Description

Technical Field

[0001] The utility model relates to the technical field of Vicat instruments, in particular to an automatic measuring and recording Vicat instrument. Background Art

[0002] Vicat apparatus, also known as cement consistency meter or cement consistency setting time tester, is a testing instrument widely used in cement and concrete industries. Through specific operations and standards, Vicat apparatus can determine the amount of water required for cement paste to reach standard consistency. Vicat apparatus can also be used to determine the setting time of cement paste, including initial setting time and final setting time.

[0003] Manual Vicat instrument requires frequent intervention of inspectors, and cannot achieve assembly line inspection, resulting in low inspection efficiency. With the existing automatic measurement and recording Vicat instrument, inspectors can place multiple test molds on the table frame, and only need to ensure that these test molds are between the positioning ring and the retaining ring. There is no need to manually intervene in the relative position of the test needle and the test mold, which is more convenient; through program control of the equipment operation, the inspection of multiple test molds can be completed and the results can be directly fed back and displayed on the human-computer interaction screen, which is convenient for inspectors to record data and reduce the work tasks of inspectors. However, the automatic Vicat instrument is driven by a motor to rotate, and the test mold is inspected by an infrared sensor, so that the automatic Vicat instrument stops rotating at the test mold and performs inspection work. It is difficult to ensure that the test needle of the Vicat instrument is in the middle position of the test mold, which will affect the inspection results. For this reason, an automatic measurement and recording Vicat instrument is proposed for improvement. Utility Model Content

[0011] The above technical solution is adopted: the test table provides support for the upper structure, and a stabilizing seat is set at the bottom to improve its stability. The rotating seat provides an installation platform for the placement seat and can drive the placement seat to rotate. An outer gear ring is set on the outside of the rotating seat, and the outer gear ring can be driven by the driving gear to rotate, and then drive the rotating seat to rotate. The placement table serves as a placement platform for the test mold, which can drive the test mold to rotate and adjust the position of the test mold under the drive of the rotating seat.

[0020] 2. The automatic measuring and recording Vicat instrument, because the size of the driving gear is smaller than that of the outer gear ring, the driving gear cooperates with the outer gear ring to drive the test mold to rotate, which can greatly reduce the speed of the test mold and prevent cement from being thrown out of the test mold. An elastic pad is set in the placement groove to elastically support the test mold and ensure the stability of the test mold in the placement groove.
