Description

Technical Field

[0001] This utility model relates to the field of bearing manufacturing technology, and in particular to a transfer and storage device for ultra-quiet bearings. Background Technology

[0002] Ultra-quiet bearings are mainly used in precision instruments and have higher requirements for stability. Ultra-quiet bearings are actually bearings with very high precision, especially the surface precision of the ball grooves between the inner and outer rings of the bearing, which has extremely stringent requirements.

[0003] The stability and rotational accuracy of a bearing depend on the balls between the inner and outer rings and the grooves containing those balls. Scratches in the grooves between the inner and outer rings affect accuracy. In conventional bearings, a 0.1mm deep scratch on the ball groove surface has little impact on ball rotation when vibration requirements are low. However, ultra-quiet bearings are generally smaller, with very small internal balls (potentially only 1-3mm in diameter). A 0.1mm deep scratch can cause severe vibration in the ball rotation, potentially leading to jerking and noise in the overall bearing operation. Therefore, when manufacturing ultra-quiet bearings, it is necessary to protect both the bearing ring mating surfaces and the balls. High-precision ultra-quiet bearings require scratch-free mating surfaces between the inner and outer rings to ensure the required fit accuracy and achieve ultra-quiet operation.

[0004] Ultra-quiet bearing rings are generally small in size and produced in large quantities. Each packaging involves dozens or even hundreds of ultra-quiet bearings being temporarily stored and transported together, resulting in inconsistencies in storage and transportation. Storing them one by one is extremely cumbersome, making transportation inconvenient. If a bearing ring is dropped or bumped, it will damage the bearing ring. Once the mating surface of this type of ultra-quiet bearing is scratched, it will vibrate abnormally and fail to achieve the purpose of precise mating and quiet operation. It can only be used for applications requiring lower operational precision. Furthermore, it is impossible to determine whether the mating surface of a dropped bearing is scratched, and even small scratches may not be accurately identified. The mating precision of ultra-quiet bearings can only be inspected using a microscope, and the inspection time is even longer than the production time. Therefore, any dropped bearing rings are used for other purposes. Transportation and storage bring more losses to ultra-quiet bearings. This loss is not caused by production and has become a pain point in this industry.

[0005] Based on this, the present invention designs a transfer and storage device for ultra-quiet bearings to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a transfer and storage device for ultra-quiet bearings. Multiple forks can be inserted into multiple bearing rings to string them together for storage and transfer, effectively preventing scattered bearing rings from falling and colliding with the inner and outer rings. This transfer and collection method is far more convenient than handling them one by one. The device can handle a large number of bearing rings at a time, facilitating the transfer of large quantities of bearings through multiple processes such as cleaning, temporary storage, testing, and packaging. It boasts high transfer efficiency. Furthermore, the device's trays can hold a large number of bearing rings, improving storage efficiency and preventing damage to the mating surfaces of the bearing rings and balls. Stacking multiple trays facilitates the organization and storage of bearings.

[0007] This utility model is implemented as follows: a transfer and storage device for ultra-quiet bearings, comprising: support poles, pallets, and fork clamps; The frame pole is a long pole with a handle at one end and multiple forks evenly arranged at the other end. Each fork is a cylindrical straight rod, and the multiple forks are arranged parallel to each other on the same plane. The outer ends of each fork are separated, and the spacing between each fork is the same. The locking fork is a long rod, and the top surface of the locking fork is recessed downward to form multiple locking rod grooves. The locking rod groove is a U-shaped groove with an open top, and the bottom of the locking rod groove is an arc surface. The spacing between each locking rod groove is the same, and each fork position is locked in the locking rod groove one by one. The tray is a square flat plate, and the top of the tray is recessed downward to form multiple material support slots, each of which is vertically arranged in the front-to-back direction; Each of the material trays is a U-shaped tray with an open top, and each of the material trays is arranged parallel to each other on the same plane; Each of the material support troughs is further connected to a support rod trough at both the front and rear ends, and each of the support rod troughs is a U-shaped trough with an open top. Each of the material support grooves coincides with the axis of the support rod grooves at its front and rear ends; Each of the rack slots is provided with a baffle plate on its left and right sides. The baffle plate is a flat plate that is vertically fixed to the top of the pallet. All the baffle plates on the same side of the pallet are on the same vertical plane, and the planes on the front and rear sides of the pallet are parallel to each other. Each of the four corners of the top of the tray has a protruding docking post, and the four corners of the bottom of the tray have overlapping holes. Any two of the trays can be stacked together by the overlapping holes and the docking posts. The tray has an upwardly recessed relief groove, which is a square groove that can be detachably covered by the top plane of another tray.

