Description

Technical Field

[0001] This invention relates to the field of AGV technology, and in particular to a transfer device for processing excavator bucket teeth. Background Technology

[0002] Excavator bucket teeth are detachable, wear-resistant parts that come into direct contact with the working medium (such as soil, rock, ore, etc.) at the front end of the excavator bucket. They are core wear parts in excavation operations. As the "cutting edge" of the bucket, they crush and peel away the working object through their sharp tooth structure, reducing digging resistance and protecting the bucket body from direct wear, extending the service life of the bucket and reducing the overall maintenance cost of the machine.

[0003] In the prior art, Chinese Patent No. CN211945068U proposes an AGV transfer machine to solve the technical problem that restricts the movement of AGVs when docking with existing production line docking mechanisms. This AGV transfer machine includes a conveying mechanism, a drive mechanism, and a support frame. The conveying mechanism and the drive mechanism are spaced apart to allow the AGV to move between them. The support frame is connected to the end of the drive mechanism closest to the conveying mechanism and can move towards or away from the conveying mechanism under the drive of the drive mechanism. The spaced arrangement of the conveying mechanism and drive mechanism allows the AGV to rotate within the interval to adjust the unloading angle of the material, resulting in unrestricted movement and more flexible unloading.

[0004] Regarding the aforementioned and existing related technologies, the inventors believe that the following defects often exist: In the production and transfer of excavator bucket teeth, AGVs often undertake the task of transferring raw materials for the bucket teeth. These raw materials are typically placed in batches in dedicated transfer boxes. The AGV can autonomously travel within a preset operating range to the bottom of the transfer box and automatically transfer the entire box using its lifting mechanism. However, in actual applications, when the transfer box is placed on the ground, it may experience slight tilting due to factors such as insufficient ground flatness, human error during placement, or uneven force on the bottom support points of the transfer box. This slight tilting is often difficult to detect visually. When a slightly tilted transfer box is lifted by the AGV, its center of gravity will deviate from the lifting center. As the AGV moves, its steering, acceleration, and deceleration further amplify this shift, easily causing the transfer box to lose balance and tip over, affecting the stability and safety of the transfer process. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that if the transfer box is slightly tilted on the ground during the transfer process, it may be difficult to detect and may cause the transfer box to tip over, affecting the safety of the transfer. To this end, we propose a transfer device for processing excavator bucket teeth.

[0006] To achieve the above objectives, this application adopts the following technical solution: a transfer device for processing excavator bucket teeth, comprising an AGV body and a lifting plate disposed on the top surface of the AGV body. Two slots are symmetrically formed on the top surface of the AGV body. Two spring telescopic rods are symmetrically fixedly installed at both ends of the inner bottom surface of each slot. A guide frame is fixedly installed at the top of each of the two spring telescopic rods. A positioning arm is slidably installed on the inner wall of the guide frame. A clamping plate is rotatably installed at one end of the positioning arm via a pivot shaft and a torsion spring. A reset structure corresponding to the clamping plate is provided on the side of the AGV body. A transmission plate is fixedly installed at the end of the positioning arm away from the clamping plate. A spring is fixedly installed between the opposite sides of the two transmission plates. Two sets of guide structures corresponding to the four transmission plates are provided on the top surface of the AGV body. Two sets of drive structures corresponding to the slots are provided on the inner side of the AGV body. A monitoring support assembly is provided on the outer wall of the positioning arm.

[0007] Preferably, a protective sleeve corresponding to the spring is fixedly installed on the side of the transmission plate.

[0008] Preferably, the guide structure includes a fixed plate fixedly installed on the top surface of the AGV body at the slotted side position, two U-shaped guide grooves are symmetrically opened on the side of the fixed plate, two inclined grooves are symmetrically opened on the side of the fixed plate respectively communicating with the two U-shaped guide grooves, and a guide rod is fixedly installed on the side of the transmission plate.

[0009] Preferably, the side of the fixing plate is in contact with the side of the transmission plate, and the outer wall of the guide rod is in contact with the inner wall of the U-shaped guide groove and the inclined groove.

[0010] Preferably, the drive structure includes a drive screw rotatably mounted on the inner wall of the slot, an inner cavity is provided on the inner side of the AGV body, one end of the drive screw passes through the inner wall of the inner cavity and is located inside the inner cavity, a servo motor is fixedly mounted on the inner bottom surface of the inner cavity, and the output end of the servo motor is connected to the end of the drive screw through a driven wheel and a synchronous belt.

