我厂在今年1月上旬制成一台适用三吨锤的D轴风动调头器,其结构如附图所示。这台调头器可以借风缸的作用使承受D轴的托台上升,又因装有立式滚珠轴承,可使D轴在平面上,做360°的回转。代替了过去用人工压大钳子调头的笨重劳动。由于采用了这台简易设备,这道工序可以节省一名工人,而且调头时间也大大缩短了。过去每个轴调头三次,要三分钟,现在只要一分 I plant in early January of this year made a suitable three-ton hammer D-axis pneumatic Tiara, its structure as shown in the figure. The tweezers by the role of the cylinder to withstand the D-axis pallet rise, and because of vertical ball bearings are equipped, the D-axis in the plane, so 360 ° of rotation. Instead of bulky work that used manual pressure to turn pliers around. Thanks to this simple equipment, this process can save a worker, and turnaround time has also been greatly reduced. In the past, each axis was thrown three times, to three minutes, now only one point
