采用小锥度心轴精车齿坯外圆和端而,在设备条件较差,且小批量生产中应用较广。但该加工工艺的缺点是心轴和齿坯装卸很费劲,劳动强度大,还容易将心轴压扁,影响了齿坯的加工精度。为此,我设计了一种如图所示的齿坯加工用心轴装卸器、经使用, The use of small taper mandrel fine car body billet and the end, while in poor condition of equipment, and small batch production is widely used. However, the shortcomings of the processing technology is the mandrel and tooth billet loading and unloading is laborious, labor-intensive, but also easy to flatten the mandrel, affecting the accuracy of tooth blank machining. For this reason, I have designed a mandrel handler for gear blanks, as shown,
