Description

Technical Field

[0001] This invention relates to the field of railway locomotive technology, and in particular to a brake disc grinding device. Background Technology

[0002] The brake discs of railway locomotives are located on both sides of the wheel discs and are generally made of air-cooled hardened steel. Brake discs have good wear resistance and are mainly used for braking locomotives.

[0003] Currently, most locomotive brake discs are removed by manual grinding to remove rust. The dust is harmful to the human body and the efficiency is low. In order to grind the brake discs better, the operators often need to manually flip the brake discs and grind them. This process may cause the brake discs to fall, be bumped, or even cause danger. Moreover, manual grinding of brake discs is inefficient and cannot meet the grinding quality requirements. Summary of the Invention

[0004] The purpose of this invention is to provide a brake disc grinding device that can grind brake discs efficiently and conveniently, with high quality, good effect, and safer operation.

The clamping members are slidably connected to the turntable along the radial direction of the turntable. The end of the clamping member away from the turntable is configured to abut against the inner circumferential wall of the brake disc. The multiple clamping members are meshed with multiple transmission gears in a one-to-one correspondence.

[0024] A clamping driver, the output end of which is connected to one of the transmission gears, is capable of driving the transmission gear to rotate.

[0061] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0062] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0065] like Figures 1-9 As shown, this embodiment provides a brake disc grinding device, which includes a support frame 1, a lifting and transporting mechanism 2, a clamping and flipping mechanism 3, a first grinding mechanism 4, a laser rust removal mechanism 5, and a second grinding mechanism 6. The lifting and transporting mechanism 2 is mounted on the support frame 1 and can transport the brake disc 100 to the clamping station. The clamping and flipping mechanism 3 is mounted on the support frame 1 and can clamp and fix the brake disc 100 on the clamping station, drive the brake disc 100 to rotate, and flip the brake disc 100. The first grinding mechanism 4 is mounted on the support frame 1 and can grind the keyway 101 on the brake disc 100. The laser rust removal mechanism 5 is mounted on the support frame 1 and can remove rust from the brake disc 100. The second grinding mechanism 6 is mounted on the support frame 1 and can grind the stepped hole 102 on the brake disc 100.

[0066] In this embodiment, the lifting and transporting mechanism 2 is mounted on the support frame 1, which can transport the brake disc 100 to the clamping station, improving work efficiency and facilitating the clamping and flipping mechanism 3 to clamp and flip the brake disc 100 at the clamping station. The clamping and flipping mechanism 3, mounted on the support frame 1, can clamp and fix the brake disc 100 at the clamping station, preventing it from shaking or falling during grinding and other related operations. The clamping and flipping mechanism 3 drives the brake disc 100 to rotate and flip, allowing it to be ground and rotated simultaneously, improving grinding quality and eliminating the need for manual flipping, thus increasing efficiency. The first grinding mechanism 4 grinds the keyway 101 on the brake disc 100, the laser rust removal mechanism 5 removes rust from the brake disc 100, and the second grinding mechanism 6 grinds the stepped hole 102 on the brake disc 100, thereby improving the grinding quality of the brake disc 100. With the above settings, the brake disc grinding device of this embodiment can grind the brake disc 100 efficiently and conveniently, with high quality, good effect, and safer operation.

[0067] Specifically, such as Figure 1 and Figure 2 As shown, the lifting and transporting mechanism 2 includes a lifting driver 21 and a slide 22. The slide 22 is slidably connected to the support frame 1, and the output end of the lifting driver 21 is connected to the slide 22, enabling the slide 22 to slide vertically. By lifting and lowering the slide 22, the brake disc 100 can be aligned with the height of the clamping station on the clamping and tilting mechanism 3, thus facilitating the transport of the brake disc 100 to the clamping station. Furthermore, this facilitates the transport of the brake disc 100, allowing for a more rational layout of the device to meet the actual grinding requirements of the brake disc 100.

