在加工挖泥机减速箱体时,低档孔内有一条轴承挡圈槽,加工很困难。为此我们设计制造了一种切槽刀具。结构及原理刀具结构如图所示。刀具体3以工件已加工孔A和端面B定位,采用较紧的过渡配合。传动锥轴9传递钻床动力,经柱销7、万向接头8,连接进刀传动轴10,再经键11传动刀具动力轴2,带动刀具22作顺时针的切削运动。同时扳动钻床进给手柄,使钻杆作轴向进给。通过传动锥轴、万向接头使进刀传动轴作轴向进给。在进刀传动轴端楔形滑
In the processing of dredging machine gearbox, the lower hole has a bearing ring groove, processing is very difficult. For this reason we designed and manufactured a grooving tool. Structure and principle Tool structure as shown. Tool 3 to the workpiece has been processed hole A and end B positioning, with a tight transition with. The transmission cone 9 transmits the power of the drilling machine, and is connected with the propeller shaft 10 through the pin 7 and the universal joint 8, and then the power shaft 2 of the cutter is driven by the key 11 to drive the cutter 22 to make a clockwise cutting motion. At the same time pull the drill feed handle, the drill rod for axial feed. Through the drive cone shaft, universal joint to feed the drive shaft for axial feed. In the feed drive shaft end wedge slip
