Abstract

The invention relates to a calibration device for a three-dimensional force measuring platform, which aims at overcoming the defect that the current force calibration device cannot carry out simultaneous force calibration of three directions on a flat plate type three-dimensional force measuring platform and a convex plate type three-dimensional force measuring platform according to the using needs, and providing a device for carrying out comprehensive and simultaneous orthogonal calibration on the force measuring sensor of the three-dimensional force measuring platform. The device can calibrate the two kinds of three-dimensional force measuring platforms with different appearances. The device is composed of a weight tray assembly, a counter-force plate and spoke type pressure sensor assembly and a three-dimensional force measuring platform calibration device foundation platform assembly, wherein the weight tray assembly is put on the three-dimensional force measuring platform, the counter-force plate and spoke type pressure sensor assembly is connected with the three-dimensional force measuring platform and is fixed by a bolt, and the three-dimensional force measuring platform is connected with the three-dimensional force measuring platform calibration device foundation platform assembly and is fixed by the bolt. The weight tray assembly is composed of a channel steel welding frame and a leg cushion block, and the leg cushion block is connected with the channel steel welding frame through the bolt.

Description

technical field

[0001] The invention relates to a force calibration device, in particular to a three-dimensional force measuring platform calibration device. Background technique

[0002] The current force calibration device cannot perform force calibration in three directions on the three-dimensional force measuring platform according to the needs of use, which has certain limitations. The present invention just makes up for this defect, and is easy to use and has a simpler and more reasonable structure. Moreover, the present invention can gradually apply pressure, and the calibration effect is more accurate and reliable. Contents of the invention

[0003] The purpose of the present invention is to overcome the defect that the existing force calibration device cannot perform force calibration in three directions on the three-dimensional force measurement platform according to the use requirements, and provide a three-dimensional force measurement platform calibration devi...
