Description

Technical Field

[0001] The present invention relates to the technical field of gear processing equipment, and specifically to a precise chamfering device for gear production and processing. Background Art

[0002] ‌A gear is a mechanical transmission element that has the functions of transmitting power and rotational speed. In order to reduce the noise during gear meshing, improve the meshing accuracy, extend the service life of the gear, and reduce the stress concentration during heat treatment, etc., it is necessary to use a chamfering device to perform chamfering operations on the gear.

[0003] In the prior art, when chamfering a gear, generally, one side of the gear is chamfered first. After this side chamfering is completed, the gear is flipped, and then the other side is chamfered. This method has the problem of low chamfering efficiency. In response to this problem, a Chinese patent with the publication number CN216096808U discloses a gear chamfering device. Two chamfering blades are installed vertically on one side of the gear, and the two chamfering blades are used to simultaneously grind the two sides of the gear. Although this method can improve the grinding efficiency, it has the following deficiencies: 1. When chamfering, the debris generated by the upper grinding blade during chamfering is likely to fall on the lower grinding blade, resulting in the surface of the lower grinding blade being easily adhered with debris, which will affect the chamfering accuracy and chamfering effect of the lower grinding blade on the gear; 2. After chamfering, there are burrs at the chamfered position, and the device cannot simultaneously polish the chamfered position, and manual polishing is required later, which is time-consuming and laborious; In response to the above problems, a precise chamfering device for gear production and processing is now provided.

Specific embodiments

[0031] The principles and features of the present invention will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0032] The present invention provides the following preferred embodiments: Embodiment 1, as Figures 1 - 10 shown, a precise chamfering device for gear production and processing, including a bottom plate 11, and further including a chamfering mechanism, a cleaning mechanism, a polishing mechanism and a positioning mechanism; The positioning mechanism is fixedly installed at the top of the bottom plate 11. The positioning mechanism includes a vertical plate 12, a chuck 13 and a first motor 14. The positioning mechanism is used to install the gear to be processed and can also rotate the gear to be processed, so as to facilitate the chamfering of the teeth at different positions of the gear to be processed by the chamfering wheel 18; The chamfering mechanism includes a chamfering table 15, a moving component, two rotating plates 16, two chamfering wheels 18 and two driving components. The chamfering table 15 is located on one side of the positioning component and is fixedly installed at the top of the bottom plate 11. The two rotating plates 16 are symmetrically arranged above the chamfering table 15. The middle of each rotating plate 16 is rotatably arranged on the chamfering table 15. Each chamfering wheel 18 is installed at one end of a rotating plate 16. The moving component is located between the chamfering table 15 and the two rotating plates 16. Each driving component is installed between a rotating plate 16 and a chamfering wheel 18; During use, the chamfering wheel 18 can rotate on the rotating plate 16 through the driving component, and the two rotating plates 16 can swing by using the moving component, so that the chamfering wheel 18 can rotate to one side of the gear to be processed under the action of the rotating plate 16, and chamfering treatment of the gear to be processed can be realized. When chamfering of one tooth is completed, the moving component drives the rotating plate 16 to swing in the reverse direction, so that the two chamfering wheels 18 can move away from the gear to be processed. Subsequently, the first motor 14 is used to rotate the gear, so that the next tooth on the gear to be processed can be rotated to one side of the chamfering wheel 18, so as to facilitate the chamfering wheel 18 to chamfer the next tooth. And so on, chamfering operation of the entire gear to be processed can be realized; The cleaning mechanism includes two cleaning brushes 49, two swinging components, two first transmission components and two pulling components. The two cleaning brushes 49 are symmetrically arranged above the bottom plate 11, and the two cleaning brushes 49 are respectively located on both sides of the bottom end of the gear to be processed. Each swinging component is installed on one side of a cleaning brush 49 close to the chamfering mechanism, each first transmission component is installed on one side of a swinging component, and each pulling component is located between a swinging component and a rotating plate 16; When a rotating plate 16 swings towards the direction close to the gear to be processed, so that the chamfering wheel 18 can chamfer the gear to be processed, the rotating plate 16 can drive the pulling component to work. Under the action of the first transmission component, the swinging component can realize the swinging of the cleaning brush 49, that is, when the chamfering wheel 18 moves to one side of the gear to be processed to chamfer the gear to be processed, the swinging plate 47 can swing towards the direction close to the gear to be processed, and clean the chamfered part of the gear after processing, and sweep away the debris attached to its surface; It should be noted here that during actual use, a collection box can be arranged at the bottom end of the gear to be processed to collect the swept debris, which is convenient for subsequent recycling; At the same time, when the cleaning brush 49 swings, under the action of centrifugal force, the swept debris also separates from the cleaning brush 49 under the action of centrifugal force, reducing the possibility of debris adhering to the cleaning brush 49; When chamfering of one tooth is completed and the rotating plate 16 swings in the reverse direction, it can drive the cleaning brush 49 to reset, which is convenient for the next cleaning; The polishing mechanism includes two polishing heads 55, two rotating components and two second transmission components. Each polishing head 55 is located on the side of the positioning mechanism away from the rotating plate 16. The two rotating components are both installed on the bottom plate 11. The rotating component can realize the rotation of the polishing head 55, so as to facilitate polishing treatment of the chamfered part of the gear. Each polishing head 55 is located on one side of a rotating component, and each second transmission component is located between a rotating component and a swinging component; When the cleaning brush 49 swings towards the direction of the gear to be processed, the swinging of the polishing head 55 can be realized through the second transmission component, so that the polishing head 55 can swing towards the direction of the gear to be processed synchronously, realizing the polishing of the chamfer, reducing the appearance of burrs, being beneficial to improving the chamfer quality, and eliminating the need for manual polishing. When the cleaning brush 49 swings in the reverse direction, it can drive the polishing head 55 to swing away from the gear to be processed under the action of the second transmission component, with high synchronism.

