Description

Technical Field

[0001] This invention relates to the field of deburring technology for arc-shaped teeth, specifically to a deburring platform for arc-shaped teeth. Background Technology

[0002] Arc-shaped end teeth are common mechanical parts, typically used to transmit torque and motion. However, during machining, burrs may form on the surface of these teeth. These burrs not only affect the appearance quality of the parts but may also impact their assembly and performance. Therefore, an effective burr removal device is needed to remove burrs from the surface of arc-shaped end teeth.

[0003] In the patent application with publication number CN217913232U, publication date 2022-11-29, entitled "A Burr Removal Device for Arc-shaped End Teeth of Metal Parts", four sets of scrapers are set up, and each set of scrapers is driven by a connecting component and a first telescopic cylinder, so that each scraper is relatively independent. On the one hand, this can improve the efficiency of burr removal. On the other hand, the scrapers are attached to the end teeth. When the end teeth rotate, the four scrapers may be located at the root, tip, or surface of the end teeth respectively. This does not affect the overall burr removal of the end teeth. That is to say, there is no need to consider the synchronization of the four scrapers. However, if the movement of the scrapers is not synchronized, burrs may remain in some areas. Furthermore, for some special shapes or positions of the outer circular surface, burrs may not be completely removed, requiring additional processing steps. At the same time, there may be certain limitations on the shape and size of the parts. It may not be fully adaptable to parts with complex shapes or special requirements.

[0004] Therefore, we propose a burr removal platform for arc-shaped teeth to solve the problems mentioned above. Summary of the Invention

[0005] 1. The technical problem that the invention aims to solve: The purpose of this invention is to provide a burr removal platform for arc-shaped end teeth to solve the problems currently found in the market as described in the background art.

[0006] 2. Technical Solution: To achieve the above objectives, the present invention provides the following technical solution: a burr removal platform for arc-shaped end teeth, comprising a base plate and an arc-shaped end tooth body, wherein a magnetic grinding barrel is fixedly fixed at the upper middle part of the base plate, and an electric push rod is installed on the upper side of the base plate, and a top plate is fixedly connected to the output end of the electric push rod, and a rotating connector is installed at the lower end of the top plate, the rotating connector comprising a rotating plate mounted on the lower end of the top plate by bearings, and rotating rods are fixed at the lower ends of the left and right sides of the rotating plate, and a bearing plate is rotatably installed between the two rotating rods, wherein a plurality of limiting mechanisms are installed inside the bearing plate, the limiting mechanisms being used to fix the arc-shaped end tooth body; A rotating drum is mounted on the inner side of the magnetic grinding barrel via a bearing, and an auxiliary mechanism is mounted on the rotating drum. The auxiliary mechanism is used to drive the rotating plate to rotate. A driving component is mounted on the side of the magnetic grinding barrel, and the driving component is used to drive the rotating drum to rotate.

[0007] Furthermore, the limiting mechanism includes a movable rod that is flat and slidably installed inside the support plate. A clamping plate is fixed to the lower side of the movable rod, and a roller is rotatably installed at the upper end of the movable rod. The roller is located inside the slide groove, which is arc-shaped and opened inside the driven gear. The driven gear is mounted above the support plate via a bearing.

[0008] The above technical solution enables the driven gear to rotate and drive the clamping plate to move.

[0009] Furthermore, the movable rod has a cross-shaped structure design, and the clamping plates are distributed at equal angles with respect to the center of the driven gear.

[0010] The above technical solution enables the clamping plate to hold and fix the arc-shaped end tooth body.

[0011] Furthermore, a control mechanism is installed in the middle of the support plate. The control mechanism includes a frame fixedly installed in the middle of the support plate, and a set of meshing worm gears and worms are installed inside the frame through bearings. A drive gear is fixed to the end of the worm gear, and the drive gear and the driven gear are meshed together.

[0012] The above technical solution enables the drive gear at the end of the worm wheel to rotate by rotating the worm, which in turn drives the driven gear to rotate.

[0013] Furthermore, guide gears are fixedly connected to both ends of the bearing plate shaft, and force-bearing rods are fixed to both the left and right sides of the lower end of the bearing plate.

[0014] The above technical solution enables the guide gear to drive the bearing plate to rotate.

[0015] Furthermore, the auxiliary mechanism consists of a gear ring, a rack, and a drive plate. The gear ring is fixedly sleeved on the outside of the rotating cylinder, and the racks are symmetrically installed in two sets on the inner walls of the left and right sides of the rotating cylinder. The drive plates are symmetrically installed in two sets on the inner walls of the left and right sides of the rotating cylinder.

[0016] The above technical solution enables the guide gear to rotate when the rack is displaced on the side.

[0017] Furthermore, the gear ring is rotated by a driving component, which includes a motor mounted on the outside of the magnetic grinding barrel, and a drive gear is fixed at the output end of the motor, and the drive gear meshes with the gear ring.

