Description

Technical Field

[0001] This invention relates to the field of metal cutting technology, specifically a metal cutting drill bit and its equipment. Background Technology

[0002] Metal cutting drill bits are rotary cutting tools used to machine holes in metal materials, achieving cutting through rotational and axial feed motions.

[0003] The prior art discloses Chinese Patent No. CN 104191001 A: a drill bit, which discloses that the cutting part is provided with two helical cutting edges. The helical cutting edges include a main cutting edge and a helical side edge at the front end of the cutting part. The main cutting edges meet at the front end of the cutting part and form a protrusion. The main cutting edges continue to extend helically on the protrusion and stop at the front end axis to form a pointed tip. The helical side edge is provided with multiple notches evenly along the helical direction. The helical side edge corresponding to the notch in front of the notch gradually shrinks towards the bottom of the notch and smoothly connects with the bottom of the notch. The helical side edge corresponding to the notch behind the notch connects with the rear end of the notch with an inclined surface.

[0004] However, the aforementioned existing technology still has certain drawbacks. During use, the spiral cutting edge is subjected to a large cutting impact during drilling, which can easily cause chipping.

In addition, by setting each independent tooth as an arc structure with an isosceles trapezoidal cross section, the cutting impact during the drilling process can be effectively reduced and the tool life can be improved. 2. This invention utilizes a plate feeding mechanism to intermittently drive a metal plate clamped by a plate holding mechanism forward. After each plate advance is completed, a plate fixing mechanism is used to fix and limit the target metal plate.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] The metal cutting drill bit of this invention belongs to the category of cutting tools and is used for drilling target workpieces. It is generally used as an accessory tool for metal cutting machine tools.

[0023] The drilling equipment of this invention belongs to a part of the intelligent manufacturing equipment industry. It is a type of drilling equipment mainly used for continuous equidistant drilling of metal plates.

[0024] Example 1: Refer to the appendix of the instruction manual. Figures 1-2 This embodiment is the first embodiment of the present invention, which provides a metal cutting drill bit, the metal cutting drill bit including a drill bit body; The drill bit body includes a drill rod 2, a mounting base 1 fixedly installed at one end of the drill rod 2, and a carbide cutting tool 4 brazed to the other end of the drill rod 2; A spiral groove 3 is provided on the outer side of the end of the drill rod 2 away from the mounting base 1. There are three spiral grooves 3, which are arranged in a centrally symmetrical manner around the central axis of the drill rod 2.

[0025] Furthermore, the carbide insert 4 is configured as an integral three-blade structure with equidistant distribution. The cone angle formed by the three cutting edges of the carbide insert 4 is 120°. Multiple equally spaced cutting edges 5 are fixed on each cutting edge, and the cutting edges 5 on adjacent cutting edges are staggered. When the multiple staggered cutting edges 5 on the three cutting edges are connected sequentially, a set of spiral cutting edges 5 can be formed, which can effectively reduce the vibration generated during drilling and make the drilling process more stable. At the same time, the staggered design of the cutting edges on the three cutting edges can realize point-to-surface layered cutting, improving drilling efficiency. In addition, each independent cutting edge 5 is set as an arc structure with an isosceles trapezoidal cross section, which can effectively reduce the cutting impact during drilling and improve the tool life.

[0026] Example 2: Refer to the appendix of the instruction manual. Figures 3-4 This embodiment is the second embodiment of the present invention, providing a drilling device for a metal cutting drill bit, the drilling device comprising: The base 6, drill head 7 and plate conveying part 8 are all installed on the top of the base 6. The drill head 7 includes a drill feed mechanism 71 and a drill mounting mechanism 72 installed at the feed end of the drill feed mechanism 71. The drill body can be detachably installed on the drill mounting mechanism 72. The sheet metal conveying unit 8 includes a frame 81, a sheet metal clamping mechanism 82 passing through the frame 81, a sheet metal feeding mechanism 83 installed at one end of the frame 81, a sheet metal fixing mechanism 84 installed on one side of the frame 81, and a chip collection assembly 85 installed at the bottom center of the frame 81. The target metal sheet to be drilled is placed on the sheet metal clamping mechanism 82 and fed stepwise by the sheet metal feeding mechanism 83. The drill head 7 is located in the middle of the frame 81. A through hole is opened on one side of the drill head 7 on the frame 81, which is directly opposite to the drill bit (i.e., the aforementioned metal cutting drill bit, the same below).

