Abstract
The utility model discloses a non-weight verification device of weighing instrument, belonging to a verification tool field of weighing instrument, which is composed of a sensor, a digital display meter, a loading mechanism and a connection part. The loading mechanism will perform the loading and unloading of the to-be-verified weighing instrument, the digital display instrument of the verification device and the to-be-verified weighing instrument respectively displays the size of loading and unloading force and then performs contrast. The utility model has the advantages of light weight, high precision, strong practicality, wide application, saving time and force when verifying the weighing instrument. The utility model is used for the verification of various weighing instrument.
Description
The utility model relates to weighing apparatus verification apparatus field.
For the verification of most of weighing apparatus, required big quality counterweight is too many, and it is very inconvenient to operate, and operating cost is too high, and method of substitution only is a kind of method that adopts when the counterweight quantity not sufficient, has the existing problem of big quality counterweight equally.The non-counterweight verification of weighing apparatus is comparatively active at present field, among now developing rapidly, the precision of proving ring is too low, and the non-counterweight verification of sensor and digital indicator is current developing direction, discloses a kind of adjustable counterweight (the non-counterweight calibration equipment of weighing apparatus) in Chinese patent CN2142566Y.This device is owing to from great, need huge solid bow type support across scale body table top, and high material consumption is installed inconvenience, is difficult for promoting.
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of structure simpler, and volume is little, and installation requirement is low, and is easy to carry, saves time, laborsaving, economizes the high precision weighing apparatus tester of material, and the verification scope contains various weighing apparatus.
The purpose of this utility model is achieved in that the non-counterweight calibration equipment of a kind of weighing apparatus, form by loading mechanism, sensor by calibration equipment and known digital indicator and web member, loading mechanism is an automatic aligning spiral loading mechanism, and this spiral loading mechanism is a helical worm gear worm screw thrust bearing assembly.The helical worm gear worm screw of assembling is fixed in the casing by up-thrust bearing and lower thrust-bearing and by stifle and saturating lid, and saturating lid is a sphere with the contacted surface of packing ring, and forming the ballstone mat structure can automatic aligning.In order to reduce the error that non axial loading is introduced, improve precision, stifle and saturating lid inboard have groove, and some steel balls distribute in the groove.The rotation of handle drives worm screw, the worm drive worm gear rotation of rotating, the worm gear of rotation moves up and down screw rod, the sensor of calibration equipment and by the sensor of verification weighing apparatus simultaneously by loading, known digital indicator is according to showing calibration equipment respectively from the sensor of calibration equipment with by the signal of the sensor of verification weighing apparatus and by the loading force of verification weighing apparatus, operating personnel compare according to calibration equipment with by the known digital indicator displayed value of verification weighing apparatus, reach the purpose of verification weighing apparatus.
Driving force is little when the utlity model has verification, in light weight, precision is high, practical, use widely, save time during the big-and-middle-sized weighing apparatus of verification, advantage such as laborsaving.
Description of drawings
Fig. 1 is the utility model loading mechanism structure synoptic diagram.
Fig. 2 is the utility model user mode synoptic diagram.
Set forth embodiment of the present utility model below in conjunction with accompanying drawing:
During use, earlier the loading mechanism 17 of verification weighing apparatus press figure one installation, wherein worm screw 2 is fixed on the casing 10 by means of fixedly lower thrust-bearing 8, up-thrust bearing 9 and the bearing cap 1 of worm screw, and screw rod 4 is adjusted to suitable position.Stifle 11 and saturating lid 5 inboards have groove, and some steel balls distribute in the groove.The loading mechanism 17 that adjusts is installed on the weighing apparatus table top 12 to be verified, after the sensor 16 of calibration equipment is connected with loading mechanism 17 and weighing apparatus basis 13 with web member 14 and adjusts to the appropriate location, operating personnel pull handle 18, the handle 18 that rotates drives worm screw 2 rotations, the worm screw 2 of rotating is by means of the fixing lower thrust-bearing 8 of worm screw, up-thrust bearing 9 and bearing cap 1, drive worm gear 3 rotations, the worm gear 3 of rotation moves up and down screw rod 4, be connected the sensor 16 of the calibration equipment in the loading mechanism 17 and by the sensor 15 of verification weighing apparatus (sensor in especially corresponding corner) simultaneously by loading, known digital indicator is according to showing calibration equipment respectively from the sensor 16 of calibration equipment with by the signal of the sensor 15 of verification weighing apparatus and by the loading force of verification weighing apparatus, operating personnel compare according to calibration equipment with by the known digital indicator displayed value of verification weighing apparatus, reach the purpose of verification weighing apparatus.
