Description

Technical Field

[0001] The utility model relates to the technical field of water tanks for numerically controlled machine tools, in particular to a water tank for circulating cutting fluid for numerically controlled machine tools. Background Art

[0002] The cutting fluid tank of CNC machine tools is mainly used to store and circulate cutting fluid to effectively cool the heat generated during the machining process. In order to reduce the waste of circulating fluid, most manufacturers will use cutting fluid storage tanks to store the circulating fluid, and filter the circulating fluid in the tank before injecting it into the CNC machine tool to participate in the work.

[0003] Waste chips are generated during the operation of traditional machine tools. After the waste chips are discharged from the machine tool along with the cutting fluid, they are concentrated in the water tank. At this time, a large amount of metal waste chips are mixed with the cutting fluid in the water tank. In order to facilitate the separation of metal waste chips, some water tanks are provided with a filtering structure to intercept metal waste chips. The water tank filtering structure in the prior art is generally an ordinary mesh plate or a metal filter. The disassembly and cleaning method of the filtering structure is not convenient, which can easily cause the water tank filter to be blocked or the waste chips to accumulate above the filter. Utility Model Content

The edge is bent outward to form a water tank upper edge 101, and the upper front edge and rear edge of the water tank upper edge 101 are rotatably connected to the upper edge roller 102. The axis of the upper edge roller 102 is perpendicular to the front wall of the water tank body 1. The recovery bucket 2 is a bucket-shaped structure set toward the middle. The outer edge of the recovery bucket 2 is fixedly connected to the outer edge 201 of the bucket, and the lower surface of the outer edge 201 of the bucket is rollingly connected to the upper edge roller 102; the rolling connection between the outer edge 201 of the bucket and the upper edge roller 102 reduces the moving resistance of the recovery bucket 2 and reduces the noise during the reciprocating shaking of the recovery bucket 2. The recovery bucket 2 set with the middle settlement can concentrate the cutting fluid and metal waste entering the water tank body 1.

[0030] In the embodiment of the present disclosure, the lower edge of the inner wall of the filter cartridge mounting cylinder 203 is provided with a limiting inner edge 204, the cylinder wall and the cylinder bottom of the chip filter cartridge 3 are both made of steel mesh plates, the upper edge of the chip filter cartridge 3 is fixedly connected to the filter cartridge docking ring 301, and the upper part of the filter cartridge docking ring 301 is fixedly connected to the filter cartridge handle 302, and the lower edge of the filter cartridge docking ring 301 is in contact with the limiting inner edge 204, which plays a limiting role to prevent the chip filter cartridge 3 from falling from the inside of the filter cartridge mounting cylinder 203. The cylinder wall and the cylinder bottom of the chip filter cartridge 3 are both made of steel mesh plates, which can intercept the cutting waste entering the interior of the chip filter cartridge 3, and prevent the cutting waste from passing through the cylinder wall of the chip filter cartridge 3 and entering the water tank body 1 to affect the purity of the cutting fluid.

[0031] Example 2. On the basis of Example 1, a circular circulation push plate 303 is fixedly connected to the center of the lower surface of the chip filter barrel 3, and a translation push groove 304 is opened on the lower surface of the circulation push plate 303.

During the rotation of the active rotary disk 5, the active plug shaft 501 rotates around the axis of the active rotary disk 5. The active plug shaft 501 slides back and forth inside the translation push groove 304, and at the same time pushes the chip filter barrel 3 to move left and right, driving the recovery bucket 2 and the chip filter barrel 3 to move back and forth as a whole, so that the metal waste accumulated above the recovery bucket 2 falls along the inclined surface to the inside of the chip filter barrel 3 for collection.

[0032] The working principle of this embodiment is as follows: before cleaning the chip filter barrel 3, the circulation drive member 4 is started, and the circulation drive member 4 drives the active rotary disk 5 to rotate. During the rotation of the active rotary disk 5, the active plug shaft 501 rotates with the axis of the active rotary disk 5 as the center, and the active plug shaft 501 slides back and forth inside the translation push groove 304, while pushing the chip filter barrel 3 to move left and right, driving the recovery bucket 2 and the chip filter barrel 3 to move back and forth as a whole, so that the metal waste accumulated above the recovery bucket 2 falls along the inclined surface to the inside of the chip filter barrel 3 for collection. After closing the circulation drive member 4, the filter barrel handle 302 is fixed by a tool and pulled upward, the chip filter barrel 3 is taken out from the recovery bucket 2 and the internal metal waste is cleaned, and the cleaning work of the water tank body 1 is completed.
