Description

Technical Field

[0001] This invention relates to the field of bearing manufacturing technology, and in particular to a bearing manufacturing conveying device. Background Technology

[0002] In modern industrial production, bearings, as core components of mechanical transmission systems, directly impact the performance and manufacturing costs of various mechanical products through their production quality and efficiency. With the continuous improvement of automation levels in manufacturing, the conveying and assembly stages in bearing production have gradually become key bottlenecks restricting production efficiency. Traditional bearing production conveying methods rely heavily on manual assistance or semi-automated equipment, resulting in low conveying efficiency, insufficient positioning accuracy, and high labor intensity, making it difficult to meet the demands of large-scale, high-precision production.

[0003] Currently, bearing production conveying devices generally face the following technical challenges: First, bearing workpieces are prone to posture deviation or jamming during conveying, especially small bearing components. Due to their small size and precise structure, traditional conveying channels cannot achieve stable and orderly feeding, resulting in additional correction time required for subsequent assembly processes, which seriously affects the production cycle. Second, existing conveying devices lack flexibility and cannot adapt to the rapid switching of production for different bearing models. When changing molds or adjusting positioning parameters, the machine must be stopped, resulting in low equipment uptime. Third, bearing workpieces lack an effective buffer protection mechanism at the unloading stage at the end of the conveying process. Workpieces falling at high speed are prone to surface scratches or structural damage due to collisions, reducing the product qualification rate.

[0004] Therefore, a bearing production and conveying device needs to be designed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bearing production conveying device.

[0016] 1.

It can stably position and clamp bearings of different sizes, and can quickly switch production without stopping the machine, improving equipment uptime and meeting diversified production needs.

[0018] 3. Compared with existing technologies, by using electromagnets and multiple staggered connecting rods, the appropriate number of arc blocks can be precisely controlled to enter the arc opening when adjusting the size of the space inside the arc opening. This ensures that unused arc blocks are not located above the arc opening, effectively avoiding any impact on subsequent bearing processing. This ensures the stability and accuracy of the assembly process, reduces human error, and improves the degree of automation integration and the stability of production quality.

[0019] 4. Compared with existing technologies, the impact-reducing component at the lower end of the feeding plate effectively solves the problem of collision damage during bearing workpiece feeding. The coordinated operation of the vertical plate, rotating block, receiving platform, gear rack, and other structures, combined with the elastic buffer of the fourth spring, allows the bearing to enter the collection frame at a lower height, providing reliable protection for the bearing. Simultaneously, the impact-reducing component can rotate under external force, avoiding any impact on the placement and handling of the collection frame, improving operational convenience, and further increasing the product qualification rate.

[0020] In summary, by setting up assembly components and impact reduction components, this invention effectively solves the problems of low efficiency, insufficient precision, easy product damage, and low automation in existing bearing production and conveying devices. It realizes high efficiency, precision, flexibility, and intelligence in the entire bearing production process, significantly improving production efficiency and product quality, and has high practical value and promotion prospects.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] Reference Figure 1-Figure 5 A bearing production conveying device includes a frame 1, which serves as the basic support structure for the entire device and provides a stable installation platform for each component. A vibrating feeding plate 2 and a worktable 20 are installed on the upper end of the frame 1. The vibrating feeding plate 2 is used to realize the automatic feeding and orderly arrangement of bearings. A conveying channel 4 is fixedly connected to the upper end of the worktable 20. The conveying channel 4 is U-shaped and has an opening on the front side. This opening design facilitates the subsequent conveying components to grasp and convey the bearings. The conveying channel 4 is connected to the discharge port of the vibrating feeding plate 2 to ensure that the bearings discharged from the vibrating feeding plate 2 can smoothly enter the conveying channel 4. A conveying component is installed on the upper end of the worktable 20.

