Miniature drawing instrument calibration device

Abstract

The utility model provides a miniature drawing instrument calibration device which comprises a bottom supporting seat, a drawing instrument mounting seat is fixedly connected to the upper surface of the bottom supporting seat, a standard dynamometer is connected to the upper surface of the drawing instrument mounting seat in a sleeved mode, and an upper circular bearing plate is arranged on the upper surface of the standard dynamometer and located at the top of the drawing instrument mounting seat. A fastening nut is arranged on the surface of the top of the upper circular bearing plate, and a positioning ring is arranged on the surface of the lower end of the upper circular bearing plate, so that the problems that standard device installation measurement cannot be carried out on instruments such as rivet drawing instruments, and a universal tension and pressure testing machine needs to be matched for detection during detection; meanwhile, only the horizontal position of the drawing instrument body can be adjusted, and the problem that the axis between the drawing instrument body and the standard dynamometer deviates cannot be solved.
