It is understandable to enable the above objects, features and advantages of the present invention to become apparent, below in conjunction with the accompanying drawings to the present invention
Specific embodiment be described in detail.
First embodiment
With reference to figure 1-3, the present embodiment provides a kind of magnetism encoder 100, including support 1, rotating shaft 2, bearing 3, the He of read head 4
Code-disc 5.
Wherein, support 1 is provided with through hole, and the column 11 of more than two is provided with the side of support 1, the column 11
It is highly identical, and all perpendicular to the support 1.Moreover, screwed hole is provided with the column 11, for being connected with read head 4.
The through hole set on support 1 is used to house rotating shaft 2 and bearing 3.In the present embodiment, the support 1 is square,
The through hole set on support 1 is circle, and the axis of the through hole on support 1 is perpendicular to support 1, and passes through the center of support 1.
The quantity of the column 11 is more than two, can generally set three or four, the column 11 is used to connect
Read head 4 is connect, the height of the column 11 is identical, and, for ensuring after installing read head 4, can all ensure perpendicular to the support 1
Read head 4 is parallel to support 1.
In the present embodiment, the quantity of the column 11 is 4, is uniformly distributed along support 1 is circumferential.It is vertical shown in Fig. 1
Post 11 is separately positioned on the position at four angles of support 1.
Be provided with connecting hole on the read head 4, using screw 2A through connecting hole and with the screw thread on corresponding column 11
Hole connects, and after read head 4 is connected with column 11, the central axis of through hole of the center line axis of read head 4 with being set on support 1 overlaps.
After ensureing that read head 4 is connected with column 11, center line axis and the central shaft of the through hole set on support 1 of read head 4
Line overlaps, it is only necessary to and it is rational that column 11 is set when producing magnetism encoder, and connection is set on the appropriate location of read head 4
Hole.That is, the present embodiment provide magnetism encoder after manufacturing, user using when only need by screw will
Read head 4 is connected with column 11, you can ensures that the central axis of through hole of the center line axis of read head 4 with being set on support 1 overlaps.