[0011] Preferably, the threads on both sides of the outer wall of the drive screw are in opposite directions, and the bottom end of the transmission plate is screwed to the outer wall of the drive screw.

[0012] Preferably, the reset structure includes a limiting rod fixedly installed on the inner wall of the end of the positioning arm and corresponding to the clamping plate. The side of the AGV body is provided with an installation groove. A top rod is slidably installed on the inner wall of the installation groove. A spring is fixedly installed between the end of the top rod and the inner wall of the installation groove.

[0013] Preferably, the monitoring support assembly includes a groove formed on the top surface of the positioning arm. A support shell is rotatably mounted on the inner wall of the groove via a second rotating shaft and a second torsion spring. A support plate is slidably mounted on the inner wall of the support shell. A spring is fixedly mounted between the end of the support plate and the inner wall of the support shell. Two push rods are symmetrically fixedly mounted on one end of the support plate located inside the support shell, and the ends of the push rods pass through the side of the support shell. A shaft corresponding to the vertical state of the push rods is rotatably mounted on the inner wall of the groove. A torsion spring is fitted onto the end of the shaft, and the two ends of the torsion spring are fixedly connected to the groove and the shaft, respectively. A limit plate is fixedly mounted on the outer wall of the shaft.

[0014] Preferably, the bottom surface of the positioning arm is provided with a connecting groove that communicates with the receiving groove. The inner wall of the connecting groove is rotatably mounted with a support leg via a pivot shaft and a torsion spring. The end of the support leg is rotatably mounted with a support wheel, and the top surface of the support leg is fixedly mounted with a buckle plate corresponding to the limiting plate.

[0015] Preferably, the bottom surface of the limiting plate and the top surface of the buckle plate are both set as corresponding inclined surfaces.

[0016] The technical effects and advantages of this invention are as follows: In this invention, after the AGV lifts the transfer box, the positioning arm automatically extends and the clamping plate rotates 90 degrees. The servo motor drives the bidirectional threaded drive screw, which drives the positioning arm to move towards each other, accurately clamping the transfer box and aligning it to the center position of the lifting plate. This solves the problem of center of gravity shift caused by the initial skewed placement of the transfer box, ensures that the transfer box is subjected to balanced force, reduces the risk of tipping over from the root, and lays the foundation for stable transfer in the future. In this invention, during the transfer process, the clamping plate continuously and firmly clamps the transfer box, forming the first line of defense against tipping over. If the transfer box accidentally tilts to the side, the support shell automatically unfolds to support it. The tilting pressure triggers the outriggers to pop out and contact the ground, forming the second line of emergency support. The dual protective structures work together to resist the influence of external forces such as bumps and turns during driving, greatly reducing the probability of the transfer box tipping over and significantly improving operational safety. In this invention, after the transfer is completed, the lifting plate is raised to separate the transfer box from the clamping plate, and the positioning arm is reset under the action of the drive screw. During the process, the clamping plate, support shell, and support legs can be automatically flipped and stored in the corresponding slots without manual intervention. After each component is reset, it can quickly enter the next round of transfer preparation state, which not only avoids the impact of exposed components on equipment movement, but also saves manual sorting steps, ensuring the continuity and efficiency of the transfer operation.

[0019] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0020] Reference Figures 1 to 9As shown, the present invention provides a technical solution: a transfer device for processing excavator bucket teeth, including an AGV body 11 and a lifting plate 12 disposed on the top surface of the AGV body 11. Two slots 13 are symmetrically opened on the top surface of the AGV body 11. Two spring telescopic rods 21 are symmetrically fixedly installed at both ends of the inner bottom surface of the slots 13. Guide frames 22 are fixedly installed at the top ends of the two spring telescopic rods 21. Positioning arms 23 are slidably installed on the inner wall of the guide frames 22. A clamping plate 51 is rotatably installed at one end of the positioning arm 23 through a rotating shaft and a torsion spring. A transmission plate 24 is fixedly installed at the end of the positioning arm 23 away from the clamping plate 51. A spring 25 is fixedly installed between the opposite sides of the two transmission plates 24. A protective sleeve 26 corresponding to the spring 25 is fixedly installed on the side of the transmission plate 24.

