Description
Technical field
The utility model relates to geometric measurement instrument, and particularly a kind of different between centers of transmission ratio-variable connects angel measuring instrument.
Background technology
Current domestic and international existing angel measuring instrument, have plenty of and use logic digital circuits chip to realize, also have plenty of with single-chip microcomputer do core devices realize, no matter that is a kind of, they also exist installation and inconvenient problem with use, because the zero degree pulse signal of measured axis all takes from same rotary encoder, and recurrent pulse number needs setting in advance.And require rotary encoder must be arranged on measured axis or be arranged on engagement than on other axle for 1:1.
Utility model content
The purpose of this utility model is to provide a kind of angel measuring instrument, and angel measuring instrument is easy to install and use, and measuring accuracy is high, can see the angle turned over of rotating shaft very intuitively, can provide position accurately for measurement of correlations such as experiment of dynamic balancing.
The purpose of this utility model is achieved through the following technical solutions:
The different between centers of transmission ratio-variable connects an angel measuring instrument, and described angel measuring instrument comprises rotary encoder, phase demodulating, frequency doubling module, photoelectric sensor, zero testing module, Puzzle lock storing module, single chip control module, keyboard display module; Wherein: rotary encoder and phase demodulating, frequency doubling model calling, photoelectric sensor and zero testing model calling, phase demodulating, frequency doubling module is connected with Puzzle lock storing module jointly with zero testing module, Puzzle lock storing module is connected with single chip control module, and keyboard display module is connected with single chip control module.
As preferred technical scheme, described photoelectric sensor is OC-MR3212NA type optoelectronic switch, and its input voltage is 12V, and output current is 100mA.
Advantage of the present utility model:
Angel measuring instrument described in the utility model is easy to install and use, and measuring accuracy is high, can see the angle turned over of rotating shaft very intuitively, can provide position accurately for measurement of correlations such as experiment of dynamic balancing, have good effect in actual applications.
Accompanying drawing explanation
Fig. 1 is that a kind of different between centers of transmission ratio-variable connects angel measuring instrument theory structure schematic diagram.
Embodiment
below in conjunction with drawings and the embodiments, the utility model is described in further detail:
The feature of this angel measuring instrument:
(1) measured axis and coding axle can disalignments;
(2) ratio of gear of measured axis and coding axle is a meaning ratio;
(3) when rotating speed exceedes preset value, the state of testing the speed can be automatically switched to;
(4) can be arranged the zero-bit angle of measured axis easily by software, this design can paste cursor at an arbitrary position, arranges zero-bit angle by software, reduces personal error, improves measuring accuracy.The current data recorded can be locked at any time, convenient viewing and record.
The technical indicator of this angel measuring instrument:
(1) scrambler allows maximum (top) speed: 5000r/min;
(2) scrambler staring torque: 1.5X10-3N.m;
(3) scrambler allows angular acceleration: 10000rad/s2;
(4) angle measurement accuracy: 0.5 ± 0.1 degree;
(5) range rate error: be less than 0.07%.
The different between centers of transmission ratio-variable connects an angel measuring instrument, and described angel measuring instrument comprises rotary encoder 1, phase demodulating, frequency doubling module 2, photoelectric sensor 3, zero testing module 4, Puzzle lock storing module 5, single chip control module 6, keyboard display module 7; Wherein: rotary encoder 1 is connected with phase demodulating, frequency doubling module 2, photoelectric sensor 3 is connected with zero testing module 4, phase demodulating, frequency doubling module 2 is connected with Puzzle lock storing module 5 jointly with zero testing module 4, Puzzle lock storing module 5 is connected with single chip control module 6, and keyboard display module 7 is connected with single chip control module 6.
Described photoelectric sensor 3 is OC-MR3212NA type optoelectronic switch, and its input voltage is 12V, and output current is 100mA.
Processing the output signal of rotary encoder of phase demodulating, frequency doubling module, makes it to identify forward and reverse, and exports the signal of two frequencys multiplication, and provides plus-minus counting pulse for Puzzle lock storing module below.Zero testing module to the output signal of photoelectric sensor carry out shaping, oppositely, the process such as differential, make it the zero signal obtaining measured axis accurately, be supplied to Single Chip Microcomputer (SCM) system and carry out demarcating and counter O reset.Puzzle lock storing module is used for the zero signal that the umber of pulse that turns over of record coding device and photoelectric sensor are surveyed, and by latching chip and realize and the data communication of single-chip microcomputer.Single Chip Microcomputer (SCM) system is the heart of whole system, and its commander's whole system realizes the measurement of different axle indirect angle.
