The present invention's one determines force compactor, is made up of base, push rod, Compress Spring, threaded, baffle plate, follower, gage, pointer, hexagon socket cap head screw and hexagon socket cap head screw.Pointer top is tapered needle, and bottom is thread spindle, and pointer and push rod termination are threaded connection formation STATEMENT OF FEDERALLY SPONSORED.Follower is connected with the rectangular opening place of gage in gage termination, in order to ensure the reliability connected, carries out spot welding reinforcing at connecting portion.Follower and gage form STATEMENT OF FEDERALLY SPONSORED; Threaded moves in the threaded hole of base, and threaded holds out against follower; Compress Spring is placed in the centre of push rod and follower, and lower and push rod and follower section fit tightly in working order for they; For preventing coming off of in inoperative push rod, by hexagon socket cap head screw, baffle plate is fixed on the leading section of base; During use, whole compactor is connected to required by (Fig. 1) on laminate body by hexagon socket cap head screw.

The Compress Spring that the present invention determines force compactor is high-precision spring, and the compression accuracy of spring is +/-10%.Do not contact by the relative distance of laminate body prior pointer and gage constant, when contact object after Compress Spring compression after, pointer can record numerical value on gage.

When the present invention determines force compactor operation, determining force compactor consistent with being pushed up product surface of contact normal, on inspection clamp, its theoretical normal can be shown.General survey clamp departs from wallboard profile 2 ?5mm, whether meets shape requirement by gauge inspection wallboard profile, when not afterburning, undesirable, can apply ≤ 45Nlocal pressure.For the ease of installing and using, determine force compactor deviation theory contact point 5 ?10mm.Knob thread pin, because push rod 2 termination does not stress, gage and Compress Spring are moved forward by follower, Compress Spring does not stress, omnidistance without compression, drive pointer movement in push rod moving process, the displacement of pointer movement is identical with the displacement of gage movement, its relative position is constant, and the scale of pointer on gage remains unchanged (Fig. 2).

The present invention determines force compactor push rod termination and is restricted, and when threaded rotation moves ahead, spring is compressed, and the amount of spring-compressed is reflected in the relative displacement of pointer 8 and gage, i.e. certain numeral on pointed scale mark.By the relevant position of pointer on scale band, namely obtain the dynamics (Fig. 3) of threaded knob.

Effect of the present invention:

(1) Hooke's law is passed through---after solid material is stressed, linear between the stress and strain in material, for Compress Spring, when there is elastic deformation in spring, the elastic force F of spring and elongation (or decrement) x of spring is directly proportional, i.e. F=kx.K is the elasticity coefficient of material, and it only determined by the character of material, has nothing to do with other factors.Negative sign represents that the elastic force that spring produces is contrary with the direction of its elongation (or compression).Being converted into displacement by determining power, intuitively, being convenient to observation;

(2) arranged by relative movement, be convenient to installing and using of compactor, and improve precision;

(3) be convenient to expansion, by added force sensor, proximity transducer, improve the efficiency of compactor.

Instant invention overcomes the defect of existing compactor, the fields such as aviation, automobile, packaging that can be applicable to have to applying power that the product of requirement holds out against, Fixture Design, have larger using value.
