Numerical control machine tool

Abstract

The invention provides a numerical control machine tool, belongs to the technical field of mechanical equipment and solves the problem that the moment transmitted to a spindle cannot satisfy the machining requirement when the motor of the existing numerical control machine tool operates at low speed, and machining precision is low. The numerical control machine tool comprises a frame and a workbench disposed on the frame. A linkage device is disposed between the workbench and the frame. A cutter transmission control cabinet is disposed on the frame opposite to the workbench. An up-down lifting device is disposed between the cutter transmission control cabinet and the frame. A motor is disposed in the cutter transmission box. A spindle is disposed in the cutter transmission control cabinet parallel with the transmission shaft of the motor. One end of the spindle extends downwardly out of the cutter transmission control cabinet. A connector for cutter connection is fixedly connected to the extended end of the spindle. A transmission device is disposed between the spindle and the transmission shaft of the motor. The numerical control machine tool has the advantages that machining precision can be increased; the moment transmitted by the motor to the spindle is allowed to be stable through gear ratio adjusting.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and relates to a numerically controlled machine tool. Background technique [0002] A CNC machine tool is an automatic machine tool equipped with a program control system. The control system can logically process a program with control codes or other symbolic instructions, decode it, express it in coded numbers, and input it into the CNC device through an information carrier. After calculation and processing, various control signals are sent by the numerical control device to control the operation of the machine tool, and the parts are automatically processed according to the shape and size required by the drawing. CNC machine tools solve complex, precise, small-batch and multi-variety parts processing problems. It is a flexible and high-efficiency automatic machine tool, which represents the development trend of modern machine tool control technology. It is a typical electromechanic...

Problems solved by technology

In the above-mentioned CNC machine tools, the main shaft connected to the tool in the tool transmission control box is generally directly connected to the motor shaft, so that the speed change between the main shaft and the motor shaft cannot be adjusted, and the torque transmitted to the main shaft when the motor is at a low speed cannot meet the processing requirements. , which affects the machining accuracy, making the applicability of CNC machine tools for product processing not strong
