Description

Technical Field

[0001] This invention relates to the field of gear processing equipment technology, and specifically to a tooth profile positioning milling device for producing planetary gears for speed reducers. Background Technology

[0002] The gear positioning milling machine is a precision mechanical device specifically designed for machining planetary gears in speed reducers. This device integrates advanced mechanical structure and intelligent control technology to ensure precise machining of the planetary gear teeth. It mainly consists of a base, a fixed worktable, an adjustable milling cutter assembly, and a CNC system. The base provides stable support, ensuring stability during machining; the fixed worktable clamps and positions the planetary gear to be machined, ensuring it does not move during machining. The adjustable milling cutter assembly is precisely adjusted according to the gear tooth profile requirements, using a high-speed rotating milling cutter to precisely cut the gear surface, forming a tooth profile that meets design requirements. The CNC system is the brain of the entire device, responsible for controlling key parameters such as the milling cutter's rotation speed, feed rate, and machining path, achieving automation and intelligence in the machining process. Through the precise control of the CNC system, this device can efficiently and accurately complete the machining of planetary gear teeth, ensuring gear meshing accuracy and transmission efficiency. Furthermore, this device has advantages such as simple operation, high machining efficiency, and high machining accuracy, greatly improving the production efficiency and quality of planetary gears for speed reducers. In summary, the tooth profile positioning milling device for planetary gear production is an indispensable and important piece of equipment in the planetary gear processing, and its emergence has greatly promoted the development and progress of reducer manufacturing technology.

[0003] The existing gears have the following shortcomings:

[0004] 1. In the existing technology, the structural design of the gear blank to be processed is too complicated. This not only increases the difficulty of operation for operators, but also prolongs the feeding time, thereby greatly reducing the convenience of gear processing.

[0005] 2. In the prior art, during the milling process of gear blanks, the metal chips generated often accumulate on the worktable. These chips not only cause potential damage to the processing equipment, but may also interfere with the processing, affecting the machining accuracy and surface quality of the gears.

[0006] 3. In the prior art, the cutting fluid used in the milling process of gear blanks is often mixed with metal chips. If the cutting fluid mixed with chips cannot be collected and filtered in time, the efficiency of cutting fluid recycling and reuse will be reduced.

[0007] For example, the Chinese invention patent (application number: 202410422540.2) discloses a "tooth profile positioning milling device for producing planetary gears of a speed reducer," the description of which states: This invention discloses a tooth profile positioning milling device for producing planetary gears of a speed reducer, including a milling machine tool and a rotary table. The rotary table is fitted onto one side of the milling machine tool, and four lifting rods are fitted onto the inner side of the rotary table. A telescopic arm is fixedly connected above each of the four lifting rods; a positioning rod is inserted into an expansion table to cause the expansion table to expand outwards to fit the inner surface of the gear blank. The hobbing cutter is positioned and fixed on the wall. When it rotates to mill the gear blank, it drives the gear blank, expansion table, rotating base, and rotating shaft to rotate synchronously. Simultaneously, the positioning rod is embedded in the expansion table, and the positioning disc is pressed against the top of the expansion table via a telescopic rod. This causes the positioning disc and telescopic rod to rotate synchronously, allowing the cutting fluid to be sprayed from the nozzle onto the milling area of ​​the hobbing cutter and gear blank. This prevents injury to equipment or personnel due to manual positioning or improper operation, and also facilitates the recycling of the cutting fluid. The aforementioned patent can corroborate the deficiencies of the existing technology. Summary of the Invention

[0008] The purpose of this invention is to provide a tooth profile positioning milling device for the production of planetary gears for speed reducers.

[0009] To achieve this objective, the present invention adopts the following technical solution:

[0010] A tooth profile positioning milling device for producing planetary gears of a speed reducer is provided, including a base plate, a rotary assembly on one side of the upper surface of the base plate, and a cleaning assembly on the other side of the rotary assembly;

[0011] The rotary assembly includes two positioning rods that are symmetrically and evenly distributed and fixedly installed on the surface of the base plate. A limit frame is fixedly connected above the two positioning rods. A toothed plate is fixedly connected to one side of the inner wall of the limit frame. A positioning gear is meshed with the toothed plate. An auxiliary disk is fixedly connected above the positioning gear. A positioning frame is provided on the upper surface of the auxiliary disk. An electric telescopic rod is fixedly installed on the inner wall of the positioning frame. An auxiliary frame plate is provided on the outer wall of the electric telescopic rod.

