Description

Technical Field

[0001] This invention relates to the field of gear grinding technology, specifically to a gear internal hole grinding device based on intelligent manufacturing. Background Technology

[0002] In the gear manufacturing process, round hole grinding is a key process to ensure gear accuracy and fit performance. The stability of the fixture directly affects the processing quality. In the existing technology, the diameter of the gear is usually clamped, which lacks the effect of clamping gears of different heights. This leads to the easy deformation of thin-walled gears during grinding, while thick gears are not clamped firmly, and may even cause vibration marks or dimensional deviations.

[0003] Patent CN221210963U discloses a gear-hole grinding fixture. This patent includes a base, a grinding rod, a clamping sleeve, fastening components, and a gear block. A motor is fixed to one side of the top of the base, and the clamping sleeve is fixed to the other side of the top of the base. The motor's connection end is connected to a drive assembly. A set of evenly distributed fastening components in a ring is fixed to the periphery of the clamping sleeve. The gear block is clamped inside the clamping sleeve and is limited by the set of fastening components. The grinding rod can be moved inward or outward by the electric telescopic rod of the drive assembly, enabling the grinding fixture to be adjusted according to the gear hole. The diameter of the round hole in the block adjusts the position of the grinding rod, which facilitates automatic adjustment of the grinding diameter. It is suitable for different diameters of the round holes of gears, improving adjustability. In addition, a fastening component is provided, which can first move the adjusting part inward or outward on the adjusting plate, and then lock the position of the adjusting part with a nut, which is convenient for locking gears of different thicknesses and improving adjustability. Although this patent solves the above problems, it still lacks the effect of clamping gears of different heights, which makes thin-walled gears easy to deform during grinding, while thick gears are not clamped firmly, and may even cause vibration marks or dimensional deviations.

[0022] 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.

[0023] Please see Figures 1-7One embodiment of the present invention is: a gear internal hole grinding processing device based on intelligent manufacturing, used for clamping gears that need to be ground into circular holes, including a chuck 1 for placing the gear, a linear motor 2 fixedly connected to the lower surface of the chuck 1, an L-shaped support plate 3 fixedly connected to the upper surface of the chuck 1, a spindle 4 rotatably connected to the inner surface of the L-shaped support plate 3, and a threaded groove opened at the bottom end of the circumferential surface of the spindle 4, a T-shaped slider 5 slidably connected to the inner surface of the chuck 1, and a U-shaped clamping plate 6 fixedly connected to the upper surface of the T-shaped slider 5, the U-shaped clamping plate 6 being used to clamp the circumferential surface of the gear and prevent jamming. The chip-prevention device 7 is located below the chuck 1. This device prevents grinding chips from falling into the clamping gaps and affecting the device's performance. The cooling device 8 is also located below the chuck 1 and sprays coolant onto the grinding area of ​​the gear's circular hole for cooling. The U-shaped clamping plate 6 approaches and clamps the gear's circumference, limiting its clamping and making the grinding process more stable and precise. Controlling the T-shaped slider 5 and the U-shaped clamping plate 6 stops facilitates clamping gears of different diameters, improving the device's applicability. The chuck 1 includes a mounting nut 9, which is threaded onto the circumference of the spindle 4. A sliding plate 10 is fixedly connected to the lower surface of the chuck 1. An adjusting rod 11 is slidably connected to the inner surface of the sliding plate 10. A grinding roller 12 is fixedly connected to the circumferential surface of the adjusting rod 11. The chuck 1 also includes a lifting slider 13, which is slidably connected to the inner surface of the U-shaped clamp 6. A jaw 14 is fixedly connected to the side of the lifting slider 13 closest to the grinding roller 12. A collar 15 is fixedly connected to the end of the lifting slider 13 away from the jaw 14. A connecting plate 16 is fixedly connected to the side of the U-shaped clamp 6 away from the jaw 14. A screw 17 is fixedly connected to the lower surface of the connecting plate 16. A grooved nut 1 is threaded onto the circumferential surface of the screw 17. 8. A motor is fixedly connected to the top of the main shaft 4, and the motor is fixedly connected to the upper surface of the L-shaped support plate 3. The bottom end of the screw 17 is fixedly connected to the upper surface of the T-shaped slider 5. The collar 15 and the inner surface of the grooved nut 18 are rotatably connected. The T-shaped slider 5 and the moving end of the linear motor 2 are fixedly connected. The lifting slider 13 drives the chuck 14 to move up and down and finally fits against the upper surface of the gear. Thus, the upper and lower sides of the gear are clamped by the chuck 14 and the chuck 1, which improves the clamping stability. Furthermore, by rotating the grooved nut 18 to adjust the height of the chuck 14, gears of different thicknesses can be clamped, further improving the applicability of the device.

