Description

Technical Field

[0001] This utility model relates to the field of bearing mounting bracket technology, and more particularly to an adjustable bearing mounting bracket. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. However, when machining bearings in a workshop, there are no corresponding tools for placing the machined bearings.

[0003] Regarding the existing technology patent CN111994144A, which discloses a bearing placement rack, it includes a base plate, a chassis on the upper outer surface of the base plate, a rotating disk on the upper outer surface of the chassis, a mounting frame on the upper outer surface of the rotating disk, a support rod on the upper end of the mounting frame, a placement rod on the side outer surface of the support rod, a push handle on the upper outer surface of the base plate, and a fixing block on the lower outer surface of the base plate. This utility model, by incorporating a rotating disk embedded in the chassis and using an internal rotating shaft, allows the entire placement rack to rotate, facilitating operation and saving time by eliminating the need for movement during placement. The support rod is mounted on the mounting frame via a threaded mounting rod and threaded holes, using a cross-shaped... The mounting bracket ensures excellent balance and stability across its four support rods. Multiple placement rods allow for the storage of a large number of bearings, maximizing capacity. Once full, the bracket is secured by external threads and limit bolts to prevent bearings from slipping and causing accidents. The bracket features casters and a handle for easy movement, facilitating placement and retrieval by workers. Locking plates secure the casters, preventing slippage due to bearing displacement. This bearing rack boasts a simple and rational structure, safe and convenient operation, and facilitates the orderly classification and storage of bearings. It is easy to disassemble and assemble, features a limit function to prevent bearing slippage, a rotating disc for easy worker access, and is easy to move.

[0004] However, the existing bearings are all of different sizes. Placing bearings of different sizes on the bracket is not convenient for subsequent handling. Moreover, simply placing the bearings on the bracket will cause larger diameter bearings to fall off the bracket due to subsequent shaking, resulting in some damage. Utility Model Content

[0005] To overcome the problems of existing bearings having different diameters and being placed on brackets, which are inconvenient for subsequent handling and storage, and also cause larger diameter bearings to fall off during movement, resulting in movement losses.

[0006] The technical solution of this utility model is as follows: an adjustable bearing mounting bracket, including a rotating base, a cross-shaped connecting block, a support rod, a thick rod, a middle rod, and a thin rod. The middle rod is connected through the inside of the thick rod, and the thin rod is connected through the inside of the middle rod. Movable grooves are opened inside the middle rod and the thin rod. Springs are fixedly connected inside the movable grooves. A fixing rod is fixedly connected to one end of the spring. Fixing holes are opened on one side inside the thick rod and the middle rod. Multiple evenly arranged buffer anti-slip pads are fixedly sleeved on the outside of the thick rod, the middle rod, and the thin rod.

[0007] Preferably, when placing different bearings, the middle rod and the thin rod can be extended to classify the bearing placement. At the same time, the extended placement rod can increase the number of bearings that can be placed. In addition, the cushioning anti-slip pads not only block the bearings but also enhance their anti-slip effect, preventing the bearings from falling off and improving the flexibility and practicality of the placement rack.

[0008] Preferably, a cross-shaped connecting block is fixedly connected to the top of the rotating base, and a support frame is fixedly connected to each of the four ends of the upper surface of the cross-shaped connecting block.

[0009] Preferably, support rods are fixedly connected to the upper surfaces of the four support frames, and thick rods are fixedly connected to one side of each of the four support rods.

[0010] Preferably, both the thicker and middle rods have limiting grooves inside.

[0011] Preferably, the four feet on the lower end face of the rotating base are provided with grooves, and universal wheels are movably connected to the left and right sides inside the four grooves.

[0012] Preferably, the fixing rod is inserted into the fixing hole and connected through it, and a through hole is provided on one side of the movable groove, through which the fixing rod and the middle rod pass.

[0013] Preferably, a threaded groove is provided inside one side of the thin rod, and a limit bolt is provided on the other side of the thin rod away from the middle rod, and the limit bolt engages and locks into the threaded groove.

