A strain gauge sticking mechanism

Abstract

The invention relates to a strain gauge pasting mechanism, in particular to a strain gauge pasting mechanism which can achieve automatic pasting of hole internal strain gauges. The strain gauge pasting mechanism solves the problems that due to the fact that common elastomer hole internal strain gauge pasting is completed mainly through manual work, accuracy and quality are low. According to the technical scheme, the strain gauge pasting mechanism is novel and mainly comprises a servo motor, a linear guide rail, a lead screw, a slider, an F-shaped motion base, an overturn air cylinder, pneumatic claws, pasting heads, a telescopic air cylinder, a tool rest and a blade. The linear motion combination of the servo motor, the lead screw and the linear guide rail is adopted, and therefore accuracy control over strain gauge hole internal pasting depth is achieved. Vertical opening-and-closing motion is achieved through the two arc-shaped pasting heads, and therefore strain gauges can be firmly pasted in elastomer holes. Two strain gauges can be pasted in the holes at a time through 180-degree rotation of the overturn air cylinder. The strain gauge pasting mechanism achieves automatic pasting of the hole internal strain gauges, greatly improves accuracy, and improves quality.

Description

technical field [0001] The invention relates to a strain gauge pasting mechanism, in particular to an automatic pasting mechanism for strain gauges in elastic body holes. Background technique [0002] In order to accurately measure the deformation of the elastic body, a common method is to paste a strain gauge on the surface of the elastic body, and indirectly measure the deformation of the elastic body by measuring the deformation of the strain gauge. At present, the automatic bonding of strain gauges to elastic bodies is mainly carried out when the surface of the elastic body is flat, while the bonding of strain gauges in the holes of general elastic bodies is mainly done manually. The position accuracy of manual pasting is low, the quality is poor, and the strain gauge cannot be pasted accurately in the required position in the hole of the elastic body.
