Problems solved by technology

[0003] Therefore, in harsh environments, people usually choose magnetic encoders. Magnetic encoders are easy to install, eliminate the need for couplings, have strong anti-interference ability, and are not afraid of vibration. The disadvantage is that the current technology cannot make the resolution very high.

Embodiment Construction

[0026] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0027] The invention provides a manufacturing method and tooling for a high-precision magnetic encoder magnetic ring. The tooling can be called a magnetizing machine, which contains a magnetizing coil.

[0028] Such as Figures 1 to 4 As shown, a high-precision magnetic encoder magnetic ring manufacturing tooling includes an upper template 7 and a lower template 6 for guiding and positioning, and a magnetic ring for positioning the magnetic ring at the joint surface of the upper template 7 and the lower template 6. The ring positioning plate 3 is respectively arranged on the upper coil 1 and the lower coil 2 located above and below the magnetic ring positioning plate 3 in the upper template 7 and the lower template 6, and the upper coil 1 and the lower coil 2 form an upper and lower pair of charging coils.

Abstract

The invention discloses a manufacturing method and tool of a magnetic ring of a high-precision magnetic encoder, which are used for manufacturing the magnetic ring of the magnetic encoder. The tool comprises coils located above and under the magnetic ring; the two coils are magnetizing coils with a plurality of poles; with the adoption of a magnetizing manner, the precision of the magnetic ring can be improved and a non-magnetic region between the poles of the magnetic ring can be relatively thin, so that the quantity of the poles of the magnetic ring is improved and the resolution of the magnetic encoder is also improved; and the uniformity between the poles also can be improved.

Description

technical field [0001] The invention relates to the manufacture of a magnetic ring of a magnetic encoder, in particular to a manufacturing method and tooling for a magnetic ring of a magnetic encoder with high precision. Background technique [0002] An encoder is a device that compiles and converts a signal (such as a bit stream) or data into a signal form that can be used for communication, transmission, and storage. Encoders are divided into photoelectric encoders and magnetic encoders; optical encoders are precise but have higher protection requirements for outdoor and harsh environments; the measurement of linear displacement depends on the conversion of mechanical devices, and the error caused by mechanical gaps needs to be eliminated; Detecting orbiting objects is difficult to overcome slippage. [0003] Therefore, in harsh environments, people usually choose magnetic encoders. Magnetic encoders are easy to install, eliminate the need for couplings, have strong anti-...
