Under negative pressure, the debris passes through the protective net 34 and enters the interior of the dust box 3, and then enters the interior of the waste box 13 through the collection pipe 1 31 and the collection pipe 2 32 to be collected by the cleaning drawer 14. When the storage cross bar 21 rotates to a certain angle, the side of the dust box 3 tilts downward under the action of gravity, and the debris will enter the interior of the waste box 13 through the collection pipe 3 33, so that the debris can be collected quickly and timely, waste accumulation can be avoided, and machining can be ensured. The efficiency of the work is improved and the wear of the device is reduced. The collecting pipe 1 31, the collecting pipe 2 32 and the collecting pipe 3 33 are symmetrically arranged about the center line of the storage cross bar 21. The collecting pipe 1 31, the collecting pipe 2 32 and the collecting pipe 3 33 symmetrically arranged on the center line can comprehensively collect the debris. The collecting pipe 1 31 and the collecting pipe 2 32 transport the debris at the bottom of the dust box 3 to the inside of the waste box 13, and the collecting pipe 3 33 transports the debris on the side of the dust box 3 into the inside of the waste box 13, thereby ensuring the efficiency and effect of debris collection. The cleaning drawer 14 is provided with a slide groove near the turntable base 1, and the cleaning drawer 14 and the turntable base 1 are engaged with a sliding installation structure through the slide groove, and the slide groove can be used for The sliding of the cleaning drawer 14 is guided and limited, which is convenient for taking out the cleaning drawer 14, and then it is convenient for the subsequent processing of debris. The protective net 34 adopts a mesh setting. The mesh setting of the protective net 34 can block the workpiece to prevent the workpiece or other large particles from falling into the dust box 3 and prevent the collection pipe 1 31 from being blocked. The collection pipe 3 33 and the dust box 3 are connected and fixed by a flange. The flange can make the connection between the collection pipe 3 33 and the dust box 3 more firm and reliable, thereby ensuring the airtightness of the connection between the collection pipe 3 33 and the dust box 3. The dust box 3 is symmetrically provided with two about the center line of the storage cross bar 21, and the dust box 3 is fixed to the storage cross bar 21 by bolts.The dust box 3 is firmly installed on the outside of the storage cross bar 21 by bolts, which can make the installation of the dust box 3 more reliable and firm, and facilitate the collection of debris by the dust box 3.

The parallel arrangement of the axis can make the rotation of the rotating shaft 2 more reliable and stable. The connection between the workbench 24 and the storage cross bar 21 is equipped with a bearing. The rotating shaft 2 rotates under the drive of the servo motor 22 and the planetary gear reducer 23. The bearing at the connection between the workbench 24 and the storage cross bar 21 can effectively reduce the friction when the workbench 24 rotates.

[0035] The working principle of the utility model is as follows: when using the device, the device is installed in the machining center.

The servo motor 22 can drive the workbench 24 to rotate through the planetary gear reducer 23. The position of the workpiece can be adjusted in the above manner. When the tool is cut, the debris splashes outward. During the splashing process, the exhaust pipe 15 draws the waste box 13 into a vacuum state. Under the negative pressure state, the debris passes through the protective net 34 and enters the interior of the dust box 3, and then passes through the collection pipe The channel 1 31 and the collection pipe 2 32 enter the interior of the waste box 13 and are collected by the cleaning drawer 14. After the collection is completed, the cleaning drawer 14 can be pulled to take out the waste. When the storage cross bar 21 is rotated to a certain angle, the debris passes through the protective net 34 under the action of gravity and enters the interior of the dust collecting box 3. At this time, the side of the dust collecting box 3 is tilted downward, and the debris will enter the interior of the waste box 13 through the collection pipe 3 33. This method can effectively ensure the collection of debris, quickly and timely collect debris, avoid waste accumulation, ensure machining efficiency, and reduce wear of the device.
