The utility model provides an insulator deviation detection device which includes a positioning part used for mounting the detecting insulator and installed on a detecting workbench, a driving part installed on the detecting workbench and drivingly connected with the positioning part and used for driving the rotation of the positioning part, and a detecting unit slidably installed on the detecting workbench and used for detecting the axial deviation and the meridional deviation of the insulator. The insulator's automatical rotation is realized via using the insulator deviation detection device to detect the deviation of the insulator, which can solve the low automatic degree for the detection of manual test in the current technology.
