Description

Technical Field

[0001] The present application relates to the field of gear manufacturing, and in particular to a gear deburring grinding device. Background Art

[0002] Gears are mechanical components with teeth on the rim that can continuously mesh to transmit motion and power. When manufacturing gears, it is necessary to remove the burrs on their surfaces, that is, to remove the thorns or flash formed at the intersection of the parts' surfaces. At present, when deburring the oil pump gear, a disc brush is usually used to rub the end face and the tooth groove of the gear manually. In particular, the grinding of several tooth grooves on the gear needs to be done one by one, which is inconvenient to operate and leads to low work efficiency, so it needs to be improved. Summary of the invention

[0003] In order to improve the problem of low work efficiency due to the need to manually grind several tooth grooves of a gear one by one, the present application provides a gear deburring grinding device.

[0004] The present application provides a gear deburring and grinding device that adopts the following technical solution: A gear deburring and grinding device comprises a working cylinder, an internal gear, a rotating motor and a mounting frame, wherein the internal gear is horizontally arranged on the working cylinder, and a moving component is provided on the working cylinder, and the moving component is used to drive the internal gear to move up and down, and the rotating motor is arranged on the working cylinder, and the output shaft of the rotating motor is coaxial with the internal gear, and the rotating motor is connected to the mounting frame and is used to drive the mounting frame to rotate with the rotating motor as the axis, and the mounting frame is used to install the gear, and the internal gear can mesh with the gear.

[0005] By adopting the above technical solution, when working, the gear to be processed is installed on the mounting frame so that the gear is meshed with the internal gear, and then the rotating motor is started to drive the gear to make a circular motion with the internal gear as the axis. At the same time, the gear is meshed with the internal gear for transmission, so that the gear rotates on its own, and the gear moves along the internal gear, and a number of gear tooth grooves on the gear contact different parts of the internal gear in turn; At this time, the moving component is started to drive the internal gear to move up and down, so that the internal gear slides against the inner wall of the gear tooth groove, thereby grinding the inner wall of the gear tooth groove and removing the burrs on the inner wall of the gear tooth groove. After the gear moves one circle, the grinding of all the gear tooth grooves on the entire gear can be completed. The operation is convenient and the work efficiency is high.

[0006] Optionally, the moving component includes a moving cylinder and a moving rod, the moving cylinder is arranged on the working cylinder, the output end of the moving cylinder can abut against the top wall of the internal gear and drive the internal gear to move downward, the moving rod is fixed to the output shaft of the moving cylinder, and the moving rod is inserted into the working cylinder and abuts against the bottom wall of the internal gear.

[0007] By adopting the above technical solution, the moving cylinder is started, and when the output shaft of the moving cylinder moves downward, the moving rod moves downward synchronously. When the output end of the moving cylinder abuts against the top wall of the internal gear, the internal gear is driven to move downward. Then the moving cylinder is reset, driving the moving rod to move upward synchronously, so that the moving rod abuts against the bottom wall of the internal gear and supports the internal gear to move upward, thereby realizing reciprocating movement of the internal gear in the vertical direction, so as to realize back and forth grinding of the inner wall of the gear tooth groove.

[0008] Optionally, a guide block is fixed on the outer wall of the internal gear, and a guide groove is opened on the inner wall of the working cylinder in the vertical direction. The guide block is inserted in the guide groove and can move in the guide groove. The guide block is connected to the inner wall of the guide groove through a support spring, and the support spring is used to drive the guide block to move upward.

[0009] By adopting the above technical solution, when the moving cylinder drives the internal gear to move, the guide block moves in the guide groove, and the inner wall of the guide groove abuts against the guide block, which plays a role of limiting the guide, so that the internal gear is not easy to deflect during the movement, and the stability of the internal gear moving up and down to grind the gear is increased. When the internal gear moves, the support spring is deformed. During the resetting process of the moving cylinder, that is, when the moving cylinder and the moving rod have not yet contacted the internal gear, the support spring loses the external force at this time, thereby recovering the deformation and driving the internal gear to reset. Due to the elastic force and inertia of the support spring itself, the support spring constantly vibrates up and down, thereby driving the high-frequency up and down movement of the internal gear to achieve multiple grinding of the gear tooth groove, thereby improving the grinding accuracy and the grinding efficiency. The moving distance of the internal gear is only the telescopic distance of the support spring, that is, the moving distance is small, which will not affect the meshing of the gear and the internal gear.

