Description

Technical Field

[0001] The utility model mainly relates to the technical field of wire feeders, and in particular to a multi-angle rotating wire feeder for welding equipment. Background Art

[0002] The wire feeder is a very important part of the welding process. Traditional manual welding methods mostly use the welder's fingers to twist the wire to complete the wire feeding process. It is very inconvenient for the welder to operate the wire, with poor accuracy, low efficiency, and potential safety hazards. The existing three-dimensional robot laser welding is used to assemble a wire feeder on the robot for welding. Compared with manual welding, it effectively improves work efficiency and welding quality, and reduces safety hazards. However, the three axes or one axis of the welding robot are usually equipped with only one wire feeder. The wire speed is not stable during the wire feeding process, which easily leads to poor welding effects.

[0003] For example, Chinese patent publication number CN214518105U discloses a welding device with adjustable wire feeding angle, including an electric welding machine, wherein the output end of the electric welding machine is connected to a guide mechanism, the guide mechanism includes a guide bracket, a guide wheel group is rotatably provided on the guide bracket, and a welding wire channel is provided in the guide wheel group; the guide bracket is detachably connected to a wire feeding bracket, and a wire feeding nozzle is provided on the wire feeding bracket.

[0004] The above application adds a wire guide mechanism that can adjust the wire feeding angle to the wire feeding mechanism of the electric welding machine, so that the wire can change the wire feeding direction to avoid friction between the welding wire and the wire feeding nozzle, which may cause the welding wire to break and affect the normal welding work. However, the wire feeding direction is not easy to adjust. In some welding tasks, it is necessary to change the wire feeding angle to obtain the best welding effect. If the equipment cannot be adjusted at multiple angles, it may limit the operator's operating flexibility and fail to achieve ideal welding parameters. During the welding process, the wire feeding angle has an important influence on the formation and quality of the weld. A fixed wire feeding angle may not be able to adapt to different welding positions and joint shapes, resulting in uneven welds, defects and other problems, thereby affecting the strength and durability of the weld.

Example

[0032] See attached Figures 1 to 7 A multi-angle rotating wire feeding device for welding equipment comprises a frame 1, a wire feeder 2 is arranged on the frame 1, a wire feeding reel 3 is arranged on one side of the wire feeder 2, and an adjusting mechanism 4 is arranged on the other side, a welding wire 5 is wound on the wire feeding reel 3, the adjusting mechanism 4 comprises a mounting plate 41 fixed on the frame 1, an adjusting plate 42 is rotatably mounted on the mounting plate 41, the adjusting plate 42 is connected to an angle adjusting mechanism 43, the angle adjusting mechanism 43 is used to adjust the inclination angle of the adjusting plate 42, a height adjusting mechanism 44 is arranged on the adjusting plate 42, a wire feeding nozzle 45 is arranged on the output end of the height adjusting mechanism 44, and the welding wire 5 is sent to the adjusting mechanism 4 under the action of the wire feeder 2.

[0033] The wire feeder 2 includes two symmetrically arranged support frames 21, and a first wire feeder 23, a connecting ring 24, and a second wire feeder 25 connected to each other are sequentially arranged between the two support frames 21 from the inlet end to the outlet end. The support frames 21 and the connecting ring 24 are provided with feeding holes 22. The first wire feeder 23 and the second wire feeder 25 have the same structure. The second wire feeder 25 is the same as the first wire feeder 23 after rotating ninety degrees. The first wire feeder 23 includes a mounting frame 231, and a plurality of feeding wheels are rotatably arranged on the mounting frame 231. The feeding wheels include an active roller 232 and a driven roller 233, and the welding wire 5 passes between the active roller 232 and the driven roller 233.

[0034] The angle adjustment mechanism 43 includes a first support 431 fixed on the mounting plate 41, a first screw rod 432 is threadedly mounted on the first support 431, one end of the first screw rod 432 is fixedly connected to the adjustment handle 434, and the other end is movably connected to the connector 433, the lower end of the adjustment plate 42 is rotatably mounted on the mounting plate 41 through a rotating shaft 435, and the upper end thereof is movably connected to the connector 433 through a connecting column 436. A first guide groove 437 is provided on the adjustment plate 42, a first guide column 438 is fixedly mounted on the mounting plate 41, and the first guide groove 437 is sleeved on the first guide column 438.