[0029] The conveying assembly is equipped with multiple assembly components for adaptive adjustment according to the bearing size to achieve stable clamping. Each assembly component includes a fixed frame 23 and an L-shaped block 16. Multiple vertical rods 27 are slidably connected through the fixed frame 23. A rectangular block 24 is fixedly connected to the upper end of each vertical rod 27. Each rectangular block 24 is elastically connected to the adjacent side of the fixed frame 23 via two first springs 26. The first springs 26 provide an upward elastic restoring force to the rectangular block 24 and the vertical rod 27. Each vertical rod 27 has a vertical groove 28 on its right side. Each vertical groove 28 is slidably connected to a sliding L-rod 30, which can slide up and down along the vertical groove 28. Each sliding L-rod 30 is elastically connected to the inner top of the corresponding vertical groove 28 by a second spring 29. The second spring 29 provides a downward elastic driving force for the sliding L-rod 30. Each sliding L-rod 30 has a moving groove 31 on its rear side, and each moving groove 31 is slidably connected to a connecting rod 32, which can slide back and forth in the moving groove 31. Each connecting rod 32 is fixedly connected to an arc-shaped block 22 at its lower end.

[0030] The spacing between adjacent bearings of the vibrating feeding plate 2 is the same as the spacing between the two arc-shaped openings 21 on each mold plate 14. The inner diameter of the arc-shaped block 22 decreases from front to back, and the outer diameter of each arc-shaped block 22 is the same as the inner diameter of the previous arc-shaped block 22. At the same time, the outer diameter of the foremost arc-shaped block 22 is the same as the radius of the arc-shaped opening 21.

[0031] Two third pneumatic rods 17 are fixedly connected to the rear side of the L-shaped block 16. The telescopic ends of the two third pneumatic rods 17 are fixedly connected to a strip plate 19. Multiple abutments 18 are fixedly connected to the rear side of the strip plate 19. The rear side of the abutment 18 is an arc surface. The extension and retraction of the third pneumatic rods 17 drives the strip plate 19 and the abutment 18 to move back and forth, thereby pushing the rectangular block 24 and realizing the downward movement of the vertical rod 27.

[0032] Each connecting rod 32 is elastically connected to the inner wall of the corresponding moving groove 31 by a third spring 33. An electromagnet 34 is embedded in the inner wall of the front moving groove 31. The rectangular block 24 and the adjacent sides of the fixed frame 23 are fixedly connected with mutually cooperating contact blocks 25. The frame 1 is equipped with a control switch and a power supply. The control switch, the power supply, the two contact blocks 25 and the electromagnet 34 form a circuit through wires. When the two contact blocks 25 are in contact, the multiple abutments 18 move to the designated position. After pressing the control switch, the circuit is turned on, the electromagnet 34 is energized and generates magnetic force, which generates a repulsive force on the connecting rod 32 on the front side, causing the connecting rod 32 to drive the corresponding arc block 22 to move backward.

[0033] The conveying assembly includes a U-shaped frame 5 mounted on the upper end of the workbench 20. Two first slide rails 6 are fixedly connected to the upper end of the U-shaped frame 5. First sliders 8 are slidably connected to both first slide rails 6. A movable disk 9 is fixedly connected to the upper end of both first sliders 8. The first sliders 8 are driven to slide along the first slide rails 6 by the extension and retraction of the first pneumatic rods 7, thereby driving the movable disk 9 to reciprocate in the left and right directions. Two first pneumatic rods 7 are fixedly connected to the inner right side of the U-shaped frame 5. The extension and retraction ends of the two first pneumatic rods 7 are fixedly connected to the corresponding first sliders 8. Two second slide rails are fixedly connected to the movable disk 9. Second sliders 12 are slidably connected to both second slide rails. An L-shaped fixing steel 13 is fixedly connected to the rear side of both second sliders 12. Two mold plates 14 are fixedly connected to the upper end of the L-shaped fixing steel 13. Two arc-shaped openings 21 are provided on the rear side of both mold plates 14. The arc-shaped openings 21 are adapted to the shape of the largest bearing.

