Description

Technical Field

[0001] This utility model belongs to the field of welding wire spool technology, and in particular relates to a welding wire spool for winding welding wire. Background Technology

[0002] Welding wire spools are used to wind welding wire, facilitating its storage and use. Currently, welding wire spools often adopt an I-beam structure, which occupies a large space during production, transportation, and storage, especially during transportation, where the large space requirement leads to low transportation efficiency. To solve this problem, detachable welding wire spool structures have been developed. For example, Chinese utility model patent application number 2021204502294 discloses a polymer welding wire spool with foldable and rotatable arc-shaped rotating plates connected to two side plates. During assembly, the rotating plates on the two side plates are interlocked and fixed together to form an I-beam structure. However, in this structure, the rotating plate positions are fixed, meaning the winding shaft position is fixed when the rotating plate forms the winding shaft, which cannot meet diverse needs. Furthermore, during assembly, the rotating plate on one side plate is inserted into a through groove on the other side plate and engaged with the groove by a locking block, so the reliability still needs improvement. Utility Model Content

[0003] In view of this, the present invention aims to overcome the shortcomings of the above-mentioned problems in the prior art and proposes a welding wire spool for winding welding wire.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A welding wire spool for winding welding wire includes a first connecting spool and a second connecting spool. Multiple T-shaped connecting grooves are evenly formed on the inner sidewall of the first connecting spool, and the connecting grooves are opened on the circumferential sidewall of the first connecting spool. Multiple radially arranged connecting holes are formed on the second connecting spool corresponding to each connecting groove. A T-shaped connecting rod is horizontally engaged and fixed in each connecting groove, and the end of the connecting rod is engaged in one of the corresponding connecting holes.

[0006] Furthermore, the end of the connecting rod is provided with a snap-fit ​​edge integrally formed with the connecting rod on the side facing the central axis of the second connecting plate. The snap-fit ​​edge snaps into the outer wall of the corresponding connecting hole, and the sum of the thickness of the snap-fit ​​edge and the thickness of the connecting rod is less than or equal to the height of the connecting hole.

[0007] Furthermore, each connecting hole has a mounting groove on the side away from the central axis of the second connecting plate. A wedge-shaped abutment block is connected to the mounting groove by a spring. The inclined surface of the abutment block is set towards the central axis of the second connecting plate. The end of the abutment block can pass through the mounting groove, and the connecting rod abuts against the corresponding abutment block.

[0008] Furthermore, on the outer wall of the second connecting plate, each connecting hole is provided with a first threaded hole on the side away from the central axis of the second connecting plate, and each connecting hole connected to the connecting rod is provided with an L-shaped fixing block. The horizontal section of the fixing block is inserted into the connecting hole connected to the connecting rod and abuts against the side of the connecting rod away from the snap-fit ​​edge. The vertical section of the fixing block is provided with an installation hole. The fixing block is fixed together with the second connecting plate by the cooperation of the first screw, the installation hole, and the first threaded hole.

[0009] Furthermore, a through hole communicating with the connecting groove is provided on the outer wall of the first connecting plate corresponding to each connecting hole, and a second threaded hole is provided on the outer side of the horizontal section of each connecting rod. The horizontal section of the connecting rod is engaged in the connecting groove and fixed together with the first connecting plate through the cooperation of the second screw, the through hole and the second threaded hole.

[0010] Furthermore, a first connecting shaft is fixedly connected to the middle of the outer side of the first connecting plate, and a second connecting shaft is fixedly connected to the middle of the outer side of the second connecting plate, and both the first connecting shaft and the second connecting shaft are provided with keyways.

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] The welding wire spool of this utility model connects the first connecting spool and the second connecting spool together through multiple connecting rods to form a detachable welding wire spool for winding welding wire. This makes the production, transportation and storage of the welding wire spool more convenient, as it can be broken down into smaller parts and occupies less space. When in use, it can be reassembled and fixed. Moreover, the position of the connecting rods is adjustable, which can meet different production needs and make the welding wire be wound into welding wire bundles with different inner diameters.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Example 1

[0026] As shown in the figure, a welding wire spool for winding welding wire includes a first connecting spool 1 and a second connecting spool 2. Multiple T-shaped connecting grooves 101 are evenly formed on the inner sidewall of the first connecting spool 1, and the connecting grooves 101 are open on the circumferential sidewall of the first connecting spool 1. Multiple radially arranged square connecting holes 201 are formed on the second connecting spool 2 corresponding to each connecting groove 101. A T-shaped connecting rod 3 is horizontally engaged and fixed within each connecting groove 101, and the end of the connecting rod 3 is engaged in one of the corresponding connecting holes 201. In this embodiment, the number of connecting rods 3 is 3-5. The first connecting spool 1 and the second connecting spool 2 are connected together by multiple connecting rods 3 to form a detachable welding wire spool for winding welding wire. This makes the production, transportation, and storage of the welding wire spool more convenient, as it can be broken down into smaller parts and occupies less space. When in use, it can be reassembled and fixed.

