The present invention is set to further: described fixed mount comprises base plate, is vertically installed in set collar and the spacing ring of base plate; Described electromagnet is fixed on set collar, and described counterweight cover loads spacing ring.
The present invention is set to further: the top of described base plate is provided with the fixed orifice hanging and connect.
The present invention is set to further: described base plate is provided with lightening hole.
The present invention is set to further: described set collar is one, and described spacing ring is two, is followed successively by the first spacing ring and the second spacing ring from top to bottom; The bottom of described electromagnet and the top of counterweight are distributed between set collar and the first spacing ring, and the second spacing ring is extended in the bottom of described counterweight.
The present invention is set to further: the top of described electromagnet is set with spring.
The present invention is set to further: described electromagnet is by nut lock in set collar, and described nut lock is in the end face of set collar.
Compared with prior art, the beneficial effect that the present invention has is:
By the setting of fixed mount and measuring head assembly, wherein measuring head assembly comprises the connected electromagnet of bridging type and counterweight from top to bottom, adopt the mode of counterweight freely falling body key tap can realize the test of sensitive performance, adopt the mode of electromagnetism conducting impact button can realize the test of electrical functionality, measuring head Components integration degree is high, automaticity is high, module shares, and significantly saves cost, and tests precise and high efficiency; The shortcoming that traditional component testing complex structure is not easy to safeguard can be overcome, easy damage tolerant, thus the replacement cost significantly saving testing apparatus.
Foregoing is only the general introduction of technical solution of the present invention, and in order to clearer understanding technological means of the present invention, below in conjunction with accompanying drawing, the invention will be further described.
