一、型式 五面六工位13轴。 二、用途及加工精度 机床用来在45号钢锻造的左右连杆体上进行钻、扩、铣等工序。左右连杆是同时加工的。在每一个连杆上完成钻2个φ9.5毫米螺栓孔,1个φ1.5毫米的油孔和铣1个小槽。两个螺栓孔的孔间距位置精度要求为±0.l毫米,连杆与曲轴配合孔中心位置精度要求±0.05毫米,光洁度为3。槽的深度和宽度的精度均要求+0.15毫米,槽的位置对其端面的精度要求±0.15毫米。
First, the pattern of five-six six-bit 13-axis. Second, the use and processing accuracy Machine used to make the 45 steel forging left and right connecting rod body drilling, expanding, milling and other processes. Left and right link is processed at the same time. Drill two φ9.5 mm bolt holes, one φ1.5 mm hole, and a small slot on each connecting rod. The hole spacing of the two bolt holes is ± 0.11mm, the accuracy of the center position of the connecting rod and crankshaft is ± 0.05mm, and the finish of the hole is 3. The depth of the groove and the accuracy of the width all require +0.15 mm, the position of the groove requires ± 0.15 mm for the precision of its end face.
