Description

Technical Field

[0001] The present invention relates to the technical field of bearing production, and in particular to a bearing production conveying device. Background Art

[0002] In modern industrial production, bearings, as core components of mechanical transmission systems, have a direct impact on the performance and manufacturing costs of various mechanical products due to their production quality and efficiency. With the continuous improvement of automation in the manufacturing industry, the conveying and assembly stages of the bearing production process have become key bottlenecks in production efficiency. Traditional bearing production and conveying methods often rely on manual assistance or semi-automated equipment. These methods suffer from low conveying efficiency, insufficient positioning accuracy, and high labor intensity, making them difficult to meet the demands of large-scale, high-precision production.

[0003] At present, bearing production conveying devices generally face the following technical pain points: First, bearing workpieces are prone to posture deviation or jamming during the conveying process, especially small bearing components. Due to their small size and precise structure, traditional conveying channels are difficult to achieve stable and orderly feeding, resulting in additional correction time for subsequent assembly processes, seriously affecting the production rhythm; second, the existing conveying devices are not flexible enough to adapt to the rapid switching production of different types of bearings. When changing molds or adjusting positioning parameters, the equipment needs to be shut down, and the equipment utilization rate is low; third, the bearing workpiece lacks an effective buffer protection mechanism in the unloading link at the conveying end point. The workpiece falling at high speed is prone to surface scratches or structural damage due to collision, reducing the product qualification rate.

DETAILED DESCRIPTION

[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 and conveying device includes a frame 1. The frame 1 serves as the basic supporting structure of the entire device and provides a stable installation platform for each component. A vibrating loading tray 2 and a workbench 20 are installed on the upper end of the frame 1. The vibrating loading tray 2 is used to realize automatic loading and orderly arrangement of bearings. The upper end of the workbench 20 is fixedly connected with a conveying channel 4. The conveying channel 4 is U-shaped, and an opening is provided on the front side of the conveying channel 4. This opening design facilitates the subsequent conveying assembly to grab and convey the bearings. The conveying channel 4 is connected to the discharge port of the vibrating loading tray 2 to ensure that the bearings discharged from the vibrating loading tray 2 can smoothly enter the conveying channel 4. A conveying assembly is provided on the upper end of the workbench 20.

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

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

[0031] Two third pneumatic rods 17 are fixedly connected to the rear side of the L-shaped block 16, and the telescopic ends of the two third pneumatic rods 17 are commonly fixedly connected to a strip plate 19. The rear side of the strip plate 19 is fixedly connected to a plurality of blocks 18. The rear side of the blocks 18 is an arc surface. The extension and contraction of the third pneumatic rods 17 drives the strip plate 19 and the blocks 18 to move forward and backward, thereby pushing the rectangular block 24 to realize the downward movement of the vertical rod 27.

[0032] Among them, each connecting rod 32 is elastically connected to the inner wall of the corresponding movable groove 31 through a third spring 33, and an electromagnet 34 is embedded in the front inner wall of the movable groove 31 located on the front side. The rectangular block 24 located on the front side and the adjacent sides of the fixed frame 23 are fixedly connected with mutually cooperating contact blocks 25. A control switch and a power supply are provided on the frame body 1. The control switch, power supply, two contact blocks 25 and the electromagnet 34 form a circuit through wires. When the two contact blocks 25 come into contact, the multiple blocks 18 move to the specified position, and the control switch is pressed. The circuit is turned on, and the electromagnet 34 is energized to generate magnetic force, which produces a repulsive force on the connecting rod 32 on the front side, so that the connecting rod 32 drives the corresponding arc block 22 to move backward.

[0033] Among them, the conveying assembly includes a U-shaped frame 5 arranged at the upper end of the workbench 20, and the upper end of the U-shaped frame 5 is fixedly connected to two first slide rails 6, and the two first slide rails 6 are slidably connected to the first slider 8, and the upper ends of the two first sliders 8 are commonly fixedly connected to a moving plate 9, and the first slider 8 is driven to slide along the first slide rail 6 by the telescopic action of the first pneumatic rod 7, thereby driving the moving plate 9 to achieve reciprocating movement in the left and right directions. Two first pneumatic rods 7 are fixedly connected to the right side of the U-shaped frame 5, and the telescopic ends of the two first pneumatic rods 7 are fixedly connected to the corresponding first slider 8, and two second slide rails are fixedly connected to the moving plate 9, and the two second slide rails are slidably connected to the second slider 12, and the rear sides of the two second sliders 12 are commonly fixedly connected to an L-shaped fixing steel 13, and the upper ends of the L-shaped fixing steel 13 are fixedly connected to two mold plates 14, and the rear sides of the two mold plates 14 are provided with two arc-shaped openings 21, which are adapted to the maximum bearing shape.

[0034] The upper end of the movable disk 9 is fixedly connected to a fixed block 11, and the rear side of the fixed block 11 is fixedly connected to two second pneumatic rods 10. 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 through the telescopic movement of the second pneumatic rod 10, thereby driving the L-shaped fixed steel 13 and the mold plate 14 to realize reciprocating movement in the front and rear directions.