[0068] It is understandable that, such as Figure 1 and Figure 2 As shown, since the clamping and flipping mechanism 3 needs to perform clamping, flipping and rotating operations on the brake disc 100, it needs a certain height to facilitate the operation. The slide table 22 in this embodiment is provided with an opening, and the clamping and flipping mechanism 3 extends upward from the opening to facilitate the related operations on the brake disc 100. The slide table 22 can slide vertically to be flush with the clamping position on the clamping and flipping mechanism 3 to ensure that the brake disc 100 can be smoothly transported to the clamping position.

[0069] More specifically, in this embodiment, the lifting drive 21 includes a motor, a magnetic coupling, a rotating shaft, a sprocket, and a chain. The motor is connected to the rotating shaft via the magnetic coupling, the rotating shaft is connected to the sprocket, the sprocket is engaged with the chain, and the chain is mounted on the slide table 22. The motor drives the rotating shaft to rotate, which in turn drives the sprocket to rotate around its own axis. The rotation of the sprocket then drives the chain to move, thereby realizing the up-and-down movement of the slide table 22. Furthermore, the slide table 22 and the support frame 1 are provided with a slide rail on one side and a slider on the other. The slider is slidably connected to the slide rail, allowing the slide table 22 to slide up and down relative to the support frame 1. At the same time, it also provides a certain guiding effect on the movement of the slide table 22, preventing the slide table 22 from shaking and becoming unstable.

[0070] More specifically, such as Figure 1 and Figure 2 As shown, the support frame 1 includes a column, with a rotating shaft at the top of the column. Both ends of the rotating shaft are equipped with sprockets, which are meshed with two chains. The two chains are connected to both sides of the slide 22, making the slide 22 move more stably and smoothly. Furthermore, to achieve more stable sliding of the slide 22, the specific number of the above-mentioned components is not limited. In other embodiments, the lifting drive 21 includes a motor, a gear, and a rack. The output shaft of the motor is connected to the gear, which meshes with the rack. The rack extends vertically and is connected to the slide 22. The motor drives the gear to rotate, which in turn drives the rack to move, thereby realizing the up-and-down movement of the slide 22. That is, the specific composition of the lifting drive 21 is not limited, as long as it can achieve the above-mentioned functions; further details are omitted here.

[0071] Specifically, such as Figure 1 and Figure 2 As shown, the lifting and transporting mechanism 2 also includes a transport driver and multiple rollers. The multiple rollers are parallel to each other and spaced apart in the horizontal direction on the slide table 22. The output end of the transport driver is connected to the rollers and can drive the rollers to rotate to move the brake disc 100, thereby facilitating the transport operation of the brake disc 100.

[0072] More specifically, in this embodiment, the transport driver includes a motor, a sprocket, and a chain. The output shaft of the motor is connected to the sprocket, the sprocket is engaged with the chain, and the chain is engaged with the sprocket at the end of the roller shaft. The motor drives the sprocket on one side of the motor to rotate, which in turn drives the chain to move. The movement of the chain drives the sprocket at the end of the roller shaft to rotate, which in turn drives multiple roller shafts to rotate around their own axes, thereby achieving stable transport of the brake disc 100. Furthermore, in other embodiments, the transport driver includes a motor, a conveyor roller, and a conveyor belt. The output shaft of the motor is connected to the conveyor roller, which is connected to the conveyor belt. The motor drives the conveyor roller to rotate, which in turn drives the conveyor belt to move, thereby transporting the brake disc 100. That is, the specific structure of the transport driver is not limited, as long as it can achieve the above-mentioned functions.

[0073] Specifically, such as Figure 3 and Figure 4 As shown, the clamping and flipping mechanism 3 includes an adapter frame 31 and a flipping driver 32. The adapter frame 31 is rotatably mounted on the support frame 1, and the flipping driver 32 is mounted on the support frame 1. The output end of the flipping driver 32 is connected to the adapter frame 31, enabling it to drive the adapter frame 31 to rotate and flip the brake disc 100 to a vertical position. Through this arrangement, the brake disc 100 can be flipped under the cooperative action of the aforementioned components, so that one side of the brake disc 100 faces the second grinding mechanism 6, while the side of the brake disc 100 with the keyway 101 and heat dissipation fins faces the first grinding mechanism 4. This facilitates the grinding operations of the first grinding mechanism 4 and the second grinding mechanism 6 on the brake disc 100, and solves the problem of the time-consuming and laborious process of manually flipping the brake disc 100, resulting in higher efficiency.

