Description

Technical Field

[0001] The invention relates to the technical field of chip removal structures, in particular to a chip removal structure of a mechanical screw of a processing machine tool. Background Art

[0002] The machine tool screw is an important component of chip removal in large machine tools. Large machine tools will generate a large amount of iron chips during the processing, and because the machine tool is relatively large, the screw is needed to assist in smoothly discharging the iron chips inside the machine tool. The original screw installation position is that the screw is installed on the outer shield during operation. During the operation of the screw, the screw will exert force on the outer shield sheet metal, causing the screw running track on the outer shield to deform and wear, thereby causing the deformed machine tool iron chips to be unable to be smoothly discharged from the machine tool.

[0003] According to the patent number CN214489836U, a milling and grinding machine with automatic chip removal is described. When in use, the staff holds the handle with both hands. Under the drive of external force, the guide blocks fixed at both ends of the lower side of the collection box slide on the upper side of the guide rail, and cooperate with the collection box to move along the guide rail until the collection box moves to the bottom of one end of the workbench. At this time, the cleaning mechanism cleans the waste chips on the upper side of the workbench into the collection box, but the operation is cumbersome, and the internal iron chips are prone to friction with the machine tool, causing damage.

The liquid collecting tank below the mesh, the inner cavity of the liquid collecting tank is fixedly connected with a water level sensor, an inner groove is provided on one side of the partition plate, and an electromagnetic switch valve connected to the liquid collecting tank is provided on one side of the inner groove, and the electromagnetic switch valve is electrically connected to the water level sensor. When in use, the cutting fluid with debris falls into the rotating plate above the separation box, and after being filtered through the filter mesh, the cutting fluid falls into the liquid collecting tank below. Then, the rotating plate is tilted at this time, and the debris slides into the lead-out track under the action of gravity and is discharged through the screw. Part of the debris is discharged in the The cutting fluid accumulates in the lead-out track and in the sump in the separation box. When it reaches a certain depth, the water level sensor is triggered. The water level sensor sends a signal to the electromagnetic switch valve, and the electromagnetic switch valve opens. The cutting fluid flows out to the lead-out track under the action of gravity, flushing the screw in the lead-out track and cleaning the adhering debris. The cutting fluid is pressurized by gravity, which can effectively clean the debris adhering to the screw surface without interfering with the normal discharge process. By changing the installation position of the screw, the working efficiency of the screw can be greatly improved. The strength and precision of the machine tool bed are higher than those of the outer cover. The installation process is not easy to deform and wear, which can reduce the failure rate of the machine tool and the qualified rate of product processing. The cutting fluid is pressurized by gravity, which can effectively clean the debris adhering to the screw surface without interfering with the normal discharge process. The screw is installed on the bed. The strength of the bed is higher than that of the outer cover. During movement, it can well offset the force of the screw movement, avoid wear of the screw running track, improve the utilization rate of the screw chip removal, and reduce the failure rate of the machine tool.

[0006] As a further solution of the present invention: the middle section of the rotating plate is configured as a downwardly concave arc surface, and the arc surface increases the area of ​​the filter mesh, making it easier to filter the cutting fluid.

[0007] As a further solution of the present invention: an elastic top plate is fixedly connected to the inner cavity of the liquid collecting tank, the top of the elastic top plate abuts against the bottom of the rotating plate, and the bottom of the rotating plate is supported and buffered by the elastic top plate.

[0008] As a further solution of the present invention: a toggle plate is fixedly connected to the right side of the rotating plate, and when the screw rotates, the surface contacts the toggle plate, and the rotation of the screw drives the toggle plate to move, driving the rotating plate to vibrate, shaking off the debris on the surface and sliding it down, and can effectively filter it.

The support plate supports the end of the screw so that the screw can continue to maintain horizontal rotation, the structure is more stable, and the debris is discharged normally through the guide groove without being affected.

[0010] As a further solution of the present invention: a slag discharge pipe connected to the lowest point of the inner cavity of the liquid collecting tank is provided at the bottom of the separation box. The slag discharge pipe is controlled by an electromagnetic valve, and extremely fine debris accumulated in the liquid collecting tank is discharged through the slag discharge pipe to prevent the electromagnetic switch valve from being blocked.

[0011] During use, the cutting fluid with debris falls into the rotating plate above the separation box, and after being filtered through the filter mesh, the cutting fluid falls into the collecting tank below. At this time, the rotating plate is tilted, and the surface of the screw comes into contact with the toggle plate when it rotates. The rotation of the screw drives the toggle plate to move, driving the rotating plate to vibrate, shaking off the debris on the surface and sliding it down, and it can be effectively filtered. The debris slides into the export track under the action of gravity and is discharged through the screw. Part of the debris accumulates in the export track, and the cutting fluid accumulates in the collecting tank in the separation box. When it reaches a certain depth, it triggers the water level sensor, which triggers the electromagnetic switch valve signal. The electromagnetic switch valve opens, and the cutting fluid flows out to the export track under the action of gravity, flushing the screw in the export track to clean the adhered debris. The cutting fluid is pressurized by gravity, which can effectively clean the debris adhered to the screw surface without interfering with the normal discharging process.
