Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing transportation technology, and in particular to a turnover box for bearing production. Background Technology
[0002] Because of the significant difference in size between the inner and outer rings of a bearing (typically the outer ring diameter is larger than the inner ring diameter), existing technologies often require the use of dedicated turnover boxes of different specifications for each. This situation not only increases the procurement cost of turnover boxes for enterprises, but also causes great inconvenience to warehouse management and production scheduling due to the wide variety of turnover boxes, thus increasing the management difficulty.
[0003] Meanwhile, in actual production, the inner and outer rings of bearings are usually arranged in the same direction in the turnover box. It is difficult to quickly distinguish whether the inner or outer ring is placed in the box from the appearance alone, which can easily lead to mis-taking and misuse during process connection, affecting production efficiency.
[0004] In addition, the fixed structure of traditional turnover boxes makes it impossible to flexibly switch the objects stored according to production needs, which further reduces the flexibility and continuity of production. Utility Model Content
[0005] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes a turnover box that can adapt to the storage needs of the inner and outer rings and facilitate quick differentiation.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A bearing manufacturing turnover box includes a box body with a rectangular placement cavity open at the top. Multiple first slots are sequentially spaced on both length side walls of the rectangular placement cavity. Short partitions are detachably engaged between two opposing first slots. The multiple short partitions divide the rectangular placement cavity into multiple inner ring placement areas for placing bearing inner rings. Two short partitions can be sequentially joined to form a long partition. Multiple second slots are spaced on both width side walls of the rectangular placement cavity. The long partition can be engaged within two opposing second slots, and the multiple long partitions divide the rectangular placement cavity into multiple outer ring placement areas for placing bearing outer rings.
[0008] In some embodiments, a short slot is connected to the bottom wall of the rectangular placement cavity and between two front-to-back opposing first slots, and the lower end of the short partition can be inserted into the short slot.
[0009] In some embodiments, a long slot is connected to the bottom wall of the rectangular placement cavity and between two second slots located opposite each other on the left and right sides, and the lower end of the long partition can be inserted into the long slot.
[0010] In some embodiments, each of the two ends of the short partition is provided with a first insertion post extending upward and downward, and the bottom wall of the first slot and the second slot is provided with a first insertion interface for the first insertion post to be inserted. When the two short partitions are spliced together to form a long partition, the two first insertion posts form a second insertion post, and the bottom wall of the long slot is provided with a second insertion interface for the second insertion post to be inserted.
[0011] In some embodiments, a connecting sleeve is further included, the connecting sleeve having a through hole, into which the second plug can be inserted.
[0012] In some embodiments, an outwardly flared flange is provided at the upper edge of the housing.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This turnover box, with its detachable design and splicing capabilities of short and long partitions, eliminates the need for separate turnover boxes for the inner and outer rings of the bearings. Only one turnover box is required; by adjusting the installation method of the partitions, it can be flexibly switched between inner and outer ring storage modes, significantly reducing the number of turnover boxes needed, lowering procurement costs, and simplifying warehouse management processes and reducing management complexity.
[0015] 2. Because the inner ring placement area is divided by short partitions and the outer ring placement area is divided by long partitions (two short partitions joined together), there is a significant difference in the partitioning of the two placement areas. When the turnover box is in the inner ring storage state, the arrangement of the short partitions is completely different from the arrangement of the long partitions in the outer ring storage state. Workers can quickly determine whether the box contains the inner or outer ring of the bearing by observing the shape of the partitions, effectively avoiding the problem of mis-taking or misuse.
[0016] 3. The partition is easy to install and remove, and staff can quickly switch the mode of the turnover box according to the production plan, reducing the time cost of process conversion. Attached Figure Description

[0021] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.