[0035] The operator rotates the adjustment handle 434. Since the adjustment handle 434 is fixedly connected to one end of the first screw rod 432, the rotation of the adjustment handle 434 will drive the first screw rod 432 to rotate. The first screw rod 432 is connected to the first support 431 through a thread, and will produce axial movement when rotating. The movement of the first screw rod 432 will drive the connector 433 to move, and the movement of the connector 433 will drive the upper end of the adjustment plate 42 to move. Since the lower end of the adjustment plate 42 is mounted on the mounting plate 41 through the rotating shaft 435, the adjustment plate 42 will rotate around the rotating shaft 435. The rotation of the adjustment plate 42 will change the angle between it and the mounting plate 41, thereby affecting the output angle of the entire angle adjustment mechanism 43. The setting of the guide groove 437 and the first guide column 438 ensures that the adjustment plate 42 moves along a predetermined path. By rotating the adjustment handle 434, the operator can finely adjust the angle of the adjustment plate 42 until the desired angle position is reached.

[0036] The height adjustment mechanism 44 includes a mounting block 441 fixed on the adjustment plate 42, a second support 442 is fixedly mounted on the mounting block 441, a second screw 443 is threadedly mounted on the second support 442, the second screw 443 is movably connected to the lifting block 444, and the wire feeder 45 is mounted on the lifting block 444. A second guide groove 445 is provided on the mounting block 441, and a second guide column 446 is provided on the lifting block 444, and the second guide column 446 is slidably mounted in the second guide groove 445.

[0037] When the height of the wire feeding nozzle 45 needs to be adjusted, the second screw rod 443 can be rotated. Since the second screw rod 443 is movably connected to the lifting block 444, the lifting block 444 will move up and down with the rotation of the second screw rod 443, and the second guide groove 445 is designed to guide the movement of the second guide column 446 to ensure that the lifting block 444 moves along a predetermined path, thereby driving the wire feeding nozzle 45 to move up and down, and realizing the function of height adjustment.

[0038] Working principle:

[0039] The wire feeder 2 ensures that the welding wire 5 remains stable during the wire feeding process, reduces fluctuations and shaking, and improves the accuracy of wire feeding through the cooperation of the support frame 21, the first wire feeder 23, the connecting ring 24 and the second wire feeder 25. The support frame 21 and the connecting ring 24 are provided with a feeding hole 22, which plays a role in transmitting the wire feeding power and also provides a smooth transition path for the welding wire. The first wire feeder 23 and the second wire feeder 25 include a plurality of feeding wheels, which are composed of an active roller 232 and a driven roller 233. The welding wire 5 is pulled through under the action of the friction force of the active roller 232 and the driven roller 233. At the same time, the arrangement directions of the first wire feeder 23 and the second wire feeder 25 are perpendicular to each other. The active roller 232 and the driven roller 233 can also straighten the welding wire 5 in two directions during the feeding process, thereby ensuring that the welding wire 5 is straight.

[0040] The welding wire 5 on the wire feeding disc 3 is sent to the adjusting mechanism 4 under the action of the wire feeding machine 2, and the inclination angle of the adjusting plate 42 is adjusted by the angle adjusting mechanism 43, so as to adjust the wire feeding angle, and the height adjusting mechanism 44 is used to adjust the height of the wire feeding nozzle 45, so that the wire feeding nozzle 45 is at a suitable height to adapt to different welding positions. Since the wire feeding angle and height can be adjusted, the utility model can adapt to various welding environments and requirements, and has strong adaptability. Through multi-angle adjustment, the formation of the weld can be stabilized, the molten pool can be controlled, and better welding quality can be obtained. The use of the adjusting mechanism 4 can make the operation more convenient, reduce the adjustment time and labor intensity, and improve the work efficiency.

[0041] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
