Description

Technical Field

[0001] This utility model belongs to the field of speed reducer manufacturing technology, and more specifically, it relates to an automatic assembly device for speed reducer gearboxes. Background Technology

[0002] Gearboxes, as core components of industrial transmission systems, are widely used in high-end equipment fields such as robot joint drives, wind power speed-increasing mechanisms, and new energy vehicle transmission systems. To meet the demands of precision assembly processes, the industry currently widely adopts intelligent robotic arms to perform gear gripping and positioning operations: using a vision-guided system to identify gears to be assembled at the end of the conveyor line, and utilizing the flexible control of a six-axis robotic arm to achieve millimeter-level precision assembly of the gearbox internals, significantly improving the assembly efficiency and operational reliability of the transmission system.

[0003] During automated gear conveying, the disordered arrangement of parts caused by vibration transmission results in a random distribution of gear rim teeth in three-dimensional space. After the intelligent robotic arm completes the gripping of the gear, it needs to perform multi-angle pose detection on the gripped gear through a vision system and trigger a multi-axis linkage mechanism to perform dynamic pose correction. This process requires computing resources above the edge computing unit level, and under long-term operation, it is easy to experience system response delays and computing resource overload. Utility Model Content

[0004] To address the issue that intelligent robotic arms require a vision system to continuously adjust the position of gears, this invention proposes an automatic assembly device for a reducer gearbox to overcome the aforementioned technical problems in existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an automatic assembly device for a reducer gearbox, including a transport frame, a transport component is provided inside the transport frame, a storage and positioning component is provided at one end of the transport component, an elastic compression component is provided on the upper side of the storage and positioning component, a drive component is provided inside the transport frame, the drive end of the drive component is connected to the storage and positioning component, and a push component is provided on both sides of the transport component.

[0007] The transport component is used to transport the gear, the push component is used to push the gear on the transport component onto the storage and positioning component, the elastic compression component is used to compress the gear on the storage and positioning component, and the drive component is used to drive the storage and positioning component to rotate so that the gear moves into the storage and positioning component under the push of the elastic push component.

[0008] Furthermore, the transport assembly includes transport rollers, several of which are rotatably connected inside the transport frame. A transport belt is provided on the outer surface of the transport rollers, and a positioning strip is fixedly connected to the outer surface of the transport belt. A transport motor is fixedly installed on the outer side of the transport frame, and the output end of the transport motor is fixedly connected to the transport rollers.

[0009] Furthermore, the storage and positioning component includes a positioning platform, which is disposed inside the transport frame. The top of the positioning platform has a positioning tooth groove and an arc-shaped positioning block. A guide frame is fixedly installed on the inner wall of the transport frame and is disposed between the transport belt and the positioning platform.

[0010] Furthermore, the elastic extrusion assembly includes a fixed frame, which is fixedly installed on the outside of the transport frame. A lifting hydraulic cylinder is fixedly installed on the top of the fixed frame. The output end of the lifting hydraulic cylinder passes through the fixed frame and is fixedly installed with a connecting plate. Several fixed rods are fixedly connected to the bottom of the connecting plate. A movable plate is movably connected to the outer surface of the fixed rods. An extrusion plate is fixedly connected to the bottom of the movable plate. A spring is fixedly connected between the connecting plate and the movable plate.

[0011] Furthermore, a connecting ring is fixedly connected to the bottom end of the fixed rod, the extrusion plate is movably connected to the connecting ring, and an arc-shaped limiting block is fixedly connected to the bottom of the connecting ring corresponding to the arc-shaped positioning block.

[0012] Furthermore, the drive assembly includes a mounting slot, which is located at the bottom of the transport frame. A support cylinder is fixedly connected to the bottom inner wall of the transport frame corresponding to the mounting slot. A positioning platform is located at the top of the support cylinder. A drive motor is fixedly installed at the top inner wall of the support cylinder. The output end of the drive motor is fixedly connected to the positioning platform. A connecting frame is fixedly connected to the outer side of the support cylinder. One end of the connecting frame is fixedly connected to the arc-shaped positioning block.

