Description

Technical Field

[0001] This invention relates to the field of gear grinding technology, specifically to a vertical continuous grinding feed mechanism for gear manufacturing. Background Technology

[0002] In gear manufacturing, grinding is a crucial process for obtaining high-precision gear teeth. Existing gear grinding equipment mainly includes a worktable, a feed mechanism mounted on the worktable, and a cutting disc driven by a high-speed spindle. The feed mechanism is used to fix the gear blank to be processed and transport it towards the rotating cutting disc. Its typical structure is as follows: a motor frame and a feed drive are fixedly mounted on the worktable. A drive motor is mounted on the motor frame, and a fixed rod is connected to the output end of the drive motor. One end of the fixed rod is fitted with a clamping device for locking and fixing the gear blank. The clamping device... The inner hole of the gear blank is passed through and radial pressure is applied to its inner wall to clamp the workpiece. The drive motor rotates intermittently at a preset angle, and the control rod drives the gear blank to rotate to switch the processing position of different teeth. The feed drive controls the control rod and the gear blank to reciprocate along its axis. During grinding, the cutting grinding disc rotates at high speed, and the feed mechanism pushes the gear blank to the grinding disc to complete the grinding of a single tooth. Then the drive motor controls the gear blank to rotate by a tooth pitch angle, and the feed mechanism pushes it again to grind the next tooth. This cycle continues until all teeth are processed.

[0003] However, the above-mentioned feeding mechanism has the following technical limitations in actual mass production: After all the teeth of a single gear blank have been ground, the feeding mechanism needs to stop working. The operator must unload the finished gear from the clamping device and then clamp a new gear blank to be processed, or use a robotic arm to load and unload the material. Only then can the feeding mechanism be restarted for the next round of grinding, which is not convenient for continuous feeding. Secondly, since gear grinding requires continuous processing around the entire circle, in order to avoid the grinding area, clamping is generally carried out from the inner wall of the ring gear. In order to be compatible with gears of different inner diameter specifications, the clamping device is usually designed as a conical expansion sleeve structure. The conical expansion sleeve structure consists of several circumferentially distributed elastic petals forming a ring expansion sleeve, with a conical push rod inside. When the push rod is axially advanced... When the conical surface of the push rod contacts the inner wall of each elastic petal, it forces the petals to expand outward to press against the inner wall of the gear. In this structure, the effective compression area between the conical push rod and the elastic petals is only an annular line contact. That is, the actual contact pressure between the push rod conical surface and the inner wall of the petals is only generated in a narrow annular band. Other axial positions of the petals do not receive effective radial support force. As a result, the contact pressure between the outer wall of the expansion sleeve and the inner wall of the gear is unevenly distributed along the axial direction after expansion. The actual effective clamping area is much smaller than the axial length of the inner wall of the gear. During the grinding process, under the continuous action of the circumferential grinding force, the gear blank is very easy to slip circumferentially relative to the expansion sleeve, causing the position reference of the machined tooth surface and the tooth surface to be machined to shift, directly resulting in tooth pitch error. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a vertical continuous grinding feed mechanism for gear manufacturing, thereby solving the aforementioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a vertical continuous grinding feed mechanism for gear manufacturing, comprising a mounting base mounted on a gear grinding machine, a rotating seat rotatably mounted on the mounting base, fixed seats symmetrically slidably mounted on the rotating seat, a circular shell on one side of each of the two fixed seats, a clamping member for fixing the gear slidably mounted on the circular shell, a rotation adjustment member for controlling the contraction and expansion of the clamping member rotatably mounted inside the circular shell, a rotation telescopic member for controlling the rotation of the circular shell and the clamping member mounted on the rotating seat, the rotation telescopic member being used to adjust the angle during gear grinding, a power motor fixedly mounted on the mounting base, the output end of the power motor being fixedly connected to the lower end of the rotating seat, for controlling the position replacement of the two clamping members to achieve continuous feed, and a pusher for controlling the extension and retraction of the fixed seats at the machining station mounted on the mounting base.

[0006] Preferably, the gear grinding machine includes an operating table and a lifting seat disposed on one side of the operating table, and a cutting tool is mounted on the lifting seat.

[0007] Preferably, the rotating telescopic component includes a rotating column rotatably mounted on a fixed base and a dual-axis motor fixedly mounted on the rotating base. Rectangular rods are fixedly mounted on both working ends of the dual-axis motor. A rectangular groove is opened at one end of the rotating column located on the dual-axis motor. The two rectangular rods are slidably connected to the rectangular grooves corresponding to their respective positions.