[0074] More specifically, in this embodiment, the flip drive 32 includes a motor, a first gear, and a second gear. The output shaft of the motor is connected to the first gear, and the first and second gears mesh with each other. The motor drives the first gear to rotate around its own axis, and the rotation of the first gear drives the rotation of the second gear. The second gear is connected to the adapter frame 31 via a rotating shaft, and the rotation of the second gear drives the adapter frame 31 to rotate. This arrangement ensures stable power transmission, and the rotation of the adapter frame 31 is precisely controlled by the motor, thereby driving the brake disc 100 to flip. In other embodiments, the motor can directly drive the adapter frame 31 to rotate, as long as the above-mentioned functions can be achieved. The specific structure of the flip drive 32 is not limited here.

[0075] Specifically, such as Figures 3-7As shown, the clamping and flipping mechanism 3 also includes a turntable 33 and a rotary driver 34. The clamping station is located on the turntable 33, allowing the brake disc 100 to be placed on it. The turntable 33 is rotatably connected to the adapter frame 31, so that when the adapter frame 31 rotates, it drives the turntable 33 to rotate as well, facilitating the flipping of the brake disc 100. The rotation axis of the turntable 33 is perpendicular to the rotation axis of the adapter frame 31, allowing the brake disc 100 to rotate horizontally after flipping to one side of the clamping and flipping mechanism 3 and maintaining a vertical position, facilitating grinding operations. The rotary driver 34 is located on the adapter frame 31, and its output end is connected to the turntable 33, driving the turntable 33 to rotate, thereby rotating the brake disc 100. This makes the rotation of the disc more stable and the operation safer. Furthermore, in this embodiment, the rotary driver 34 includes a rotary drive, which enables the turntable 33 to rotate. Those skilled in the art understand the specific working principle of the rotary drive, which will not be elaborated here. In other embodiments, the rotary driver 34 includes a motor and a coupling. The motor is connected to the turntable 33 via the coupling, thereby driving the turntable to rotate. That is, the specific structure of the rotary driver 34 is not limited, as long as it can achieve the above-mentioned functions.

[0076] Specifically, such as Figures 5-7 As shown, the clamping and flipping mechanism 3 also includes a transmission gear ring 35, transmission gears 36, clamping members 37, and a clamping driver 38. The transmission gear ring 35 is mounted on the turntable 33. Multiple transmission gears 36 are provided, evenly spaced along the circumference of the turntable 33 and rotatably connected to it. The transmission gears 36 mesh with the transmission gear ring 35. Multiple clamping members 37 are provided, spaced along the circumference of the turntable 33 and slidably connected to it radially. One end of each clamping member 37 away from the turntable 33 is configured to abut against the inner circumferential wall of the brake disc 100. Each clamping member 37 meshes with one of the multiple transmission gears 36. The output end of the clamping driver 38 is connected to one of the transmission gears 36. Wheel 36 can drive transmission gear 36 to rotate around its own axis. The rotation of transmission gear 36 can drive clamping member 37 meshing with transmission gear 36 to slide radially along turntable 33, and drive transmission gear ring 35 to rotate around its own axis. The rotation of transmission gear ring 35 can drive other transmission gears 36 to rotate around their own axes, thereby driving other clamping members 37 to slide radially along turntable 33. This allows the end of each clamping member 37 away from turntable 33 to abut against the inner circumferential wall of brake disc 100, thereby clamping and fixing brake disc 100 and preventing brake disc 100 from shaking, falling and bumping during operation.

[0077] More specifically, in this embodiment, the clamping driver 38 includes a swing cylinder. The output end of the swing cylinder is provided with a rotating shaft, which is connected to one of the transmission gears 36. The swing cylinder drives the rotating shaft to rotate, thereby causing the transmission gear 36 to rotate around its own axis, making the power rotation more stable and the structure more compact. In other embodiments, the clamping driver 38 includes a motor and a rotating shaft. The output end of the motor is connected to the rotating shaft, which is connected to one of the transmission gears 36. The motor drives the rotating shaft to rotate, thereby causing the transmission gear 36 to rotate around its own axis. That is, the specific structure of the clamping driver 38 is not limited, as long as it can achieve the above-mentioned functions.

