[0034] like Figures 1 to 3 As shown, this embodiment provides a welding auxiliary device, which includes a base 10, a connecting member 20, a clamping assembly 40 and a supporting member 30. The first end of the connecting member 20 is connected to the base 10, and the second end of the connecting member 20 can swing around the first end; the clamping assembly 40 is rotatably connected to the second end of the connecting member 20, and the clamping assembly 40 is used to clamp the workpiece to be welded. The two ends of the supporting member 30 are respectively connected to the base 10 and the connecting member 20, and are used to support and position the connecting member 20.

[0035] The first end of the connecting member 20 is connected to the base 10, and the second end is connected to the clamping assembly 40. The second end of the connecting member 20 can swing around the first end, so as to adjust the position of the clamping assembly 40, that is, adjust the position of the workpiece to be welded. By setting the support member 30, the support member 30 can support and position the connecting member 20, so that the connecting member 20 can remain stationary in a specific position after adjustment, which is helpful to complete the welding operation. The angle of the workpiece to be welded can be adjusted by rotating the clamping assembly 40, thereby improving the versatility of the welding auxiliary device to meet the usage requirements in different welding scenarios.

[0036] Specifically, the base 10 includes a base 11 and a column 12, the base 11 is used to support on the ground, the column 12 is arranged on the base 11, the connecting member 20 is connected to the top of the column 12, and the support member 30 is rotatably connected with the base 11 and the connecting member 20. By setting the base 11, the base 11 is supported and fixed on the ground, which helps to ensure the stability of the welding auxiliary device and avoid the welding auxiliary device from shifting during the welding process, thereby affecting the welding quality. By setting the column 12 on the base 11 and setting the connecting member 20 at the top of the column 12, the connecting member 20 and the clamping assembly 40 can adapt to the actual required use height.

[0037] In this embodiment, the base 11 is fixed to the ground by bolts, the column 12 is fixed to the base 11, and the axis direction of the column 12 is perpendicular to the upper surface of the base 11; the column 12 extends in the vertical direction; the base 10 is made of steel material. Optionally, the column 12 can be set as an electric lifting column or a telescopic column.

[0038] The base 10 is made of steel material, such as stainless steel or high-temperature alloy material, which has high strength and corrosion resistance, is easy to install and can maintain good performance in a humid environment. The column 12 can be raised or lowered or retracted to adjust the distance between the top of the column 12 and the ground, thereby adapting to welding scenes of different heights.

[0039] The first end of the connecting member 20 is rotatably connected to the top of the column 12, and the second end of the connecting member 20 can swing around the first end, so that the axis direction of the connecting member 20 forms an angle with the axis direction of the column 12, and the angle ranges from 45° to 180°. Figure 1 At this time, the axial direction of the connecting member 20 is perpendicular to the axial direction of the column 12, and the connecting member 20 extends in the horizontal direction.

[0040] In order to better adjust the clamping assembly 40, the clamping assembly 40 is rotatably connected to the second end of the connecting member 20 via a rotating structure 50. The rotating structure 50 can be a bearing or other mechanical structure. By adopting the rotating structure 50 for connection, the angle adjustment range of the clamping assembly 40 is increased, for example, the clamping assembly 40 can be freely rotated 360 degrees, thereby freely adjusting the angle of the workpiece to be welded.

[0041] Furthermore, the support member 30 can make the connection member 20 swing to achieve positioning. In this embodiment, the support member 30 is a hydraulic rod, and the two ends of the hydraulic rod are respectively rotatably connected to the base 10 and the connection member 20. The hydraulic rod can be extended and retracted and maintain a certain length to position the second end of the connection member 20. By setting the hydraulic rod, the hydraulic rod is controlled to be extended and retracted, thereby supporting the connection member 20 and pushing the connection member 20 to swing. After adjusting the connection member 20, the hydraulic rod maintains its length, thereby positioning the connection member 20. In other embodiments, an electric push rod or the like can also be used as the support member 30.

[0042] See also Figure 1 The first end of the hydraulic rod is rotatably connected to the base 11, the second end of the hydraulic rod is rotatably connected to the connecting piece 20, and the distance between the first end of the hydraulic rod and the axis of the column 12 is smaller than the distance between the second end of the hydraulic rod and the axis of the column 12. By setting the positions of the two ends of the hydraulic rod, the hydraulic rod can be extended from bottom to top in a direction close to the column 12, which can reduce the telescopic stroke of the hydraulic rod during use and help ensure the stability of the support of the connecting piece 20.

