Abstract
The utility model discloses a double inclined surfaces spring scale, which is characterized in that a three-point form load bearing frame construction is composed of two supporting points on a positioning frame connected with a shaft and one supporting point on the other positioning frame, clearance is arranged between the positioning frames and the load bearing frame, the shaft passes through the load bearing frame, and blocks are arranged at the tail end of the cross shaft of the two supporting points. Because the utility model adopts the three-point form load bearing frame construction, spacing of the twoends of one shaft is arranged in the transverse direction, and the contact between the shaft and the blocks is point-contact. The utility model has the advantages of small friction, stable measuring performance, long service life, and convenient installation and adjustment, and is the ideal double inclined surfaces spring scale.
Description
The utility model belongs to the technical field of measurement instrument, specifically relates to the load-carrying members in the double inclined plane spring scale scale.
Load-carrying members in the existing double inclined plane spring scale scale mostly adopt, locating rack by two parallelogram, forming stress point is the four-point framed structure of a vertical plane, as Fig. 1, shown in Figure 2, the four-point framework 15 of load-bearing in loading process, by two axles 7 is fulcrum, locating rack 18 rotates around fulcrum together with axle, (in actual weighing process, often there is the side force of removing vertical direction) when in loading process, side force occurring, because the restriction of spacing collar 20, lean on arm-tie projection and supporting frame 15 on the locating rack of fixing with axle 18 to touch support, avoiding deflection, but, cause the metering performance instability easily because of mutual surface of contact makes friction force also bigger greatly, precision is low, serviceable life is short, because the locating rack structure of two parallelogram is arranged, needs two parallelogram all to align when Installation and Debugging in addition, but it is, therefore pretty troublesome time-consuming when debugging because various factors is not easy alignment.
The purpose of this utility model is to provide a kind of Installation and Debugging of being convenient to, the double inclined plane spring scale scale of good stability.
The utility model is realized by following technical method, it mainly comprises base, is contained in double inclined plane scale, pointer and base-mounted supporting frame, locating rack, metering spring and mechanical drive dress on the outer cover, it is characterized in that: two fulcrums on the locating rack that links to each other with axle and a fulcrum of another locating rack are formed the supporting frame structure of bikini, leave certain clearance between locating rack and supporting frame, axle passes supporting frame, is provided with link stopper at the tail end of two fulcrum transverse axis.
The utility model is owing to adopt the load-carrying members of bikini, spacing at two ends that laterally have only an axle, and be provided with link stopper at the tail end of axle and can form a contact, reduced friction force greatly, also reduced the influence of supporting frame stress deformation, improved the stability and the precision of Weighing, when Installation and Debugging, do not needed all upper and lower alignment of the positioning framework of two parallelogram, improve work efficiency, met the quality standard of weighing apparatus after tested.
Fig. 1 is existing four-point load-carrying members synoptic diagram.
Fig. 2 is the H point enlarged diagram among Fig. 1.
Fig. 3 is a structural representation of the present utility model.
Fig. 4 is an A-A cut-open view among Fig. 3.
Fig. 5 is 1 enlarged diagram among Fig. 4.
The utility model will be further described below in conjunction with drawings and Examples, this scale mainly comprises base 1, be contained in the double inclined plane scale 2 on the outer cover 19, pointer 3 and supporting frame 15, mainly by arm- tie 8,16 and axle 7 form parallelogram locating racks, one end of metering spring 14 links to each other with zero-bit levelling knob 11, the other end links to each other with supporting frame 15, this framework 15 is by two fulcrums on the locating rack that links to each other with axle 7, and the bikini supporting frame structure of a fulcrum of another locating rack composition, 15 of arm-tie 8 in the locating rack and supporting frames leave certain clearance, tail end at the transverse axis 7 that passes heavy support frame frame 15 is provided with link stopper 17, supporting frame 15 can be a quadrilateral, rectangle, or other shape, two fulcrum operated by rotary motion on the locating rack are on two relative limits of framework, one fulcrum of another locating rack can be arranged on axle 7 framework far away, the present embodiment framework adopts rectangle, two fulcrums on the locating rack are arranged on two long limits of rectangle, fulcrum on another locating rack is arranged on the framework of axle close minor face far away, tooth bar 5 and pointer gear 4 engagements, and link to each other with tooth bar drive link 6, small rod 12 also is movable the connection with tooth bar drive link 6, the tail end of axle 7 has an outstanding tip, at axle 7 and arm-tie 8 is that point contacts when rotation touches link stopper 17 synchronously, with the power of reducing friction, link stopper 17 should be through bakingout process to strengthen its hardness, increase the service life, for the then degree that strengthens axle can be provided with fixed cover 13 on the arm-tie 8 of locating rack, also can consider to have on the link stopper an outstanding tip, axle is a tack, still holding point contact when touching, the upper end of scale is pan of a steelyard holder 9 and pan of a steelyard 10.When weighing, the object of placing on the scale pan 10 produces downward weight and is being supported by scale pan holder 9, and be connected to an end and the bikini supporting frame 15 of metering spring 14, therefore framework also produces downward weight, by parallel arm- tie 8,16 and the axle 7 parallelogram locating rack structures of being formed, because framework is to bottom offset and have one group of arm-tie to do the circular arc rotation, in rotation, make supporting-point with a rotation axis, do around the rotation of axle, because lateral thrust (in the weighing process, forming naturally), it is limited and with a contact that the axial displacement that is produced has pivot 7 to touch link stopper 17, and because of adopting the bikini load-carrying members, laterally have only two ends of a transverse axis spacing, it also all is a contact, friction force is little, be not subjected to the influence of framework 15 stress deformation factors, in addition since the bikini supporting frame in the transmission process of parallelogram locating rack, supporting the load of weighing by the metering spring other end, make small rod 12 and tooth bar drive link 6 remove to drive tooth bar 5 do movement in a curve, and the engagement by tooth bar and pointer gear 4, deflection angle, the also synchronous deflection angles of finger assorted 3 are housed, so most advanced and sophisticated indicated inclined-plane scale 2 places of pointer are gravimetric value in the outer end of the same axis that refers to assorted gear.