[0035] Among them, a placing table 3 is installed on the right side of the frame 1, and the placing table 3 is used to place the collection frame to facilitate the centralized collection of the processed bearings. The right side of the conveying channel 4 is connected with a blanking plate 15, and the lower end of the blanking plate 15 is provided with a shock-reducing component to reduce the impact force when the bearing falls and protect the bearing. The shock-reducing component includes a vertical plate 37, and the right side of the vertical plate 37 is fixedly connected to a third slide rail 38, and the lower end of the third slide rail 38 is fixedly connected to a horizontal block 40. A rotating block 41 is slidably connected to the third slide rail 38, and the rotating block 41 can slide up and down along the third slide rail 38. The rotating block 41 is elastically connected to the horizontal block 40 through a fourth spring 39. The fourth spring 39 provides an upward elastic reset force for the rotating block 41. A rotating rod 45 is provided on the block 41 for rotation. A receiving platform 42 is provided on the right side of the rotating block 41. The receiving platform 42 is composed 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 is convenient for the bearing to slide smoothly and can prevent the bearing from falling directly when falling toward the receiving platform 42. A groove is provided on the left side of the receiving platform 42, and the rotating rod 45 is fixedly connected to the front and rear inner walls 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. The front side of the vertical plate 37 is fixedly connected to a rack plate 44 meshing with the gear 43. The meshing transmission between the gear 43 and the rack plate 44 can realize the adjustment of the rotation angle of the receiving platform 42.

[0036] Among them, the lower end of the blanking plate 15 is fixedly connected to two mounting blocks 35, and the adjacent sides of the two mounting blocks 35 are connected to a rotating shaft 36 through a damping bearing for common rotation. A square block is fixedly connected to the rotating shaft 36, and 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 is convenient for placing and taking the collection frame.

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

[0038] Before each delivery, the number of curved blocks 22 entering the curved opening 21 is adjusted based on the size of the bearings within the vibrating loading tray 2. First, the extension distance of the third pneumatic rod 17 is controlled according to the size of the bearings, driving the strip plate 19 and multiple stoppers 18 backward. The stoppers 18 squeeze the rectangular blocks 24 from front to back. Because the rear side of each stopper 18 is curved, the rectangular blocks 24 drive the vertical rods 27 downward, causing the curved blocks 22 on each assembly group to move downward from front to back and contact the upper end of the mold plate 14.

[0039] When the appropriate number of arc blocks 22 move downward and contact the upper end of the mold plate 14, the second spring 29 is compressed. The control switch is then pressed. Since the two contact blocks 25 are in contact, the electromagnet 34 is energized to generate a repulsive force on the front connecting rod 32, which in turn drives the corresponding arc block 22 backward (when there are two or more arc blocks 22 moving downward, since the arc block 22 is nested within the previous arc block 22, the front arc block 22 will push the rear arc block 22 to move accordingly). When the arc block 22 moves to the top of the arc opening 21 and is no longer blocked, the second spring 29 elastically acts to slide the L-shaped rod 30 downward, allowing the arc block 22 to enter the arc opening 21, changing the radius of the remaining space within the arc opening 21 and ensuring that the outer wall of the bearing can fit tightly against the inner wall of the arc block 22, laying the foundation for subsequent precise conveying.

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

[0041] During the conveying process, after the first bearing is conveyed to the conveying channel 4, the control system controls the second pneumatic rod 10 to stretch, pushing the second slider 12 to move backward along the second slide rail, thereby driving the L-shaped fixed steel 13 and multiple mold plates 14 to move backward synchronously, accurately clamping the bearing into the arc-shaped opening 21 on the far left, and at the same time making the bearing fit tightly against the rear inner wall of the conveying channel 4. Subsequently, the first pneumatic rod 7 contracts, driving the first slider 8 to move right along the first slide rail 6, and driving the two mold plates 14 to move right as a whole through the movable plate 9, thereby driving the bearing clamped in the arc-shaped opening 21 to be conveyed to the right. After completing this section of conveying, first control the second pneumatic rod 10 to contract, so that the second slider 12 drives the mold plate 14 to move forward and reset, and the arc-shaped opening 21 is separated from the bearing;

[0042] Next, the first pneumatic rod 7 stretches, driving the movable plate 9 to move the two mold plates 14 to the left and reset. The above process is then repeated to transport the newly delivered bearings to the conveying channel 4: the second pneumatic rod 10 stretches again to move the mold plate 14 backward. At this time, the second arc-shaped opening 21 from left to right will clamp the previous bearing, and continue to transport it to the right as the mold plate 14 moves to the right. This process is repeated to achieve the gradual rightward transfer of the bearings. When the bearings move to the right area of ​​the conveying channel 4, they will be neatly arranged in this area. With each rightward movement of the mold plate 14, it will push the arranged bearings to move synchronously to the right, eventually causing the bearings to fall onto the blanking plate 15 and slide down.

[0043] Finally, during the unloading and protection phase, the conveyed bearing slides down the unloading plate 15 onto the receiving platform 42 of the impact-reducing assembly. The bearing's weight causes the rotating block 41 to slide down along the third slide rail 38, compressing the fourth spring 39. As the rotating block 41 drives the receiving platform 42 downward, the gear 43 engages with the rack plate 44, which in turn rotates the rotating rod 45, causing the receiving platform 42 to rotate downward. Once the receiving platform 42 has rotated downward to a certain angle (greater than 60 degrees), gravity forces the bearing to fall into the collection frame. At this point, the elastic force of the fourth spring 39 causes the rotating block 41 to move the receiving platform 42 upward and back to its original position. The engagement of the gear 43 and rack plate 44 causes the receiving platform 42 to rotate in the opposite direction and return to its original position. To place or remove the collection frame, the operator rotates the vertical plate 37 counterclockwise about the rotation axis 36, causing the impact-reducing assembly to return to a horizontal position. This improves ease of operation and effectively protects the bearing from collision damage.

[0044] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