[0012] Furthermore, the positioning frame is provided with a side window on its side, the side window is movably connected to the auxiliary frame plate, and a limit clamp is fixedly connected to one side of the auxiliary frame plate through the positioning frame.

[0013] Furthermore, the cleaning assembly includes two fixed plates fixedly installed on one side of the limiting frame. An inclined plate is fixedly connected to the opposite surfaces of the two fixed plates. A toothed window collecting plate is fixedly connected between the two inclined plates. The surface of the toothed window collecting plate has a plurality of through holes evenly distributed. A circular groove is fixedly connected to the upper surface of the auxiliary disc. An arc-shaped sliding plate is movably connected to the inner wall of the circular groove. Two inclined frames are fixedly connected to the upper surface of the arc-shaped sliding plate in a symmetrical and even distribution. A scraper is fixedly installed at the end of each of the two inclined frames away from the arc-shaped sliding plate. The scraper is movably connected to the toothed window collecting plate. A filter assembly is provided below the toothed window collecting plate.

[0014] Furthermore, a rotating base is fixedly connected to the upper surface of the toothed window collecting plate, and an expansion platform is provided above the rotating base.

[0015] Furthermore, the filter assembly includes a collection box fixedly installed below the toothed window collection plate. An extrusion mesh plate is movably connected to the inner wall of the collection box. A support crossbar is fixedly connected to one side of the extrusion mesh plate. A slide rod is fixedly connected to one end of the support crossbar through the collection box. The slide rod is movably installed directly below the positioning gear. A support groove is movably connected to the outer wall of the slide rod. A fixing frame is fixedly connected to the end of the support groove away from the collection box.

[0016] Furthermore, an auxiliary telescopic rod is fixedly connected below the supporting crossbeam, and the other end of the auxiliary telescopic rod is fixedly installed on the side of the collection box.

[0017] Furthermore, a pump body is fixedly connected to the inner wall of the collection box, a conduit is fixedly installed at the output end of the pump body, and the other end of the conduit passes through the collection box and is fixedly connected to a diversion spray plate.

[0018] Furthermore, a support frame is fixedly connected below the flow-dividing spray disc, and two side plates are fixedly connected symmetrically and evenly below the support frame. A processing tool is movably connected between the two side plates. A transmission gear is fixedly connected to one end of the shaft of the processing tool, and an auxiliary gear is meshed with the transmission gear. A drive motor is fixedly connected to one side of the auxiliary gear.

[0019] Furthermore, the support frame has two slides that are symmetrically and evenly distributed and fixedly connected on its side. The inner wall of each slide is movably connected to a slide rail, and the rear ends of the two slide rails are fixedly installed with a housing.

[0020] Furthermore, a threaded sleeve is fixedly connected to the middle of the rear end of the support frame, a lead screw is movably connected to the inner wall of the threaded sleeve, and a servo motor is fixedly connected below the lead screw.

[0021] The beneficial effects of this invention are:

[0022] 1. This invention, through its design, uses a movable auxiliary disk to move above a limiting frame, while a positioning gear located below the auxiliary disk meshes with a toothed plate between the limiting frame, causing the gear blank to move and rotate simultaneously. This simplifies the processing structure and improves the gear processing effect while ensuring the processing quality.

[0023] 2. This invention, through its design, uses a movable auxiliary disc to move two inclined frames closer to the expansion table. The inclined structure lifts the gear that has been processed on the expansion table, allowing it to detach from the expansion table. This enables rapid part removal and increases the efficiency of gear processing. At the same time, scrapers connected to the other end of the two inclined frames clean up metal debris on the surface of the gear window collection plate, facilitating the collection of metal debris and preventing it from affecting the gear processing. This allows the invention to switch between the material handling structure and the cleaning structure, improving the convenience of gear processing.