[0014] The beneficial effects of this utility model are:

[0015] This adjustable bearing holder allows the bearings to be disengaged from the fixing holes by pressing the fixing rod. The middle rod is then pulled outward from the inside of the thick rod, and the thin rod is pulled out from the middle rod in the same way. Bearings of different diameters are respectively fitted onto the outside of the thick, middle, and thin rods. The buffer anti-slip pads on the outside of the thick, middle, and thin rods separate each bearing and increase friction, thus achieving an anti-slip effect and ensuring that the bearings will not fall off the outside of the thick, middle, and thin rods, greatly enhancing the practicality of the bearing holder.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Bearings are core components in mechanical equipment that support rotating bodies, reduce friction, and ensure rotational accuracy. Based on their working principle, they can be divided into two main categories: sliding bearings and rolling bearings. Rolling bearings are more widely used. A typical structure includes four parts: an inner ring, an outer ring, rolling elements (balls or rollers), and a cage. Bearing racks are devices used to store and protect bearings, primarily used during storage and transportation to prevent collisions or damage during movement or storage. The main functions of bearing racks include preventing bearings from shaking and generating noise during transportation, and ensuring the stability and safety of bearings during storage and transportation.

[0023] Different types of bearing racks and their characteristics

[0024] Hubei Chuangrui Precision Bearing Co., Ltd.'s bearing rack: This rack uses a carrier plate and pressure plate inside the fixed frame, and springs and buffer pads to reduce the gap between the bearings, preventing shaking and noise during transportation, and also preventing the bearings from being bumped.

[0025] Luoyang Ouna Bearing's small precision parts arrangement and placement device: This device can adjust the unfolded area of ​​the placement plate by rotating the placement plate and counterweight on the bracket. It is suitable for precision parts of different sizes, and the placement position can be changed by rotating the fixed plate structure, which improves the convenience of use.

[0026] Bearing racks from Changzhi Huatai Bearing Manufacturing Co., Ltd.: These racks use support plates and connecting rods within a movable frame, along with rubber rings and positioning grooves, to position and protect bearings, preventing friction and damage between adjacent bearings and extending their service life. While the designs and applications of these racks vary, their common goal is to better protect bearings and reduce the risk of damage during storage and transportation.

[0027] Specifically, the bearing placement rack uses a carrier plate inside a fixed frame. The carrier plate has placement slots, and baffles and springs are installed in the placement slots to neatly arrange and compress the bearings, reducing the gap between the bearings and preventing them from shaking and generating noise during transportation. In addition, drive components and buffer pads can be installed on the placement rack to further reduce the gap between the bearings and prevent them from bumping into each other.

[0028] Key design features of the bearing mounting rack

[0029] Carrier plate and placement slot: A placement slot is provided on the carrier plate for placing bearings; baffle and spring: A baffle and spring are installed in the placement slot. The elasticity of the spring squeezes the bearings together to reduce the gap; drive assembly and buffer pad: The drive assembly drives the pressure plate to move down, and the buffer pad squeezes the bearings to further reduce the gap; U-shaped groove and collection piece: A U-shaped groove is provided on the carrier plate, and a removable collection piece is provided on the placement rack for easy handling of bearings.

[0030] Functions and types of bearing cages

[0031] The main functions of a bearing cage include: separating rolling elements: the cage separates the individual rolling elements, reducing friction and heat generation during operation; maintaining distance: keeping the distance between rolling elements equal, so that the load is evenly distributed; preventing fallout: preventing the rolling elements of separable bearings and bearings in which the inner and outer rings can swing relative to each other from falling out; and guiding rolling elements: guiding the rolling elements in the non-load-bearing area of ​​the bearing.

[0032] Types of bearing cages include: stamped cages: commonly made of steel or copper plates, lighter in weight, allowing lubricating oil to easily enter and remain inside the cage; solid cages: made of metal, phenolic resin fabric, and plastic, suitable for applications requiring high strength and high temperatures.

[0033] Please see Figures 1-5This utility model provides an embodiment of an adjustable bearing holder, including a rotating base 1, a cross-shaped connecting block 2, a support rod 3, a thick rod 5, a middle rod 6, and a thin rod 7. The middle rod 6 is connected through the interior of the thick rod 5, and the thin rod 7 is connected through the interior of the middle rod 6. Both the middle rod 6 and the thin rod 7 have movable grooves 13 inside, and springs 14 are fixedly connected inside each movable groove 13. One end of each spring 14 is fixedly connected to a fixing rod 11. Fixing holes 10 are provided on one side of the interior of both the thick rod 5 and the middle rod 6. Multiple evenly arranged buffer anti-slip pads 9 are fixedly sleeved on the exterior of each of the thick rod 5, the middle rod 6, and the thin rod 7. Figure 1 As shown, the rotating base 1 is included. In this application, the structure of the rotating base 1 is a prior art solution. The applicant will not provide a detailed description of the internal structure and components of the rotating base 1 or their connection relationship. Therefore, the above structure and connection relationship are all prior art. The applicant has not made any improvements to the components inside the rotating base 1.

