Description

Technical Field

[0001] The utility model relates to the technical field of weight verification, in particular to an automatic verification device for F2 weight verification. Background Art

[0002] In applications such as precision machining and precision experiments, precision balance weights are often required to improve accuracy. To maintain high precision, the weights in use must be calibrated. Existing calibration methods primarily rely on manual methods, comparing a standard weight with the weight to be measured, recording the data, determining the error, and performing the calibration. This method is quite inconvenient and inefficient.

[0003] The F2 automatic weight verification device has a reference patent number of CN112240800A. When the automatic weight verification device is in use, the first manipulator places the standard weight on the comparator, records the data, and then moves it back. The second manipulator places the corresponding weight to be tested on the first or second weight trolley to be tested on the comparator, records the data, and then moves it back. While the first manipulator moves back, the second manipulator can carry the weight to be tested toward the comparator. Compared with manual verification, this can greatly save time and improve efficiency.

[0004] However, the above automatic weight verification device, although performing comparative detection on the weights to be detected, does not have the function of automatically collecting the detected weights separately, thereby reducing the collection efficiency.

[0005] Therefore, we propose an automatic verification device for F2 weight verification. Utility Model Content

A second motor 15 is fixedly installed on the left surface of the bracket 12, a rotating rod 16 is rotatably provided between the left and right inner walls of the bracket 12, a gear 17 is fixedly connected to the outer surface of the rotating rod 16, an arc plate 18 is fixedly connected to the lower surface of the comparator 13, and a tooth groove 19 is provided on the outer surface of the arc plate 18.

[0028] Specifically, through the cooperation among the frame 1, the first telescopic cylinder 2, the pipeline 3, the first motor 4, the threaded rod 5, the threaded pipe rack 6, the first notch 7, the second telescopic cylinder 8, the manipulator 9, the standard weight rack 10, the weight rack to be tested 11, the bracket 12, the comparator 13, the track 14, the second motor 15, the rotating rod 16, the gear 17, the arc plate 18, and the tooth groove 19, the qualified weights on the comparator 13 are automatically tilted to the right for collection, and the unqualified weights are automatically tilted to the left for recovery, and they are collected and processed separately, thereby improving the classification efficiency.

[0029] In this embodiment: the output end of the first motor 4 is fixedly connected to the threaded rod 5 on the corresponding side, the threaded pipe rack 6 and the first slot 7 are slidingly arranged correspondingly, and the first motor 4, the first telescopic cylinder 2, the second telescopic cylinder 8 and the second motor 15 are electrically connected.

[0030] Specifically, the first motor 4, the first telescopic cylinder 2, the second telescopic cylinder 8 and the second motor 15 are existing structures, and the control circuit can be implemented by simple programming by technicians in this field. It is common knowledge in this field and is only used without modification. Therefore, the control method and circuit connection will not be described in detail.

[0031] In this embodiment: the manipulator 9 is arranged correspondingly to the weights on the standard weight rack 10 and the weight rack to be tested 11, the output end of the first telescopic cylinder 2 is fixedly connected to the front surface of the corresponding side pipe 3, the output end of the second motor 15 is fixedly connected to the left surface of the rotating rod 16, and the gear 17 is arranged in corresponding meshing with the tooth groove 19.

[0033] Working principle: When calibrating the F2 weights, the bracket 12 at the bottom of the frame 1 and the standard weight racks 10 and the weight racks 11 to be tested on both sides are placed stably, and then the first telescopic cylinder 2 is used to push the pipe 3 to the specified position, and then the first motor 4 on the pipe 3 drives the threaded rod 5 to rotate forward and reverse as needed, and the threaded pipe rack 6 can be moved left and right on the pipe 3 in conjunction with the first slot 7, thereby driving the manipulator 9 on the second telescopic cylinder 8 at the bottom to move to the specified weight.

When the weight on the comparator 13 fails the inspection, the second motor 15 drives the rotating rod 16 and the gear 17 to rotate forward, thereby cooperating with the tooth groove 19 on the arc plate 18 to rotate the comparator 13 to the left and tilt, so that the unqualified weight can be moved to the rear side and out of the comparator 13 for processing.

[0039] Specifically, the push plate 28 is received by the second slot 27 .
