Abstract

The invention discloses a testing system of cutting force and torque loading reliability of a numerical control turret power knife rest, which comprises a supporting part and a loading part. The supporting part comprises a numerical control turret power knife rest supporting part, a cutting force loading supporting part and a torque loading supporting part. The numerical control turret power knife rest supporting part is fixed at left side below a floor iron, and the torque loading supporting part is located at the right side below the floor iron. The loading part comprises a dynamic cutting force loading part, a cutting torque loading part and a loading bar. The dynamic cutting force loading part is connected with a rotating plate in the cutting force loading supporting part through a 2# sliding plate. The cutting torque loading part comprises an eddy current dynamometer and an elastic coupler. The eddy current dynamometer is installed on a 3# pedestal, the output end of the eddy current dynamometer is connected with the elastic coupler, the elastic coupler is connected with a right end key of the loading bar sleeved with a bearing loading unit, and the left end of the loading bar is fixedly connected with the right end of a power knife seat on the measured numerical control turret power knife rest.

Description
