DETAILED DESCRIPTION

[0049] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0050] The present invention provides the following preferred embodiments:

[0051] Embodiment 1, as Figure 1-Figure 13As shown, a high-efficiency gear shaping machine includes a base 11, a processing table 12 is fixed on the top of the base 11, a support column 48 installed above the base 11 is provided on one side of the processing table 12, and also includes a cutting mechanism, a knife letting mechanism, a spraying mechanism and a plurality of three-jaw chucks 15, the plurality of three-jaw chucks 15 are equidistantly arranged above the processing table 12, each of the three-jaw chucks 15 is installed with a tooth embryo, the three-jaw chuck 15 is used for fixing and installing the tooth embryo to be processed, and ensuring the stability of the tooth embryo during the processing process, the three-jaw chuck 15 is a prior art, and will not be specifically described here;

[0052] The cutting mechanism includes a gear shaping cutter 51, a lifting assembly and a rotating assembly. The gear shaping cutter 51 is located in the middle of the upper part of the plurality of three-jaw chucks 15. By arranging a plurality of three-jaw chucks 15 above the processing table 12, each three-jaw chuck 15 can realize the fixed installation of a tooth blank. At the same time, the gear shaping cutter 51 is located between the plurality of three-jaw chucks 15. Therefore, a gear shaping cutter 51 can be used to synchronously shape a plurality of tooth blanks, thereby realizing batch processing of gears, which can solve the problem that the prior art can only realize the processing of one gear at a time and the processing efficiency is low. The lifting assembly is installed on the The gear shaping cutter 51 and the support column 48 are used to drive the gear shaping cutter 51 to move up and down. The lifting component can drive the gear shaping cutter 51 to move up and down. When the gear shaping cutter 51 moves downward, the gear shaping cutter 51 can be cut and processed. The rotating component is located between the lifting component and the support column 48. When the rotating component is working, it can drive the gear shaping cutter 51 to rotate. When the gear shaping cutter 51 is cutting the gear embryo, that is, when the gear shaping cutter 51 contacts the gear embryo, the rotating component is used to drive the gear shaping cutter 51 to rotate. At this time, the rotating component can drive the rotation of the tooth embryo in contact with the gear shaping cutter 51, so as to realize the processing of the outer wall of the tooth embryo.

[0053] The tool letting mechanism includes a telescopic component, a driving component, a plurality of slide grooves 13 and a plurality of sliders 14. Each slide groove 13 is located below a three-jaw chuck 15 and is opened on the surface of the processing table 12. Each slider 14 is slidably arranged inside a slide groove 13. The top of each slider 14 is fixedly connected to a three-jaw chuck 15. The telescopic component is located between the processing table 12 and the plurality of sliders 14. When working, the telescopic component can drive the plurality of sliders 14 to slide inside the plurality of slide grooves 13 respectively, thereby driving the plurality of three-jaw chucks 15 to synchronously move away from or close to the gear shaping cutter 51. The driving component is installed between the processing table 12 and the telescopic component. The driving component is used to drive the telescopic component to work and realize the movement of the three-jaw chuck 15.

[0054] In the initial state, the part to be processed of each tooth embryo is located below the gear shaping cutter 51, which is convenient for the gear shaping cutter 51 to move downward to process the tooth embryo. Then, before the gear shaping cutter 51 moves upward after shaping, that is, before retracting, the driving component drives the telescopic component to work, so that the multiple three-jaw chucks 15 move synchronously to the side away from the gear shaping cutter 51, which plays a role of avoidance, so that the gear shaping cutter 51 will not contact the tooth embryo on the three-jaw chuck 15 when retracting, which can effectively prevent the surface of the processed tooth embryo from being scratched during the retracting process, reduce the wear of the gear shaping cutter 51, and is conducive to improving the gear processing quality, and at the same time can also increase the service life of the gear shaping cutter 51;