[0008] Furthermore, the locking fork is an elastic integral long rod made of PVC, the locking rod groove and the fork are interference fit, the curvature of the locking rod groove is greater than that of the semi-circular arc surface, and the spacing between the fork and the spacing between the locking rod groove are the same; Furthermore, the number of the locking slots is the same as the number of the forks; The fork rods can be stably and securely fitted into the corresponding rod slots.

[0009] Furthermore, the material support groove is a semi-circular groove; The top opening width of the support groove is smaller than the top opening width d of the material support groove.

[0010] Furthermore, the depth of the relief groove is greater than the height of the loading bearing, and the depth of the relief groove is greater than the protrusion height of the baffle plate. The top of the baffle plate is higher than the top of the bearing loaded inside the material support trough.

[0011] Furthermore, the handle is provided with anti-slip texture.

[0012] Furthermore, the overlapping hole and the mating post are in clearance fit; The pallet is a single PVC structure with the four edges of the upper and lower pallets tightly fitted together.

[0013] Furthermore, a docking hole is provided at each of the left and right ends of the top of the fork, and the docking hole can be detachably fitted onto the docking post. The fork is positioned and locked in place by the docking hole and the docking post. The mating hole and the mating post are clearance fit.

[0014] The beneficial effects of this utility model are: 1. This utility model integrates multiple forks on the same frame rod and forms them on the same plane, which can string together a large number of ultra-quiet bearing rings for picking and transferring. The transfer efficiency is high. In addition, the addition of a locking fork component can effectively prevent the bearing rings picked up together from falling off, and effectively avoid the possibility of the bearing rings falling off and bumping. 2. A tray for use with the fork is also added, which can be used to store and collect bearing rings. It can also be used with the fork to form a transfer and temporary storage tool. The material tray on the tray can collect all the bearing rings on the fork at once. At the same time, the support slot can lift the fork, so that the fork can be guided into the support slot to remove all the bearing rings on the tray. The efficiency of picking up and removing bearing rings is very high. 3. The process of the fork arm connecting with the pallet to pick up and place the bearing ring is guided by the support rod groove and constrained by the clamping rod groove, ensuring that the fork arm enters the pallet groove in an accurate direction and that picking up and placing is smooth. The pallet is made of PVC material, which will not damage the bearing and effectively prevents the bearing ring from being worn. Multiple pallets can be stacked for storage, which can store a large number of bearings in a smaller space. Moreover, the bearing storage is top and bottom closed, which effectively prevents impurities from getting in. Attached Figure Description

Detailed Implementation

[0018] Please see Figures 1 to 7 As shown, this utility model provides a transfer and storage device for ultra-quiet bearings. To better understand the above technical solution, the following will describe the above technical solution in detail with reference to the accompanying drawings and specific embodiments.

[0019] In a specific embodiment of the technical solution of this utility model: Includes support pole 1, pallet 2, and fork clamp 3; The support pole 1 is a long pole, and a handle 12 is provided at one end of the support pole 1. The handle 12 is provided with anti-slip texture for easy gripping.

[0020] Multiple forks 11 are evenly arranged at the other end of the support rod 1. Each fork 11 is a cylindrical straight rod. The multiple forks 11 are arranged parallel to each other on the same plane. The outer ends of each fork 11 are separated, forming a fork-like structure on the same plane. The spacing between each fork 11 is the same. The multiple forks 11 are fixed together with a support rod 1 to form a fork-like structure, thereby holding the bearing ring with the forks 11 for transportation and handling as a whole.

[0021] The locking fork 3 is a long rod. The top surface of the locking fork 3 is recessed downward and has multiple locking rod grooves 31. The locking rod grooves 31 are U-shaped grooves with open tops and the bottom of the grooves 31 are arc surfaces. The spacing between each locking rod groove 31 is the same, and each fork 11 is locked in the locking rod groove 31 in a one-to-one correspondence. Because it is a set, the locking rod grooves 31 are open. This open structure makes it easy to lock or disassemble with the locking rod grooves 31. The locking fork 3 is a flexible, integral long rod made of PVC. The PVC material allows for smooth sliding between the locking fork 3 and the fork 11. The bottom connection of the locking rod groove 31 is relatively thin, which makes it easy to pry open the locking rod groove 31 to form a certain amount of deformation and to easily remove the fork 11. The locking rod groove 31 and the fork 11 are interference fit. The curvature of the locking rod groove 31 is greater than that of the semi-circular arc surface. That is, the top opening width of the locking rod groove 31 is less than the maximum width inside the locking rod groove 31, and the difference is 1mm. This ensures that the interference between the left and right sides of the locking rod groove 31 and the fork 11 is 0.5mm. The locking fork 3 is also elastic, which allows for easy locking and sliding disengagement. The interval between adjacent locking slots 31 is s, and the interval between adjacent forks 11 is also s. The interval between forks 11 is the same as the interval between locking slots 31. Furthermore, the number of locking slots 31 is the same as the number of forks 11; this allows the forks 11 to be guided in a one-to-one correspondence with the locking slots 31.