[0013] Furthermore, the pushing assembly includes a pushing belt disposed on the outside of the transport roller. A plurality of storage cylinders are fixedly connected to the outer surface of the pushing belt. A rotating shaft is rotatably connected inside the storage cylinder. The top end of the rotating shaft extends to the outside of the storage cylinder and is fixedly connected to a pushing plate. A torsion spring is fixedly connected between the rotating shaft and the storage cylinder.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model enables the gear to move directly into the storage and positioning component through the transport component and the pushing component. At the same time, when the storage and positioning component rotates and aligns with the gear vertically, the gear moves directly into the storage and positioning component under the push of the elastic compression component. Then, the storage and positioning component drives the gear to rotate to the predetermined position. This setting allows the gear teeth to maintain the same orientation when the intelligent robotic arm grasps the gear inside the storage and positioning component, thereby avoiding the phenomenon of system response delay and computing resource overload caused by the need for the grasped gear to be adjusted back and forth.

[0016] 2. This utility model uses a transport roller to make the push belt and the transport belt move synchronously. When the transport belt drives the gear to one side of the positioning table, the push plate on the push belt pushes the gear and pushes it to the top of the positioning table. When the gear comes into contact with the arc-shaped positioning block, the push plate begins to tilt. After the push plate passes through the positioning table, the torsion spring pulls the push plate through the rotating shaft, thereby making the push plate reset. Under the push of the push plate, the gear can move to the top of the positioning table better, and the push plate will not interfere with the overall operation of the device.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0029] Please see Figures 1-6 As shown, this utility model is an automatic assembly device for a reducer gearbox, including a transport frame 1, a transport component 2 is provided inside the transport frame 1, a storage and positioning component 3 is provided at one end of the transport component 2, an elastic compression component 4 is provided on the upper side of the storage and positioning component 3, a drive component 5 is provided inside the transport frame 1, the drive end of the drive component 5 is connected to the storage and positioning component 3, and push components 6 are provided on both sides of the transport component 2.

[0030] The transport component 2 is used to transport the gear, the push component 6 is used to push the gear on the transport component 2 onto the storage and positioning component 3, the elastic compression component 4 is used to compress the gear on the storage and positioning component 3, and the drive component 5 is used to drive the storage and positioning component 3 to rotate so that the gear moves into the interior of the storage and positioning component 3 under the push of the elastic push component 6.

[0031] After the gear is transported to one side of the storage and positioning component 3 by the transport component 2, the pushing component 6 pushes the gear and moves it directly to the top of the storage and positioning component 3. Then, the pressing end of the elastic pressing component 4 moves downward and presses the gear on the top of the storage and positioning component 3. Then, the driving component 5 drives the storage and positioning component 3 to rotate. When the storage and positioning component 3 and the gear are aligned vertically, the gear moves directly into the storage and positioning component 3 under the pressing of the elastic pressing component 4. At this time, the storage and positioning component 3 drives the gear to rotate together. When the storage and positioning component 3 rotates to the predetermined position, it stops rotating. When the gear is installed inside the gearbox, the intelligent robotic arm can grasp the gear inside the storage and positioning component 3.

[0032] The gear can be directly moved into the storage and positioning component 3 by means of the transport component 2 and the pushing component 6. At the same time, when the storage and positioning component 3 rotates and corresponds to the gear, the gear moves directly into the storage and positioning component 3 under the push of the elastic compression component 4. Then the storage and positioning component 3 drives the gear to rotate to the predetermined position. This setting allows the gear teeth to keep facing the same direction when the intelligent robotic arm grasps the gear inside the storage and positioning component 3, thereby avoiding the phenomenon of system response delay and computing resource overload caused by the need for the grasped gear to be adjusted back and forth.

[0033] In one embodiment, the transport component 2 includes a transport roller 201, several of which are rotatably connected inside the transport frame 1. A transport belt 202 is provided on the outer surface of the transport roller 201, and a positioning strip 203 is fixedly connected to the outer surface of the transport belt 202. A transport motor 204 is fixedly installed on the outer side of the transport frame 1, and the output end of the transport motor 204 is fixedly connected to the transport roller 201.