[0024] 3. This invention, through its design, uses the movement of an auxiliary disc to move a squeezing screen within a collection box. This moving squeezing action pushes metal debris from the cutting fluid, causing the cutting fluid to flow through the squeezing screen to one side of the collection box, while the metal debris is pushed to the other side. This real-time filtration of the cutting fluid mixed with metal debris increases the efficiency of cutting fluid recycling. Simultaneously, the moving squeezing screen moves across the lower surface of the toothed window collection plate, cleaning the through-holes. This initial cleaning of the cutting fluid collection plate prevents metal debris from clogging the collection holes and affecting cutting fluid collection. This allows for flexible switching between real-time filtration and hole cleaning structures, ensuring efficient cutting fluid recycling. Attached Figure Description

[0038] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0040] This invention provides a technical solution, referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a tooth profile positioning milling device for producing planetary gears of a speed reducer includes a base plate 1. A rotary assembly 2 is provided on one side of the upper surface of the base plate 1, and a cleaning assembly 3 is provided on the other side of the rotary assembly 2. The rotary assembly 2 includes two positioning rods 201 that are symmetrically and evenly distributed and fixedly installed on the surface of the base plate 1. A limit frame 202 is fixedly connected above the two positioning rods 201. A toothed plate 208 is fixedly connected to one side of the inner wall of the limit frame 202. A positioning gear 211 is meshed with the toothed plate 208. An auxiliary disk 203 is fixedly connected above the positioning gear 211. A positioning frame 204 is provided on the upper surface of the auxiliary disk 203. An electric telescopic rod 209 is fixedly installed on the inner wall of the positioning frame 204. An auxiliary frame plate 206 is provided on the outer wall of the electric telescopic rod 209. A side window is provided on the side of the positioning frame 204. 205. The side window 205 is movably connected to the auxiliary frame plate 206. A limiting clamp 207 is fixedly connected to one side of the auxiliary frame plate 206 through the positioning frame 204. When the limiting clamp 207 is activated at its lowest position, it clamps the gear blank to be processed. Then, the electric telescopic rod 209 is activated. Under the limitation between the auxiliary frame plate 206 and the side window 205 of the positioning frame 204, the clamped gear blank is lifted to a suitable position. Then, the auxiliary disk 203 moves, and the positioning gear 211 located below the auxiliary disk 203 meshes with the gear plate 208. As the disk moves, it drives the auxiliary disk 203 to rotate in displacement, aligning it with the expansion table 307. Then, the electric telescopic rod 209 retracts, and the gear blank is installed on the expansion table 307.

[0041] The auxiliary disk 203 moves above the limiting frame 202, and the positioning gear 211 located below the auxiliary disk 203 meshes with the toothed plate 208 between the limiting frame 202, causing the gear blank to move and rotate at the same time. This simplifies the processing structure and improves the effect of gear processing while ensuring the processing quality.

[0042] Reference Figure 3 , Figure 5 , Figure 8 and Figure 9As shown, the cleaning component 3 includes fixed plates 302 fixedly installed at both ends of the limiting frame 202. Inclined plates 304 are fixedly connected to the opposite surfaces of the two fixed plates 302. A toothed window collecting plate 303 is fixedly connected between the two inclined plates 304. The surface of the toothed window collecting plate 303 has a plurality of through holes 305 evenly distributed. A circular groove 301 is fixedly connected to the upper surface of the auxiliary disk 203. An arc-shaped sliding plate 310 is movably connected to the inner wall of the circular groove 301. Two inclined frames 306 are symmetrically and evenly fixedly connected to the upper surface of the arc-shaped sliding plate 310. A scraper 308 is fixedly installed at the end of the two inclined frames 306 away from the arc-shaped sliding plate 310. The scraper 308 is movably connected to the toothed window collecting plate 303. A filter component 5 is provided below the toothed window collecting plate 303. A rotating base 309 is fixedly connected to the upper surface of the plate 303. An expansion platform 307 is provided above the rotating base 309. During the movement and rotation of the auxiliary disk 203, the circular slide groove 301 on the upper surface of the auxiliary disk 203 drives the arc slide plate 310 to move along with it, pushing the two inclined frames 306 to move towards the expansion platform 307. The gear that has been processed and clamped in the expansion platform 307 is lifted and taken out by the inclined structure and separated from the expansion platform 307. At the same time, the scraper 308 connected to the two inclined frames 306 sweeps across the surface of the toothed window collecting plate 303. The metal chips after the gear processing fall into the collecting box 501 through the through hole 305 and the window on the surface of the toothed window collecting plate 303, thereby cleaning the processed table surface.

