Description

Technical Field

[0001] This utility model belongs to the field of wire feeding machine technology, and specifically relates to a dual-wire coordinated wire feeding device for a wire feeding machine. Background Technology

[0002] A wire feeder is a device used for automatic wire feeding in welding equipment, especially commonly used in gas metal arc welding (MIG / MAG welding) and tungsten inert gas welding (TIG welding). A dual-wire co-feeding device refers to the use of two independent wire feeding systems in the wire feeder. These two systems can work simultaneously or alternately to achieve specific welding effects.

[0003] Most existing wire feeders operate with two wire feeding mechanisms working together, or each of the two wire feeders has two motors installed. When the two wire feeding mechanisms need to run together, if the two wire feeders are started separately, the wires may break or the finished product may be affected due to the different starting times or the different wire specifications. Therefore, a dual-wire collaborative wire feeding device for wire feeders has emerged. Utility Model Content

[0004] The purpose of this invention is to provide a dual-wire coordinated wire feeding device for a wire feeder, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A dual-wire coordinated wire feeding device for a wire feeder includes two sets of operating mechanisms connected to each other.

[0007] The operating mechanism includes a mounting frame, a motor adapted to be mounted on the outer surface of the mounting frame, a drive gear fixedly mounted on the output end of the motor via a coupling, a placement shaft fixedly connected to the side surface of the drive gear, a clamping assembly disposed at the end of the placement shaft, a transmission shaft meshing with the surface of the drive gear via a transmission gear, a limiting wheel fixedly sleeved on the surface of the transmission shaft, a stop block snapped onto the surface of the limiting wheel, a connecting rod fixedly connected to the inner wall of the stop block, a rotating rod disposed below the connecting rod, and a limiting assembly that engages with the clamping assembly.

[0008] As a preferred embodiment of the present invention, the clamping assembly includes a connecting shaft fixedly connected to the end of the placement shaft, a locking groove formed on both sides of the surface of the connecting shaft, a fixing cylinder fixedly installed on both sides of the surface of the connecting shaft and used in conjunction with the locking groove, and a pressing rod inserted into the center of the fixing cylinder.

[0009] As a preferred embodiment of the present invention, the clamping assembly further includes a compression spring sleeved on the outer surface of the compression rod and a clamping block fixedly connected to the end of the compression spring.

[0010] As a preferred embodiment of this utility model, the limiting component includes a mounting sleeve, a mounting ring fixedly connected to the inner wall of the mounting sleeve, and a limiting frame fixedly installed on the inner wall of the mounting ring.

[0011] As a preferred embodiment of the present invention, the limiting component further includes a reinforcing block, a connecting spring sleeved on one end of the reinforcing block, and a locking plate fixedly connected to the other end of the reinforcing block.

[0012] As a preferred embodiment of this utility model, the limiting component further includes an elastic strip fixedly connected to the card plate, the elastic strip being made of rubber.

[0013] In a preferred embodiment of this utility model, the card plate, the elastic strip, the limiting frame, the connecting spring, and the reinforcing block are all arranged in a circular array.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: by connecting the two sets of operating mechanisms, when synchronous operation is required, turning on one of the motors can also drive the entire mechanism to run. By setting and cooperating with the limiting component and the clamping component, when the two instruments do not need to run at the same time or need to cooperate with each other due to different wire specifications, the two operating mechanisms can be disassembled and separated by the disassembly component and the clamping component. This improves the versatility of the equipment and also improves the operating efficiency of the equipment. Attached Figure Description

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example 1

[0026] Reference Figures 1-5 This is the first embodiment of the present invention, which provides a dual-wire coordinated wire feeding device for a wire feeder, comprising:

[0027] Two sets of operating mechanisms 100 are interconnected;

[0028] The operating mechanism 100 includes a mounting frame 102, a motor 101 adapted to be mounted on the outer surface of the mounting frame 102, a drive gear 104 fixedly mounted on the output end of the motor 101 via a coupling, a placement shaft 103 fixedly connected to the side surface of the drive gear 104, a clamping assembly 105 disposed at the end of the placement shaft 103, a transmission shaft 108 meshing with the surface of the drive gear 104 via a transmission gear, a limiting wheel 109 fixedly sleeved on the surface of the transmission shaft 108, a stop block 110 snapped onto the surface of the limiting wheel 109, a connecting rod 107 fixedly connected to the inner wall of the stop block 110, a rotating rod 111 disposed below the connecting rod 107, and a limiting assembly 106 that engages with the clamping assembly 105.

