A four-corner error calibration device for a load cell

Abstract

The invention discloses a calibration device for error of four corners of a weighing sensor. The calibration device comprises a rack. The internal part of the rack is provided with a platform A and a platform B which are arranged from the top to the bottom in turn and mutually parallel. The two ends of the platform A are respectively provided with a radial guide rail A along a horizontal direction. The radial guide rail A is provided with a movement mechanism which is used for driving a weight set supporting base to move. The upper end of the weight set supporting base is provided with a first cylinder which moves along a vertical direction. A support used for driving a weight rod to move is arranged below the first cylinder. The support is arranged in the weight set supporting base. The lower end of the weight rod is provided with a weight set. A horizontal pallet is arranged below the weight set. A weighing sensor clamp is connected at the bottom part of the horizontal pallet. The weighing sensor clamp is driven by a second cylinder. A pallet lifting mechanism is arranged below the horizontal pallet. The pallet lifting mechanism and the weighing sensor clamp are arranged on the platform B. The problems of the existing calibration devices for error of the weighing sensor that loading stability is poor and test precision and efficiency are low in the loading process can be solved.

Description

technical field [0001] The invention belongs to the technical field of load cell detection equipment, and relates to a four-corner error calibration device for a load cell. Background technique [0002] At present, the four-corner error calibration device of the load cell has high labor intensity, low test efficiency, and poor test accuracy in the process of measuring the load cell, because most of them now use weight loading to load the sensor. During the loading process There is a certain degree of shaking in the middle weight, and the stability cannot be well guaranteed. In addition, the existing load cell detection equipment also has problems such as high production cost and inconvenient operation for workers. Contents of the invention [0003] The object of the present invention is to provide a four-corner error calibration device of a load cell, which solves the problems of poor loading stability, low test accuracy and efficiency, and high labor intensity of the exis...
