Description

Technical Field

[0001] The present invention relates to the technical field of gear processing equipment, and particularly relates to a tooth profile positioning milling device for the production of reducer planetary gears. Background Art

[0002] The gear positioning milling equipment is a precision mechanical device designed specifically for the processing of reducer planetary gears. This device integrates advanced mechanical structures and intelligent control technologies to ensure the precise machining of the tooth profiles of planetary gears. It mainly consists of a base, a fixed workbench, an adjustable milling cutter assembly, and a numerical control system, etc. The base provides a stable support to ensure the stability during the machining process; the fixed workbench is used to clamp and position the planetary gear to be machined, ensuring that it does not move during the machining process. The adjustable milling cutter assembly is precisely adjusted according to the tooth profile requirements of the gear, and the milling cutter rotates at a high speed to precisely cut the gear surface to form a tooth profile that meets the design requirements. The numerical control system is the brain of the entire device, responsible for controlling key parameters such as the rotation speed, feed rate, and machining path of the milling cutter, realizing the automation and intelligence of the machining process. Through the precise control of the numerical control system, this device can efficiently and accurately complete the tooth profile machining of planetary gears, ensuring the meshing accuracy and transmission efficiency of the gears. In addition, this device also has the advantages of simple operation, high machining efficiency, and high machining accuracy, greatly improving the production efficiency and quality of reducer planetary gears. In short, the tooth profile positioning milling device for the production of reducer planetary gears is an important and indispensable equipment in the process of planetary gear machining, and its appearance has greatly promoted the development and progress of reducer manufacturing technology.

[0003] The existing gears have the following deficiencies: 1. In the prior art, during the process of loading the gear blank to be processed, its structural design is too cumbersome, which not only increases the operation difficulty of the operator but also prolongs the loading time, thus greatly reducing the convenience of gear processing.

[0004] 2. In the prior art, during the milling process of the gear blank, the generated metal chips often accumulate on the workbench surface. These chips will not only cause potential damage to the processing equipment but also may interfere with the processing process, affecting the machining accuracy and surface quality of the gear.

[0005] 3. In the prior art, during the milling process of the gear blank, the cutting fluid used often mixes with metal chips. If this cutting fluid mixed with chips cannot be collected and filtered in time, the recycling efficiency of the cutting fluid will be reduced.

[0006] For example, the "Tooth Profile Positioning Milling Device for the Production of Reducer Planetary Gears" disclosed in the Chinese invention patent (Application No.: 202410422540.2) has the following description in its specification: The present invention discloses a tooth profile positioning milling device for the production of reducer planetary gears, including a milling machine tool and a rotating table. The rotating table is fitted on one side of the milling machine tool. Four lifting rods are fitted and installed inside the rotating table, and telescopic arms are fixedly connected above the four lifting rods. The positioning insertion rod is inserted into the expansion table to expand the expansion table in all directions to fit the inner wall of the gear blank for positioning and fixing. When the hobbing cutter rotates to mill the gear blank, it drives the gear blank, the expansion table, the rotating base, and the rotating shaft to rotate synchronously. At the same time, the positioning insertion rod is arranged to be embedded in the expansion table, and the positioning disk is pressed against the upper part of the expansion table through the telescopic rod, thereby driving the positioning disk and the telescopic rod to rotate synchronously, so as to facilitate the cutting fluid to be sprayed from the nozzle to the milling area of the hobbing cutter and the gear blank for use, and further prevent the situation of equipment or personnel being injured when manually positioning and placing or operating improperly, and at the same time facilitate the recycling of the cutting fluid.

[0024] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation manners.

[0025] Among them, the accompanying drawings are only for illustrative purposes, showing only schematic diagrams, not physical diagrams, and should not be construed as a limitation to this patent; in order to better illustrate the embodiments of the present invention, some components in the accompanying drawings will be omitted, enlarged or reduced, and do not represent the dimensions of the actual product.

