在铣床上采用简单分度法铣削工件时,由于转动圈数较多,经常会多转或少转圈数使产品报废。为此,设计转动分度手柄的计数装置(见图)。找宽约10mm的铝片,围成与刻度环等直径的铝环1,用紧定螺钉2、螺母3固定在刻度环上,在铝环上分成40等分,逆时针方向标上数字。操作时,将铝环与分度头零线对齐,转动手柄后,看分度头 In the milling machine with a simple indexing method of milling the workpiece, due to the larger number of turns, often turn more or less turn the number of products scrapped. To do this, design a rotary indexing handle counting device (see photo). To find a width of about 10mm aluminum sheet, surrounded with a graduated ring and other diameter aluminum ring 1, with a set screw 2, nut 3 is fixed on the scale ring, divided into 40 equal parts on the aluminum ring, counterclockwise marked with numbers. Operation, the aluminum ring and indexing line zero alignment, turn the handle, see sub-head
