Clamping apparatus for shaft of parallel-connection type six-dimension force sensor

Abstract

The invention discloses a clamp device for the shaft a parallel six-dimensional force sensor, belongs to the field of sensors and measurement control thereof, and in particular to fixation and partial load of a six-dimensional force sensor for detecting strained condition of the shaft of huge overloading operating equipment. The clamp device for the shaft of the parallel six-dimensional force sensor comprises an upper inner clamp body and an upper outer clamp body, a lower inner clamp body and a lower outer clamp body, an upper stay bolt and an upper lag bolt, a lower stay bolt and a lower lag bolt. The upper clamp bodies are arranged on the upper surface of a piezoelectric quartz force sensor, and rigidly connected with the piezoelectric quartz force sensor by 8 evenly distributed upper stay bolts and 8 evenly distributed upper lag bolts. The lower clamp bodies are arranged on the lower surface of the piezoelectric quartz force sensor, and rigidly connected with the piezoelectric quartz force sensor by 8 evenly distributed lower stay bolts and 8 evenly distributed lower lag bolts. The clamp has the advantages of simple structure, good performance and low cost, can keep rigid connection between the shaft and the sensor and have load sharing function, and can be used for fixing axle hole elements.

Description

technical field [0001] The invention belongs to the field of sensors and measurement and control thereof, and in particular relates to the fixing and load sharing of a six-dimensional force sensor for detecting the force state on the shaft of a giant heavy-duty operating equipment. Background technique [0002] Fastening fixture is an important part of accurate measurement data in the field of sensing, measurement and control, and its performance directly affects the accuracy of measurement results. Simple structure, high precision and high sensitivity are one direction of fixture development. For the real-time measurement of the six-dimensional force on the axis of giant heavy-duty operating equipment with piezoelectric quartz force sensors, the selection and use of fixtures are quite important. There are many ways to connect the shaft and the hole in the traditional fixture, one of which is to connect the shaft and the hole through a wedge-shaped direct expansion structur...

AI Technical Summary

Problems solved by technology

For a structure with variable aperture, the diameter of the hole needs to be changed within a certain range. For a piezoelectric quartz force sensor, the central aperture is constant. Moreover, this structure is relatively complicated and the contact area cannot be large enough.

Therefore, the traditional fixture is not suitable for fixing the piezoelectric quartz force sensor of the six-dimensional force measurement on the axis.