[0024] Working principle: The gear is placed on the chuck 1, then the adjusting rod 11 and grinding roller 12 are inserted into the gear's circular hole, and the mounting nut 9 is rotated onto the spindle 4. At this time, the linear motor 2 is started, which drives the T-shaped slider 5 to slide within the chuck 1 and approach the gear. The T-shaped slider 5 drives the U-shaped clamping plate 6 to approach and clamp the gear's circumference, limiting the gear's clamping position and making the gear grinding process more stable and precise. When the U-shaped clamping plate 6 is in contact with the gear's circumference, the linear motor 2 is turned off, thereby stopping the T-shaped slider 5 and the U-shaped clamping plate 6. This facilitates clamping gears of different diameters, improving the device's applicability. After the U-shaped clamping plate 6 clamps the gear, it pushes the adjusting rod 11 to slide on the slide plate 10, thus fitting the inner diameter of the gear's circular hole, facilitating the clamping of gears with different inner diameters. The gear is being ground. At this time, the motor is started, and the motor drives the main shaft 4 and the sliding plate 10 to rotate. The sliding plate 10 drives the adjusting rod 11 and the grinding roller 12 to rotate circumferentially and grind the round hole. The groove nut 18 is rotated, and the groove nut 18 moves up and down on the circumferential surface of the screw 17 through the thread. When the groove nut 18 moves up and down, it drives the collar 15 to move up and down. The collar 15 drives the lifting slider 13 to slide up and down in the U-shaped clamp 6. The lifting slider 13 then drives the chuck 14 to move up and down and finally fit against the upper surface of the gear. Thus, the upper and lower sides of the gear are clamped by the chuck 14 and the chuck 1, which improves the clamping stability. Moreover, by rotating the groove nut 18 to adjust the height of the chuck 14, gears of different thicknesses can be clamped, which further improves the applicability of the device.

[0025] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, the anti-chip jamming device 7 includes a support side plate 71, which is fixedly connected to the lower surface of the chuck 1. An annular baffle 72 is fixedly connected to the bottom end of the support side plate 71. A material discharge groove 73 is opened inside the chuck 1 to prevent grinding chips from falling onto the chuck 1. A perforated partition 74 is fixedly connected to the inner surface of the annular baffle 72. Multiple through holes are opened on the inner side of the perforated partition 74. Metal chips fall through the material discharge groove 73 opened inside the chuck 1 and fall between the annular baffle 72 and onto the perforated partition 74. This prevents metal chips from falling directly onto the chuck 1 after generation and into the gaps of the clamp, causing jamming during clamping. It also prevents the clamping force of the clamp from being reduced due to the accumulation of metal chips, thereby improving the clamping effect of the device in long-term use. The anti-chip jamming device 7 also includes a chip guide cone 75. A transmission plate 76 is slidably connected to the inner surface of the bottom end of the adjusting rod 11, and a slanted scraper 77 is fixedly connected to the lower surface of the transmission plate 76. A horizontal scraper 78 is fixedly connected to the bottom end of the slanted scraper 77, and a scraper shovel 79 is fixedly connected to the front side of the horizontal scraper 78. The slanted scraper 77 abuts against the conical surface of the guide cone 75, the horizontal scraper 78 abuts against the upper surface of the porous partition 74, and the scraper shovel 79 abuts against the upper surface of the porous partition 74. The linear motor 2 is fixedly connected to the inner surface of the top of the support side plate 71. The slanted scraper 77 rotates circumferentially and scrapes the metal debris adhering to the conical surface of the guide cone 75, facilitating the collection of metal debris for subsequent processing. The horizontal scraper 78 rotates circumferentially on the porous partition 74 and pushes the metal debris together. After being pushed by the horizontal scraper 78, the metal debris is concentrated in the scraper shovel 79, improving the efficiency of metal debris collection and further enhancing the convenience of processing.

