我们在加工图1所示的球形瓦座时,采用了图2所示的胎具,在镗床上加工。胎具简单,质量合格,操作方便。胎具结构:刀头8紧固在刀夹7上,刀夹置于刀杆4的叉形槽中,刀杆的另一端插入刀座3中并紧固,平旋盘旋转时,刀座、刀杆、刀夹、刀头随着一起转动,完成了切削运动。推扠1固定在镗杆上,推杆2与推扠连接,推杆与滑座5的孔滑配合,推杆与刀夹采用活节6连接。镗杆伸缩时,则刀头、刀夹绕刀杆端部芯轴摆动,完成走刀运动。加工过程:
When we process the spherical tile shown in Figure 1, we use the tool shown in Figure 2 to machine the boring machine. With simple tools, quality standards, easy to operate. Belt structure: the cutter head 8 is fastened on the holder 7, the holder is placed in the forked groove of the cutter bar 4, the other end of the cutter bar is inserted into the cutter holder 3 and fastened, and when the rotating cutter is rotated, , Arbor, tool holder, cutter head along with the rotation, the completion of the cutting movement. Push fork 1 is fixed on the boring bar, the push rod 2 is connected with the push fork, the push rod is slidably matched with the hole of the sliding seat 5, and the push rod and the tool holder are connected with the articulation 6. When the boring bar is telescopic, the cutterhead and the cutterhead will swing around the end of the arbor to complete the cutter movement. Processing process:
