Description

Technical Field

[0001] This invention relates to the field of internal gear machining technology, specifically to a tooling for machining internal gear rings. Background Technology

[0002] Internal gear ring shaping is a key process in the field of mechanical transmission. Its machining accuracy directly affects the transmission smoothness and load-bearing capacity when the internal gear ring meshes with the gear. However, when performing internal gear shaping on thin-walled or relatively thin-sized ring workpieces, existing gear shaping fixtures often cause deformation or positional displacement of the inner ring due to insufficient workpiece rigidity and difficulty in clamping and positioning. At the same time, if the large amount of chips and high-temperature coolant generated during the gear shaping process cannot be separated and directionally discharged in time, it will not only pollute the machining environment and reduce tool life, but also interfere with the continuity of automated cycle operations. In addition, traditional fixed nozzles are difficult to keep aligned with the cutting area when the workpiece is rotated and clamped, which can easily cause uneven cooling and lubrication, thus affecting the tooth surface quality and machining efficiency.

[0003] Patent CN213195974U discloses a tooling for machining internal gear rings, including a base with multiple annularly spaced grooves on its top surface. A fixing ring is fixedly connected to the top surface of the base by rivets, and multiple annularly spaced mounting seats are fixedly installed on the outer circumference of the fixing ring. Each mounting seat is fixedly connected to a cylinder by bolts. The tooling for machining internal gear rings utilizes the fixing ring, cylinders, and multiple clamping mechanisms. The piston rods of the multiple cylinders move synchronously, driving the fixing seats to move. Simultaneously, multiple clamping blocks clamp the outer wall of the internal gear ring and fix it. Additionally, rollers, a motor, and a conveyor belt are included. Under the transmission action of the conveyor belt, the clamping blocks and the internal gear ring can be finely adjusted in the vertical direction, facilitating changes in the machining position of the internal gear ring and making machining easier. However, this patent still has the problem that the machining of the inner gear ring of a thin-walled workpiece requires manual adjustment.

[0008] According to the above technical solution, the solid-liquid separation mechanism includes a sliding rod, a lifting ring is fixedly connected to the bottom end of the sliding rod, a filter hood is fixedly connected to the inner side of the lifting ring, a sliding block is fixedly connected to the upper surface of the lifting ring, multiple torsion grooves are opened on the inner wall of the inclined chute turntable, and a hydraulic rod is rotatably connected below the axis of the filter hood.

[0009] According to the above technical solution, a collection box is fixedly connected to the bottom surface of the platform, a discharge port is opened on the side of the collection box, an isolation cover ring is fixedly connected to the middle of the inner side of the collection box, and an infusion port is opened on the bottom surface of the collection box.

[0010] According to the above technical solution, the torsion chute is slidably connected to the chute block, the hydraulic rod is fixedly connected to the collection box, and the isolation cover ring is slidably connected to the lifting ring.

[0011] According to the above technical solution, the spray linkage mechanism includes a connecting rod plate, a through-box rod is fixedly connected to the end of the connecting rod plate, a linkage rod is fixedly connected to the bottom end of the through-box rod, an elastic rod is slidably connected to the end of the linkage rod away from the through-box rod, a sleeve block is fixedly connected to the top end of the elastic rod, an infusion seat is slidably connected to the inner side of the sleeve block, a threaded strip is fixedly connected to the outer side of the infusion seat, and a spray nozzle assembly is fixedly connected to the top end of the infusion seat.

[0012] According to the above technical solution, the connecting rod plate is fixedly connected to the extension rod of the hydraulic rod, a thrust spring is provided on the outer side of the elastic rod, and the two ends of the thrust spring are fixedly connected to the sleeve block and the linkage rod respectively. The threaded strip is threadedly connected to the sleeve block, and the infusion seat is rotatably connected to the platform.

[0013] The present invention, by adopting the above technical solution, can bring the following beneficial effects: This tooling for internal gear ring shaping utilizes a machining tooling mechanism that employs rolling support from the side wheels to reduce friction on the workpiece's bottom surface. Simultaneously, it elevates the workpiece, disengaging it from the bottom contact surface. This avoids deformation and positioning errors in thin-sized annular workpieces caused by uneven force on the bottom or adjustments to the inner ring clamping. Frequent adjustments to the workpiece's posture are unnecessary. Furthermore, the compression deformation of the cavity groove adapts to the outer ring contour with varying curvatures, increasing the contact area and friction between the contact block and the workpiece's outer ring. This achieves elastic self-adhesive clamping, preventing rigid clamping that could damage the workpiece surface. Combined with the engaging hinge blocks on both sides of the fixture end, this increases the contact points for workpiece fixation. The multi-point joint constraint significantly enhances the workpiece's resistance to torsion and offset during the gear shaping process, ensuring machining accuracy and stability.

