Utility Model Content
[0003] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by implementing the utility model. The purpose and other advantages of the utility model can be realized and obtained through the structures specifically pointed out in the description and other drawings of the description.
[0004] The utility model aims to overcome the above-mentioned shortcomings and provide a device for grinding the inner ring of a gear blank.
[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is: a gear blank inner ring grinding device, comprising a frame and a grinding mechanism, the frame is rotatably connected to a turntable, the grinding mechanism is slidably connected to the turntable, the turntable is provided with a feeding mechanism for driving the grinding mechanism to slide, the turntable is provided with a guiding mechanism for guiding the grinding mechanism to slide along the radius of the turntable, the turntable is rotated by the driving of the driving mechanism, the frame is provided with a plurality of clamping mechanisms for fixing the gear blank in a concentric position with the turntable, and the plurality of clamping mechanisms are arranged around the center of the turntable.
[0006] By adopting the above technical scheme, the driving mechanism can drive the turntable to rotate, so that the grinding mechanism arranged on the turntable can rotate along the inner ring of the gear blank to realize the grinding of the inner ring, and at the same time, by utilizing the cooperation of the guiding mechanism and the feeding mechanism, the grinding mechanism can slide along the radius of the turntable, so that the grinding mechanism can adjust the position according to the size of the inner ring of the gear, and control the feed amount of grinding at the same time. In this way, when clamping the gear blank, the grinding mechanism can be moved to the center of the turntable first, and then the inner ring of the gear blank can be passed through the grinding mechanism, so that the grinding mechanism does not need to be lifted and lowered, which is convenient for processing and clamping. The clamping mechanism can fix the gear blank above the center of the turntable, so that the center of the gear blank overlaps with the center of the turntable, so that the grinding mechanism can always be on the inner ring of the tooth surface blank when the turntable rotates.
[0007] Preferably, the guiding mechanism comprises a guide rail and a slide, the guide rail is fixedly connected to the turntable, and the guide rail is located on the radius of the turntable, the slide is slidably connected to the guide rail, and the grinding mechanism is fixedly connected to the slide. The guide rail of the utility model is a square bar with blocks at both ends, and the bottom of the slide has a groove and is embedded in the guide rail. In this way, the sliding direction of the slide is guided, and the grinding mechanism is guided by fixing the grinding mechanism on the slide. At the same time, the block at the end of the guide rail can limit the sliding range of the slide, so that the grinding mechanism can be exactly at the center of the turntable when it reaches the end of the guide rail, thereby facilitating the control of the feed amount. At the same time, when clamping the gear blank, the grinding mechanism can also be moved to the center of the turntable first, so that the grinding mechanism can easily pass through the center of the gear blank.
[0008] Preferably, the feeding mechanism is a cylinder 1, the cylinder 1 is fixedly connected to the turntable, and the output rod of the cylinder 1 is fixedly connected to the slide. The utility model utilizes the telescopic output rod of the cylinder 1 to push the slide to slide, thereby realizing the driving of the grinding mechanism.
[0009] Preferably, the driving mechanism comprises a gear ring, a gear and a motor, the gear ring is fixedly connected to the turntable, the motor is fixedly connected to the frame, the gear is fixed to the output shaft of the motor, and the gear and the gear ring are meshed. The utility model utilizes a motor to drive the gear to rotate, and the gear ring is driven to rotate by the meshing of the gear and the gear ring, thereby realizing the driving of the turntable.
[0010] Preferably, the clamping mechanism includes a clamping plate, a second cylinder and a supporting mechanism for holding the gear blank, the second cylinder is fixedly connected to the frame, the clamping plate is fixedly connected to the output rod of the second cylinder, and each clamping plate is provided with a clamping mechanism for limiting the rotation of the gear blank. The second cylinders of the utility model are all arranged along the radius of the turntable, and the output rod of the second cylinder just points to the center of the turntable when extended. When clamping the gear blank, the output rods of several second cylinders apply thrust to the outer circle of the gear blank through the clamping plate, so that the gear moves to the top of the center of the turntable and is fixed under the thrust of several second cylinders, and the supporting mechanism supports the bottom of the gear blank to prevent it from falling, and the clamping mechanism is used to prevent the gear blank from rotating under the action of the cutting force.
[0011] Preferably, the clamping mechanism includes two clamping plates, both of which are rotatably connected to the clamping plate, and the clamping plate is slidably connected to two push rods, which are respectively in contact with the two clamping plates, and an elastic member 1 is provided between the two push rods and the clamping plate. In the utility model, when the clamping plate approaches the gear blank, the two clamping plates will press against the outer circle of the gear blank, and as the clamping plate continues to approach the gear blank, the clamping plate will rotate under the action of the cylindrical surface of the gear blank, and when the clamping plate rotates, it will push the push rod to slide in the direction of overcoming the elastic force of the elastic member 1, so that the elastic member 1 generates an elastic force, which pushes the push rod to apply a thrust to the clamping plate, so that the clamping plate is pressed against the cylindrical surface of the gear blank. Through this clamping force, a certain friction force is generated between the clamping plate and the gear blank, thereby limiting the rotation of the gear blank.
