Milling and drilling integrated batch machining equipment for crankshafts

Abstract

The invention discloses crankshaft milling and drilling integrated batch machining equipment. The equipment comprises a base; the multiple clamping mechanisms are used for fixing the crankshaft and are arranged on the base in the first direction, according to the arrangement sequence, the multiple clamping mechanisms of the front half section form a first machining unit, and the multiple clamping mechanisms of the rear half section form a second machining unit; the axis of the crankshaft is arranged in the second direction, and the first direction is perpendicular to the second direction. Drilling mechanisms are arranged on the two sides of the first machining unit respectively, a drilling mechanism is arranged on one side of the second machining unit, and a groove milling mechanism is arranged on the other side of the second machining unit; the drilling mechanism and the groove milling mechanism are both driven by a displacement driving mechanism to move in the second direction. According to the machining equipment, milling and drilling machining of crankshafts can be achieved in batches, and the machining efficiency of the crankshafts is effectively improved.

Description

technical field [0001] The invention relates to the technical field of compressor crankshaft processing devices, in particular to a crankshaft milling-drilling integrated batch processing equipment. Background technique [0002] The crankshaft is the most important component in the compressor. It bears the force transmitted from the connecting rod and converts it into torque output through the crankshaft and drives other accessories to work. The processing of the crankshaft is cumbersome, and structures such as slots and holes are often required on the body; crankshafts with different structures require different devices for processing, and even different structures of the same crankshaft may require different equipment for processing; figure 1 Shown is a kind of relatively common crankshaft, and the shaft body (200) of crankshaft (100) is provided with eccentric block (300); Coaxial small holes and large holes also need to mill the end of the crankshaft (400); the current...
