Outside acceleration sensor is fixedly mounted in the center counterbore of magnet slide block, in magnet slide block and magnetic support component The annular protrusion structure axial limiting that heart through hole is slidably matched and passes through magnet slide block;Magnet is placed in the inside of magnetic support component.
The magnetic support component is made up of magnetic support housing and end cap;
The preferred aluminium alloy of material of the magnetic support housing;Magnetic support housing is the cylindrical structure that one end open is closed in one end, Magnetic support enclosure interior is machined with magnet mounting hole and a central through hole vertically, the inner surface of central through hole and is machined with edge Circumferential annular groove;
The end cap is to be machined with a central through hole vertically, an end face of end cap on circular ring, end cap On be machined with two symmetrical bulge-structures;
End cap is fixedly connected with the open end of magnetic support housing, and the open end of magnetic support housing is closed;Magnet slide block passes through end The central through hole of lid, annular protrusion structure and the annular groove on magnetic support casing center through hole of magnet slide block are slidably matched;Magnetic Iron is placed in the magnet mounting hole of magnetic support housing, and is in contact with end cap one end away from bulge-structure.
The preferred ndfeb magnet of material of the magnet and magnet slide block.
Preferably one piece or two pieces of the magnet.
Beneficial effect
(1) compared to traditional acceleration transducer magnetic support, acceleration transducer magnetic support described in the utility model passes through Add a magnet slide block that can be moved up and down and the firm supporting mechanism of magnetic support bottom surface, magnet slide block and firm support The cooperation moved between mechanism, can make the firm absorption of the magnetic support on test surfaces of different shapes, improve magnetic support Applicability.
(2) acceleration transducer magnetic support described in the utility model have small volume, low manufacture cost, it is easy to use, be easy to Assembly and disassembly and the advantages of be easy to carry.
Brief description of the drawings
