Rotating shaft control device of numerically-controlled machine tool and control method thereof

Abstract

The invention discloses a rotating shaft control device of a numerical control machine tool, and the device comprises a controller, a motor driver and a hand wheel. The controller is independent of amachine tool and comprises a data processing unit, a CNC232 communication interface, a transfer station used for connecting the CNC232 communication interface and a CNC machine tool, a CNC input and output interface connected with the CNC machine tool, a driver input and output interface connected with the motor driver, a hand wheel communication interface used for being connected with the hand wheel, a mode selection switch used for selecting a communication protocol format and an indication lamp. The transfer station comprises a circuit board, and an external memory, a main control communication chip, a first port connected with the CNC232 communication interface and a second port connected with the CNC machine tool which are arranged on the circuit board. The invention further disclosesa numerical control machine tool rotating shaft control method. According to the numerical control machine tool rotating shaft control device and the control method thereof, the universality of the CNC machine tool is improved, and the productivity is improved.

Description

technical field [0001] The invention belongs to the technical field of numerical control machining, and in particular relates to a rotating shaft control device of a numerical control machine tool and a control method thereof. Background technique [0002] CNC (full name Computerised Numerical Control) is a numerical control machine tool, which is a high-precision, high-efficiency automatic machine tool, which automatically processes the processed parts according to the pre-programmed processing program. At present, most CNC system manufacturers only open three-axis (usually X, Y, Z three orthogonal linear coordinate axes) processing functions to domestic CNC machine tools. If more axial processing functions need to be added, additional expansion is required. . In the extended processing function, "rotary axis" processing is more common, that is, to perform rotary processing around the X-axis or Y-axis. Among them, the rotary axis around the X-axis is called the fourth axis...

AI Technical Summary

Problems solved by technology

[0003] However, adding the fourth-axis and fifth-axis processing functions requires the original CNC system manufacturer to open the corresponding authority and purchase matching drivers and motors. The reason is that drivers and motors between different CNC system manufacturers are often not available Shared, poor versatility

For example, if you use Japan's FANUC (FAUNC) CNC system, if you want to increase the function of the fourth or fifth axis, you can only buy servo controllers and motors produced by Japan's FANUC company, and you cannot use Germany's Siemens (SIMENS) company. servo controller and motor
