High-efficiency numerically-controlled machine tool

Abstract

The invention discloses a high-efficiency numerically-controlled machine tool which comprises a rack, a driving device, and a numerical control device positioned on one side of the rack. The driving device moves under the control of the numerical control device; a fixing clamp is arranged on the rack; a knife rest is arranged above the rack; a servo motor and a plurality of different types of cutters in regular arrangement are arranged on the knife rest; the cutters are connected with a first cylinder by virtue of a connecting rod provide with a long and narrow groove; a metal sleeve shorter than the connecting rod is movably arranged outside the connecting rod in a sleeving manner; the metal sleeve is provided with a notch which corresponds to the groove; a clamping piece is mounted in the notch, is embedded into the groove and slides up and down along the groove; a driving wheel is fixedly arranged on the outer surface of the metal sleeve in a sleeving manner; a plurality of driving wheels outside the connecting rod are connected with the servo motor by virtue of the same driving belt. According to the numerical control device, a tool can be controlled to be close to a to-be-processed product, the original working tool is controlled to restore the original position, two control instructions do not influence each other, and a high-speed rotating state is not changed.

Description

Technical field [0001] The invention relates to a numerically controlled machine tool, in particular to a numerically controlled machine tool capable of realizing high efficiency. Background technique [0002] CNC machine tool is the abbreviation of digital control machine tool, which is an automatic machine tool equipped with a program control system. The control system can logically process a program with a control code or other symbolic instructions, decode it, express it with coded numbers, and input it into the numerical control device through an information carrier. After arithmetic processing, the numerical control device sends out various control signals to control the action of the machine tool, and automatically process the parts according to the shape and size required by the drawing. The CNC machine tool has solved the problems of complex, precise, batch, and multi-variety parts processing. It is a flexible and high-performance automatic machine tool. It represents t...

Problems solved by technology

[0005] The overall size of the above two tool change devices is relatively large, the structure is more complicated, the tool change time is longer, and the efficiency is not high, which will also affect the working efficiency of the entire CNC machine tool

Moreover, these two tool changing devices are basically only for large-scale CNC machine tools, and the cost is quite high, and ordinary small enterprises cannot afford them.