[0055] The spray mechanism includes a filter basket 59, a storage chamber 46, a conveying assembly, a plurality of swing assemblies, a plurality of transmission assemblies, a plurality of shunt pipes 38 and a plurality of nozzles 40. The storage chamber 46 is opened inside the base 11, and the storage chamber 46 is connected to the inner cavity of the processing table 12. The storage chamber 46 is pre-stored with water for washing debris. The filter basket 59 is plugged into the middle of the surface of the processing table 12. Specifically, the processing position of the tooth embryo is located above the filter basket 59, and the bottom end of the filter basket 59 extends into the storage chamber 46. The filter basket 59 is a bowl-shaped grid structure, and the sprayed The water can wash the debris generated by the processing, and then the water can flow into the interior of the filter basket 59 with the debris. The filter basket 59 can filter the debris so that the debris can be collected inside the filter basket 59, which is convenient for subsequent recycling. At the same time, the filtered water can flow into the storage chamber 46 again, which can realize the recycling of water and is conducive to saving water resources. Each shunt pipe 38 is located on one side above a three-jaw chuck 15, and each two nozzles 40 are installed on both sides of the surface of a shunt pipe 38. The conveying component is installed between the storage chamber 46 and multiple shunt pipes 38 The conveying assembly can convey the cooling water stored in the storage chamber 46 to the plurality of shunt pipes 38 and spray the cooling water to the processing position of the tooth blank by the nozzle 40. On the one hand, the debris generated by the processing can be cleaned to prevent the debris from scratching the tooth blank and wearing the gear shaping cutter 51. On the other hand, due to the low water temperature, the cooling effect of the tooth blank and the gear shaping cutter 51 during the processing can be achieved, which is beneficial to improve the service life of the gear shaping cutter 51. Each swing assembly is located on the side of the shunt pipe 38 away from the gear shaping cutter 51, and each transmission assembly is located between a slider 14 and a swing assembly. By setting up multiple transmission components, when the three-jaw chuck 15 moves to avoid the gear shaping cutter 51, the transmission component can drive the swing component to work, and can drive the nozzle 40 on the shunt pipe 38 to rotate, and adjust the angle of the nozzle 40, that is, when the three-jaw chuck 15 moves, the nozzle 40 can be driven to rotate, and the nozzle 40 can rotate with the movement of the tooth embryo, so that the nozzle 40 can always face the processing part of the tooth embryo on the three-jaw chuck 15, avoid empty spraying, and can flush the processing part of the tooth embryo, so as to clean the debris generated in the gear shaping process, and can further avoid the debris from scratching the tooth embryo.

[0056] like Figure 1-Figure 13 As shown, the telescopic assembly includes a swivel 17, a plurality of first plug rods 16 and a plurality of arc grooves 18. The swivel 17 is sleeved on the outside of the filter basket 59 and is rotatably arranged on the side of the processing table 12 away from the three-jaw chuck 15. A plurality of arc grooves 18 are equidistantly arranged on the surface of the swivel 17. Each first plug rod 16 is inserted into an arc groove 18, and the top end of each first plug rod 16 is fixedly connected to a slider 14.

[0057] When the driving assembly is working, it can drive the rotating ring 17 to rotate, and when the rotating ring 17 rotates, it can drive the multiple arc grooves 18 to rotate. Therefore, the first insertion rod 16 can drive the slider 14 to slide inside the slide groove 13, thereby realizing the synchronous movement of multiple three-jaw chucks 15, so that the tooth embryo on the three-jaw chuck 15 can be close to or away from the gear shaping cutter 51, which is convenient for adjusting the position of the tooth embryo during the processing process.

[0058] like Figure 1-Figure 13 As shown, a plurality of guide grooves 22 are equidistantly provided on one side of the processing table 12 close to the swivel 17, each guide groove 22 is located between two adjacent slide grooves 13, and a guide block 23 is slidably provided inside each guide groove 22. Specifically, the length of the guide block 23 is less than the length of the guide groove 22, and the guide block 23 can slide inside the guide groove 22. Each guide block 23 is fixed on one side of the swivel 17 close to the processing table 12, and when the swivel 17 rotates, it can drive the guide block 23 to slide inside the guide groove 22 to play a guiding role. It should be noted that the cross-section of the guide block 23 is T-shaped, and the cross-section of the guide groove 22 matches the guide block 23.

