我厂在加工长300公厘的孔时,曾用钻床铰制,铰刀常折断。改用人工铰制后,每日只能铰3件(每件有20个φ12±0.03的孔),还不能保证质量。后来在老师傅樊元德的钻研下改进了铰孔的工具和铰刀,解决了我厂铰长孔的困难,提高效率10倍,并且保证了质量,现将它介绍如下: (一)铰孔工具的构造:1是斜柄(插入钻床主轴),2是油杯(大小随意制造),3是油杯紧固螺帽(斜锥纹),4是铰刀杆,5是铰刀。使用时,钻床主轴的转速是100转/分,大量注油(冷却液),使油能把孔内的铁屑冲下。
I plant processing 300 mm long hole, had used drilling machine hinge, reamer often broken. Switch to artificial hinge, the hinge can only 3 pieces per day (each piece has 20 φ12 ± 0.03 holes), but also can not guarantee the quality. Later, under the guidance of the teacher Fan Yuande reaming tools and reamers improved, I solved the problem of plant long holes, improve efficiency 10 times, and to ensure the quality, now it is introduced as follows: (A) reaming tools : 1 is the bevel handle (insert drill spindle), 2 is the oil cup (the size of free to make), 3 is the oil cup fastening nut (tapered), 4 is the reamer rod, 5 is the reamer. When used, the drilling spindle speed is 100 rev / min, a lot of oil (coolant), so that the oil can be washed down the hole iron.
