Problems solved by technology

However, the calibration equipment developed by the absolute coordinate method also has its own application limitations. These equipment are generally expensive and require a long time for calibration, which is not conducive to the industrial promotion of mass-produced sensors, and is not suitable for the calibration of sensors in mass production.

Embodiment Construction

[0024] The present invention will be further described below with examples in conjunction with the accompanying drawings.

[0025] to combine figure 1 , the present invention mainly is made up of fixed platform mechanism 1, drive mechanism 2, connecting rod mechanism 3, universal hinge mechanism 4, moving platform mechanism 5. The present invention adopts a typical Stewart type parallel structure. The mechanism has two platforms, upper and lower, which are connected sequentially through six connecting rod mechanisms driven by servo motors. The upper ends of the six connecting rod mechanisms are hinged with the moving platform through universal hinges, while the lower ends are hinged with the fixed platform, forming six degrees of freedom. parallel mechanism. The six linkage mechanisms are divided into three groups, and two adjacent linkage mechanisms form a group, which is arranged in a figure of eight. The six positions hinged with the fixed platform are distributed on the...

Abstract

The invention provides a multi-dimensional force sensor calibration device with controllable poses. The multi-dimensional force sensor calibration device comprises a fixing platform, drive mechanisms, connecting rod mechanisms and a moving platform. The upper ends of the drive mechanisms and the lower ends of the connecting rod mechanisms are connected to form drive connecting rod mechanisms. The upper ends of the six drive connecting rod mechanisms are hinged to the moving platform through universal hinges, and the lower ends of the six drive connecting rod mechanisms are hinged to a fixed platform to form a six-freedom-degree parallel mechanism. The six drive connecting rod mechanisms are divided into three groups. Every two adjacent drive connecting rod mechanisms form one group and are arranged in the mode shaped like a Chinese character 'ba'. The poses of a calibration platform can be controlled and changed, and the calibration device has the function of calibrating a sensor dynamically and statically, and is complete in function, convenient to operate, high in calibration precision and capable of being well applied to practical engineering.

Description

technical field [0001] The invention relates to a calibration device for a multi-dimensional force sensor. Background technique [0002] Sensors are the key basic components and cutting-edge tools of information technology and information systems, and their production level directly affects the technical level of detection control systems and information systems. Since a large number of sensors are produced every year, a large number of sensor calibration work follows. The calibration accuracy of the sensor directly affects the measurement accuracy of the sensor when it is used in the future. At present, domestic research on the calibration of force sensors is mainly focused on static calibration, and dynamic calibration of sensors is generally measured by means of experiments or by absolute coordinates. However, the calibration equipment developed by the absolute coordinate method also has its own application limitations. These equipment are generally expensive and requir...