[0021] In use, the raw materials for the excavator bucket teeth are placed in the transfer box, which is placed in the loading area of ​​the AGV body 11. During transfer, the AGV body 11 can be moved directly under the transfer box, and then the lifting plate 12 can be raised to lift the transfer box off the ground. When the transfer box is lifted by the lifting plate 12, the lifting plate 12 separates from the guide frame 22, releasing the restriction on the guide frame 22. At this time, under the support of the spring telescopic rod 21, the guide frame 22 and the positioning arm 23 move upward, and the transmission plate 24 separates from the drive screw 41, releasing the restriction on the positioning arm 23. Under the action of the spring 25, the two positioning arms 23 located on the same side can move in a direction away from each other, so that the positioning arm 23 extends out of the AGV body 11.

[0022] Reference Figures 3 to 5 As shown, the top surface of the AGV body 11 is provided with two sets of guide structures corresponding to the four transmission plates 24. The guide structure includes a fixed plate 31 fixedly installed on the top surface of the AGV body 11 at the side of the slot 13. The side of the fixed plate 31 is in contact with the side of the transmission plate 24. Two U-shaped guide grooves 32 are symmetrically opened on the side of the fixed plate 31. Two inclined grooves 33 are symmetrically opened on the side of the fixed plate 31, which are respectively connected to the two U-shaped guide grooves 32. A guide rod 34 is fixedly installed on the side of the transmission plate 24. The outer wall of the guide rod 34 is in contact with the inner wall of the U-shaped guide groove 32 and the inclined groove 33. The inner side of the AGV body 11 is provided with two sets of drive structures corresponding to the slot 13. The drive structure includes a drive screw 41 rotatably installed on the inner wall of the slot 13. The threads on both sides of the outer wall of the drive screw 41 are opposite. The bottom end of the transmission plate 24 is screwed to the outer wall of the drive screw 41. The inner side of the AGV body 11 is provided with an inner cavity 42. One end of the drive screw 41 passes through the inner wall of the inner cavity 42 and is located inside the inner cavity 42. A servo motor 43 is fixedly installed on the inner bottom surface of the inner cavity 42. The output end of the servo motor 43 is connected to the end of the drive screw 41 through a driven wheel and a synchronous belt.

[0023] During the upward movement and extension of the positioning arm 23, the guide rod 34 on the side of the transmission plate 24 can slide along the U-shaped guide groove 32, and at the extended end, the guide rod 34 can slide along the inclined groove 33 into the bottom of the U-shaped guide groove 32, thereby causing the transmission plate 24, the positioning arm 23, and the guide frame 22 to move downward and compress the spring telescopic rod 21. The transmission plate 24 is then screwed into the drive screw 41 again. During the extension of the positioning arm 23, the clamping plate 51 at its end can extend out of the coverage area of ​​the transfer box. At this time, under the action of the first rotating shaft and the first torsion spring, the clamping plate 51 can rotate 90 degrees. At this time, the transmission plate 24 is screwed into the drive screw 41, which can open the servo motor 43 in the inner cavity 42 to drive the drive screw 41 to rotate through the driven wheel and the synchronous belt. The threads on both sides of the outer wall of the drive screw 41 are in opposite directions. The transmission plate 24 is screwed into the drive screw 41, and the positioning arm 23 is screwed into the guide. The frame 22 is slidably connected, so when the drive screw 41 rotates, it can drive the two positioning arms 23 to slide towards each other, so that the rotating clamping plate 51 can clamp the transfer box on the top surface of the lifting plate 12 to straighten the transfer box and make it located at the center of the top surface of the lifting plate 12. At the same time, during the transfer process, the clamping of the clamping plate 51 can reinforce the transfer box, reduce the probability of it tipping over, and increase the safety of the transfer. When the positioning arm 23 is reset, the guide rod 34 can enter the corner above the end of the U-shaped guide groove 32, the lifting plate 12 descends and resets, and the transfer box separates from the lifting plate 12, thus completing the transfer of the excavator bucket teeth. During the downward movement of the lifting plate 12, the guide frame 22 can be pressed, so that the guide rod 34 enters the corner below the end of the U-shaped groove and resets, so that the above steps can be repeated to continue the transfer.

[0024] Reference Figures 4 to 6 As shown, the side of the AGV body 11 is provided with a reset structure corresponding to the clamping plate 51. The reset structure includes a limiting rod 52 fixedly installed on the inner wall of the end of the positioning arm 23 and corresponding to the clamping plate 51. The side of the AGV body 11 is provided with an installation groove 53. A top rod 54 is slidably installed on the inner wall of the installation groove 53. A spring 55 is fixedly installed between the end of the top rod 54 and the inner wall of the installation groove 53.

