Technical Field
[0001] The invention relates to the technical field of numerical control machining, in particular to a numerical control tool with a chip removal function and a use method thereof. Background Art
[0002] When a CNC lathe is turning and cutting, a tool is used. The tool is usually installed in a clamping seat on a moving table. The moving table can drive the tool to move and cut the rotating workpiece on the three-claw chuck. When the tool is cutting the workpiece, strip-shaped chips will be generated. These strip-shaped chips need to be cleaned in time, otherwise they may affect the normal cutting process of the tool. Application number CN202111458565.0 discloses an internal hole processing tool capable of automatic chip removal, comprising a tool bar and a blade connected to the front end of the tool bar; further comprising a conveying structure, a chip breaker plate and a chip guide cover; the tool bar is provided with a chip guide hole and an introduction hole, and the cuttings produced by the blade processing can enter the chip guide hole through the introduction hole; the chip guide cover is connected to the rear end of the tool bar, and the chip guide cover is provided with a radial guide hole; the chip breaker plate is mounted on the wall surface of the introduction hole; the conveying structure comprises a conveying shaft, a chip breaker blade and a conveying blade; When the above patented structure is in use, the waste chips generated by cutting are introduced into the chip guide hole through the introduction hole, the waste chips are first cut off by the chip breaking blade, and then the waste chips are transported by the conveying blade to achieve the purpose of chip removal and cleaning of the processing tool. However, the blade in the above patented structure extends to the outside of the tool rod, so the diameter of the hole cut by the blade is larger than the diameter of the tool rod, which will cause the waste chips to splash into the hole and be wrapped around the tool rod as the workpiece rotates. However, the above patented structure does not have the function of actively cleaning the waste chips wrapped around the tool rod. If the waste chips on the tool rod are not cleaned up in time, the waste chips can easily scratch the hole wall and reduce the processing quality of the boring hole. Summary of the invention

[0013] A method for using a numerical control tool with a chip removal function comprises the following steps: The first step is to place the cutter head required for cutting in the diamond groove, and then fix the cutter head on the cutter seat through the outer screw sleeve and the inner bolt. By fixing the installation area with the moving table on the machine tool, the tool holder can be driven to move and the workpiece can be cut; In the second step, when it is necessary to remove and clean the strip-shaped scraps wound on the tool handle, the forward and reverse motors arranged inside the chassis are started to drive the threaded shaft to rotate, and the threaded shaft can drive the No. 1 T-shaped slide plate to drive the chip removal push plate to move from one side of the cutter head to one side of the chassis through the screw sleeve and the slide plate, and in the process of the chip removal push plate moving, the strip-shaped scraps wound on the tool handle can be pushed from one side of the cutter head to one side of the chassis, so that the strip-shaped scraps wound on the tool handle can be cleaned; In the third step, when the strip-shaped scraps wound on the handle are pushed to the area of the obtuse V-shaped groove by the chip removal push plate, the angle between the cutting knife and the inclined surface of the V-shaped groove is acute. When the annular concave-convex groove drives the cutting knife to move inward through the sliding pin, the cutting knife can cut the strip-shaped scraps. The four groups of cutting knives can cut the strip-shaped scraps wound on the handle into four sections, so that the scraps can fall off the handle after being cut. The fourth step is that after the cutting knife cuts off the strip-like chips, the chip removal push plate continues to drive the four sections of strip-like chips to move on the tool handle. When the chip removal push plate pushes the strip-like chips over the discharge plate, the discharge plate can move upward through the elastic action of the serrated spring. In this process, the discharge plate passes through the middle groove, and then the chip removal push plate moves in the opposite direction and resets. At this time, the discharge plate can hook the strip-like chips on the chip removal push plate, so that the strip-like chips are separated from the chip removal push plate, and the chips cut off from the tool handle can be fallen off through the discharge plate, thereby completing the chip removal and cleaning of the strip-like chips wrapped around the tool handle.
