Embodiment Construction

[0020] Referring to the accompanying drawings, the strain gauge sticking tool of the present application includes a first handle 1 and a second handle 2, and the proximal ends of the first handle 1 and the second handle 2 are hinged by a pin shaft 3, and the first handle 1 The front end is the first clamping handle 4, the front end of the second handle 2 is the second clamping handle 5, the first clamping handle 4 cooperates with the second clamping handle 5, and the front end of the first clamping handle 4 has a Pasting station 6 corresponding to the strain gauge.

[0021] In order to prevent the adhesive from sticking to the sticking table 6 when the strain gauge is pasted, a plastic non-stick layer is inlaid on the upper surface of the sticking table. Plastic non-stick patch.

[0022] The first clamping handle 4 and the second clamping handle 5 are an arc-shaped structure that is sunken relative to the pasting table 6. Such a structure makes the pasting table 6 protrude re...

Abstract

The invention discloses a strain gauge pasting tool and a pasting method, and belongs to the field of aircraft strength tests. The strain gauge pasting tool comprises a first handle and a second handle, wherein the near front ends of the first handle and the second handle are hinged; the front end of the first handle is a first clamping handle; the front end of the second handle is a second clamping handle; the first clamping handle is matched with the second clamping handle; a rubber pad is arranged on a pasting surface of the first clamping handle and the second clamping handle, and is usedfor clamping one end of a strain gauge; a pasting table corresponding to the strain gauge is arranged at the front end of the first clamping handle; and the size of the pasting table is matched with that of the strain gauge. According to the strain gauge pasting tool and the pasting method, the strain gauge achieves an ideal pasting effect, the pasting quality of the strain gauge is higher, and the pasting of the strain gauges at different angle inclined plane positions of a test piece can be realized by adjusting the angles of a handle rod and the clamping handles.

Description

technical field [0001] The application belongs to the field of aircraft strength tests, and in particular relates to a tool for pasting strain gauges in a narrow area of ​​an aircraft in an aircraft strength test. Background technique [0002] Before the strength test of aircraft components and the whole machine, strain gauges need to be pasted to monitor the stress level in the assessment area, which is one of the important measurement methods of strength test. There are many kinds of strain gauges. Metal test pieces generally use resistance strain gauges, including uniaxial and triaxial strain gauges, and their maximum size is about 10mmX10mm. For the pasting position of the strain gauge with a large space, the pasting can generally be carried out manually. For some important narrow areas of docking and occlusion, it is impossible to manually approach and paste. Due to the limited accessibility of the patch, it is difficult or even impossible to paste the strain gauge, s...
