Description

Technical Field

[0001] This utility model relates to a welding wire position adjustment device, belonging to the field of welding technology. Background Technology

[0002] The wire position adjustment device is a core component of automated tungsten inert gas (TIG) welding, used to adjust the position of the fed welding wire. Its importance is particularly pronounced in confined spaces, directly determining welding accessibility, process stability, and operational safety. Traditional wire feeders, due to their large size, motion interference, or vibration sensitivity, can cause wire path deviation, uneven wire feeding, or even jamming in confined spaces, leading to arc interruption and welding failure. Furthermore, in confined spaces, the welding area typically suffers from obstructed vision, limited operational freedom, and poor heat dissipation. Therefore, the design of the wire feed adjustment device must address multiple challenges, including space constraints, heat dissipation difficulties, electromagnetic interference, and limited operational visibility. Utility Model Content

[0003] The purpose of this invention is to provide a welding wire position adjustment device that can achieve multi-degree-of-freedom adjustment, has a compact structure, is easy to adjust, improves welding quality, and solves the above-mentioned problems existing in the background art.

[0004] The technical solution of this utility model is:

[0005] A welding wire position adjustment device includes a first motor, a first worm gear, a first turbine gear, a screw, a second motor, a second worm gear, and a second turbine gear. The screw has a first turbine gear and a second turbine gear, which are threadedly connected to the screw. The first turbine gear meshes with the first worm gear, and the first motor is mounted on the first worm gear. The second turbine gear meshes with the second worm gear, and the second motor is mounted on the second worm gear. The second turbine gear has a flat hole at its center, and the screw has a platform that matches the flat hole. Both the first and second turbine gears are fixed by bearings and are rotatable. A wire feed rod is mounted at the lower end of the screw. The first motor drives the first worm gear to rotate, which in turn drives the first turbine gear to rotate, causing the screw to move up and down. The second motor drives the second worm gear to rotate, which in turn drives the second turbine gear to rotate. The second turbine gear, constrained by the platform on the screw, causes the screw to rotate synchronously. The screw's movement drives the wire feed rod, thereby adjusting the wire feed position.

[0006] The screw is provided with an upper fixing block and a lower fixing block, and turbine one and turbine two are both located between the upper fixing block and the lower fixing block.

[0007] The lower end of the screw is provided with a clamping block, and a feed screw is installed on the clamping block.

[0008] The number of bearings is four, with one set on the top and one on the bottom of turbine one, and one set on the top and one on the bottom of turbine two.

[0009] The motor one, bearings, and motor two mentioned above are all devices that are known and commonly used in this field.

[0010] When this invention is in operation, motor one drives worm gear one to rotate, which in turn drives worm gear one meshing with it to rotate. Since worm gear one is threadedly connected to the screw, and its height is fixed by bearings, it can only rotate. At this time, the screw moves up and down. Motor two drives worm gear two to rotate, which in turn drives worm gear two meshing with it to rotate. Worm gear two is fixed up and down by bearings, and it can only rotate. Since the screw has a platform limitation, it will drive the screw to rotate synchronously. Through the above structure, the screw height and rotation angle can be controlled separately, which drives the clamping block at the lower end of the screw to move and realize the adjustment of the wire feeding position.

[0011] The beneficial effects of this utility model are: it can achieve multi-degree-of-freedom adjustment, has a compact structure, is easy to adjust, and improves welding quality. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and examples.

[0019] A welding wire position adjustment device includes a motor 701, a worm gear 702, a turbine gear 703, a screw 705, a second motor 706, a second worm gear 707, and a second turbine gear 708. The screw 705 is equipped with the first turbine gear 703 and the second turbine gear 708. The first turbine gear 703 and the screw 705 are threadedly connected. The first turbine gear 703 meshes with the first worm gear 702, and the first motor gear 701 is mounted on the first worm gear 702. The second turbine gear 708 meshes with the second worm gear 707, and the second motor gear 706 is mounted on the second worm gear 707. The second turbine gear 708 has a flat hole at its center, and the screw 705 has a corresponding flat hole. A matching platform is used; both turbine 1 703 and turbine 2 708 are fixed by bearing 704, and turbine 1 703 and turbine 2 708 are rotatable; a feed screw is installed at the lower end of screw 705; motor 1 701 drives worm 1 702 to rotate, worm 1 702 drives turbine 1 703 to rotate, causing screw 705 to move up and down; motor 2 706 drives worm 2 707 to rotate, worm 2 707 drives turbine 2 708 to rotate, and turbine 2 708 is restricted by the platform on screw 705 to drive screw 705 to rotate synchronously; the movement of screw 705 drives the feed screw to move, thereby realizing the adjustment of the feed position.

[0020] The screw 705 is provided with an upper fixing block 709 and a lower fixing block 710, and turbine one 703 and turbine two 708 are both arranged between the upper fixing block 709 and the lower fixing block 710.

[0021] The lower end of the screw 705 is provided with a clamping block 711, and a thread feeder is installed on the clamping block 711.

[0022] There are four bearings 704, one on the top and one on the bottom of turbine 1 703, and one on the top and one on the bottom of turbine 2 708.

[0023] In this embodiment, refer to the appendix. Figure 1-5 Between the upper fixing block 709 and the lower fixing block 710, a bearing 704, a turbine 703, two bearings 704, a turbine 708, and a bearing 704 are arranged sequentially from top to bottom. The screw 705 is installed at the center of the above parts. The turbine 703 and the worm 702 mesh with each other, and the motor 701 is installed on the worm 702. The turbine 708 and the worm 707 mesh with each other, and the motor 706 is installed on the worm 707. The lower end of the screw 705 is provided with a clamping block 711 for installing the lead screw.

[0024] The screw 705 has a diameter of C and a platform with a width of B machined around its circumference; the turbine 703 has a circular threaded hole at its center, which is an MC thread with a diameter of C, and the screw 705 is an MC screw, with the turbine 703 and the screw 705 threadedly connected; the turbine 708 has a flat hole at its center with a width of B, through which the screw 705 passes; during operation, the motor 701 drives the worm gear 702 to rotate, thereby driving the meshing turbine 703 to rotate. Since the turbine 703 is fixed vertically by the bearing 704, it can only rotate. 03 is threadedly connected to screw 705. The height of turbine 703 is fixed by bearing 704, at which time screw 705 moves up and down. Motor 2 706 drives worm gear 2 707 to rotate, thereby driving turbine 2 708, which meshes with it, to rotate. Turbine 2 708 can only rotate after being fixed up and down by bearing 704. When turbine 2 708 rotates, it will drive screw 705 to rotate synchronously due to the platform limitation of width B of screw 705. Through the above structure, the screw height and rotation angle are controlled separately, which drives the clamping block 711 at the lower end of screw 705 to move, thereby realizing the adjustment of the wire feeding position.

[0025] This utility model can be used in pairs. The two sets of this utility model are respectively set on both sides of the welding gun holder 5. The welding gun holder is connected to the welding carriage 1. Wire feeding devices 2 are respectively set on both sides of the welding carriage 1. Each set of wire feeding devices 2 is equipped with a wire straightening mechanism 21. The welding wire is conveyed by the wire feeding device, straightened by the wire straightening mechanism 21, and then the wire feeding position is adjusted by the wire position adjustment device 7.

[0026] This invention allows for easy adjustment of the wire feeding path when working in confined spaces, ensuring uniform wire feeding. Its reasonable structure avoids problems such as heat dissipation difficulties, electromagnetic interference, and limited operating visibility, thus guaranteeing smooth welding and improving welding quality.
