Description

Technical Field

[0001] The utility model relates to the technical field of drilling machines, in particular to a drilling machine with a circulating cooling function. Background Art

[0002] A drilling machine is a machine tool that mainly uses a drill to make holes on a workpiece. Usually, the rotation of the drill is the main motion, and the axial movement of the drill is the feed motion. The drilling machine has a simple structure and relatively low processing accuracy. It can drill through holes and blind holes. By replacing special tools, it can expand, countersink, ream holes or perform tapping and other processing. During the processing, the workpiece does not move, the tool moves, aligns the center of the tool with the center of the hole, and rotates the tool (main motion). The characteristic of a drilling machine is that the workpiece is fixed and the tool rotates.

[0003] The prior art discloses a drilling machine with a cooling function for a drill bit, with application number: 202222867279.6, comprising: a drilling machine body, which is a CNC drilling machine body, a filter plate is snap-connected at the upper end of the drilling machine body, and a water inlet port of a circulation storage component is snap-connected at the lower end of the drilling machine body, the water outlet of the circulation storage component is connected to the spray component through a pipeline, and the spray end of the spray component is rotatably connected to the limit magnetic plate, the upper end of the limit magnetic plate is snap-connected to the lower end of the control column, and a limit drill bit is arranged at the output end of the control column, and the upper end of the control column is installed inside the upper end of the displacement mechanism. The drilling machine with a cooling function for the drill bit sprays a large area of ​​the position of the limit drill bit through the spray component inside the device. When the spray component is used for spraying, the spray area increased by the whole plate structure of the spray plate improves the rapid cooling of the workpiece and the fingertip position of the limit drill bit, and effectively improves the cooling function of the device during the processing. However, the existing technology still has the problem that the coolant is not cooled down. If the coolant is not cooled down after working for a long time, it is not conducive to the long-term circulation of the coolant, which will reduce the effect of liquid cooling. Therefore, we propose a drilling machine with a circulation cooling function to solve the above problem. Utility Model Content