[0043] The moving auxiliary disk 203 drives the two inclined frames 306 to approach the expansion table 307, lifting the gear that has been processed in the expansion table 307 with an inclined structure, so that it can be removed from the expansion table 307. This enables quick part removal and increases the efficiency of gear processing. At the same time, the scraper 308 connected to the other end of the two inclined frames 306 cleans the metal debris on the surface of the gear window collection plate 303, so as to facilitate the collection of metal debris and prevent it from affecting the gear processing. This allows the machine to switch between the material handling structure and the cleaning structure, improving the convenience of gear processing.

[0044] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 8 and Figure 10As shown, the filter assembly 5 includes a collection box 501 fixedly installed below the toothed window collection plate 303. An extrusion mesh plate 504 is movably connected to the inner wall of the collection box 501. A support crossbar 506 is fixedly connected to one side of the extrusion mesh plate 504. One end of the support crossbar 506 passes through the collection box 501 and is fixedly connected to a slide rod 509. The slide rod 509 is movably installed above and directly below the positioning gear 211. A support groove 505 is movably connected to the outer wall of the slide rod 509. A fixing frame 210 is fixedly connected to the end of the support groove 505 away from the collection box 501. An auxiliary telescopic rod 507 is fixedly connected below the support crossbar 506. The other end of the auxiliary telescopic rod 507 is fixedly installed on the side of the collection box 501. A pump body 503 is fixedly connected to the inner wall of the collection box 501. A conduit 502 is fixedly installed at the output end of the pump body 503. The other end of the conduit 502 passes through the collection box 501 and is fixedly connected to a diverter spray disc 508. During the movement of its auxiliary disc 203, the slide bar 509 located below drives the support crossbar 506 to move accordingly, causing the extrusion screen 504 to move within the collection box 501, pushing the cutting fluid mixed with metal chips to move. The metal chips are pushed to one side of the collection box 501, and the cutting fluid passes through the moving extrusion screen 504 to filter the cutting fluid in real time. At the same time as filtering the cutting fluid, the moving extrusion screen 504 sweeps across the lower surface of the toothed window collection plate 303 to clean the through holes 305 of the toothed window collection plate 303, preventing them from becoming blocked and affecting the introduction of cutting fluid.

[0045] The movement of the auxiliary disc 203 drives the extrusion screen 504 to move within the collection tank 501. Through this moving extrusion mechanism, metal debris in the cutting fluid is pushed forward, while the cutting fluid flows through the extrusion screen 504 to one side of the collection tank 501. The metal debris is pushed to the other side, thus filtering the cutting fluid mixed with metal debris in real time and increasing the efficiency of cutting fluid recycling. Simultaneously, the movement of the extrusion screen 504 over the lower surface of the toothed collection plate 303 cleans the through-holes 305, providing initial cleaning of the cutting fluid collection plate and preventing metal debris from clogging the collection holes and affecting cutting fluid collection. This allows for flexible switching between real-time filtration and hole cleaning structures, ensuring efficient cutting fluid recycling.

[0046] Reference Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, a support frame 8 is fixedly connected below the flow-diverting spray disc 508. Two side plates 9 are symmetrically and evenly distributed and fixedly connected below the support frame 8. A machining tool 10 is movably connected between the two side plates 9. A transmission gear 15 is fixedly connected to one end of the shaft of the machining tool 10. An auxiliary gear 14 is meshed with the transmission gear 15. A drive motor 13 is fixedly connected to one side of the auxiliary gear 14. Two slides 7 are symmetrically and evenly distributed and fixedly connected to the side of the support frame 8. A slide rail 6 is movably connected to the inner wall of the slide 7. A housing 4 is fixedly installed at the rear end of the two slide rails 6. A housing 4 is fixedly connected to the middle of the rear end of the support frame 8. A threaded sleeve 16 is provided, and a lead screw 11 is movably connected to the inner wall of the threaded sleeve 16. A servo motor 12 is fixedly connected to the lower part of the lead screw 11. The servo motor 12 drives the lead screw 11 to rotate in both directions, and the threaded sleeve 16, which is threaded to the lead screw 11, moves up and down, driving the machining tool 10 located in the support frame 8 to move precisely. During the movement, the drive motor 13 is started, driving the auxiliary gear 14 to rotate, and the transmission gear 15, which is meshed with it, rotates accordingly to provide power to the machining tool 10, thereby performing a cutting operation on the gear blank.

