Description

Technical Field

[0001] This utility model relates to the field of high-precision drill bit processing technology, and in particular to a cutting device for high-precision drill bit processing. Background Technology

[0002] Drill bits, as a common cutting tool, are widely used in machining, oil drilling, and other fields. Traditional drill bit processing equipment typically only cuts in the horizontal, vertical, or back-and-forth directions, limiting processing flexibility and precision. In practical applications, many drill bits require the machining of bevel angles to meet specific process requirements, but existing cutting equipment often lacks the capability to precisely machine bevel angles. Therefore, achieving automated and high-precision machining of drill bit bevel angles has become crucial for improving drill bit processing efficiency and accuracy.

[0003] For example, Chinese Utility Model Patent Application No. 202322963330.8 discloses a cutting device for high-precision drill bit processing, including a body. A support column is fixedly installed on one side of the upper end of the body. A first motor is fixedly installed in the middle of the upper end of the support column. A first lead screw is fixedly connected to the output end of the first motor. A first sliding seat is slidably sleeved on the outer wall of the first lead screw. A base is fixedly installed on one side wall of the first sliding seat. A second motor is fixedly installed on one side wall of the body. This utility model provides a cutting device for high-precision drill bit processing that facilitates position adjustment for cutting. It also facilitates clamping and fixing, as well as waste chip disposal, solving the problems of cumbersome position adjustment and inconvenient waste chip disposal in existing high-precision drill bit processing cutting devices.

[0004] While the clamping device described above can secure the drill bit, in practical use, this method can easily cause imbalance during cutting, leading to significant machining errors. Furthermore, traditional drill bit clamping methods mostly rely on manual adjustment or simple fixing mechanisms. When machining at angles, manual adjustment of the drill bit or machining equipment is usually required, resulting in problems such as difficulty in ensuring accuracy, complex operation, and low efficiency. Therefore, a high-precision drill bit machining cutting device is proposed to solve these problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a cutting device for high-precision drill bit processing.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a cutting device for high-precision drill bit processing, including a processing table, a clamping box fixedly connected to the inner bottom surface of the processing table, a rotating shaft rotatably connected inside the clamping box, one end of the rotating shaft rotatably passing through to the outside of the clamping box and fixedly connected to a clamping frame, a rotating component arranged inside the clamping box, two clamping blocks slidably connected to the inner wall of the clamping frame, an arc-shaped plate fixedly connected to one side of the clamping block, a clamping component arranged inside the clamping frame, an auxiliary component arranged between the tops of the two arc-shaped plates, a moving component arranged between the two sides of the inner wall of the processing table, a support plate arranged at one end of the moving component, a rotating shaft rotatably connected to the top of the support plate, a steering component arranged at the top of the support plate, an inclined box fixedly connected to the top of the rotating shaft, a rotating shaft rotatably connected inside the inclined box, one end of the rotating shaft rotatably passing through to the outside of the inclined box and fixedly connected to a cutting blade, and a driving component arranged inside the inclined box.

[0007] The clamping box houses and secures the rotating shaft and rotating components, ensuring a stable and rotatable clamping system during drill bit processing. The rotating shaft primarily supports the rotation of the clamping frame, allowing the clamping frame to rotate the drill bit for cutting. The arc-shaped plate assists in clamping the drill bit, forming a stable clamping system in conjunction with the clamping block to prevent the drill bit from loosening during processing.

The bidirectional threaded rod controls the sliding of the clamping blocks by rotation, thereby adjusting the clamping tightness of the drill bit. The rotary knob is used to adjust the rotation of the bidirectional threaded rod, so that the clamping blocks move inward or outward, clamping or releasing the drill bit.

[0014] As a further description of the above technical solution:

[0015] The auxiliary component includes an auxiliary screw threaded inside two arc-shaped plates, and a fixing nut is threaded onto the outer wall of the auxiliary screw.

[0016] The auxiliary components are used to further enhance the fixation of the drill bit, especially when the drill bit diameter is large, they can provide additional clamping force to ensure that the drill bit does not loosen due to its excessive size.

[0019] The telescopic end of the electric telescopic rod is fixedly connected to the support plate. The electric slide rail system can move the support plate up, down, left, and right within the processing table, providing a more flexible positioning function and adapting to drill bits of different sizes.

[0020] As a further description of the above technical solution:

[0021] The steering assembly includes an electric telescopic rod II fixedly installed on the top of the support plate. The telescopic end of the electric telescopic rod II is fixedly connected to a rack, and the outer wall of the rack is meshed with a gear III.

