gun is made up of two symmetrical trough-shaped housings, after two housing symmetry dresses close, middlely forms hollow chamber; Two housing the same sides are provided with symmetrical some half round cut, form some circular lamp holes after housing dress closes; Housing two ends are respectively equipped with a semicircular indentations, and after dress closes, rear and front end forms a circular string holes and a circular rifle head mounting hole respectively;
The described body of a gun is divided into handle and barral of a gun, and described handle is the bending shaft-like of center protrusion; Barral of a gun is " Z " shape structure, and both are integral type structure; Handle and barral of a gun are respectively equipped with a power switch, and two power switches are ganged switch;
The nearly mounting hole position of described barral of a gun head, is provided with semi-cylindrical switch shaft; Switch shaft runs through the body of a gun, and one end is provided with swingle, and the other end and the body of a gun are rotatably connected fixing;
Described rifle head is taper, comprises conehead and cone, and described conehead is threadedly mounted on centrum one end, and conehead top is provided with plastics contact; The centrum other end is provided with half-terete cone tail, and cone tail is provided with semi-circular recesses; Rifle head is connected together fixing by cone tail and switch shaft;
Described LED group comprises some LED, and correspondence is installed in the lamp hole on the body of a gun, and light source is external;
Described LED group, power switch and rifle head lamp pass through connection.
Beneficial effect:
1. the utility model proposes a kind of novel screw propeller measurement mechanism, meet the measurement demand of non-contact measurement apparatus, and overcome the difficult problem that conventional measurement devices volume is large, weight is large, operation easier is large.
2. the measurement mechanism structure that the utility model proposes is simple, and materials are slim and graceful, very easy to use.By assembling ganged switch on body of a gun handle and barral of a gun, survey crew Convenient switch LED group when different measuring posture can be met, making to measure equipment and using as snug as a bug in a rug.
3. the measurement mechanism that the utility model proposes, rifle head adopts the mode be movably fastened to be connected with the body of a gun, only needs to rotate swingle during installing/dismounting, just can remove lower rifle head easily and replace, greatly having saved the maintenance period of device, and being easy to deposit and maintain.
