Description

Technical Field

[0001] This invention relates to the field of drill bit processing technology, specifically to an intelligent precision machining device for controlling the geometric parameters of drill bits. Background Technology

[0002] A drill bit is a common cutting tool used to machine holes in materials such as metal, wood, plastic, and stone. During use, the cutting performance, machining accuracy, and service life of a drill bit are highly dependent on the rationality of geometric parameters such as the point angle, clearance angle, and helix angle. Different materials being machined, hole diameters, and working conditions place significant differences in the requirements for the geometric parameters of the drill bit.

[0003] Currently, intelligent precision machining devices for controlling drill bit geometry parameters often generate a large amount of metal chips and dust during drilling and grinding processes. These chips tend to accumulate on the underside of the drive box and in the machining area. The chips generated during machining rely on manual periodic cleaning or centralized cleaning after machining. The cleaning methods are scattered and inefficient, often requiring machine shutdown, which can easily cause interruptions in the machining process and increase the intensity of manual labor. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an intelligent precision machining device for controlling the geometric parameters of drill bits.

[0016] A method for controlling the geometric parameters of an intelligent precision machining device for controlling the geometric parameters of drill bits, the method comprising the following steps:

[0017] S1. The drill bit to be processed is clamped on the chuck connected to the power shaft inside the drive box. The chuck is used to achieve axial positioning and clamping of the drill bit. Then, the electric slide is started so that the limiting component can assist in limiting the position of the drill bit.

[0018] S2. Start the motor inside the worktable to drive the lead screw to rotate, so that the moving frame moves linearly along the direction of the fixed frame. Through the displacement of the moving frame, the position of the grinder in the axial and radial directions can be adjusted, providing a motion basis for the control of the drill bit's geometric parameters.

[0019] S3. During the movement of the moving frame, the rotating component drives the grinder to change its position and posture relative to the drill bit, so that the grinding part of the grinder and the cutting edge of the drill bit form a preset relative angle and contact position, thereby accurately grinding the geometric parameters of the drill bit. The control box controls the motor, lead screw and electric slide to achieve smooth feed and controllable adjustment during the geometric parameter adjustment process.

[0020] This invention provides an intelligent precision machining device for controlling the geometric parameters of drill bits. It has the following beneficial effects:

[0021] 1. This invention moves the movable frame to the right to a suitable position, so that the fixed plate contacts the cleaning frame. The magnetic blocks are used to magnetically attract the iron block, causing it to move downward and limiting the cleaning frame. The movable frame moves to the left, pulling the cleaning frame to the left to clean the debris on the lower side of the drive box and the processing area. No additional manual cleaning steps are required, realizing integrated processing and cleaning, avoiding processing interruptions caused by manual cleaning, and facilitating the optimization of the processing environment.

[0022] 2. This invention places the drill bit in the center of the chuck in the drive box and controls the grinder to rotate to a suitable angle for movement via the control box. By changing different grinding components at the output end of the grinder, it is easy to adjust the parameters of the drill bit's point angle, back angle, or helix angle, achieving precise, controllable, and repeatable processing of the drill bit's key geometric parameters, thus avoiding the problems of inconsistent angles and error accumulation in traditional manual grinding.

[0023] 3. In this invention, the moving frame is moved to the right to a suitable position so that the U-shaped block contacts the limiting mechanism. With the cooperation of the limiting mechanism, when the moving frame moves to the left, it pulls the limiting mechanism and the moving plate to the right, opening and closing the collection cavity inside the workbench. This achieves directional collection and closed storage of debris, thereby reducing the impact of debris on the operating accuracy and stability of the geometric parameter control mechanism, and facilitating subsequent unified cleaning and maintenance.

[0024] 4. The present invention features a telescopic plate that can extend and retract to accommodate the movement of the moving frame. The airbag is fixed to the fixed frame and connected to the moving frame, allowing it to be compressed as the moving frame moves to the right. The airbag is then discharged through an exhaust pipe that is angled to the right, facilitating the exhaust pipe to clean the lead screw with air. This prevents impurities from accumulating and affecting the smoothness of the lead screw transmission and positioning accuracy, thereby improving the stability and long-term reliability of the moving mechanism during drill bit geometry parameter adjustment.

[0037] The technical solution of the present invention will now be clearly and completely described 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.

