A front-end high-efficiency slag removal protection device for the coolant circulation pump of a CNC machine tool

Abstract

The invention relates to the field of numerical control machine tools, and discloses a front-end high-efficiency slag removal protection device for a coolant circulation pump of a numerical control machine tool, which includes a first water inlet pipe, and the water inlet end of the first water inlet pipe is located at the bottom of the coolant water storage tank Above, the water outlet end of the first water inlet pipe communicates with the lower part of the slag removal box, and the first water inlet pipe communicates with the lower part of the slag removal box through a one-way valve, and one end of the one-way valve extends to the slag removal box internal. A liquid outlet hopper with a spiral structure guide plate is installed inside the slag removal box, so that the cooling liquid flowing out of the liquid outlet hopper flows into the centrifugal cavity in a rotating state. Due to the large inner diameter of the centrifugal cavity, the cooling liquid is here The flow velocity at the center decreases, and the heavy metal chips are gradually brought to the inner wall side of the centrifugal chamber, and fall into the bottom of the slag removal box along the gap between the inner wall of the cone and the outer wall of the liquid outlet hopper under the action of its own weight. , so as to realize the separation of metal chips.

Description

technical field [0001] The invention relates to the field of air traffic control radar, in particular to a front-end high-efficiency slag removal protection device for a coolant circulation pump of a numerical control machine tool. Background technique [0002] CNC machine tools are equipped with a cooling circulation system, which pumps the coolant into the center hole at the front of the machine head through the circulation pump to cool the tool, and then the coolant is collected and returned through the collection tank on the machine. Finally, it flows back to the circulating pump through the pipeline to complete the cycle. [0003] During the processing of metal by CNC machine tools, some fine metal chips will flow to the cooling water tank with the cooling liquid. The rotating impeller collides, which damages the impeller and blocks the internal passage of the circulation pump. [0004] According to the technical solution provided by the patent document CN208409371U, ...