[0022] like Figures 1-4 A bearing production turnover box is shown, comprising a box body 1, the box body 1 having a rectangular placement cavity 2 with an opening at the top, a plurality of first slots 3 are sequentially spaced on the two length side walls of the rectangular placement cavity 2, and short partitions 4 are detachably engaged between two opposite first slots 3, the plurality of short partitions 4 can divide the rectangular placement cavity 2 into a plurality of inner ring placement areas 5 for placing the inner ring 10 of the bearing, two short partitions 4 can be sequentially spliced to form a long partition 7, a plurality of second slots 6 are spaced on the two width side walls of the rectangular placement cavity 2, the long partition 7 can be engaged in two opposite second slots 6, the plurality of long partitions 7 can divide the rectangular placement cavity 2 into a plurality of outer ring placement areas 8 for placing the outer ring 11 of the bearing.
[0023] Based on the above structure, the function can be switched by selecting to install either the short partition 4 or the long partition 7: when the short partition 4 is installed, the rectangular placement cavity 2 is divided into multiple inner ring placement areas 5 by using the limiting effect of the first slot 3, which is adapted to the size of the bearing inner ring 10; when the two short partitions 4 are spliced together to form the long partition 7 and installed in the second slot 6, the separated outer ring placement area 8 can be adapted to the bearing outer ring 11.
[0024] This allows a single set of storage boxes to accommodate both inner and outer bearing rings, eliminating the need for additional dedicated storage boxes and reducing procurement and management costs. The difference in the shape of the partitions allows for quick differentiation between inner and outer rings, preventing misuse.
[0025] See Figures 1-3 As shown, a short slot 21 is connected between the two first slots 3 located opposite each other on the bottom wall of the rectangular placement cavity 2, and the lower end of the short partition 4 can be inserted into the short slot 21.
[0026] When installing the short partition 4, both ends of the short partition 4 are inserted into the first slot 3, and the lower end is inserted into the short slot 21, thereby installing the short partition 4. The setting of the short slot 21 can enhance the installation stability of the short partition 4, avoid the partition from loosening or tilting due to vibration during turnover, and ensure the safety of the bearing inner ring storage.
[0027] Furthermore, a long slot 31 is connected between the two second slots 6 located on opposite sides of the bottom wall of the rectangular placement cavity 2, and the lower end of the long partition 7 can be inserted into the long slot 31.
[0028] The long partition 7 and the short partition 4 are installed in the same way.
[0029] See Figures 1-4 As shown, both ends of the short partition 4 are provided with first insertion posts 41 extending upwards and downwards. The first insertion posts 41 are integrally injection molded with the short partition 4. The bottom walls of the first slot 3 and the second slot 6 are provided with first insertion interfaces 42 for the first insertion posts 41 to be inserted. When the two short partitions 4 are spliced together to form a long partition 7, the two first insertion posts 41 form a second insertion post 43. The bottom wall of the long slot 31 is provided with a second insertion interface 44 for the second insertion post 43 to be inserted.
[0030] When installing the short partition 4, the first insertion post 41 is inserted into the first insertion interface 42, and triple fixation is achieved with the slot; when splicing the long partition 7, the second insertion post 43 is inserted into the second insertion interface 44 to further enhance the connection strength of the long partition.
[0031] The connection stability between the partition and the box is enhanced by the plug-in structure to prevent the partition from falling off; the plug-in design at the splice ensures the integrity of the long partition 7 and improves the structural reliability of the outer ring placement area 8.
[0032] See Figure 2 , Figure 4 As shown, it also includes a connecting sleeve 51, on which a through hole 52 is provided, and the second insertion post 43 can be inserted into the through hole 52.
[0033] The connecting sleeve 51 is made of hard plastic with a through hole 52 machined in the middle. The hole diameter matches the outer diameter of the second plug-in post 43. When the two short partitions 4 are spliced, the connecting sleeve 51 is put on the outside of the second plug-in post 43, and the through hole 52 fits tightly with the plug-in post. This can enhance the integrity of the short partitions 4 after splicing, prevent the long partitions 7 from separating during use, improve the structural durability of the turnover box, and extend its service life.
[0034] In this utility model, the upper edge of the box body 1 is formed into an outwardly turned flange 61 by injection molding or bending process.
[0035] This makes it easier for staff to move the turnover boxes, improving operational convenience; it also enhances the deformation resistance of the box edges and extends the service life of the box.
[0036] Based on the accompanying drawings and the foregoing display and description of the basic principles, main features, and advantages of this utility model, those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