[0010] Optionally, the working cylinder is connected to a connecting plate via a lifting cylinder, the connecting plate is connected to a grinding disc via a rotating motor, the grinding disc is located above the mounting frame, and the grinding disc can contact the top wall of the gear.

[0011] By adopting the above technical solution, while the gear is moving, the lifting cylinder is started to drive the connecting plate with the grinding disc to move downward until the grinding disc contacts the top wall of the gear, and the gear rotates while revolving around the rotating motor, so that the top wall of the gear rotates relatively on the grinding disc. These two motion modes act simultaneously, increasing the contact frequency between the gear and the grinding disc. At the same time, the rotating motor is started to drive the grinding disc to rotate, further improving the grinding efficiency, and then improving the grinding accuracy of the grinding disc on the top wall of the gear. The grinding disc can move up and down, so that it can contact with gears of different thicknesses, which is suitable for grinding the end faces of gears of different thicknesses, and has better applicability.

[0012] Optionally, a mounting plate is connected to the mounting frame via a conversion motor, the mounting plate is horizontally arranged, and both ends of the mounting plate are provided with positioning components, and the positioning components are used to fix the gears.

[0013] By adopting the above technical solution, the two gears are respectively installed on the two positioning components, and only one gear is meshed with the internal gear at a time. When the grinding of the tooth groove of one of the gears is completed, the moving cylinder is first started to drive the internal gear down until the internal gear is separated from the gear. Then, the conversion motor is started to drive the mounting plate to rotate so that the positions of the two gears are changed. At this time, the moving cylinder drives the internal gear to reset so that the other gear is meshed with the internal gear, thereby realizing the grinding of the other gear. When both gears are polished, the entire grinding device is stopped, the polished gears are removed, and new gears to be processed are placed. That is, the grinding device can grind two gears each time it operates, and there is no need to stop working after grinding one gear, and the gears can be disassembled and assembled, thereby improving the overall work efficiency.

[0014] Optionally, the positioning assembly includes a support rod and a bidirectional cylinder, the support rod is arranged at the end of the mounting plate, the bidirectional cylinder is arranged on the support rod, the gear can be sleeved on the support rod, and the two output ends of the bidirectional cylinder are both in contact with the inner wall of the gear.

[0015] By adopting the above technical solution, after the gear is sleeved on the support rod, the two-way cylinder is located inside the gear. At this time, the two-way cylinder is started so that the two output ends of the two-way cylinder are in contact with the inner wall of the gear, so that the gear and the support rod are coaxial, and the positioning of the gear on the support rod is realized. When the gear is meshed and transmitted on the internal gear, the gear rotates on the support rod with the support rod as the axis. The two axes of the two-way cylinder can be extended or shortened at the same time, so that gears with different apertures can be limited, and the adaptability is better. The gear is only sleeved on the support rod. When the internal gear moves up and down, the oblique thrust will drive the gear to vibrate slightly along the axial direction to ensure the meshing of the gear and the internal gear.

[0016] Optionally, a flip assembly is provided at the end of the mounting plate, and the flip assembly is connected to a support rod, and the support rod is driven to drive the gear to flip up and down.

[0017] By adopting the above technical solution, when the top wall of the gear is polished by the polishing disc, the flipping assembly is started to drive the gear to flip so that the bottom wall of the gear faces upward, thereby achieving double-sided polishing of the gear by the polishing disc and improving the polishing accuracy.

