Vehicle crankshaft casting head cutting machine tool

Abstract

The invention discloses a vehicle crankshaft casting head cutting machine tool, which is used for cutting the casting heads at the two ends of two vehicle crankshafts which are cast into a whole at the same time, and comprises a bed body and a tank body arranged on the bed body; a working table which can move is arranged on the bed body; a clamping device which is used for positioning and clamping the machined crankshaft castings is arranged on the working table; cutting devices are symmetrically arranged on the two sides, which are parallel to the axes of the crankshafts, of the clamping device; and the cutting devices have four cutting grinding wheels which can feed from the outside to the inside along the radical direction of the two crankshafts to cut the casting heads at the two endsof the crankshafts at the same time. According to the vehicle crankshaft casting head cutting machine tool, two cutting devices are adopted to cut the casting heads of two vehicle crankshafts which are cast into a whole, four cutting blades are fed along the radical direction of the crankshafts at the same time, and through one time of loading, the cutting of the casting heads at the two ends of the two vehicle crankshafts which are cast into a whole is accomplished at one time; and thus, the working efficiency is improved greatly, the loading number of a workpiece is reduce, the labor intensity is reduced, and the requirements for mass operation are met.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a cutting machine tool used for cutting and removing the riser of an automobile crankshaft. Background technique [0002] During the casting process of automobile crankshafts, two crankshafts are usually cast in one box, and the two ends of the crankshafts are respectively provided with sprue risers to form two crankshafts as one piece of cast parts. , to send a single crankshaft into the metal cutting process. Nowadays, when cutting the riser at both ends of the crankshaft, the usual method is to cut the riser at one end of the crankshaft first after clamping the workpiece on the cutting machine, then loosen the clamping device, turn the crankshaft around, and clamp it. Then cut the sprue at the other end. This cutting method needs to be continuously clamped, loosened, turned around, and then cut and processed during operation, resulting in low work eff...
