用单刀拉削和铣削的方法加工孔直线油槽,因受内孔小的限制,质量不稳定,产量不高。我厂工装组和刨工同志一起,成功地利用牛头刨床的直线往复运动,配加⊥形活动刀杆和模板来加工油槽(如图),既保证了质量,又提高了生产率。光洁度为▽6以上,单件工时为20秒。刀、模具制造简单,适合大批量生产。结构原理与动作以我厂生产螺纹机,小绳轮为例。滑枕前进时,⊥形刀杆上的滚轮7沿模板5运动,
With single-point broaching and milling method of processing hole straight groove, because of the small hole restrictions, the quality is unstable, the yield is not high. I plant tooling group and planing comrades together, the successful use of shaper bed linear reciprocating motion, with ⊥-shaped movable cutter bar and the template to process the tank (see photo), both to ensure the quality and increase productivity. Finish is ▽ 6 or more, single piece of work time is 20 seconds. Knife, mold manufacturing simple, suitable for mass production. Structural principle and action I plant the production of thread machines, small sheaves, for example. When the ram advances, the roller 7 on the ⊥-shaped arbor moves along the template 5,
