specific Embodiment -1

[0049] The method for pasting the above-mentioned strain gauges in batches includes the following steps:

[0050] 1) Measure the external dimensions of the notched sample 1 and use CAD (for example, AutoCAD) software to draw the external profile of the notched sample according to the measured dimensions figure 2 .

[0051] 2) According to the sticking requirements of the notched specimen strain gauge 6 of the notched specimen 1 (strain gauge position, spacing, angle, etc.), in the above CAD drawing ( figure 2 ) to mark the sticking position of the notched sample strain gauge 6 with the notched sample strain gauge position marking frame 3 having the same base size as the notched sample strain gauge 6 .

[0052] 3) Outline of the notched specimen figure 2 Draw the location mark point 5 on the outline of the notched sample, and draw the location mark point 4 on the surface of the notch sample 1 .

[0053] 4) Take the profile diagram of the notched sample obtained in step 3)...

specific Embodiment -2

[0061] The method for pasting the above-mentioned strain gauges in batches includes the following steps:

[0062] 1) Use CAD (for example, AutoCAD) software to draw the outline of the gear sample according to the design dimensions of the gear sample 7 Figure 8 .

[0063] 2) According to the sticking requirements of the gear sample strain gauge 12 of the gear sample 7 (strain gauge position, spacing, angle, etc.), in the above CAD drawing ( Figure 9 ) to mark the sticking position of the gear sample strain gauge 12 with the gear sample strain gauge position marking frame 9 having the same base size as the gear sample strain gauge 12 .

[0064] (3) Outline of the gear sample Figure 8 Draw the gear sample outline position positioning mark point 11 on the upper surface, and draw the gear sample position positioning mark point 10 on the gear sample 7 surface.

[0065] 4) Take the profile diagram of the gear sample obtained in step 3) ( Figure 12 ) at a ratio of 1:1 on trans...

Abstract

The invention discloses a batch strain gauge pasting method. The method comprises the main steps that an outline skeleton map of a sample is drawn firstly, strain gauge position mark frames and outline skeleton position locating mark points are marked on the outline skeleton map, and then a drawing is printed to transparent adhesive sticker printing paper; strain gauges are sequentially pasted into the strain gauge position mark frames of the adhesive face of the transparent adhesive sticker printing paper; a base of each strain gauge is uniformly smeared with glue; the transparent adhesive sticker printing paper on which the strain gauges are pasted is pasted onto the sample, and the strain gauges are pressed to exhaust bubbles between the strain gauges and the sample; after the glue is solidified completely, the transparent adhesive sticker is torn off, and batch pasting of the strain gauges is completed. The method has the advantages of being simple, easy to implement and suitable for test articles in various shapes, and the multiple strain gauges with positions and angles distributed unevenly can be pasted effectively.

Description

technical field [0001] The invention relates to the technical field of test and measurement, in particular to a method for pasting strain gauges in batches. Background technique [0002] Strain gauge is a commonly used deformation measurement element, which is widely used in strain measurement, tension and pressure measurement, etc. The strain gauges are glued to the surface of the structure to be measured and follow the deformation of the surface. [0003] In the prior art, the strain gages are mainly pasted by manual scribing and pressing. The testers first determine the pasting position of the strain gages by drawing lines on the surface of the structure to be tested, and then apply glue on the parts where the strain gages need to be pasted, and finally press them with their fingers. The pasting of the strain gauge is completed. Therefore, the paste quality of the strain gauge is affected by the proficiency of the tester. [0004] When pasting a single piece, manual sc...
