我們在普通車床上成批生产軸类零件,每班装卸达150次左右。原来使用具有螺旋副夹紧的鸡心夹,劳动强度大、耗費工时多,現在革新采用“可調快速鸡心夹”,这种鸡心夹在生产实踐中証明有很多优点:(1)使用方便,节約工时,减輕劳动力;(2)夹紧可靠;(3)能适应軸徑尺寸及公差的較大变化;(4)結构簡单,制造方便。这种“可調快速鸡心夹”的結构原理,是利用偏心和V形体夹紧,利用螺旋副調节軸徑尺寸,其最小可調量为1/2螺距。它由偏心压杆2、調节套3、心軸6和鸡心夹体4組成(如图所示)。其使用过程:首先选擇D的偏差在1/2螺距內的成批軸类零件,再分批調节調节套到适当位置,装上車
We produce mass production of shaft parts in ordinary lathe, loading and unloading of about 150 times per class. The original use of spiral clamp with the heart folder, labor-intensive, time-consuming and more, and now the use of innovative “adjustable fast heart-clip”, the heart of this clip in the production of the pro proved to have many advantages: (1) easy to use, Save working hours, reduce labor force; (2) reliable clamping; (3) can adapt to larger changes in shaft diameter size and tolerance; (4) simple structure, easy to manufacture. The structure principle of this “adjustable fast heart-shaped clip” is to use the eccentric and V-shaped body clamp, the use of helical vice adjust the shaft size, the minimum adjustable amount of 1/2 pitch. It is composed of eccentric pressure rod 2, adjusting sleeve 3, mandrel 6 and center of pinch 4 (as shown). The use of the process: First, select the deviation of D within the pitch of the bulk of 1/2 shaft parts, then adjust the adjustment sleeve in batches to the appropriate location, loading the car