[0014] (III) Beneficial effects The present invention provides a CNC tool with chip removal function and a method of using the tool. The tool has the following beneficial effects: 1. When the side guide column moves from the inclined groove of the side guide groove to the straight groove, the chip removal push plate can move outward to the outside of the chip removal guide groove, so that the subsequent chip removal push plate can move along the straight groove direction of the side guide groove, and when the chip removal push plate moves from one side of the cutter head to one side of the chassis, the push plate inclined surface on the chip removal push plate first contacts with the strip-like chips wrapped around the tool handle, so that the chip removal push plate can push the strip-like chips to move to one side of the V-shaped groove, and at the same time, the push plate inclined surface can exert an oblique downward pressure on the strip-like chips, so that the chip removal push plate is not easy to separate from the chip removal push plate in the process of pushing the strip-like chips to move, so the strip-like chips wrapped around the tool handle can be cleaned.
[0015] 2. When the chip removal push plate pushes the strip-shaped chips into the acute angle, the threaded shaft can drive the driven shaft to rotate through the engagement of the driving gear ring and the driven gear ring, and then the driven shaft can drive the turntable to rotate. When the sliding pin drives the cutting knife to move inward and cut the strip-shaped chips, the four sets of cutting knives can cut the strip-shaped chips wrapped around the handle into four sections, and the strip-shaped chips cut off at the bottom of the handle fall off the handle.
[0016] 3. When the chip removal push plate pushes the cut strip of chips to the discharge plate, in the process of pushing the upper strip of chips to move, it can first contact with the No. 2 inclined surface. When the chip removal push plate pushes the strip of chips over the discharge plate, the discharge inclined surface contacts with the strip of chips, and then the chip removal push plate moves in the opposite direction. The strip of chips on the chip removal push plate can be hooked through the discharge inclined surface. As the discharge inclined surface hooks the strip of chips off the chip removal push plate, the strip of chips on the upper part and both sides of the tool handle can fall off the tool handle, completing the chip removal and cleaning work of the strip of chips wrapped around the tool handle.

[0021] In this embodiment, the chip removal structure 6 includes a cylindrical groove 601, which is arranged at one end of the inner side of the chip removal guide groove 5, and a side guide groove 602 is arranged on the side of the chip removal guide groove 5, a screw sleeve 603 is slidably arranged inside the cylindrical groove 601, a slide plate 604 is fixed on the screw sleeve 603, a No. 1 limiting slide groove 605 is arranged on the slide plate 604, a No. 1 T-shaped slide plate 606 is slidably arranged inside the No. 1 limiting slide groove 605, a chip removal push plate 607 is fixed on the No. 1 T-shaped slide plate 606, a side guide column 608 is fixed on the outer surface of the chip removal push plate 607, an intermediate groove 6071 is arranged in the middle of the chip removal push plate 607, a push plate inclined surface 6072 is arranged on one side of the chip removal push plate 607, and a No. 1 inclined surface 6073 is arranged on the other side of the chip removal push plate 607; For details, please refer to the attached manual. Figure 5As shown, the threaded shaft 302 can drive the screw sleeve 603 to move inside the cylindrical groove 601. When the screw sleeve 603 moves, the chip removal push plate 607 can be driven to move through the slide plate 604 and the No. 1 T-shaped slide plate 606. At this time, the chip removal push plate 607 can move to the outside of the chip removal guide groove 5. When the chip removal push plate 607 continues to move, the push plate inclined surface 6072 first contacts with the strip-like chips wrapped around the tool handle 1, and the chip removal push plate 607 can push the strip-like chips wrapped around the tool handle 1 to move. When the chip removal push plate 607 moves in the opposite direction and the tool handle 1 is already wrapped with strip-like chips, the No. 1 inclined surface 6073 makes it easier for the chip removal push plate 607 to pass through the strip-like chips wrapped around the tool handle 1, so that the chip removal push plate 607 can continue to be received in the chip removal guide groove 5, which is convenient for the subsequent cleaning of the strip-like chips wrapped around the tool handle 1.
[0022] In this embodiment, the screw sleeve 603 is threadedly connected to the threaded shaft 302, the slide plate 604 is slidably connected to the chip removal guide groove 5, the side guide column 608 is slidably connected to the side guide groove 602, and the side guide groove 602 is composed of an inclined groove and a straight groove; Specifically, by slidingly connecting the slide plate 604 with the chip removal guide groove 5, the screw sleeve 603 can be prevented from rotating, so that the screw sleeve 603 can move inside the cylindrical groove 601. When the side guide column 608 moves from the inclined groove of the side guide groove 602 to the straight groove, the No. 1 T-shaped slide plate 606 slides with the slide plate 604, and through the guidance of the side guide groove 602 to the side guide column 608, the chip removal push plate 607 can be moved outward to the outside of the chip removal guide groove 5, so that the subsequent chip removal push plate 607 can move along the straight groove direction of the side guide groove 602.
