我厂修机车间只有两台普通铣床,这两台普通铣床都缺少铣长齿条的设备,因此在工作上很不方便,并经常影响生产计划。该车间工友王义臣,研究了一种在普通铣床上铣长齿条的工具。现将工具的构造及操作方法介绍如下:工件规格:被加工的齿条长2200公厘,宽35公厘,厚40公厘,10D.P.。材料是生铁。工具构造:工具的构造如附图。图中①是支架,上部装在铣床导轴②上,用螺钉③固定。④是伞齿轮,装在铣床主轴上,并和伞齿轮⑤相啮合。伞齿轮⑤装在轴⑥的一端,另一端装上铣刀⑦,然后用螺帽⑧旋紧。铣刀背后装有垫圈⑨。
Our factory repair shop only two ordinary milling machine, the two milling machines are lacking milling long rack and pinion equipment, so very inconvenient in the work, and often affect the production plan. Wang Yichen, a coworker in the workshop, studied a tool for milling long racks on an ordinary milling machine. Now the tool construction and operation methods are as follows: Workpiece Specifications: The length of the rack is processed 2200 mm, width 35 mm, thickness 40 mm, 10D.P .. The material is pig iron. Tool Construction: The construction of the tool is shown in the attached drawing. ① is a bracket, the upper mounted on the milling machine guide shaft ②, with screws ③ fixed. ④ is a bevel gear, mounted on the milling spindle, and meshing with the bevel gear ⑤. Bevel gear ⑤ mounted on one end of the shaft ⑥, the other end mounted cutter ⑦, and then tighten the nut ⑧. Behind the cutter washer ⑨.
