Abstract
Description
Technical Field
[0001] The utility model relates to the field of numerical control machine tool structures, in particular to a debris cleaning mechanism of a numerical control machine tool. Background Art
[0002] CNC machine tools are a commonly used processing equipment. They are mainly used for cutting inner and outer cylindrical surfaces of shaft parts or disk parts, inner and outer conical surfaces of arbitrary taper angles, complex rotational inner and outer curved surfaces, and cylindrical and conical threads. They can also perform grooving, drilling, reaming, reaming and boring, etc.
[0003] The CNC machine tool automatically processes the processed parts according to a pre-compiled processing program. Its structure roughly includes a processing table, a cutting mechanism and a CNC mechanism. The existing CNC machine tools will leave a lot of debris in the CNC machine tool box after processing. In the prior art, it is necessary to clean these debris. The ordinary way is to use people to clean them manually. However, since a processing table is set in the box, manual cleaning is very cumbersome and inconvenient. Therefore, in response to this situation, improvements have been made in the prior art. A chip cleaning mechanism is set in the box of the CNC machine tool, just like the patent with application number "CN202020657994.5", in which a blowing mechanism is set on both sides of the processing box for chip cleaning. However, as the applicant stated, a workbench is set in the existing CNC machine tool. In this way, some debris will be blocked by the side walls of the workbench when blowing against each other and cannot be cleared out. Therefore, the existing chip cleaning mechanism cannot clean the debris in the box of the CNC machine tool. In response to the above-mentioned defects, the present application improves the chip cleaning mechanism of the CNC machine tool. Summary of the invention
[0004] The utility model aims to provide a chip cleaning mechanism for a numerically controlled machine tool, so as to solve the problem that the existing chip cleaning mechanism cannot clean thoroughly because a processing table is arranged in the chassis of the existing numerically controlled machine tool.
[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0006] A chip cleaning mechanism for a numerically controlled machine tool comprises a flip chip removal table and a chip cleaning mechanism at the bottom of the table, wherein the flip chip removal table is arranged on the top of a worktable of the numerically controlled machine tool, one side of the flip chip removal table is rotatably connected to one side of the worktable of the numerically controlled machine tool via a rotating connection mechanism, a built-in cavity is arranged in the middle of the worktable of the numerically controlled machine tool, an in-cavity air cylinder is arranged in the built-in cavity, a cylinder rod of the in-cavity air cylinder is located on a side opposite to the rotating connection mechanism, the in-cavity air cylinder is rotatably connected to the bottom of the built-in cavity via a rotating support, and the air cylinder of the in-cavity air cylinder is arranged on a side opposite to the rotating connection mechanism, The top of the cylinder rod and the bottom surface of the flip-type chip removal table 1 are also rotatably connected via a rotating support. A rotating cylinder rod passing through an opening for the cylinder rod to rotate is provided in the middle of the top surface of the CNC machine tool worktable. The chip cleaning mechanism at the bottom of the table includes a chip blowing pipe arranged around the bottom of the table. The outer wall of the chip blowing pipe is evenly provided with chip blowing air outlets. A chip removal groove is provided on the inner side of the lower enclosure around the top surface of the bottom plate of the CNC machine tool. A slag outlet is provided on the bottom surface in the middle of the chip removal groove. The bottom surface of the chip removal groove is inclined downward toward the slag outlet, and a water inlet pipe is provided at the highest position of the bottom surface of the chip removal groove.
[0007] First, a flip chip removal table is set on the top of the CNC machine tool worktable. After the processing is completed, the flip chip removal table is lifted by the cylinder rod to tilt the flip chip removal table. Under the action of gravity, all the chips on the flip chip removal table can be cleaned into the chassis, and then the chip blowing pipe is started. Since the chip blowing pipe is set at the bottom of the CNC machine tool worktable and the wind blows outward, there is no obstacle for the blown wind, and all the chips in the chassis can be blown into the chip removal groove smoothly. The bottom surface of the drainage ditch is tilted downward toward the slag outlet, and the water flowing out of the water inlet pipe outlet flows along the chip removal groove. The water flow can carry away the debris that enters the chip removal groove and discharge it from the slag outlet. Such chip cleaning can quickly and easily clean the debris in the CNC machine tool case. Since the cylinder in the cavity is rotatably connected to the bottom of the built-in cavity by a rotating support, and the top of the cylinder rod of the cylinder in the cavity and the bottom of the flip-type chip removal table 1 are also rotatably connected by a rotating support, the cylinder rod of the cylinder in the cavity can control the flipping of the flip-type chip removal table. When the cylinder rod of the cylinder in the cavity controls the flipping of the flip-type chip removal table, the cylinder rod of the cylinder in the cavity moves at the opening through which the rotating cylinder rod passes.
[0008] As a further preferred embodiment of the present invention, the rotating connection mechanism is a hinge.
[0009] As a further preferred embodiment of the utility model, the air inlet of the chip blowing pipe is connected to the blower through an air supply pipe, the blower is arranged in the built-in cavity, and one side of the chip blowing pipe is equipped with an air supply pipe and a blower.
[0010] One side of the chip blowing pipe is equipped with an air supply pipe and a blower to keep the wind force on each side of the bottom of the CNC machine tool worktable in the best condition. If the chip blowing pipes on the four sides are only equipped with one air supply pipe and a blower, the wind force of the chip blowing pipe on the side away from the air inlet will be very small and insufficient to complete the chip blowing work.
[0011] As a further preferred embodiment of the present invention, a flat air supply nozzle is provided at the chip blowing air outlet.
[0012] This can increase wind pressure and at the same time increase the air supply coverage area.
[0013] As a further preferred embodiment of the present invention, the slag outlet is connected to a debris collection pool arranged on one side of the CNC machine tool through a slag outlet pipe.
[0014] The debris and water discharged from the slag outlet will flow into the debris collection pool along the slag discharge pipe.
[0015] As a further preferred embodiment of the present invention, a circulating water outlet is provided at the bottom of the debris collection pool, the bottom of the debris collection pool is inclined downward toward the circulating water outlet, and a slag screen is provided at the circulating water outlet.
[0016] After the mixture of debris and water enters the debris collection pool, the water will continue to flow along the bottom of the debris collection pool to the circulating water outlet and then flow out for reuse. The debris interception net can intercept the debris.
[0017] Compared with the prior art, the utility model can achieve at least one of the following beneficial effects:
[0018] 1. It can clean the debris on the workbench of CNC machine tools into the chassis.
[0019] 2. It can conveniently and quickly clean the chassis of CNC machine tools in all directions.
[0020] 3. The side-blowing chip pipe is equipped with an air supply pipe and a blower to keep the wind force on each side of the bottom of the CNC machine tool workbench in the best condition.
[0021] 4. The flat air supply nozzle can increase the wind pressure and at the same time increase the air supply coverage area.
[0022] 5. After the mixture of debris and water enters the debris collection pool, the water will continue to flow along the bottom of the debris collection pool to the circulating water outlet and then flow out for reuse. The debris interception net can intercept the debris. BRIEF DESCRIPTION OF THE DRAWINGS