[0038] Please see the appendix Figure 1 -Appendix Figure 3 This invention provides an intelligent precision machining device for controlling the geometric parameters of a drill bit, including a worktable 1. A drive box 2, a fixed frame 5, and a control box 11 are mounted on the upper surface of the worktable 1. A power shaft is provided inside the drive box 2 and connected to a chuck. An electric slide 3 is mounted on the upper side of the worktable 1. A limiter 4 is fixedly connected to the upper surface of the electric slide 3. A motor 6 is installed inside the worktable 1. The output end of the motor 6 passes through the interior of the fixed frame 5 and is fixedly mounted with a lead screw 7. Both ends of the lead screw 7 are rotatably connected to the interior of the fixed frame 5. A movable frame 8 is threadedly connected to the outer wall of the lead screw 7. A rotating component 9 is provided inside the movable frame 8. A grinder 10 is provided on the upper side of the rotating component 9. A transmission mechanism 12 is provided on the outer wall of the movable frame 8. A cleaning frame 13 is provided on the transmission mechanism 12.

[0039] Specifically, the limiting component 4 is equipped with a driving component and a center point. The driving component drives the center point to move and contact the drill bit away from the chuck, thereby limiting the rotation of the drill bit. The driving components of the drive box 2, the electric slide 3, the motor 6, the driving components of the moving frame 8, the driving components of the rotating component 9, and the driving components of the grinder 10 are all electrically connected to the control box 11, which facilitates the control of the above components by the control box 11. At the same time, different driving components, i.e., grinding components, can be installed and removed at the output end of the grinder 10. The drill bit can be fixed by the chuck. The position and angle of the grinder 10 are controlled by the control box 11, and the top angle, back angle, or helix angle of the drill bit can be adjusted, thereby realizing the processing and geometric parameter control of the drill bit. The transmission mechanism 12 moves with the moving frame 8. When the transmission mechanism 12 moves to the appropriate position, it connects with the cleaning frame 13, thereby driving the cleaning frame 13 to clean the lower side of the chuck and the processing area. No additional manual cleaning steps are required, realizing the integration of processing and cleaning, and avoiding processing interruption caused by manual cleaning.

[0040] Please see the appendix Figure 1 -Appendix Figure 4 The transmission mechanism 12 includes a support rod 121. The rear outer wall of the support rod 121 is fixedly connected to the front outer wall of the movable frame 8. The outer wall of the support rod 121 is rotatably connected to a fixed plate 122. The inside of the fixed plate 122 is slidably connected to a roller frame 123. The rollers of the roller frame 123 are slidably connected to a trapezoidal block 124. The outer wall of the trapezoidal block 124 is fixedly connected to the upper surface of the movable frame 8.

[0041] Specifically, the rotation of the fixed plate 122 is supported by the fixed support rod 121. The roller frame 123 is composed of a support frame and rollers. The outer wall of the movable frame 8 is provided with a short plate to facilitate the movement of the roller frame 123. The fixed plate 122 has a groove inside to allow the roller frame 123 to slide, which facilitates its cooperation with the trapezoidal block 124, so that the fixed plate 122 can rotate in a suitable position.

[0042] Please see the appendix Figure 3 -Appendix Figure 5 An iron block 125 is slidably connected inside the fixing plate 122. An elastic element 126 is connected between the iron block 125 and the fixing plate 122. A magnetic block 14 is provided on the lower side of the iron block 125. The iron block 125 is magnetically attracted to the magnetic block 14. The outer wall of the magnetic block 14 is fixedly connected to the outer wall of the cleaning frame 13.

[0043] Specifically, the iron block 125 is connected to the fixed plate 122 by the elastic element 126. This not only limits the range of movement of the iron block 125, but also allows the iron block 125 to move downwards by means of the reset elastic force and the magnetic block 14 to magnetically attract the iron block 125. This causes the fixed plate 122 and the slide bar 25 to form an L-shape, which limits the sweeping frame 13 so that the movement of the fixed plate 122 can drive the sweeping frame 13 to move.

[0044] Please see the appendix Figure 4 The lower surface of the cleaning frame 13 is slidably connected to the upper surface of the workbench 1. A connecting frame 15 is fixedly connected to the outer wall of the cleaning frame 13. The outer wall of the connecting frame 15 is slidably connected between the workbench 1 and the drive box 2. A telescopic rod 16 is connected between the connecting frame 15 and the drive box 2. One end of a tension spring 17 is fixedly connected to the outer wall of the connecting frame 15. The other end of the tension spring 17 is fixedly connected to the inside of the drive box 2.

[0045] Specifically, the central component of the cleaning frame 13 is designed to be conical and elastic, which facilitates the movement of debris at the center to both sides. At the same time, it adapts to the movement of the cleaning frame 13 itself. The cleaning frame 13 slides on the upper surface of the worktable 1, which facilitates the cleaning of debris under the chuck and in the processing area. The initial position of the cleaning frame 13 is located under the chuck and close to the drive box 2, which prevents debris from appearing between the cleaning frame 13 and the drive box 2. The interior of the drive box 2 and the upper surface of the worktable 1 facilitate the offset restriction of the movement of the connecting frame 15. The extension rod 16 limits the range of movement of the connecting frame 15, and the tension spring 17 provides a restoring force after the connecting frame 15 moves to the left.

