Description
Technical Field
[0001] This application belongs to the field of machining technology, specifically a tooth-making structure. Background Technology
[0002] Fence structures are widely used in high-end equipment such as aero engines and gas turbines, primarily for sealing, reducing gas leakage, and improving equipment efficiency and performance. However, traditional fence machining methods have several problems. When machining fence-like parts on a conventional lathe, the cutter head is subjected to force on only one side. During the feed process, this can cause the cutter head to deform, easily resulting in poor machining accuracy and requiring frequent tool replacements, leading to high production costs for enterprises. Utility Model Content
[0003] The purpose of this application is to provide a tooth-making structure in order to solve the problems mentioned above.
[0004] The technical solution adopted in this application is as follows: A tooth-cutting structure includes an equipment housing, and further includes a lead screw, a sliding fixing block, an adjustable stroke cylinder, a linear-to-rotation mechanism, a spherical cutter head, a part fixing component, and a drive motor located within the equipment housing; the lead screw is horizontally arranged and rotatably connected to the inner wall of the equipment housing, the outer side of the lead screw is threadedly connected to the sliding fixing block, the adjustable stroke cylinder is vertically arranged and its fixed end is connected to the sliding fixing block, the free end of the adjustable stroke cylinder is driven by the linear-to-rotation mechanism, the linear-to-rotation mechanism is connected to the spherical cutter head, and is used to convert the linear drive motion of the adjustable stroke cylinder into rotational and linear drive motion of the spherical cutter head; the part fixing component is used to fix the part to be processed, and the drive motor is used to drive the part fixing component to rotate.
[0005] In the technical solution of this application, the lead screw and the sliding fixed block are threaded together. Rotation of the lead screw drives the sliding fixed block to move linearly along the lead screw, which in turn drives the adjustable stroke cylinder, the linear-to-rotation mechanism, and the ball cutter head to move linearly along the lead screw, allowing the ball cutter head to move closer to or further away from the workpiece. The drive motor drives the workpiece fixing component and the workpiece to rotate at high speed. When the ball cutter head contacts the high-speed rotating workpiece, the cutting operation on the workpiece can be achieved. Furthermore, the linear-to-rotation transmission mechanism allows the adjustable stroke cylinder to move vertically... The linear drive motion is transformed into both linear and rotational drive actions. That is, by using a linear-to-rotational transmission mechanism to convert the transmission action, the ball cutter head can be driven to move linearly along its own axis while simultaneously rotating around its own axis. In this way, when cutting the workpiece, not only can the ball cutter head achieve the cutting feed action, but it can also rotate, thereby driving the ball cutter head to perform rotary turning around its own axis. This ensures that all four sides of the ball cutter head participate in the cutting process, improving tool life, reducing enterprise production costs, and increasing equipment production efficiency.
[0006] In a preferred embodiment, the linear variable rotary transmission mechanism includes a lower pressure block, a connecting rod, a fixed plate, and a rotating column; the free end of the adjustable stroke cylinder is fixedly connected to the lower pressure block and is used to drive the lower pressure block to move up and down; the fixed plate is spaced below the sliding fixed block and connected to the sliding fixed block through the connecting rod; the fixed plate has a through hole and a protrusion located in the through hole; the outer peripheral wall of the rotating column has a spiral slide; the rotating column passes through the through hole, and the spiral slide of the rotating column slides in cooperation with the protrusion in the through hole; the upper end of the rotating column is rotatably connected to the lower pressure block, and the lower end of the rotating column is connected to the spherical cutter head.
[0007] In a preferred embodiment, an annular boss is provided below the pressing block, and an annular groove is provided on the inner side of the annular boss. An annular shoulder is provided at the upper end of the rotating column, and the annular shoulder is slidably connected to the annular groove so that the pressing block and the rotating column can rotate relative to each other around the central axis of the rotating column.
[0008] In a preferred embodiment, a tool fixing groove is provided on the lower end face of the rotating column, a tool holder is detachably connected inside the tool fixing groove, and the spherical cutter head is fixedly connected below the tool holder.
[0009] In a preferred embodiment, the lead screw includes two lead screws arranged in parallel, and the sliding fixing block is threadedly engaged with both lead screws simultaneously.
[0010] In a preferred embodiment, the system further includes a transmission gear, a drive gear, and a translation motor. The transmission gear is fixedly sleeved on the outer side of the lead screw. The transmission gear meshes with the drive gear. The translation motor is connected to the drive gear and is used to drive the drive gear to rotate.