[0034] The transport motor 204 drives the transport roller 201, causing the transport roller 201 to move the transport belt 202 inside the transport frame 1. When installing the gears, several gears are placed on the transport belt 202 in sequence, so that the gears can move continuously towards the storage and positioning component 3 under the transport of the transport belt 202. Two positioning strips 203 are symmetrically arranged on the outer surface of the transport belt 202. When the transport belt 202 drives the gears to move, the positioning strips 203 can position the gears, so that the gears can move accurately into the storage and positioning component 3 under the drive of the transport belt 202.

[0035] In one embodiment, the storage and positioning component 3 includes a positioning platform 301, which is disposed inside the transport frame 1. The top of the positioning platform 301 is provided with a positioning tooth groove 302 and an arc-shaped positioning block 303. A guide frame 304 is fixedly installed on the inner wall of the transport frame 1 and is disposed between the transport belt 202 and the positioning platform 301.

[0036] After the gear moves to one side of the positioning platform 301, the pushing component 6 can push the gear, so that the gear moves directly to the top of the positioning platform 301 through the guide frame 304. When the gear comes into contact with the arc-shaped positioning block 303, the pushing component 6 can no longer push the gear. Since the guide frame 304 can support the gear as it moves from the conveyor belt 202 to the positioning platform 301, the gear is prevented from tilting. The arc-shaped positioning block 303 allows the gear to be directly collinear with the axis of the positioning tooth groove 302, so that when the positioning tooth groove 302 and the gear are aligned vertically, the gear can fall directly into the interior of the positioning tooth groove 302.

[0037] In one embodiment, the elastic extrusion assembly 4 includes a fixed frame 401, which is fixedly installed on the outside of the transport frame 1. A lifting hydraulic cylinder 402 is fixedly installed on the top of the fixed frame 401. The output end of the lifting hydraulic cylinder 402 passes through the fixed frame 401 and is fixedly installed with a connecting plate 403. A plurality of fixed rods 404 are fixedly connected to the bottom of the connecting plate 403. A movable plate 405 is movably connected to the outer surface of the fixed rods 404. An extrusion plate 406 is fixedly connected to the bottom of the movable plate 405. A spring 407 is fixedly connected between the connecting plate 403 and the movable plate 405.

[0038] After the gear moves to the top of the positioning platform 301, the lifting hydraulic cylinder 402 drives the connecting plate 403 to move downward. The moving connecting plate 403 drives the extrusion plate 406 to move downward through the fixed rod 404 and the spring 407, and extrudes the gear. Then the positioning platform 301 rotates. At this time, the gear will not rotate with the positioning platform 301 under the extrusion of the extrusion plate 406. When the positioning tooth groove 302 is aligned with the gear, the spring 407 extrudes the extrusion plate 406 downward, and the gear moves directly into the positioning tooth groove 302 under the extrusion of the extrusion plate 406. The spring 407 ensures that the extrusion plate 406 does not exert excessive pressure when extruding the gear. At the same time, when the positioning tooth groove 302 is aligned with the gear, the extrusion plate 406 can immediately extrude the gear into the positioning tooth groove 302.

[0039] In one embodiment, for the aforementioned fixed rod 404, a connecting ring 408 is fixedly connected to the bottom end of the fixed rod 404, the extrusion disc 406 is movably connected to the connecting ring 408, and an arc-shaped limiting block 409 is fixedly connected to the bottom of the connecting ring 408 corresponding to the arc-shaped positioning block 303.

[0040] The connecting plate 403 pushes the connecting ring 408 and the arc-shaped limiting block 409 downward through the fixing rod 404. When the pressing plate 406 comes into contact with the gear, it continues to push the connecting plate 403. At this time, the pressing plate 406 begins to move upward under the guidance of the fixing rod 404 and compresses the spring 407. When the arc-shaped limiting block 409 comes into contact with the top of the positioning table 301, the connecting plate 403 stops moving. At this time, the arc-shaped limiting block 409 and the arc-shaped positioning block 303 cooperate to limit the gear, so that when the positioning table 301 rotates, the gear will not disengage from the positioning table 301.