[0046] Please see the appendix Figure 6 -Appendix Figure 9 A U-shaped block 18 is fixedly connected to the outer wall of the movable frame 8. A magnetic block 23 is fixedly connected inside the U-shaped block 18. A limiting mechanism 19 is provided on the inner side of the U-shaped block 18. The limiting mechanism 19 includes a connecting block 191. The outer wall of the connecting block 191 is located inside the U-shaped block 18. A movable plate 20 is fixedly connected to the lower surface of the connecting block 191. The outer wall of the movable plate 20 is slidably connected inside the worktable 1.

[0047] Specifically, the movable plates 20 are set on the front and rear sides of the worktable 1, and the connecting blocks 191 are connected to the movable plates 20 on both sides near the center, so that the movable plates 20 can be pushed to move as the limiting mechanism 19 moves. The interior of the connecting blocks 191 is hollow, so that the internal components of the connecting blocks 191 can move.

[0048] Please see the appendix Figure 8A convex block 192 is slidably connected inside the connecting block 191. An I-shaped frame 193 is rotatably connected inside the convex block 192. A transmission frame 21 is rotatably connected to the outer wall of the I-shaped frame 193. The outer wall of the transmission frame 21 is slidably connected inside the connecting block 191. An iron rod 194 is fixedly connected to the upper surface of the convex block 192. The iron rod 194 is magnetically attracted to the magnetic block 23.

[0049] Specifically, the convex block 192 slides inside the connecting block 191 via its rear outer wall, thereby restricting the movement of the convex block 192. The I-beam frame 193, composed of a connecting plate and short rods on both sides, is easily moved by the transmission frame 21 to transmit power to the convex block 192. The iron rod 194 is attracted by the magnetic block 23, which helps the iron rod 194 to be pushed closer to the magnetic block 23 by the convex block 192.

[0050] Please see the appendix Figure 6 -Appendix Figure 9 The transmission frame 21 is located on the outer wall of the fixed frame 5 on the side away from the connecting block 191, and a telescopic member 22 is connected between the transmission frame 21 and the fixed frame 5.

[0051] Specifically, the transmission frame 21 is initially close to the fixed frame 5, and the short plate on the right side of the transmission frame 21 contacts the fixed frame 5, thereby limiting the rightward movement of the transmission frame 21. The extension member 22 is used to limit the range of leftward movement of the transmission frame 21.

[0052] Please see the appendix Figure 10 Both sides of the movable plate 20 have U-shaped rods 24 fixedly connected to their lower surfaces. One end of a spring 26 is fixedly connected to the outer wall of the U-shaped rod 24, and the other end of the spring 26 is fixedly connected to the inside of the worktable 1. A slide rod 25 is fixedly connected to the inside of the U-shaped rod 24, and the outer wall of the slide rod 25 is slidably connected to the inside of the worktable 1.

[0053] Specifically, the two movable plates 20 on both sides are connected by the U-shaped rod 24 to facilitate synchronous movement of the two movable plates 20. The spring 26 provides a reset force for the movable plates 20 to ensure stable reset. The movement of the slide rod 25 is restricted by the inside of the worktable 1, and the slide rod 25 limits the movement of the U-shaped rod 24.

[0054] Please see the appendix Figure 10 A telescopic plate 27 is connected between the fixed frame 5 and the movable frame 8. An airbag 28 is provided on the lower side of the telescopic plate 27. The outer wall of the airbag 28 is fixedly connected to the outer wall of the fixed frame 5. An exhaust pipe 29 is installed inside the airbag 28. An air inlet pipe 30 is installed inside the airbag 28 and penetrates the interior of the fixed frame 5.

[0055] Specifically, the telescopic plate 27 connects the fixed frame 5 and the movable frame 8, blocking the gap between the fixed frame 5 and the movable frame 8 to prevent processing debris from entering the inside of the fixed frame 5. It also protects the airbag 28. The exhaust pipe 29 and the air inlet pipe 30 facilitate the compression or release of the airbag 28 as the movable frame 8 moves, thereby realizing the inflation and deflation actions. The exhaust pipe 29 sprays air to the drive component that drives the movable frame 8 to remove debris, preventing debris from affecting the movement of the movable frame 8.