[0008] Preferably, the clamping member includes two fixed housings that are slidably connected to the circular housing. The outer end of the circular housing is provided with a rectangular sliding opening. A rectangular block that is slidably connected to the rectangular sliding opening is fixedly installed on one side of the fixed housing, and two rotating rods are rotatably installed on the other side. A limit member is provided between the two rotating rods.

[0009] Preferably, the limiting component includes a rotating shaft fixedly installed at one end of the rotating rod, the rotating shaft being rotatably connected to the fixed housing, and an arc-shaped toothed block being fixedly installed at one end of the rotating shaft inside the fixed housing, with two corresponding arc-shaped toothed blocks meshing.

[0010] Preferably, the rotating adjustment component includes a turntable rotatably installed inside a circular housing. Two arc-shaped grooves are provided on one side of the turntable, and a slide rod is slidably connected in the arc-shaped groove. The slide rod is fixedly connected to a rectangular block corresponding to the position. A push rod is fixedly installed on the other side of the turntable. An opening is provided on the outer side of the rotating column. One end of the push rod passes through the opening and is slidably connected thereto. A locking bolt that abuts against the rotating column is threaded to the outer end of the push rod.

[0011] Preferably, the pushing component includes a cylinder fixedly mounted on a mounting base, a rectangular frame fixedly mounted on the working end of the cylinder, a U-shaped block fixedly mounted on the outer end of the rectangular frame, and an arc-shaped plate corresponding to the position of the U-shaped block fixedly mounted on the lower end of the mounting base.

[0012] Preferably, a telescopic cover is provided between the two rectangular blocks and between the rectangular blocks and the rectangular sliding sidewall.

[0013] Preferably, a ring for limiting the position of the arc-shaped plate is fixedly installed on the mounting base, and an outlet corresponding to the position of the arc-shaped plate is opened on one side of the ring.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. To achieve continuous feeding and loading / unloading of gear blanks during grinding, this invention uses two symmetrically arranged fixed seats, each equipped with a clamping device for fixing the gear blank. The clamping device located on the side of the cutting tool serves as the machining station, while the clamping device on the side away from the cutting tool serves as the loading / unloading station. The two clamping devices interchange positions by rotating a rotating seat. After the gear blank on one clamping device has completed all tooth grinding at the machining station, the rotating seat rotates 180 degrees, switching the pre-clamped blank to the machining station and immediately starting the next round of grinding. Simultaneously, the finished gear is switched to the loading / unloading station along with the other clamping device. At this station, the operator or an external robotic arm unloads the finished product and clamps the new blank. Through this continuous feeding method of alternating dual stations, the machining station can obtain a new blank after the finished gear has been ground without waiting for loading / unloading operations, allowing machining and loading / unloading to be performed simultaneously, thus achieving continuous feeding.

[0015] 2. To achieve reliable clamping of gear blanks with different inner diameters and avoid the risk of circumferential slippage due to limited contact area of ​​the inner wall, this invention rotatably mounts two rotating rods on a fixed housing via a rotating shaft. An arc-shaped toothed block is fixedly mounted at one end of the rotating shaft inside the fixed housing. Two corresponding arc-shaped toothed blocks mesh with each other. When clamping the gear blank, the two sets of four rotating rods pass through the center of the blank. Then, by rotating the adjusting component, the two fixed housings are controlled to move radially away from each other, causing the outer walls of the four rotating rods to simultaneously press against the inner wall of the gear blank. Radial multi-point support is used to lift and fix the blank. In this clamping state, when the gear blank is subjected to circumferential grinding force during grinding, it rotates. When the blank is in the trend, the inner wall of the blank will push multiple rotating rods on its inner side to rotate in the same direction. At this time, since the two corresponding arc-shaped tooth blocks mesh with each other, they are forced to rotate synchronously in opposite directions. When one rotating rod rotates in the positive direction with the rotation trend of the blank, the other rotating rod corresponding to it rotates in the opposite direction under the meshing constraint of the arc-shaped tooth block. The frictional force of the reverse rotating rod is opposite to the rotation trend direction of the blank, thus applying a reverse braking force to the gear blank. During the grinding process, the circumferential slippage of the blank is actively suppressed, effectively reducing the risk of slippage. Moreover, this clamping can adapt to different inner diameter sizes and can be adapted to various specifications of gear blanks without changing the clamping parts. Attached Figure Description

[0018] The embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings and examples. The detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of this disclosure by way of example, but should not be used to limit the scope of this disclosure. This disclosure can be implemented in many different forms and is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.