[0034] A fixed block 11 is fixedly connected to the upper end of the movable disk 9. Two second pneumatic rods 10 are fixedly connected to the rear side of the fixed block 11. The telescopic ends of the two second pneumatic rods 10 are fixedly connected to the corresponding second sliders 12. Each fixed frame 23 is fixedly connected to the upper end of the corresponding mold plate 14. The L-shaped block 16 is fixed to the front side of the L-shaped fixed steel 13. The second slider 12 is driven to slide along the second slide rail by the telescopic movement of the second pneumatic rods 10, thereby driving the L-shaped fixed steel 13 and the mold plate 14 to reciprocate in the front and back directions.

[0035] The frame 1 has a placement platform 3 on its right side, which is used to place the collection frame for convenient collection of the finished bearings. The right side of the conveying channel 4 is connected to a discharge plate 15. The lower end of the discharge plate 15 is equipped with a shock-reducing component to reduce the impact force when the bearings fall, protecting them. The shock-reducing component includes a vertical plate 37. A third slide rail 38 is fixedly connected to the right side of the vertical plate 37. A horizontal block 40 is fixedly connected to the lower end of the third slide rail 38. A rotating block 41 is slidably connected to the third slide rail 38, allowing it to slide up and down along the third slide rail 38. The rotating block 41 and the horizontal block 40 are elastically connected by a fourth spring 39, which provides an upward elastic restoring force to the rotating block 41. A rotating rod 45 is rotatably connected through the rotating block 41. A receiving platform 42 is provided on the right side of the rotating block 41. The receiving platform 42 consists of a horizontal plate and an inclined plate. The inclined plate is fixedly connected to the right side of the horizontal plate. The angle between the inclined plate and the horizontal plane is 5°-10°, which facilitates the smooth sliding of the bearing and prevents the bearing from falling directly when it falls onto the receiving platform 42. A groove is provided on the left side of the receiving platform 42. The rotating rod 45 is fixedly connected to the inner walls of the front and rear sides of the groove. The front side of the rotating rod 45 passes through the receiving platform 42 and is fixedly connected to a gear 43. A rack plate 44 that meshes with the gear 43 is fixedly connected to the front side of the vertical plate 37. The rotation angle of the receiving platform 42 can be adjusted through the meshing transmission of the gear 43 and the rack plate 44.

[0036] The lower end of the feeding plate 15 is fixedly connected to two mounting blocks 35. The adjacent sides of the two mounting blocks 35 are rotatably connected to a rotating shaft 36 through a damping bearing. A square block is fixedly connected to the rotating shaft 36. The square block is fixedly connected to the left side of the vertical plate 37, so that the vertical plate 37 can rotate with the rotating shaft 36, which facilitates the placement and retrieval of the collection box.

[0037] The functional principle of this invention can be explained by the following operation: First, in the bearing feeding stage, the vibrating feeding plate 2 arranges the bearings in an orderly manner and conveys them into the U-shaped conveying channel 4. The vibration force is used to ensure that the bearings move stably in the conveying channel 4, preparing for the subsequent conveying process.

[0038] Before each conveying, the number of arc-shaped blocks 22 entering the arc-shaped opening 21 needs to be adjusted according to the size of the bearing in the vibrating feed tray 2. First, the stretching distance of the third pneumatic rod 17 is controlled according to the size of the bearing, which drives the strip plate 19 and multiple abutment blocks 18 to move backward. The abutment blocks 18 press the rectangular blocks 24 from front to back. Since the rear side of each abutment block 18 is arc-shaped, it will cause the rectangular blocks 24 to drive the vertical rod 27 to move downward, thereby allowing the arc-shaped blocks 22 on each assembly component to move downward sequentially from front to back and contact the upper end of the mold plate 14.

