Description

Technical Field

[0001] This utility model relates to the technical field of welding wire spool accessories, and in particular to a hot melt welding wire spool clamping device. Background Technology

[0002] Welding wire is a core consumable in the welding process. It is fed continuously to achieve melting and filling, and its performance directly affects the quality of the weld. According to the material and process requirements, welding wire can be divided into solid welding wire, flux-cored welding wire, and metal powder-cored welding wire, with a diameter range of 0.8mm-3.2mm. To meet the demands of automated welding, welding wire needs to be wound onto a dedicated wire spool (also known as a wire feed spool) to form a standardized packaging unit. The structural design of the wire spool must take into account the following key requirements: Rigid support: The wire spool is usually made of high-strength plastic (such as PA66+GF30) or metal (such as galvanized steel plate), with a core diameter of 200mm-500mm and edge guards to prevent the welding wire from slipping off; Dynamic balance: When rotating at high speed (wire feeding speed can reach 15m / min), the wire spool must maintain dynamic balance to avoid swaying due to centrifugal force; Although traditional clamping devices can be used in conjunction with the wire spool, existing wire spool clamping devices have the following main problems: Traditional clamping devices mostly use single-point positioning or elastic buckle structures. When the wire feed is high-speed or the wire spool margin decreases, the spool body is prone to axial movement due to vibration. The replacement efficiency is low, and it mostly relies on manually tightening the nut or tapping to lock it. Each replacement takes a long time and reduces production efficiency. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model proposes a hot melt welding wire spool clamping device.

[0004] The technical solution of this utility model is implemented as follows: A hot melt welding wire spool clamping device includes a support member, a clamping member is installed on the top of the support member, the clamping member includes a top plate and at least one clamping part, and a support rod is fixedly connected to the side of the top plate facing the clamping part. A slot is opened parallel to the length direction of the support rod on the top of the support member. The clamping part includes a clamping plate, a clamping head is fixedly connected to the bottom of the clamping plate, the clamping head matches the slot, and a through hole is opened on the clamping plate, the through hole matches the support rod.

[0005] Preferably, the top of the support rod is open along its length to form a guide groove, and the top of the clamping plate is open to form a top groove. The top groove communicates with the through hole, and a connecting plate is provided inside the top groove. Two springs are fixedly connected between the bottom of the connecting plate and the bottom of the top groove. A limiting rod is also fixedly connected to the bottom of the connecting plate. The free end of the limiting rod is located between the top groove and the through hole, and the limiting rod matches the guide groove. An anti-slip pad is adhered to the bottom of the limiting rod. This design forms a mechanical interlocking mechanism. When the limiting rod is embedded in the guide groove, it can generate a holding force of not less than 200N.

[0006] Preferably, a pull ring is fixedly connected to the top of the connecting plate, and a pull is formed on the pull ring. The pull ring is made of stainless steel, which meets ergonomic requirements and is easy to operate while wearing gloves.

[0007] Preferably, a guide is mounted on the top of the support member, and a guide cavity for guiding the movement of the welding wire is formed on the guide member.

[0008] The guide includes a support frame, two support frames are symmetrically fixedly connected to the top of the support, and two guide rollers are rotatably connected between the two support frames. The surface of the guide rollers is hard anodized, and the friction coefficient is controlled between 0.1 and 0.15 to ensure that the welding wire passes through smoothly.

[0009] Preferably, the support includes a base, the bottom of which is fixedly connected to a foot for supporting itself, and the slot is formed on the top of the base. The base is made of QT500-7 ductile iron to ensure the stability of the device in a vibration environment.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. In use, this utility model achieves modularity and improved stability of wire spool clamping through the coordinated design of the slot, clamping plate, clamping head, support rod, and through hole. Specifically, the support rod passes through the through hole and forms a rigid positioning with the slot. The number of clamping plates can be flexibly adjusted through the interlocking structure of the clamping head and the slot. Together with the top plate, it forms a bidirectional clamping of the wire spool. This structure effectively suppresses centrifugal force sway and axial vibration when the wire spool rotates at high speed, ensuring smooth operation of the spool. When changing operations, only the external clamping plate needs to be pulled to release the clamping. The operation time is shortened compared with traditional devices, improving the mold changing efficiency of the production line.

[0012] 2. When performing the replacement operation, this utility model only needs to pull the external clamp to release the lock, shortening the single operation time and improving the operation efficiency compared with the traditional device. It is more suitable for production environments that require frequent replacement of welding wire spools, such as special welding operations with multiple varieties and small batches.

[0013] 3. In use, this utility model uses a two-stage locking system consisting of a limiting rod, a connecting plate, a spring, and a top groove. After the clamping plate and the support rod are initially positioned, the spring drives the connecting plate to move the limiting rod along the guide groove, achieving precise engagement with the support rod and improving stability during use. At the same time, it allows for unlocking with one hand, balancing structural stability and ease of maintenance.

