Strain gauge automatic welding and pasting device

Abstract

The invention belongs to the field of engineering tests, and in particular relates to a strain gauge automatic welding and pasting device. The strain gauge automatic welding and pasting device comprises a gun-shaped main body, wherein the gun-shaped main body comprises a gun barrel, a handle is arranged under the rear end of the gun barrel, and a trigger is arranged at a joint of the front side top part of the handle and the gun barrel; a smoothbore is arranged inside the gun barrel, the smoothbore extends from the front end to the rear end of the gun barrel but does not penetrate the rear end, and the cross section of the smoothbore is a triangle; an electromagnetic power device, an extruding rod, a carrier and a curly welding baffle plate are arranged in the smoothbore from back to front in sequence; and a carrier hole groove is formed in one side of the front end of the gun barrel, the carrier hole groove penetrates the smoothbore vertically, a wiring sliding groove extends from the front end to the rear end of the bottom part of the gun barrel, and the wiring sliding groove penetrates the bottom wall. The strain gauge automatic welding and pasting device provided by the invention can position the location of a strain gauge accurately, realizes the automatic welding of wiring terminals and automatic pasting of the strain gauge, can effectively improve the pasting quality of the strain gauge, saves pasting time, and can be used by workers with or without manual pasting experience.

Description

technical field [0001] The invention belongs to the field of engineering testing, and in particular relates to an automatic welding and pasting device for strain gauges. Background technique [0002] In engineering testing, in order to test the strain of materials or components, and then obtain the stress of materials or components, strain gauges are often used for measurement. The sticking quality of the strain gauge is a key factor for the success of the experiment. However, the sticking of strain gauges in the process of engineering testing is manually operated by the experimenter, and the sticking quality of strain gauges depends on the proficiency of the operator. Due to the complicated manual pasting operation, the pasting position is difficult to control or the uneven pressing during pasting not only leads to waste of strain gauges but also wastes valuable time. In addition, the connection between the traditional strain gauge wire and the terminal and between the te...

Problems solved by technology

However, the sticking of the strain gauges in the process of engineering testing is manually operated by the experimenter, and the sticking quality of the strain gauges depends on the proficiency of the operator.

Due to the complicated manual pasting operation, the pasting position is not easy to control or the pressing is uneven during pasting, which not only leads to waste of strain gauges but also wastes precious time

In addition, the connection between the traditional strain gauge wire and the terminal and between the terminal and the wire is also connected together by manual welding. During the operation, the welding quality depends on the proficiency of the tester, and there is a problem of quality assurance rate. There are also problems of time-consuming and consumables