[0018] Optionally, the flipping assembly includes a flipping motor, a flipping block, a flipping cylinder and a connecting block, the flipping motor is arranged at the end of the mounting plate, the output shaft of the flipping motor is horizontal and fixedly connected to the flipping block, the flipping cylinder is arranged on the flip block, a socket is provided at the end of the flipping block, the output shaft of the flipping cylinder passes through the socket and is connected to the connecting block, the connecting block can rotate on the output shaft of the flipping cylinder, the flipping cylinder can drive the connecting block to fit into the socket, and the connecting block is fixed to the end of the support rod.

[0019] By adopting the above technical solution, in the initial state, the connecting block is inserted into the socket, the support rod is in a vertical upward state, and the connecting block is fixedly connected to the flip block. When the gear needs to be flipped, the flip cylinder is started to drive the connecting block to be pulled out of the flip block. At this time, the connecting block loses the restriction of flipping. Due to the heavy weight of the support rod and the gear, it will flip downward under the action of gravity, that is, the connecting rod rotates with the flip cylinder as the axis until the support rod turns to a vertical downward state, so that the gear falls off the support rod, realizing automatic unloading of the gear, and the operation is convenient.

[0020] Optionally, an air blowing pipe is provided on the inner wall of the working cylinder, and the air blowing pipe is located below the mounting frame.

[0021] By adopting the above technical solution, a lot of debris will be generated during the process of grinding the gear burrs. At this time, the air blow pipe is started to blow air in the direction of the gear to blow away the debris, so as to prevent the debris from covering the gear and increasing friction, thereby affecting the grinding accuracy. At the same time, when the grinding device is working, the grinding disc is moved down to contact the top wall of the gear, thereby blocking the top opening of the working cylinder, making the entire working cylinder a relatively closed space, preventing debris from floating in the surrounding environment, reducing the impact on air quality, reducing resource waste, and protecting the health of workers.

[0022] Optionally, a discharge port is provided on the side wall of the working cylinder, a bottom plate is provided at the bottom of the working cylinder, a sealing plate is fixed on the bottom plate, and the sealing plate can seal the discharge port.

[0023] By adopting the above technical solution, the debris generated by grinding the gears will eventually fall onto the bottom plate, directly pulling the sealing plate to move the sealing plate away from the working cylinder, thereby pulling the bottom plate out of the working cylinder and cleaning the debris in the working cylinder.

[0024] In summary, the present application includes at least one of the following beneficial effects: 1. Start the rotating motor to drive the gear to do circular motion with the internal gear as the axis. At the same time, the gear meshes with the internal gear to make the gear rotate, so that the gear moves along the internal gear, and several gear grooves on the gear contact different parts of the internal gear in turn. At this time, start the moving component to drive the internal gear to move up and down, so that the internal gear slides against the inner wall of the gear groove, so as to grind the inner wall of the gear groove and remove the burrs on the inner wall of the gear groove. After the gear moves one circle, the grinding of all the gear grooves on the entire gear can be completed. The operation is convenient and the work efficiency is high. 2. When the internal gear moves, the support spring is deformed. During the resetting process of the moving cylinder, that is, before the moving cylinder and the moving rod come into contact with the internal gear, the support spring loses the external force and recovers its deformation, driving the internal gear to reset. Due to the elastic force and inertia of the support spring itself, the support spring vibrates up and down continuously, thereby driving the internal gear to move up and down at a high frequency, so as to realize multiple grinding of the gear tooth groove, improve the grinding accuracy and improve the grinding efficiency.

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-4 This application is described in further detail.

[0028] The present application embodiment discloses a gear deburring grinding device. Figure 1 and Figure 2 The gear deburring grinding device comprises a working cylinder 10, an internal gear 20, a rotating motor 30 and a mounting frame 31, wherein the internal gear 20 is horizontally arranged on the working cylinder 10, and a gear brush is arranged on the side wall of each tooth on the internal gear 20, which can grind the gear tooth groove of the gear. A moving assembly 40 is arranged on the working cylinder 10, and the moving assembly 40 is used to drive the internal gear 20 to move up and down. The rotating motor 30 is arranged on the working cylinder 10, and the output shaft of the rotating motor 30 and the internal gear 20 are both coaxial with the working cylinder 10, and the rotating motor 30 is connected to the mounting frame 31, which is used to drive the mounting frame 31 to rotate with the rotating motor 30 as the axis, and the mounting frame 31 is used to install the gear, and the internal gear 20 can mesh with the gear.