[0027] It should be noted that the present invention uses a plate feeding mechanism 83 to intermittently drive the metal plate clamped by the plate holding mechanism 82 forward, and after each plate advance is completed, the plate fixing mechanism 84 is used to fix and limit the target metal plate. Then, under the action of the drill bit feeding mechanism 71, the drill bit installed on the drill bit mounting mechanism 72 is driven to continuously drill holes at equal intervals in the metal plate. At the same time, the chip collection component 85 is used to collect and process the waste chips generated during the cutting and drilling process.

[0028] Furthermore, such as Figure 4 and Figure 10As shown, the drill bit feed mechanism 71 includes a column 712 fixed to the top of the base 6 and a dovetail groove opened on the top of the base 6. A cylinder 713 is fixedly installed on the top of the column 712. An L-shaped seat 711 is fixedly connected to the telescopic end of the cylinder 713. A dovetail block is fixedly provided at the bottom of the L-shaped seat 711 and slidably connected inside the dovetail groove. The bottom surface of the L-shaped seat 711 moves in contact with the upper surface of the base 6. At the same time, an inclined platform is added to the middle of the inner side of the L-shaped seat 711 to improve the impact resistance of the L-shaped seat 711 during the cutting and drilling process.

[0029] It should be noted that during the feeding process of the drill bit mounted on the drill bit mounting mechanism 72, the L-shaped seat 711 is moved along the upper surface of the base 6 by the cylinder 713, and the dovetail groove and dovetail block are used in combination to improve the stability of the drill bit feed during the cutting and drilling process.

[0030] Furthermore, such as Figures 4-5 and Figures 9-10 As shown, the plate clamping mechanism 82 includes a square ring frame 821 fixedly connected to both ends of the frame 81 and four L-shaped buckle plates 823 located between the two square ring frames 821. Two cross grooves 822 are opened through each of the four sides of the square ring frame 821. A bar post 824 is movably inserted inside each cross groove 822. A guide groove is opened in the middle of each bar post 824. A square bar slidably connected to the corresponding cross groove 822 is movably inserted inside each guide groove. One end of the bar post 824 on both sides of each corner of the square ring frame 821 is fixedly connected to the corresponding L-shaped buckle plate 823. The square bar and the corresponding bar post 824 are always vertically arranged, thereby ensuring that the two L-shaped buckle plates 823 that are horizontally opposite or vertically opposite each other undergo stable translational movement under power drive. Telescopic frames are fixedly installed at the center of the four sides of the two square ring frames 821. A dual-axis motor 825 is fixedly installed at one end of each telescopic frame. The two output shafts of the dual-axis motor 825 are fixedly connected to studs 826. The threads on the outside of the studs at the two output shafts of the same dual-axis motor 825 are oppositely arranged. Two bars 824 on the same side of the square ring frame 821 are respectively threaded onto the outside of the corresponding studs 826. Multiple rotating cylinders 827 are rotatably installed on the inside of each L-shaped buckle plate 823. Multiple balls 828 are also rolled and embedded on the inside of each L-shaped buckle plate 823. The design of the rotating cylinders 827 and the balls 828 can convert the static friction between the metal sheet to be processed and the L-shaped buckle plate 823, which is fastened and fixed by the four L-shaped buckle plates 823, into rolling friction, thereby reducing the energy loss when the plate feeding mechanism 83 drives the target plate forward.

[0031] Furthermore, the telescopic frame includes a sleeve fixedly connected to the outside of the square ring frame 821, a sleeve rod seat fixedly connected to the corresponding dual-axis motor 825, and a connecting spring that fixes the sleeve and the sleeve rod seat. The connecting spring and the end of the sleeve rod seat near the sleeve are both located inside the sleeve. This telescopic frame ensures that during the process of adjusting the relative position of the four L-shaped buckles 823 to clamp the target metal plate, the four L-shaped buckles 823 undergo stable feeding motion under the drive of the corresponding dual-axis motor 825. In addition, an infrared rangefinder 829 is installed on the inclined surface area of ​​the inclined platform in the middle of the inner side of the L-shaped seat 711 to detect the relative position change between the L-shaped seat 711 and the debris collection assembly 85, thereby controlling the plate fixing mechanism 84 to limit and fix the metal plate that has completed a single-pass advance.

