Abstract
The utility model relates to a rotary encoder for an ultra-thin servomotor, belonging to the technical field of automated measuring installation. The rotary encoder is characterized in that a photoelectric reader with high integration density is installed on an electronic circuit board; a main shaft is supported inside the main body through a bearing; a grating is installed on a grating disc seat; a shell is installed on the main body, and a road spring is fastened on the main body and is fixed on the installation interface of a user through two kidney holes on the road spring by means of bolts. The rotary encoder is simple, compact and reasonable in structure; the circuit is simple with adjustable technological parameters and steady and reliable output signals; when the grating begins to rotate, the photoelectric reader with high integration density receives and then converts the signals on the grating disc to digital electrical signals; with the process of a simple drive circuit, codes on the grating disc are outputted in the form of rectangular waves, thus accomplishing conversion from mechanical movement physical parameters(position, velocity and acceleration) to figures and the feedback of the cooperation of the U.V.W signals with the magnetic pole of the servomotor.
Description
Technical field
The utility model relates to a kind of ultra-thin servomotor rotary encoder, specifically is applied in the automation control system, is particularly suitable for and the servomotor supporting use of encoder, belongs to the automatic measurement mechanism technical field.
Background technology
Rotary encoder comes across China's eighties of last century sixties as a kind of transducer.Develop its application through many decades and progressively be diffused into civilian industry department by defence and military department.As be diffused into the application on Digit Control Machine Tool, robot, servomotor by application on military vehicle radar, artillery command instrument, aerospace craft.The signal reading mechanism of conventional servomotor encoder is comparatively complicated, the signal reading section is selected discrete part for use, this type of encoder is when making, technology is complicated, volume is bigger, and " U ", " V ", " W " and phase signal are difficult for obtaining, and the signal of obtaining a little less than, need processing through shaping amplification circuit, can output signal.Its poor anti jamming capability, main structure body partly adopt machining mode, and cost of manufacture is also higher.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provide a kind of ultra-thin servomotor encoder, signal on the grating dish directly can be extracted and change into digital electric signal, its circuit is simple, the production assembly technology is simple, output signal accuracy is high, good stability.
Main solution of the present utility model is achieved in that
The utility model mainly adopts electronic circuit board is housed in main body, feature is that the photoelectric reader of high integration is contained on the electronic circuit board, housing and main shaft are contained on the main body, and main shaft is bearing in the main body by bearing and cooperates installation with grating dish seat, on grating dish seat grating is installed.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Its circuit is simple, the production assembly technology is simple, output signal accuracy is high, good stability, and technological parameter can be adjusted; Photoelectric reader by high integration after grating rotates will access signal on the grating dish and change into digital electric signal, through the code on the simple processing of circuit reflection grating dish with the output of square wave group, thereby finished the feedback that is used to the conversion of digital quantity (A.B.Z) and U.V.W signal and servomotor magnetic pole by mechanical movement physical quantity (position, angle).
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly is made up of main shaft 1, leaf spring 2, main body 3, bearing 4, grating dish seat 5, photoelectric reader 6, grating 7, luminous tube 8 and housing 9 etc.
The utility model adopts and in main body 3 electronic circuit board is housed, the photoelectric reader 6 of high integration is contained on the electronic circuit board, and main shaft 1 is bearing in the main body 3 by bearing 4, and grating 7 is installed on grating dish seat 5, housing 9 is installed on main body 3, and leaf spring 2 is fastened on the main body 3.
When user's axle rotated, the main shaft 1 of this product (grating 7) also rotated thereupon synchronously, and the photoelectric reader 6 of high integration is a digital signal with the code conversion on the grating 7, again through driving output.This product standing part is to be screwed on the end face of user installation by two mounting holes on the leaf spring 2.
Operation principle of the present utility model
When user's axle rotated, the main shaft 1 of this product (grating 7) also rotated thereupon synchronously, and the photoelectric reader 6 of high integration is a digital signal with the code conversion on the grating 7, exported with square wave through the code that simple drive circuit is handled on the reflection grating dish.The output of this signal has promptly comprised the information of user's axle motion state and the state of user's motor pole (U.V.W), has finished the feedback that is used to the conversion of digital quantity and U.V.W signal and servomotor magnetic pole by mechanical movement physical quantity (position, speed, acceleration).