[0047] The working principle of this invention is as follows: The operator places the gear blank to be processed on the table, and then starts the electric telescopic rod 209 to retract, which drives the auxiliary frame plate 206 to move downward. Under the limitation of the side window 205 in the positioning frame 204, the limiting clamp 207 located on one side of the auxiliary frame plate 206 is moved to the vicinity of the gear blank. The limiting clamp 207 is activated to clamp the gear blank to be processed. After completion, the electric telescopic rod 209 is activated to extend, which raises the clamped gear blank to a height higher than the expansion table 307.

[0048] Material handling: Start the electric telescopic rod 209 to drive the support crossbeam 506 to move. With the cooperation of the slide rod 509, the auxiliary gear 14 is driven to move between the limit frame 202. Since the toothed plate 208 installed on the inner wall of the limit frame 202 meshes with the auxiliary gear 14, the auxiliary gear 14 drives the auxiliary disk 203 to rotate during the displacement process. Then the circular slide groove 301 above the auxiliary disk 203 rotates in coordination, and the arc slide plate 310 in the circular slide groove 301 is driven to push the two inclined frames 306 to move towards the expansion platform 307. The inclined plate lifts the gear clamped in the expansion platform 307 and makes it disengage from the expansion platform 307.

[0049] Cleaning: As the two inclined frames 306 move toward the expansion table 307, they drive the scraper 308 to move on the surface of the gear window collection plate 303, pushing the metal chips from the gear processing process to move across the surface of the gear window collection plate 303. The metal chips from the gear processing then fall into the collection box 501 through the through holes 305 and windows on the surface of the gear window collection plate 303, thus cleaning the processed table surface.

[0050] Filtration: Driven by the retraction of the electric telescopic rod 209, the support crossbar 506 pushes the extrusion screen 504 in the collection box 501 to move, pushing the cutting fluid mixed with metal chips to move. The metal chips are pushed to one side of the collection box 501, and the cutting fluid passes through the moving extrusion screen 504 to filter the cutting fluid in real time. At the same time as filtering the cutting fluid, the moving extrusion screen 504 sweeps over the lower surface of the toothed window collection plate 303.

[0051] Installation: The auxiliary disk 203 drives the gear blank to move. With the cooperation of the gear plate 208 and the auxiliary gear 14, the gear blank rotates around the center of the auxiliary disk 203 while it is displaced. After displacement and rotation, the gear blank is aligned with the central axis of the expansion ring. At this time, the electric telescopic rod 209 is activated to retract, which drives the gear blank in the limit clamp 207 to contact the expansion table 307 to complete the positioning before gear processing.

[0052] Machining: The servo motor 12 is started to drive the lead screw 11 to rotate in both directions. Then the threaded sleeve 16, which is threaded to the lead screw 11, moves up and down, driving the machining tool 10 located in the support frame 8 to move precisely. During the movement, the drive motor 13 is started to drive the auxiliary gear 14 to rotate. Then the transmission gear 15, which is meshed with it, rotates to provide power to the machining tool 10, thereby cutting the gear blank. During the cutting of the gear blank, the rotating base 309 is started to drive the gear blank located in the expansion table 307 to rotate.

[0053] Rinsing: The pump body 503 located on one side of the collection box 501 is started to draw the filtered cutting fluid and guide it into the diverting spray plate 508 through the conduit 502, so that it is directed into the gear blank being processed, and the metal chips remaining on the surface of the gear blank are rinsed off and fall onto the surface of the gear window collection plate 303. With the obstruction of the inclined plates 304 on both sides, the cutting fluid mixed with metal chips falls into the collection box 501 through the through hole 305 for collection.
