一、用途手提式测角仪用以测量各种刀具的角度。据目前使用,已应用在测量车刀、刨刀、铣刀、拉刀、铰刀、插齿刀等的前角γ和后角α,车刀、刨刀的刃倾角;钻头、扩孔钻、铰刀的齿顶角2φ等。二、结构测角仪结构如图1,刀口尺10装在座壳1的底板上,重心块8(浇有13克重的铅块)的前后有60°顶尖,顶在前项尖6和支头螺絲9的孔中,可自由转动。前顶尖端面粘附一张印有360°的等分表,每一等分为1°。前顶尖6嵌在盖5的孔中,依靠弹簧7夹紧在座壳1的壳体内。指针4用螺钉2紧固在座壳上,并调 First, the use of portable goniometer to measure the angle of various tools. According to the current use, has been used in measuring the lathe, planer, cutter, broach, reamer, shaper rake and other front angle γ and rear angle α, turning tool, planer blade angle; drill, reaming drill, hinge Tooth tip angle 2φ and so on. Second, the structure goniometer structure shown in Figure 1, knife blade 10 mounted on the base shell seat 1, the center of gravity block 8 (pouring 13 grams of lead) before and after a 60 ° top, the top of the tip 6 and branch Head screw 9 hole, can rotate freely. The front top face is attached with a bisector table printed with 360 °, each equaling 1 °. The front tip 6 is embedded in the hole of the cover 5 and is clamped in the housing of the housing 1 by the spring 7. The pointer 4 is fastened to the seat shell with screws 2 and adjusted