[0034] Please see Figures 1-2 In this embodiment, a cross-shaped connecting block 2 is fixedly connected above the rotating base 1. Support frames 4 are fixedly connected to the four ends of the upper surface of the cross-shaped connecting block 2. Support rods 3 are fixedly connected to the upper surfaces of the four support frames 4. Thick rods 5 are fixedly connected to one side of the four support rods 3. Limiting grooves are opened inside the thick rods 5 and the middle rods 6. Multiple support rods 3 can be supported by the cross-shaped connecting block 2 and used for the placement of multiple bearings, realizing the telescopic movement of the middle rods 6 and the thick rods 5. At the same time, the telescopic and retractable movement between the thin rods 7 and the middle rods 6 is also possible. When placing different bearings, the middle rods 6 and the thin rods 7 can be stretched out to classify the bearing placement. At the same time, the extended placement rods can also increase the number of bearings that can be placed. By pressing the fixing rod 11, it is disengaged from the fixing hole 10 and pulled out from the inside of the thick rod 5. The thin rods 7 are also pulled out from the middle rod 6 in the same way. At the same time as being pulled out, the fixing rod 11 cup spring 14 pops out to prevent loosening and is fixedly connected through the fixing hole 10.

[0035] Please see Figures 4-5In this embodiment, the four ends of the lower surface of the rotating base 1 are provided with grooves, and the left and right sides of the four grooves are movably connected to casters 12, which facilitates the displacement of the placement rack and makes it more portable and convenient. The fixing rod 11 is inserted into the fixing hole 10 and is connected to it. A through hole 15 is provided on one side of the movable groove 13, and the fixing rod 11 and the middle rod 6 pass through the through hole 15. A threaded groove is provided inside one side of the thin rod 7, and a limit bolt 8 is provided on the other side of the thin rod 7 away from the middle rod 6. The limit bolt 8 engages and is locked into the threaded groove to limit the bearing and prevent it from falling off. Bearings of different diameters are respectively fitted onto the outside of the thick rod 5, the middle rod 6 and the thin rod 7. The buffer anti-slip pads 9 fitted onto the outside of the thick rod 5, the middle rod 6 and the thin rod 7 are used to separate each bearing and increase friction, thereby achieving an anti-slip effect and ensuring that the bearings fitted onto the outside of the thick rod 5, the middle rod 6 and the thin rod 7 will not fall off, greatly enhancing the practicality of the bearing placement rack.

[0036] During operation, the middle rod 6 and the thin rod 7 can be extended to categorize the bearings when placing different bearings. The extended placement rods can also increase the number of bearings that can be placed. By pressing the fixing rod 11, it is disengaged from the fixing hole 10. The middle rod 6 is pulled outward from the inside of the thick rod 5, and the thin rod 7 is pulled out from the middle rod 6 in the same way. At the same time, the fixing rod 11 is anti-loosened by the spring 14 and is fixed through the fixing hole 10. Bearings of different diameters are respectively fitted onto the outside of the thick rod 5, the middle rod 6, and the thin rod 7. The buffer anti-slip pads 9 fitted onto the outside of the thick rod 5, the middle rod 6, and the thin rod 7 separate each bearing and increase friction, thereby achieving an anti-slip effect. This ensures that the bearings fitted onto the outside of the thick rod 5, the middle rod 6, and the thin rod 7 will not fall off, greatly enhancing the practicality of the bearing placement rack.

[0037] Through the above steps, by pressing the fixing rod 11 to disengage it from the fixing hole 10, the middle rod 6 is pulled out from the inside of the thick rod 5, and the thin rod 7 is pulled out from the middle rod 6 in the same way. Bearings of different diameters are respectively fitted onto the outside of the thick rod 5, the middle rod 6, and the thin rod 7. This solves the problem that the existing bearings are all of different diameters and are all fitted onto the bracket, which is inconvenient for subsequent handling and storage. At the same time, the shaking during the movement will cause the larger diameter bearings to fall off, resulting in movement losses.