[0033] As Figures 1 - 10 shown, the moving component includes a second motor 27, a rotating rod 25, two articulated rods 26, two sliding plates 24, two first strip-shaped grooves 22 and two first inserting rods 23. The two sliding plates 24 are symmetrically and slidably arranged on both sides above the chamfering table 15. Each first inserting rod 23 is fixedly installed on a sliding plate 24. Each first strip-shaped groove 22 is opened on the surface of one end of a rotating plate 16 away from the chamfering wheel 18. The other end of each first inserting rod 23 is inserted into the interior of a first strip-shaped groove 22. The middle of the rotating rod 25 is rotatably arranged on the chamfering table 15. The second motor 27 is fixedly installed at the bottom end of the chamfering table 15. The output end of the second motor 27 is fixedly connected to the rotating rod 25. Specifically, a rotating shaft is fixedly installed in the middle of the rotating rod 25. The rotating shaft is rotatably arranged on the chamfering table 15. The output end of the second motor 27 is fixedly connected to the bottom end of the rotating shaft. Thus, when the second motor 27 works, it can drive the rotating rod 25 to rotate. One end of each articulated rod 26 is articulated with the end of the sliding plate 24, and the other end of each articulated rod 26 is articulated with the end of the rotating rod 25. When chamfering the gear to be processed is required, the controller controls the second motor 27 to work. The second motor 27 drives the rotating rod 25 to rotate. Under the action of the two articulated rods 26, it can drive the two sliding plates 24 to move away from each other. Thus, under the action of the first inserting rods 23, it can drive the rotating plate 16 to swing, so that the chamfering wheel 18 at one end of the rotating plate 16 can move towards the gear to be processed, facilitating the chamfering of the gear to be processed.

[0034] As Figures 1 - 10 shown, each driving component includes a chamfering motor 17, a first pulley 19, a second pulley 20 and a transmission belt 21. The first pulley 19 is rotatably arranged on the side of the rotating plate 16 away from the chamfering wheel 18. The first pulley 19 and the chamfering wheel 18 are coaxially and fixedly connected, that is, when the first pulley 19 rotates, it can drive the chamfering wheel 18 to rotate synchronously. The second pulley 20 is located on one side of the first pulley 19 and rotates below the rotating plate 16. The transmission belt 21 is sleeved on the first pulley 19 and the second pulley 20. The chamfering motor 17 is installed at the top end of the rotating plate 16. The output end of the chamfering motor 17 is fixedly connected to the second pulley 20. When it is necessary to rotate the chamfering wheel 18, the controller controls the chamfering motor 17 to work. The chamfering motor 17 can drive the second pulley 20 to rotate. Under the action of the transmission belt 21, when the second pulley 20 rotates, it can drive the first pulley 19 to rotate, so as to realize the rotation of the chamfering wheel 18, and thus realize the chamfering treatment of the teeth.

