Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, and in particular to an automatic suspended conveyor device for automotive parts processing. Background Technology

[0002] In the automated processing of automotive parts, automatic overhead conveyor systems are widely used as core equipment for material transfer, and are applied to the transport and temporary storage of workpieces between various processes. By suspending workpieces, this device can effectively utilize the upper space of the workshop, reduce ground occupation, and achieve continuous and stable transport of workpieces. It is an important guarantee for improving the automation level and operational efficiency of the production line.

[0003] Currently, existing automatic overhead conveyor systems typically consist of a suspension track, multiple fixed hooks, and a drive mechanism. Workpieces are manually or robotically hung on the hooks and then moved along the track by the drive system to complete the conveying between different workstations. Some devices have simple limiting protrusions or elastic buckles on the hooks to prevent the workpieces from shaking or accidentally falling off during the conveying process.

[0004] However, existing overhead conveyor devices still have significant shortcomings in practical applications. For automotive parts with perforated structures, traditional hooks can only provide simple suspension support and cannot effectively fix the workpiece. The workpiece is prone to rotation or displacement during the conveying process, affecting the positioning accuracy of subsequent processing. In addition, the spacing between multiple hooks is usually fixed and cannot be flexibly adjusted according to the workpiece size or processing requirements. Even if some devices have adjustment functions, the adjustment process is relatively cumbersome and cannot meet the needs of rapid switching in multi-variety, small-batch production modes.

[0005] Therefore, it is necessary to design an automatic suspended conveyor for processing automotive parts. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides an automatic suspended conveying device for processing automotive parts, which solves the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: An automatic suspended conveyor for processing automotive parts includes a suspension frame and multiple workpieces, and further includes: A mounting bracket installed on a suspension frame, wherein a receiving groove is provided in the mounting bracket and a mounting plate is slidably installed in the receiving groove, and multiple hooks are fixedly installed on the bottom of the mounting plate, and each hook is respectively engaged with a corresponding workpiece; A tensioning assembly installed on a hook is used to fix or relax a workpiece placed on the hook. The tensioning assembly includes multiple arc-shaped liners slidably mounted on the side wall of the hook. A lead screw is rotatably mounted inside the hook, and two sliding sleeves are threaded onto the lead screw. A connecting rod is installed between each of the two sliding sleeves and each arc-shaped liner. A fixed gear is fixedly mounted at one end of the lead screw outside the hook, and a fixed rack that meshes with the fixed gear is fixedly mounted at the bottom of the mounting frame.

[0008] Furthermore, a positioning ring is fixedly installed on the hook, and two sliding grooves that cooperate with the corresponding sliding sleeves are opened inside the hook. Multiple moving grooves are opened on the side walls of the two sliding grooves, and each moving groove cooperates with the corresponding connecting rod.

[0009] Furthermore, the mounting frame consists of a fixed block and multiple movable blocks. The fixed block is fixedly installed at the bottom of the suspension frame, and the multiple movable blocks are all installed on the suspension frame. A sliding rod is fixedly installed on the side wall of the fixed block, and a sliding groove that cooperates with the sliding rod is opened on the side wall of the movable block.

[0010] Furthermore, a motor is fixedly installed on the top of the fixed block, and a protrusion is fixedly installed on the top of each of the moving blocks. A threaded rod is fixedly connected to the output end of the motor, and the threaded rod is provided with multiple threaded segments. Each threaded segment is threadedly connected to the corresponding protrusion, and the length and pitch of the multiple threaded segments decrease sequentially from left to right.

[0011] Furthermore, the mounting plate consists of a mounting block and multiple sliding blocks. The mounting block is slidably disposed within a fixed block, and the multiple sliding blocks are slidably disposed within corresponding moving blocks.

[0012] Furthermore, a connecting rod is fixedly installed on the side wall of the mounting block, and a mating groove that mates with the connecting rod is provided on the side wall of the sliding block.

[0013] Furthermore, a lifting block is fixedly installed on the side wall of the mounting block, and a lifting groove that cooperates with the lifting block is opened on the side wall of the receiving groove. A second motor is fixedly installed on the top of the fixed block, and a screw is fixedly connected to the output end of the second motor. One end of the screw located in the lifting groove is threadedly connected to the lifting block.