[0032] Furthermore, such as Figures 7-9 As shown, the frame 81 is also equipped with a splash-proof component 86. The splash-proof component 86 includes a triangular prism 861 located between two vertically symmetrical L-shaped buckles 823. The triangular prism 861 is fixedly connected to the corresponding L-shaped buckle 823, and metal spring pieces 862 are fixedly connected between the two ends of the vertically symmetrical triangular prisms 861. Each triangular prism 861 is set as a right-angled triangle structure, and the right-angled side that does not contact the L-shaped buckle 823 is in contact with the surface of the clamped and positioned metal plate for movement.

[0033] It should be noted that during the clamping and positioning of the target metal plate, the two studs 826 are driven to rotate by the dual-axis motors 825 located at the top and bottom of the square ring frame 821. The rotating studs 826 drive the two horizontally corresponding bars 824 to move towards and away from each other, so that the target metal plate is supported between the two L-shaped buckles 823 at the bottom. Then, the corresponding studs 826 are driven to rotate so that the two horizontally opposite L-shaped buckles 823 move towards each other, thus clamping and limiting the target metal plate on both sides perpendicular to the drill bit direction. Next, the two studs 826 are driven to rotate by the dual-axis motors 825 located on both sides of the square ring frame 821. The rotating studs 826 drive the two vertically opposite L-shaped buckles 823 to move towards each other, thus clamping and limiting the target metal plate on both sides parallel to the drill bit direction. This achieves stable clamping and positioning of the target metal plate using four L-shaped buckles 823. Specifically, during the adjustment of the relative positions of the four L-shaped buckles 823, the two sets of triangular prisms 861 arranged vertically and collinearly will also move towards each other, causing the bending angle of the metal spring 862 connecting the two triangular prisms 861 to change. The metal spring 862 and the corresponding triangular prism 861 cooperate to form a closed cavity to prevent debris from splashing during the cutting and drilling process. The inclined surface of the triangular prism 861 is used to guide the debris to fall to the debris collection component 85 to complete the collection of debris. After the target metal sheet is clamped and positioned, the sheet feed mechanism 83 drives the sheet to advance step by step. After each single advance, cylinder 713 pushes the L-shaped seat 711 towards the frame 81, so that the rotating drill bit can cut and drill the target metal sheet as the L-shaped seat 711 is fed. During the advance of the L-shaped seat 711, when the infrared rangefinder 829 detects that the rotating drill bit is about to enter the frame 81, it transmits a signal to the control terminal, which controls the sheet fixing mechanism 84 to fix and limit the sheet after it has been pushed, so as to prevent the sheet from moving during the subsequent cutting and drilling process and causing the drilling to deviate.

[0034] Furthermore, such as Figure 4 and Figure 6 As shown, the sheet metal feeding mechanism 83 includes column blocks 831 fixed in the middle of both sides of the frame 81. Guide rods 832 are fixedly connected to the top and bottom of each column block 831. Two guide rods 832, arranged vertically and collinearly, have ear plates 833 movably fitted on their outer sides to fit against the outer side of the frame 81. Connecting posts 834 are provided between the two ear plates 833 on the same side of the frame 81 and their corresponding posts 824. One end of the connecting post 834 near the corresponding ear plate 833 is fixedly connected to the ear plate 833, while the other end of the connecting post 834 is slidably installed with the corresponding post 824 in the horizontal direction. Without detaching from the corresponding column 824, the distance between the two feed units, one above the other, can be adjusted according to the height of the target metal sheet through the cooperation of the guide rod 832 and the connecting column 834. Two horizontally opposite ear plates 833 are rotatably mounted with shafts. The shafts are driven by a servo motor mounted on the outside of one of the ear plates 833. A drive disk 835 is fixedly sleeved on the middle of the outer side of each of the two shafts. The drive disk 835 has a recessed area on its circumferential side. At the same time, the non-recessed area of ​​the drive disk 835 is covered with an anti-slip soft pad to better drive the target metal sheet forward.

[0035] It should be noted that during the process of using the plate feeding mechanism 83 to drive the target metal plate forward, after the plate clamping mechanism 82 completes the clamping and positioning of the target metal plate, the center of the recessed area on the drive disk 835 is aligned with the target metal plate (this state is considered the initial state). At this time, the drive disk 835 and the target metal plate are set apart. Subsequently, the servo motor drives the corresponding drive disk 835 to rotate. When the drive disk 835 rotates to the point where its non-recessed area contacts the target metal plate, the two are in an interference fit. At this time, as the drive disk 835 rotates, it will drive the target metal plate forward. During this process, the drive disk 835 will complete a cutting and drilling operation with the feed drill bit for each rotation before proceeding to the next round of plate feeding.

