Description

Technical Field

[0001] The utility model relates to the technical field of cooling of numerical control machining centers, in particular to an adjustable cooling device for numerical control machining centers. Background Art

[0002] CNC machining centers are highly efficient automated machine tools that are composed of mechanical equipment and CNC systems and are suitable for machining complex parts. They are also one of the most productive and widely used CNC machine tools in the world. The tool magazine is where the tools are stored in the CNC machining center. When the CNC machining center processes parts, it needs to select the appropriate tool through the automatic tool changer. The tool rotates at high speed when working, generating a lot of heat. A cooling device is needed to cool the tool head to ensure the safety of the device and extend the service life of the tool.

[0003] Announcement No. "CN213730750U" provides a cooling device for a CNC machining center, which can install a spray cylinder and a drive casing, and has good anti-falling and anti-swaying effects. The flexible installation method also facilitates subsequent disassembly, and the position of the spray cylinder on the surface of the mounting frame can be freely adjusted, so that when inspecting and replacing the spray cylinder, it can be kept away from the drive casing and processing tools, thereby expanding the operating space, saving time and effort, and the position of the spray metal pipe can be adjusted, which makes the cooling work more flexible and adaptable to different application scenarios.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] Since the CNC machining center needs to replace machining tools of different lengths during actual use, the height of the spray metal tube needs to be matched and adjusted after the machining tool is replaced. Although the position of the spray metal tube in the cooling device of the CNC machining center can be adjusted, in the process of adjusting the height of the spray metal tube, the installation mechanism needs to be disassembled first, and then the height of the spray metal tube can be matched and adjusted. After the adjustment is completed, the installation mechanism can be installed. This adjustment method is time-consuming and labor-intensive, which affects the machining efficiency of the CNC machining center and is not practical. Utility Model Content
