Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that when the spindle tool is working, the torsional loss is very serious, it is easy to generate heat, the processed product is easy to deform, and there are large defects
However, the existing cooling device generally uses an external blowing coolant pipe to align the tool with flushing to achieve the purpose of cooling and cooling. However, it is necessary to straighten the air blowing pipe and water blowing pipe, and it is easy to deviate from the main axis during operation. , resulting in poor cooling effect

Abstract

The invention relates to the field of numerical control machine tools, in particular to a numerical control engraving and milling machine. The numerical control engraving and milling machine comprises a spindle box, a vertically-arranged spindle is rotationally connected into the spindle box, a cutter is installed at the lower end of the spindle, a ring sleeve sleeving on the outer side of the spindle and rotationally connected to the spindle is arranged in the spindle box, liquid outlet cavities surrounding the spindle are formed in the ring sleeve, the spindle box is provided with a driving mechanism capable of driving the spindle and the ring sleeve to rotate at different rotating speeds, a plurality of liquid spraying pipes with nozzles facing the cutter are arranged on the lower side of the ring sleeve around the main shaft, and a liquid feeding pipes are connected between the liquid outlet cavities of the ring sleeve and the liquid spraying pipes. The numerical control engraving and milling machine has the advantages that the relative position of cooling liquid pipes and a tool bit is guaranteed, and the cooling effect is improved.

Description

technical field [0001] The present application relates to the field of numerical control machine tools, in particular to a numerical control engraving and milling machine. Background technique [0002] CNC engraving and milling machine is a kind of CNC machine tool. It is a CNC machine tool corresponding to the traditional engraving machine. CNC engraving and milling machines are generally CNC milling machines that use small tools, high power, and high-speed spindle motors. The engraving and milling machine can be used for both engraving and milling. On the basis of the engraving machine, the power of the main shaft and servo motor is increased, and the bed bears the load, while maintaining the high speed of the main shaft, and more importantly, high precision. It is a high-efficiency and high-precision CNC machine tool. [0003] Existing reference can be made to the Chinese invention patent whose application publication number is CN102773529A, which discloses an engravin...
