Abstract

The utility model discloses a medium and high precision magnetic encoder. The magnetic encoder comprises a cavity, wherein a cover board is installed at the bottom of the cavity; a rotating shaft and a circuit board are installed in the cavity; one end of the rotating shaft is positioned outside the cavity, magnetic steel is installed at the other end of the rotating shaft; a magnetic chip corresponding to the position of the magnetic steel is installed on the circuit board; the distance between the magnetic steel and the magnetic chip is 0.5-2mm; and the circuit board is fixedly connected with an outer connector. The magnetic encoder not only has good sealability, little damage, good interference resistance and long service life but also has little shock, wide range of application, high precision and strong reliability and can achieve 1000-4000 threads/r.

Description

High precision magnetic coder in a kind of
Technical field
The utility model relates to a kind of middle high precision magnetic coder.
Background technology
At present, use to Weaving device on the measurement of carrying out rotating speed, angle and position of the axle that is rotated often be difficult to accomplish that precisely generally the method for employing is that inductor directly is installed on axle; Through mounting bracket around it, the corresponding completion surveying work of sensing apparatus is installed on support then, is that is to say; During each the measurement; Install loaded down with trivial detailsly, and exist because of laying distance at every turn, the different and error of generation of angle.And poor anti-interference, serviceable life is short.
The utility model content
The purpose of the utility model is to provide a kind of middle high precision magnetic coder, the utility model.The utility model is good airproof performance not only, and damage is down, and is anti-interference good, long service life, and shake for a short time, and usable range is wide, and precision is high, can reach 1000-4000 line/commentaries on classics, good reliability.
In order to reach above-mentioned purpose, the solution of the utility model is:
High precision magnetic coder in a kind of comprises cavity, and cavity bottom is equipped with cover plate; Turning axle and wiring board are installed in the described cavity, and turning axle one end is positioned at outside the cavity; The described turning axle other end is equipped with magnet steel; The magnetic chip corresponding with the magnet steel position is installed on the described wiring board, and the distance between magnet steel and the magnetic chip is 0.5-2mm; Wiring board and external tapping are connected.
Be movably installed with turning axle through 2 bearings in the described cavity.
On the spindle nose of the described turning axle other end magnet steel is installed.
Offer mounting hole on the described cavity.
The beneficial effect of the utility model is: the equipment of the utility model adopts the metallic seal cavity, and adopts magnet steel and magnetic piece induction, rotating speed, angle and the position of the different textile machine equipment of energy measurement measured axis; Not only good airproof performance is under the damage, anti-interference good; Long service life, and shake for a short time, usable range is wide; Precision is high, can reach 1000-4000 line/commentaries on classics, good reliability.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Embodiment 1
As shown in Figure 1, a kind of middle high precision magnetic coder of present embodiment comprises metallic cavity 1, and cavity 1 bottom is equipped with cover plate 2; Turning axle 4 and wiring board 5 are installed in the described cavity 1, and turning axle 4 one ends are positioned at outside the cavity 1; Described turning axle 4 other ends are equipped with magnet steel 6; The magnetic chip 7 corresponding with magnet steel 6 positions is installed on the described wiring board 5, and the distance between magnet steel 6 and the magnetic chip 7 is 0.5-2mm; Wiring board 5 is connected with external tapping 8.Be movably installed with turning axle 4 through 2 bearings 3 in the described cavity 1, duplex bearing connects the stability that improves its turning axle.On the spindle nose of described turning axle 4 other ends magnet steel 6 is installed.Offer mounting hole 9 on the described cavity 1.During use; The measured axis of turning axle 4 with tested device flexibly connected; Turning axle 4 just can follow measured axis to rotate synchronously, rotates thereby drive magnet steel 6, causes magnet steel 6 changes of magnetic field on every side; Magnetic chip receives to be transferred to wiring board 5 behind the magnetic field variation signal and to be converted into digital signal and links to each other through output devices such as external tapping 8 and computing machines, so signal is transferred out.The equipment of present embodiment adopts the metallic seal cavity, and adopts magnet steel and magnetic piece induction, rotating speed, angle and the position of the different textile machine equipment of energy measurement measured axis; Not only good airproof performance is under the damage, anti-interference good; Long service life, and shake for a short time, usable range is wide; Precision is high, can reach 1000-4000 line/commentaries on classics, good reliability.
