“机械工人”(冷加工)1958年3期32页介绍的“万能角度方箱”,我认为这一工具有很多地方是可以改进的。首先在调整角度方面,可以不用扇形齿轮和圆柱齿轮传动来达到;工具的结构可以简化。我厂使用的“万能角铁”,它不但结构简单,而旦还能克服上述工具的缺点,现在把它介绍出来,供大家参考。 1.结构:用螺钉12把铰链11固定在固定平板1和活动平板3上,活动平板3可绕铰链11中心回转。在固定平板1的左端用螺钉2固定刻度
“Mechanical Workers” (Cold Working), 1958, No. 3, page 32, introduced the “omnipotent angular square box,” and I think there are many areas where this tool can be improved. First of all, in terms of angle adjustment, it is possible to achieve without fan-shaped gears and spur gears; the structure of the tool can be simplified. I use the factory “universal angle iron”, it is not only simple in structure, but once again overcome the shortcomings of the above tools, now it is introduced for your reference. 1. Structure: The hinge 11 is fixed to the fixed plate 1 and the movable plate 3 by screws 12, and the movable plate 3 can be pivoted about the center of the hinge 11. Fix the scale with the screw 2 at the left end of the fixing plate 1
