Description

Technical Field

[0001] The invention belongs to the technical field of tooth grinding, and specifically relates to a gear grinding machine. Background Art

[0002] A gear grinder is a special machine tool used to grind gears, racks and other toothed parts on workpieces. It is usually used to manufacture, repair and maintain various gear transmission systems and gearboxes. The gear grinder can efficiently process precise tooth shapes to ensure accurate meshing and transmission efficiency of the gears. The gear grinder is a mechanical equipment used to trim and process gears or racks. Its function is to achieve the required accuracy and quality standards for the tooth surface, tooth shape and size of the gear or rack through grinding, cutting or other processing methods.

[0003] The prior art also proposes some solutions: for example, a patent application with publication number CN107378142A discloses a gear grinding tool, in which the outer conical surface of the inner ring of the expansion sleeve is abutted against the inner conical surface of the outer ring of the expansion sleeve. When the inner ring of the expansion sleeve and the outer ring of the expansion sleeve slide relative to each other, the inner ring of the expansion sleeve pushes the clamping arm of the outer ring of the expansion sleeve to expand evenly, so that the pad on the outer ring of the expansion sleeve abuts against the inner hole of the gear. The gear grinding tool provided by the present invention supports the gear by a pad, and the inner ring of the expansion sleeve and the outer ring of the expansion sleeve clamp and lock the inner hole of the gear. The clamping is stable. For large-modulus, high-precision gears, the axial clamping end face is pre-limited during the clamping process, and the outer ring of the expansion sleeve and the inner ring of the expansion sleeve radially lock the gear, which is easy to achieve positioning and can accurately control the machining accuracy of the gear.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand: the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 8 As shown, the present invention provides a technical solution: a gear grinding machine comprises a base plate 1, two placing plates 2 are arranged above the base plate 1, and a rack template 4 and a rack grinding plate 5 are arranged on the top of the two placing plates 2 respectively, the rack template 4 and the rack grinding plate 5 are fixed to the placing plate 2 by bolts, a grinding wheel 8 is arranged above the rack grinding plate 5, the outer wall of the rotating shaft of the grinding wheel 8 is rotatably connected with a fixing member 7, one side of the fixing member 7 is fixedly connected with a motor 6, the output shaft of the motor 6 is fixedly connected to the rotating shaft of the grinding wheel 8, a protective plate 9 is arranged on the upper half of the grinding wheel 8, and the protective plate 9 is fixedly connected to one side of the fixing member 7, a lifting component is arranged above the grinding wheel 8, and the lifting is used to drive the grinding wheel 8 to lift and lower, a linkage component is arranged above the rack template 4, and the linkage component is used to push the rack grinding plate 5 forward a distance of a tooth each time, and a sliding component is arranged below the placing plate 2, and the sliding component is used to allow the two placing plates 2 to slide simultaneously.

[0032] During operation: In the existing gear grinding machine, when grinding the teeth on the rack, the position of the rack plate is first fixed by a clamp, and then after grinding the first two teeth on the rack plate, the grinding wheel needs to be raised and adjusted to between the next two teeth for grinding. After grinding one tooth each time, the grinding wheel needs to be raised and readjusted, which increases the time consumption of the grinding cycle, and adjusting the grinding wheel position will cause processing interruption, and will also introduce human errors, affecting the processing accuracy. In the embodiment of the scheme, it should be noted that the scheme is applicable to grinding the teeth on the rack plate, and before grinding the rack plate, a finished rack plate that has been ground will be prepared, and the grinding condition of the rack plate after grinding will be compared for inspection. First, the rack template 4 and the rack grinding plate 5 are respectively placed on the two placement plates 2 and fixed by bolts, and then the sliding component pushes the first tooth on the rack grinding plate 5 to the bottom of the grinding wheel 8, and at the same time, the rack template 4 is pushed to the linkage component The motor 6 is then started, and its output shaft drives the grinding wheel 8 to rotate, and the teeth of the rack grinding plate 5 begin to be ground. When the first tooth is ground, the lifting assembly is started, and the lifting assembly drives the grinding wheel 8 to rise through the protective plate 9. During the rising process of the grinding wheel 8, the linkage assembly is driven to move, so that the rack grinding plate 5 moves forward a distance of a tooth, and then the lifting assembly drives the grinding wheel 8 to descend to grind the next group of teeth, and this is repeated, and each time the grinding wheel 8 rises, The next group of teeth on the rack grinding plate 5 that have not been ground can be moved to just below the grinding wheel 8, so that multiple teeth on the rack grinding plate 5 can be ground continuously. After the grinding is completed, the rack grinding plate 5 is disassembled and replaced with the next rack plate to be ground. Through the above embodiment, each time a tooth is ground, the rack grinding plate 5 will move forward a distance of a tooth during the rising process of the grinding wheel, thereby avoiding the need to adjust the position of the grinding wheel 8 during the grinding process, thereby improving the processing efficiency and the accuracy of the grinding.