[0025] After rotating 90 degrees, the clamping plate 51 can contact the push rod 54 in the mounting groove 53. As the positioning arm 23 moves, the push rod 54 can push the bottom end of the clamping plate 51, causing the clamping plate 51 to rotate 90 degrees and reset. Then, as the positioning arm 23 resets, the clamping plate 51 can drive the push rod 54 to move into the mounting groove 53 and compress the second spring 55 so that it can be used again when the positioning arm 23 is unfolded.

[0026] Reference Figures 6 to 9As shown, the outer wall of the positioning arm 23 is provided with a monitoring support assembly. The monitoring support assembly includes a groove 61 opened on the top surface of the positioning arm 23. A support shell 62 is rotatably installed on the inner wall of the groove 61 through a pivot shaft and a torsion spring. A support plate 63 is slidably installed on the inner wall of the support shell 62. A spring 64 is fixedly installed between the end of the support plate 63 and the inner wall of the support shell 62. Two push rods 65 are symmetrically fixedly installed on one end of the support plate 63 located inside the support shell 62, and the ends of the push rods 65 pass through the side of the support shell 62. A shaft 66 corresponding to the vertical state of the push rods 65 is rotatably installed on the inner wall of the groove 61. A torsion spring 67 is fitted on the end of the shaft 66, and the two ends of the torsion spring 67 are fixedly connected to the groove 61 and the shaft 66 respectively. A limit plate 68 is fixedly installed on the outer wall of the shaft 66. The bottom surface of the positioning arm 23 is provided with a connecting groove 71 that communicates with the receiving groove 61. The inner wall of the connecting groove 71 is rotatably mounted with a support leg 72 via a rotating shaft three and a torsion spring three. The end of the support leg 72 is rotatably mounted with a support wheel 74. The top surface of the support leg 72 is fixedly mounted with a buckle plate 73 corresponding to the limiting plate 68. The bottom surface of the limiting plate 68 and the top surface of the buckle plate 73 are both set as corresponding inclined surfaces.

[0027] During the extension of the positioning arm 23, the support shell 62 in the trough 61 can be released from its limit and rotate 90 degrees to a vertical position under the action of the second rotating shaft and the second torsion spring. The top of the support plate 63 on the inner wall of the support shell 62 can fit against the bottom surface of the transfer box. If the transfer box tilts during the transfer process, the bottom surface of the tilted side of the transfer box will push the support plate 63, causing the support plate 63 and the push rod 65 to move downward. At this time, the buckle plate 73 on the top surface of the support leg 72 overlaps with the limiting plate 68 on the outer wall of the shaft 66. Under the pushing action of the push rod 65, the shaft 66 and the limiting plate 68 can rotate, causing the buckle plate 73 to separate from the limiting plate 68, thus releasing the limit on the support leg 72. Under the action of the third rotating shaft and the third torsion spring, the support leg 72 pops out of the connecting groove 71. In a vertical position, with the support wheel 74 in contact with the ground, the transfer box is further supported, ensuring safety during the transfer process. When the AGV body 11 transfers the transfer box containing the excavator bucket teeth to the corresponding position, the lifting plate 12 can be raised first to separate the transfer box from the clamping plate 51. Then, the servo motor 43 is turned on to drive the drive screw 41 to rotate, causing the two positioning arms 23 to move closer to each other for resetting. During the resetting process of the positioning arms 23, when the support shell 62 contacts the guide frame 22, the support shell 62 can rotate into the receiving groove 61 under the action of the guide frame 22. Then, when the outrigger 72 contacts the AGV body 11 and the guide frame 22, it can rotate into the connecting groove 71 for storage.

