Abstract
The utility model relates to sensor fields, disclose a kind of acceleration transducer, including shell, spring beam, metal strain plate, mass block, lead, cover board, spring beam is set to enclosure interior and its both ends is fixed with shell, hull outside setting installation cover board, metal strain plate connecting lead wire, lead is drawn from the housing side of sensor, spring beam is tubulose, metal strain plate is arranged in its lumen wall, and mass block is fixed at the middle position of spring beam length direction and the mass block only has contact surface with spring beam.Mass block is arranged in tubular elastomeric beam middle position the utility model and mass block only has contact surface with spring beam, so that the deformation of spring beam is had symmetry and reduces tangential stress, answers piece to play sensitivity conducive to the metal being attached on spring beam；Since metal strain plate is arranged in spring beam lumen, is more conducive in the environment of dust, electromagnetic field dust-proof and reduces environment electromagnetics interference.
Description
Technical field
The utility model and sensor field, specially a kind of acceleration transducer.
Background technique
In coal industry, its acceleration of vibration measurement is sieved to coal separation to monitor it and screen operating condition, such acceleration passes
Sensor generally uses piezoelectric acceleration sensor, silicon piezoresistive acceleration sensor etc..Also it makes improvements using metal sense
Acceleration sensor of the piece as sensing element is answered, one end of spring beam, and gravity is generally arranged in mass block by this kind of sensor
The mounting means of block makes spring beam there are more tangential stress, is unfavorable for being attached to the metal on spring beam and piece is answered to play induction
Performance.
Utility model content
The purpose of this utility model is to provide a kind of acceleration transducer, the technology for solving to mention in technical background is asked
Topic.
To achieve the above object, the utility model provides a kind of acceleration transducer, including shell, spring beam, metal are answered
Become piece, mass block, lead, cover board, the spring beam is set to enclosure interior and its both ends is fixed with shell, and hull outside is set
Installation cover board, metal strain plate connecting lead wire are set, lead is drawn from the housing side of sensor, and spring beam is tubulose, lumen
Inner wall be arranged metal strain plate, mass block be fixed at the middle position of spring beam length direction and the mass block only with bullet
Property beam has contact surface.
Preferably, the spring beam is square tube.
Preferably, the spring beam is round tube.
Further to improve, mass block is set in the middle position of spring beam length direction and fixation.
Further to improve, mass block is fixed with spring beam spline.
Further to improve, spring beam both ends are fixed with case weld.
It is further to improve, mass block central symmetry and symmetrical above and below in shape, quality.
Further to improve, spring beam is made of 17-4PH stainless steel.
The utility model provides a kind of acceleration transducer, have it is following the utility model has the advantages that
By by mass block be arranged tubular elastomeric beam length direction middle position and the mass block only have with spring beam
Metal strain plate is arranged in contact surface, spring beam lumen wall, so that the deformation of spring beam is had symmetry and reduces tangential stress, benefit
Piece is answered to play sensitivity in the metal being attached on spring beam.
Since metal strain plate is arranged in spring beam lumen, be more conducive in the environment of dust, electromagnetic field dust-proof
It is interfered with environment electromagnetics are reduced.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
In figure: 1 shell, 2 spring beams, 3 metal strain plates, 4 mass blocks, 5 leads, 6 cover boards.
Specific embodiment
As shown, a kind of acceleration transducer, including shell 1, spring beam 2, metal strain plate 3, mass block 4, lead
5, cover board 6, the spring beam 2 is set to 1 inside of shell and its both ends is welded and fixed with shell 1, and installation is arranged outside shell 1
Cover board 6,3 connecting lead wire 5 of metal strain plate, lead 5 are drawn from 1 side of shell of sensor, and spring beam 2 is square tube, can also be with
For round tube, metal strain plate 3 is arranged in lumen wall, and metal strain plate 3 uses fine enamelled wire welding lead 5, metal strain plate 3
Upper and lower four connect into electric bridge, constitute test circuit；Interposition of the fixed sheathed setting of mass block 4 in 2 length direction of spring beam
It sets and the mass block 4 only has contact surface with spring beam 2, mass block 4 can also be fixed with spring beam 2 with spline, the mass block 4
The central symmetry and symmetrical above and below in shape, quality；The spring beam is made of 17-4PH stainless steel.Cover board 6 is provided with peace
Dress hole is easily installed on the vibrating.
