Method and auxiliary device for pasting strain gages on circular bar and strain gage placing template

The invention relates to a method and auxiliary device for pasting strain gages on a circular bar and a strain gage placing template. The method includes the steps that firstly, a plurality of strain gages are fixed to transparent adhesive tape at intervals in a parallel mode; then, the transparent adhesive tape is straightened and flat placed on a sample abutting block provided with a sample groove, the first strain gage to be pasted is controlled to be aligned with the sample groove and is coated with a binding agent, the sample abutting block is made to abut upon the sample afterwards, the other strain gages are coated with binding agents after the first strain gage is firmly pasted, the sample abutting block is made to slightly descend by pulling the other end of the adhesive tape, the sample is rotated so that the cylindrical surface of the sample can be wrapped by the adhesive tape, and then the strain gages can be pasted. By adopting the strain gage pasting auxiliary device and the strain gage placing template to paste the strain gages on the circular bar, pasting flatness is improved, the interval parallelism and uniformity of the strain gages are guaranteed, and the multiple strain gages can be pasted at one time.