[0027] The end of the connecting rod 3 has a snap-fit ​​edge 301 integrally formed with the connecting rod 3 on the side facing the central axis of the second connecting disc 2. The snap-fit ​​edge 301 snaps into the outer wall of the corresponding connecting hole 201, and the sum of the thickness of the snap-fit ​​edge 301 and the thickness of the connecting rod 3 is less than or equal to the height of the connecting hole 201, ensuring that the end of the connecting rod 3 can pass smoothly through the connecting hole 201. In this embodiment, the snap-fit ​​edge 301 is provided so that when the welding wire is wound, the welding wire is wound on multiple connecting rods 3, and the snap-fit ​​stability between the snap-fit ​​edge 301 and the second connecting disc 2 is further enhanced under the action of the welding wire.

[0028] Each connecting hole 201 has a mounting groove 202 on the side away from the central axis of the second connecting plate 2. A wedge-shaped abutment block 4 is connected to the mounting groove 202 by a spring. The inclined surface 401 of the abutment block 4 faces the central axis of the second connecting plate 2. The end of the abutment block 4 can pass through the mounting groove 202, and the connecting rod 3 abuts against the corresponding abutment block 4. In this embodiment, one end of the spring is fixed to the bottom of the mounting groove 202, and the other end is fixed to the abutment block 4. The abutment block 4 is set as a wedge-shaped structure. Its inclined surface 401 allows the connecting rod 3 to pass smoothly from the inside of the second connecting plate 2 outward. During this process, the connecting rod 3 pushes up the abutment block 4, and when the connecting rod 3 passes through the corresponding connecting hole 201, the locking edge 301 locks into the outer wall of the corresponding connecting hole 201. Then the abutment block 4 rebounds slightly and abuts the connecting rod 3. The cooperation between the abutment block 4 and the locking edge 301 ensures that the connecting rod 3 is firmly connected to the second connecting plate 2.

[0029] On the outer wall of the first connecting plate 1, a through hole 102 is provided corresponding to each connecting hole 201 and communicates with the connecting groove 101. A second threaded hole is provided on the outer side of the horizontal section of each connecting rod 3. The horizontal section of the connecting rod 3 is engaged in the connecting groove 101 and is fixed together with the first connecting plate 1 by the cooperation of the second screw 5, the through hole 102 and the second threaded hole. This arrangement can enhance the connection stability between the connecting rod 3 and the first connecting plate 1.

[0030] A first connecting shaft 103 is fixedly connected to the middle of the outer side of the first connecting disc 1, and a second connecting shaft 204 is fixedly connected to the middle of the outer side of the second connecting disc 2. Both the first connecting shaft 103 and the second connecting shaft 204 are provided with keyways. When the welding wire disc is mounted on the bracket with the corresponding bearings through the first connecting shaft 103 and the second connecting shaft 204, it is easy to fix it to the coupling through one of the connecting shafts with keyways. The coupling is connected to the motor, so that the rotation of the welding wire disc can be driven by the motor.

[0031] The working process of this embodiment is as follows:

[0032] In use, the connecting rods 3 are snapped into the corresponding connecting grooves 101 one by one. The ends of the connecting rods 3 push up the corresponding clamping blocks 4 and then pass through the corresponding connecting holes 201. Here, the position of the connecting rods 3 can be adjusted according to actual needs. When adjusting, simply move the connecting rods 3 in the connecting grooves 101 to the appropriate position and insert the ends into the connecting holes 201 at the appropriate positions to make the connecting rods 3 horizontal. The ends of the connecting rods 3 are snapped onto the outside of the connecting holes 201 by the snapping edge 301 and are clamped by the clamping blocks 4 to prevent the second connecting plate 2 from detaching from the connecting rods 3 during use. Finally, the connecting rods 3 and the first connecting plate 1 are fixed together by the second screws 5 to fix the connecting rods 3 and the first connecting plate 1, thus achieving a stable installation of the connecting rods 3 between the first connecting plate 1 and the second connecting plate 2.

[0033] Example 2

[0034] As shown in the figure, a welding wire spool for winding welding wire will replace the fixing structure of the connecting rod and the second connecting spool in the previous method with the following structure: On the outer wall of the second connecting spool 2, each connecting hole 201 is provided with a first threaded hole 203 on the side away from the central axis of the second connecting spool 2. Each connecting hole 201 connected to the connecting rod 3 is provided with an L-shaped fixing block 6. The horizontal section of the fixing block 6 is inserted into the connecting hole 201 connected to the connecting rod 3 and abuts against the side of the connecting rod 3 away from the snap-fit ​​edge 301. The vertical section of the fixing block 6 is provided with an installation hole. The fixing block 6 is fixed to the second connecting spool 2 by the cooperation of the first screw 7, the installation hole, and the first threaded hole 203.

[0035] The working process of this embodiment is as follows:

[0036] For fixing the end of the connecting rod 3 and the second connecting plate 2, in addition to using the snap-fit ​​edge 301 to snap into the outside of the connecting hole 201, a fixing block 6 is also used to insert its horizontal section into the gap between the connecting rod 3 and the corresponding connecting hole 201, and the vertical section of the fixing block 6 is fixed to the outer wall of the second connecting plate 2 by the first screw 7, which further enhances the connection stability between the connecting rod 3 and the second connecting plate 2.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