[0019] Please see Figures 1-7 A vertical continuous grinding feed mechanism for gear manufacturing includes a mounting base 3 mounted on a gear grinding machine. The gear grinding machine includes an operating table 1 and a lifting seat 30 mounted on one side of the operating table 1 (used to control the cutting tool 2 on it to move up and down to match the grinding of different gears). The cutting tool 2 is mounted on the lifting seat 30 (the cutting tool 2 is driven by a motor through a high-speed spindle to rotate at high speed and grind the moving gear blank). The above is the conventional configuration of existing gear grinding machines, and its working principle is well known to those skilled in the art. A rotating seat 6 is rotatably mounted on mounting base 3 (see...) Figure 2The rotating base 6 is symmetrically equipped with fixed bases 8 (two fixed bases 8 are symmetrically arranged with the axis of the rotating base 6 as the center). A circular housing 10 is provided on one side of each fixed base 8. A clamping component for fixing the gear is slidably mounted on the circular housing 10 (the clamping component on the side of the cutting tool 2 is the machining station, and the clamping component on the side away from the cutting tool 2 is the loading / unloading station). A rotation adjustment component for controlling the retraction and expansion of the clamping component is rotatably installed inside the circular housing 10. A rotation telescopic component for controlling the rotation of the circular housing 10 and the clamping component is installed on the rotating base 6. The rotation telescopic component is used to adjust the angle during gear grinding. A power motor 29 is fixedly mounted on the mounting base 3. The output end of the power motor 29 is connected to the lower end of the rotating base 6. The mounting base 3 is fixedly connected to a pusher for controlling the extension and retraction of the fixed base 8 at the machining station. After the gear at the machining station is finished, the power motor 29 is started to drive the rotating base 6 to rotate 180 degrees, switching the pre-clamped blank to be processed at the loading and unloading station to the machining station, and immediately entering the next round of grinding. At the same time, the finished gear is switched to the loading and unloading station along with another clamping component. The operator or an external robotic arm unloads the finished product and clamps the new blank at this station. Through the above-mentioned continuous feed method of alternating dual stations, the machining station can obtain a new blank to be processed without waiting for the loading and unloading operation after the finished gear is ground, so that machining and loading and unloading can be carried out simultaneously, realizing continuous feed.

[0020] To achieve reliable clamping of gear blanks with different inner diameters, the clamping device of this invention includes two fixed housings 21 slidably connected to a circular housing 10. A rectangular sliding opening 16 is provided at the outer end of the circular housing 10. A rectangular block 22 slidably connected to the rectangular sliding opening 16 is fixedly installed on one side of each fixed housing 21. (A telescopic cover 24, similar to an accordion cover, is provided between the two rectangular blocks 22 and between the rectangular block 22 and the side wall of the rectangular sliding opening 16. This cover is elastic, expandable, and retractable, used to seal the rectangular sliding opening 16 and prevent grinding debris from splashing into the circular housing 10.) Two rotating rods 4 are rotatably installed on the other side. A limiting element is provided between the two rotating rods 4. The limiting element includes a rotating shaft 26 fixedly installed at one end of each rotating rod 4. The rotating shaft 26 is rotatably connected to the fixed housing 21. When clamping the gear blank, the two sets of four rotating rods 4 pass through the center of the blank. Then, the two fixed housings 21 are controlled to move radially away from each other by a rotation adjustment component, so that the outer walls of the four rotating rods 4 simultaneously abut against the gear blank. The inner wall of the gear blank is supported and fixed by radial multi-point support. One end of the rotating shaft 26 is fixedly installed with an arc-shaped tooth block 27 inside the fixed housing 21. Two corresponding arc-shaped tooth blocks 27 mesh. In the above clamping state, when the gear blank is subjected to circumferential grinding force during grinding and has a tendency to rotate, the inner wall of the blank will push multiple rotating rods 4 on its inner side to have a tendency to rotate in the same direction. At this time, since the two corresponding arc-shaped tooth blocks 27 mesh with each other, they are forced to rotate synchronously in opposite directions. When one rotating rod 4 rotates in the positive direction with the rotation tendency of the blank, the other rotating rod 4 corresponding to it rotates in the opposite direction under the meshing constraint of the arc-shaped tooth block 27. The frictional force of the reverse rotating rod 4 is opposite to the rotation tendency direction of the blank, thereby applying a reverse braking force to the gear blank. During the grinding process, the circumferential slippage of the blank is actively suppressed, effectively reducing the risk of slippage. Moreover, this clamping can adapt to different inner diameter sizes and can be adapted to various specifications of gear blanks without changing the clamping parts.

