The phenomenon that beat of clamp precision decline, cutter that collet occur increases.
A kind of collet with dustproof construction disclosed by the utility model, including the collet sheet being mounted in high-speed electric main shaft
Body, the front end of Gripper body are provided with several in the circumferential equally distributed lobe for clamp-on tool, between adjacent lobe
Valve slot is formed, the front end of each valve slot is provided with the counterbore extended in a radial direction, the shape on the lobe at counterbore
At groove, it interference fit is embedded with rubber plug in each counterbore, groove is close to the outer wall of rubber plug, the inner end and knife of rubber plug
There are gaps between the outer wall of tool.
An embodiment according to the present utility model is provided with boss on the outer end face of rubber plug.
An embodiment according to the present utility model is provided with and can be cooperated with the inner wall of groove on the outer wall of rubber plug inner end
Guiding is to facilitate rubber plug to be embedded into the annular guide surface in counterbore.
An embodiment according to the present utility model is provided with and can be cooperated with the outer wall of rubber plug on the inner wall of groove outer end
Guiding is to facilitate rubber plug to be embedded into the arcwall face in counterbore.
The utility model is by the setting of rubber plug, and rubber plug can stop dust and chip, so as to effectively keep away
Exempt from dust and chip to enter inside collet and electro spindle by valve slot, so, can be avoided collet and stuck show occur
As, and can be avoided because dust enters collet occur collet clamp precision decline, cutter beat increase the phenomenon that.