[0041] In one embodiment, the drive component 5 includes a mounting groove 501, which is located at the bottom of the transport frame 1. A support cylinder 502 is fixedly connected to the bottom of the inner wall of the transport frame 1 corresponding to the mounting groove 501. A positioning platform 301 is located at the top of the support cylinder 502. A drive motor 503 is fixedly installed at the top of the inner wall of the support cylinder 502. The output end of the drive motor 503 is fixedly connected to the positioning platform 301. A connecting frame 504 is fixedly connected to the outer side of the support cylinder 502. One end of the connecting frame 504 is fixedly connected to the arc-shaped positioning block 303.

[0042] The arc-shaped positioning block 303 can be connected to the support cylinder 502 via the connecting bracket 504. This arrangement ensures that the arc-shaped positioning block 303 will not rotate with the positioning table 301 when it rotates, thus guaranteeing the positioning effect of the arc-shaped positioning block 303. By driving the drive motor 503, the positioning table 301 is rotated on the top of the support cylinder 502. An encoder is installed at the output end of the drive motor 503, so that the drive motor 503 can automatically stop after rotating to a predetermined angle. The mounting slot 501 makes it convenient to disassemble the drive motor 503 installed inside the support cylinder 502.

[0043] In one embodiment, the pushing assembly 6 includes a pushing belt 601 disposed on the outside of the transport roller 201. A plurality of storage cylinders 602 are fixedly connected to the outer surface of the pushing belt 601. A rotating shaft 603 is rotatably connected inside the storage cylinders 602. The top end of the rotating shaft 603 extends to the outside of the storage cylinders 602 and is fixedly connected to a pushing plate 604. A torsion spring 605 is fixedly connected between the rotating shaft 603 and the storage cylinders 602.

[0044] Multiple push plates 604 are arranged in a curved array on the push belt 601. When the gear is placed on the conveyor belt 202, the gear can be brought into contact with the corresponding push plate 604. When the conveyor roller 201 drives the conveyor belt 202 to move and transport the gear, the push belt 601 moves synchronously with the conveyor belt 202 under the drive of the conveyor roller 201. This allows the push plates 604 on the conveyor belt 202 to move together with the gear. Since the conveyor belt 202 is longer than the push belt 601, when the conveyor belt 202 drives the gear to one side of the positioning table 301, the push plates 604 on the push belt 601 can move the gear. The push plate 604 is pushed so that the gear can move normally to the top of the positioning platform 301. When the gear comes into contact with the arc-shaped positioning block 303, the push plate 604 can no longer push the gear. At this time, the push plate 604 starts to drive the rotating shaft 603 to rotate inside the storage cylinder 602, so that the push plate 604 can tilt. After the push plate 604 passes through the positioning platform 301, the torsion spring 605 pulls the rotating shaft 603, so that the rotating shaft 603 drives the push plate 604 to reset. The above settings allow the gear to move to the top of the positioning platform 301 better, and the push plate 604 will not obstruct the movement of the push belt 601.

[0045] Through the above technical solution, 1. The transport component 2 and the pushing component 6 allow the gear to move directly into the storage and positioning component 3. Simultaneously, when the storage and positioning component 3 rotates and aligns with the gear vertically, the gear, pushed by the elastic compression component 4, moves directly into the storage and positioning component 3. Then, the storage and positioning component 3 drives the gear to rotate to a predetermined position. This configuration ensures that when the intelligent robotic arm grasps the gear inside the storage and positioning component 3, the gear teeth maintain a consistent orientation, thus avoiding the need for the grasped gear to be adjusted back and forth, which would lead to system response delays and computational resource overload; 2. The transport roller 201 allows the pushing belt 6 to... 01 moves synchronously with the conveyor belt 202. When the conveyor belt 202 drives the gear to one side of the positioning platform 301, the push plate 604 on the push belt 601 pushes the gear and pushes it to the top of the positioning platform 301. When the gear comes into contact with the arc-shaped positioning block 303, the push plate 604 begins to tilt. After the push plate 604 passes through the positioning platform 301, the torsion spring 605 pulls the push plate 604 through the rotating shaft 603, thereby resetting the push plate 604. Under the push of the push plate 604, the gear can move to the top of the positioning platform 301 more effectively, and the push plate 604 will not interfere with the overall operation of the device.
