Rolling pin wear detection device and detection method thereof

The invention discloses a rolling pin wear detection device and a detection method thereof, the device comprises a detection disc assembly, a probe assembly and a detection object assembly, the detection object assembly comprises a nut assembly and a screw rod, the detection disc assembly is fixed on the screw rod, and the probe assembly is fixed on the nut assembly. The swing of the nut assembly of a detected object in the screw rod is transmitted to the swing of the probe assembly on the dial of the detection disc, and the abrasion condition of the rolling pin in the nut assembly is calculated through detection of the swing amount angle and conversion. According to the invention, the wear condition of the rolling pin is converted into the swing quantity of the probe on the detection disc, so that the disassembly for detecting the wear of the rolling pin is avoided, the problem of overlong wear detection time of the LS lock rolling pin can be solved, the maintenance efficiency is improved, the labor and time