[0021] As a further technical solution of the present invention, the rotating telescopic component includes a rotating column 7 rotatably mounted on a fixed base 8 and a dual-axis motor 9 fixedly mounted on a rotating base 6. Rectangular rods 13 are fixedly mounted on both working ends of the dual-axis motor 9. A rectangular groove 31 is opened at one end of the rotating column 7 located on the dual-axis motor 9. The two rectangular rods 13 are slidably connected to the rectangular grooves 31 corresponding to their positions. During the grinding process, after one tooth is processed, the dual-axis motor 9 is started to control the rectangular rods 13 to rotate according to a preset angle. The rectangular rods 13 drive the rotating column 7 to rotate. The rotating column 7 drives the four rotating rods 4 to rotate through the circular housing 10. The rotating rods 4 drive the gear blank to rotate by a preset angle to process the next tooth.

[0022] As a further technical solution of the present invention, the pushing component includes a cylinder 11 fixedly mounted on the mounting base 3. A rectangular frame 14 is fixedly mounted on the working end of the cylinder 11, and a U-shaped block 15 is fixedly mounted on the outer end of the rectangular frame 14. An arc-shaped plate 12 corresponding to the position of the U-shaped block 15 is fixedly mounted on the lower end of the fixed base 8 (the placement opening between the two side plates of the U-shaped block 15 mates with the arc-shaped plate 12). After the power motor 29 drives the rotating base 6 to rotate 180 degrees, not only is the position of the clamping component switched, but the clamping component is also... The position of the arc plate 12 on one side is switched, and the arc plate 12 on the side of the loading and unloading station is moved into the U-shaped block 15. During grinding, the cylinder 11 is started to push the rectangular frame 14 to move. The rectangular frame 14 pushes the arc plate 12 to move through the U-shaped block 15. The fixed seat 8 corresponding to the arc plate 12 is connected, so the gear blank on one side of the fixed seat 8 is pushed to move to perform grinding. At the same time, while the fixed seat 8 moves, the rectangular rod 13 slides in the rectangular slide groove 31 and remains in a state of never leaving the rectangular slide groove 31. A ring 5 is fixedly installed on the mounting base 3 to limit the arc plate 12. An outlet 28 corresponding to the position of the arc plate 12 is opened on one side of the ring 5. The outer arc surface of the arc plate 12 slides in contact with the inner arc surface of the ring 5. The ring 5 is used to limit the arc plate 12 when switching clamping parts, so as to ensure that the arc plate 12 can slide into the U-shaped block 15 each time it moves to the side of the processing station.

[0023] As a further technical solution of the present invention, the rotating adjustment component includes a turntable 17 rotatably installed inside a circular housing 10. Two arc-shaped grooves 19 are provided on one side of the turntable 17, and a slide rod 20 is slidably connected in the arc-shaped grooves 19. The slide rod 20 is fixedly connected to a rectangular block 22 corresponding to the position. A push rod 18 is fixedly installed on the other side of the turntable 17. An opening 23 is provided on the outer side of the rotating column 7. One end of the push rod 18 passes through the opening 23 and is slidably connected thereto. A locking bolt 25 (used to limit the push rod 18, but not limited to it) is threaded to the outer end of the push rod 18 and abuts against the rotating column 7. The push rod 18 can be rotated by using the locking bolt 25, or by installing a motor or electric push rod on the rotating column 7 to adjust the turntable 17 (when not in operation, it is also used to keep the push rod 18 stationary). By rotating the push rod 18, the turntable 17 is driven to rotate. The turntable 17 is driven to move by the cooperation of the arc-shaped slide groove 19 and the rectangular slide opening 16, controlling the two corresponding fixed housings 21 to move closer or further apart. When they are close together, they are used to pick up and put down the gear blank during the loading and unloading process. When they are far apart, they are used to fix the gear blank. Then the push rod 18 can be fixed.

