Abstract
The invention relates to a looseness-preventing acceleration sensor magnetic suction base device. The looseness-preventing acceleration sensor magnetic suction base device comprises a metal outer shell, a permanent magnet fixed to the metal outer shell, a bolt and an elastic washer, wherein the bottom of the bolt is arranged on the metal outer shell, the head of the bolt penetrates through the metal outer shell to be connected with an acceleration sensor, and the elastic washer is arranged on the bolt in a sleeving mode. Compared with the prior art, the looseness-preventing acceleration sensor magnetic suction base device has the advantages that the vibration conduction effectiveness of a detected object is improved, and the measurement result accuracy of the acceleration sensor is guaranteed.
Description
Technical field
The present invention relates to a kind of acceleration transducer stationary installation, especially relate to a kind of anti-loose acceleration transducer magnetic absorbing seat device.
Background technology
At present, the common method of installing acceleration transducer has: bolt connects, cementing agent connects and magnet adsorption connects.Wherein, magnet adsorption connects easy to use.But magnet (magnetic absorbing seat) and acceleration transducer are bolted, this junction relies on the friction force of screw thread to fix, and is easily subject to testee vibration and throws off, causing measured value inaccurate.
Summary of the invention
Object of the present invention be exactly in order to overcome above-mentioned prior art exist defect and a kind of anti-loose acceleration transducer magnetic absorbing seat device is provided.
Object of the present invention can be achieved through the following technical solutions:
A kind of anti-loose acceleration transducer magnetic absorbing seat device, is characterized in that, comprise
Metal shell;
Permanent magnet, is fixed on metal shell;
Bolt, is located at bottom it on metal shell, and its head is connected with acceleration transducer through after metal shell;
Elastic washer, is set on bolt.
Also comprise the isolation pad be located between bolt and permanent magnet.
Described metal shell is provided with for the ferropectic groove of permanent magnetism and wears the through hole penetrated for bolt.
Described permanent magnet is fixed in the groove of metal shell by glue.
Described elastic washer is enclosed within bolt, and with metal shell compact siro spinning technology.
Compared with prior art, the present invention has the following advantages:
Improve the validity of testee conduct vibrations, ensure the measurement result accuracy of acceleration transducer, when this magnetic absorbing seat device is connected with acceleration transducer, along with the length of threaded engagement increases, bolt can force elastic washer to be out of shape, thus produce pressure to faying face, prevent relatively rotating of magnetic absorbing seat and acceleration transducer.
Accompanying drawing explanation
Fig. 1 is sectional view of the present invention;
Fig. 2 is duty sectional view of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As shown in Figure 1, a kind of anti-loose acceleration transducer magnetic absorbing seat device, comprises
Metal shell 5;
Permanent magnet 4, is fixed on metal shell 5;
Bolt 1, is located at bottom it on metal shell, and its head is connected with acceleration transducer through after metal shell 5;
Elastic washer 2, is set on bolt 1;
Isolation pad 3, is located between bolt 1 and permanent magnet 4.
Described metal shell 5 is provided with for the ferropectic groove of permanent magnetism and wears the screw hole penetrated for bolt.Described permanent magnet 4 is fixed in the groove of metal shell by glue.Described elastic washer 2 is enclosed within bolt 1, and with metal shell compact siro spinning technology.Isolation pad 3 act as isolation glue, prevents glue from bonding bolt.
As shown in Figure 2, acceleration transducer a and magnetic absorbing seat device b is fixed by bolt 1, to revolving acceleration transducer a and magnetic absorbing seat device b, along with bolt 1 and acceleration transducer a screwing length increase, elastic washer 2 on bolt is subject to bolt and metal shell 5 pressure produces deformation, upwards producing a pretightning force in bolt shaft, increase the friction of acceleration transducer faying face and magnetic absorbing seat, preventing the vibration measuring testee c from getting loose.