[0033] like Figures 2 to 4 As shown, the lifting assembly includes two open fixed seats 13, and the two open fixed seats 13 are fixedly installed just above the base plate 1. The inner walls of the two open fixed seats 13 are rotatably connected with threaded rods 14, and the outer walls of the two threaded rods 14 are threadedly connected with sliders 12. The outer walls of the two sliders 12 are respectively slidably connected to the inner walls of the two open fixed seats 13, and a slide rod 11 is fixedly connected between the two sliders 12. A slide rod groove 10 is opened on one side of one of the open fixed seats 13, and one end of the slide rod 11 is slidably connected to the slide rod groove 10. A driving assembly is arranged above the open fixed seat 13, and the driving assembly is used to drive the two threaded rods 14 to rotate.

[0034] During operation: when it is necessary to drive the grinding wheel 8 to rise, start the driving assembly, which will drive the two threaded rods 14 to rotate. When the two threaded rods 14 rotate, they will drive the two sliders 12 to slide upward inside the open fixed seat 13. When the sliders 12 slide downward, they will drive the fixing member 7 to move downward through the slide rod 11, and the fixing member 7 will drive the grinding wheel 8 to rise. Through the above embodiment, the effect of driving the grinding wheel 8 to rise and fall is achieved.

[0035] like Figures 2 to 3 As shown, the driving assembly includes a connecting plate 18, a dual-output motor 17 is fixedly mounted above the connecting plate 18, the output shafts at both ends of the dual-output motor 17 are fixedly connected to driving bevel gears 16, the teeth of the two driving bevel gears 16 are respectively meshed with driven bevel gears 15, and the two driven bevel gears 15 are fixedly connected to the top of the threaded rod 14.

[0036] During operation: start the dual-output motor 17, and the output shafts at both ends thereof will respectively drive the two driving bevel gears 16 to rotate, and the rotation of the two driving bevel gears 16 will drive the driven bevel gear 15 to rotate, and the rotation of the driven bevel gear 15 will drive the threaded rod 14 to rotate, and the rotation of the threaded rod 14 can achieve the effect of lifting and lowering the slider 12. Through the above embodiment, the effect of driving the slider 12 to slide up and down inside the open fixed seat 13 is achieved.

[0037] like Figures 5 to 7 As shown, the linkage assembly includes a clamping member 28, the inner wall of the bottom end of the clamping member 28 is rotatably connected to a disc 31, the outer wall of the disc 31 is fixedly connected to a raised triangle 32, the raised triangle 32 is meshed with the teeth of the rack template 4, and a transmission assembly is provided on one side of the disc 31, and the transmission assembly is used to drive the disc 31 to rotate one circle.

[0038] During operation: when the grinding wheel 8 rises, it will drive the disc 31 to rotate one circle through the transmission assembly. When the disc 31 rotates one circle, the protruding triangle 32 will cause the rack template 4 to move forward a distance of one tooth. Since the tooth spacing between the rack template 4 and the rack grinding plate 5 is the same, the rack template 4 will also drive the rack grinding plate 5 to move forward a distance of one tooth, so that the next group of unground teeth of the rack grinding plate 5 moves to directly under the grinding wheel 8. Through the above embodiment, the effect of grinding each tooth of the rack grinding plate 5 is achieved without adjusting the position of the grinding wheel 8.

[0039] like Figures 5 to 7 As shown, the inner wall of the top end of the clamp 28 is rotatably connected to the gear 27, the disc 31 and one end of the gear 27 are fixedly connected to a transmission ring 29, the outer walls of the two transmission rings 29 are transmission-connected with a transmission belt 30, and the bottom of the clamp 28 is fixedly installed on the top of the base plate 1.

[0040] During operation: when the transmission assembly moves, it will first drive the gear 27 to rotate one circle. When the gear 27 rotates one circle, it will drive the disc 31 to rotate one circle through the transmission ring 29 and the transmission belt 30. When the disc 31 rotates only one circle, the rack grinding plate 5 can move forward a distance of one tooth.