[0028] Working principle: During use, the raw materials for the excavator bucket teeth are placed in the transfer box, which is placed in the loading area of ​​the AGV body 11. During transfer, the AGV body 11 can move directly under the transfer box, and then the lifting plate 12 is raised to lift the transfer box off the ground. When the transfer box is lifted by the lifting plate 12, the lifting plate 12 separates from the guide frame 22, releasing the restriction on the guide frame 22. At this time, under the support of the spring telescopic rod 21, the guide frame 22 and the positioning arm 23 move upward, and the transmission plate 24 separates from the drive screw 41, releasing the restriction on the positioning arm 23. Under the action of spring 25, the two positioning arms 23 located on the same side can move away from each other, so that the positioning arms 23 extend out of the AGV body 11. During the upward movement and extension of the positioning arms 23, the guide rod 34 on the side of the transmission plate 24 can slide along the U-shaped guide groove 32, and at the end of the extension, the guide rod 34 can slide along the inclined groove 33 into the bottom of the U-shaped guide groove 32, thereby causing the transmission plate 24, the positioning arms 23 and the guide frame 22 to move downward and compress the spring telescopic rod 21. The transmission plate 24 is screwed to the drive screw 41 again. During the extension of the positioning arm 23, the clamping plate 51 at its end can extend beyond the coverage area of ​​the transfer box. At this time, under the action of the rotating shaft and the torsion spring, the clamping plate 51 can rotate 90 degrees, and under the action of the limiting rod 52, the clamping plate 51 can be fixed at the 90-degree position. At this time, the transmission plate 24 is screwed to the drive screw 41, which can open the servo motor 43 in the inner cavity 42 to drive the drive screw 41 to rotate through the driven wheel and the synchronous belt. The threads on both sides of the outer wall of the drive screw 41 are in opposite directions. The transmission plate 24 and the drive screw 41 are screwed together. The rod 41 is screwed in, and the positioning arm 23 is slidably connected to the guide frame 22. Therefore, when the drive screw 41 rotates, it can drive the two positioning arms 23 to slide towards each other, so that the rotating clamping plate 51 can clamp the transfer box on the top surface of the lifting plate 12 to straighten the transfer box and make the transfer box located at the center of the top surface of the lifting plate 12. At the same time, during the transfer process, the clamping of the clamping plate 51 can reinforce the transfer box, reduce the probability of it tipping over, and increase the safety of the transfer. During the extension of the positioning arm 23, the support shell 62 in the trough 61 can be released from its limit and rotate 90 degrees to a vertical position under the action of the second rotating shaft and the second torsion spring. The top of the support plate 63 on the inner wall of the support shell 62 can fit against the bottom surface of the transfer box. If the transfer box tilts during the transfer process, the bottom surface of the tilted side of the transfer box will push the support plate 63, causing the support plate 63 and the push rod 65 to move downward. At this time, the buckle plate 73 on the top surface of the support leg 72 overlaps with the limiting plate 68 on the outer wall of the shaft 66. Under the pushing action of the push rod 65, the shaft 66 and the limiting plate 68 can rotate, causing the buckle plate 73 to separate from the limiting plate 68, thereby releasing the limit on the support leg 72. Under the action of the third rotating shaft and the third torsion spring, the support leg 72 pops out of the connecting groove 71 and is in a vertical position, and the support wheel 74 contacts the ground, thereby providing further support for the transfer box and further ensuring the safety of the transfer box during the transfer process. When the AGV body 11 transports the transfer box containing the excavator bucket teeth to the corresponding position, the lifting plate 12 can be raised first to separate the transfer box from the clamping plate 51. Then, the servo motor 43 is turned on to drive the drive screw 41 to rotate, causing the two positioning arms 23 to move closer to each other and reset. During the reset process of the positioning arms 23, when the support shell 62 contacts the guide frame 22, the support shell 62 can rotate into the receiving groove 61 under the action of the guide frame 22. Then, when the outrigger 72 contacts the AGV body 11 and the guide frame 22, it can rotate into the connecting groove 71 for storage. At the same time, the clamping plate 51, after rotating 90 degrees, can contact the top rod 54 in the mounting groove 53. As the positioning arm 23 moves, the top rod... 54 can push the bottom end of the clamping plate 51, causing the clamping plate 51 to rotate 90 degrees and reset. Then, as the positioning arm 23 resets, the clamping plate 51 can drive the top rod 54 to move into the mounting groove 53 and compress the spring 2 55 so that it can be used again when the positioning arm 23 is unfolded. When the positioning arm 23 is reset, the guide rod 34 can enter the corner above the end of the U-shaped guide groove 32, the lifting plate 12 descends and resets, and the transfer box separates from the lifting plate 12, thus completing the transfer of the excavator bucket teeth. During the process of the lifting plate 12 moving down, the guide frame 22 can be pressed, causing the guide rod 34 to enter the corner position below the end of the U-shaped groove and reset, so that the above steps can be repeated to continue the transfer.

[0029] The technical scope of this invention is not limited to the content described above.