[0078] Specifically, such as Figures 1-4 As shown, the first polishing mechanism 4 includes a sliding plate 41, a polishing disc 42, and a sliding driver 43. The sliding plate 41 is slidably connected to the support frame 1, the polishing disc 42 is connected to the sliding plate 41, and the output end of the sliding driver 43 is connected to the sliding plate 41, which can drive the sliding plate 41 to move towards the second polishing mechanism 6. The sliding of the sliding plate 41 can drive the polishing disc 42 to extend into the keyway 101, thereby polishing the keyway 101.

[0079] More specifically, in this embodiment, the sliding actuator 43 includes a motor, a gear, and a rack. The output shaft of the motor is connected to the gear, and the gear is meshed with the rack. The rack is mounted on the sliding plate 41. The motor drives the gear to rotate around its own axis, and the rotation of the gear causes the rack to move horizontally, thereby causing the sliding plate 41 to slide horizontally and gradually approach the brake disc 100, which is in a vertical position, until the grinding disc 42 extends into the keyway 101 for grinding. Furthermore, the grinding disc 42 is a pneumatic grinding head, which has the advantages of high-speed rotation and flexible operation. In other embodiments, the sliding actuator 43 includes a cylinder, which drives the sliding plate 41 to slide, making it more convenient and stable. That is, the specific structure of the sliding actuator 43 is not limited, as long as it can achieve the above-mentioned functions.

[0080] More specifically, a grinding cylinder is provided on the sliding plate 41, and the output end of the grinding cylinder is connected to the grinding disc 42, which can drive the grinding disc 42 to move up and down, thereby grinding along the extension direction of the keyway 101 and further improving the grinding quality. Furthermore, a wire brush is provided on the grinding disc 42 to improve the grinding effect.

[0081] Specifically, such as Figure 1 and Figure 8As shown, the laser rust removal mechanism 5 includes a connecting frame 51, a laser 52, and a rust removal driver 53. The connecting frame 51 is rotatably connected to the support frame 1, and the rotation axis of the connecting frame 51 is parallel to the rotation axis of the brake disc 100 when it is flipped. The laser 52 is mounted on the connecting frame 51, and through the rotation of the connecting frame 51, the laser 52 can perform rust removal on the sides of the brake disc 100. The output end of the rust removal driver 53 is connected to the connecting frame 51, and can drive the connecting frame 51 to rotate. The rotation of the connecting frame 51 can drive the laser 52 to perform laser rust removal on both sides of the brake disc 100, thereby ensuring the quality of the rust removal operation of the brake disc 100.

[0082] More specifically, in this embodiment, the rust removal actuator 53 includes a motor, the output end of which is connected to the connecting frame 51. The motor drives the connecting frame 51 to rotate horizontally. The connecting frame 51 is L-shaped. When the brake disc 100 is in a vertical position after being flipped, the connecting frame 51 can rotate around the brake disc 100, thereby driving the laser 52 to remove rust from both sides of the brake disc 100. This eliminates the need for manual labor and increases efficiency. In other embodiments, the rust removal actuator 53 includes a motor and a gear. The output end of the motor is connected to the gear, and another gear is provided on the connecting frame 51. The gear on one side of the motor meshes with the gear on the connecting frame 51. The motor drives the gear to rotate, thereby causing the connecting frame 51 to rotate. Therefore, the specific structure of the rust removal actuator 53 is not limited, as long as it can achieve the above-mentioned functions.

[0083] Specifically, such as Figure 1 and Figure 9 As shown, the second grinding mechanism 6 includes a frustum 61, grinding elements 62, and a telescopic actuator 63. The frustum 61 is slidably connected to the support frame 1. Multiple grinding elements 62 are provided, spaced apart circumferentially along the frustum 61. A grinding head 621 is provided at the end of each grinding element 62 facing away from the frustum 61. The output end of the telescopic actuator 63 is connected to the frustum 61, enabling it to drive the frustum 61 to slide towards the first grinding mechanism 4. The sliding of the frustum 61 allows the grinding head 621 to extend into the stepped hole 102, thereby achieving the grinding operation of the stepped hole 102 without manual intervention, resulting in higher efficiency. Furthermore, the grinding head 621 in this embodiment is a pneumatic grinding head, which has a high rotational speed and good grinding quality. Its specific principle is clear to those skilled in the art and will not be elaborated further here.