[0041] like Figures 5 to 7 As shown, the transmission assembly includes a V-shaped fixing member 19, one side of the V-shaped fixing member 19 is fixedly connected to one end of the sliding rod 11, both ends of the V-shaped fixing member 19 are fixedly connected to connecting rods 22, the outer walls of the two connecting rods 22 are slidably connected to sliding connecting members 23, and one side of the two sliding connecting members 23 is fixedly connected to a rack plate 26, the teeth of the rack plate 26 are meshed with the teeth of the gear 27, and the number of teeth of the rack plate 26 and the gear 27 are the same.

[0042] During operation: when the slider 12 drives the grinding wheel 8 to move upward, the slide bar 11 will also move upward. When the slide bar 11 moves upward, it will drive the rack plate 26 to move upward through the connecting rod 22 and the sliding connection 23. When the rack plate 26 moves upward, it will drive the gear 27 to rotate one circle. Through the above embodiment, when the lifting assembly moves, the slide bar 11 drives the gear 27 to rotate one circle, so that the disc 31 drives the rack template 4 to move forward by the distance of one tooth.

[0043] like Figures 5 to 7 As shown, a magnet three 25 is fixedly connected to the middle part of one side of the rack plate 26, and a magnet block one 20 and a magnet block two 21 are fixedly installed above and below one side of an opening fixing seat 13, the side of the magnet three 25 close to the magnet block one 20 is the same pole, and the side of the magnet block two 21 close to the magnet three 25 is the opposite pole, and the outer walls of the two connecting rods 22 are symmetrically fixedly connected to the limited position cone 24.

[0044] During operation: when the rack plate 26 rises to the highest point, the position of the magnet three 25 is flush with the magnet block 1 20. Since the side of the magnet three 25 and the magnet block 1 20 that are close to each other are of the same pole, the magnet block 1 20 will repel the magnet three 25, so that the sliding connection 23 drives the rack plate 26 to slide to the side away from the magnet block 1 20. When the grinding wheel 8 descends for grinding, the rack plate 26 cannot mesh with the gear 27 during the descending process, so that the gear 27 rotates. When the rack plate 26 descends to the lowest point, the position of the magnet three 25 is flush with the magnet block 21. Since the side of the magnet block 21 and the magnet block 1 20 that are close to each other are of different poles, the magnet block 1 20 will attract the magnet three 25, so that the sliding connection 23 drives The rack plate 26 slides toward the side close to the magnet block 21, so that the rack plate 26 can mesh with the gear 27 during the rising process, so that the gear 27 rotates, wherein the connecting rod 22 limits the sliding position of the rack plate 26, so that the rack plate 26 will not be separated from the connecting rod 22 when it is far away from sliding, and the rack plate 26 can mesh with the gear 27 when it is close to the sliding position. Through the above embodiment, the rack plate 26 will not drive the gear 27 to rotate when it descends, but can drive the gear 27 to rotate during the rising process, thereby realizing the normal movement of the transmission component, and achieving the effect of driving the rack template 4 to move forward a tooth distance during the rising process of the grinding wheel 8, and not driving the rack template 4 to move during the descending process.

[0045] like Figure 1 and Figure 8 As shown, the sliding assembly includes two inner groove fixing seats 34, and the two inner groove fixing seats 34 are fixedly installed directly above the base plate 1. The bottoms of the two placement plates 2 are fixedly connected with moving blocks 33, and the two moving blocks 33 are respectively slidably connected to the inner walls of the two inner groove fixing seats 34, and a connecting handle 35 is fixedly connected between one side of the two placement plates 2.

[0046] During operation: when the rack template 4 slides, the bottom placement plate 2 will slide on the inner wall of the inner groove fixing seat 34 through the moving block 33, and will drive the rack grinding plate 5 to slide through the connecting handle 35, so that each time the rack template 4 moves, the rack grinding plate 5 can slide along with the rack template 4, and through the sliding cooperation between the moving block 33 and the inner groove fixing seat 34, the rack template 4 drives the rack grinding plate 5 to slide more stably.

[0047] like Figure 1 to Figure 2 As shown, a water tank 36 is fixedly connected to the outer wall of one of the opening fixing seats 13, and the water pipe outlet of the water tank 36 is aligned with the grinding teeth.

[0048] During operation: Since a large amount of heat is generated during the grinding process, the grinding teeth are cooled by the water tank 36 to prevent the grinding temperature from being too high and causing the teeth to break.