[0035] As Figures 1 - 10 shown, each pulling component includes a vertical rod 29, a pulling rope 30, a guide pulley 31, a gear 34, a connecting plate 40, a sliding rod 41, a spring 42 and a limiting plate 43. One end of the vertical rod 29 is fixedly connected to the surface of one of the rotating plates 16. The gear 34 is slidably arranged on the bottom plate 11. The guide pulley 31 is located on one side of the gear 34 and is rotatably arranged on the bottom plate 11. One end of the pulling rope 30 is connected to the gear 34. The other end of the pulling rope 30 bypasses the guide pulley 31 and is connected to the bottom end of the vertical rod 29. The guide pulley 31 is used to guide the pulling rope 30. The limiting plate 43 is located on one side of the gear 34 and is fixed on the bottom plate 11. The connecting plate 40 is fixedly installed on one side of the gear 34. The sliding rod 41 is slidably arranged on the limiting plate 43. One end of the sliding rod 41 is fixedly connected to the connecting plate 40. The spring 42 is sleeved on the sliding rod 41. The two ends of the spring 42 are respectively connected to the limiting plate 43 and the connecting plate 40; In the initial state, the spring 42 is in a natural state. When the rotating plate 16 moves towards the direction close to the gear to be processed, the rotating plate 16 drives the vertical rod 29 to move. The vertical rod 29 drives the gear 34 to move towards the direction close to the guide pulley 31 through the pulling rope 30. The gear 34 drives the sliding rod 41 to slide on the limiting plate 43 through the connecting plate 40, and the spring 42 is stretched; When the rotating plate 16 moves towards the direction away from the gear to be processed, the spring 42 can drive the gear 34 to move in the reverse direction.

[0036] As Figures 1 - 10 shown, each second transmission component includes a rack 33, a mounting plate 35, a first sprocket 36, a second sprocket 37, a chain 38 and a fixing plate 39. The mounting plate 35 and the fixing plate 39 are both fixed on the bottom plate 11. The rack 33 is rotatably arranged on one side of the mounting plate 35. The rack 33 meshes with the gear 34. The first sprocket 36 is located at the end of the mounting plate 35 away from the rack 33. The first sprocket 36 and the rack 33 are coaxially fixedly connected. The second sprocket 37 is rotatably arranged on one side of the fixing plate 39. The chain 38 is sleeved on the first sprocket 36 and the second sprocket 37; When the gear 34 moves towards the direction close to the guide pulley 31, the gear 34 can drive the rack 33 to rotate. The rack 33 drives the first sprocket 36 to rotate. Under the action of the chain 38, the second sprocket 37 can be driven to rotate.

[0037] As Figures 1 - 10As shown in the figure, each swinging component includes a turntable 44, a second insertion rod 45, a second strip-shaped groove 46, a swinging plate 47, a mounting seat 48 and a rotating shaft 50. The mounting seat 48 is fixedly installed on the bottom plate 11. The cleaning brush 49 is installed on one side of the swinging plate 47. The rotating shaft 50 is fixed at one end of the swinging plate 47 away from the cleaning brush 49. The rotating shaft 50 is rotatably arranged on the mounting seat 48. The second strip-shaped groove 46 is opened on one side of the swinging plate 47. The turntable 44 is located on the side of the fixed plate 39 away from the second sprocket 37. The turntable 44 is coaxially and fixedly connected to the second sprocket 37. One end of the second insertion rod 45 is inserted into the inside of the second strip-shaped groove 46, and the other end of the second insertion rod 45 is fixedly connected to the turntable 44; When the second sprocket 37 rotates, it can drive the turntable 44 to rotate. Under the action of the second insertion rod 45, it can drive the swinging plate 47 to swing around the axis of the rotating shaft 50 in the direction close to the gear to be processed, so that the cleaning brush 49 can swing synchronously towards the gear to be processed, realizing the cleaning of the gear to be processed; When the rotating plate 16 moves in the direction away from the gear to be processed, under the action of the spring 42, it can drive the gear 34 to move in the reverse direction. When the gear 34 moves in the reverse direction, it can drive the turntable 44 to rotate in the reverse direction, so that the cleaning brush 49 can swing in the reverse direction to the initial state, that is, when the chamfering wheel 18 approaches the gear to be processed, the cleaning brush 49 can swing synchronously towards the gear to be processed, realizing the primary cleaning of the chamfering area.