[0059] like Figure 1-Figure 13 As shown, the driving assembly includes a ring gear 19, a gear 20 and a first motor 21. The ring gear 19 is fixedly sleeved on the outer wall of the rotating ring 17. The gear 20 is located on one side of the ring gear 19 and is rotatably arranged on the processing table 12. The gear 20 and the ring gear 19 are meshed with each other. The first motor 21 is installed on the top of the processing table 12. The output end of the first motor 21 is fixedly connected to the gear 20. A side of the processing table 12 is provided with an avoidance groove 24 for avoiding the gear 20.

[0060] Before retracting the tool, first drive the first motor 21 to work, the first motor 21 can drive the gear 20 to rotate. Since the gear 20 and the ring gear 19 are meshed with each other, the gear 20 can drive the ring gear 19 to rotate when it rotates, thereby realizing the rotation of the swivel 17, so that the tooth blanks on the multiple three-jaw chucks 15 can be away from the gear shaping cutter 51, playing a evasive role, so that the gear shaping cutter 51 will not contact the tooth blanks on the three-jaw chuck 15 when retracting the tool, which can effectively prevent the surface of the processed tooth blanks from being scratched during the retracting process and reduce the wear of the gear shaping cutter 51.

[0061] like Figure 1-Figure 13 As shown, each swing assembly includes a pressure rod 33, a connecting rod 36, two L-shaped fixing frames 35, two guide wheels 37, two pull ropes 34 and two coil springs 39;

[0062] The two L-shaped fixing frames 35 are both located on one side of a three-jaw chuck 15 and fixed on the top of the processing table 12. Both ends of the shunt pipe 38 are rotatably set at the ends of the two L-shaped fixing frames 35 through bearings. Two coil springs 39 are respectively sleeved on the two ends of the shunt pipe 38. Both ends of each coil spring 39 are respectively abutted against the shunt pipe 38 and the L-shaped fixing frame 35. In the initial state, each coil spring 39 is in a natural state. The connecting rod 36 is fixed between the middle parts of the two L-shaped fixing frames 35. The two guide wheels 37 are rotatably set on the connecting rod 36. One end of each pull rope 34 is connected to the surface of a nozzle 40. The other end of each nozzle 40 passes through a guide wheel 37 and is fixedly connected to the same pressure rod 33. The guide wheel 37 can guide the pull rope 34.

[0063] When in use, before the cutter is withdrawn, when the three-jaw chuck 15 moves toward the side away from the gear shaping cutter 51, the transmission assembly can be used to drive the pressure rod 33 to rotate downward. At this time, under the pull of the pull rope 34, the shunt tube 38 and the two nozzles 40 can be driven to rotate around the axis of the shunt tube 38. At this time, the two coil springs 39 are deformed. When the three-jaw chuck 15 moves to avoid the gear shaping cutter 51, the nozzles 40 on the shunt tube 38 can be driven to rotate and adjust the angle of the nozzles 40. After the cutter is withdrawn, when the three-jaw chuck 15 is reset, the transmission assembly can be used to drive the pressure rod 33 to reset. At this time, under the action of the two coil springs 39, the shunt tube 38 and the two nozzles 40 can be driven to reset;

[0064] That is, when the three-jaw chuck 15 moves, the nozzle 40 can be driven to rotate. The nozzle 40 can rotate with the movement of the tooth embryo, so that the nozzle 40 can always face the processing part of the tooth embryo on the three-jaw chuck 15, avoiding empty spraying, and can flush the processing part of the tooth embryo, thereby playing a role in cleaning the debris generated in the gear shaping process, which can further prevent the debris from scratching the tooth embryo.

