我厂加工关节销上的油槽时,过去是在车床上车制,经常发现加工出来的油槽两头宽中间狭或损坏车床小刀架。后来我们改进了一种工具,利用钻床来加工,就消除了这种现象。这种工具的结构如附图,1是底座,固定在钻床工作台上。2是主轴套,与主轴3配合。在主轴3上开有与要加工的油槽相同的滑槽A,螺钉销4就伸在滑槽A内。5是固定钻模板,6是钻套,工件是靠螺纹装在主轴3上,在主轴的另一端装有手柄7。当钻头通过钻套在工件上加工时,就可直接来转动
I plant processing joint pin on the tank, the past is in the lathe system, often found out of the two ends of the oil tank width narrow or damaged lathe knife holder. Later, we improved a tool to use the drilling machine to process, to eliminate this phenomenon. The structure of such tools as shown in the figure, 1 is the base, fixed on the drilling table. 2 is the main sleeve, with the spindle 3 with. The spindle 3 is provided with the same chute A as the oil groove to be machined, and the screw pin 4 extends in the chute A. 5 is a fixed drill template, 6 is a drill sleeve, the workpiece is threaded on the spindle 3, the other end of the spindle equipped with a handle 7. When the drill bit through the drill sleeve in the processing of the workpiece, you can directly turn