[0036] Furthermore, such as Figures 6-7 As shown, the plate fixing mechanism 84 includes a second cylinder 841 fixed on the outside of the frame 81. A straight plate 842 is fixedly connected to the telescopic end of the second cylinder 841. A round rod 843 that can move through the corresponding side of the frame 81 is fixedly provided at the four corners of the straight plate 842. A vacuum suction cup 844 is fixedly installed at one end of each round rod 843 located inside the frame 81.

[0037] It should be noted that after each target metal sheet is advanced, the control end will control cylinder 841 to pull the straight plate 842 closer to the frame 81 before cutting and drilling, thereby pushing the round rod 843 to continue to insert into the frame 81, and simultaneously driving the vacuum suction cup 844 to move closer to the target metal sheet. When the vacuum suction cup 844 moves to make close contact with the corresponding side surface of the target metal sheet, the vacuum suction cup 844 is activated to complete the suction and fixation of the target metal sheet in the current state, so as to prevent the sheet from shifting during the subsequent cutting and drilling process, which would cause drilling deviation and affect the quality of the finished product.

[0038] Furthermore, such as Figure 4 and Figure 6 As shown, the debris collection assembly 85 includes a through groove in the middle of the bottom of the frame 81 and a collection chamber fixedly disposed at the bottom of the frame 81 and communicating with the through groove. A mesh plate is fixedly disposed inside the collection chamber, which can be used to divide the inner cavity of the collection chamber into a debris area and a coolant recovery area. The debris falling with the coolant is filtered out by the mesh plate. A door is hinged to the collection chamber above the mesh plate to facilitate cleaning of the debris filtered out inside the collection chamber. A liquid pipe is connected to the collection chamber below the mesh plate to draw out the filtered coolant for reuse.

[0039] Example 3: Refer to the appendix of the instruction manual. Figure 1 , Figure 4 and Figures 10-14This embodiment is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the drill bit mounting mechanism 72 includes a shaft 721 rotatably mounted on an L-shaped seat 711 via a bearing. The shaft 721 is driven to rotate by a drive motor mounted on the outside of the L-shaped seat 711. One end of the shaft 721 is fixedly connected to a disc 722. The bottom of the disc 722 is fixedly connected to an outer cylinder 723. An inner cylinder 724 is movably sleeved inside the outer cylinder 723. Furthermore, a square collar 7217 is fixedly installed on the inner side of the outer cylinder 723, and an annular groove 7219 is formed on the inner side of the inner cylinder 724. A retaining groove 7220 is formed on the top of the inner side of the annular groove 7219, and a vertical groove 7221 communicating with the annular groove 7219 is also formed on the inner side of the inner cylinder 724. The vertical groove 7221 and the retaining groove 7220 are staggered. An elastic element 7218 is fixedly installed on the bottom of the inner side of the inner cylinder 724. The elastic element 7218 consists of an annular plate and an elastic telescopic rod that fixes the inner cylinder 723 to the annular plate. The specific structure of the elastic telescopic rod is similar to that of a telescopic rod. The structure of the retractable frame will not be described in detail here. The mounting base 1 includes a circular plate fixedly connected to the drill rod 2, a clamping plate fixedly disposed on the circumferential side of the circular plate, and a square column fixed on the side of the circular plate away from the drill rod 2. The square column is adapted to the square collar 7217. Multiple clamping slots 7220 and vertical grooves 7221 are provided (this application uses three as an example for explanation). A stop bar is fixedly provided inside the annular groove 7219 at one end of each clamping slot 7220, which can better determine the precise position of the clamping plate rotating within the annular groove 7219 to the clamping slot 7220.

[0040] Furthermore, a docking assembly is provided between the outer cylinder 723 and the inner cylinder 724. The docking assembly includes three through slots 725 on the upper circumferential side of the outer cylinder 723 and three through slots 726 on the lower circumferential side of the outer cylinder 723 and the upper circumferential side of the inner cylinder 724. The through slots 726 on the outer cylinder 723 and the inner cylinder 724 are arranged in a one-to-one correspondence. A lifting frame 727 is movably fitted on the outside of the square collar 7217. The lifting frame 727 consists of a lifting plate and three extension plates fixed on the outside of the lifting plate. The lifting plate is movably fitted on the outside of the square collar 7217. One end of the extension plate passes through the corresponding through slot 725. An adjusting ring 728 is also threaded onto the outside of the outer cylinder 723. Multiple L-shaped rods are fixedly arranged at equal intervals on the circumferential side of the adjusting ring 728 to facilitate better rotation of the adjusting ring 728.