[0065] like Figure 1-Figure 13 As shown, each transmission assembly includes a through hole 25, a moving rod 26, a U-shaped frame 27, a second insertion rod 28, an L-shaped rod 29, a fixed rod 30, a strip groove 32 and two inclined rods 60;

[0066] Each oblique rod 60 is fixed to one side of an L-shaped fixing frame 35, the fixing rod 30 is fixed between the ends of the two oblique rods 60 away from the L-shaped fixing frame 35, the middle part of the L-shaped rod 29 is rotatably arranged on the fixing rod 30 through a bearing, the middle part of the pressure rod 33 is installed at one end of the L-shaped rod 29, and the strip groove 32 is opened at the end of the L-shaped rod 29 away from the pressure rod 33;

[0067] The through hole 25 is provided at one side of the slide groove 13, the moving rod 26 is slidably arranged inside the through hole 25, and one end of the moving rod 26 is fixedly connected to the slider 14, the other end of the moving rod 26 extends out of the through hole 25 and is fixedly connected to the U-shaped frame 27, the second plug rod 28 is inserted into the strip groove 32 and the two ends are fixedly connected to the top ends of the two sides of the second plug rod 28;

[0068] Before retracting the tool, when the slider 14 drives the three-jaw chuck 15 to move away from the gear shaping cutter 51, the slider 14 can drive the moving rod 26 to slide inside the perforation 25, and the moving rod 26 can drive the U-shaped frame 27 to move away from the processing table 12. At this time, the second insertion rod 28 can drive the L-shaped rod 29 to rotate around the axis of the fixed rod 30, thereby driving the pressure rod 33 to rotate downward, which is convenient for the subsequent driving nozzle 40 to rotate with the movement of the tooth embryo.

[0069] like Figure 1-Figure 13 As shown, the conveying assembly includes a conveying pipe 43, an arc-shaped pipe 42, a water pump 44, a water inlet pipe 45 and three hoses 41. The water pump 44 is installed on one side of the base 11. One end of the water inlet pipe 45 is connected to the input end of the water pump 44, and the other end of the water inlet pipe 45 extends into the interior of the storage chamber 46. One end of the conveying pipe 43 is installed at the output end of the water pump 44, and the other end of the conveying pipe 43 is connected to the arc-shaped pipe 42. The arc-shaped pipe 42 is located above a plurality of shunt pipes 38. It should be noted here that two mounting rods 31 are symmetrically fixed on both sides of the lower side of the L-shaped mounting frame 49. The arc-shaped pipe 42 is fixedly mounted on the two mounting rods 31. The arc-shaped pipe 42 can be supported and fixed by the two mounting rods 31. One end of each hose 41 is connected to the arc-shaped pipe 42, and the other end of each hose 41 is connected to a shunt pipe 38. Since the hose 41 is soft in texture, it will not affect the rotation of the shunt pipe 38.

[0070] When the tooth blank is being processed, the water pump 44 is controlled to work. When the water pump 44 is working, the water inside the storage chamber 46 can flow into the interior of the arc tube 42 through the water inlet pipe 45 and the delivery pipe 43, and then the water flows into the interior of the multiple branch pipes 38 through the multiple hoses 41, and is sprayed out through a plurality of nozzles 40. The water stored in the storage chamber 46 can be transported to the multiple branch pipes 38 and sprayed by the nozzles 40 to the processing location of the tooth blank. On the one hand, the debris generated during the processing can be cleaned to prevent the debris from scratching the tooth blank and wearing the gear shaping cutter 51. On the other hand, the cooling effect of the tooth blank and the gear shaping cutter 51 during the processing can be achieved, which is beneficial to increasing the service life of the gear shaping cutter 51.

[0071] like Figure 1-Figure 13As shown, the lifting assembly includes a cylinder 50 and an L-shaped mounting frame 49. The L-shaped mounting frame 49 is fixed to one side of the support column 48. The cylinder 50 is mounted on the L-shaped mounting frame 49. The output end of the cylinder 50 is provided with a push rod through a bearing for rotation. The push rod passes through the L-shaped mounting frame 49 and is fixedly connected to the gear shaping cutter 51.

[0072] When in use, in the initial state, the gear shaping cutter 51 is located above multiple tooth blanks. When the tooth blanks need to be cut, the cylinder 50 is controlled to work. The cylinder 50 can drive the gear shaping cutter 51 to move downward through the push rod. In the process of the gear shaping cutter 51 moving downward, the tooth blanks can be cut and the gear shaping work of the gear can be realized.

