Description

Technical Field

[0001] The utility model relates to the technical field of tool protection devices, in particular to a tool protection device used in a machining center. Background Art

[0002] Machining center is a mechanical equipment commonly used by manufacturers and can realize various types of processing. When working, the machining center will change tools as needed to facilitate processing. The replaceable machining tools can be prevented from being on the tool holder through the program to realize automatic tool change.

[0003] During machine tool processing, the cutter head rotates at high speed and rubs against the workpiece. The mutual friction increases the temperature of the cutter head. Excessive cutter head temperature will affect the physical properties of the cutter head, which is not conducive to the processing of the machining center. The existing cutter head cooling device has a relatively simple structure, and the angle of the cooling water nozzle cannot be adjusted. The coolant can often only be sprayed on the cutter head, resulting in the root of the cutter head being unable to cool, increasing the risk of tool breakage. At the same time, a large amount of debris will be generated during processing. These debris will splash everywhere, and when the tool is replaced, the debris on the tool cannot be cleaned in time. Therefore, it is urgent to design a tool protection device for a machining center to solve the above problems. Utility Model Content
