Description

Technical Field

[0001] The utility model relates to the technical field of CNC machining, in particular to a metal chip removal device for a CNC machining center. Background Art

[0002] A CNC machining center is a high-efficiency automated machine tool composed of mechanical equipment and a CNC system suitable for machining complex parts. When a workpiece is processed in a CNC machining center, some waste chips will be generated regardless of whether the workpiece is cut or drilled. If these waste chips are not discharged from the machine tool in time, the processing of the workpiece will be affected. For example, as shown in a new type of CNC machining center with a debris cleaning function with Chinese patent application number CN202123287752.5, most of the debris generated by the machine tool processing falls on the material plate in the discharge port, and the inclined plates on both sides of the material plate make the debris slide forward. When the rotating shafts on both sides rotate clockwise in the machine tool through the bearings, the material plate rotates clockwise in the discharge port, and the debris can be poured out through the inclined port, without the need to manually clean the debris in the discharge port.

[0003] However, since the rotating shafts used all rotate clockwise in the machine tool through bearings, the material plate rotates clockwise in the discharge port, and the waste chips can be automatically poured out through the oblique port. However, the waste chips cannot be separated from the cutting fluid during chip transportation, which is not conducive to the recycling of the cutting fluid and causes a waste of resources. Utility Model Content

[0004] In order to solve the problem that the waste chips and cutting fluid cannot be separated during the waste chip transportation, which is not conducive to the recycling of the cutting fluid and causes waste of resources, the utility model provides the following technical solutions:

[0006] The chip removal device comprises a chip removal assembly arranged in a slag removal box for filtering metal debris, and a driving assembly for driving the chip removal assembly to vibrate up and down is arranged above the chip removal assembly.

[0007] Furthermore, a slag discharge port is provided at the top of the slag discharge box for discharging metal scraps generated by machining the processing device body into the slag discharge box, and a liquid storage chamber for collecting coolant is provided in the box cavity of the slag discharge box.

[0008] Furthermore, the chip removal assembly includes a filter plate arranged in the slag removal box for up and down vibration, a connecting plate is fixedly installed at the bottom end of the filter plate, and a spring for driving the connecting plate to vibrate up and down is fixedly installed at the bottom end of the connecting plate.

[0009] Furthermore, the driving assembly includes a rotating shaft arranged at the front end of the slag discharge box for rotation, a motor for driving the rotating shaft to rotate is fixedly installed at the front end of the rotating shaft, and a cam for cooperating with a spring to drive the connecting plate to perform intermittent vibration is arranged on the shaft body of the rotating shaft.

[0010] Furthermore, a support leg for supporting the slag discharge box is fixedly installed at the bottom end of the slag discharge box, and there are four support legs, which are distributed in a rectangular array at the four corners of the bottom end of the slag discharge box.

[0011] Furthermore, a slag storage box for collecting metal scraps is provided in the slag discharge box, and a drain pipe for discharging the coolant in the liquid storage cavity is provided at the front end of the slag discharge box.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] By arranging a chip removal device, when it is necessary to filter metal debris and coolant for reuse, the motor can be used to drive the rotating shaft to rotate, which can drive the cam and the connecting plate to vibrate up and down intermittently under the elastic action of the spring, so that the metal debris on the filter plate can be quickly collected along the filter plate into the slag storage box, and the coolant can be retained in the liquid storage cavity and finally discharged through the drain pipe, thereby realizing the reuse of the coolant.
