Description

Technical Field

[0001] The utility model relates to the field of a turret tool seat, in particular to a turret tool seat with an automatic switching function. Background Art

[0002] The turret toolholder is a metalworking machine tool used to process precise circular and cylindrical workpieces. The turret toolholder processes the workpiece by rotating the workpiece and moving the tool at the same time. The tool can be automatically changed by rotating the turret toolholder, so it has efficient and precise processing capabilities.

[0003] When the tool on the turret tool holder processes the workpiece, high temperature will be generated due to the friction between the tool and the workpiece, so coolant is needed to cool the tool. When using coolant to cool the tool, the coolant is usually sprayed by connecting bellows and nozzles. The connecting bellows can be deformed to change the working position of the nozzle. However, when the machine tool is working, its interior is in a relatively closed environment. When the turret tool holder moves, it will be misaligned with the coolant sprayed by the nozzle, making it inconvenient for the nozzle to move synchronously with the turret tool holder.