[0014] The tooling used for machining internal gear rings incorporates a solid-liquid separation mechanism. A filter hood is lifted and pressed against the inner wall of the turntable, preparing for the subsequent collection of debris and coolant. During the workpiece rotation process, the filter hood and hydraulic rod rotate synchronously, preventing seal failure or structural interference caused by relative motion and ensuring continuous dynamic filtration. Simultaneously, solid-liquid separation is achieved through the gaps in the filter hood, preventing debris from entering the coolant circulation system and reducing the burden on subsequent filtration. Furthermore, gravity and the inclined plane cause debris to accumulate above the filter hood, while coolant gathers inside the isolation ring, enabling the classified collection and rapid cleaning of materials after machining, improving maintenance convenience.

[0015] The tooling used for internal gear ring shaping incorporates a liquid spraying linkage mechanism. Utilizing the extension of a hydraulic rod during clamping as a drive source, and through sequential transmission of connecting rods and springs, the nozzle assembly automatically deflects without requiring additional power or control components, reducing costs and failure rates. Simultaneously, a threaded guide sleeve block slides, allowing the liquid delivery seat to rotate precisely, ensuring the nozzle assembly end is stably aligned with the meshing area between the tool and workpiece. This provides targeted cooling and lubrication, effectively reducing cutting heat in the shaping area. The built-in pump delivers liquid from the isolation ring through a pipeline to the bottom of the liquid delivery seat, and then from the seat to the nozzle assembly end, achieving coolant recycling. The clean coolant separated and collected in the isolation ring after machining is pumped back to the nozzle assembly, forming a closed-loop cooling circuit. This significantly saves cutting fluid consumption and ensures the continuity and stability of the spraying process. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-7 An embodiment of the present invention is as follows: a tooling for machining internal gear rings includes a machining stand 1, a table 2, a guard 3, and a side box 4. The top of the table 2 is provided with a machining tooling mechanism 5 for clamping the workpiece for machining the gear ring. Below the processing tooling mechanism 5 is a solid-liquid separation mechanism 6 for collecting waste residue and coolant; The side of the machining tooling mechanism 5 is provided with a liquid spraying linkage mechanism 7 that changes the position of the nozzle according to the machining steps; The machining fixture mechanism 5 includes a sloping turntable 501. The upper surface of the sloping turntable 501 has multiple sliding rod grooves 505. A guide rod 502 is fixedly connected to the inner wall of each sliding rod groove 505. A vertical sliding rod 503 is slidably connected to the outer surface of each guide rod 502. A rocker turntable 504 is arranged above the sloping turntable 501. The upper surface of the rocker turntable 504 has multiple rocker rod grooves 506. Eight sets of tracks 507 are arranged on the upper surface of the rocker turntable 504. A slider 508 is slidably connected above each set of rocker turntables 504. A clamping end 509 is fixedly connected to the top of the slider 508. A rubber pad 510 is arranged inside the clamping end 509. Two cavity grooves 511 are opened inside the rubber pad 510. A contact block 512 is fixedly connected to the side of the rubber pad 510.

[0020] The machining tooling mechanism 5 also includes a engagement hinge block 513, which is hinged to both sides of each fixture end 509. A guide ring push plate 514 is fixedly connected to the side of the slider 508. A side wheel 515 is provided between the guide ring push plate 514 and the slider 508. A worm gear tooth groove 517 is provided on the outer wall of the inclined groove turntable 501. A worm 516 is meshed with the side of the worm gear tooth groove 517.

