一种车床用自动定位装置
摘要：
一种车床用自动定位装置，它涉及车床加工技术领域。它包括机床主轴、气缸、法兰盘、法兰座、顶盘、顶尖套筒、顶尖、顶盘气缸，机床主轴与法兰盘连接，汽缸设置在主轴内的法兰座上，法兰座的另一端与法兰盘内的顶尖、顶尖套筒连接，机床尾座上设置有顶盘、顶盘气缸，顶盘与顶盘气缸连接。本发明省去了打定位销孔的工序，缩短了加工周期，提高了工作效率，加工工序中减少了定位环节，减少了精度损失，工件的定位更加自动化。
摘要（英）：

The invention relates to the technical field of lathe machining, in particular to an automatic positioning device for a lathe. The automatic positioning device comprises a machine tool spindle, an aircylinder, a flange plate, a flange base, a top disc, a center sleeve, a center and a top disc air cylinder. The machine tool spindle and the flange plate are connected, the air cylinder is arranged on the flange base inside the spindle, the other end of the flange base is connected with the center inside the flange plate and the center sleeve, the top disc and the top disc air cylinder are arranged on a machine tool tailstock, and the top disc and the top disc air cylinder are connected. The procedure of punching a positioning pin hole is omitted, the machining period is shortened, the working efficiency is improved, a positioning link is omitted in the machining process, the precision loss is lowered, and positioning of a workpiece is more automatic.
