Specific embodiment

Embodiment:

It is shown a kind of specific embodiment of fast accurate type weight detecting device of the utility model in conjunction with attached drawing, it is first First, the electronic balance 2 including workbench 1 and on the workbench 1, if being equipped in left-right direction on the electronic balance 2 The ladder-like fence piece 3 of parallel interval distribution is done, the distance between ladder-like fence piece 3 described in adjacent two panels is equal, specifically, The ladder-like fence piece 3 includes integrated molding and four highly different sheet bodies, between the two neighboring sheet body Difference in height is equal.

The front and rear sides of the electronic balance 2 are respectively equipped with front apron 4, rear baffle 5, the front apron 4 and rear baffle 5 it Between be equipped with five pieces of lifter plates 6 can moving vertically up and down, the thickness of the lifter plate 6 is less than in the ladder-like fence piece 3 most Low sheet body is the distance between to the electronic balance 2.

Sheet body on the lifter plate 6 corresponding to ladder-like 3 four different heights of fence piece is respectively provided with placement weight The station of code 15 can place four counterweights 15 on i.e. every piece of lifter plate 6, and be additionally provided on the lifter plate 6 and lower part Several ladder-like fence pieces 3 be staggered more rack stakes of setting, each rack stake can be respectively along corresponding two panels steplike-gate The non-interference up and down motion in gap between column piece 3.

Further, the workbench 1 is equipped with and 6 one-to-one five driving mechanisms of each lifter plate, the driving Mechanism includes the servo motor 8 of screw rod 7, the connection driving screw rod 7, and the screw rod 7 is equipped with can along its length up and down The nut 9 of movement simultaneously connects corresponding lifter plate 6 by the nut 9, as shown in Fig. 2, five servo motors 8 are by installation frame 10 are mounted on the bottom of the workbench 1.

Specifically, the servo motor 8 has power output shaft and wears workbench 1, institute by the power output shaft The one end for stating screw rod 7 is mounted on the rear baffle 5 by bearing block 11, the other end by shaft coupling 12 connects corresponding servo electricity The power output shaft of machine 8.

In addition, on the front apron 4 correspond to each lifter plate 6 be respectively equipped with the limit guide groove 13 playing the guiding role and by Lifter plate 6 is limited in the top of the electronic balance 2 by the limit guide groove 13, i.e., limits lifter plate 6 by limit guide groove 13 Minimum altitude and the minimum altitude be higher than electronic balance 2 height, so as to effectively avoid lifter plate 6 and electronic balance 2 contacts, influence the reading of electronic balance 2, guarantee the calibration accuracy of counterweight 15.

Secondly, described device further includes controller, is respectively arranged on each lifter plate 6 for measuring the ranging biography of adjustable height Sensor 14, the electronic balance 2, each distance measuring sensor 14 and each servo motor 8 are connected with the controller.

When the present embodiment specific works, operator all places counterweight 15 on 20 stations of five pieces of lifter plates 6, According to sequence from left to right, controller controls first piece of lifter plate 6 and moves, remaining four pieces of lifter plate 6 is in stationary state, Specifically, controller controls first servo electricity according to the detection data that the distance measuring sensor 14 on first piece of lifter plate 6 is fed back Machine 8 works, by driving the corresponding rotation of screw rod 7 and driving first piece of lifter plate 6 to move downward by corresponding nut 9 until being down to pair Stopping when answering the minimum point of limit guide groove 13, four counterweights 15 on first piece of lifter plate 6 can be with regular hour difference successively It is placed in the ladder-like fence piece 3 of electronic balance 2；Then controller controls second piece of lifter plate 6 and moves downward until being down to Stop when the minimum point of corresponding limit guide groove 13, likewise, four counterweights 15 on second piece of lifter plate 6 are poor with the regular hour It is successively placed in the ladder-like fence piece 3 of electronic balance 2, until 20 counterweights 15 on five pieces of lifter plates 6 are all placed It finishes.

In detection process, the meeting of electronic balance 2 is by initial reading (gross mass of i.e. each ladder-like fence piece 3) and every time Reading after placing a counterweight 15 is sent to controller, and the quality of each counterweight 15 is calculated by controller internal processes (such as: the reading that electronic balance 2 is shown after the quality of first counterweight 15 need to only place first counterweight 15 subtracts electricity The initial reading of sub- balance 2, electronic balance 2 is shown after the quality of second counterweight 15 need to only place second counterweight 15 Reading subtract the reading that electronic balance 2 is shown after first counterweight 15 is placed, and so on).

This device is able to pass through the controller the calibrating of the completion high-volume counterweight 15 of fast accurate in an automated manner, Without carrying repeatedly by manually or mechanically hand, while the phenomenon that 15 surface abrasion of counterweight is with scratching is avoided the occurrence of, greatly shortened Calibrating time guarantees that calibrating efficiency effectively improves while calibration accuracy.

Certainly the above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with this The people of technology can understand the content of the utility model and implement accordingly, and the protection model of the utility model can not be limited with this It encloses.Any modifications made in accordance with the spirit of the main technical solutions of the utility model should all cover the guarantor in the utility model Within the scope of shield.
