Problems solved by technology

However, limited by the contradiction between large strain and high structural strength, the strain-type force helix measurement sensor provided in the existing literature reports cannot achieve accurate measurement of micro-force helix in engineering, and it is urgent to develop a micro-force helix measurement system
[0005] At present, there is no literature report on this kind of high-precision micro-force screw measurement system at home and abroad.

Abstract

The invention discloses a micro-force spiral measuring device and system; the device comprises a handle, a strain type torque measuring sensor, a piezoelectric force cell sensor, and a tool head; thebottom of the handle is connected with the strain type torque measuring sensor; the bottom of the strain type torque measuring sensor is connected with the top of the piezoelectric force cell sensor;the tool head is fixed on the piezoelectric force cell sensor via a jackscrew. The device can measure a micro-force spiral, can ensure a high intensity, is high in measuring resolution, and good in dynamic performance.

Description

technical field [0001] The invention relates to the micro-force spiral measurement technology in engineering. In particular, it relates to a micro-force screw measuring device and system. Background technique [0002] Force helix is ​​the most general case of simplification of any force system in space. In engineering technology, when a screwdriver screws a screw and a drill bit drills a hole, the force on the workpiece is the force helix. Force helix, also known as "couple force group", is a combination of a force and a torque parallel to it in a direction, which requires that the force helix measurement sensor must have the ability to accurately measure both the force component and the torque component in the force helix. The force screw measuring sensor provided in the existing literature reports is a strain sensor, wherein the force sensor and the torque sensor are respectively a straight beam strain sensor and a circular shaft or cylinder strain sensor. The straight b...
