Description
Technical field
The utility model relates to a kind of ultrathin tubular shaft individual pen serial absolute type magnetoelectricity shaft-position encoder, specifically is applied to electrical equipment servo-drive system and automatic control system as detecting element or feedback element.
Background technology
Single-ring absolute type optical electric axial angle encoder main application fields is permanent magnetic Ac servo motor, the control of hydrology sluice, the angle position measurement of space flight and aviation equipment etc.; Main industries are textile machine, light industry and machinery, office automation, reservoir strobe control, Aero-Space, industrial control automation etc.Optical electric axial angle encoder comes across China's eighties of last century sixties as a kind of sensor.Develop its application through many decades and progressively be diffused into civilian industry department by defence and military department.As on military vehicle radar, artillery command instrument, aerospacecraft, using the application that is diffused on numerically-controlled machine, robot, motor.
In prior art, common single-ring absolute type optical electric axial angle encoder mainly adopts the Photoelectric Detection scheme of photoelectric cell, photoelectric tube, owing to its structure, adopt the restriction of components and parts and configuration, can only produce the bigger absolute type encoder of diameter.That its production technology assembling and setting difficulty, circuit are formed is complicated, yield rate is low, volume is big, the many poor anti jamming capability of output line, poor reliability, and environment for use requires harsh, and oil rub resistance, anti-vibration ability are also relatively poor.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of ultrathin tubular shaft individual pen serial absolute type magnetoelectricity shaft-position encoder is provided, and has adopted novel, efficient, high integration magnetoelectricity device, and is anti-interference, the anti-vibration ability is strong; Can improve the product row yielding for the user saves the space, and can reduce cost.
Main solution of the present utility model is achieved in that
The utility model mainly adopts housing to be installed on the main body, and cable or plug cable are installed on housing, and feature is that main shaft is installed in the main body by bearings, at main-axis end disk is installed, and disk is combined as a whole with axle system; The magnetoelectricity assembly is installed in main body, and leaf spring is fastened on the main body.
Described main shaft is a hollow-core construction.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Produce assembly technology simple, need not debugging; Individual pen resolution resolution on the scrambler of minimum diameter ￠ 22 can reach 13, and volume-diminished is more than one times on year-on-year basis; Adopt serial SSI output, antijamming capability is strong; Be applied to the rugged surroundings oil rub resistance, shock resistance is strong; Can improve the product row yielding for the user saves the space, and can reduce cost.

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, bearing 3, main body 4, housing 5, disk 6, magnetoelectricity assembly (wiring board) 7 and cable or plug cable 8 etc.
The utility model is made up of three parts altogether, i.e. pivotable parts axle system, fixed part magnetoelectricity assembly, main body and circuit part.Main shaft 1 supports by bearing 3 and is installed in the main body 4, at main shaft 1 axle head disk 6 is installed, and disk 6 is combined as a whole with axle system; Pivotable parts is that rotary axis has adopted main shaft bearing frequency modulated light grid holder shelves to make the glue filling trough fastening structure; Freely rotate by bearings between the main body 4 of disk 6 and fixed part.Housing 5 is installed on the main body 4, and cable or plug cable 8 are installed on housing 5, all is screwed.User's axle and this product main shaft 1 (being disk 6) connect, and when user's axle rotated, the main shaft of this product (disk 6) also rotated thereupon synchronously.Fixed part is to be fastened on the main body 4 by leaf spring 2, and leaf spring 2 is screwed on the end face of user installation.
The utility model principle of work:
Be fixed with a disk 6 on the utility model main shaft (grating dish seat) 1, N, the S utmost point arranged according to certain rule on the disk 6.When user's axle rotates drive this product main shaft (grating disk) 1 rotation synchronously, disk 6 also rotates thereupon, at this moment integrated magnetoelectricity assembly (wiring board) 7 will be an electric signal with N, S utmost point change transitions on the disk 6, and the logical circuit of forming by the electron device on the integrated magnetoelectricity assembly (wiring board) 7 is treated as serial SSI output again.This signal output has promptly comprised the information of user's axle motion state, has finished by the conversion of mechanical motion physical quantity (position, speed, acceleration) to electric weight.
The utility model circuit theory:
The utility model disk 6 is arranged N, the S utmost point according to certain rules, the magnetoelectricity assembly carries out data acquisition to the N of spinning disk 6, the variation of the S utmost point, form the electric current of analog sine, the magnetoelectricity component internal is amplified the shaping data computation to electric current and is processed into electric signal, electric signal again through after one-level amplify shaping, the computing of logical circuit IC chip signal, the code of the absolute positions such as binary code of promptly exportable reflection user rotating shaft absolute position.The user also can handle use according to this serial SSI output in subsequent conditioning circuit.