[0026] The present invention provides a technical solution. Referring to Figure 1 , Figure 2 , Figure 3, Figure 4 As shown in Figure 5 , a tooth profile positioning milling device for the production of a reducer planetary gear includes a base plate 1. On one side of the upper surface of the base plate 1, there is a rotary assembly 2. On the other side of the rotary assembly 2, there is a cleaning assembly 3. 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. Above the two positioning rods 201, there is a limit frame 202 fixedly connected. On one side of the inner wall of the limit frame 202, there is a toothed plate 208. The toothed plate 208 is meshed with a positioning gear 211. Above the positioning gear 211, there is an auxiliary disc 203 fixedly connected. On the upper surface of the auxiliary disc 203, there is a positioning frame 204. Inside the inner wall of the positioning frame 204, there is an electric telescopic rod 209 fixedly installed. On the outer wall of the electric telescopic rod 209, there is an auxiliary support plate 206. On the side of the positioning frame 204, there is a side window 205. The side window 205 is movably connected to the auxiliary support plate 206. One side of the auxiliary support plate 206 penetrates through the positioning frame 204 and is fixedly connected to a limit clamp 207. The limit clamp 207 is activated at the lowest position to clamp the gear blank to be processed. Then, the electric telescopic rod 209 is activated. Under the limit between the auxiliary support plate 206 and the side window 205 of the positioning frame 204, after the clamped gear blank is lifted to a suitable position, the auxiliary disc 203 moves. The positioning gear 211 located below the auxiliary disc 203 meshes with the toothed plate 208. As the disc moves, it drives the auxiliary disc 203 to rotate during displacement, so that it aligns with the expansion table 307. Then, the electric telescopic rod 209 contracts, and the gear blank is installed on the expansion table 307.

[0027] Through the displacement of the moving auxiliary disc 203 on the limit frame 202, the positioning gear 211 located below the auxiliary disc 203 meshes with the toothed plate 208 between the limit frames 202, so that while driving the gear blank to displace, it also rotates, thus being able to simplify its processing structure and improve the effect of gear processing while ensuring its processing quality.

[0028] Refer to Figure 3 , Figure 5 , Figure 8 and Figure 9As shown, the cleaning component 3 includes fixing plates 302 fixedly installed at both ends of the limiting frame 202. Opposite surfaces of the two fixing plates 302 are fixedly connected with inclined plates 304. A tooth window collecting plate 303 is fixedly connected between the two inclined plates 304. The surface of the tooth window collecting plate 303 is evenly distributed with a number of through holes 305. The upper surface of the auxiliary disk 203 is fixedly connected with a circular chute 301. The inner wall of the circular chute 301 is movably connected with an arc-shaped slide plate 310. The upper surface of the arc-shaped slide plate 310 is symmetrically and evenly distributed with two inclined frames 306 fixedly connected. One end of the two inclined frames 306 away from the arc-shaped slide plate 310 is fixedly installed with a scraping plate 308. The scraping plate 308 is movably connected with the tooth window collecting plate 303. A filtering component 5 is arranged below the tooth window collecting plate 303. The upper surface of the tooth window collecting plate 303 is fixedly connected with a rotating base 309. An expansion platform 307 is arranged above the rotating base 309. During the movement and rotation of the auxiliary disk 203, the circular chute 301 on the upper surface of the auxiliary disk 203 drives the arc-shaped slide plate 310 to move along. The two inclined frames 306 are pushed to move towards the expansion platform 307. The processed gear clamped in the expansion platform 307 is lifted and taken out by the inclined structure, disengaging from the expansion platform 307. At the same time, the scraping plate 308 connected to the two inclined frames 306 sweeps across the surface of the tooth window collecting plate 303. The metal debris after gear processing falls into the collection box 501 along the through holes 305 and the windows on the surface of the tooth window collecting plate 303, thereby cleaning the processed table surface.

