Description

Technical Field

[0001] The utility model relates to the technical field of mounting fixtures, in particular to a mounting fixture for a magnetic grating reading head. Background Art

[0002] The working principle of magnetic grating is magneto-electric conversion. In order to ensure that the magnetic head has a stable output signal amplitude, considering the large magnetic resistance of air, a large and variable gap is not allowed between the magnetic scale and the magnetic head, and it is best to be in contact. For this reason, the magnetic head of the belt-type magnetic grating is pressed onto the magnetic tape when it is working, so that even if the tape surface is a little uneven, the magnetic head and the magnetic tape can still have good contact. There is a gap of about 0.01mm between the magnetic scale and the magnetic head of the linear magnetic grating. Since it is impossible to achieve the ideal state during assembly and adjustment, the linear magnetic grating is actually in a quasi-contact working state. The magnetic grating reading head is an important part of the magnetic grating, and the magnetic grating reading head needs to be installed and fixed when in use.