[0021] The inclined chute turntable 501 is rotatably connected to the platform 2, the rocker arm groove 506 is slidably connected to the vertical slide rod 503, the rocker arm turntable 504 is rotatably connected to the inclined chute turntable 501, the rubber pad block 510 is H-shaped, the contact block 512 is slidably connected to the clamp end 509, the side wheel 515 is rotatably connected to the guide ring push plate 514, and the worm gear 516 is installed on the bottom surface of the platform 2. When the rocker arm turntable 504 and the inclined chute turntable 501 rotate relative to each other, the rocker arm turntable 504 pushes the vertical slide rod 503 along the guide rod 502 through the rocker arm groove 506, causing the vertical slide rod 503 to slide along the slide rod groove 505. At this time, the vertical slide bar 503 drives the connected slider 508 to slide along the track 507 and drive the clamping end 509 to move closer to the outer side of the annular workpiece. The movement of the clamping end 509 simultaneously drives the guide ring push plate 514 to move together. The inclined surface of the guide ring push plate 514 lifts the annular workpiece from the bottom, so that the bottom surface of the ring slides along the guide ring push plate 514 onto the support wheel 515. The inclined support wheel 515 supports the bottom edge of the outer ring of the annular workpiece. When performing the inner ring gear shaping, to avoid affecting the inner ring of the thinner annular workpiece, it is necessary to adjust the workpiece. Subsequently, the clamping end 509 moves along with the slider 508. The fixture end 509 contacts the outer surface of the workpiece via the contact block 512. The contact block 512 and the fixture end 509 slide and compress the cavity groove 511 of the rubber pad block 510, causing the cavity groove 511 to deform and adapt to the curvature of the workpiece's outer ring. This increases the friction between the contact block 512 and the workpiece's outer ring. Combined with the engaging hinge blocks 513 on both sides of the fixture end 509, this increases the contact points for workpiece fixation. This structure achieves automatic centering and progressive clamping of the workpiece's outer ring, reducing manual intervention. The rolling support of the side wheels 515 reduces friction on the workpiece's bottom surface and simultaneously raises the workpiece, causing it to detach from the bottom contact surface. This avoids deformation and positioning errors caused by uneven force on the bottom or inner ring clamping adjustment of thin-sized ring workpieces, eliminating the need for frequent workpiece posture adjustments. At the same time, the compression deformation of the cavity groove 511 can adapt to the outer ring contour with different curvatures, increasing the contact area and friction between the contact block 512 and the outer ring of the workpiece, achieving elastic self-adhesive clamping, avoiding rigid clamping damage to the workpiece surface. In addition, the engaging hinge blocks 513 on both sides of the fixture end 509 increase the contact points for workpiece fixation, and the multi-point joint constraint significantly improves the workpiece's resistance to torsion and offset during the gear hobbing process, ensuring machining accuracy and stability.

[0022] The solid-liquid separation mechanism 6 includes a sliding rod 601, a lifting ring 602 fixedly connected to the bottom end of the sliding rod 601, a filter hood 603 fixedly connected to the inner side of the lifting ring 602, a sliding block 604 fixedly connected to the upper surface of the lifting ring 602, multiple torsion grooves 605 opened on the inner wall of the inclined chute turntable 501, and a hydraulic rod 606 rotatably connected below the axis of the filter hood 603.

[0023] A collection box 608 is fixedly connected to the bottom surface of the platform 2. A discharge port 609 is provided on the side of the collection box 608. An isolation cover ring 607 is fixedly connected to the middle of the inner side of the collection box 608. An infusion port 610 is provided on the bottom surface of the collection box 608.