[0018] The above technical solution enables the motor to drive the gear ring to rotate via the drive gear after it starts.

[0019] Furthermore, the left and right racks are respectively meshed with the left and right guide gears.

[0020] The above technical solution enables the guide gear to rotate, thereby driving the bearing plate to rotate.

[0021] Furthermore, the minimum distance between the two drive plates is less than the maximum distance between the two force rods, and the lowest position of the force rod is lower than the lowest position of the drive plate.

[0022] The above technical solution enables the bearing plate to rotate by the contacting action of the drive plate and the force rod after the drum rotates.

[0023] 3. Beneficial effects: Compared with the prior art, the burr removal platform for arc-shaped end teeth of this invention, after fixing the arc-shaped end tooth body through a limiting mechanism, performs magnetic grinding on the arc-shaped end tooth through a magnetic grinding barrel. Then, the auxiliary mechanism on the rotating drum drives the arc-shaped end tooth body to perform efficient cleaning and spin drying. The specific details are as follows: After fixing the arc-shaped end tooth body to the support plate through the limiting mechanism, add clean water, grinding magnetic needles and an appropriate amount of polishing liquid to the magnetic grinding barrel, start the electric push rod, the electric push rod drives the top plate to move downward. During the downward movement, it drives the guide gear to mesh with the rack. During the meshing process, it drives the guide gear to rotate. During the rotation of the guide gear, it drives the support plate to rotate synchronously, flipping the arc-shaped end tooth body fixed on the support plate to the bottom of the support plate. Adjust the speed, time and other parameters of the magnetic grinding through the existing controller to perform multi-directional grinding on the arc-shaped end tooth body and improve the deburring effect. After the deburring operation is completed, the wastewater in the magnetic grinding tank is drained through the drain pipe, while cleaning solution is added to the magnetic grinding tank through the water injection pipe. Then, the motor is started, and the motor drives the drive gear to rotate. The drive gear, through meshing with the gear ring, drives the rotating drum to rotate. During the rotation of the drum, the contact between the drive plate and the force rod drives the support plate and rotating connecting parts to rotate below the top plate. At the same time, the motor can be started in reverse, and through the contact between the drive plate on the other side and the corresponding force rod, the support plate and rotating connecting parts are driven to rotate in the opposite direction below the top plate. This achieves efficient cleaning of the arc-shaped end teeth fixed on the support plate, improving the cleaning effect. Afterward, the water is drained, and the rotation of the support plate is maintained. The water droplets adhering to the arc-shaped end teeth are thrown off under centrifugal force.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0027] Please see Figure 1-7 This invention provides a technical solution: a burr removal platform for arc-shaped end teeth, comprising a base plate 1 and an arc-shaped end tooth body 9. A magnetic grinding barrel 2 is fixed to the upper middle part of the base plate 1, and an electric push rod 3 is installed on the upper side of the base plate 1. The output end of the electric push rod 3 is fixedly connected to a top plate 4, and a rotating connector 5 is installed at the lower end of the top plate 4. The rotating connector 5 includes a rotating plate 51 mounted to the lower end of the top plate 4 via bearings, and rotating rods 52 are fixed to the lower ends of the left and right sides of the rotating plate 51. A bearing plate 6 is rotatably mounted between the two rotating rods 52. Several sets of limiting mechanisms 8 are installed inside the bearing plate 6. The limiting mechanisms 8 are used to fix the arc-shaped end tooth body 9. The limiting mechanisms 8 include movable rods 81 that are flat and slidably mounted inside the bearing plate 6. A clamping plate 82 is fixed to the lower side, and a roller 83 is rotatably mounted on the upper end of the movable rod 81. The roller 83 is located inside the slide groove 85, which is arc-shaped and located inside the driven gear 84. The driven gear 84 is mounted on the upper part of the support plate 6 via a bearing. The movable rod 81 has a cross-shaped structure design, and the clamping plate 82 is distributed at equal angles with respect to the center of the driven gear 84. A control mechanism 10 is installed in the middle of the support plate 6. The control mechanism 10 includes a frame 101 fixedly installed in the middle of the support plate 6. A set of meshing worm gears 102 and worms 103 are installed inside the frame 101 via bearings. A drive gear 104 is fixed to the end of the worm gear 102, and the drive gear 104 and the driven gear 84 form a meshing connection. Before deburring the arc-shaped end tooth body 9, the clamping plate 82 is positioned above the support plate 6, making it easy for the operator to place the arc-shaped end tooth body 9 on the support plate 6. Then, the worm 103 is rotated. The worm 103 drives the worm wheel 102 and the drive gear 104 fixed at the end of the worm wheel 102 to rotate through the meshing action between the worm wheel 103 and the worm wheel 102. During the rotation, the drive gear 104 drives the driven gear 84 to rotate through the meshing action between the drive gear 104 and the driven gear 84. During the rotation of the driven gear 84, pressure is applied to the roller 83 through the sliding groove 85. Since the movable rod 81 slides vertically inside the support plate 6, the clamping plate 82 can be moved towards the side of the arc-shaped end tooth body 9 until it fits against the side of the arc-shaped end tooth body 9, thus achieving the fixing operation of the arc-shaped end tooth body 9. A rotating drum 12 is mounted on the inner side of the magnetic grinding barrel 2 via bearings, and an auxiliary mechanism is mounted on the rotating drum 12. The auxiliary mechanism is used to drive the rotating plate 51 to rotate. A driving component 11 is mounted on the side of the magnetic grinding barrel 2, and the driving component 11 is used to drive the rotating drum 12 to rotate. Guide gears 7 are fixedly connected to both ends of the bearing plate shaft, and force-bearing rods 61 are fixed on both sides of the lower end of the bearing plate 6. The auxiliary mechanism consists of a gear ring 121, a rack 122, and a driving plate 123. The gear ring 121 is fixedly sleeved on the rotating drum 12. The outer side of the cylinder 12, and the racks 122 are symmetrically installed in two sets on the inner walls of the left and right sides of the rotating cylinder 12, and the drive plates 123 are symmetrically installed in two sets on the inner walls of the left and right sides of the rotating cylinder 12; the gear ring 121 is rotated by the drive member 11, which includes a motor 111 installed on the outer side of the magnetic grinding barrel 2, and the output end of the motor 111 is fixed with a drive gear 112, and the drive gear 112 meshes with the gear ring 121; the left and right racks 122 are respectively meshed with the left and right guide gears 7; After the arc-shaped end tooth body 9 is fixed to the bearing plate 6 by the limiting mechanism 8, clean water, grinding magnetic needle and appropriate amount of polishing liquid are added to the magnetic grinding barrel 2. The electric push rod 3 is started. The electric push rod 3 drives the top plate 4 to move downward. During the downward movement, the guide gear 7 is driven to mesh with the rack 122. During the meshing process, the guide gear 7 is driven to rotate. During the rotation of the guide gear 7, the bearing plate 6 is driven to rotate synchronously. The arc-shaped end tooth body 9 fixed on the bearing plate 6 is flipped to the bottom of the bearing plate 6. The speed, time and other parameters of magnetic grinding are adjusted by the existing controller to perform multi-directional grinding on the arc-shaped end tooth body 9 to improve the deburring effect. The minimum distance between the two drive plates 123 is less than the maximum distance between the two force rods 61, and the lowest position of the force rod 61 is lower than the lowest position of the drive plate 123. After the deburring operation is completed, the wastewater in the magnetic grinding tank 2 is discharged through the drain pipe, and cleaning water is added to the magnetic grinding tank 2 through the water injection pipe. Then, the motor 111 is started, and the motor 111 drives the drive gear 112 to rotate. The drive gear 112 drives the rotating drum 12 to rotate by meshing with the gear ring 121. During the rotation of the rotating drum 12, the drive plate 123 and the force rod 61 are in contact to drive the bearing plate 6 and the rotating connecting piece 5 to rotate below the top plate 4. At the same time, the motor 111 can be started in reverse, and the drive plate 123 on the other side and the corresponding force rod 61 are in contact to drive the bearing plate 6 and the rotating connecting piece 5 to rotate in the opposite direction below the top plate 4. This achieves efficient cleaning of the arc-shaped end tooth body 9 fixed on the bearing plate 6, improving the cleaning effect. Then, the water is discharged, and the bearing plate 6 is kept rotating. The water droplets adhering to the arc-shaped end tooth body 9 can be thrown out under centrifugal force.

