Description

Technical Field

[0001] This utility model relates to the technical field of wire feeding in a welding machine, and in particular to a wire feeding device for a welding machine. Background Technology

[0002] Welding wire is an indispensable filler material in the welding process. It is usually used in conjunction with flux or shielding gas to join metal workpieces.

[0003] In existing wire feeding devices for surfacing welding machines, such as the wire feeding device for a surfacing welding machine disclosed in utility model patent application number 202020641237.9, the welding wire is first wound in the wire guiding mechanism and then fed to the wire pressing mechanism under the guidance of the wire guiding mechanism. At this time, the drive mechanism drives the wire pressing mechanism to pull the welding wire, so that the welding wire can be automatically fed without manual pulling. When the coiled welding wire passes through the wire pressing mechanism, a straightening mechanism is set on the side of the wire pressing mechanism. The straightening mechanism can straighten the coiled welding wire, so that the coiled welding wire can be fully straightened when it is output to the next station. This is beneficial to improving welding efficiency and welding quality.

[0004] However, during the wire feeding process of the welding machine, the roller pushes a large depth, which is not easy to measure accurately and is prone to slippage. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a wire feeding device for a welding machine, which, by setting a wire feeding mechanism and a clamping mechanism, enables precise material feeding through frictional transport of the welding wire during the wire feeding process of the welding machine, and increases friction to prevent material slippage.

[0006] The present invention provides a wire feeding device for a welding machine, including a limiting mechanism; it also includes two sets of wire feeding mechanisms, a clamping mechanism, two sets of synchronization mechanisms and a driving mechanism. The two sets of wire feeding mechanisms are mounted on the limiting mechanism, the clamping mechanism is mounted on the limiting mechanism, the two sets of synchronization mechanisms are mounted on the clamping mechanism and the two sets of wire feeding mechanisms, and the driving mechanism is mounted on the limiting mechanism. The limiting mechanism limits the wire, the wire feeding mechanism feeds the wire, the clamping mechanism clamps the wire, the synchronizing mechanism synchronizes the wire, and the driving mechanism drives the wire. The limiting mechanism limits the welding wire, the clamping mechanism clamps the welding wire, the driving mechanism drives the wire, and the wire feeding mechanism feeds the wire. The synchronizing mechanism works in conjunction with the wire feeding mechanism to achieve synchronized transport of the wire feeding mechanism and the clamping mechanism. This allows for precise material delivery during the wire feeding process of the welding machine through friction transport of the welding wire, and also increases friction to prevent material slippage.

[0007] Preferably, the limiting mechanism includes a base plate and a wire guide tube, with the wire guide tube mounted on the base plate; the wire guide tube limits the welding wire.

[0008] Preferably, the wire feeding mechanism includes a rotating shaft and a spiral bar. The rotating shaft is rotatably mounted on the base plate, and the spiral bar is mounted on the rotating shaft. The rotating shaft drives the spiral bar to rotate and transport the welding wire by friction. The spiral shape of the spiral bar facilitates transportation and movement, while also increasing friction.

[0009] Preferably, the clamping mechanism includes two sets of connecting frames, a second rotating shaft, a second spiral strip, a slider, a screw, and two sets of connecting rods. The two sets of connecting frames are rotatably mounted on the base plate, the second rotating shaft is rotatably mounted on the two sets of connecting frames, the second spiral strip is mounted on the second rotating shaft, the slider is slidably mounted on the front end of the base plate, the screw is rotatably mounted on the base plate, and the screw and slider are threaded together. The two sets of connecting rods are rotatably mounted on the slider, and each set of connecting rods is rotatably connected to a set of connecting frames. By rotating the screw and threadedly engaging the slider, the slider moves. As the slider moves, it pushes the connecting rod, which in turn pushes the connecting frame, thereby causing the connecting frame to engage with the second rotating shaft to clamp the second spiral strip onto the welding wire.

[0010] Preferably, the synchronization mechanism includes two sets of synchronous pulleys and a synchronous belt. The two sets of synchronous pulleys are respectively mounted on shaft one and shaft two, and the synchronous belt is mounted on the two sets of synchronous pulleys. The synchronous pulleys and the synchronous belt enable the two sets of shaft one and shaft two to rotate synchronously.

[0011] Preferably, the drive mechanism includes a motor and two sets of bevel gears. The motor is mounted on the front end of the base plate, and the two sets of bevel gears are respectively mounted on a set of rotating shafts and the output end of the motor, and the two sets of bevel gears mesh. By turning on the motor, the bevel gears are driven to rotate, and while the bevel gears are rotating, the meshing of the two sets of bevel gears drives the rotating shaft to rotate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the welding wire is limited by the limiting mechanism, the welding wire is clamped by the clamping mechanism, the drive mechanism is opened for driving, and the wire is fed by the wire feeding mechanism. At the same time, the wire feeding mechanism and the clamping mechanism are synchronized with each other to achieve synchronous transportation. Thus, during the wire feeding process of the welding machine, the material is accurately conveyed by friction transportation of the welding wire, and the friction is increased to prevent the material from slipping.

