Description
Technical field
The utility model is related to robot fields, are specially a kind of steering engine rotation angle calibrating installation.
Background technology
In the prior art, the steering engine of robot is operated using potentiometer as steering engine angle sensor unit, when steering engine control
Since the resistance value curve of each potentiometer is not fully identical when system is adjusted the angle according to the resistance value of potentiometer, rotation angle and resistance
Value is not in a linear relationship, and the rotation angle for resulting in steering engine has deviation, and the action for causing robot is stiff, uncoordinated.
Utility model content
The purpose of this utility model is that：A kind of steering engine that can calibrate potentiometer resistance numerical value corresponding with rotation angle is provided
Rotation angle calibrating installation.
A kind of steering engine rotation angle calibrating installation, including steering engine, grating encoder, microcontroller, shaft coupling, stent, current potential
Device, the steering engine are fixed in stent, and the steering engine includes steering engine communication port, steering engine main shaft, and the potentiometer is fixed in steering engine master
Axis, the grating encoder include grating disc, photoelectric sensor, and the grating disc is located on the groove of photoelectric sensor, described
Photoelectric sensor is connected to steering engine communication port by microcontroller, and described shaft coupling one end connects through grating disc to stent, the other end
It is connected to steering engine main shaft.
Preferably, the section of the stent is L-type.
Preferably, the potentiometer, shaft coupling, grating disc are located at same axis.
The helpfulness of the utility model is：When needing that steering engine is controlled to be rotated, the microcontroller can be directly in
The resistance value of the potentiometer in portion with its corresponding to the recording of rotation angle, the resistance value of current potentiometer carries out rotation control, avoid
The problem of curve of potentiometer resistance is not exactly the same, after calibration, is not influencing original steering engine structure and is not increasing rudder
The precision of steering engine is improved on the basis of machine cost.
Description of the drawings
Fig. 1 is the utility model structure diagram.
Specific embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with attached drawing.
A kind of steering engine rotation angle calibrating installation, comprising steering engine 1, grating encoder 2, microcontroller 3, shaft coupling 4, stent 5,
Potentiometer 6, the stent 5 are L-type, and the steering engine 1 is fixed in stent 5, and steering engine 1 includes steering engine communication port 101, steering engine main shaft
102, the potentiometer 6 is fixed on steering engine main shaft 102, and potentiometer 6 can be rotated synchronously with steering engine main shaft 102, the grating
Encoder 2 includes grating disc 201, photoelectric sensor 202, and the grating disc 201 is located in the groove of photoelectric sensor 202, institute
It states photoelectric sensor 202 and steering engine communication port 101 is connected to by microcontroller 3, one end of the shaft coupling 4 passes through grating disc 201
Stent 5 is fixed in, the other end is connected to steering engine main shaft 102.
When the grid of grating disc 42 often detects a lattice of passing by, the level meeting of photovoltaic converter 202 by photovoltaic converter 202
Once, and its saltus step information is transferred to microcontroller 3 for height saltus step, and the I/O port of the microcontroller 3 generates the height of corresponding number
Level saltus step, the timer inside the microcontroller 3 counts the transition times of I/O port low and high level, because of remembered number of transitions
Value is in a linear relationship with the rotational angle of steering engine main shaft 102, can be worth corresponding angle according to number of transitions, electricity during calibrating herein
The resistance value and the rotation angle corresponding to it of position device 6 are recorded in microcontroller 3, described when needing that steering engine is controlled to be rotated
Microcontroller 3 can be directly according to corresponding to the resistance value of internal potentiometer 6 with it the recording of rotation angle, current potentiometer 6
Resistance value carries out rotation control.
