Abstract

The invention discloses a numerical control machine tool main shaft structure and belongs to the technical field of numerical control machine tools. The numerical control machine tool main shaft structure comprises a main shaft box, the main shaft box is provided with a main shaft, and the main shaft rotates relative to the main shaft box; the end above the main shaft is provided with a columnar fluid outlet head and connected with the bottom of the fluid outlet head, and the top of the fluid outlet head is connected with a knife beating assembly; the center of the main shaft is provided with a channel, the center of the fluid outlet head is provided with a fluid outlet channel, the side wall is provided with a fluid outlet, and the fluid outlet is communicated with the fluid outlet channel; cooling fluid reaches the fluid outlet channel of the fluid outlet head through the channel in the center of the main shaft and is released from the fluid outlet in the side wall. By means of the numerical control machine tool main shaft structure, the effects of automatic cooling and lubricating in the processing process of the main shaft structure are achieved.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a spindle structure of a numerical control machine tool. Background technique [0002] The main shaft is one of the important parts of the CNC machine tool. The processing tool is usually installed on the main shaft, and the main shaft drives the tool to process the product. The quality and maximum speed of the main shaft have a great influence on the processed product. [0003] Existing spindles are often accompanied by heat generation during high-speed machining or deep hole machining. The heating of the spindle will affect the machining accuracy, and even cause the spindle or tool to be burned out in serious cases. Contents of the invention [0004] In view of the above problems, the present invention provides a CNC machine tool spindle structure, which is provided with a cooling and lubricating structure for the spindle, which is used to cool and lu...
