Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective box technology, specifically to a driven ball bearing protective box with a buffer structure. Background Technology
[0002] Driven ball bearings are a special type of bearing, mainly composed of a machined thick-walled outer ring, needle or cylindrical rollers, a cage, guide rails or full roll elements, an inner ring or bolts, and a seal. These bearings can withstand high radial loads and certain impact loads, and are characterized by their compact structure, high rotational accuracy, wide adaptability, and convenient installation. Driven ball bearings are widely used in machine tools, metallurgical machinery, textile machinery, printing machinery, and other mechanical equipment and processing lines. During the transportation of small and medium-sized driven ball bearings, the bearings need to be first placed in a protective case, and then the protective case is placed in another transport box for transport. However, existing protective cases suffer from insufficient cushioning performance, poor protection from single-layer trace plates, and the ease with which split protective covers can be lost. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a driven ball bearing protective box with a buffer structure, which has strong buffering and protective performance, improves the safety of the protective box during transportation, and also provides a rotating cover to solve the problem of easy loss of the split cover.
[0004] The technical solution adopted in this utility model is a driven ball bearing protective box with a buffer structure, including a protective box body and a protective cover. A buffer base is provided on the bottom of the protective box body. A lower trace plate is provided inside the protective box body. The lower trace plate is fixed inside the protective box body by the buffer structure. An upper trace plate is provided above the lower trace plate. A limit post is fixed on the upper trace plate and inserted into the lower trace plate. A long shaft is fixed at the middle of one side of the protective box body. One end of the long shaft is fixed to the bottom of the protective box body. The other end of the long shaft passes through the protective cover and connects to a first baffle. A protective cover limiting device is provided on the side wall of the outer side of the protective box body near the long shaft. A small electric actuator is installed inside the protective cover. The telescopic end of the small electric actuator is connected to a lifting block. The lifting block is fixed to the side of the lifting plate. A limit plate is provided on the bottom end of the lifting plate. A pressure sensor is installed in one side of the bottom end of the lifting plate. First insertion holes are provided on both sides of the protective cover.
[0005] The protective cover limiting device includes a pad fixed to the outer wall of the protective box. One end of a short shaft is fixed to both sides of the pad. The other end of the short shaft passes through one side of the rotating rod and connects to a second baffle. An insert rod passes through the other side of the rotating rod. One end of the insert rod passes through a return spring and connects to a lifting plate. The other end of the insert rod passes into a second insertion hole located inside the side of the hanging plate. The hanging plate is fixed to the bottom of the pad. The two ends of the return spring are respectively fixed to the lifting plate and the rotating rod.
[0006] The buffer structure includes a shock absorber and a support column fixed inside the protective box. The top of the shock absorber is fixed to the bottom of the lower trace plate, and a rubber pad is fixed between the support column and the lower trace plate.
[0007] The cushioning base consists of an inner layer of silicone memory foam, a middle layer of honeycomb aluminum cushioning layer, and an outer layer of ABS impact-resistant layer.
[0008] The protective cover is provided with a switch controller, mounting slots, lifting holes and a third through hole. There are a total of 4 mounting slots, and each mounting slot is equipped with a small electric actuator. The 4 small electric actuators are electrically connected to the switch controller. The switch controller is also electrically connected to a pressure sensor. A limit plate passes through the lifting hole, and a long shaft passes through the third through hole.
[0009] The lower and upper trace plates are provided with the same bearing placement grooves. The lower trace plate is also provided with limiting holes around its perimeter, into which limiting pins can be inserted.
[0010] The protective box body is fixed with handles on both sides, and the protective box body and the protective cover are fixed together by a flat lock.
[0011] The rotating rod is provided with a first through hole and a second through hole. A short shaft passes through the first through hole, and an insert rod passes through the second through hole.
[0012] The beneficial effects of this utility model are as follows: In this utility model, a buffer base is provided at the bottom of the protective box body, which can reduce the vibration of the protective box body and the lower trace plate inside the protective box body; a buffer structure is provided at the bottom of the inside of the protective box body, which can further reduce the vibration of the lower trace plate; through the dual design of the buffer base and the buffer structure, the problem of insufficient buffering performance of existing protective boxes is solved.
