Hobbing machine cutter holder test platform and test method thereof

The invention discloses a hobbing machine cutter holder test platform and a test method thereof and belongs to the field of measurement and control. The test platform comprises a bed body, a mountingbase, a large column, a sliding plate, a test cutter holder and an eddy current brake. The test cutter holder is composed of a main motor, a gear box and a test cutter bar which are successively in driving connection. The test cutter bar is connected to the output shaft of the eddy current brake through a torque speed sensor at a free end away from the main shaft of the gear box and is provided with a circular grating at a fixed end close to the main shaft of the gear box. The hobbing machine cutter holder test platform of the invention is a test platform for loading the torque of the test cutter holder by the eddy current brake simulating the hobbing machine gear machining condition, and the test platform can also detect the gear box transmission precision of the hobbing machine cutter holder in no-load and loade
