[0002] The welding machine is equipped with a wire feeding mechanism to continuously feed wire to the welding gun to achieve automated welding. The existing wire feeding mechanism consists of a wire feeding wheel and a pressure wheel. The welding wire is pressed against the wire feeding wheel by the pressure wheel. During the rotation of the wire feeding wheel, the welding wire is driven to move by friction, thereby continuously feeding the wire.

[0003] Common wire feeding mechanism correction components are set in small quantities, so their adjustability is not high, and they cannot guarantee stability and good correction when they are adjusted and expanded to accommodate thicker wires. Therefore, when corresponding to thicker wires, due to poor stability and correction, the quality of the wire will be poor, which may cause poor welding and waste of wire. In order to address the above technical problems, the correction components are enriched, so a wire feeding device that reduces additive loss is proposed. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5A wire feeding device for reducing additive loss includes a guide ring 1 and a wire body 5. A plurality of correction wheels 4 are arranged in the guide ring 1. An annular movable chamber 6 and an annular rotating chamber 8 are arranged inside the guide ring 1. A plurality of screws 7 extending into the annular rotating chamber 8 are arranged in the annular movable chamber 6. A transmission ring 10 is arranged in the annular rotating chamber 8 through a limiting mechanism. A drive motor 14 is arranged in the annular rotating chamber 8. The drive motor 14 is connected to the transmission ring 10 through a rotating mechanism. The transmission ring 10 is connected to the screw 7 through a transmission mechanism. The correction wheel 4 is connected to the correction wheel 4 through a connecting mechanism.

[0023] The limiting mechanism includes a limiting ring 11 installed on the transmission ring 10, and an annular limiting groove corresponding to the limiting ring 11 is provided on the inner wall of the annular rotating chamber 8. The cross-sectional views of the limiting ring 11 and the annular limiting groove are both L-shaped. The limiting ring 11 is in the annular limiting groove to ensure the stable position of the transmission ring 10, so that it can rotate stably in the annular rotating chamber 8.

[0024] The rotating mechanism includes a driving gear 15 arranged on the output shaft of the driving motor 14, and a driving ring gear 13 is provided on the transmission ring 10. The driving gear 15 meshes with the driving ring gear 13. The transmission mechanism includes a transmission gear 9 arranged on the end of the screw 7, and a transmission ring gear 12 is provided on the transmission ring 10. The transmission gear 9 meshes with the transmission ring gear 12. The positions of the transmission ring gear 12 and the driving ring gear 13 are shown in the accompanying drawings, and their teeth are not drawn, which can achieve meshing with the driving gear 15 and the transmission gear 9.

[0025] The connecting mechanism includes a connecting frame 3 which is arranged in the annular rotating cavity 8 and threadedly mounted on the screw 7. The connecting frame 3 is U-shaped and is rotatably connected to the correction wheel 4. The connecting frame 3 has two branches which both slide through the inner wall of the annular rotating cavity 8 and extend to the outside of the guide ring 1. Therefore, it has its own limit and will not rotate with the screw 7.

[0026] There are three correction wheels 4 , which are evenly spaced around the circumference. The circumferential distribution ensures that the correction force on the wire 5 is uniform.

[0027] When the utility model is used, when the wire 5 passes through the guide ring 1, it is corrected by the three correction wheels 4, so that the wire 5 is changed from a bent state to a straight state when it is turned out from the wire reel. The spacing between the three correction wheels 4 can be flexibly adjusted, so as to adapt to wires 5 of various models and sizes within a certain range. Specifically: start the drive motor 14, the drive motor 14 drives the active gear 15 to rotate, the active gear 15 can drive the transmission ring 10 to rotate with the help of the active gear ring 13, the transmission ring 10 can drive the screw 7 to rotate with the help of the transmission gear ring 12 and the transmission gear 9, and when the screw 7 rotates, the connecting frame 3 threadedly mounted thereon will move, thereby driving the correction wheel 4 to move to achieve spacing adjustment.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
