Technical Field

[0001] The utility model relates to the technical field of welding auxiliary tools, in particular to a novel steel bar bracket used for welding. Background Art

[0002] More and more welded parts are widely used in the industrial field. At present, welding platforms are usually used to fix and install workpieces, and welding is achieved by welding machines. Such welding machines are in an unconstrained state, and there are problems such as difficult to ensure welding position, difficult positioning, and no clamping. At the same time, during the welding process, welders usually need to adjust their posture to achieve operations such as flat welding, horizontal welding, vertical welding, and overhead welding. Being in this working state for a long time does not conform to the principles of ergonomics and is prone to fatigue, thus causing operational errors and safety accidents.

[0003] When welding structural parts with complex shapes and irregular shapes, it is necessary to weld different surfaces of the structural parts. For example, when welding the inclined surface on the structural part, the welder needs to adopt different postures to weld the inclined surface, which increases the labor intensity of the operator. In addition, when welding the inclined surface, the inclined surface is in an inclined state, and the liquefied structural parts may flow during the welding process, resulting in a decrease in welding quality.

[0004] Therefore, in the prior art, there is a technical problem that the bevel cannot be straightened during the bevel welding process on the structural parts. Summary of the invention

In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0037] Reference Figures 1 to 6 As shown, a new type of steel bar support for welding comprises a bearing assembly 1 of a bearing fixture and a frame 2, wherein the bearing assembly 1 is rotatably connected to the frame 2, and an angle adjustment assembly 3 for adjusting the angle of the bearing assembly 1 relative to the frame 2 is provided between the frame 2 and the bearing assembly 1;

[0038] The angle adjustment assembly 3 includes a worm wheel 31 fixed to the bearing assembly 1, the frame 2 is provided with a worm 32 matched with the worm wheel 31, the worm 32 is rotatably connected to the frame 2, and the axis of the worm wheel 31 coincides with the rotating axis 21 of the bearing assembly 1;

[0039] The bearing assembly 1 is provided with an indicator 11 for indicating an angle between the bearing assembly 1 and the frame 2 .

[0040] In some embodiments, the indicator 11 can be a bubble tube, which can be bonded to the supporting component 1. The bubble tube can indicate the horizontal state, so that when the supporting component 1 is in the horizontal state, it can be indicated by the indicator 11, which is beneficial to the operation of the angle adjustment component 3 and can conveniently adjust the supporting component 1 to the horizontal state.

[0041] In some embodiments, the supporting assembly 1 includes a supporting plate 12 and a rotating drum 13, a connecting rod 14 is arranged between the supporting plate 12 and the rotating drum 13, the supporting plate 12 is provided with an arc plate 15 fixedly connected to the connecting rod 14, and the arc plate 15 and the supporting plate 12 are an integrated structure.

[0042] The arc-shaped plate 15 is used to connect the connecting rods 14 , so that more connecting rods 14 can be arranged between the bearing plate 12 and the rotary drum 13 , thereby improving the strength of the bearing assembly 1 and preventing the bearing assembly 1 from being deformed or damaged.

[0043] Reference Figures 1 to 6 As shown, in some embodiments, one end of the connecting rod 14 is welded to the rotating drum 13, and the other end of the connecting rod 14 is welded to the arc plate 15. The frame 2 is provided with a rotating shaft 21 that cooperates with the rotating drum 13, and the axis of the worm gear 31 coincides with the axis of the rotating shaft 21.

[0045] The connecting rod 14 can also be fixed to the arc plate 15 and the rotating drum 13 by screws. The fixing method of the connecting rod 14 is not limited and can be reasonably designed according to needs. Generally, when welding is adopted, the connection strength of the connecting rod 14, the arc plate 15 and the rotating drum 13 is high and not easy to be misaligned, so that the bearing assembly 1 has higher precision.

[0050] In practice, when the supporting plate 12 has a certain angle relative to the horizontal plane, it may be more conducive to welding. Therefore, in some embodiments, the indicator 11 is a scale line, and the scale line is arranged on the arc plate 15.

[0051] The scale line can effectively indicate the angle of the support plate 12 relative to the horizontal plane. At the same time, the worm wheel 31 and the worm 32 enable the angle of the support plate 12 to be steplessly adjusted, thereby improving the adjustment accuracy of the angle adjustment component 3.

[0052] In some embodiments, the scale lines are recessed into the arc plate 15. The scale group is recessed into the arc plate 15 so that the scale lines are not easily worn, thereby extending the service life of the scale lines.

[0053] In some embodiments, the worm gear 31 and the carrier plate 12 are an integrated structure, and the worm gear 31 is located in the middle of the length direction of the carrier plate 12. The worm gear 31 can also be fixed to the carrier plate 12 by a detachable connection, for example, the worm gear 31 can be fixed to the carrier plate 12 by screws.

[0054] Since the angle of the bearing plate 12 only needs to be adjusted within a certain angle, the worm gear 31 can be semicircular, or an arc larger than a semicircle, or an arc smaller than a semicircle.

[0055] Reference Figures 1 to 6 As shown, in some embodiments, the frame 2 is provided with a mounting plate 22 for mounting the worm 32, and extension shafts are provided at both ends of the worm 32. The mounting plate 22 is provided with an axial hole 221 that cooperates with the extension shaft.

[0056] A rolling bearing is provided between the extension shaft and the shaft hole 221 , and the rolling bearing is a deep groove ball bearing. The mounting plate 22 is welded to the frame 2 .

[0057] The mounting plate 22 can be welded to the frame 2, or the mounting plate 22 can also be fixed to the frame 2 by screws.

[0058] In some embodiments, the supporting plate 12 is provided with mounting grooves 121 for mounting fixtures, and the mounting grooves 121 are evenly distributed on one surface of the supporting plate 12 .

[0059] In some embodiments, the frame 2 may be formed by welding steel bars, or the frame 2 may be formed by welding steel plates.

[0060] In some embodiments, the arc-shaped plate 15 and the connecting rod 14 can be made of steel bars.