[0038] As Figures 1 - 10 shown in the figure, each rotating component includes a polishing table 53, an L-shaped plate 54 and a polishing motor 56. The polishing table 53 is located on the side of the mounting seat 48 away from the chamfering table 15. The polishing table 53 is fixedly installed on the bottom plate 11. The L-shaped plate 54 is rotatably arranged on the top of the polishing table 53. The polishing head 55 is installed on one side of the L-shaped plate 54. The polishing motor 56 is fixedly arranged on the L-shaped plate 54. The output end of the polishing motor 56 is fixedly connected to the polishing head 55; The controller drives the polishing motor 56 to work, and the polishing motor 56 can drive the polishing head 55 to rotate, so as to facilitate the subsequent polishing of the chamfered part of the gear.

[0039] As Figures 1 - 10 shown in the figure, each second transmission component includes a first bevel gear 51, a second bevel gear 52 and a drive shaft 57. The drive shaft 57 is rotatably arranged between the bottom plate 11 and one of the polishing tables 53. The top end of the drive shaft 57 is fixedly connected to one of the L-shaped plates 54, that is, when the drive shaft 57 rotates, it can drive the L-shaped plate 54 to rotate on the polishing table 53, so as to realize the rotation of the polishing head 55. The second bevel gear 52 is fixedly installed on the bottom surface of the bottom end of the drive shaft 57. The first bevel gear 51 is fixed at one end of the rotating shaft 50 away from the turntable 44. The first bevel gear 51 and the second bevel gear 52 are meshed with each other; When the cleaning brush 49 swings towards the direction of the gear to be processed, the rotating shaft 50 can drive the first bevel gear 51 to rotate. Since the first bevel gear 51 meshes with the second bevel gear 52, when the first bevel gear 51 rotates, it can drive the second bevel gear 52 to rotate. Thus, under the action of the drive shaft 57, the L-shaped plate 54 can be driven to swing, so that the polishing head 55 can swing towards the gear to be processed, realizing the polishing of the chamfered part of the gear. Similarly, when the cleaning brush 49 swings away from the direction of the gear to be processed, the polishing head 55 can move away from the gear to be processed synchronously. During use, the chamfering wheel 18 can be rotated on the rotating plate 16 through the drive assembly, and the two rotating plates 16 can be swung by the moving assembly. Thus, the chamfering wheel 18 can be rotated to one side of the gear to be processed under the action of the rotating plate 16, and the chamfering process of the gear to be processed can be realized. At the same time, the cleaning brush 49 performs a cleaning on the chamfered part once, and the polishing head 55 performs a polishing on the chamfered part once. After the chamfering of one tooth is completed, the rotating plate 16 is driven to swing in the reverse direction by the moving assembly, so that the two chamfering wheels 18 can move away from the gear to be processed. At the same time, the swing plate 47 and the polishing head 55 can both move away from the gear to be processed. Subsequently, the first motor 14 is used to rotate the gear, so that the next tooth on the gear to be processed can be rotated to one side of the chamfering wheel 18, facilitating the chamfering process of the next tooth by the chamfering wheel 18. By analogy, the chamfering operation of the entire gear to be processed can be realized.

[0040] As Figures 1 - 10 shown, the vertical plate 12 is fixedly installed at the top of the bottom plate 11, the chuck 13 is rotatably arranged on one side of the vertical plate 12, the first motor 14 is fixed on the side of the vertical plate 12 away from the chuck 13, and the output end of the first motor 14 is fixedly connected to the chuck 13. During use, first, the gear to be processed is installed on one side of the vertical plate 12 through the chuck 13. When it is necessary to rotate the gear to be processed, the controller controls the first motor 14 to work, and the first motor 14 can drive the gear to be processed to rotate through the chuck 13, facilitating the chamfering process of the teeth at different positions of the gear to be processed. It should be noted here that the chuck 13 is a prior art and will not be specifically described here.

