Problems solved by technology

[0003] However, since the edges of the connecting parts of the buckle 200 are straight edges, and the two connecting parts of the buckle 200 are parallel to each other after installation, the distance between the magnetic strip 100 and the testing shaft 400 is close to the position where the connecting parts fit the testing shaft 400 . There will be a gap 500 between them (that is, partial warping), which will cause the magnetic strip 100 to fail to fit the test axis 400, so that the read head cannot accurately read the signal of the lifted part of the magnetic pole, causing the magnetic encoder to measure the test axis 400. Larger data fluctuations will occur at a higher speed, which will affect the normal performance of the magnetic encoder

Embodiment 1

[0024] The invention provides a buckle which can prevent the magnetic strip from lifting, combined with Figure 3 ~ Figure 5 As shown, the buckle includes: two connecting pieces 1 and a steering piece 2, the lower end of the connecting piece 1 has a connecting groove 11, and the steering piece 2 includes: two relatively rotatable rotating blocks 21, a rotating block 21 and a connecting piece 1 to form a fixed connection, and the other rotating shell 21 is engaged with another connecting piece 1 to form a fixed connection.

[0025] Such as Image 6 As shown, the magnetic strip 100 of the magnetic encoder includes: a magnetic tape 101, a plurality of magnetic poles 102 with a length of 5mm (along the length direction L) and two steel tape backings 103, and the plurality of magnetic poles 102 includes a plurality of N magnetic poles and a plurality of magnetic poles. A plurality of S poles, a plurality of magnetic poles 102 are arranged in a row in the middle of the magnetic tap...

Embodiment 2

[0036] In this example, if Figure 8 As shown, the buckle structure is similar to that of Embodiment 1, the difference is that the widths (and the same shapes) of the two connecting pieces 1 are equal. Wherein, one end of one connecting piece 1 is engaged with the rotating block 21 on the outside of one steering piece 2 to form a fixed joint, and the other end is engaged with the rotating block 21 on the inside of another turning piece 2 to form a fixed connection; one end of another connecting piece 1 is connected to a The inner rotating block 21 of the steering member 2 is engaged to form a fixed position, and the other end is engaged with the outer rotating block 21 of another steering member 2 to form a fixed position. For the above structure, the same set of molds can be used to produce the connecting piece 1, and there is no need to set two different sets of molds (that is, with different molding widths), thereby reducing the manufacturing cost.

Abstract

The invention discloses a buckle capable of preventing a magnetic strip from tilting. The buckle comprises two connecting pieces (1) and a steering piece (2), wherein connecting grooves (11) are formed in the lower ends of the connecting pieces (1); the steering piece (2) comprises two rotating blocks (21) capable of rotating relatively; one rotating block (21) is connected to one connecting piece (1) to form fixation; and the other rotating block (21) is connected to the other connecting piece (1) to form fixation. The buckle of the structure can enable the magnetic strip of an encoder to be completely attached to a test shaft, so that local tilting is avoided, and the normal operation of the magnetic encoder is guaranteed; and in addition, the buckle can be suitable for encoders with different shaft diameters, and the universality is good.

Description

technical field [0001] The invention relates to a magnetic encoder, in particular to a buckle which can prevent the magnetic strip from lifting. Background technique [0002] A magnetic encoder is usually composed of a test shaft, a magnetic strip and a read head, and is a sensor used to measure the rotational speed of a large shaft diameter test shaft. Such as figure 1 As shown, the magnetic strip 100 is usually provided with a buckle 200, and the buckle 200 has two connecting parts. Fixed connection, so that the magnetic strip 100 is fixed on the circumference of the testing shaft 400 . [0003] However, since the edges of the connecting parts of the buckle 200 are straight edges, and the two connecting parts of the buckle 200 are parallel to each other after installation, the distance between the magnetic strip 100 and the testing shaft 400 is close to the position where the connecting parts fit the testing shaft 400 . There will be a gap 500 between them (that is, par...
