Abstract

The invention discloses a clamping force measuring sensor which comprises a stress supporting plate and a pair of force transmission levers symmetrically hinged to the stress supporting plate. A pair of mounting bases is arranged between the pair of force transfer levers; a spoke type elastic sensitive element is arranged between the two mounting bases and is used for receiving the clamping force transmitted by the force transmission levers and the mounting bases; a resistance strain gauge is pasted on the spoke type elastic sensitive element, and the resistance strain gauge converts the received clamping force into a voltage signal through a bridge measuring circuit. The clamping force sensor can be used as a universal clamping force measuring device, is compact in structure and proper in size, can be conveniently installed on handheld equipment to measure the measured clamping force, is high in sensitivity, can be used for measuring the clamping force and can also be used for automatic assembly, detection of medical equipment and measurement and test systems in the robot field.

Description

technical field [0001] The present invention relates to the technical field of sensors, in particular to a clamping force measurement sensor. Background technique [0002] Nowadays, human society has entered the information age. All aspects of industrial and agricultural production, transportation, logistics, social services, etc. need to obtain accurate and useful information from time to time. The acquisition of this information depends on the help of sensors. [0003] Countries and regions with a higher degree of informatization and automation have a greater demand for sensors and higher dependence on them. Since the 1980s, sensor technology has been researched as a key development technology by many developed and developing countries in the world. Sensor detection technology is the basis and premise of automation and informatization. It has a wide range of applications in the fields of resource detection, environmental monitoring, medical diagnosis, household appliances...