[0022] The gear three is fixedly connected to the rotating shaft and is used to adjust the rotation angle of the rotating shaft, thereby adjusting the angle of the tilting box and ensuring that the cutting blade can work at multiple angles.

[0023] As a further description of the above technical solution:

[0024] The drive assembly includes a servo motor fixedly installed on the inner wall of the tilting box, and a worm gear is fixedly connected to the output end of the servo motor.

[0025] One end of the worm gear is rotatably connected to the top surface inside the tilting box. The worm gear meshes with the worm wheel to provide a precise angle adjustment function, controlling the rotation angle of the rotating shaft, thereby adjusting the cutting angle of the cutting blade and achieving high-precision cutting operation.

[0026] As a further description of the above technical solution:

[0027] The outer wall of the worm is meshed with a worm wheel.

[0028] The inside of the worm gear is fixedly connected to the rotating shaft.

Detailed Implementation

[0038] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0039] According to one embodiment of the present invention, in conjunction with Figure 1-5A high-precision drill bit machining cutting device is shown. It includes a machining table 1, a clamping box 2 fixedly connected to the inner bottom surface of the machining table 1, a rotating shaft 3 rotatably connected inside the clamping box 2, one end of the rotating shaft 3 rotatably extending to the outside of the clamping box 2 and fixedly connected to a clamping frame 4, a rotating assembly inside the clamping box 2, two clamping blocks 5 slidably connected to the inner wall of the clamping frame 4, an arc-shaped plate 6 fixedly connected to one side of each clamping block 5, a clamping assembly inside the clamping frame 4, an auxiliary assembly between the tops of the two arc-shaped plates 6, and a moving assembly between the two sides of the inner wall of the machining table 1. A support plate 7 is provided at one end of the moving component. A rotating shaft 8 is rotatably connected to the top of the support plate 7. A steering component is provided at the top of the support plate 7. An inclined box 9 is fixedly connected to the top of the rotating shaft 8. A rotary shaft 10 is rotatably connected inside the inclined box 9. One end of the rotary shaft 10 rotatably extends to the outside of the inclined box 9 and is fixedly connected to a cutting blade 11. A drive component is provided inside the inclined box 9. The clamping box 2 is responsible for accommodating and fixing the rotating shaft 3 and the rotating component, ensuring the stability and rotatability of the clamping system during drill bit processing. The main function of the rotating shaft 3 is to support the rotation of the clamping frame 4. The rotation of the rotating shaft 3 causes the clamping frame 4 to rotate, adapting it to the cutting process. The arc-shaped plate 6 provides auxiliary clamping for the drill bit, forming a stable clamping system in conjunction with the clamping block 5 to ensure the drill bit does not loosen during processing. The rotating shaft 8 connects the support plate 7 and the tilting box 9, supporting and rotating the tilting box 9, thereby controlling the rotation of the cutting blade 11. The tilting box 9 provides an adjustment function for the angle of the cutting blade 11. Combined with the rotating shaft 10 and the servo motor 25, the tilting box 9 can precisely control the tilt angle of the cutting blade 11 for oblique cutting. The operation involves the coordinated use of structures such as the clamping frame 4, clamping components, rotating components, and auxiliary components. The clamping motor 12, gear system, and rotating shaft 3 drive the clamping frame 4 to rotate, enabling automatic rotation of the drill bit. This reduces manual operation and ensures that the drill bit can cut evenly at all angles during the cutting process, avoiding cutting imbalance caused by uneven rotation, thereby improving processing accuracy. At the same time, when the diameter of the raw material to be processed is large, the auxiliary components can effectively reinforce the clamping, preventing the drill bit from loosening during processing and causing processing errors, thus ensuring processing accuracy.

[0040] The rotating assembly includes a clamping motor 12 fixedly installed inside the clamping box 2. The output end of the clamping motor 12 is fixedly connected to a gear 13. The outer wall of the gear 13 is meshed with a gear 14. One side of the gear 14 is fixedly connected to one end of the rotating shaft 3. The rotating assembly is used to drive the rotating shaft 3 to rotate. Through the drive of the clamping motor 12, the gear system transmits power to make the rotating shaft 3 rotate, thereby driving the clamping frame 4 to rotate, thus realizing the rotation of the drill bit.