[0029] Reference Figure 1 and Figure 2 The top of the working cylinder 10 is open, and a lifting cylinder 50 is installed on the top of the working cylinder 10 by bolts. The output end of the lifting cylinder 50 is vertically upward and fixed with a connecting plate 51. The connecting plate 51 is horizontally arranged, and a rotating motor 60 is installed on the connecting plate 51. A grinding disc 61 is coaxially fixed to the output end of the rotating motor 60, which is used to drive the grinding disc 61 to rotate, wherein the grinding disc 61 is coaxial with the working cylinder 10, and the grinding disc 61 can be lowered to block the top opening of the working cylinder 10 under the drive of the lifting cylinder 50.

[0030] During operation, the gear to be processed is mounted on the mounting frame 31 so that the gear is meshed with the internal gear 20. Then the rotating motor 30 is started to drive the gear to perform circular motion with the internal gear 20 as the axis. At the same time, the gear is meshed with the internal gear 20 for transmission, so that the gear rotates on its own, and the gear moves along the internal gear 20, and several tooth grooves on the gear contact different parts of the internal gear 20 in turn.

[0031] Reference Figure 1 and Figure 2 At this time, the moving assembly 40 is started to drive the internal gear 20 to move up and down, so that the internal gear 20 slides against the inner wall of the gear tooth groove, thereby grinding the inner wall of the gear tooth groove and removing the burrs on the inner wall of the gear tooth groove.

[0032] Reference Figure 1 and Figure 2When the gear moves, the lifting cylinder 50 is started to drive the connecting plate 51 to move downward with the grinding disc 61 until the grinding disc 61 contacts the top wall of the gear. The gear rotates while revolving around the rotating motor 30, so that the top wall of the gear rotates relatively on the grinding disc 61. These two motion modes act at the same time, increasing the contact frequency between the gear and the grinding disc 61. At the same time, the rotating motor 60 is started to drive the grinding disc 61 to rotate, further improving the grinding efficiency, and then improving the grinding accuracy of the grinding disc 61 on the top wall of the gear. The grinding disc 61 can move up and down, so that it can contact with gears of different thicknesses, which is suitable for grinding the end faces of gears of different thicknesses, and has better applicability.

[0033] At the same time, when the grinding device is working, the grinding disc 61 moves down to contact the top wall of the gear, thereby blocking the top opening of the working cylinder 10, making the entire working cylinder 10 a relatively closed space, preventing debris from floating in the surrounding environment, reducing the impact on air quality, reducing resource waste, and ensuring the health of staff.

[0034] Reference Figure 1 and Figure 2 Specifically, the moving assembly 40 includes a moving cylinder 41 and a moving rod 42. The moving cylinder 41 is installed on the top of the working cylinder 10, and the output end of the moving cylinder 41 can abut against the top wall of the internal gear 20 and drive the internal gear 20 to move downward. The moving rod 42 is fixed to the output shaft of the moving cylinder 41, and the moving rod 42 is inserted into the working cylinder 10 and abuts against the bottom wall of the internal gear 20.

[0035] Start the moving cylinder 41. When the output shaft of the moving cylinder 41 moves downward, the moving rod 42 moves downward synchronously. When the output end of the moving cylinder 41 abuts against the top wall of the internal gear 20, the internal gear 20 is driven to move downward. Then the moving cylinder 41 is reset, driving the moving rod 42 to move upward synchronously, so that the moving rod 42 abuts against the bottom wall of the internal gear 20 and supports the internal gear 20 to move upward, thereby realizing the reciprocating movement of the internal gear 20 in the vertical direction, so as to realize the back and forth grinding of the inner wall of the gear tooth groove.