[0026] Working principle: Metal chips generated during the grinding of gear holes fall through the material discharge groove 73 on the inner side of the chuck 1 onto the space between the annular baffles 72 and the perforated partition 74. This prevents metal chips from falling directly onto the chuck 1 and into the gaps of the clamp, which could cause jamming during use. It also prevents the clamping force of the clamp from being reduced due to the accumulation of metal chips, thus improving the clamping effect of the device in long-term use. The metal chips falling from the center of the material discharge groove 73 fall onto the chip guide cone 75, and then slide along the conical surface... The metal scraps fall onto the porous partition 74. When the adjusting rod 11 rotates, it drives the transmission plate 76 to rotate. The transmission plate 76 drives the inclined scraper 77 to rotate and scrape the metal scraps adhering to the conical surface of the chip guide cone 75, making it easier for the metal scraps to be collected for subsequent processing. The inclined scraper 77 drives the horizontal scraper 78 to rotate on the porous partition 74 and pushes the metal scraps together. After being pushed by the horizontal scraper 78, the metal scraps are concentrated in the chip scraper 79, which improves the efficiency of metal scrap collection and further enhances the convenience of processing.

[0027] Please see Figures 1-7 In another embodiment of the present invention, based on the above embodiments, the cooling device 8 includes a nozzle 81, which is disposed above the chip guide cone 75. The nozzle 81 is used to spray coolant onto the grinding roller 12 and the inner wall of the gear hole. A support frame 82 is fixedly connected to the inner wall of the chip guide cone 75, and a fixing sleeve 83 is fixedly connected to the inner surface of the support frame 82. The nozzle 81 sprays coolant onto the inner diameter of the gear hole and the grinding roller 12 to cool the grinding area and improve the grinding effect. The sprayed coolant eventually drips onto the porous partition 74, and then separates from the metal chips through the through holes in the porous partition 74 and falls into the recycling sleeve 87 for collection, facilitating recycling. The cooling device 8 also includes a liquid infusion hose 84, which is fixedly connected to the inner wall of the fixing sleeve 83. A rotating ring 85 is fixedly connected to the nozzle 81. At the bottom, a rotating sleeve 86 is fixedly connected to the lower surface of the rotating ring 85, and a recovery sleeve 87 is fixedly connected to the lower surface of the annular baffle 72. The recovery sleeve 87 is used to recover the coolant after absorbing heat. The rotating sleeve 86 is rotatably connected to the inner surface of the top of the chip guide cone 75. The rotating sleeve 86 and the fixed sleeve 83 are rotatably connected to the circumferential surface. The transmission clamp 76 is fixedly connected to the circumferential surface of the rotating ring 85. The infusion hose 84 penetrates into the recovery sleeve 87 from the right side of the circumferential surface. The lower surface of the rotating ring 85 abuts against the bottom end of the chip guide cone 75. The fixed sleeve 83 is rotatably connected to the inner wall of the nozzle 81. The transmission clamp 76 rotates circumferentially with the adjusting rod 11 so that the nozzle 81 is always aligned with the contact point between the grinding roller 12 and the inner diameter of the gear hole to spray, thereby improving the cooling efficiency and thus improving the grinding efficiency.

[0028] Working principle: Coolant is introduced into the fixed sleeve 83 through the infusion hose 84. The coolant in the fixed sleeve 83 then enters the nozzle 81 and is sprayed onto the inner diameter of the gear hole and the grinding roller 12 to cool the grinding area and improve the grinding effect. The sprayed coolant drips into the porous partition 74 and is separated from the metal chips through the through holes in the porous partition 74 and falls into the recycling shell 87 for collection, which is convenient for recycling. When the transmission plate 76 rotates, it drives the rotating ring 85 to rotate. The rotating ring 85 drives the rotating sleeve shaft 86 to rotate in the chip guide cone 75. The rotation of the rotating ring 85 drives the nozzle 81 to rotate. The transmission plate 76 rotates with the adjusting rod 11 so that the nozzle 81 is always sprayed at the contact point between the grinding roller 12 and the inner diameter of the gear hole, which improves the cooling efficiency and thus improves the grinding efficiency.
