Description

Technical Field

[0001] This utility model relates to the technical field of calibration equipment for metering belt scales, specifically a gripping device for calibration ball weights of metering belt scales. Background Technology

[0002] Measuring belt scales are widely used in industrial production for continuous material measurement. Their accuracy directly affects the quality control and cost accounting of the production process. To ensure the measurement accuracy of the measuring belt scale, it is necessary to calibrate it periodically using calibration balls. Currently, the calibration operation mainly relies on manual grasping of the calibration balls. Manual grasping is not only labor-intensive and inefficient, but it is also difficult to ensure that the position and force of each grasp are consistent, which can easily damage the calibration balls and affect the calibration accuracy. In order to improve this situation, it is of great practical significance to develop a grasping device for the calibration balls of the measuring belt scale.

[0003] A calibration ball weight gripping device for a metering belt scale, as described in reference announcement number CN203798444U, includes a first handle and a second handle. One end of the first handle is connected to a first clamping sleeve via a first crank, and the other end of the first handle is hinged to the second handle. The end of the second handle connected to the first handle is connected to a second clamping sleeve via a second crank. The concave surfaces of the first and second clamping sleeves are spherical and symmetrical. This device is simple to operate, provides a secure grip, and can quickly grip and place or remove spherical balls from the belt scale, avoiding the inefficiency and safety issues of manual handling, thus improving the calibration efficiency of the metering belt scale. Furthermore, it has a simple structure and is easy to use. However, as can be seen from the above, although this device can be applied well, it only has the function of gripping balls and it is not easy to adjust the gripping components to a specified height and position, making the device somewhat inconvenient to use and requiring further improvement.
