Cutter head cooling device with tool rest water outlet capable of being rotated at will

Abstract

The invention belongs to the field of numerically-controlled machine tools, and particularly provides a cutter head cooling device with a tool rest water outlet capable of being rotated at will. The cutter head cooling device aims to solve the problems that a tool rest water outlet in the prior art cannot be rotated, and the connecting structure of a cutter head water inlet hole and the tool rest water outlet is complex. The cutter head cooling device comprises a first cooling channel formed in a cutter head, a second cooling channel formed in a tool rest, and a rotating disk arranged on the tool rest. The cutter head is installed on the tool rest in a rotatable mode. The rotating disk is provided with a through hole. A connecting ring capable of sliding in the axial direction is arranged in the through hole. The connecting ring can communicate with the first cooling channel and the second cooling channel. According to the cutter head cooling device, axial sliding of the connecting ring replaces axial movement of the cutter head, so that the structure is made simpler; and moreover, due to the arrangement of the rotating disk, the cutter head can communicate with the first cooling channel and the second cooling channel when being rotated to any position, and the cutter head can be cooled.

Description

technical field [0001] The invention belongs to the field of numerically controlled machine tools, and specifically provides a cutter head cooling device in which a water outlet of a cutter holder can be rotated arbitrarily. Background technique [0002] When the machine tool is processing the workpiece, the friction and cutting between the workpiece and the tool will cause a certain temperature rise to the tool, especially when the hardness of the workpiece is too large and the tool is fast-moving, it will often cause a large temperature rise of the tool and affect the tool. Life, therefore, requires cooling of the tool. At present, it is generally used to cool the cutter head and then cool the cutter head, directly cool the cutter head or simultaneously cool the cutter head and the cutter head. When cooling the cutter head, generally a water pipe is arranged on the cutter head, and the water pipe is connected to the water inlet hole of the cutter head, and then cooling li...