[0024] The torsion chute 605 is slidably connected to the chute block 604, the hydraulic rod 606 is fixedly connected to the collection box 608, and the isolation cover ring 607 is slidably connected to the lifting ring 602. Before clamping the workpiece, the hydraulic rod 606 extends to push the connected filter hood 603 to move. The filter hood 603 drives the connected lifting ring 602 to push the sliding rod 601 upward and retract it into the swing rod turntable 504. At the same time, the lifting ring 602 slides along the torsion chute 605 through the chute block 604, allowing the inclined chute turntable 501 and the swing rod turntable 504 to rotate relative to each other in preparation for clamping. At this time, the filter hood 607 disengages from the isolation cover ring 607. The shroud ring 607 slides and adheres to the inner wall of the inclined chute turntable 501. When the built-in motor drives the drive worm 516 to rotate, the worm 516 meshes with the worm gear tooth groove 517 on the outer wall of the inclined chute turntable 501. At this time, the inclined chute turntable 501, after the workpiece is fixed, rotates slowly together with the swing arm turntable 504. The inclined chute turntable 501 drives the filter shroud 603 and the top of the hydraulic rod 606 to rotate through the connected sliding rod 601. The debris and coolant generated during the processing fall into the upper part of the filter shroud 603 through the middle of the swing arm turntable 504. The coolant flows into the isolation layer through the gaps on the surface of the filter shroud 603. Inside the shroud 607, the debris remains above the filter shroud 603. After processing, the hydraulic rod 606 retracts, releasing the workpiece from the clamping state. Simultaneously, the lifting ring 602 on the bottom side of the filter shroud 603 descends with the hydraulic rod 606, aligning with the top edge of the shroud 607. This allows the filter shroud 603 to slide into the outer periphery of the shroud 607 under the action of the inclined arc surface, separating the debris generated during gear hobbing from the coolant for easier subsequent processing. This structure achieves linkage between the clamping action and the movement of the filter assembly, simplifying the process flow. The filter shroud 603 is raised and pressed against the inner wall of the turntable, preparing for subsequent debris collection. With the chips and coolant prepared, the filter hood 603 and hydraulic rod 606 rotate synchronously during the workpiece rotation process, avoiding seal failure or structural interference caused by relative motion and ensuring the continuity of dynamic filtration. At the same time, solid-liquid separation is achieved by utilizing the gaps in the filter hood 603, preventing chips from mixing into the coolant circulation system and reducing the burden on subsequent filtration. In addition, the chips are concentrated and accumulated above the filter hood 603 by gravity and the inclined plane, and the coolant gathers inside the isolation ring 607, realizing the classification, collection and rapid cleaning of materials after processing, and improving maintenance convenience.

[0025] The spray linkage mechanism 7 includes a connecting rod 701. A through-box rod 702 is fixedly connected to the end of the connecting rod 701. A linkage rod 703 is fixedly connected to the bottom end of the through-box rod 702. An elastic rod 704 is slidably connected to the end of the linkage rod 703 away from the through-box rod 702. A sleeve block 705 is fixedly connected to the top end of the elastic rod 704. An infusion seat 706 is slidably connected to the inner side of the sleeve block 705. A threaded strip 707 is fixedly connected to the outer side of the infusion seat 706. A nozzle assembly 708 is fixedly connected to the top end of the infusion seat 706.

[0026] The connecting rod 701 is fixedly connected to the extension rod of the hydraulic rod 606. A thrust spring is provided on the outer side of the elastic rod 704, and the two ends of the thrust spring are fixedly connected to the sleeve block 705 and the linkage rod 703 respectively. The threaded strip 707 is threadedly connected to the sleeve block 705. The infusion seat 706 is rotatably connected to the platform 2. Before the workpiece is clamped, the nozzle assembly 708 connected to the infusion seat 706 is in its initial state. At this time, the nozzle assembly 708 does not affect the placement of the workpiece. When the workpiece is placed and ready to be clamped, the hydraulic rod 606 extends to drive the connecting rod. The movement of rod 701 causes connecting rod 701 to drive through rod 702 and linkage rod 703 downward together. The end of linkage rod 703 is compressed by a thrust spring and then pushes sleeve block 705 to move. Sleeve block 705 slides along the threaded strip 707 on the outside of infusion seat 706, causing infusion seat 706 to rotate around the connection of platform 2 and drive nozzle assembly 708 to deflect. After deflection, the end of nozzle assembly 708 is aligned with the position of gear cutting and sprays liquid to cool the cutting position. Meanwhile, the built-in pump body pumps the liquid in the isolation ring 607 through the pipe. The infusion port 610 delivers fluid to the bottom of the infusion seat 706, and then the infusion seat 706 delivers it to the end of the nozzle assembly 708. Utilizing the extension of the hydraulic rod 606 during the clamping action as a drive source, and through the sequential transmission of connecting rods and springs, the nozzle assembly 708 automatically deflects without the need for additional power or control components, reducing cost and failure rate. Simultaneously, the threaded strip 707 guides the sleeve block 705 to slide, allowing the infusion seat 706 to generate a precise rotational deflection angle, ensuring that the end of the nozzle assembly 708 can stably align with the tool and workpiece. The meshing area is cooled and lubricated at a fixed point, effectively reducing the cutting heat in the gear hobbing area. The built-in pump delivers the liquid in the isolation ring 607 to the bottom of the liquid delivery seat 706 through the liquid delivery port 610, and then from the liquid delivery seat 706 to the end of the nozzle assembly 708, realizing the recycling of coolant. The clean coolant separated and collected in the isolation ring 607 after machining is pumped back to the nozzle assembly 708, forming a closed cooling circuit, which significantly saves the amount of cutting fluid and ensures the continuity and stability of the spraying process.