[0011] In a preferred embodiment, a glass door is rotatably connected to the front of the equipment housing, and a handle is fixedly connected to the outer side of the glass door.
[0012] In a preferred embodiment, an operation screen and operation buttons are fixedly connected to the outside of the device housing.
[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are: In this application, during the operation of the equipment, the adjustable stroke cylinder is activated to drive the lowering block to slowly descend. As the lowering block slowly descends, it passes through the spiral slide on the outside of the fixed rotating column below the limit block and the protrusion fixed on the inside of the through hole. Then, it passes through the annular boss and annular groove, which will drive the limit block to slowly descend and rotate. By operating the operation button and programming the equipment, the ball cutter head can be driven to rotate and turn, so that all four sides of the ball cutter head participate in cutting, thereby improving the tool life, reducing the enterprise's production costs, and improving the production efficiency of the equipment.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0017] Example: Reference Figure 1-6 A tooth-cutting structure includes a housing 1, and further includes a lead screw 2, a sliding fixing block 3, an adjustable stroke cylinder 4, a linear-to-rotation mechanism, a spherical cutter head 17, a part fixing component 22, and a drive motor 21 located within the housing 1. The lead screw 2 is horizontally arranged and rotatably connected to the inner wall of the housing 1. The outer side of the lead screw 2 is threadedly connected to the sliding fixing block 3. The adjustable stroke cylinder 4 is vertically arranged and its fixed end is connected to the sliding fixing block 3. The free end of the adjustable stroke cylinder 4 is driven by the linear-to-rotation mechanism. The linear-to-rotation mechanism is connected to the spherical cutter head 17 and is used to convert the linear drive motion of the adjustable stroke cylinder 4 into rotational and linear drive motion of the spherical cutter head 17. The part fixing component 22 is used to fix the part to be processed, and the drive motor 21 is used to drive the part fixing component 22 to rotate.
[0018] In this embodiment, the lead screw 2 is threadedly engaged with the sliding fixed block 3. Rotation of the lead screw 2 drives the sliding fixed block 3 to move linearly along the lead screw 2, which in turn drives the adjustable stroke cylinder 4, the linear variable rotation mechanism, and the ball cutter head 17 to move linearly along the lead screw 2, allowing the ball cutter head 17 to move closer to or further away from the workpiece. The drive motor 21 drives the workpiece fixing member 22 and the workpiece to rotate at high speed. Therefore, when the ball cutter head 17 contacts the high-speed rotating workpiece, the cutting operation on the workpiece can be achieved. Furthermore, the linear variable rotation transmission mechanism... The structure can convert the linear drive motion of the adjustable stroke cylinder 4 into the rotational motion of the spherical cutter head 17. That is, by using the conversion of the transmission action through the linear-to-rotary transmission mechanism, the spherical cutter head 17 can be driven to move linearly along its own axis while simultaneously rotating around its own axis. In this way, when cutting the workpiece, not only can the cutting feed action of the spherical cutter head 17 be realized, but the spherical cutter head 17 also rotates synchronously, so that all four sides of the spherical cutter head 17 participate in the cutting process, thereby improving the tool life, reducing enterprise production costs, and improving equipment production efficiency.
[0019] Optionally, refer to Figure 1-7 The linear-to-rotary transmission mechanism includes a lower pressure block 5, a connecting rod 8, a fixed plate 9, and a rotating column 13. The free end of the adjustable stroke cylinder 4 is fixedly connected to the lower pressure block 5 and is used to drive the lower pressure block 5 to move up and down. The fixed plate 9 is spaced below the sliding fixed block 3 and connected to the sliding fixed block 3 through the connecting rod 8. The fixed plate 9 has a through hole 11 and a protrusion located in the through hole 11. The outer peripheral wall of the rotating column 13 has a spiral slide 14. The rotating column 13 passes through the through hole, and the spiral slide 14 of the rotating column 13 is slidably engaged with the protrusion in the through hole 11. The upper end of the rotating column 13 is rotatably connected to the lower pressure block 5, and the lower end of the rotating column 13 is connected to the spherical cutter head 17.