[0073] like Figure 1-Figure 13 As shown, the rotating assembly includes a rotating sleeve 52, a limiting groove 53, a limiting block 54, a driving wheel 55, a driven wheel 56, a transmission belt 57 and a second motor 58;

[0074] The rotating sleeve 52 is slidably sleeved on the push rod, and the rotating sleeve 52 is rotatably set on the L-shaped mounting frame 49 through a bearing. A limit groove 53 is provided on the surface of the push rod, and a limit block 54 is slidably set inside the limit groove 53. The limit block 54 is fixedly mounted on the inner wall of the rotating sleeve 52. The driven wheel 56 is fixedly sleeved on the surface of the rotating sleeve 52. The driven wheel 56 is located below the L-shaped mounting frame 49. The driving wheel 55 is located at one side of the driven wheel 56 and is rotatably set on the support column 48. The transmission belt 57 is sleeved on the driving wheel 55 and the driven wheel 56. The second motor 58 is fixedly mounted on the top of the support column 48. The rotating shaft of the driving wheel 55 passes through the support column 48 and is fixedly connected to the output end of the second motor 58.

[0075] When the gear shaping cutter 51 is cutting the tooth blank, that is, when the gear shaping cutter 51 is in contact with the tooth blank, the second motor 58 is controlled to work, and the second motor 58 can drive the driving wheel 55 to rotate. Under the action of the transmission belt 57, the driven wheel 56 can drive the rotating sleeve 52 to rotate on the L-shaped mounting frame 49. At the same time, since the limit block 54 is inserted into the inner part of the limit groove 53, when the rotating sleeve 52 rotates, it can drive the push rod to rotate through the limit groove 53 and the limit block 54, so that the push rod can drive the gear shaping cutter 51 to rotate. When the gear shaping cutter 51 rotates, the rotation of the tooth blank can be realized, which is convenient for cutting the outer ring of the tooth blank.

[0076] At the same time, since the limiting block 54 is slidably connected to the limiting groove 53, the lifting and lowering movement of the pushing rod and the gear shaping cutter 51 will not be affected during the rotation of the pushing rod and the gear shaping cutter 51.

[0077] It should be noted here that when the gear shaping cutter 51 is not in contact with the gear blank, the rotating assembly does not work, that is, the gear shaping cutter 51 does not perform a rotating motion.

[0078] like Figure 1-Figure 13As shown, a plurality of cooling fins 47 for refrigeration are installed inside the storage cavity 46. The plurality of cooling fins 47 are arranged in a ring shape and equidistantly inside the storage cavity 46. The cooling fins 47 can be used to continuously cool the water inside the storage cavity 46, so as to facilitate the subsequent cooling treatment of the gear blank and the gear shaping cutter 51, which is beneficial to improving the service life of the gear shaping cutter 51.

[0079] The specific working process of the present invention is as follows:

[0080] First, the tooth blanks to be processed are placed on a plurality of three-jaw chucks 15, and the tooth blanks are fixed by the three-jaw chucks 15. After the fixing is completed, the water pump 44 is controlled to work. When the water pump 44 is working, the water in the storage chamber 46 can flow into the interior of the arc tube 42 through the water inlet pipe 45 and the delivery pipe 43, and then the water flows into the interior of the plurality of shunt pipes 38 through the plurality of hoses 41, and is sprayed out through a plurality of nozzles 40. The water stored in the storage chamber 46 can be transported to the plurality of shunt pipes 38 and sprayed to the processing location of the tooth blank by the nozzles 40. On the one hand, the debris generated by the processing can be cleaned during cutting to prevent the debris from scratching the tooth blank and wearing the gear shaping cutter 51. On the other hand, the cooling effect of the tooth blank and the gear shaping cutter 51 during the processing can be achieved, which is beneficial to improving the service life of the gear shaping cutter 51.