[0014] 4. During use, this utility model can be adapted to various standard welding wire reels of different diameters by adjusting the number and position of the clamping plates, thus meeting the guiding requirements of welding wires of different diameters. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1As shown, a hot melt welding wire spool clamping device includes a support member 1, a clamping member 3 is installed on the top of the support member 1, the clamping member 3 includes a top plate 31 and at least one clamping part 33, and a support rod 32 is fixedly connected to the side of the top plate 31 facing the clamping part 33. A slot 12 is opened parallel to the length direction of the support rod 32 on the top of the support member 1. The clamping part 33 includes a clamping plate 331, a clamping head 332 is fixedly connected to the bottom of the clamping plate 331, the clamping head 332 matches the slot 12, and a through hole 333 is opened on the clamping plate 331, which matches the support rod 32.

[0025] With the above technical solution, when installing the welding wire spool, the support member 1 is placed at the required position, the welding wire spool to be clamped is then sleeved on the support rod 32, and the welding wire spool is pushed so that it contacts the top plate 31. Then, the clamping plate 331 is sleeved on the support rod 32 through the through hole 333, and the clamping head 332 at the bottom of the clamping plate 331 is engaged with the slot 12 on the support member 1, so that the clamping plate 331 is installed above the support member 1. The clamping plate 331 is pulled along the slot 12 and the support rod 32 until one side of the clamping plate 331 touches the other side of the welding wire spool, thus completing the clamping of the welding wire spool. When more welding wire spools need to be installed, more welding wire spools can be installed according to the above steps. After the welding wire spools are installed, the welding wire spools can be dragged to unwind the welding wire, making the welding wire easy to use.

[0026] After the clamping plate 331 is connected to the support rod 32, in order to prevent the clamping plate 331 from accidentally becoming loose, such as Figure 1 , Figures 4-6 As shown, the top of the support rod 32 is open along its own length to form a guide groove 34, and the top of the clamping plate 331 is open to form a top groove 334. The top groove 334 is connected to the through hole 333, and a connecting plate 337 is provided inside the top groove 334. Two springs 339 are fixedly connected between the bottom of the connecting plate 337 and the bottom of the top groove 334. A limiting rod 335 is also fixedly connected to the bottom of the connecting plate 337. The free end of the limiting rod 335 is located between the top groove 334 and the through hole 333, and the limiting rod 335 matches the guide groove 34. An anti-slip pad 336 is adhered to the bottom of the limiting rod 335.

[0027] In this embodiment, the clamping plate 331 is sleeved on the support rod 32 through the through hole 333, and the locking head 332 at the bottom of the clamping plate 331 is engaged with the locking groove 12 on the support member 1. Before the clamping plate 331 moves, the connecting plate 337 in the top groove 334 is pulled, causing the connecting plate 337 to drive the limiting rod 335 to move. When the connecting plate 337 moves, it will stretch the spring 339, causing the limiting rod 335 to move into the top groove 334. After the limiting rod 335 moves into the top groove 334, the clamping plate 331 is pulled. The clamping plate 331 moves along the support rod 32 and the slot 12 until it touches the welding wire spool. After the clamping plate 331 stops moving, the connecting plate 337 is released, and the spring 339 rebounds, causing the connecting plate 337 to move. The connecting plate 337 then moves the limiting rod 335, causing the limiting rod 335 to move into the through hole 333 until it is inserted into the guide groove 34 at the top of the support rod 32. This fixes the position of the clamping plate 331, making it more stable after the position of the clamping plate 331 is adjusted.

[0028] To facilitate pulling the connecting plate 337, such as Figure 6 As shown, a pull ring 338 is fixedly connected to the top of the connecting plate 337. A pull hole is formed on the pull ring 338. When a person needs to pull the connecting plate 337, the connecting plate 337 is pulled by the cooperation of the pull ring 338 and the pull hole, making the connecting plate 337 easy to pull and improving the convenience of the movement of the limit rod 335.

[0029] When users use welding wire, in order to make the wire move more smoothly, such as Figure 1 and Figure 3 As shown, a guide 2 is installed on the top of the support 1, and a guide cavity for guiding the movement of the welding wire is formed on the guide 2.

[0030] In this embodiment, after the welding wire spool is installed on the support rod 32, the welding wire is guided by the guide 2, making the movement of the welding wire smoother and improving the smoothness of the welding wire pulling.

[0031] Specifically, in one embodiment, regarding the aforementioned guide 2, as... Figure 1 and Figure 3 As shown, the guide 2 includes a support frame 21, two support frames 21 are symmetrically fixedly connected to the top of the support 1, and two guide rollers 22 are rotatably connected between the two support frames 21.

[0032] In this embodiment, the support member 1 supports the support frame 21, and the support frame 21 supports the guide roller 22. The welding wire on the welding wire spool is pulled so that the welding wire passes through the two guide rollers 22. The guide rollers 22 guide the welding wire so that the welding wire is easy to pull.

[0033] Furthermore, in this utility model, regarding the aforementioned support member 1, as follows: Figures 1-2As shown, the support member 1 includes a base 11, with a foot 13 fixedly connected to the bottom of the base 11 for supporting itself, and a slot 12 formed on the top of the base 11.

[0034] In this embodiment, the base 11 is supported by the foot 13, and the base 11 supports the support frame 21 and the top plate 31, making the device more stable during use.

[0035] 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.
