Abstract

Disclosed is a crankshaft mirror capable of preventing the occurrence of abnormal rocking motion of a swing head caused by swarf generated accompanying cutting. The upper end of a ball screw shaft (31) configuring a swing drive mechanism (24) of a swing head (21) swingably attached to a slide (8) is rotatably supported by a bearing device (33). Meanwhile, the lower end of said ball screw shaft (31) is in a free end state, and on the bottom end of the ball screw shaft (31) in the slide (8) a chute (60) is provided for expelling swarf generated accompanying cutting.

Description

technical field [0001] The present invention relates to a crankshaft milling machine for cutting pin journals and main journals of crankshafts used in engines and the like. Background technique [0002] Conventionally, for example, a crankshaft milling machine disclosed in Patent Document 1 is well known. The crankshaft milling machine is configured so that a rotary tool revolves around the workpiece while rotating around the workpiece (crankshaft) so that the pin neck portion of the workpiece, the spindle The neck is cut. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent No. 2529100 [0006] Such as Figure 10 As shown in (a) to (c), the crankshaft milling machine 100 according to Patent Document 1 includes a slide provided on the bed 102 movably in the Z-axis direction parallel to the horizontal axis of the workpiece (crankshaft) 101 to be machined. Saddle 103. The saddle 103 is provided with a slider 104 movably along...
