为了扩大镗瓦机的工作范围,我们对它进行了改装。改装后,除了不能镗台阶孔外,其它许多尺寸大于镗杆的孔都可以加工。改装方法如下。一.在原工作台上增加一个回转工作台,其构造如图1所示:工作台面1上有三个 T 形槽,安放压板螺栓用。下面有回转分度盘2,可使工作台回转360°。摇动丝杠7,可使工作台沿燕尾横向移动,丝杠螺距为5毫米。工作台靠台座8支撑,在定位块9的限制下,可沿镗瓦机工作台中间的 T 形槽纵向移动。由此,可达到回转工作台前、后、左、右调整和转换角度之目的。这样,加工一些小零件就方便多了。譬如可以修复或加工内、外平衡臂、拖拉机的前横梁支点、羊角轴孔、东方红—75的操纵机构等等。
In order to expand the scope of work boring machine, we have it modified. After retrofitting, in addition to not boring step holes, many other sizes larger than the boring bar can be machined. Modified method is as follows. 1. In the original table to add a rotary table, the structure shown in Figure 1: There are three T-slot on the work surface 1, placed platen bolts. Below the rotary indexing plate 2, the table can be rotated 360 °. Shake the lead screw 7 to move the worktable transversely along the dovetail with a lead screw pitch of 5 mm. The workbench is supported by the pedestal 8, and under the restriction of the positioning block 9, it can move longitudinally along the T-shaped groove in the middle of the workbench of the boring machine. Thus, to reach the rotary table before, after, left and right adjustments and conversion point of view. In this way, the processing of some small parts more convenient. For example, can be repaired or processed inside and outside the balance arm, tractor front beam fulcrum, crooked shaft hole, Oriental Red -75 control mechanism and so on.
