我厂加工TMD-4型1吨模锻锤缸套配件时(图1),由于现有设备生产能力不足,自行设计制作了一套镗缸套工装,在普通C630车床上,以小攻大,完成了缸套的加工任务。 鏜缸套工装结构见图2。工件19沿轴向固定在支架4,8的凹槽内,用三个双头螺栓夹紧。镗杆1的一端顶在主轴顶尖上,另一端顶在尾架14装有滚动轴承的活动顶尖上,用千分表找正。支架4、8及尾架14的底部均有V形槽,可沿床面纵向移动,以调节其轴向位置。丝杠3两端用支架2夹持在镗杆1上。棘轮9固定在丝杠右端,并随镗杆一起转动。由于棘爪16的作用,
I plant processing TMD-4-type 1 ton forging hammer liner parts (Figure 1), due to the existing production capacity of less than capable, designed and manufactured a set of boring cylinder tooling, in a common C630 lathe, small attack big , Completed the cylinder liner processing tasks. Boring cylinder tooling structure shown in Figure 2. The workpiece 19 is axially fixed in the recess of the bracket 4, 8 and clamped with three studs. One end of the boring bar 1 is at the top of the spindle and the other end is on the movable center of the tailstock 14 which is provided with a rolling bearing. The bases of the brackets 4, 8 and the tailstock 14 have V-shaped grooves at the bottom for longitudinal movement along the bed to adjust the axial position. The screw 3 is clamped on the boring bar 1 by bracket 2 at both ends. Ratchet 9 is fixed to the right end of the screw and rotates with the boring bar. Due to the action of the pawl 16,