[0013] This invention comprises two layers of trace plates: a lower trace plate and an upper trace plate. Both the lower and upper trace plates are provided with bearing placement grooves. After the lower part of the driven ball bearing is placed in the bearing placement groove in the lower trace plate, the upper trace plate can be placed on top of the lower trace plate, thus protecting the upper part of the driven ball bearing. This solves the problem of poor protection effect of single-layer trace plates in existing protective boxes. At the same time, it can completely isolate the driven ball bearing from the outside air and also solves the problem of the driven ball bearing being prone to rust during transportation.
[0014] In this invention, a limiting hole is provided on the lower trace plate and a limiting post is provided on the upper trace plate. When the upper trace plate is placed on the lower trace plate, the limiting post can be aligned with the limiting hole to achieve quick alignment, which improves the accuracy and speed of the upper trace plate being placed on the lower trace plate.
[0015] In this utility model, a mounting groove is provided on the protective cover, and a small electric actuator is installed in the mounting groove. The small electric actuator can control the lifting block, lifting plate and limiting plate to rise and fall. When the limiting plate is lowered, the upper trace plate can be tightly attached to the lower trace plate, avoiding the possibility that the upper trace plate will be displaced upward due to vibration during transportation.
[0016] In this utility model, a first baffle, a long shaft, and a cover limiting device are provided. The long shaft passes through the middle of the protective cover, allowing the protective cover to rotate around the long shaft. At the same time, the first baffle prevents the protective cover from detaching from the top of the long shaft, solving the problem of easy loss of the split protective cover. Meanwhile, first insertion holes are provided on both sides of the protective cover. When the protective cover is opened and rotated onto the pad, the insertion rod in the cover limiting device can be inserted into the first insertion hole, which can stabilize the position of the protective cover and prevent it from rotating. This avoids the possibility of the protective cover rotating and causing damage to the driven ball bearing when handling it. Attached Figure Description

The lifting block 13 is fixed on the side of the lifting plate 15. A limiting plate 16 is provided on the bottom end of the lifting plate 15. A pressure sensor 14 is installed in one side of the bottom end of the lifting plate 15. First insertion holes 20 are provided on both sides of the protective cover 17.
[0025] The protective cover limiting device includes a pad 22 fixed on the outer wall of the protective box body 2. One end of a short shaft 26 is fixed on both sides of the pad 22. The other end of the short shaft 26 passes through one side of the rotating rod 23 and connects to the second baffle 21. An insert rod 27 passes through the other side of the rotating rod 23. One end of the insert rod 27 passes through a return spring 28 and connects to the lifting plate 24. The other end of the insert rod 27 passes into the second insertion hole 30. The second insertion hole 30 is located inside the side of the hanging plate 31. The hanging plate 31 is fixed on the bottom end of the pad 22. The two ends of the return spring 28 are respectively fixed on the lifting plate 24 and the rotating rod 23.
[0026] The buffer structure includes a shock absorber 5 and a support column 3 fixed inside the protective box body 2. The top of the shock absorber 5 is fixed to the bottom of the lower trace plate 6, and a rubber pad 4 is fixed between the support column 3 and the lower trace plate 6.
[0027] The buffer base 1 is composed of an inner silicone memory foam 37, a middle honeycomb aluminum buffer layer 38, and an outer ABS impact-resistant layer 39.
[0028] The protective cover 17 is provided with a switch controller 11, a mounting slot 34, a lifting hole 35, and a third through hole 36. There are a total of 4 mounting slots 34, and each mounting slot 34 is equipped with a small electric actuator 12. The 4 small electric actuators 12 are electrically connected to the switch controller 11. The switch controller 11 is also electrically connected to a pressure sensor 14. A limit plate 16 passes through the lifting hole 35, and a long shaft 19 passes through the third through hole 36.
[0029] The lower trace plate 6 and the upper trace plate 9 are provided with the same bearing placement groove 33. The lower trace plate 6 is also provided with limiting holes 32 around its perimeter, and a limiting post 8 can be inserted into the limiting hole 32.
[0030] The protective box body 2 is fixed with handles 7 on both sides, and the protective box body 2 and the protective cover 17 are fixed together by a flat lock 10.
[0031] The rotating rod 23 is provided with a first through hole 25 and a second through hole 29. A short shaft 26 passes through the first through hole 25, and an insert rod 27 passes through the second through hole 29.
