Technical Field

[0001] This utility model relates to the field of bushing technology, specifically to an aluminum coil bearing bushing. Background Technology

[0002] In the aluminum processing industry, the winding of aluminum coils is a crucial step in the production process. Traditional aluminum coil support devices often employ simple cylindrical bushings, relying on friction and the gradual tightening of the aluminum coil as the bushing rotates to secure it. This often results in unstable coil fixation, easy slippage, or detachment, especially when handling aluminum coils of varying thicknesses, where its adaptability is poor, necessitating frequent replacement or adjustment of the support device.

[0003] In view of this, we propose an aluminum coil bearing bushing to solve the existing problems. Utility Model Content

The rectangular grooves extend along the axial direction of the bushing body, and a strip block is detachably installed in the rectangular groove. A locking groove for fixing and clamping the aluminum coil is formed between the side wall of the strip block in the length direction and the side wall of the rectangular groove in the length direction.

[0006] Preferably, the bushing body is further provided with a snap-fit ​​structure for transmission connection with the winding mechanism.

[0007] Preferably, the snap-fit ​​structure is a connecting groove symmetrically arranged at both ends of the bushing body along its length.

[0008] Preferably, the snap-fit ​​structure is a transmission key installed in the inner wall of the through hole of the bushing body, and the transmission key extends along the axial direction of the bushing body.

[0009] Preferably, the transmission key is detachably connected to the inner wall of the through hole of the bushing body.

[0010] Preferably, the two ends of the bushing body are provided with outwardly flared chamfers.

[0011] Preferably, the strip block is provided with a plurality of countersunk holes, and bolts are provided in the plurality of countersunk holes. The bolts pass through the countersunk holes to bolt the strip hole to the bushing body.

[0012] Compared with the prior art, the beneficial effects of this utility model are: this utility model forms a locking groove by setting a detachable strip block on the outer surface of the bushing body to achieve flexible clamping of aluminum coils of different thicknesses. The bushing itself is provided with a snap-fit ​​structure to ensure a stable connection between the bushing and the winding mechanism and to enable efficient power transmission, thereby improving the efficiency of aluminum coil winding operations.

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0018] like Figure 1 As shown, the present invention proposes an aluminum coil bearing bushing, comprising a columnar bushing body 1, a through hole 12 at the center of the axis of the bushing body 1, and a plurality of rectangular grooves 11 that are equally distributed on the outer surface of the bushing body 1 and are radially deepened towards the surface of the bushing body 1. The rectangular grooves 11 extend along the axial direction of the bushing body 1, and strip blocks 2 are detachably installed in the rectangular grooves 11. A locking groove 4 for fixing and clamping the aluminum coil is formed between the side wall of the strip block 2 in the length direction and the side wall of the rectangular groove 11 in the length direction.

[0019] In this embodiment, the bushing body 1 is also provided with a snap-fit ​​structure for transmission connection with the winding mechanism.

[0020] In this embodiment, the snap-fit ​​structure is a connecting groove 14 symmetrically arranged at both ends of the bushing body 1 along its length.

[0021] In this embodiment, the transmission key 3 is detachably connected to the inner wall of the through hole 12 of the bushing body 1.

[0022] In this embodiment, the two ends of the bushing body 1 are provided with outwardly flared chamfers 13, so that the bushing body 1 will not interfere with the winding mechanism when connected, and helps to reduce the collision or friction between the bushing body 1 and other parts of the winding mechanism during the rotation process.

[0023] In this embodiment, the strip block 2 is provided with a plurality of countersunk holes 21, and bolts are provided in the plurality of countersunk holes 21. The bolts pass through the countersunk holes 21 to bolt the strip hole to the bushing body 1, which facilitates the detachable connection between the strip block 2 and the bushing body 1, making it easier to disassemble and install when the strip block 2 needs to be replaced or adjusted to adapt to aluminum coils of different thicknesses.

[0024] The working principle of the aluminum coil support bushing based on Embodiment 1 is as follows: the bushing body 1 serves as the support structure for winding the aluminum coil. The columnar surface of the bushing body 1 supports the aluminum coil. The central through hole 12 of the bushing body 1 is used to connect with the shaft of the winding mechanism, thereby realizing the rotation of the bushing body 1. The rectangular grooves 11 evenly distributed on the outer surface of the bushing body 1 are used to install the strip blocks 2. The sidewalls of the strip blocks 2 and the sidewalls of the rectangular grooves 11 together form a locking groove 4. The locking groove 4 is used to clamp the edge of the aluminum coil, thereby making the edge of the aluminum coil... It is firmly connected to the bushing body 1. The bushing body 1 has connecting grooves 14 at both ends along its length. The connecting grooves 14 are tightly engaged with the transmission components of the winding mechanism to achieve a stable transmission effect. The winding mechanism can transmit power to the bushing body 1, causing the bushing body 1 to rotate under the drive of the winding mechanism. The aluminum coil can rotate and be wound. By installing strip blocks 2 of different widths, the width of the locking groove 4 can be changed, which can flexibly adapt to the winding operation of aluminum coils of different thicknesses. Example

[0025] like Figure 2 and Figure 3 As shown in Embodiment 2, the snap-fit ​​structure is a transmission key 3 installed in the inner wall of the through hole 12 of the bushing body 1. The transmission key 3 extends along the axial direction of the bushing body 1 and engages with the transmission structure of the winding mechanism, thereby enabling the winding mechanism to drive the bushing body 1 to rotate through the transmission structure and the transmission key 3 engaged with the transmission structure to wind the aluminum coil.

[0026] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
