Automatic tailstock control method for cylinder-driven numerical control machine lathe capable of realizing rigid tapping

Abstract

The invention provides an automatic tailstock control method for a cylinder-driven numerical control machine lathe capable of realizing rigid tapping. According to the automatic tailstock control method, a connecting device for connecting and disconnecting a lathe saddle and a tailstock of a numerical control lathe is adopted; the connecting device comprises a connecting column, a rotating arm component, a driving component and a screw tap component; the rotating arm component comprises a rotating arm, a rotating shaft, a shaft sleeve and a main gear; the shaft sleeve is fixed to the front side surface of the tailstock of the numerical control lathe; the rotating shaft penetrates through the shaft sleeve; the front end of the rotating shaft is fixedly connected with the rotating arm; the other end of the rotating shaft is fixedly connected with the main gear; the front end of the rotating arm is provided with a hook part which can be clamped into a ring slot; the driving component comprises a gear rack, a cylinder, an electromagnetic reversing valve, a gear rack guide groove, a reset switch and a controller; the controller is installed inside a power distribution cabinet of the lathe and is electrically connected with a numerical control system and the electromagnetic reversing valve; and the reset switch is installed in front of the saddle of the numerical control lathe and iselectrically connected with the controller.

Description

[0001] This application is the application number: 2016106054432, the name of the invention is: an automatic control method for the tailstock of a CNC lathe with rigid tapping driven by a cylinder, the filing date is: a divisional application of the invention patent application on July 29, 2016 . Technical field [0002] The application relates to the technical field of numerical control lathes, and specifically relates to an automatic control method for the tailstock of a numerical control lathe that is driven by a cylinder and can be rigidly tapped. Background technique [0003] CNC lathe is one of the most commonly used automatic processing equipment in mechanical cutting, but the tailstock of general CNC machine tools cannot feed automatically. Therefore, when tapping process on CNC lathe, manual operation can only be carried out, which is time-consuming and labor-intensive, and processing efficiency Low, and generally only use floating tapping to process threaded holes, and a...

Problems solved by technology

[0003] 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