[0024] During work: At the loading and unloading station, the limit on push rod 18 is released, and push rod 18 on circular housing 10 is rotated. Push rod 18 drives turntable 17 to rotate inside circular housing 10. Two arc-shaped slide grooves 19 on turntable 17 drive two rectangular blocks 22 to approach each other along rectangular slide opening 16 through slide rod 20. Rectangular blocks 22 drive fixed housing 21 and two sets of rotating rods 4 to retract inward synchronously. The operator or robotic arm places the gear blank to be processed around the four rotating rods 4, and then rotates the push rod 18. The push rod 18 drives the turntable 17 to rotate inside the circular housing 10. The two arc-shaped sliding grooves 19 on the turntable 17 drive the two rectangular blocks 22 to move away from each other along the rectangular sliding opening 16 through the sliding rod 20. The rectangular blocks 22 drive the fixed housing 21 and the two sets of rotating rods 4 to unfold outwards synchronously. The outer walls of the four rotating rods 4 simultaneously press against the inner wall of the gear blank, and the blank is supported and fixed by radial four-point support. When the gear blank is subjected to circumferential grinding force during the grinding process and has a tendency to rotate, the inner wall of the blank will push the multiple rotating rods 4 on its inner side to have a tendency to rotate in the same direction. At this time, since the two corresponding arc-shaped tooth blocks 27 mesh with each other, they are forced to rotate synchronously in opposite directions. When one rotating rod 4 rotates in the positive direction with the rotation tendency of the blank, the other rotating rod 4 corresponding to it rotates in the opposite direction under the meshing constraint of the arc-shaped tooth block 27. The frictional force of the reverse rotating rod 4 is opposite to the rotation tendency of the blank, thereby applying a reverse braking force to the gear blank. During the grinding process, the circumferential slippage of the blank is actively suppressed, effectively reducing the risk of slippage. Moreover, this clamping can adapt to different inner diameter sizes and can be adapted to gear blanks of various specifications without changing the clamping parts. After adjustment, tighten the locking bolt 25 at the outer end of the push rod 18 so that the locking bolt 25 abuts against the rotating column 7, locking the position of the push rod 18 and ensuring that the clamping force remains stable during the grinding process (if other electric limit components are used to control the rotation of the push rod 18, positioning can be performed later). (II) Dual-station switching stage After the gear blanks at the loading and unloading stations are clamped, the power motor 29 is started. The power motor 29 drives the rotating seat 6 to rotate 180 degrees, switching the blanks to be processed that have been clamped at the loading and unloading stations to the processing station. At the same time, the gears that have been processed at the processing station are switched to the loading and unloading stations for unloading (the loading and unloading here are operated according to the steps in the first stage). During the rotation of the rotating seat 6, the arc plate 12 at the lower end of one of the fixed seats 8 slides along the inner arc surface of the ring 5 on the mounting seat 3. The ring 5 guides and limits the arc plate 12 to ensure that it slides accurately into the U-shaped block 15 of the pusher. The arc plate 12 enters the placement opening of the U-shaped block 15 and completes the power docking. The other arc plate 12 moves along the ring 5 and disengages from the rectangular frame 14. (III) Grinding stage Start cylinder 11, the working end of cylinder 11 pushes rectangular frame 14 to move, rectangular frame 14 pushes arc plate 12 and fixed seat 8 to move towards cutting tool 2 through U-shaped block 15, fixed seat 8 drives clamping part and gear blank to make axial feed, at the same time, cutting tool 2 rotates at high speed under the drive of high speed spindle, when blank is pushed to cutting tool 2, the grinding of a single tooth is completed; During the axial movement of the fixed seat 8, the rectangular rod 13 at the working end of the dual-axis motor 9 slides in the rectangular slide groove 31 of the rotating column 7 to ensure uninterrupted power transmission. The rectangular rod 13 also maintains sliding engagement with the rectangular slide groove 31 to ensure that the power for subsequent stepping rotation is always available. After a single tooth is ground, the cylinder 11 retracts, driving the fixed seat 8 and the gear blank to retract and reset, disengaging from the cutting tool 2. Then, the dual-axis motor 9 is started, driving the rectangular rod 13 to rotate at a preset angle. The rectangular rod 13 drives the rotating column 7 to rotate through the rectangular slide groove 31. The rotating column 7 drives the four rotating rods 4 and the gear blank to rotate synchronously at a preset angle through the circular housing 10 and the fixed housing 21, aligning the next tooth to be processed with the cutting tool 2. After alignment, the cylinder 11 extends again to grind the next tooth. Following the above steps, the grinding of all the teeth in the circumferential direction of the gear blank is completed one by one. (iv) Continuous Cyclic Phase After all the teeth of the current gear blank are ground, the power motor 29 is started again, driving the rotating seat 6 to rotate 180 degrees, switching the gear that has been processed at the machining station to the loading and unloading station, and at the same time switching the next blank to be processed that has been pre-clamped at the loading and unloading station to the machining station. After switching, the above steps are repeated to achieve continuous cyclic processing.

These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of the invention in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of the invention without inventive effort, and these embodiments will all fall within the scope of protection of the claims of the present invention.