[0036] Reference Figure 1 and Figure 2 A guide block 21 is fixed on the outer wall of the internal gear 20. The guide block 21 is a rectangular block. A guide groove 12 is opened on the inner wall of the working cylinder 10 in the vertical direction. The guide groove 12 is linear. The guide block 21 is inserted in the guide groove 12 and can move in the guide groove 12. The guide block 21 is connected to the inner wall of the guide groove 12 through a support spring 22. The support spring 22 is used to drive the guide block 21 to move upward.

[0037] When the moving cylinder 41 drives the internal gear 20 to move, the guide block 21 moves in the guide groove 12, and the inner wall of the guide groove 12 abuts against the guide block 21, which plays a role in limiting the guide, so that the internal gear 20 is not easy to deflect during the movement, and the stability of the internal gear 20 moving up and down to grind the gear is increased. When the internal gear 20 moves, the support spring 22 is deformed. During the reset process of the moving cylinder 41, that is, when the moving cylinder 41 and the moving rod 42 have not yet contacted the internal gear 20, the support spring 22 loses the external force at this time, thereby recovering the deformation and driving the internal gear 20 to reset. Due to the elastic force and inertia of the support spring 22 itself, the support spring 22 constantly vibrates up and down, thereby driving the internal gear 20 to move up and down at a high frequency, so as to realize multiple grinding of the gear tooth groove, improve the grinding accuracy, and improve the grinding efficiency. Among them, the moving distance of the internal gear 20 is only the telescopic distance of the support spring 22, that is, the moving distance is small, which will not affect the meshing of the gear and the internal gear 20.

[0038] Reference Figure 2 and Figure 3 In order to improve work efficiency, there is no need to stop working after grinding a gear. The gear to be processed can be disassembled and assembled. A mounting plate 71 is connected to the mounting frame 31 through a conversion motor 70. The mounting plate 71 is arranged horizontally. Both ends of the mounting plate 71 are provided with positioning components 80, which are used to fix the gear.

[0039] Reference Figure 2 and Figure 3 Specifically, the positioning assembly 80 includes a support rod and a two-way cylinder 82. The support rod 81 is arranged at the end of the mounting plate 71, and the two-way cylinder 82 is arranged on the support rod 81. The gear can be sleeved on the support rod 81, and the two output ends of the two-way cylinder 82 are both in contact with the inner wall of the gear.

[0040] When the gear is sleeved on the support rod 81, the two-way cylinder 82 is located inside the gear. At this time, the two-way cylinder 82 is started, so that the two output ends of the two-way cylinder 82 are in contact with the inner wall of the gear, so that the gear and the support rod 81 are coaxial, and the positioning of the gear on the support rod 81 is realized. When the gear is meshed and transmitted on the internal gear 20, the gear rotates on the support rod 81 with the support rod 81 as the axis. The two axes of the two-way cylinder 82 can be extended or shortened at the same time, so that gears with different apertures can be limited, and the adaptability is better. The gear is only sleeved on the support rod 81. When the internal gear 20 moves up and down, the oblique thrust will drive the gear to vibrate slightly along the axial direction to ensure the meshing of the gear with the internal gear 20.

[0041] Reference Figure 2 and Figure 3, and after the gears are mounted on the two support rods 81, only one gear is meshed with the internal gear 20 at a time. When the grinding of the tooth groove of one of the gears is completed, the moving cylinder 41 is first started to drive the internal gear 20 down until the internal gear 20 is separated from the gear. Then, the conversion motor 70 is started to drive the mounting plate 71 to rotate so that the positions of the two gears are changed. At this time, the moving cylinder 41 drives the internal gear 20 to reset so that the other gear is meshed with the internal gear 20, thereby achieving the grinding of the other gear. When both gears are polished, the entire grinding device is stopped, the polished gear is removed, and a new gear to be processed is placed. That is, the grinding device can grind two gears each time it is operated, thereby improving the overall work efficiency.

[0042] Reference Figure 3 and Figure 4 In order to facilitate material cutting, a flip assembly 90 is provided at the end of the mounting plate 71. The flip assembly 90 includes a flip motor 91, a flip block 92, a flip cylinder 93 and a connecting block 94. The flip motor is provided at the end of the mounting plate 71. The output shaft of the flip motor 91 is horizontal and fixedly connected to the flip block 92. The flip cylinder 93 is provided on the flip block. A socket 921 is provided at the end of the flip block 92. The socket 921 is a square hole.

