Abstract
The utility model relates to magnetic steel, in particular to NdFeB (neodymium iron boron) magnetic steel used for instruments. The NdFeB magnetic steel comprises a magnetic steel body, the middle of the magnetic steel body is provided with a square assembling hole, friction strips are uniformly distributed on the inner wall of the assembling hole, a displacement transmission sensor is arranged in the magnetic steel body, the magnetic steel body is made of NdFeB magnetic steel, and a nickel-plated layer covers the surface of the magnetic steel body. The NdFeB magnetic steel used for the instruments is compact in structure, product performance is improved, and service life is prolonged.
Description
Technical field
The utility model is a kind of magnet steel, particularly a kind of Nd-Fe-B magnet steel for instrument.
Background technology
Magnet steel of the prior art, complex structure, and also fixed form is insecure, and result of use is not good, causes reduce its useful life.
Chinese patent 201020150678.5, discloses a kind of magnet, particularly a kind of samarium cobalt magnet with cambered surface that is mainly used in microwave communication technology, audio-visual technology, electrical engineering etc.Comprise magnet, described magnet pack is drawn together contour body and square body, and described contour body and square body are integrated, in described magnet, are provided with intermediate layer, and intermediate layer is coated with nickel coating.This structure relative complex, useful life is relatively low.
Summary of the invention
The utility model is mainly to solve the deficiencies in the prior art, compact conformation, and lifting assembly precision greatly promotes the Nd-Fe-B magnet steel for instrument of transducer serviceability simultaneously.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of Nd-Fe-B magnet steel for instrument, comprise magnet steel, the interposition of described magnet steel is provided with square installation opening, the inwall of described installation opening is provided with equally distributed fricting strip, in described magnet steel, be provided with displacement emission sensor, the material of described magnet steel is Nd-Fe-B magnet steel, and the surface of described magnet steel is covered with nickel coating.
Displacement emission sensor: when the displacement occurring in motor when magnet steel exceedes, displacement emission sensor is sent signal to control centre.
As preferably, the diameter of described magnet steel is 15.3～15.5mm, and the thickness of described magnet steel is 1.35～1.45mm, and the length of side of described installation opening is 5.0～5.4mm
As preferably, the outer knuckle of described magnet steel is respectively arc chord angle transition.
Therefore, the Nd-Fe-B magnet steel for instrument that the utility model provides, compact conformation, improving product performance, increases the service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional structure schematic diagram of installation opening inwall in the utility model.