[0014] Furthermore, a guide block is fixedly installed on the side wall of the movable block, a guide groove that mates with the guide block is opened on the side wall of the suspension frame, a connecting block is fixedly installed on the side wall of the arc-shaped liner, and a connecting groove that mates with the arc-shaped liner is opened on the side wall of the hook.

[0015] Compared with existing technologies, the advantages of this invention are: 1. Through the meshing of the fixed gear and the fixed rack, the screw can be automatically rotated as the hook moves with the mounting plate. Then, through the transmission of the sliding sleeve and the connecting rod, the arc-shaped liner is driven to expand outward or contract inward, realizing the automatic clamping and loosening of the inner hole of the workpiece. Reliable fixation of the workpiece with holes can be completed without an additional power source, effectively preventing the workpiece from rotating or shifting during the conveying process.

[0016] 2: By setting multiple threaded rods with different pitches, each moving block can move at different speeds and displacements, thereby enabling independent adjustment of the spacing between multiple hooks. This allows for flexible adaptation to the suspension requirements of workpieces of different sizes, improving the compatibility and rapid switching capability of the conveying device in multi-variety production modes.

[0017] In summary, this invention can automatically fix workpieces with holes, solving the problem that traditional hooks cannot be effectively positioned. At the same time, it can flexibly adjust the hook spacing to meet the conveying needs of workpieces of various sizes. It has a high degree of automation and strong adaptability, and significantly improves the suspension conveying effect of automotive parts. Attached Figure Description

[0020] Reference Figures 1-8 An automatic suspension conveyor for processing automotive parts includes a suspension frame 2 and multiple workpieces 1. The suspension frame 2 is used to connect with the output end of an existing automatic suspension conveyor to realize the transportation of workpieces 1 in the workshop. The specific connection method and the structure and working principle of the existing automatic suspension conveyor are not described in detail here.

[0021] The suspension frame 2 is equipped with a mounting frame 3. The mounting frame 3 has a receiving groove 4. The mounting plate 5 is slidably installed in the receiving groove 4. Multiple hooks 6 are fixedly installed at the bottom of the mounting plate 5. Each hook 6 is respectively engaged with the corresponding workpiece 1. The mounting plate 5 can slide up and down in the receiving groove 4.

[0022] The hook 6 is equipped with a tensioning component for fixing or loosening the workpiece 1 placed on the hook 6. Specifically, multiple arc-shaped liner plates 8 are slidably installed on the side wall of the hook 6, and connecting blocks 9 are fixedly installed on the side wall of the arc-shaped liner plates 8. A connecting groove 10 that mates with the connecting blocks 9 is opened on the side wall of the hook 6. Through the sliding engagement of the connecting blocks 9 and the connecting groove 10, the arc-shaped liner plates 8 can slide stably on the hook 6. A lead screw 11 is rotatably installed inside the hook 6. Two sliding sleeves 12 are threaded onto the lead screw 11. Each sliding sleeve 12 is hinged to a connecting rod 14 between itself and each arc-shaped liner 8. Two sliding grooves 13 are provided inside the hook 6 to cooperate with the corresponding sliding sleeves 12. The sliding grooves 13 are used to restrict the movement direction of the sliding sleeves 12, so that they can only slide along the axis of the lead screw 11. Multiple moving grooves 15 are provided on the side walls of the two sliding grooves 13. Each moving groove 15 cooperates with the corresponding connecting rod 14 to provide clearance space for the connecting rod 14 during the transmission process, avoid interference, and ensure the smoothness of the transmission process. A fixed gear 16 is fixedly installed at one end of the lead screw 11 outside the hook 6. A fixed rack 17 that meshes with the fixed gear 16 is fixedly installed at the bottom of the mounting frame 3. When the mounting plate 5 drives the hook 6 to move up and down relative to the mounting frame 3, the fixed gear 16 rolls along the fixed rack 17, driving the lead screw 11 to rotate, thereby driving the two sliding sleeves 12 to move towards or away from each other along the lead screw 11. Through the connecting rod 14, the arc-shaped liner 8 is pushed to expand outward or contract inward. When the mounting plate 5 moves down, the arc-shaped liner 8 expands outward and abuts against the inner wall of the workpiece 1, realizing automatic fixation of the workpiece 1. When the mounting plate 5 moves up, the arc-shaped liner 8 contracts inward and releases the workpiece 1, making it easy to remove and unload. With the above structure, the automatic clamping and releasing of the workpiece 1 can be realized without an additional power source, effectively preventing the workpiece 1 from rotating or shifting during the conveying process.