[0043] Reference Figure 3 and Figure 4 The output shaft of the flip cylinder 93 passes through the socket 921 and is connected to the connecting block 94. The connecting block 94 can rotate on the output shaft of the flip cylinder 93. The connecting block 94 is a square block. The flip cylinder 93 can drive the connecting block 94 to fit into the socket 921, that is, the square block is inserted into the square hole, so that the connecting block 94 is fixed to the flip block and will not flip. The connecting block 94 and the end of the support rod 81 are integrally formed to form an L-shaped rod. When the connecting block 94 is in the socket 921, the state of the support rod 81 is fixed.

[0044] In the initial state, the connecting block 94 is inserted into the insertion hole 921, and the support rod 81 is in a vertically upward state. At this time, the connecting block 94 is fixedly connected to the flip block 92. When the gear needs to be flipped, the flip cylinder 93 is started to drive the connecting block 94 to be pulled out of the flip block 92. At this time, the connecting block 94 loses the restriction of flipping. Due to the heavy weight of the support rod 81 and the gear, it will flip downward under the action of gravity, that is, the connecting rod rotates with the flip cylinder 93 as the axis until the support rod 81 rotates to a vertically downward state, so that the gear falls off the support rod 81, and the gear is automatically unloaded.

[0045] Then, the flip cylinder 93 is used to drive the connecting block 94 to be reinserted into the socket 921, so that the support rod 81 remains in a vertical downward position, and then the flip motor 91 is started to drive the entire flip block 92 to rotate until the support rod 81 is driven vertically upward and then stops, so as to load the gear to be processed.

[0046] Reference Figure 1 and Figure 2 In order to reduce the impact of debris generated during the grinding process on the grinding work, an air blowing pipe 13 is provided on the inner wall of the working cylinder 10, and the air blowing pipe 13 is located below the mounting frame 31. In the process of grinding the gear burrs, a lot of debris will be generated. At this time, the air blowing pipe 13 is started to blow air toward the gear to blow away the debris, so as to prevent the debris from covering the gear and increasing friction, thereby affecting the grinding accuracy.

[0047] Reference Figure 1 and Figure 2 In order to facilitate the cleaning of debris in the working cylinder 10 and the discharge of gears, a discharge port 11 is opened on the side wall of the working cylinder 10, and a bottom plate 110 is provided at the bottom of the working cylinder 10. A sealing plate 120 is fixed on the bottom plate 110, and the sealing plate 120 can block the discharge port 11.

[0048] The debris generated by grinding the gear will eventually fall onto the bottom plate 110, directly pulling the closing plate 120, so that the closing plate 120 moves away from the working cylinder 10, thereby pulling the bottom plate 110 out of the working cylinder 10, and cleaning the debris in the working cylinder 10. At the same time, the gear that slides off the support rod 81 will fall onto the bottom plate 110, and move out of the working cylinder 10 with the bottom plate 110, so that the gear can be discharged.

[0049] The implementation principle of the gear deburring grinding device of the embodiment of the present application is as follows: when working, the gear to be processed is mounted on the mounting frame 31, so that the gear is meshed with the internal gear 20, and then the rotating motor 30 is started to drive the gear to make a circular motion with the internal gear 20 as the axis. At the same time, the gear is meshed with the internal gear 20 for transmission, so that the gear rotates, and the gear moves along the internal gear 20, and a plurality of gear tooth grooves on the gear sequentially contact different parts of the internal gear 20; At this time, the moving component 40 is started to drive the internal gear 20 to move up and down, so that the internal gear 20 slides against the inner wall of the gear tooth groove, thereby grinding the inner wall of the gear tooth groove and removing the burrs on the inner wall of the gear tooth groove. After the gear moves one circle, the grinding of all the gear tooth grooves on the entire gear can be completed, the operation is convenient, and the work efficiency is high.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