[0041] Furthermore, the docking assembly also includes a track frame 7210 fixed on the outside of the outer cylinder 723 corresponding to the through slot 725, and an adjusting cylinder 729 sleeved on the outside of the outer cylinder 723. An extension plate penetrating the corresponding through slot 725 overlaps the upper surface of the adjusting cylinder 729. A slide block 7215 is slidably mounted on the track frame 7210. An L-shaped frame 7211 is fixedly connected to the top of the slide block 7215. A locking post 7214 is fixedly provided on the inner side of the L-shaped frame 7211, which movably penetrates the corresponding through slot 726. The length of the locking post 7214 is greater than the sum of the depths of the two connected through slots 726. Straight bars 7212 are fixedly arranged correspondingly on the inner side of both the L-shaped frame 7211 and the adjusting cylinder 729. A swing arm 7213 is hinged between the two corresponding straight bars 7212. Two sets of swing arms 7213 are provided; their specific positions are shown in [reference needed]. Figure 12 One end of the straight bar 7212 inside the adjusting cylinder 729 is fixedly provided with a straight rod 7216 that moves through the corresponding track frame 7210. A straight spring is sleeved on the outside of the straight rod 7216 to fix the corresponding straight bar 7212 and the track frame 7210. When the adjusting ring 728 is at the high point outside the outer cylinder 723, the end of the locking pin 7214 is completely hidden inside the through groove 725 on the outer cylinder 723, and the straight rod 7216 is still in the state of moving through the corresponding track frame 7210. At the same time, the straight spring is still in the compressed state.

[0042] It should be noted that during the process of installing the drill bit onto the drill bit mounting mechanism 72, the drill rod 2 of the drill bit is first inserted from the upper end of the inner cylinder 724, allowing the insertion end of the drill rod 2 to pass through the core hole at the center of the bottom end of the inner cylinder 724. During the insertion of the drill bit, the position of the mounting base needs to be adjusted so that the three retaining plates on the circumferential side of the circular plate correspond one-to-one with the three vertical grooves 7221 on the inner side of the inner cylinder 724, and move downwards along the vertical grooves 7221 into the annular groove 7219. During this process, as the circular plate gradually moves downwards... Before the chuck plate enters the annular groove 7219, it is already in contact with the annular plate. After the chuck plate enters the annular groove 7219, the downward circular plate will push the annular plate downward to squeeze the elastic telescopic rod. After the chuck plate is fully inside the annular groove 7219, the drill rod 2 will be rotated, so that the mounting seat 1 will be rotated synchronously to the position where the chuck plate and the chuck groove 7220 are directly opposite each other. Then the external force applied to the drill bit will be removed, and the chuck plate will be pushed into the corresponding chuck groove 7220 by the rising and reset annular plate under the restoring force of the elastic telescopic rod. After the drill bit and inner cylinder 724 are assembled, the inner cylinder 724 is inserted into the outer cylinder 723. During the insertion process, the square post on the mounting base 1 is inserted into the square collar 7217 inside the outer cylinder 723. This ensures that after the inner cylinder 724 is inserted into the outer cylinder 723 (i.e., the circular plate is pushed by the square collar 7217), the two through slots 726 are connected one by one. Then, the adjusting ring 728 is rotated to push the lifting frame 727 downward, and the downward lifting frame 727 pushes the adjusting cylinder 729 downward. During the downward movement of the adjusting cylinder 729, the straight bar 7212 on the inner side of the adjusting cylinder 7229 will compress the straight spring downward along the corresponding straight rod 7216. At the same time, the angle of the swing arm 7213 between the two corresponding straight bars 7212 will change, thereby pushing the L-shaped frame 7211 closer to the inner cylinder 724 along the direction of the track frame 7210, allowing the locking pin 7214 to be inserted into the two corresponding through slots 726. In this way, the installation of the drill bit can be completed. The entire installation process can be carried out without operating tools, and the disassembly and assembly are convenient and quick.