[0020] In this embodiment, the part to be processed (generally a ring-shaped or cylindrical structure 26) is connected to the part fixing member 22, so that the axis of the part to be processed (i.e., the central axis of the ring-shaped or cylindrical structure 26) is horizontally set. The power motor 21 and the part fixing member 22 drive the part to be processed to rotate at high speed around its own axis. Then, the translation motor 20 drives the lead screw 2 to rotate, so that the tool holder 16 connected below the sliding fixing block 3 is aligned with the processing part (i.e., the outer peripheral wall of the ring-shaped or cylindrical structure 26) in the vertical direction. Then, the adjustable stroke cylinder 4 pushes the rotating column 13 down, causing the spherical cutter head 17 below the tool holder 16 to cut the surface of the part to be processed (i.e., the ring-shaped or cylindrical structure 26). The outer peripheral wall of the workpiece (i.e., the outer peripheral wall of the annular or cylindrical structure 26) can be gradually cut and deepened by the adjustable stroke cylinder 4 to form a single toothed groove 27 on the surface of the workpiece (i.e., the outer peripheral wall of the annular or cylindrical structure 26). Since the workpiece rotates around its own axis, the single toothed groove 27 is an annular groove set along the outer peripheral wall of the workpiece. Furthermore, during the process of the adjustable stroke cylinder 4 driving the rotating column 13 to press down, the spiral slide 14 provided on the outer peripheral wall of the rotating column 13 slides and engages with the protrusion on the inner side of the through hole 11, so that the rotating column 13 can rotate while descending. Thus, during the process of cutting and deepening the toothed groove 27, the spherical cutter head 17 can be evenly stressed, reducing the damage to the spherical cutter head 17.
[0021] Optionally, refer to Figure 1-6 The lower pressure block 5 has an annular protrusion 6 below it, and an annular groove 7 is provided on the inner side of the annular protrusion 6. The upper end of the rotating column 13 has an annular shoulder 12, which is slidably connected to the annular groove 7, so that the lower pressure block 5 and the rotating column 13 can rotate relative to each other around the central axis of the rotating column 13. With the configuration of this embodiment, the rotating column 13 and the lower pressure block 5 can be rotatably connected, so that the rotating column 13 can both transmit pressure downwards and rotate under the pressure of the lower pressure block 5.
[0022] Optionally, refer to Figure 1-6 The lower end face of the rotating column 13 is provided with a tool fixing groove 15, and a tool holder 16 is detachably connected inside the tool fixing groove 15. The spherical cutter head 17 is fixedly connected to the lower part of the tool holder 16. With the configuration of this embodiment, the tool can be easily replaced and installed.
[0023] Optionally, refer to Figure 1-2 The lead screw 2 comprises two screws arranged in parallel, and the sliding fixing block 3 is threadedly engaged with both lead screws 2. The two lead screws 2 are used to rotate in opposite directions, and under the driving action of the two lead screws 2, it can be ensured that the sliding fixing block 3 can only translate along the lead screw 2.
[0024] Optionally, refer to Figure 1-2 It also includes a transmission gear 18, a drive gear 19, and a translation motor 20. The transmission gear 18 is fixedly sleeved on the outer side of the lead screw 2, and the transmission gear 18 meshes with the drive gear 19. The translation motor 20 is connected to the drive gear 19 and is used to drive the drive gear 19 to rotate. With the configuration of this embodiment, the translation motor 30 can drive the two lead screws 2 to rotate in opposite directions through the drive gear 19 and the transmission gear 18, thereby driving the sliding fixed block 3 to translate.
[0025] Optionally, refer to Figure 1 A glass door 25 is rotatably connected to the front of the equipment housing 1, and a handle 10 is fixedly connected to the outside of the glass door 25. This configuration facilitates observation of the equipment's operating status and allows for easy handling of parts.
[0026] Optionally, refer to Figure 1-2 An operation screen 23 and operation buttons 24 are fixedly connected to the outside of the device housing 1. This configuration facilitates the setup of the device's operating program.
[0027] The implementation principle of one embodiment of the tooth-making structure in this application is as follows: During equipment operation, the adjustable stroke cylinder 4 is activated to drive the lowering block 5 to slowly press down. As the lowering block 5 slowly presses down, it passes through the spiral slide 14 on the outside of the fixed rotating column 13 below the limit block 12 and the protrusion fixed on the inside of the through hole 11. Then, it passes through the annular boss 6 and the annular groove 7, which will drive the limit block 12 to slowly descend and rotate. By operating the operation button 24 and programming the equipment, the ball cutter head 17 can be driven to rotate and turn, so that all four sides of the ball cutter head 17 participate in cutting, thereby improving the tool life, reducing enterprise production costs and improving equipment production efficiency.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
