铁风扇轴端面夹具,其结构简单、易于制造、工效高,比车床车端面,提高工效五倍以上。图示为该夹具夹压工件情况,一块压板2夹压8个工件,单边4件,按比例增加夹具主体槽的高度,单边可压7件、10件等,但件数越多,压紧力越差,所以单边压4件为宜。夹具主体V型槽底角为107°34＇,槽宽B=D+2Dsin36°13＇,D为工件毛坯直径。工件毛坯为冲断或切断棒料。夹具主体高度H视工件毛坯
Iron fan shaft end fixture, its simple structure, easy to manufacture, high efficiency, lathe car than the end face, to improve work efficiency five times. The figure shows the fixture for clamping the workpiece, a plate 2 clamping 8 workpieces, unilateral 4, in proportion to increase the height of the fixture body groove, the pressure can be unilateral 7, 10, etc., but the more the number of pressure Tight worse, so unilateral pressure 4 is appropriate. Fixture body V-groove bottom angle 107 ° 34 ’, groove width B = D + 2Dsin36 ° 13’, D is the workpiece blank diameter. Blank workpiece for the thrust or cut off the bar. Hatch body height H workpiece blank