[0027] Working principle: When the rocker arm turntable 504 rotates relative to the inclined groove turntable 501, the rocker arm turntable 504 pushes the vertical slide rod 503 along the guide rod 502 through the rocker arm groove 506, causing the vertical slide rod 503 to slide along the slide rod groove 505. At this time, the vertical slide rod 503 drives the connected slider 508 to slide along the track 507 and drive the clamping end 509 to approach the outer side of the annular workpiece. The movement of the clamping end 509 simultaneously drives the guide ring push plate 514 to move together. Through the inclined surface of the guide ring push plate 514, the annular workpiece is lifted upward from the bottom, so that the bottom surface of the ring slides along the guide ring push plate 514 onto the support wheel 515. The inclined support wheel 515 lifts the bottom edge of the outer ring of the annular workpiece. When the inner ring is being machined, this avoids affecting the inner ring of the thinner annular workpiece and thus requiring workpiece adjustment. Subsequently, the clamping end 509, which moves with the slider 508, contacts the outer surface of the workpiece through the contact block 512. The contact block 512 and the clamping end 509 slide and compress the cavity groove 511 of the rubber pad block 510, causing the cavity groove 511 to deform to match the curvature of the outer ring of the workpiece, thereby increasing the friction between the contact block 512 and the outer ring of the workpiece. This, combined with the engaging hinge blocks 513 on both sides of the clamping end 509, increases the contact points for fixing the workpiece. Before clamping the workpiece, the hydraulic rod 606 extends to push the connected filter hood 603 to move. The filter hood 603 drives the connected lifting ring 602 to push the sliding rod 601 upward and retract it into the swing rod turntable 504. At the same time, the lifting ring 602 slides along the torsion groove 605 through the sliding block 604, allowing the inclined groove turntable 501 and the swing rod turntable 504 to rotate relative to each other in preparation for clamping. At this time, the filter hood 603 slides away from the isolation cover ring 607 and fits against the inner wall of the inclined groove turntable 501. When the built-in motor drives the drive worm 516 to rotate, the worm 516 meshes with the worm gear tooth groove 517 on the outer wall of the inclined groove turntable 501. At this time, the inclined groove turntable 501 and the swing rod turntable 504 slowly rotate together after the workpiece is fixed. The turntable 501 drives the filter hood 603 and the top of the hydraulic rod 606 to rotate via the connected sliding rod 601. During the processing, the debris and coolant generated fall into the upper part of the filter hood 603 through the middle of the swing rod turntable 504. The coolant flows into the isolation ring 607 through the gaps on the surface of the filter hood 603, while the debris remains on the upper part of the filter hood 603. After the processing is completed, the hydraulic rod 606 retracts to release the workpiece from the clamping state. At the same time, the lifting ring 602 on the bottom side of the filter hood 603 descends with the hydraulic rod 606 and aligns with the top edge of the isolation ring 607, so that the filter hood 603 slides into the outer periphery of the isolation ring 607 under the action of the inclined arc surface, so that the debris and coolant generated during the gear hobbing process are stored separately for easy subsequent processing. Before the workpiece is clamped, the nozzle assembly 708 connected to the infusion seat 706 is in its initial state. At this time, the nozzle assembly 708 does not affect the placement of the workpiece. When the workpiece is placed and ready to be clamped, the hydraulic rod 606 extends and drives the connected connecting rod plate 701 to move. The connecting rod plate 701 drives the through rod 702 and the linkage rod 703 to move downward together. The end of the linkage rod 703 is compressed by the thrust spring and pushes the sleeve block 705 to move. The sleeve block 705 slides along the threaded strip 707 on the outside of the infusion seat 706, causing the infusion seat 706 to rotate around the connection of the platform 2 and drive the nozzle assembly 708 to deflect. After deflection, the end of the nozzle assembly 708 is aligned with the position of the gear hobbing and sprays liquid to cool the machining position. Meanwhile, the built-in pump body delivers the liquid in the isolation ring 607 through the infusion port 610 to the bottom of the infusion seat 706 through the pipeline, and then the infusion seat 706 delivers it to the end of the nozzle assembly 708.