[0032] When using this driven ball bearing protective box with a buffer structure, place the lower part of the driven ball bearing into the bearing placement groove 33 on the lower guide plate 6, then lift the upper guide plate 9, align the limiting post 8 with the limiting hole 32 and insert the limiting post 8 into the limiting hole 32, so that the upper guide plate 9 and the lower guide plate 6 are in contact. Then pull the lifting plate 24 outward to make the insertion rod 27 leave the first insertion hole 20, then rotate the rotating rod 23 downward to rotate the insertion rod 27 to the lower position, then insert the insertion rod 27 into the second insertion hole 30, stabilize the position of the rotating rod 23, and then rotate the protective box. The cover 17 covers the protective box body 2 and locks it on top of the protective box body 2 with the flat lock 10. Then, the small electric push rod 12 is activated by the switch controller 11. The small electric push rod 12 retracts, causing the lifting block 13 to move downward. The downward movement of the lifting block 13 drives the lifting plate 15 to move, causing the limit plate 16 to move downward. When the limit plate 16 is close to the upper trace plate 9, the pressure sensor 14 will sense the pressure and transmit the signal to the switch controller 11, causing the small electric push rod 12 to stop automatically. The placement of the driven ball bearing is then completed.
[0033] During transportation, the buffer base 1 can reduce the vibration of the entire protective box body 2, and the rubber pad 4 and shock absorber 5 can reduce the vibration of the lower trace plate 6 and the upper trace plate 9, thereby reducing the vibration of the driven ball bearings in the lower trace plate 6 and the upper trace plate 9.
[0034] In this utility model, a buffer base 1 is provided at the bottom of the protective box body 2. The buffer base 1 can reduce the vibration of the protective box body 2 and the lower trace plate 6 inside the protective box body 2. A buffer structure is provided at the bottom inside the protective box body 2. The buffer structure can further reduce the vibration of the lower trace plate 6. Through the dual design of the buffer base and the buffer structure, the problem of insufficient buffer performance of the existing protective box is solved.
[0035] In this invention, two layers of trace plates are provided: a lower trace plate 6 and an upper trace plate 9. Both the lower trace plate 6 and the upper trace plate 9 are provided with bearing placement grooves 33. After the lower part of the driven ball bearing is placed in the bearing placement groove 33 in the lower trace plate 6, the upper trace plate 9 can be placed on top of the lower trace plate 6, thus protecting the upper part of the driven ball bearing. This solves the problem of poor protection effect of single-layer trace plates in existing protective boxes. At the same time, it can completely isolate the driven ball bearing from the outside air and also solves the problem of the driven ball bearing being prone to rust during transportation.
[0036] In this invention, a limiting hole 32 is provided on the lower trace plate 6, and a limiting post 8 is provided on the upper trace plate 9. When the upper trace plate 9 is placed on the lower trace plate 6, the limiting post 8 can be aligned with the limiting hole 32 to achieve quick alignment, thereby improving the accuracy and speed of the upper trace plate 9 being placed on the lower trace plate 6.
[0037] In this utility model, a mounting groove 34 is provided on the protective cover 17, and a small electric push rod 12 is installed in the mounting groove 34. The small electric push rod 12 can control the lifting block 13, the lifting plate 15 and the limiting plate 16. When the limiting plate 16 is lowered, the upper trace plate 9 can be tightly attached to the lower trace plate 6, avoiding the possibility that the upper trace plate 9 will be displaced upward due to vibration during transportation.
[0038] In this utility model, a first baffle 18, a long shaft 19, and a cover limiting device are provided. The long shaft 19 passes through the middle of the protective cover 17, allowing the protective cover 17 to rotate around the long shaft 19. At the same time, the first baffle 18 can prevent the protective cover 17 from detaching from the top of the long shaft 19, solving the problem of easy loss of the split protective cover. Meanwhile, first insertion holes 20 are provided on both sides of the protective cover 17. When the protective cover 17 is opened and rotated onto the pad 22, the insertion rod 27 in the cover limiting device can be inserted into the first insertion hole 20, which can stabilize the position of the protective cover 17 and prevent the protective cover 17 from rotating again. This can prevent the protective cover 17 from being bumped or damaged when the driven ball bearing is handled.