[0039] When a suitable number of arc-shaped blocks 22 move down and contact the upper end of the mold plate 14, the second spring 29 is in a compressed state. Then, pressing the control switch causes the electromagnet 34 to be energized, generating a repulsive force on the connecting rod 32 located at the front. The connecting rod 32 at the front moves the corresponding arc-shaped block 22 backward (when the number of moving arc-shaped blocks 22 is greater than or equal to two, since the arc-shaped block 22 is fitted inside the previous arc-shaped block 22, the previous arc-shaped block 22 will push the arc-shaped block 22 behind it to move accordingly). When the arc-shaped block 22 moves to the top of the arc-shaped opening 21 and is no longer obstructed, under the elastic action of the second spring 29, the sliding L-rod 30 moves down, causing the arc-shaped block 22 to enter the arc-shaped opening 21, changing the radius of the remaining space within the arc-shaped opening 21, ensuring that the outer wall of the bearing can fit tightly against the inner wall of the arc-shaped block 22, laying the foundation for subsequent precise conveying.

[0040] It is worth mentioning that when the arc-shaped block 22 moves to the rear, the arc-shaped block 22 located at the rear will first move to the top of the arc-shaped opening 21. At this time, although the arc-shaped block 22 at the rear is no longer blocked, it cannot move down because the sliding L-rod 30 at the rear is located above the sliding L-rod 30 at the front.

[0041] In the conveying process, after the first bearing is conveyed onto the conveying channel 4, the control system controls the second pneumatic rod 10 to extend, pushing the second slider 12 to move backward along the second slide rail. This, in turn, causes the L-shaped fixed steel 13 and multiple mold plates 14 to move backward synchronously, precisely locking the bearing into the leftmost arc-shaped opening 21, while simultaneously ensuring a tight fit between the bearing and the rear inner wall of the conveying channel 4. Subsequently, the first pneumatic rod 7 retracts, driving the first slider 8 to move to the right along the first slide rail 6. This, in turn, causes the two mold plates 14 to move to the right as a whole via the moving disk 9, thereby conveying the bearing locked into the arc-shaped opening 21 to the right. After this section of conveying is completed, the second pneumatic rod 10 is first controlled to retract, causing the second slider 12 to move the mold plate 14 forward to reset, separating the arc-shaped opening 21 from the bearing.

[0042] Next, the first pneumatic rod 7 extends, driving the moving disk 9 to move the two mold plates 14 to the left and reset. This process is repeated to transport newly delivered bearings to the conveying channel 4: the second pneumatic rod 10 extends again, causing the mold plate 14 to move backward. At this time, the second arc-shaped opening 21 from left to right will engage the previous bearing, continuing to transport it to the right as the mold plate 14 moves to the right, and so on, gradually transferring the bearings to the right. Once the bearings have moved to the right side of the conveying channel 4, they will be neatly arranged in that area. With each movement of the mold plate 14 to the right, the arranged bearings will be pushed to move synchronously to the right, eventually causing the bearings to fall onto the unloading plate 15 and slide downwards.

[0043] Finally, in the unloading protection stage, the completed bearing slides down the unloading plate 15 onto the receiving platform 42 of the shock-reducing assembly. The bearing's gravity causes the rotating block 41 to slide down along the third slide rail 38, compressing the fourth spring 39. As the rotating block 41 moves the receiving platform 42 downwards, the meshing of the gear 43 and rack 44 causes the rotating rod 45 to rotate, causing the receiving platform 42 to rotate downwards. When the receiving platform 42 rotates downwards to a certain angle (greater than 60 degrees), the bearing falls into the collection frame under gravity. At this time, under the elastic action of the fourth spring 39, the rotating block 41 will move the receiving platform 42 upwards to reset. Due to the meshing of the gear 43 and rack 44, the receiving platform 42 will rotate in the opposite direction to reset. When it is necessary to place or remove the collection frame, the operator can push the vertical plate 37 to rotate counterclockwise around the rotating shaft 36, causing the shock-reducing assembly to rotate to a horizontal position, improving operational convenience and effectively protecting the bearing from collision damage.

[0044] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