[0023] In this embodiment, the cutting structure 7 includes a V-shaped groove 701, and the obtuse V-shaped groove 701 is provided on the surface of the tool handle 1, a receiving groove 702 is provided on the side of the V-shaped groove 701 away from the chip removal push plate 607, a side through groove 703 is provided on the side of the receiving groove 702, a cutting knife 704 slides inside the receiving groove 702, a sliding pin 705 is fixed on the cutting knife 704, a rotating disk 706 is fixed on the driven shaft 303, and an annular concave-convex groove 707 is provided on the end surface of the rotating disk 706; For details, please refer to the attached manual. Figure 8As shown, the angle between the cutting knife 704 in the initial position and the inclined surface close to the receiving groove 702 is an acute angle, that is, the blade of the cutting knife 704 is moved out of the receiving groove 702. When the chip pusher 607 pushes the strip-shaped scraps into the V-shaped groove 701, the chip pusher 607 at the corner line can tighten the strip-shaped scraps. When the strip-shaped scraps enter the V-shaped groove 701, the strip-shaped scraps can be close to the surface of the V-shaped groove 701. By setting the V-shaped groove 701, The surface of the V-groove 701 and the cutting knife 704 can have a certain angle so that the strip-like scraps can enter the angle. The turntable 706 drives the cutting knife 704 to move inward through the sliding pin 705, and cuts off the strip-like scraps wound on the handle 1. The four groups of cutting knives 704 can cut the strip-like scraps into four sections. The strip-like scraps at the bottom of the handle 1 fall off the handle 1, and the strip-like scraps at the top and both sides remain on the handle 1, so that the strip-like scraps on the handle 1 can be cleaned up later.
[0024] In this embodiment, the sliding pin 705 passes through the side through groove 703 and extends into the annular concave-convex groove 707, and the sliding pin 705 is slidably connected with the side through groove 703; Specifically, when the rotating disk 706 drives the sliding pin 705 to move through the annular concave-convex groove 707, the sliding pin 705 moves in the vertical direction inside the side through groove 703, so that the sliding pin 705 can drive the cutting knife 704 to move in the vertical direction.
[0025] In this embodiment, the inner wall of the annular concave-convex groove 707 is concave-convex, and the concave parts and the convex parts are arranged alternately; Specifically, when the sliding pin 705 moves from the convex part to the concave part of the annular concave-convex groove 707, it can drive the sliding pin 705 to move inward. At this time, the sliding pin 705 can drive the cutting knife 704 to move inward. Similarly, when the sliding pin 705 moves from the concave part to the convex part of the annular concave-convex groove 707, it can drive the sliding pin 705 to move outward. At this time, the sliding pin 705 can drive the cutting knife 704 to move outward, so that the blade part of the cutting knife 704 moves out of the storage groove 702. Therefore, when the cutting knife 704 moves inward, it can cut the strip-shaped scraps. When the cutting knife 704 moves outward, an angle is left between the cutting knife 704 and the surface of the V-shaped groove 701, so that the strip-shaped scraps can be cut off after the cutting knife 704 enters the angle.
[0026] In this embodiment, the unloading structure 8 includes a No. 2 limiting slide 801, which is provided on the inner wall of the chip removal guide groove 5 and is close to the chassis 3. A limiting opening 804 is provided at the end of the No. 2 limiting slide 801. A No. 2 T-shaped slide 802 is slidably arranged inside the No. 2 limiting slide 801.

A discharge inclined surface 8051 is provided on one side of the discharge plate 805, and a No. 2 inclined surface 8052 is provided on the other side of the discharge plate 805. For details, please refer to the attached manual. Fig.10 As shown, in the initial position, the discharge plate 805 moves out to the outside of the chip removal guide groove 5, so that the discharge slope 8051 and the second slope 8052 are exposed from the chip removal guide groove 5. When the chip removal push plate 607 pushes the strip-like chips over the discharge plate 805, and then the chip removal push plate 607 moves in the opposite direction, the strip-like chips on the chip removal push plate 607 can be hooked by the discharge slope 8051, and the strip-like chips can be separated from the chip removal push plate 607.
