A control method for tailstock of CNC lathe that can realize rigid tapping

Abstract

The invention provides a numerical control lathe tailstock control method capable of achieving rigid tapping. A connection device achieving connection and disconnection of a saddle and the tailstock of a numerical control lathe through a motor is adopted and comprises a connection column, a rotating arm assembly, a driving assembly and a screw tap assembly. The screw tap assembly is installed in a tube sleeve of the tailstock of the numerical control lathe, the middle of the connection column is provided with an annular groove with inclined faces as the two side faces, the bottom of the annular groove is provided with a sensor, the two side inclined faces of the annular groove are each provided with a pressure sensor, the connection column is fixedly connected with the saddle of the numerical control lathe, the shaft end of the connection column and the side face of the tailstock are provided with a pair of sensors, the rotating arm assembly comprises a rotating arm, a rotating shaft, a shaft sleeve and a limiting pressure block, the driving assembly comprises a pair of belt drivers, a driving motor, a reset switch and a controller, the controller is installed in a distribution cabinet of the lathe, the reset switch is installed on the front face of the saddle of the numerical control lathe, and the driving motor is fixedly connected with the tailstock of the numerical control lathe and electrically connected with the controller.

Description

technical field [0001] The application relates to the technical field of numerical control lathe control, in particular to a control method for a tailstock of a numerical control lathe capable of realizing rigid tapping. Background technique [0002] CNC lathes are one of the most commonly used automatic processing equipment in mechanical cutting. However, the tailstock of general CNC machine tools cannot be fed automatically. Therefore, when performing tapping processes on CNC lathes, manual operations can only be performed, which is time-consuming and labor-intensive. Low, and generally only floating tapping can be used to process threaded holes, and a set of special tools is required for floating tapping, resulting in higher processing costs. Contents of the invention [0003] Aiming at the existing technical defects, the present invention provides a CNC lathe tailstock automatic feed control method capable of rigid tapping function, which uses a connection device for e...