[0056] Please see the appendix Figure 1 -Appendix Figure 11 A method for controlling the geometric parameters of an intelligent precision machining device for controlling the geometric parameters of drill bits. The method includes the following steps:

[0057] S1. The drill bit to be processed is clamped on the chuck connected to the power shaft inside the drive box 2. The chuck is used to achieve axial positioning and clamping of the drill bit. Then, the electric slide 3 is started so that the limiting component 4 can assist in limiting the position of the drill bit.

[0058] S2. Start the motor 6 inside the worktable 1 to drive the lead screw 7 to rotate, so that the moving frame 8 moves linearly along the direction of the fixed frame 5. Through the displacement of the moving frame, the position of the grinding machine 10 in the axial and radial directions can be adjusted, providing a motion basis for the control of the drill bit geometry parameters.

[0059] S3. During the movement of the moving frame 8, the rotating component 9 drives the grinding machine 10 to change its position and posture relative to the drill bit, so that the grinding component of the grinding machine 10 and the cutting edge of the drill bit form a preset relative angle and contact position, thereby accurately grinding the geometric parameters of the drill bit. The control box 11 controls the motor 6, the lead screw 7 and the electric slide 3 to achieve smooth feed and controllable adjustment during the geometric parameter adjustment process.

[0060] Workflow: The drill bit is placed in the center of the chuck in the drive box 2 and controlled by the control box 11. The chuck fixes the drill bit. The drive components and power shaft inside the drive box 2 cause the chuck and drill bit to rotate. When it is necessary to adjust the point angle, clearance angle or helix angle of the drill bit, the limiter 4 moves away from the drill bit. The grinder 10 rotates to the appropriate position so that the grinding components of the grinder 10 contact the point angle, clearance angle or helix angle of the drill bit, thereby adjusting the point angle, clearance angle or helix angle of the drill bit.

[0061] After the drill bit is processed, the resulting debris falls to the lower side of the chuck. The moving frame 8 moves to the right to a suitable position, so that the fixed plate 122 contacts the cleaning frame 13. The magnetic attraction of the magnetic block 14 on the right side of the cleaning frame 13 causes the iron block 125 to move downward, deforming the elastic element 126. The moving frame 8 moves to the left, and the iron block 125 and the fixed plate 122 form an L-shape, pulling the cleaning frame 13 to the left to clean the debris on the lower side of the drive box 2. The connecting frame 15 stretches the tension spring 17. When the roller frame 123 contacts the trapezoidal block 124, it pushes against the fixed plate 122 and rotates under the action of the support rod 121. This causes the iron block 125 to move away from the cleaning frame 13, no longer limiting the cleaning frame 13, and facilitating the reset of the cleaning frame 13 and the connecting frame 15 under the tension of the tension spring 17.

[0062] When cleaning the debris on the lower side of the drive box 2, the moving frame 8 is moved to the right to a suitable position, so that the U-shaped block 18 contacts the limiting mechanism 19. The moving frame 8 continues to move to the right, pushing the U-shaped block 18 and the limiting mechanism 19 to move to the right. The right side of the transmission frame 21 abuts against the fixed frame 5, so that the transmission frame 21 slides inside the connecting block 191, causing the I-shaped frames 193 on both sides to open up and down. The convex block 192 pushes the iron rod 194 to move. Since the magnetic block 23 magnetically attracts the iron rod 194, the iron rod 194 passes through the interior of the connecting block 191 and enters the interior of the U-shaped block 18, so that when the moving frame 8 moves to the left, it drives the limiting mechanism 194. 9 and the moving plate 20 move to the left, and the U-shaped rod 24 squeezes the spring 26 to open the collection cavity inside the workbench 1, so that the cleaning frame 13 can clean the debris under the drive box 2 and collect the debris for subsequent processing. When the moving frame 8 moves to the left to the appropriate position, the telescopic member 22 limits the movement of the transmission frame 21, thereby pulling the transmission frame 21 to the right inside the connecting block 191. After passing the I-shaped frame 193 and the convex block 192, the iron rod 194 slides into the inside of the connecting block 191, so that the U-shaped block 18 and the limiting mechanism 19 can separate. Under the elastic force of the spring 26, the moving plate 20 and the limiting mechanism 19 are reset.

[0063] The telescopic plate 27 is connected to the movable frame 8 and the fixed frame 5, and the telescopic plate 27 itself can extend and retract to adapt to the movement of the movable frame 8. The airbag 28 is fixed to the fixed frame 5 and connected to the movable frame 8, so that the airbag 28 can be squeezed as the movable frame 8 moves to the right. The exhaust pipe 29 is set at an angle and faces to the right, so that the exhaust pipe 29 can spray air to clean the lead screw 7, so as to avoid debris affecting the lead screw 7 to drive the movable frame 8 to move, thus improving the stability of the movable frame 8 during use.

[0064] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