[0029] The moving auxiliary disk 203 drives the two inclined frames 306 to approach the expansion platform 307, lifting the processed gear in the expansion platform 307 with an inclined structure to disengage it from the expansion platform 307, enabling quick part taking, increasing the efficiency of gear processing. At the same time, the scraping plate 308 connected to the other ends of the two inclined frames 306 cleans the metal debris on the surface of the tooth window collecting plate 303, facilitating the collection of metal debris and preventing it from affecting the gear processing process, thus enabling switching between the part taking structure and the cleaning structure and improving the convenience of gear processing.

[0030] Refer to 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 tooth window collection plate 303, the inner wall of the collection box 501 is movably connected with an extrusion mesh plate 504, one side of the extrusion mesh plate 504 is fixedly connected with a support cross frame 506, one end of the support cross frame 506 passes through the collection box 501 and is fixedly connected with a slide rod 509, the upper part of the slide rod 509 is movably installed just below the positioning gear 211, the outer wall of the slide rod 509 is movably connected with a support slide groove 505, the support slide groove 505 is fixedly connected to a fixed frame 210 at one end away from the collection box 501, an auxiliary telescopic rod 507 is fixedly connected below the support cross frame 506, the other end of the auxiliary telescopic rod 507 is fixedly installed on the side of the collection box 501, and the inner wall of the collection box 501 is fixedly connected with a pump body 503 A conduit 502 is fixedly installed at the output end of the pump body 503, and the other end of the conduit 502 passes through the collection box 501 and is fixedly connected to a diversion spray disc 508. During the movement of the auxiliary disc 203, the sliding rod 509 at the bottom drives the supporting cross frame 506 to move, driving the extrusion mesh plate 504 to move in the collection box 501, pushing the cutting fluid mixed with metal debris to move, and the metal debris is pushed to one side of the collection box 501, and the cutting fluid passes through the moving extrusion mesh plate 504 to filter the cutting fluid in real time. While filtering the cutting fluid, the moving extrusion mesh plate 504 passes over the lower surface of the tooth window collection plate 303, thereby cleaning the through hole 305 of the tooth window collection plate 303 to prevent it from being blocked and affecting the introduction of the cutting fluid.

[0031] By moving the auxiliary disk 203, the extrusion mesh plate 504 is driven to move in the collection box 501, and the metal debris in the cutting fluid is pushed by moving and extruding. The cutting fluid passes through the extrusion mesh plate 504 and flows to one side of the collection box 501, and the metal debris is pushed to the other side of the collection box 501, so as to filter the cutting fluid mixed with metal debris in real time, thereby increasing the efficiency of cutting fluid recycling. At the same time, the extrusion mesh plate 504 moves on the lower surface of the tooth window collection plate 303 during the moving process, sweeping across the through hole 305 for cleaning, thereby performing a preliminary cleaning of the plate body where the cutting fluid is collected, preventing metal debris from clogging the collection holes and affecting the collection of the cutting fluid, so that it can be flexibly switched between the real-time filtering structure and the hole cleaning structure, thereby ensuring the efficiency of cutting fluid recycling.

A processing tool 10 is movably connected between the two side plates 9, and a transmission gear 15 is fixedly connected to one end of the shaft of the processing tool 10. The transmission gear 15 is meshed and connected to an auxiliary gear 14, and a driving motor 13 is fixedly connected to one side of the auxiliary gear 14. Two slides 7 are fixedly connected to the side of the support frame 8 in a symmetrical and evenly distributed manner. The inner wall of the slide 7 is movably connected to a slide rail 6, and the rear ends of the two slide rails 6 are fixedly installed with a shell 4. The middle of the rear end of the support frame 8 is fixedly connected There is a threaded sleeve 16, and a lead screw 11 is movably connected to the inner wall of the threaded sleeve 16. A servo motor 12 is fixedly connected below the lead screw 11. The servo motor 12 drives the lead screw 11 to rotate forward and reverse, and then the threaded sleeve 16 threadedly connected to the lead screw 11 moves up and down, driving the processing tool 10 located in the support frame 8 to perform precise displacement. During the displacement process, the drive motor 13 is started to drive the auxiliary gear 14 to rotate, and then the transmission gear 15 meshing with it follows the rotation to provide power for the processing tool 10, so as to perform cutting operations on the gear blank.

