The utility model is characterized in that a rolling wheel and an incremental encoder are arranged on a rolling wheel frame. The rolling wheel frame is connected with a mechanicalmember and is arranged on a seat frame; a position trigger is sucked on the measured rotary body, and a position sensor is arranged beside the measured rotary body; the position sensor and the incremental encoder which are connected with a microcomputer via a cable share the same direct current power supply. Therefore, the measurement precision of the novel diameter measuring apparatus is enhanced. Moreover, the utility model has the advantages of simple operation, light self weight and low cost, and the novel diameter measuring apparatus is favorable to being generalized and applied.
Description
The utility model is the measurement mechanism of a kind of measurement major diameter (above 500 millimeters) garden shape thing diameter in rotation, the kinetic measurement of rotary kiln tyre in particularly suitable cement, metallurgy and the chemical industry and support roller diameter.
The diameter measuring device of existing rotary kiln tyre and support roller, measuring accuracy is low, and heavy.In " going back to the kiln center with laser determination " book, once described a kind of band and support roller measuring diameter instrument of taking turns in detail, it mainly is made up of roller, counter axis, electromagnetic clutch, mechanical counter and mechanical fastener etc., this analyzer not only volume is big, and very heavy, and power supply also is restricted, must use the 220V AC power, simultaneously, because it adopts electromagnetic clutch and mechanical counter, so it is low to measure the precision of diameter, be about ± 8 millimeters, so very inconvenient in measurement.
The utility model goes wrong at above-mentioned, provide a kind of measurement handled easily simple, improve measuring accuracy, portable rotary kiln tyre and support roller diameter measuring device.
The primary structure of measurement mechanism of the present utility model is: roller and counter scrambler are housed on turning rolls, and roller and its central shaft are connected as a single entity, and their counter roller framves can rotate freely.The counter scrambler is a kind of electromechanical device that can be converted to the rotation angle displacement digital quantity signal with being directly proportional.Scrambler and roller at this have following relation: when roller revolves when turning around, scrambler is exported the electric pulse square wave digital signal of a certain fixed value by its cable.Turning rolls is connected by several mechanical components, and is contained on the mounting.The period measurement device of rotary body is made up of location trigger and position transducer.When the approaching process of location trigger position transducer, position transducer will send an electric impulse signal to microcomputer by cable.Position transducer directly is connected with microcomputer by cable respectively with the counter scrambler.A direct supply is to all electric component power supplies.Its characteristics are to have used counter scrambler and rotary body period measurement device, and they connect by cable and a microsystem respectively, their shared direct supplys.
The counter coder that the utility model adopts should meet the following conditions at least: when the roller external diameter turns over 0.5 millimeter arc length, digital signal corresponding just can be differentiated, discerns and be write down to counter scrambler and microcomputer.For make the error of measuring diameter be less than or equal to ± 0.2 millimeter, the counter scrambler should preferentially be selected the incremental encoder of angular displacement segmentation for use.The technical conditions that this scrambler must satisfy be: when roller revolves when turning around, scrambler is exported the electric pulse digital signal of a fixed value to microcomputer, and the numerical value of this signal should be more than or equal to 2 times of roller external diameter girth (millimeter unit) numerical value.After adopting this scrambler, circuit part of the present utility model is just very simple, its primary structure characteristics are: adorning roller and incremental encoder on the turning rolls, roller and its axle is connected as a single entity, the axle of incremental encoder and roller spool by coaxial linking of flexible clutch.Turning rolls can rotate around a certain stationary shaft by some mechanical component, and under the effect of a spring device, roller is contacted always closely with tested rotary body.Certainly, under the measuring accuracy situation of less demanding (being about ± 1.5 millimeters), the counter scrambler also can adopt the incremental encoder of position, angle-time segmentation, this scrambler can not link with roller shaft, but its circuit will be comparatively complicated, need design specialized microcomputer software program, the entire circuit debugging work load is big.When using this device to measure, require tested rotary body at the uniform velocity to rotate; Can not speed change rotation, temporary transient stall or counter-rotating, can't carry out otherwise measure.
In the utility model device, because roller external diameter girth is used as station meter, so require its external diameter value under various mal-conditions, all to keep well stability, therefore should select for use wear-resisting and the minimum metal material of temperature expansion coefficient, preferably select the indium steel in the stainless steel-like for use.The external diameter of roller is about 100 millimeter.
In the utility model device, it is characterized in that: the period measurement device of rotary body is to be made of a location trigger and a two-value type electricity type position transducer.This location trigger is the metal object of a band permanent magnet, and it can stably be adsorbed on the side of tested rotary body.This position transducer is a non-contacting electromagnetic proximity switch, and it is being supported by dial framework.
When using the utility model to measure, earlier location trigger is inhaled side at tested rotary body, position transducer stably is positioned on the position of location trigger rotation process with dial framework, this measurement mechanism is installed in by the tested rotary body, by mechanical fastener roller is contacted closely with the measured object diametral plane always, keep PURE ROLLING.With cable all electric component connection are linked up, turn on the power switch, just can measure.Principle of work of the present utility model is: when the location trigger of suction in the measured object side rotated through position transducer, this sensor just sent a square-wave signal to microcomputer, the umber of pulse of microcomputer opening entry scrambler output this moment.When location trigger revolved the square-wave signal that the microcomputer that turns around receives that again sensor sends, microcomputer just stopped the umber of pulse of record coding device.Microcomputer revolves the pulse sum m of scrambler output when turning around by the record measured object like this, just can calculate the diameter phi of rotary body by following formula:
φ＝ (m×p)/(π)
P is a scrambler when producing a umber of pulse in the formula, the arc length value that roller external diameter correspondence turns over.In order to reduce measuring error, generally to gather measured object and change the above data of 5 circles, calculate its mean value then.
The utility model has the advantages that, adopted incremental encoder and period measurement device, greatly the measurement mechanism of Jian Huaing.Because the roller external diameter is when turning over 1 millimeter arc length, scrambler is just exported 2 pulses, and the time error of period measurement device measuring period is less than ± 0.5 millisecond, thus this measurement mechanism measure the theoretical error of rotary body diameter will be less than 0.2 millimeter.Owing to used microsystem, this device can store, calculate, show measurement result automatically, and can calculate the mean value of repeatedly measuring.This installs light small and exquisite, and is simple to operate, and low cost of manufacture is easy to utilize.
