Problems solved by technology
[0002] The spindle of a CNC machine tool refers to the axis on the machine tool that drives the workpiece or the tool to rotate. The connection between the spindle of the original CNC vertical drilling machine and the tool body is relatively frictional, and the phenomenon of tool removal is prone to occur during use, causing damage to the machine tool and shortening the service life of the machine tool. On the other hand, in the process of machining and tool changing, iron filings are easy to enter the interior of the spindle and cause damage to the spindle

The invention discloses a tool-changing spindle of a numerically controlled vertical milling machine. An electric drive assembly is provided to drive the rotation of the inner shaft seat; the shaft center of the inner shaft seat is provided with a shaft hole; the lower end of the third drawing shaft is connected with a broach mechanism; The lower ends of each connecting rod are arranged with a locking mechanism; the upper end of the spindle box is equipped with a pneumatic drive assembly. When the present invention is in a compressed state, friction can be reduced and the service life of components can be increased. In the present invention, vent hole 1, vent hole and vent hole 3 are arranged inside pull shaft 1, pull shaft 2, and pull shaft 3, so that injected gas can be discharged from the vent holes, and chamber 1 and chamber 2 are cleaned.
Description
technical field [0001] The invention belongs to the technical field of numerical control, and in particular relates to a tool changing spindle of a numerical control vertical milling machine. Background technique [0002] The spindle of a CNC machine tool refers to the axis on the machine tool that drives the workpiece or the tool to rotate. The connection between the spindle of the original CNC vertical drilling machine and the tool body is relatively frictional, and the phenomenon of tool removal is prone to occur during use, causing damage to the machine tool and shortening the service life of the machine tool. On the other hand, during processing and tool change, iron filings can easily enter the interior of the spindle and cause damage to the spindle. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a tool change spindle of a numerically controlled vertical milling machine, which can realize con...
