[0002] Composite parts are usually processed by electric spindles during milling, drilling and cutting. The contact between the electric spindle tool and the composite material will generate a lot of dust and debris. The dust and debris will penetrate into the machine, causing damage to precision components and shortening the machine life. At the same time, a lot of dust entering the air will make the working environment harsh and endanger the respiratory health of operators. Therefore, it is necessary to collect the dust and debris generated during the cutting process of the electric spindle tool.

[0003] At present, in order to solve the problem of dust and debris, a dust hood is generally fixed on the electric spindle, which is connected to the vacuum cleaner through a PU air duct to discharge dust and debris. In the prior art, the dust hood is mostly welded on the electric spindle in an integrated structure, but if the dust hood is damaged, it cannot be repaired and needs to be scrapped as a whole, which has high cost of use; some prior art also fixes the side of the electric spindle close to the tool direction by means of a clamp, but during use, it is easy to break due to the structural strength, and the tightness and effective time are difficult to guarantee. In addition, due to the vibration of the tool, the dust hood may rotate due to the looseness of the clamp, causing the dust hood to collide with other mechanisms, resulting in unnecessary economic losses.
