Abstract
The utility model proposes revolution rudder rotating angle measurement apparatus.Concentric pointer and rudder angle dial are installed on rudderpost, the end of rudderpost is connected with angular encoder by device in angular encoder school, angular encoder is connect by data line with angular display unit, the small axis of angular encoder on angular encoder is connected and fixed by the small shaft fixing device of angular encoder outside rudderpost, forbid the small axis rotation of angular encoder, so that the angle stabilization that angular encoder is shown is reliable.Due to accurately converting electric signal for tested revolution rudder rotation angle using angular encoder and intuitively showing, first on the basis of angular encoder, revolution rudder is gone into target angle, keep the state, then the corresponding graduation mark of angle directly is marked on revolution rudder rotation angle dial, so that every graduation mark can accurately reflect the revolution practical rotation angle of rudder, the operability and safety of ship's navigation are improved.It is suitable for being used as revolution rudder rotating angle measurement apparatus.
Description
Technical field
The utility model relates to the measurements in shipbuilding, in particular to be turn round rudder rotation angle dial production.
Background technique
Ship turns round the work of rudder rotation angle measurement, and main purpose is production helm indicator dial, shows on dial
The accuracy for the angle of coming about shown is directly related to the operability and safety of ship's navigation, traditional dial production side
Method, predominantly template method or Geometric figure drawing method.Template method is using the template for having divided angle, according to sample making scale
Disk, and template has unicity, the dial made in this way can not accurately show the angle of coming about of different ships.Geometry
Drawing theoretically can accurately divide the rudder angle dial of single ship, but by the qualification of construction personnel, use
The precise degrees of tool, line width and the influence not of uniform size of sample dotting punch, produced dial still precision is insufficient, can not
It accurately reflects and turns to its angle.
Summary of the invention
In order to improve the production precision of revolution rudder rotation rudder angle dial, the utility model provides revolution rudder rotation angle
Measuring device.The device accurately converts electric signal for tested revolution rudder rotation angle by angular encoder and intuitively shows
It shows and, and directly mark the corresponding graduation mark of angle on revolution rudder rotation angle dial, accurately reflection revolution rudder is practical
Angle is rotated, the operability and safety of ship's navigation are improved, solves the technology of revolution rudder rotation rudder angle dial production precision
Problem.
The utility model technical scheme applied to solve the technical problem is:
Concentric pointer and rudder angle dial are installed on rudderpost, the end of rudderpost in angular encoder school by filling
It sets and is connected with angular encoder, angular encoder is connect by data line with angular display unit, and the angle on angular encoder is compiled
The code small axis of device is connected and fixed by the small shaft fixing device of angular encoder outside rudderpost, forbids the small axis rotation of angular encoder,
So that the angle stabilization that angular encoder is shown is reliable.
Good effect, since the utility model is accurately converted tested revolution rudder rotation angle to using angular encoder
Electric signal is simultaneously intuitively shown, first on the basis of angular encoder, revolution rudder is gone to target angle, keeps the shape
Then state directly marks the corresponding graduation mark of angle on revolution rudder rotation angle dial, so that every graduation mark can be accurate
Reflection turn round the practical rotation angle of rudder, improve the operability and safety of ship's navigation.It is suitable for as revolution rudder rotation angle
Measuring device uses.
Detailed description of the invention
Fig. 1 is utility model diagram；
Fig. 2 is I partial side view of the utility model；
Fig. 3 is II partial side view of the utility model.
In figure, 1. rudderposts, 2. angular encoders, the small axis of 2.1. angular encoder, tooling in 3. angular encoder schools, 4. jiaos
Spend the small shaft fixing device of encoder, 5. angular display units, 6. pointers, 7. rudder angle dials.
Specific embodiment
According to the figure, concentric pointer 6 and rudder angle dial 7 are installed on rudderpost 1, the end of rudderpost passes through angle
Device 3 is connected with angular encoder 2 in encoder school, and angular encoder is connect by data line with angular display unit 5, and angle is compiled
The small axis 2.1 of angular encoder on code device is connected and fixed by the small shaft fixing device 4 of angular encoder outside rudderpost, forbids angle
The small axis rotation of encoder is spent, so that the angle stabilization that angular encoder is shown is reliable.
The course of work of the utility model:
1, device is installed: angular encoder being fixed in angular encoder school in tooling, rudderpost is mounted as a whole on
One end；By adjusting device in angular encoder school, keep angular encoder coaxial with rudderpost.By data line by angular encoder
It is connect with angular display unit, the small axis of angular encoder is connect with the small shaft fixing device of angular encoder, prevents small axis from rotating.It adjusts
Whole pointer and rudder angle dial relative position, to mark scribe line position.
2, angle measurement: rotation rudderpost first makes pointer be directed toward the center of rudder angle dial, marks in the position
Note, as 0 ° of rudder angle line.Angular encoder is zeroed at this time, angular display unit angles of display is 0 °, is to rotate 15 ° of angles of angle
Example, rotation rudderpost are 15 ° to angle shown by rudder angles display is turned round, and rotation and fixed rudderpost are stopped, at this time in pointer
It is marked on corresponding rudder angle dial position and delineates 15 ° of graduation marks.According to said method delineate other angle index lines.
3, examine measurement: the rudder angle dial for completing delineation to angular encoder is tested.It is to examine 15 °~30 °
Example: rotation rudderpost, adjustment pointer are directed toward 15 ° of relative positions on rudder angle dial, angular encoder are zeroed, and angular display unit is aobvious
The angle shown is 0 °, continues to rotate rudderpost, and when 16 ° of pointer direction, 1 ° should be shown on angular display unit；And so on, such as rudderpost
The angle for continuing rotation is consistent with angle shown by angular display unit, and as rudder angle scale plate production is accurate, angle measurement work
It completes, otherwise should re-start angle measurement work.
Claims (1)
1. turning round rudder rotating angle measurement apparatus, concentric pointer (6) and rudder angle dial (7) are installed on rudderpost (1),
It is characterized in that: the end of rudderpost is connected with angular encoder (2) by device (3) in angular encoder school, angular encoder is logical
It crosses data line to connect with angular display unit (5), the small axis of the angular encoder on angular encoder (2.1) passes through the angle outside rudderpost
