Abstract

The invention discloses a resistance strain gauge pasting device and an operation method thereof. The device comprises a housing, a replaceable positioning pedestal, a strain gauge adsorption device and an operation device. The replaceable positioning pedestal is inserted into a lower end opening of the housing, and is connected with the housing through a countersink blot. The operation device comprises a connection rod and a slide button which are fixedly connected. The slide button is arranged outside the housing. A spacing pin is arranged between the slide button and the housing. The strain gauge adsorption device comprises a cylinder, a piston and a strain gauge pedestal which are arranged in the housing. The resistance strain gauge pasting device is convenient to operate and is suitable for various types of resistance strain gauges.

Description

technical field [0001] The invention belongs to the technical field of instruments and meters in material science and mechanical manufacturing technology, and specifically refers to an auxiliary resistance strain gauge sticking device and a working method thereof. Background technique [0002] The resistance strain gauge is a device for measuring strain composed of a sensitive grid and the like. Resistance strain gauges come in various shapes and are widely used in various mechanical tests. Its working principle is that when a conductor or semiconductor is mechanically deformed under the action of an external force, its resistance value will change accordingly. This phenomenon is called "strain effect". When in use, it is necessary to paste the resistance strain gauge on the measuring point of the component. After the component is stressed, the resistance of the resistance strain gauge changes due to the strain of the measuring point. Then the resistance value of the resist...
