Description

Technical Field

[0001] The utility model relates to a cooling device for machine tool cutters, belonging to the technical field of machine tool cutters. Background Technique

[0002] Machine tool cutters are essential tools in the machine tool processing process and are one of the main means to achieve workpiece processing. There are various types of machine tool cutters, and different types of cutters are suitable for different processing technologies and materials. The function of machine tool cutters is to cut, trim and process workpieces, specifically including turning, milling, drilling, grooving and other functions. By selecting appropriate machine tool cutters, different types of processing requirements can be achieved, thereby improving production efficiency and product quality.

[0003] There is a cooling device for machine tool cutters with the patent number CN220296594U. Through the coordinated use of structures such as a protective cover, installation groove, spring, limit block, push rod, extension cover, and nozzle, this device can cool the cutter by water cooling, preventing the cutter from deforming, thus having a relatively high service life, preventing debris from splashing, and keeping the working environment clean. However, this device cannot switch the orientation of the nozzle during use. Existing machine tool milling cutters are usually fed horizontally during use. When moving in different directions, one end face of the cutter fits the workpiece for processing, and it is difficult for the nozzle to spray cooling water on the fitting surface, while the exposed surface cannot be directly sprayed with water for cooling, thus affecting the use effect of water cooling; moreover, the sizes and types of machine tool cutters are diverse. Therefore, it is difficult to accurately spray the processing area of the cutter when only using a single type of fixed nozzle to spray cooling water, further reducing the spraying effect.
