Description

Technical Field

[0001] This utility model belongs to the field of CNC machining centers, specifically relating to an automatic chip removal structure for the tool magazine protection structure of a vertical machining center. Background Technology

[0002] Existing vertical machining centers are usually equipped with disc-type tool magazines. To prevent chips and cutting fluid from affecting the tool magazine during machining, a tool magazine protection structure is often designed to protect the tool magazine and improve its reliability.

[0003] Because the tool magazine's protective structure has a pre-drilled tool-changing slot, allowing tools of a certain length to rotate and pass through, it facilitates the tool-grabbing, pulling, and inserting actions of the tool-changing arm. Chips easily accumulate at this slot. While installing two rows of opposing brushes at the slot can help prevent chips from entering the tool magazine's protective structure, it doesn't completely eliminate the possibility of chips entering through the slot. Furthermore, with prolonged use, the brushes tend to deform and sag, reducing their chip-prevention effectiveness. Utility Model Content

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an automatic chip flushing structure for the tool magazine protection structure of a vertical machining center. The automatic chip flushing structure includes a water tank, a flushing pipe, and a nozzle. The water tank is connected to the flushing pipe via a water pump and a connector. The nozzle is installed on the flushing pipe. The flushing pipe is fixed to the tool magazine protection structure of the vertical machining center. The tool magazine protection structure includes an integral protective cover and a bottom protective plate. The bottom protective plate is inclined and located on the lower side of the disc-type tool magazine of the vertical machining center. The protective cover is connected to the side of the bottom protective plate. A chip discharge port is opened on the front side plate of the protective cover. The chip discharge port communicates with the internal space of the protective cover. The chip discharge port is located on the lower side of the lower part of the bottom protective plate. The nozzle is located on the upper side of the higher part of the bottom protective plate and faces the lower part of the bottom protective plate. A tool changing port is opened on the bottom protective plate. Two rows of brushes are installed at the tool changing port.

[0006] This utility model's automatic chip removal structure automatically removes chips. Cutting fluid is sprayed from nozzles, pushing the chips that fall onto the bottom protective plate and brush towards the lower part of the bottom protective plate. Finally, the chips and cutting fluid are discharged from the chip removal port into the protective cover, effectively protecting the disc-type tool magazine, improving its service life and reliability, and meeting the needs of automated production. During workpiece machining in a vertical machining center, the brush prevents most chips from entering the tool magazine's protective structure from the tool changer. Furthermore, because the chips falling on the brush are promptly washed away by the cutting fluid, they do not accumulate on the brush, effectively extending its service life and ensuring its chip-removing effect. Chips accumulated inside the protective cover can be cleaned periodically by personnel.

[0007] Preferably, a protective door is installed on the front panel of the protective cover, located in front of the chip discharge port. When it is necessary to clean the chips accumulated inside the protective cover, personnel can easily perform the corresponding operation by opening the protective door.

[0008] Preferably, the flushing pipe is welded to the protective cover, and the flushing pipe is located on the upper side of the high part of the bottom protective plate.

[0009] Preferably, the number of nozzles is multiple, and the multiple nozzles are arranged at intervals along the length of the flushing pipe.

[0010] Preferably, the bottom protective plate is made of stainless steel to reduce friction with the chips, which helps the chips to be smoothly flushed to the chip discharge port and ensures the chip flushing effect.

[0011] Compared with existing technologies, this utility model has the following advantages: The automatic chip flushing structure of the vertical machining center tool magazine protective structure of this utility model can automatically flush chips, pushing the chips falling on the bottom protective plate and brush towards the lower part of the bottom protective plate. Finally, the chips and cutting fluid are discharged from the chip discharge port into the protective cover, effectively protecting the disc-type tool magazine, improving its service life and reliability, and meeting the needs of automated production. Furthermore, during the machining process of the vertical machining center, the brush can prevent most of the chips from entering the tool magazine protective structure from the tool changer. Since the chips falling on the brush can be promptly flushed away by the cutting fluid, the chips will not accumulate on the brush, thus effectively extending the brush's service life and ensuring its chip-prevention effect.