[0012] Preferably, the support mechanism includes a support plate, the support plate is slidably connected to the frame, the support plate is fixedly connected with a connecting plate, the connecting plate is penetrated by the output rod of the second cylinder, and the connecting plate is slidably connected to the output rod of the second cylinder, an elastic member 2 is provided between the connecting plate and the clamping plate, and the frame is provided with a limiting mechanism for limiting the sliding of the support plate.

When the gear blank is clamped, the clamping plate is first driven forward by the second cylinder, and the clamping plate drives the support plate to move synchronously through the second elastic member and the connecting plate, so that the support plate first reaches a position that can just hold the gear blank, and then the inner ring of the gear blank is passed through the grinding mechanism and placed on the support plate, and then the second cylinder is started again, so that the second cylinder drives the clamping plate and the clamping mechanism to complete the positioning and fixation of the gear blank. After clamping is completed, the limit mechanism can limit the return of the support plate so that it will not retreat under the drive of the clamping plate. In this way, in the process of loosening the gear blank, the clamping plate will move by compressing the elastic member 2, so that the gear blank can be loosened normally, and the support plate will remain in place under the action of the limit mechanism, thereby avoiding the gear blank from falling off when loosening. At the same time, after the elastic member 2 is fully compressed, the clamping plate will also be restricted by the support plate to stop retreating, thereby limiting the travel range of the clamping plate and reducing the time consumed in clamping.
[0013] Preferably, the limiting mechanism comprises a screw and a push plate, the push plate is fixedly connected to the support plate, the screw is internally connected to the frame thread, and the push plate and the screw abut against each other. The utility model utilizes the self-locking property of the screw thread connection so that when the support plate drives the push plate to slide backward, it cannot slide due to the pressure of the screw.
[0014] In summary, the beneficial effects of the utility model are:
[0015] 1. The driving mechanism can drive the turntable to rotate, so that the grinding mechanism arranged on the turntable can rotate along the inner ring of the gear blank to realize the grinding of the inner ring.

[0030] like Figure 1-2 As shown, a gear blank inner ring grinding device includes a frame 1 and a grinding mechanism 2, the frame 1 is rotatably connected to a turntable 3, the grinding mechanism 2 is slidably connected to the turntable 3, the turntable 3 is provided with a feeding mechanism for driving the grinding mechanism 2 to slide, the turntable 3 is provided with a guiding mechanism for guiding the grinding mechanism 2 to slide along the radius of the turntable 3, the turntable 3 is driven to rotate by the driving mechanism, the frame 1 is provided with a plurality of clamping mechanisms for fixing the gear 8 blank at a position concentric with the turntable 3, and the plurality of clamping mechanisms are arranged around the center of the turntable 3.
[0031] By adopting the above technical scheme, the driving mechanism can drive the turntable 3 to rotate, so that the grinding mechanism 2 set on the turntable 3 can rotate along the inner ring of the gear 8 blank to achieve the grinding of the inner ring. At the same time, by using the cooperation of the guiding mechanism and the feeding mechanism, the grinding mechanism 2 can slide along the radius of the turntable 3, so that the grinding mechanism 2 can adjust the position according to the size of the inner ring of the gear 8, and control the grinding feed amount at the same time. In this way, when clamping the gear 8 blank, the grinding mechanism 2 can be moved to the center of the turntable 3 first, and then the inner ring of the gear 8 blank can be passed through the grinding mechanism 2, so that the grinding mechanism 2 does not need to be lifted or lowered, which is convenient for processing and clamping. The clamping mechanism can fix the gear 8 blank above the center of the turntable 3, so that the center of the gear 8 blank overlaps with the center of the turntable 3, so that the grinding mechanism 2 can always be on the inner ring of the tooth surface blank when the turntable 3 rotates.
[0032] The guide mechanism includes a guide rail 4 and a slide 5. The guide rail 4 is fixedly connected to the turntable 3 and is located on the radius of the turntable 3. The slide is slidably connected to the guide rail 4, and the grinding mechanism 2 is fixedly connected to the slide 5. The guide rail 4 is a square bar with blocks at both ends. The slide 5 has a groove at the bottom and is embedded in the guide rail 4. In this way, the sliding direction of the slide 5 is guided. The grinding mechanism 2 is guided by fixing it on the slide 5. At the same time, the block at the end of the guide rail 4 can limit the sliding range of the slide 5, so that the grinding mechanism 2 can be exactly at the center of the turntable 3 when it reaches the end of the guide rail 4, so as to facilitate the control of the feed amount. At the same time, when clamping the gear 8 blank, the grinding mechanism 2 can also be moved to the center of the turntable 3 first, so that the grinding mechanism 2 can easily pass through the center of the gear 8 blank.