[0041] As Figures 1 - 10 shown, two first guide rails 28 are symmetrically fixed on both sides of the top of the chamfering table 15. Each sliding plate 24 is slidably arranged inside one first guide rail 28, which can play a guiding and supporting role for the sliding plate 24. A second guide rail 32 is provided below each gear 34. Each second guide rail 32 is fixed on the bottom plate 11. Each gear 34 is slidably arranged inside one second guide rail 32. The second guide rail 32 can play a guiding and supporting role for the gear 34, ensuring the stability of the equipment.

[0042] The specific working process of the present invention is as follows: In use, first, the gear to be processed is installed on one side of the vertical plate 12 through the chuck 13. The controller controls the chamfering motor 17 to work. The chamfering motor 17 can drive the second pulley 20 to rotate. Under the action of the transmission belt 21, when the second pulley 20 rotates, it can drive the first pulley 19 to rotate, so as to realize the rotation of the chamfering wheel 18. The controller controls the polishing motor 56 to work. The polishing motor 56 can drive the polishing head 55 to rotate. The controller controls the second motor 27 to work. The second motor 27 drives the rotating rod 25 to rotate. Under the action of the two hinge rods 26, it can drive the two sliding plates 24 to move away from each other. Thus, under the action of the first plug rod 23, it can drive the rotating plate 16 to swing, so that the chamfering wheel 18 at one end of the rotating plate 16 can move towards the gear to be processed, so as to chamfer the gear to be processed; When the rotating plate 16 moves towards the gear to be processed, the rotating plate 16 drives the vertical rod 29 to move. The vertical rod 29 drives the gear 34 to move towards the guide wheel 31 through the pulling rope 30. The gear 34 drives the sliding rod 41 to slide on the limiting plate 43 through the connecting plate 40, and the spring 42 is stretched. When the gear 34 moves towards the guide wheel 31, the gear 34 can drive the rack 33 to rotate. The rack 33 drives the first sprocket 36 to rotate. Under the action of the chain 38, it can drive the second sprocket 37 to rotate. When the second sprocket 37 rotates, it can drive the turntable 44 to rotate. Under the action of the second plug rod 45, it can drive the swing plate 47 to swing around the axis of the rotating shaft 50 towards the gear to be processed, so that the cleaning brush 49 can swing towards the gear to be processed synchronously, realizing the cleaning of the gear to be processed. When the cleaning brush 49 swings towards the gear to be processed, the rotating shaft 50 can drive the first bevel gear 51 to rotate. Since the first bevel gear 51 and the second bevel gear 52 are meshed with each other, when the first bevel gear 51 rotates, it can drive the second bevel gear 52 to rotate. Thus, under the action of the driving shaft 57, it can drive the L-shaped plate 54 to swing, so that the polishing head 55 can swing towards the gear to be processed, realizing the polishing of the chamfered part of the gear; When chamfering of one tooth is completed, the moving component drives the rotating plate 16 to swing in the reverse direction, so that the two chamfering wheels 18 can move away from the gear to be processed. When the rotating plate 16 moves away from the gear to be processed, under the action of the spring 42, it can drive the gear 34 to move in the reverse direction. When the gear 34 moves in the reverse direction, it can drive the turntable 44 to rotate in the reverse direction, so that the cleaning brush 49 can swing in the reverse direction to the initial state. When the cleaning brush 49 swings away from the gear to be processed, the polishing head 55 can move away from the gear to be processed synchronously; That is, when the chamfering wheel 18 chamfers the gear to be processed, the cleaning brush 49 performs a cleaning on the chamfering position, and the polishing head 55 performs a polishing on the chamfering position. After the chamfering of one tooth is completed, the rotating plate 16 is driven to swing in the reverse direction by the moving assembly, so that the two chamfering wheels 18 can move away from the gear to be processed. At the same time, the swing plate 47 and the polishing head 55 can also move away from the gear to be processed. Subsequently, the controller controls the first motor 14 to work, and the first motor 14 can drive the gear to be processed to rotate through the chuck 13, so that the next tooth on the gear to be processed can be rotated to one side of the chamfering wheel 18, facilitating the chamfering process of the next tooth by the chamfering wheel 18. By analogy, the chamfering operation of the entire gear to be processed can be realized.
