螺栓杆部环形槽的滚压强化方法及车床用滚压强化装置
摘要：
本发明公开了一种螺栓杆部环形槽的滚压强化方法及车床用滚压强化装置，本发明在对螺栓杆部环形槽的表面进行滚压强化处理时，采用车床对其进行滚压强化处理，即将需要进行滚压强化处理的螺栓的一端装夹在车床的卡盘上，将其另一端用车床的顶尖顶紧，然后在车床的刀架上安装上车床用滚压强化装置，在该车床用滚压强化装置上设有能够压在螺栓杆部环形槽上的滚轮，将该滚轮对正并顶压在螺栓杆部上需滚压强化的环形槽后，通过车床卡盘带动螺栓转动，这样即可通过滚轮顶压在螺栓杆部环形槽时所产生的摩擦力来带动滚轮一起转动，从而实现滚轮对螺栓杆部环形槽的滚压强化处理。本发明具有加工效率高、成本低、质量好、结构简单、使用方便等优点。
摘要（英）：

The invention discloses a bolt bar part circular groove rolling strengthening method and a rolling strengthening device for a turning lathe. When a surface of a bolt bar part circular groove is rolledand strengthened, the turning lathe is adopted for rolling strengthening on the bolt bar part circular groove, one end of a bolt needing to be rolled and strengthened is clamped on a chuck of the turning lathe, the other end of the bolt is tightened by a centre of the turning lathe, then the rolling strengthening device for the turning lathe is arranged on a tool holder of the turning lathe, a rolling wheel capable of pressing the bolt bar part circular groove is arranged on the rolling strengthening device for the turning lathe, after the rolling wheel is aligned at and ejects the bolt bar part circular groove needing to be rolled and strengthened, the chuck of the turning lathe drives the bolt to rotate, and a friction force generated when the rolling wheel ejects the bolt bar part circular groove can drive the rolling wheel to rotate together, so that the bolt bar part circular groove is rolled and strengthened through the rolling wheel. The bolt bar part circular groove rolling strengthening method and the rolling strengthening device for the turning lathe provided by the invention have the beneficial effects of high processing efficiency, low cost, good quality, the simple structure, convenience in use and the like.
