Description

Technical Field

[0001] The present application belongs to the technical field of numerical control machining, and relates to a filtering mechanism for a numerical control machining center which is easy to clean. Background Art

[0002] With the continuous development of domestic CNC technology, the chip removal and filtration device, as an independent accessory device on CNC machining centers, has attracted more and more attention for its performance. The key performances such as chip removal efficiency, filtration accuracy, and practicality directly affect customers' evaluation of a CNC machining center.

[0003] Patent CN112676905B discloses a chip removal and coolant recovery filtration system for CNC machine tools. Through reciprocating double filtration, the coolant is effectively purified and pure coolant is output. At the same time, the metal debris in the double filtration mechanism is accumulated on the coarse filter. As the debris on the coarse filter increases, the filtration effect of the coarse filter is effectively enhanced, thereby making the separation of debris and coolant faster.

[0004] After being used for a period of time, the filter needs to be cleaned to avoid clogging. The filter of existing CNC machine tools is inconvenient to remove, resulting in poor cleaning convenience. Utility Model Content

[0005] In order to improve the convenience of cleaning the filtering mechanism, the present application provides a filtering mechanism for a CNC machining center that is easy to clean.

[0006] The present application provides a CNC machining center filter mechanism that is easy to clean and adopts the following technical solution:

[0008] By adopting the above technical solution, the cooling waste liquid, metal waste chips, etc. generated during the operation of the CNC machining center can flow into the chassis, and flow into the receiving box through the chip discharge port and the chip discharge plate. The cooling waste liquid flows into the water tank through the filter, and the waste chips remain on the filter. When the filter needs to be cleaned, the operator can take out the receiving box by the handle for cleaning, which is convenient and quick, thereby improving the cleaning convenience of the filtering mechanism.

[0009] Preferably, the filtering mechanism further comprises a filter box, which is arranged at the bottom of the receiving box, the bottom of the filter box has an opening aligned with the filter screen, the side wall of the filter box is provided with a handle, and the suspended end of the chip removal plate extends into the filter box.

[0010] By adopting the above technical solution, after the filter box is provided, the cooling waste liquid and metal waste chips can be gathered above the filter screen, reducing the possibility of outflow to the corners of the receiving box, improving the filtration efficiency, and providing a handle to facilitate the removal and cleaning of the filter box.

[0011] Preferably, two through holes are provided at intervals at the bottom of the receiving box along the length direction of the receiving box, the filter screen covers the two through holes, and the opening of the filter box is aligned with the through hole close to the chip removal plate.

[0012] By adopting the above technical solution, when the liquid level of the cooling waste liquid in the filter box is too high, the cooling waste liquid can flow out of the filter box and be filtered through the filter screen at another through hole.

[0013] Preferably, the water tank is rectangular, and the upper ends of the two long side walls of the water tank are bent to form an "L"-shaped fold, and the bottom of the material receiving box is placed on the "L"-shaped fold.

[0014] By adopting the above technical solution, the "L"-shaped folded edge can support the receiving box and play a limiting role at the same time, thereby preventing the receiving box from moving significantly in the width direction.

[0015] Preferably, the upper ends of the two side walls in the length direction of the receiving box are bent to form a slide groove, and the notch of the slide groove faces downward.

[0016] By adopting the above technical solution, a slide groove is provided above the side wall of the receiving box. When taking out the receiving box, a corresponding support bar can be placed on the side. The slide groove cooperates with the support bar to facilitate taking out the receiving box and improve the convenience of cleaning.

[0017] Preferably, a mounting seat is provided at the chip discharge port, and a chip discharge cover is hingedly connected to the mounting seat. When the chip discharge cover is in a horizontal state, it can cover the chip discharge plate and align with the opening of the filter box; when the chip discharge cover is flipped upward to a vertical state, it can be removed from the material receiving box.

[0018] By adopting the above technical solution, when the CNC machining center is running, the chip cover is in a horizontal state, reducing the risk of waste liquid and waste chips splashing outside the filter box. When cleaning is required, the chip cover is flipped to a vertical state and removed from the receiving box, making it easy to take out the receiving box.

[0019] Preferably, a limit plate is provided on the side wall of the chip removal cover, and when the limit plate is in contact with the mounting seat, the chip removal cover is in a horizontal state.

[0020] By adopting the above technical solution, the chip removal cover can maintain a horizontal state under the action of gravity through the limiting plate.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. When the filter needs to be cleaned, the operator can take out the material receiving box by the handle for cleaning, which is convenient and quick, and improves the convenience of cleaning the filter mechanism;

[0023] 2. After the filter box is installed, the cooling waste liquid and metal waste chips can be gathered above the filter screen, reducing the possibility of outflow to the corners of the receiving box, improving the filtering efficiency, and a handle is provided to facilitate the removal and cleaning of the filter box.