[0049] like Figure 1 and Figure 8 As shown, water flow slopes 37 are provided on both sides of the top surface of one of the placement plates 2, a water outlet pipe 38 is fixedly connected to one side of one of the inner groove fixing seats 34, and a water outlet pipe 38 is fixedly installed on one side of the bottom plate 1, and the outlet of the water outlet pipe 38 is located directly above the collection box 3.

[0050] During operation: when the water in the water tank 36 cools the grinding teeth, the water will take away most of the grinding debris, and slide into the inner groove fixing seat 34 through the water flow slope 37, and then flow into the collection box 3 from the water outlet pipe 38 on one side of the inner groove fixing seat 34, thereby achieving the effect of collecting water and part of the debris.

[0051] Working process: First, place the rack template 4 and the rack grinding plate 5 on the two placement plates 2 respectively and fix them with bolts, push the first tooth on the rack grinding plate 5 to the bottom of the grinding wheel 8 through the connecting handle 35, and also push the rack template 4 to the bottom of the linkage assembly, then start the motor 6, its output shaft will drive the grinding wheel 8 to rotate, and start grinding the teeth of the rack grinding plate 5.

[0052] Secondly, when the grinding of the first tooth is completed, the dual-output motor 17, the output shafts at both ends of which will respectively drive the two driving bevel gears 16 to rotate, the rotation of the two driving bevel gears 16 will drive the driven bevel gear 15 to rotate, and the rotation of the driven bevel gear 15 will drive the threaded rod 14 to rotate. When the two threaded rods 14 rotate, they will drive the two sliders 12 to slide upward inside the open fixed seat 13. When the slider 12 slides downward, it will drive the fixing part 7 to move downward through the slide rod 11, and the fixing part 7 will drive the grinding wheel 8 to rise.

[0053] Then, when the slider 12 drives the grinding wheel 8 to move upward, the slide bar 11 will also move upward. When the slide bar 11 moves upward, it will drive the rack plate 26 to move upward through the connecting rod 22 and the sliding connection 23. When the rack plate 26 moves upward, it will drive the gear 27 to rotate one circle. When the gear 27 rotates one circle, it will drive the disc 31 to rotate one circle through the transmission ring 29 and the transmission belt 30. When the disc 31 rotates one circle, it will cause the rack template 4 to move forward a distance of one tooth through the raised triangle 32. Since the tooth spacing of the rack template 4 and the rack grinding plate 5 is the same, the rack template 4 will also drive the rack grinding plate 5 to move forward a distance of one tooth, so that the next group of unground teeth of the rack grinding plate 5 moves to just below the grinding wheel 8, thereby continuously grinding multiple teeth on the rack grinding plate 5. After the grinding is completed, the rack grinding plate 5 is disassembled and replaced with the next rack plate to be ground.

[0054] At the same time, when the rack plate 26 rises to the highest point, the position of the magnet three 25 is flush with the magnet block 1 20. Since the adjacent sides of the magnet three 25 and the magnet block 1 20 are of the same pole, the magnet block 1 20 will repel the magnet three 25, so that the sliding connection 23 drives the rack plate 26 to slide to the side away from the magnet block 1 20. When the grinding wheel 8 descends for grinding, the rack plate 26 cannot mesh with the gear 27 during the descending process, so that the gear 27 rotates. When the rack plate 26 descends to the lowest point, the position of the magnet three 25 will be flush with the magnet block 2 21 is flush, and since the adjacent sides of magnet block 21 and magnet block 1 20 are of opposite poles, magnet block 1 20 will attract magnet 3 25, so that the sliding connection 23 drives rack plate 26 to slide toward the side close to magnet block 21, so that rack plate 26 can mesh with gear 27 during the rising process, so that gear 27 can rotate, wherein the connecting rod 22 limits the sliding position of rack plate 26, so that rack plate 26 will not be separated from connecting rod 22 when it slides away, and the position of rack plate 26 after sliding can mesh with gear 27.

[0055] Finally, when the rack template 4 slides, the bottom placement plate 2 will slide on the inner wall of the inner groove fixing seat 34 through the moving block 33, and will drive the rack grinding plate 5 to slide through the connecting handle 35. Through the sliding cooperation between the moving block 33 and the inner groove fixing seat 34, the rack template 4 drives the rack grinding plate 5 to slide more stably. A large amount of heat will be generated during the grinding process. The grinding teeth will be cooled by the water tank 36. Most of the grinding debris will be taken away by the water, and will slide into the inner groove fixing seat 34 through the water flow slope 37, and then flow into the collection box 3 from the outlet pipe 38 on one side of the inner groove fixing seat 34.