[0033] The feeding mechanism is a cylinder 6, which is fixedly connected to the turntable 3, and the output rod of the cylinder 6 is fixedly connected to the slide 5. The slide 5 is pushed to slide by the extension and contraction of the output rod of the cylinder 6, thereby driving the grinding mechanism 2.
[0034] The driving mechanism includes a ring gear 7, a gear 8 and a motor 9. The ring gear 7 is fixedly connected to the turntable 3, the motor 9 is fixedly connected to the frame 1, the gear 8 is fixed to the output shaft of the motor 9, and the gear 8 is meshed with the ring gear 7. The motor 9 drives the gear 8 to rotate, and the meshing of the gear 8 and the ring gear 7 drives the ring gear 7 to rotate, thereby driving the turntable 3.
[0035] The clamping mechanism includes a clamping plate 10, a cylinder 11 and a support mechanism for holding the gear 8 blank. The cylinder 11 is fixedly connected to the frame 1, and the clamping plate 10 is fixedly connected to the output rod of the cylinder 11. Each clamping plate 10 is provided with a clamping mechanism for limiting the rotation of the gear 8 blank. The cylinders 11 are arranged along the radius of the turntable 3. When the output rod of the cylinder 11 is extended, it just points to the center of the turntable 3. When the gear 8 blank is clamped, the output rods of several cylinders 11 apply thrust to the outer circle of the gear 8 blank through the clamping plate 10, so that the gear 8 moves to the top of the center of the turntable 3 and is fixed under the thrust of several cylinders 11. The support mechanism holds the bottom of the gear 8 blank to prevent it from falling. The clamping mechanism prevents the gear 8 blank from rotating under the action of the cutting force.
[0036] The clamping mechanism includes two clamping plates 12, both of which are rotatably connected to the clamping plate 10. The clamping plate 10 is slidably connected to two push rods 13, which are respectively in contact with the two clamping plates 12, and an elastic member 14 is provided between the two push rods 13 and the clamping plate. When the clamping plate 10 approaches the gear 8 blank, the two clamping plates 12 will press against the outer circle of the gear 8 blank. As the clamping plate 10 continues to approach the gear 8 blank, the clamping plate 12 will rotate under the action of the cylindrical surface of the gear 8 blank. When the clamping plate 12 rotates, it will push the push rod 13 to slide in the direction of overcoming the elastic force of the elastic member 14, so that the elastic member 14 generates an elastic force, pushing the push rod 13 to apply a thrust to the clamping plate 12, so that the clamping plate 12 is pressed against the cylindrical surface of the gear 8 blank. Through this clamping force, a certain friction force is generated between the clamping plate 12 and the gear 8 blank, thereby limiting the rotation of the gear 8 blank.
[0037] The supporting mechanism includes a support plate 15, which is slidably connected to the frame 1. The support plate 15 is fixedly connected to a connecting plate 16, which is penetrated by the output rod of the cylinder 11, and the connecting plate 16 is slidably connected to the output rod of the cylinder 11. An elastic member 17 is arranged between the connecting plate 16 and the clamping plate 10, and the frame 1 is provided with a limiting mechanism for limiting the sliding of the support plate 15. The support plate 15 is located below the clamping plate 10, and the support plate 15 is linked with the clamping plate 10 through the connecting plate 16 and the second elastic member 17. When the gear 8 blank is clamped, the clamping plate 10 is first driven forward by the second cylinder 11, and the clamping plate 10 drives the support plate 15 to move synchronously through the second elastic member 17 and the connecting plate 16, so that the support plate 15 first reaches a position where it can just hold the gear 8 blank, and then the inner ring of the gear 8 blank passes through the grinding mechanism 2 and is placed on the support plate 15, and then the second cylinder 11 is started, so that the second cylinder 11 drives the clamping plate 10 and the clamping mechanism to complete the grinding of the gear 8 blank. The positioning and fixation, after the clamping is completed, the return of the support plate 15 can be limited by the limit mechanism, so that it will not retreat under the drive of the clamping plate 10. In this way, in the process of loosening the gear 8 blank, the clamping plate 10 will move by compressing the elastic member 2 17, so that the gear 8 blank can be normally loosened, and the support plate 15 will remain in place under the action of the limit mechanism, thereby avoiding the gear 8 blank from falling off when loosening. At the same time, after the elastic member 2 17 is fully compressed, the clamping plate 10 will also be restricted by the support plate 15 to stop retreating, thereby limiting the travel range of the clamping plate 10 and reducing the time consumed in clamping.
[0038] The limiting mechanism includes a screw 18 and a push plate 19. The push plate 19 is fixedly connected to the support plate 15. The screw 18 is internally connected to the frame 1 through a thread. The push plate 19 and the screw 18 abut against each other. By utilizing the self-locking property of the screw 18 thread connection, when the support plate 15 drives the push plate 19 to slide backward, the support plate 15 cannot slide due to the pressure of the screw 18.
[0039] It should be noted that many specific details are set forth in the above description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.
