Pasting auxiliary device based on strain test

Abstract

The invention discloses a pasting auxiliary device based on a strain test. The pasting auxiliary device comprises a measuring point area, and a strain gauge arranged on the measuring point area at a certain angle, and further comprises a heating pot for applying pressure to the strain gauge, and a temperature control system for controlling the temperature of the heating pot. The strain gauge is pasted onto the measuring point area through glue; the temperature control system comprises a temperature sensor, a temperature controller for controlling the temperature of a heating rod in the heatingpot, and a low-voltage power supply used for providing electrical energy for the temperature controller; the heating pot comprises an elastic shell, a pot plug ring connected with an opening of the elastic shell in a sleeving mode, and a pot plug axially connected with the pot plug ring in a matched mode through a thread; and the pot plug extends into the elastic shell and is arranged in a sealedmode. The solidifying time of the glue is shortened, the influences of the external low temperature on pasting are reduced, and the pasting efficiency is high.

Description

technical field [0001] The invention relates to the technical field of stress and strain testing, in particular to a patch auxiliary device based on strain testing. Background technique [0002] The fatigue life of the metal parts of the forklift directly affects the life cycle of the forklift and the safety of personnel, and the stress on these metal parts has a key impact on its fatigue life. The stress on the metal is equal to the strain multiplied by the elastic modulus of the material, and the strain is obtained through the strain test. The patch is an essential and important step in the strain test. The quality of the patch directly affects the accuracy of the strain test results. Spend. In the traditional strain test patch process, fingers need to press the strain gauge through the Teflon film to squeeze out the excess glue and air bubbles under the strain gauge. Wait for the glue to solidify, then release your fingers, pick up the film, and complete the patch. [...

AI Technical Summary

Problems solved by technology

[0003] However, the above traditional strain test patch has the following defects: if the ambient temperature is too low, the glue curing time will be longer, and the pressing time needs to be increased by more than 2 times, the patching efficiency is low, and long-term pressing will make the operator's fingers sore
