图1所示为支承座,其中开槽和两内端面的加工,通常安排在B665或B5032牛头刨床或插床上进行,这样生产效率低。为了提高生产效率,笔者设计一个如图2所示的简易双面镗铣头,在T611镗床上使用,能保证质量要求,也提高了效率,现简介如下: 一、简易双面镗铣头的结构简易双面镗铣头的尺寸结构,见图2。它是由镗铣头座1,莫氏6号锥体2,圆螺母3等零件所组成。莫氏6号锥体与镗床主轴内锥孔相配合,传递切削力矩。镗铣头的外圆直径设计应满足下式:1/2(D-d)=h+10式中:D—外圆直径:本铣头为400mm; d—镗杆直径:T611为110mm; h—中开槽的深度:本支承座为130mm。当工件的中开槽加工余量较小时,也可设计成如
Figure 1 shows the support seat, in which the grooving and the machining of the two inner end faces are usually done on a B665 or B5032 shaper or slot machine, which results in low productivity. In order to improve production efficiency, the author designed a simple two-sided boring milling head shown in Figure 2, used on the T611 boring machine, to ensure quality requirements, but also improve the efficiency, are summarized as follows: First, the simple two-sided boring milling head Structure Simple double-sided boring milling head size structure, shown in Figure 2. It is boring and milling head base 1, Mohs 6 cone 2, round nut 3 and other components. Mohs 6 cones and boring spindle spindle bore with the transfer of cutting torque. Boring and milling head diameter of the outer circle should be designed to meet the following formula: 1/2 (Dd) = h +10 Where: D- diameter: the milling head is 400mm; d- boring bar diameter: T611 is 110mm; h- The depth of the groove: The bearing seat is 130mm. When the workpiece grooving machining allowance is small, it can also be designed as
