[0024] Specifically, by changing the position of the U-shaped clamping plate 15, the weight 18 is automatically transported to the surface of the weighing area of ​​the measuring instrument, which can save manpower and prevent damage to the weight.

[0026] Among them: the axial cross-section of the weight handle 19 is I-shaped, the width of the limiting groove 17 is greater than the outer diameter of the middle part of the weight handle 19, and the width of the limiting groove 17 is smaller than the outer diameter of both ends of the weight handle 19, the limiting groove 17 can pass through the middle part of the weight handle 19, and lift the weight handle 19 when the U-shaped clamping plate 15 rises.

[0028] Working principle: The utility model is a weight clamping device for measuring instrument calibration. When in use, the switch of the first motor 5 is turned on to drive the gear 6 to rotate, and the gear 6 drives the rotating plate 3 to rotate through the teeth 4, thereby driving the weight limit sleeve 7 with the weight 18 inside to be transported to the corresponding position below the L-shaped mounting plate 8, and then the switch of the second motor 11 is turned on to drive the threaded rod 12 to rotate, thereby driving the slider 10 to move horizontally, and the slider 10 drives the U-shaped clamping plate 15 to move horizontally through the electric push rod 13 and the connecting plate 14, so that the U-shaped The card plate 15 moves to the outside of the weight handle 19, and the part with a small outer diameter in the middle of the weight handle 19 passes through the inner side of the limiting groove 17. Then, the electric push rod 13 is controlled to contract, driving the connecting plate 14 and the U-shaped card plate 15 to move upward.

When the weight is transported to the weighing area of ​​the measuring instrument, the electric push rod 13 is controlled to move downward, so that the U-shaped card plate 15 drives the weight 18 to move downward until it is placed on the surface of the weighing area. Then, the U-shaped card plate 15 is controlled to move horizontally, so that the weight handle 19 is disengaged from the inner side of the limiting groove 17. After the U-shaped card plate 15 is controlled to reset upward, the U-shaped card plate 15 is controlled to reset horizontally, and the rotating plate 3 is controlled to rotate, so that another weight limit sleeve 7 equipped with the weight 18 is located below the L-shaped mounting plate 8, which is convenient for subsequent weight clamping and transportation work.
