Abstract

According to the bolt clamping force sensor for bolt locking operation provided by the invention, when a spiral fastener is locked, a torsion rotating shaft in the clamping force sensor is driven to enable a spiral mechanism at one end of the torsion rotating shaft to generate axial force; a deformation sensing value caused by the extrusion force sensing module and a clamping force generated when a sleeve driven by the other end of the torsion rotating shaft locks a spiral fastener of a specific specification are verified by a standard axial force meter in advance to obtain a parameter relation between the deformation sensing value and the clamping force, and the parameter relation serves as a basis for calculating and controlling the clamping force in the locking process. The clamping force sensor of the spiral fastener can be applied to various industries. When the spiral fastener locking device is connected to various torsion tools in a sleeving mode to conduct locking operation on spiral fasteners, the spiral fasteners of specific specifications can be effectively sensed so as to control the precision of clamping force acting on the spiral fasteners, and therefore the quality of the spiral fastener is improved.

Description

technical field [0001] The invention relates to a bolt clamping force sensor for bolt locking operation, in particular to a bolt clamping force sensor applied in the process of locking a screw fastener, which can directly sense the clamping force acting on the screw fastener, and A device that can transmit sensing data. Background technique [0002] Tightening bolts with a torque wrench has been widely used in the assembly of various products. Applying torque is a means, but its purpose is to tighten the bolts. The best and most difficult is how to tighten each bolt to the same tightness, especially in high pressure vessels, engine cylinders or vacuum equipment. It is an important issue that the industry is concerned about, such as precise locking operation that requires control of the clamping force of the bolt, but it has always been difficult to achieve only by controlling the locking torque. [0003] During the tightening process of existing bolts, only 10% of the torq...