[0033] The working principle of the present invention is as follows: the staff places the gear blank to be processed on the table, then starts the electric telescopic rod 209 to shrink, drives the auxiliary frame 206 to move downward, moves the limiting clamp 207 located on one side of the auxiliary frame 206 to the periphery of the gear blank under the limit of the side window 205 in the positioning frame 204, starts the limiting clamp 207 to clamp the gear blank to be processed, and after completion, starts the electric telescopic rod 209 to extend, so as to lift the clamped gear blank to a height higher than the height of the expansion table 307; Retrieving materials: Start the electric telescopic rod 209 to drive the supporting cross frame 506 to move, and with the cooperation of the sliding rod 509, drive the auxiliary gear 14 to move between the limiting frames 202. Since the tooth plate 208 installed on the inner wall of the limiting frame 202 is meshed with the auxiliary gear 14, the auxiliary gear 14 drives the auxiliary disk 203 to rotate during the displacement process, and then the circular slide 301 above the auxiliary disk 203 rotates in coordination, and the arc slide plate 310 in the circular slide 301 is driven to push the two inclined frames 306 to move toward the expansion platform 307, and the gear clamped in the expansion platform 307 is lifted by the inclined plate body to make it separate from the expansion platform 307; Cleaning: When the two inclined frames 306 move toward the expansion table 307, they drive the scraper 308 to move on the surface of the tooth window collecting plate 303, pushing the metal debris in the gear processing process to move and pass over the surface of the tooth window collecting plate 303. The metal debris after gear processing falls into the collection box 501 along the through hole 305 and the window on the surface of the tooth window collecting plate 303, so as to clean the table after processing; Filtration: Driven by the contraction of the electric telescopic rod 209, the support cross frame 506 pushes the extrusion mesh plate 504 in the collection box 501 to move, and pushes the cutting fluid mixed with metal chips to move, and the metal chips are pushed to one side of the collection box 501, and the cutting fluid passes through the moving extrusion mesh plate 504 to filter the cutting fluid in real time. While filtering the cutting fluid, the moving extrusion mesh plate 504 passes over the lower surface of the tooth window collection plate 303; Installation: The auxiliary disk 203 drives the gear embryo to move. Under the cooperation of the tooth plate 208 and the auxiliary gear 14, the gear embryo rotates with the center of the auxiliary disk 203 while being displaced. The displaced and rotated gear embryo is aligned with the central axis of the expansion ring. At this time, the electric telescopic rod 209 is started to contract, driving the gear embryo in the limit clamp 207 to contact the expansion platform 307 to complete the positioning of the gear before processing; Processing: Start the servo motor 12 to drive the lead screw 11 to rotate forward and reverse, and then the threaded sleeve 16 threadedly connected to the lead screw 11 moves up and down, driving the processing tool 10 located in the support frame 8 to move accurately. During the displacement process, start the drive motor 13 to drive the auxiliary gear 14 to rotate, and then the transmission gear 15 meshing with it rotates to provide power for the processing tool 10, so as to cut the gear embryo. During the cutting process of the gear embryo, start the rotating base 309 to drive the gear embryo located in the expansion table 307 to rotate; Flushing: Start the pump body 503 located on one side of the collection box 501 to extract the filtered cutting fluid, guide it into the diversion spray plate 508 along the conduit 502, and guide it to the gear blank being processed, so as to flush the metal debris remaining on the surface of the gear blank and make it fall on the surface of the tooth window collection plate 303. With the obstruction of the inclined plates 304 on both sides, the cutting fluid mixed with metal debris falls into the collection box 501 along the through hole 305 for collection.
