Description

Technical Field

[0001] This utility model relates to the field of physical vapor deposition technology, and in particular to a three-dimensional rotary table for drill bit processing. Background Technology

[0002] Physical vapor deposition (PVD) technology uses physical means to heat and vaporize or ionize coating materials in a vacuum environment, causing them to deposit on the drill bit surface to form a thin film. This technology can impart excellent wear resistance, corrosion resistance, and lubrication properties to drill bits without altering the properties of the drill bit substrate material, significantly improving drill bit lifespan and cutting efficiency. The coating layer formed on the drill bit surface has strong adhesion to the substrate, effectively reducing frictional resistance during cutting and minimizing cutting heat generation, thereby improving machining accuracy and surface quality.

[0003] Currently, when using physical vapor deposition (PVD) to coat drill bits, a three-dimensional turntable is typically used to rotate the drill bit at multiple angles to ensure uniform coating on complex structures such as grooves and spiral flutes, allowing the coating material to fully cover all surfaces. However, during the drill bit fixing process, the contact area between the drill bit and the fixing mechanism may be blocked and unable to be coated. These uncoated areas are prone to wear or corrosion during subsequent use, affecting the overall performance of the drill bit. Therefore, to ensure the integrity of the coating on the drill bit surface, secondary coating treatment is often required for these areas, which not only increases the complexity of the process but also consumes a significant amount of time and labor costs, reducing production efficiency.

[0004] Based on the above viewpoints, those skilled in the art provide a three-dimensional rotary table for drill bit machining. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

A turntable base 3 is rotatably connected inside the fixed outer shell 1. A lifting bracket 4 is slidably connected to the top of the turntable base 3. A drill bit mounting assembly 6 is rotatably connected inside the lifting bracket 4. The drill bit mounting assembly 6 includes a motor mounting bracket 62. A drill bit drive motor 63 is mounted on the left side wall of the motor mounting bracket 62. The movable end of the drill bit drive motor 63 passes through the motor mounting bracket 62 and is fixedly connected to a drill bit placement plate 64. An electric cylinder mounting bracket 65 is fixedly connected to the left side wall of the motor mounting bracket 62 and located on the outer side wall of the drill bit drive motor 63. A fixed electric cylinder 66 is mounted at the middle position of the left inner wall of the electric cylinder mounting bracket 65. The movable end of the fixed electric cylinder 66 passes through the left side wall of the electric cylinder mounting bracket 65 and is fixedly connected to a tail plate 67. A plurality of connecting rods 68 are fixedly connected to the right side wall of the tail plate 67. A fixing ring 69 is fixedly connected to the other end of the plurality of connecting rods 68.

[0025] The three-dimensional turntable places the drill bit that needs PVD coating through the drill bit mounting assembly 6. When placing the drill bit, the drill bit is placed between the drill bit mounting plate 64 and the coating notch 610. Then, the fixing electric cylinder 66 is activated. When the movable end of the fixing electric cylinder 66 extends, it will drive the fixing ring 69 to move towards the drill bit mounting plate 64 through the tail plate 67 and several connecting rods 68, thereby pressing and fixing the drill bit in the drill bit mounting assembly 6. Then, the drill bit drive motor 63 drives the drill bit mounting plate 64 to rotate, thereby driving the drill bit to rotate in the drill bit mounting assembly 6, so as to achieve full coating of the drill bit.

[0026] A coating notch 610 is provided on the fixing ring 69, and several connecting rods 68 pass through the motor mounting bracket 62. The motor mounting bracket 62 provides intermediate support for the connecting rods 68, preventing deformation of the motor mounting bracket 62. The coating notch 610 creates a coating space for the drill bit, preventing the fixing ring 69 from obstructing the drill bit. An angle adjustment motor 5 is installed on the front side wall of the lifting bracket 4. The movable end of the angle adjustment motor 5 passes through the lifting bracket 4 and connects to the drill bit mounting assembly 6. The angle adjustment motor 5 can drive the drill bit mounting assembly 6 to rotate, thereby making the tip of the drill bit face upward, achieving coating on the tip of the drill bit. At the same time, the angle adjustment motor 5 can drive the drill bit to tilt at a certain angle, preventing uneven coating caused by overlapping and obstruction at the grooves on the drill bit.

[0027] The drill bit mounting assembly 6 also includes a connecting frame 61, which is fixed on the left side wall of the motor mounting bracket 62. The drill bit mounting assembly 6 is connected to the movable end of the angle adjustment motor 5 through the connecting frame 61.

An external gear 10 is fixedly connected to the outer side wall of the turntable base 3, and the adjusting gear 9 meshes with the external gear 10. The platform motor 2 can drive the turntable base 3, which meshes with it, to rotate via the adjusting gear 9, thereby adjusting the circumferential coating position. A height adjusting electric cylinder 7 is installed at the center of the lower side wall of the fixed housing 1. A rotating joint 8 is rotatably connected to the movable end of the height adjusting electric cylinder 7, and the rotating joint 8 is fixedly connected to the lower side wall of the lifting bracket 4. The height adjusting electric cylinder 7 can drive the lifting bracket 4 to move up and down, thereby driving the drill bit in the drill bit mounting assembly 6 to adjust its height, ensuring the uniformity of the coating.

[0029] Working principle: The three-dimensional turntable places the drill bit requiring PVD coating through the drill bit mounting assembly 6. During placement, the drill bit is positioned between the drill bit mounting plate 64 and the coating notch 610. Then, the fixing cylinder 66 is activated. When the movable end of the fixing cylinder 66 extends, it drives the fixing ring 69 towards the drill bit mounting plate 64 via the tail plate 67 and several connecting rods 68, thereby pressing and fixing the drill bit within the drill bit mounting assembly 6. Subsequently, the drill bit drive motor 63 drives the drill bit mounting plate 64 to rotate, which in turn drives the drill bit to rotate within the drill bit mounting assembly 6, achieving full coating of the drill bit. Simultaneously, the coating notch 610 opens up the coating area for the drill bit. The membrane space prevents the fixing ring 69 from obstructing the drill bit. The angle adjustment motor 5 can drive the drill bit mounting assembly 6 to rotate, so that the tip of the drill bit faces upward, achieving coating on the tip of the drill bit. At the same time, the angle adjustment motor 5 can drive the drill bit to tilt at a certain angle, avoiding uneven coating caused by overlapping and obstruction at the grooves on the drill bit. The platform motor 2 can drive the turntable base 3 meshing with it to rotate through the adjustment gear 9, thereby adjusting the circumferential coating position. The height adjustment electric cylinder 7 can drive the lifting bracket 4 to move up and down, thereby adjusting the height of the drill bit in the drill bit mounting assembly 6 to ensure the uniformity of the coating.