[0084] More specifically, in this embodiment, the telescopic actuator 63 includes a motor, a gear, and a rack. The output shaft of the motor is connected to the gear, and the rack is meshed with the gear and connected to the frustum 61. The motor drives the gear to rotate around its own axis, thereby causing the rack and the frustum 61 to move synchronously in the horizontal direction. This allows the grinding head 621 on the frustum 61 to gradually approach the vertically positioned brake disc 100 until the grinding head 621 extends into the stepped hole 102 for grinding. In other embodiments, the telescopic actuator 63 includes a cylinder, the output end of which is connected to the frustum 61, thereby driving the frustum 61 to slide horizontally, resulting in smoother operation. In other words, the specific structure of the telescopic actuator 63 is not limited, as long as it can achieve the above-mentioned functions.

[0085] More specifically, such as Figure 1 , Figure 2 and Figure 9 As shown, to ensure more accurate and efficient grinding operations, the brake disc grinding device also includes a vision mechanism 7, which is mounted on the support frame 1. The vision mechanism 7 performs image recognition on the brake disc 100 to control its rotation angle, facilitating the insertion of the grinding head 621 into the stepped hole 102 for grinding, and the insertion of the grinding disc 42 into the keyway 101 for grinding. Furthermore, the vision mechanism 7 includes a camera and a computer. The camera captures images of the brake disc 100 and transmits the image information to the computer for image processing to calculate the rotation angle of the brake disc 100. The computer generates a control signal and transmits it to the rotary driver 34, which rotates the brake disc 100 so that the grinding head 621 is aligned with the stepped hole 102 on the brake disc 100, or the grinding disc 42 is aligned with the keyway 101, facilitating subsequent grinding operations. This not only improves grinding efficiency but also ensures the quality of the grinding operation. Furthermore, the vision mechanism 7 may also include photoelectric sensors, image processing units, controllers, etc., to facilitate image recognition and rotation angle control of the brake disc 100. That is, the specific structure of the vision mechanism 7 is not limited, as long as it can achieve the above-mentioned functions.

[0086] Specifically, such as Figure 9As shown, the second grinding mechanism 6 also includes an adjusting disk 64 and an adjusting driver 65. The adjusting disk 64 is rotatably connected to the frustum 61 and is concentrically arranged facing the frustum 61. The adjusting disk 64 has multiple sliding grooves 641, which are equally spaced along the circumference of the adjusting disk 64. The grinding part 62 is slidably connected to the frustum 61 along the radial direction. The end of the grinding part 62 away from the grinding head 621 has a protrusion 622, which extends into the sliding groove 641. The output end of the adjusting driver 65 is connected to the adjusting disk 64 and can drive the adjusting disk 64 to rotate. The rotation of the adjusting disk 64 can drive the sliding groove 641 to rotate. By pushing the protrusion 622 against the groove wall of the sliding groove 641, the grinding part 62 can be driven to slide along the radial direction of the adjusting disk 64, thereby adjusting the length of the grinding part 62 extending from the frustum 61, so that the grinding head 621 can adapt to different specifications of brake discs 100, so as to facilitate grinding operations and have wider adaptability.

[0087] More specifically, the extension directions of two adjacent slide grooves 641 are set at an angle, and the included angle between each pair of adjacent slide grooves 641 is the same. This ensures that the slide grooves 641 can simultaneously push against the protrusions 622 during rotation, thereby enabling multiple grinding parts 62 to slide simultaneously and extending multiple grinding heads 621 to the same length to accommodate the grinding of the stepped holes 102. Furthermore, the adjustment driver 65 in this embodiment can adopt a servo motor, stepper motor, or other structures, which will not be described in detail here.

