Auxiliary device for drilling crankshaft of compressor

The utility model provides a compressor crankshaft drilling auxiliary device, which relates to the crankshaft field and comprises a machine base, a clamping base and chucks, one end of the clamping base is provided with an adjusting base, one end of the adjusting base is provided with the chucks, the inner sides of the chucks are provided with clamping grooves, clamping rods are arranged in the clamping grooves on the inner sides of the chucks, and the clamping rods are arranged on the clamping bases. When the clamping head clamps the crankshaft rod, the threaded clamping rod in the clamping groove is in contact with the crankshaft rod, the friction force between the threaded clamping rod and the smooth surface of the crankshaft rod can be increased through the design of the threaded clamping rod, the conditions of slipping and deviation are avoided, and after clamping is completed, the crankshaft rod is clamped through the clamping rod. Clamping pressure can be detected through the pressure sensors, in the u