[0022] The fork 11 can be stably and securely mounted in the corresponding slot 31.

[0023] The tray 2 is a square flat plate, and the tray 2 is an integral structure made of PVC. The four edges of the upper and lower trays 2 fit tightly together, so as to achieve a tight frame after the trays 2 are stacked, avoiding the chance of foreign objects entering, and making it easy to seal the bearing ring inside the tray 2.

[0024] The top of the tray 2 is recessed downwards and has multiple material trays 21, each of which is vertically arranged in the front-to-back direction; Each material tray 21 is a U-shaped tray with an open top and a semi-circular groove; this makes it easier to place the bearing and remove it. The ring of the material tray 21 should not exceed the semi-circle to avoid jamming the bearing. Each material tray 21 is set parallel to each other on the same plane. The top opening width of the support groove 22 is smaller than the top opening width d of the material support groove 21. The maximum width of the top opening of the material support groove 21 is the diameter d of its semi-circular groove, so that the material support groove 21 and the support groove 22 form a stepped arc. The diameter is the same as the diameter of the bearing it carries. Different bearing models require different diameter d material trays 21 for loading.

[0025] Each material support trough 21 is connected to a support rod trough 22 at both ends, and each support rod trough 22 is a U-shaped trough with an open top. Each material support trough 21 coincides with the axis of the support rod trough 22 at its front and rear ends; Each support slot 22 is provided with a baffle plate 23 on the left and right sides. The baffle plate 23 is a flat plate that is vertically fixed to the top of the pallet 2. All the baffle plates 23 on the same side of the pallet 2 are on the same vertical plane, and the planes on the front and rear sides of the pallet 2 are parallel to each other. The depth of the relief groove 4 is greater than the height of the bearing, and the depth of the relief groove 4 is greater than the protrusion height of the baffle plate 23. As long as the space of the relief groove 4 is sufficient to accommodate the bearing and the baffle plate 23 on the top of the lower pallet 2, mutual interference and collision can be avoided. The top of the baffle plate 32 is higher than the top of the bearing loaded inside the material tray 21, so that the baffle plate 32 can protect the bearing. When the upper tray 2 is stacked downwards, the baffle plate 32 can effectively provide support and a certain degree of protection, preventing the bearing from directly contacting the plane of the upper relief groove 4.

[0026] Each of the four corners of the top of the tray 2 has a protruding docking post 24, and the four corners of the bottom of the tray 2 have overlapping holes 41. Any two trays 2 can be stacked together by the overlapping holes 41 and the docking posts 24. The overlapping hole 41 at the bottom of any one tray 2 can be docked with the docking post 24 at the top of another tray 2. The overlapping hole 41 and the docking post 24 are in clearance fit. The tray 2 has an upwardly recessed relief groove 4, which is a square groove that can be separated and cover the top plane of another tray 2.

[0027] The top left and right ends of the fork 3 each have a docking hole 32, and the docking hole 32 can be detachably fitted onto the docking post 24. The fork 3 is positioned and locked in place by the docking hole 32 and the docking post 24. The mating hole 32 and the mating post 24 are clearance fit, which makes it easy for the clamping fork 3 to be pressed and positioned on either side of the pallet 2. Thus, the clamping rod groove 31 and the support rod groove 22 can cooperate to clamp the fork rod 11, restrict the pushing and pulling of the fork rod 11, and guide it to ensure that the fork rod 11 is directionally stable when it passes through the bearing ring.

[0028] It should be noted that: A bearing has an outer ring and an inner ring, each with a groove for holding the balls. This groove is the most crucial mating surface. Before assembling the bearing, it is necessary to ensure that this mating surface for holding the balls is free of scratches. The inner and outer rings of the bearing themselves do not directly contact each other, but rather the balls are held in place by the concave surfaces of the inner and outer rings. The balls then allow the inner and outer rings to rotate and engage. Of course, there are also other structures such as retaining rings that limit the movement of the balls. The grooved mating surfaces of the inner and outer rings of the bearing are the parts that must maintain absolute precision and flatness during the manufacturing of ultra-quiet bearing rings.