Detailed Implementation

[0014] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example

[0015] like Figures 1 to 4 As shown, a wire feeding device for a welding machine includes a limiting mechanism 1, two sets of wire feeding mechanisms 2, a pressing mechanism 3, two sets of synchronization mechanisms 4, and a driving mechanism 5. The two sets of wire feeding mechanisms 2 are mounted on the limiting mechanism 1, the pressing mechanism 3 is mounted on the limiting mechanism 1, the two sets of synchronization mechanisms 4 are mounted on the pressing mechanism 3 and the two sets of wire feeding mechanisms 2, and the driving mechanism 5 is mounted on the limiting mechanism 1. The limiting mechanism 1 limits the movement, the wire feeding mechanism 2 feeds the wire, the pressing mechanism 3 presses the wire, the synchronization mechanism 4 synchronizes the movement, and the driving mechanism 5 drives the movement. The limiting mechanism 1 includes a base plate 11 and a guide wire tube 12, with the guide wire tube 12 mounted on the base plate 11; The wire feeding mechanism 2 includes a rotating shaft 21 and a spiral strip 22. The rotating shaft 21 is rotatably mounted on the base plate 11, and the spiral strip 22 is mounted on the rotating shaft 21. The clamping mechanism 3 includes two sets of connecting frames 31, a second rotating shaft 32, a second spiral strip 33, a slider 34, a screw 35, and two sets of connecting rods 36. The two sets of connecting frames 31 are rotatably mounted on the base plate 11, the second rotating shaft 32 is rotatably mounted on the two sets of connecting frames 31, the second spiral strip 33 is mounted on the second rotating shaft 32, the slider 34 is slidably mounted on the front end of the base plate 11, the screw 35 is rotatably mounted on the base plate 11, and the screw 35 is threadedly engaged with the slider 34. The two sets of connecting rods 36 are rotatably mounted on the slider 34, and each set of connecting rods 36 is rotatably connected to a set of connecting frames 31. Synchronization mechanism 4 includes two sets of synchronous pulleys 41 and synchronous belt 42. The two sets of synchronous pulleys 41 are respectively mounted on shaft 21 and shaft 32, and synchronous belt 42 is mounted on the two sets of synchronous pulleys 41. The drive mechanism 5 includes a motor 51 and two sets of bevel gears 52. The motor 51 is mounted on the front end of the base plate 11, and the two sets of bevel gears 52 are respectively mounted on a set of rotating shafts 21 and the output end of the motor 51, and the two sets of bevel gears 52 mesh. The welding wire is limited by the guide tube 12. The slider 34 is moved by the screw 35 through the threaded engagement of the rotating screw 35. As the slider 34 moves, it pushes the connecting rod 36, which in turn pushes the connecting frame 31. This causes the connecting frame 31 to engage with the rotating shaft 32, which in turn clamps the welding wire with the spiral strip 33. The motor 51 is turned on to drive the bevel gear 52 to rotate. As the bevel gear 52 rotates, the meshing of two sets of bevel gears drives the rotating shaft 21 to rotate. At the same time, the synchronous pulley 41 and the synchronous belt 42 make the two sets of rotating shafts 21 and 32 rotate synchronously. The rotating shaft 21 drives the spiral strip 22 to rotate, which performs friction transport on the welding wire. The spiral shape of the spiral strip 22 facilitates transport and movement, and increases friction. Thus, during the wire feeding process of the welding machine, the material is accurately conveyed by friction transport of the welding wire, and the increased friction prevents the material from slipping.

[0016] like Figures 1 to 4 As shown, this utility model discloses a wire feeding device for a welding machine. During operation, the wire guide tube 12 limits the welding wire. A rotating screw 35 engages with a slider 34 via a threaded connection, causing the slider 34 to move. Simultaneously, the slider 34 pushes a connecting rod 36, which in turn pushes a connecting frame 31. This causes the connecting frame 31, in conjunction with a rotating shaft 32, to clamp the welding wire with a spiral strip 33. A motor 51 drives a bevel gear 52, causing it to rotate. Simultaneously, the meshing of two sets of bevel gears 52 drives a rotating shaft 21 to rotate. A synchronous pulley 41, in conjunction with a synchronous belt 42, causes both sets of rotating shafts 21 and 32 to rotate synchronously. The rotating shaft 21 drives the spiral strip 22 to rotate, providing frictional transport of the welding wire. The spiral shape of the spiral strip 22 facilitates transport and movement while increasing friction.

[0017] The motor 51 of this utility model is purchased from the market. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0018] The main function achieved by this utility model is: during the wire feeding process of the welding machine, by setting up a wire feeding mechanism and a clamping mechanism, the material is accurately conveyed through frictional transport of the welding wire during the wire feeding process of the welding machine, and the friction is increased to prevent the material from slipping.

[0019] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