[0027] In this embodiment, one end of the sawtooth spring 803 is fixedly connected to the inner wall of the second limiting slide groove 801, and the other end of the sawtooth spring 803 is fixedly connected to the second T-shaped slide plate 802; Specifically, the extension or contraction of the sawtooth spring 803 can drive the second T-shaped slide plate 802 to move and reset, and the second T-shaped slide plate 802 can drive the unloading plate 805 to move and reset.
[0028] In this embodiment, the discharge plate 805 passes through the middle groove 6071 and is adapted to the middle groove 6071; Specifically, during the movement of the chip removal push plate 607 , the cutting blade 704 and the discharge plate 805 can pass through the middle groove 6071 without interfering with the side guide column 608 , so that the chip removal push plate 607 can move freely laterally.
[0029] A method for using a numerical control tool with a chip removal function comprises the following steps: In the first step, the cutter head 405 required for cutting is placed in the diamond groove 401, and then the cutter head 405 is fixed on the cutter seat 4 through the outer screw sleeve 403 and the inner bolt 404, and the mounting area 2 is fixedly mounted on the moving table on the machine tool to drive the tool handle 1 to move and cut the workpiece; In the second step, when it is necessary to remove and clean the strip-shaped scraps wound on the tool handle 1, the forward and reverse motors arranged inside the chassis 3 are started to drive the threaded shaft 302 to rotate, and the threaded shaft 302 can drive the No. 1 T-shaped slide 606 to drive the chip removal push plate 607 to move from one side of the cutter head 405 to one side of the chassis 3 through the screw sleeve 603 and the slide plate 604, and in the process of the chip removal push plate 607 moving, the strip-shaped scraps wound on the tool handle 1 can be pushed from one side of the cutter head 405 to one side of the chassis 3, so that the strip-shaped scraps wound on the tool handle 1 can be cleaned; In the third step, when the strip-shaped scraps wound on the handle 1 are pushed to the area of the obtuse-angled V-shaped groove 701 by the chip removal push plate 607, the angle between the cutting knife 704 and the inclined surface of the V-shaped groove 701 is acute. When the annular concave-convex groove 707 drives the cutting knife 704 to move inward through the sliding pin 705, the cutting knife 704 can cut the strip-shaped scraps. The four groups of cutting knives 704 can cut the strip-shaped scraps wound on the handle 1 into four sections, so that the scraps can be dropped from the handle 1 after being cut. In the fourth step, after the cutting knife 704 cuts off the strip-like scraps, the chip removal push plate 607 continues to drive the four sections of strip-like scraps to move on the tool handle 1. After the chip removal push plate 607 pushes the strip-like scraps over the discharge plate 805, the discharge plate 805 can be moved upward by the elastic action of the serrated spring 803. In this process, the discharge plate 805 passes through the middle groove 6071, and then the chip removal push plate 607 is moved in the opposite direction and reset. At this time, the discharge plate 805 can hook the strip-like scraps on the chip removal push plate 607, so that the strip-like scraps are separated from the chip removal push plate 607, and the cut-off scraps on the tool handle 1 can be dropped off by the discharge plate 805, thereby completing the chip removal and cleaning of the strip-like scraps wrapped around the tool handle 1.