[0029] 1. Existing bearing rings need to be inspected immediately after processing and classified into different sizes. Some bearing rings are unusable due to large errors, while others are classified according to positive and negative tolerances. Bearing rings have inner and outer rings. During installation, bearing rings of different precision levels need to be classified one by one. The classified bearing rings are then transported and stored separately, and the bearing rings also need to be cleaned. If the bearing falls to the ground or other platforms, the ball grooves in the mating surfaces may collide with other objects, causing pits or scratches, resulting in damage to the bearing rings and rendering them unusable. This device can string dozens of bearing rings at once using the fork 11, and both inner and outer rings can be threaded and placed. After the bearing rings are threaded, they will not collide with each other. Only the end faces of the bearing rings will contact each other, which can effectively prevent the ball grooves in the middle of the bearing ring surface from contacting other objects, effectively ensuring the assembly accuracy of the bearings, with high handling efficiency and convenient transportation. 2. Currently, after the bearing rings are manufactured, they are all loaded into a box, resulting in a haphazard stacking of bearings. This easily leads to misalignment between the bearing rings, causing the edges of adjacent bearing rings to abut against the outer ball grooves of another inner bearing ring. Since the bearings themselves have the same hardness and the annular edges are relatively sharp, this can cause the bearing ring grooves to be scratched by other bearing edges. Therefore, haphazardly stacked bearing rings are easily scratched, which seriously affects the bearing mating accuracy. Such bearing rings are unsuitable for high-precision equipment. This device can vertically arrange a large number of bearing rings sequentially and place them one by one in the support groove 21, with the outer wall of the ring surface in contact with the support groove 21. The ball grooves of the bearings are concave inward, effectively preventing the ball grooves from being suspended without contact with any other objects, thus ensuring the accuracy of the bearing ring and ball mating surfaces. Figure 7 As shown, the upper one is the inner ring and the lower one is the outer ring. The ball groove of the inner ring is on the outer wall, and the bearing groove of the outer ring is on the inner ring. The tray 2 of this device can effectively prevent the ball grooves of the inner and outer rings from contacting other objects, and can also prevent the ball grooves from being scratched by other bearing rings, thus effectively ensuring the bearing machining accuracy.

[0030] When using this invention, after the bearing ring is produced, the dimensions of the mating surfaces of the inner and outer rings of the bearing are measured, as well as the dimensions of the non-mating surfaces, especially the dimensions of the ball grooves.

[0031] After measurement, the bearing rings are classified according to their actual dimensions. The classified bearing rings are placed vertically, and the hollow circular holes of the bearing rings are all aligned to form a row. This is the natural conveying state formed by the production equipment.

[0032] This device can directly thread the neatly arranged bearing rings through the fork 11, and also limit the fork 11 through the locking groove 31 of the locking fork part 3 to ensure that the fork 11 remains stable when pushed in.

[0033] String all bearing rings of the same quality onto different forks 11 of the same support rod 1, then hold the handle 12 and clean all the bearing rings on the forks 11. Various cleaning methods such as ultrasonic cleaning and water rinsing can be used. After cleaning, place the bearing rings on the tray 2.

[0034] During operation, align the far end of the fork 11 with the support slot 22 on the back of the pallet 2, and lay the fork 11 flat so that all the bearing rings are placed in the material support slot 21, making the bearing rings stable. The fork 11 can be pulled out directly. The end face of the bearing ring is blocked by the baffle plate 23, and the bearing ring remains in the material support slot 21. The fork 11 is slowly pulled out horizontally from the pallet 2, and all the bearing rings are placed vertically and neatly on the pallet 2. Multiple pallets 2 can be stacked one on top of the other for easy storage of bearing rings. Bearing rings with different tolerances are stored on different pallets 2 for easy use later.

[0035] When the bearing ring inside the pallet 2 is loaded onto the fork 11, the fork clamping piece 3 is first clamped onto the pallet 2 so that the mating hole 32 is aligned with the mating post 24, which makes the support rod groove 22 and the clamping rod groove 31 form a round hole.

[0036] Holding the handle 12, align the multiple forks 11 sequentially with the circular holes formed by the support rod groove 22 and the locking rod groove 31, and then push the support rod 1 to continuously push the forks 11 forward. The circular holes of the support rod groove 22 and the locking rod groove 31 guide the forks 11. At this time, the forks 11 are being pushed towards the end face of the bearing ring. As long as the forks 11 are aligned with the end face of the bearing ring, they can enter the bearing ring. The alignment operation of the end face of the bearing ring ensures that the forks 11 cannot contact the ball groove, thus effectively guaranteeing the accuracy of the mating surface of the ball groove.

[0037] When the fork 11 passes through the support slot 22 at the rear end of the tray 2, all the bearing rings are strung together by the fork 11. Then, the support 1 and the fork 11 can be lifted, making it easier to pick up and put down the bearing rings.

[0038] The front, back, left, and right directions referred to in this device refer to the orientations shown in the accompanying drawings. The far end of the fork 11 refers to the separated, non-contact end. One end of the support rod 1 is the rear end, which is the front end of the tray 2.

They do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation.