[0088] The specific working process of this device is described below:

[0089] Step 1: The brake disc 100 is transported to the clamping station by the lifting and transporting mechanism 2. The clamping and flipping mechanism 3 clamps and fixes the brake disc 100 and drives the brake disc 100 to flip.

[0090] In step one above, the slide table 22 slides vertically until it is level with the clamping position on the clamping and flipping mechanism 3. The roller rotates to move the brake disc 100 until it is placed on the clamping position and remains horizontal. The clamping driver 38 drives the clamping member 37 to abut against the inner circumferential wall of the brake disc 100, thereby fixing the brake disc 100 and preventing it from shaking or falling. The flipping driver 32 drives the adapter 31 to rotate horizontally, thereby causing the turntable 33 and the brake disc 100 to flip 90 degrees, so that the brake disc 100 remains vertical.

[0091] Step 2: After the brake disc 100 is kept vertical, the sliding driver 43 drives the grinding disc 42 to extend into the keyway 101 for grinding. The brake disc 100 is rotated by rotating the driver 34 to complete the grinding operation of the remaining keyways 101.

[0092] In step two above, the vision mechanism 7 and the rotary driver 34 work together to ensure that the grinding disc 42 is precisely aligned with one of the keyways 101, thus guaranteeing the accuracy and precision of the operation. The sliding driver 43 drives the sliding plate 41 to slide horizontally, thereby causing the grinding disc 42 to extend into the keyway 101. In order for the grinding disc 42 to be precisely aligned into the keyway 101, the grinding cylinder drives the grinding disc 42 to grind up and down along the extension direction of the keyway 101, further improving the grinding quality. After the keyway 101 at that location is ground, the sliding driver 43 drives the grinding disc 42 to be pulled out of the keyway 101, and the rotary driver 34 drives the brake disc 100 to rotate to the next keyway 101, and repeats the above actions until all keyways 101 are ground.

[0093] Step 3: During the rotation of the brake disc 100, the laser 52 is driven to rotate by the rust removal driver 53 to remove rust from both sides of the brake disc 100.

[0094] In step three above, the brake disc 100 is driven to rotate horizontally by the drive driver 34. At the same time, the laser 52 removes rust from one side of the brake disc 100. The brake disc 100 is rotated while removing rust. After the rust removal on one side of the brake disc 100 is completed, the rust removal drive 53 drives the connecting frame 51 to rotate, which in turn drives the laser 52 to rotate horizontally, thereby removing rust from the other side of the brake disc 100. This allows the laser 52 to perform laser rust removal on both sides of the brake disc 100, resulting in higher work efficiency.

[0095] Step four: The rotation angle of the brake disc 100 is controlled by the vision mechanism 7, and the telescopic driver 63 drives the grinding head 621 to extend into the stepped hole 102 for grinding.

[0096] In step four above, when the brake disc 100 rotates until the stepped hole 102 is directly opposite the grinding head 621, the vision mechanism 7 controls the rotary driver 34 to stop the brake disc 100 from rotating. The telescopic driver 63 drives the truncated cone 61 to move toward the brake disc 100 until the grinding head 621 extends into the stepped hole 102 and performs grinding. After the stepped hole 102 at this location is ground, the telescopic driver 63 drives the grinding head 621 to retract from the stepped hole 102 to avoid interfering with the rotation of the brake disc 100. The rotary driver 34 drives the brake disc 100 to rotate horizontally again. When the vision mechanism 7 identifies the next batch of stepped holes 102 that need to be ground, it controls the rotary driver 34 to stop the rotation of the brake disc 100 and repeats the above actions until all stepped holes 102 are ground.

[0097] Step 5: The brake disc 100 is rotated to its initial state by the clamping and flipping mechanism 3, and the clamping and fixing of the brake disc 100 is released. The brake disc 100 is then transported out of the clamping station by the lifting and transporting mechanism 2.

[0098] It should be noted that the brake disc grinding device in this embodiment reduces the safety hazards such as falling and collision that exist in the reciprocating transport and high-frequency flipping of the brake disc 100. At the same time, the vision mechanism 7 enables precise positioning of the brake disc 100, thereby improving the efficiency of the grinding operation.