[0043] See also Figure 2 and Figure 3 The clamping assembly 40 includes a clamping base plate 41 and a clamping auxiliary plate 43 which are arranged opposite to each other. The clamping base plate 41 is rotatably connected to the connecting member 20 through a rotating structure 50. The clamping auxiliary plate 43 is connected to the clamping base plate 41. The distance between the clamping auxiliary plate 43 and the clamping base plate 41 is adjustable for clamping the parts to be welded.

[0044] By setting the clamping base plate 41 and the clamping auxiliary plate 43, both the plates to be welded and the pipes to be welded can be clamped; by setting the adjustable spacing between the clamping auxiliary plate 43 and the clamping base plate 41, the versatility of the clamping assembly 40 is improved, and it can be applicable to plates of different thicknesses and pipes of different outer diameters.

[0045] In this embodiment, the clamping assembly 40 also includes an adjustment plate 42 and a fastener 44. The clamping auxiliary plate 43 is rotatably connected to the adjustment plate 42 and is rotatably connected to the clamping base plate 41 through the adjustment plate 42 to adjust the distance between the clamping auxiliary plate 43 and the clamping base plate 41. The fastener 44 is threadedly connected to the clamping auxiliary plate 43 and the clamping base plate 41.

[0046] By setting the adjustment plate 42, rotating the adjustment plate 42 can change the position of the clamping auxiliary plate 43 relative to the clamping base plate 41, and by rotating and adjusting the clamping auxiliary plate 43, the clamping auxiliary plate 43 can be made parallel to the clamping base plate 41, thereby controlling the distance between the clamping auxiliary plate 43 and the clamping base plate 41; the clamping auxiliary plate 43 and the clamping base plate 41 are fixed by the fastener 44, and the clamping auxiliary plate 43 and the clamping base plate 41 can be controlled to maintain a specific distance, and the connection is stable and firm and has strong adjustability. In other embodiments, the clamping assembly 40 can also be set as a magnetic clamping or spring clamping structure.

[0047] In order to improve the stability of clamping, multiple clamping auxiliary plates 43 are arranged side by side at intervals, and the adjustment plate 42 is arranged one by one with the clamping auxiliary plates 43; at least two fasteners 44 are arranged between the clamping base plate 41 and each clamping auxiliary plate 43; the fasteners 44 can be bolts. By setting multiple clamping auxiliary plates 43, the parts to be welded can be clamped from different positions, which can not only improve the stability of clamping, but also use different clamping auxiliary plates 43 to clamp the thin area and thick area of ​​the same pipe, or the large end and small end of the same pipe, which is more applicable. By setting at least two fasteners 44 on each clamping auxiliary plate 43, the stability of the connection is enhanced, ensuring that after the fasteners 44 are fixed, the clamping auxiliary plate 43 and the clamping base plate 41 will not shift or deflect.

[0048] The following are specific usage scenarios of welding auxiliary devices:

[0049] The welding auxiliary device can be applied to welding methods such as flat welding, horizontal welding, vertical welding and overhead welding. Among them, flat welding refers to the welding process in which the welding position is in a horizontal position or at a small inclination angle, the welding rod is located above the workpiece, and the welder looks down at the workpiece; horizontal welding is the welding of the horizontal weld on a vertical or inclined plane. Vertical welding refers to the welding of the vertical weld on a vertical plane; overhead welding refers to the welding position below the horizontal.

[0050] See also Figure 1 and Figure 3 Taking the plate to be welded as an example, the connecting member 20 extends in the horizontal direction, and the clamping base plate 41 and the clamping auxiliary plate 43 of the clamping assembly 40 can clamp the plate and keep the plane where the plate is located horizontal. If the welding position is above the plate, it is flat welding, and if the welding position is below the plate, it is overhead welding. The clamping assembly 40 can be used to drive the plate to rotate to adjust the welding position.

[0051] If Figure 1 Based on the neutral state, the clamping assembly 40 is rotated to keep the plane of the plate vertical. If the weld is welded along the vertical direction, it is vertical welding, and if the weld is welded along the horizontal direction, it is horizontal welding. The connecting piece 20 can be swung to adjust the welding position. It is understandable that the specific welding method needs to be selected according to the specific situation, and the connecting piece 20 and the clamping assembly 40 are adjusted according to the welding method to apply to a variety of different welding scenarios.

[0052] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