[0023] A positioning ring 7 is also fixedly installed on the hook 6 to limit the position of the workpiece 1 on the hook 6 and ensure that it effectively contacts the arc-shaped liner 8. When the workpiece 1 is hung on the hook 6, the back of the workpiece 1 abuts against the positioning ring 7 to ensure that the corresponding position of the arc-shaped liner 8 and the inner hole of the workpiece 1 is accurate, thereby improving the reliability of clamping and positioning.

[0024] The mounting frame 3 consists of a fixed block 301 and multiple movable blocks 302. The fixed block 301 is fixedly installed at the bottom of the suspension frame 2, and the multiple movable blocks 302 are slidably installed on the suspension frame 2. A sliding rod 303 is fixedly installed on the side wall of the fixed block 301, and a sliding groove that cooperates with the sliding rod 303 is opened on the side wall of the movable block 302. Through the cooperation between the sliding rod 303 and the sliding groove, the movable block 302 is stably guided to slide relative to the fixed block 301. A guide block 20 is also fixedly installed on the side wall of the movable block 302, and a guide groove 21 that cooperates with the guide block 20 is opened on the side wall of the suspension frame 2. Through the cooperation between the guide block 20 and the guide groove 21, the stability of the movable block 302 during the sliding process is further improved, ensuring the positional accuracy when adjusting the spacing of the hook 6.

[0025] A motor 18 is fixedly mounted on the top of the fixed block 301. A protrusion 304 is fixedly mounted on the top of each moving block 302. A threaded rod 19 is fixedly connected to the output end of the motor 18. The threaded rod 19 has multiple threaded segments, each of which is threadedly connected to the corresponding protrusion 304. The length and pitch of the multiple threaded segments decrease sequentially from left to right (see reference). Figure 2 When the motor 18 starts, the threaded rod 19 rotates. Due to the different pitches of each thread segment, each moving block 302 moves at different speeds and displacements under the drive of the protrusion 304, thereby realizing the independent adjustment of the spacing between multiple hooks 6 and the flexible adjustment of the overall layout. This structure can adapt to the suspension requirements of workpieces 1 of different sizes and meet the rapid switching of multi-variety, small-batch production modes.

[0026] The mounting plate 5 consists of a mounting block 501 and multiple sliding blocks 502. The mounting block 501 is slidably mounted up and down inside the fixed block 301, and the multiple sliding blocks 502 are respectively slidably mounted up and down inside the corresponding moving blocks 302. A connecting rod 503 is fixedly mounted on the side wall of the mounting block 501, and a mating groove that mates with the connecting rod 503 is opened on the side wall of the sliding block 502. When the moving block 302 moves relative to the fixed block 301, the connecting rod 503 is always inserted into the mating groove, ensuring that the mounting block 501 and each sliding block 502 maintain linkage, thereby realizing the synchronous lifting and lowering of multiple hooks 6.

[0027] A lifting block 23 is fixedly installed on the side wall of the mounting block 501. A lifting groove 24 that cooperates with the lifting block 23 is opened on the side wall of the receiving groove 4. A motor 22 is fixedly installed on the top of the fixing block 301. A screw 25 is fixedly connected to the output end of the motor 22. One end of the screw 25 located in the lifting groove 24 is threadedly connected to the lifting block 23. When the motor 22 starts, the screw 25 rotates, driving the lifting block 23 to move up and down along the lifting groove 24, thereby driving the mounting block 501 and multiple sliding blocks 502 to lift and lower synchronously, realizing the unified adjustment of the height of multiple hooks 6. This structure facilitates the centralized control of the height position of the workpiece 1 during the hanging and unloading process, simplifies the operation process, and improves the overall coordination and ease of use of the conveying device.

[0028] Both motor 18 and motor 22 can be ACM6004M2H servo motors. In addition, motor 18 and motor 22 can be connected to an existing PLC controller to control the operation of motor 18 and motor 22.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