[0081] Subsequently, the cylinder 50 is controlled to work, and the cylinder 50 can drive the gear shaping cutter 51 to move downward through the push rod. During the process of the gear shaping cutter 51 moving downward, the gear embryo can be cut. At the same time, during the process of the gear shaping cutter 51 cutting the gear embryo, that is, when the gear shaping cutter 51 contacts the gear embryo, the second motor 58 is controlled to work, and the second motor 58 can drive the driving wheel 55 to rotate. Under the action of the transmission belt 57, the driven wheel 56 can drive the rotating sleeve 52 to rotate on the L-shaped mounting frame 49. At the same time, since the limit block 54 is inserted into the inner part of the limit groove 53, when the rotating sleeve 52 rotates, it can drive the push rod to rotate through the limit groove 53 and the limit block 54, so that the push rod can drive the gear shaping cutter 51 to rotate. When the gear shaping cutter 51 rotates, the rotation of the gear embryo can be realized, which is convenient for cutting the outer ring of the gear embryo. Moreover, since the limit block 54 is slidably connected to the limit groove 53, the lifting and lowering movement of the push rod and the gear shaping cutter 51 will not be affected during the rotation of the push rod and the gear shaping cutter 51.

[0082] When the gear shaping cutter 51 moves upward after shaping, that is, before retracting, the first motor 21 is driven to work, and the first motor 21 can drive the gear 20 to rotate. Since the gear 20 and the gear ring 19 are meshed with each other, the gear 20 can drive the gear ring 19 to rotate when it rotates, thereby realizing the rotation of the rotating ring 17. When the rotating ring 17 rotates, it can drive the multiple arc grooves 18 to rotate. Therefore, the first insertion rod 16 can drive the slider 14 to slide inside the slide groove 13, thereby realizing the synchronous movement of multiple three-jaw chucks 15, so that the tooth embryo on the three-jaw chuck 15 can move to the side away from the gear shaping cutter 51, playing an avoidance role, so that the gear shaping cutter 51 will not contact the tooth embryo on the three-jaw chuck 15 when retracting, which can effectively prevent the surface of the processed tooth embryo from being scratched during the retracting process and reduce the wear of the gear shaping cutter 51;

[0083] During this process, when the slider 14 drives the three-jaw chuck 15 to move in a direction away from the gear shaping cutter 51, the slider 14 can drive the moving rod 26 to slide inside the perforation 25, and the moving rod 26 can drive the U-shaped frame 27 to move in a direction away from the processing table 12. At this time, the second insertion rod 28 can drive the L-shaped rod 29 to rotate around the axis of the fixed rod 30, thereby driving the pressure rod 33 to rotate downward. At this time, under the pulling of the pull rope 34, the shunt pipe 38 and the two nozzles 40 can be driven to rotate around the axis of the shunt pipe 38. At this time, both the coil springs 39 are deformed, that is, the nozzle 40 can be driven to rotate while the three-jaw chuck 15 moves. The nozzle 40 can rotate with the movement of the tooth embryo, so that the nozzle 40 can always face the processing part of the tooth embryo on the three-jaw chuck 15, avoid empty spraying, and can rinse the processing part of the tooth embryo, so as to clean the debris generated in the gear shaping process, and can further avoid the debris from scratching the tooth embryo;

[0084] Finally, the gear shaping cutter 51 is driven to move upward by the lifting assembly, and then the first motor 21 drives the gear 20 to flip, so that the rotating ring 17 can be flipped, and then the multiple three-jaw chucks 15 can be reset to facilitate the next cutting work;

[0085] At the same time, when the slider 14 is reset, the moving rod 26 can be driven to reset, so that the nozzle 40 can be reset under the action of the coil spring 39, so that when the three-jaw chuck 15 drives the tooth embryo to reset, the nozzle 40 can rotate and reset with the movement of the tooth embryo, so that when the gear shaping cutter 51 cuts the tooth embryo, water can be sprayed on the tooth embryo and the cutting part of the gear shaping cutter 51 to cool down and clean up debris;

[0086] The water can then flow into the interior of the filter basket 59 with the debris, and the filter basket 59 can be used to filter the debris so that the debris can remain in the filter basket 59 for collection, which is convenient for subsequent recycling. At the same time, the filtered water can flow into the storage chamber 46 again, which can achieve the recycling of water and is beneficial to saving water resources.

[0087] The beneficial effects of the present invention are specifically embodied in that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