[0028] Working principle: When using this arc-shaped end toothed deburring platform, such as Figure 1-7 As shown, firstly, the arc-shaped end tooth body 9 is fixed to the support plate 6 by the limiting mechanism 8. Then, clean water, grinding magnetic needle and appropriate amount of polishing liquid are added to the magnetic grinding barrel 2. Then, the electric push rod 3 is started, which drives the guide gear 7 to mesh with the rack 122, flipping the arc-shaped end tooth body 9 fixed on the support plate 6 to the bottom of the support plate 6. The rotation speed, time and other parameters of the magnetic grinding are adjusted by the existing controller to perform multi-directional grinding on the arc-shaped end tooth body 9 to improve the deburring effect. After the deburring operation is completed, the wastewater in the magnetic grinding tank 2 is discharged through the drain pipe, and at the same time, the cleaning solution is added to the magnetic grinding tank 2 through the water injection pipe. Then, the motor 111 is started in both directions to drive the rotating drum 12 to rotate in both directions, so as to achieve efficient cleaning of the arc-shaped end tooth body 9 fixed on the support plate 6 and improve the cleaning effect. Then, the water is discharged and the support plate 6 is kept rotating. The water droplets adhering to the arc-shaped end tooth body 9 can be thrown off under the centrifugal force.