[0030] The working principle and use process of the present invention are as follows: the cutter head 405 required for cutting processing is fixed on the cutter seat 4 by the outer screw sleeve 403 and the inner bolt 404, and the tool holder 1 can be driven to move and the workpiece can be cut by fixing the installation area 2 to the moving table on the machine tool. When it is necessary to remove and clean the strip-shaped scraps wound on the tool holder 1, the forward and reverse motors arranged inside the chassis 3 are started and the threaded shaft 302 is driven to rotate, and the threaded shaft 302 can drive the screw sleeve 603 to move inside the cylindrical groove 601, and the slide plate 604 slides inside the chip removal guide groove 5, and the slide plate 604 drives the chip removal push plate 607 to move through the No. 1 T-type slide plate 606, and the chip removal push plate 607 drives the side guide column 608 to slide inside the side guide groove 602, as shown in the attached manual. Figure 5As shown, when the side guide column 608 moves from the inclined groove of the side guide groove 602 to the straight groove, the No. 1 T-shaped slide plate 606 slides with the slide plate 604, and the side guide groove 602 guides the side guide column 608, so that the chip removal push plate 607 can be moved outward to the outside of the chip removal guide groove 5, so that the subsequent chip removal push plate 607 can move along the straight groove direction of the side guide groove 602, and in the process of the chip removal push plate 607 moving from one side of the tool head 405 to one side of the chassis 3, the push plate inclined surface 6072 on the chip removal push plate 607 first contacts with the strip-like chips wrapped around the tool handle 1, so that the chip removal push plate 607 can push the strip-like chips to move to the side of the V-shaped groove 701, and at the same time, the push plate inclined surface 6072 can have a certain effect on the strip-like chips. The downward pressure makes it difficult for the chip removal push plate 607 to separate from the chip removal push plate 607 during the process of pushing the strip-like scraps to move. Therefore, the strip-like scraps wrapped around the tool handle 1 can be cleaned and removed. When the chip removal push plate 607 pushes the strip-like scraps to the inside of the obtuse-angled V-groove 701, the cutting knife 704 moves to the outside of the receiving groove 702. At the same time, the angle between the blade part of the cutting knife 704 and the inclined surface on one side of the receiving groove 702 is acute. When the chip removal push plate 607 pushes the strip-like scraps to the acute angle, the threaded shaft 302 can drive the driven shaft 303 to rotate through the engagement of the driving gear ring 304 and the driven gear ring 305, and then the driven shaft 303 can drive the turntable 706 to rotate, as shown in the attached manual. Figure 8 As shown, during the rotation of the turntable 706, the sliding pin 705 moves inside the annular concave-convex groove 707. When the sliding pin 705 moves from the convex part of the annular concave-convex groove 707 to the concave part, it can drive the sliding pin 705 to move inward. At this time, the sliding pin 705 can drive the cutting knife 704 to move inward and cut the strip-like scraps. The four groups of cutting knives 704 can cut the strip-like scraps wound on the knife handle 1 into four sections. The strip-like scraps at the bottom of the knife handle 1 fall off from the knife handle 1 after being cut off, and the scraps at the top and both sides remain on the knife handle 1. After the strip-like scraps are cut off, the chip removal push plate 607 continues to push the cut strip-like scraps to move on the knife handle 1. When the chip removal push plate 607 pushes the cut strip-like scraps to the discharge plate 805, as shown in the attached manual Fig.10As shown, in the process of the chip removal push plate 607 pushing the upper strip-shaped scraps to move, it can first contact with the No. 2 inclined surface 8052, and at the same time, the strip-shaped scraps can push the discharge plate 805 to move inward through the No. 2 inclined surface 8052 and be stored in the chip removal guide groove 5, and the discharge plate 805 drives the No. 2 T-type slide plate 802 to move inward and drives the serrated spring 803 to deform. When the chip removal push plate 607 pushes the strip-shaped scraps to cross the discharge plate 805, the serrated spring 803 resets and drives the discharge plate 805 to move out of the chip removal guide groove 5 through the No. 2 T-type slide plate 802. At this time, the discharge inclined surface 8051 contacts with the strip-shaped scraps, and then the threaded shaft 302 is reversed to make the chip removal push plate 607 move in the opposite direction. At this time, the strip of chips on the chip removal push plate 607 can be hooked by the unloading slope 8051, and the elastic force of the serrated spring 803 enables the unloading slope 8051 to have an oblique upward thrust on the strip of chips, so that the unloading plate 805 can drive the strip of chips to move obliquely upward and disengage from the chip removal push plate 607, and the chip removal push plate 607 moves to the initial position again and resets to wait for the next chip removal and cleaning of the strip of chips on the tool handle 1. As the unloading plate 805 continues to move outward, the unloading slope 8051 can move the strip of chips on the upper part and both sides of the tool handle 1 outward and fall off the tool handle 1, completing the chip removal and cleaning work of the strip of chips wrapped around the tool handle 1.