[0041] The clamping assembly includes a bidirectional threaded rod 15 rotatably mounted on the inner wall of the clamping frame 4. One end of the bidirectional threaded rod 15 rotatably extends to the outside of the clamping frame 4 and is fixedly connected to a rotary knob 16. The outer wall of the bidirectional threaded rod 15 is threadedly connected to the inside of two clamping blocks 5. The bidirectional threaded rod 15 controls the sliding of the clamping blocks 5 by rotation, thereby adjusting the clamping tightness of the drill bit. The rotary knob 16 is used to adjust the rotation of the bidirectional threaded rod 15, causing the clamping blocks 5 to move inward or outward, clamping or releasing the drill bit. The auxiliary assembly includes an auxiliary screw 17 threadedly connected inside two arc-shaped plates 6. The outer wall of the auxiliary screw 17 is threadedly connected to a fixing nut 18. The auxiliary assembly is used to further enhance the fixation of the drill bit, especially when the drill bit diameter is large, it can provide additional clamping force to ensure that the drill bit will not loosen due to excessive size.

[0042] The moving component includes an electric slide rail 19 fixedly installed between the two sides of the inner wall of the processing table 1. An electric slide rail 20 is fixedly connected inside the electric slide rail 19 via an electric slider. An electric telescopic rod 21 is fixedly connected inside the electric slide rail 20 via an electric slider. The telescopic end of the electric telescopic rod 21 is fixedly connected to the support plate 7. The electric slide rail system can move the support plate 7 up, down, left, and right within the processing table 1, providing a more flexible positioning function and adapting to drill bits of different sizes.

[0043] The steering assembly includes an electric telescopic rod 22 fixedly mounted on the top of the support plate 7. The telescopic end of the electric telescopic rod 22 is fixedly connected to a rack 23. The outer wall of the rack 23 is meshed with a gear 24. The inside of the gear 24 is fixedly connected to the rotating shaft 8 and is used to adjust the rotation angle of the rotating shaft 8, thereby adjusting the angle of the tilting box 9 and ensuring that the cutting blade 11 can work at multiple angles.

[0044] The drive assembly includes a servo motor 25 fixedly mounted on the inner wall of the tilting box 9. The output end of the servo motor 25 is fixedly connected to a worm gear 26. One end of the worm gear 26 is rotatably connected to the inner top surface of the tilting box 9. The worm gear 26 provides a precise angle adjustment function by meshing with a worm wheel 27, controlling the rotation angle of the rotating shaft 10, thereby adjusting the cutting angle of the cutting blade 11 and achieving high-precision cutting operation. The outer wall of the worm gear 26 is meshed with a worm wheel 27, and the inside of the worm wheel 27 is fixedly connected to the rotating shaft 10.

[0045] The working principle of this embodiment is as follows: First, the raw material to be cut is placed between two arc-shaped plates 6. Then, the rotary knob 16 is rotated to rotate the bidirectional threaded rod 15, which in turn allows the two clamping blocks 5 to move along the inside of the clamping frame 4, so that the arc-shaped plates 6 can fix the drill bit. At the same time, when the diameter of the raw material to be processed is large, the auxiliary screw 17 can be threaded through the two arc-shaped plates 6 through the auxiliary component, and then the fixing nut 18 can be screwed on the auxiliary screw 17 to further fix the clamped material. When cutting is required, the clamping motor 12 can be started, and the output end rotates to drive the gear 13 to rotate, which in turn drives the gear 2 14 to rotate, which in turn drives the rotating shaft 3 to rotate, which in turn rotates the clamping frame 4, and thus the raw material to be cut rotates. At this time, the position of the cutting blade 11 can be adjusted to perform milling, thereby processing the drill bit. This ensures the stability and accuracy of the drill bit processing and avoids processing errors caused by uneven drill bit rotation or unbalanced cutting.

[0046] Simultaneously, when cutting with the drill bit, if side cutting or tilting to form an arc angle is required, the electric slide rail 19 and electric slide rail 20 can be activated to allow the cutting blade 11 to move horizontally and vertically. Once it reaches the appropriate position, the electric telescopic rod 21 can be activated to allow the support plate 7 to move back and forth. Then, the electric telescopic rod 22 can be activated, and its telescopic end drives the rack 23 to move, causing the rack 23 to drive the gear 24 meshing with it to rotate. When the gear 24 rotates, it drives the rotating shaft 8 to rotate, allowing the tilting box 9 to rotate. Then, the servo motor 25 is activated, and its output end rotates to drive the worm gear 26 to rotate, causing the worm gear 26 to drive the worm wheel 27 meshing with it to rotate, thereby tilting the rotating shaft 10 at an angle, allowing the cutting blade 11 to cut at an angle. Unlike traditional equipment, this device can not only cut in the traditional horizontal, vertical, and forward / backward directions, but also tilt and rotate in multiple axes, greatly improving the accuracy and efficiency of drill bit processing.

[0047] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