[0029] Specifically, the clamping assembly 105 includes a connecting shaft 105a fixedly connected to the end of the placement shaft 103, a locking groove 105f formed on both sides of the surface of the connecting shaft 105a, a fixing cylinder 105b fixedly installed on both sides of the surface of the connecting shaft 105a and used in conjunction with the locking groove 105f, and a pressing rod 105c inserted into the center of the fixing cylinder 105b. The clamping assembly 105 also includes a compression spring 105d sleeved on the outer surface of the compression rod 105c and a clamping block 105e fixedly connected to the end of the compression spring 105d.

[0030] In use, after the motor 101 starts, it drives the placement shaft 103 to rotate through the gear 104, which in turn causes the connecting shaft 105a in the clamping assembly 105 to rotate. The compression spring 105d is compressed in the fixed cylinder 105b by the action of the compression rod 105c, pushing the clamping block 105e to move towards the center, thereby achieving the clamping of the item. At the same time, the transmission shaft 108 meshes with the gear 104, driving the limit wheel 109 to rotate. The stop block 110 is engaged with the limit wheel 109. Through the linkage of the connecting rod 107 and the rotating rod 111, the limit assembly 106 and the clamping assembly 105 are precisely matched, limiting the position of the item during the clamping process and ensuring the accuracy and stability of the operation.

[0031] In summary, the two interconnected operating mechanisms 100 achieve highly efficient clamping and positioning functions. The clamping assembly 105, through its precise compression spring 105d and clamping block 105e design, ensures stable clamping of the item, while its symmetrical arrangement guarantees a uniform distribution of clamping force. The cooperation between the limiting assembly 106 and the clamping assembly 105 effectively restricts the movement range of the item, improving operational accuracy. The overall structure is compact, the transmission is reliable, and the operation is simple, greatly enhancing work efficiency and safety.

[0032] Example 2

[0033] Reference Figures 1-5 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a stable function during the use of the device.

[0034] Specifically, the limiting component 106 includes a mounting sleeve 106a, a mounting ring 106c fixedly connected to the inner wall of the mounting sleeve 106a, and a limiting frame 106d fixedly installed on the inner wall of the mounting ring 106c. The limiting component 106 also includes a reinforcing block 106f, a connecting spring 106e sleeved on one end of the reinforcing block 106f, and a locking plate 106g fixedly connected to the other end of the reinforcing block 106f.

[0035] Furthermore, the limiting component 106 also includes an elastic strip 106h fixedly connected to the card plate 106g. The elastic strip 106h is made of rubber. The card plate 106g, elastic strip 106h, limiting frame 106d, connecting spring 106e, and reinforcing block 106f are all arranged in a ring array inside the mounting ring 106c.

[0036] In use, the locking plate 106c in the middle of the limiting component 106 engages with the engaging groove 105f in the clamping component 105 to connect the two mechanisms. When the two structures need to be connected and used together, the locking plate 106c is clamped by the clamping block 105e of the clamping component 105 and then limited to achieve a fixed connection. During operation, the elastic strip 106h in the limiting component 106 will deform to achieve the limiting effect, making the connection between the two structures more secure.

[0037] In summary, the ring array of clamping plates 106g, elastic strips 106h, limiting frames 106d, connecting springs 106e, and reinforcing blocks 106f achieves precise positioning and stable fixation of the clamped items. The rubber elastic strips 106h provide excellent cushioning and adaptability, effectively reducing vibration and noise during operation, while ensuring the safety of the items during clamping. The overall structure enhances the durability and reliability of the system, improves operational efficiency, and reduces maintenance costs.
