在工具制造中,拉刀刃磨床往往只用来制造或修复拉刀时的刃磨。我厂在加工某产品所需工装中如图1所示的定位元件,由于圆弧半径大,精度及硬度要求高(HRC53～58)。造成加工及检测困难,我们设计并制造了一种简易磨具,成功地解决了该件的加工,同时也扩大了拉刀刃磨床的使用。 磨具的结构示意简图如图2所示,该磨具中的底板3须进行调质HRC28～32,底板的两面进行磨削,以保证磨具的平直度及必要的强度、刚度。 在加工时,将底板3固定在回转工作台1上,插上回转销2,转动工作台,找正外圆,使回转工作台 In toolmaking, the broach sharpener is often used only to make or repair sharpening of the broach. I plant in the processing of a product required tooling shown in Figure 1, the positioning element, due to the large arc radius, high precision and hardness (HRC53 ~ 58). As a result, we designed and manufactured a simple abrasive tool that successfully solved the machining of the part and also broadened the use of the broaching edge grinding machine. Schematic diagram of the abrasive structure shown in Figure 2, the abrasive in the bottom plate 3 to be tempered HRC28 ~ 32, both sides of the floor grinding, to ensure the flatness of the abrasive and the necessary strength and stiffness. During processing, the bottom plate 3 is fixed on the rotary table 1, the rotary pin 2 is inserted, the rotary table is rotated to find the outer circle, and the rotary table
