Embodiment 1

[0033] Such as figure 1 , 2 As shown, a flexible magnetic scale with a circular cross-section without a substrate provided by the present invention includes a magnetic scale body 1 after magnetic recording along a 360° direction, and the magnetic scale body 1 includes a flexible magnetic part 2 and a protective cover 3 , the cross-section of the flexible magnetic part 2 is circular, and the outer side of the flexible magnetic part 2 is covered with the protective cover 3; the present invention has no substrate, can ensure flexibility, and can record magnetic fields along a 360° direction; the existing magnetic Generally, the substrate of the gate is made of metal material. Even a flexible substrate (usually a stainless steel strip) cannot be flexible in 360-degree directions, so that 360-degree magnetic recording cannot be performed, and the signal may be lost when it is bent. When the present invention records magnetically, it is necessary to rotate the magnetic scale at one...

Abstract

The invention discloses a flexible non-matrix circular cross section magnetic grating ruler, which comprises a magnetic grating ruler body after magnetic recording along a 360-DEG direction. The magnetic grating ruler body comprises a flexible magnetic part and a protective sleeve, wherein the flexible magnetic part has a round section; and the protective sleeve coats the flexible magnetic part. The technical problem that the magnetic grating ruler can only perform linear measurement but can not measure a curve in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of magnetic gratings, in particular to a flexible baseless circular cross-section magnetic grating ruler and its application and usage method. Background technique [0002] The magnetic grid is a high-precision position detection device, which consists of a magnetic scale, a magnetic pickup head and a detection circuit. It works on the principle of magnetic pickup. First, use the recording head to record a square wave or sine signal of a certain wavelength on the magnetic scale, and then detect the displacement based on the signal picked up by the pickup head that is displaced relative to the magnetic scale. The magnetic ruler can be used for length and angle measurement, and has the advantages of high precision, simple operation and convenient installation and adjustment. [0003] The magnetic grid was successfully developed in the middle of the 1950s. It is used to measure the error of the transmission c...
