[0037] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0038] like Figures 1 to 5 An auxiliary positioning device suitable for U-shaped clamp welding processing includes a bearing base plate 1, which is different in that: a vertically distributed vertical plate 2 is installed on the bearing base plate 1, and a limiting component is installed on the vertical plate 2 to limit the U-shaped clamp 15, which is convenient for temporary positioning during subsequent welding. At the same time, the upper end of the limiting component is movably connected with an upper positioning component 3, and the lower end of the limiting component is connected with a lower positioning component 4. In this way, the upper positioning component 3 can be relied on, and the limiting component exists to meet the temporary positioning needs during the welding of the two reinforcement plates 16. In addition, in order to prevent unnecessary displacement of the reinforcement plate 16 and improve the welding accuracy, the upper positioning component 3 and the lower positioning component 4 are both provided with independent limiting mechanisms 5. Furthermore, in order to facilitate the downward plug-in positioning needs of the U-shaped clamp 15 during subsequent processing, the upper positioning component 3 and the lower positioning component 4 do not contact the vertical plate 2 at one end thereof, forming a plug-in space. In this way, the U-shaped clamp 15 can be limited and temporarily placed and guided through the plug-in space.

[0039] In combination with a preferred embodiment of the present invention, the limiting components used are the limiting side plates 6 distributed in pairs, and the spacing between the limiting side plates 6 corresponds to the width of the U-shaped clamp 15, which can be slightly larger than the width of the U-shaped clamp 15, so as to facilitate smooth insertion and removal without causing jamming. In addition, the limiting side plates 6 are connected to the vertical plates 2 by positioning screws to achieve convenient positioning. During implementation, other connection methods can also be used, which will not be repeated here.

[0040] Further, the upper positioning assembly 3 used includes a connection frame, and side wings 7 extend from both ends of the connection frame, and the side wings 7 are connected to the limit assembly through a rotating shaft 8. In this way, the upper positioning assembly 3 can achieve appropriate rotation, and after welding is completed, the reinforcing sheet 16 is given way to facilitate the U-shaped clamp 15 to be smoothly pulled out and separated from the limit assembly after welding. At the same time, in order to temporarily limit the reinforcing sheet 16 distributed at the upper end, the connection frame extends an upper limit plate 9 in the direction of the vertical plate 2, and a limit mechanism 5 is distributed on the upper limit plate 9. In addition, the edge of the upper limit plate 9 is distributed with arc chamfers, which will not scratch the U-shaped clamp 15. Furthermore, the upper limit plate 9 does not contact the vertical plate 2, forming a contact gap, which is larger than the thickness of the U-shaped clamp 15, so as to facilitate the smooth insertion and removal of the U-shaped clamp 15 during processing.

[0041] In view of the actual implementation, the lower positioning component 4 is a Z-shaped folding plate, which presents a stepped structure, which is convenient for the subsequent positioning of the lower end. The upper end of the Z-shaped folding plate constitutes the lower positioning plate 10, and the limiting mechanism 5 is distributed on the lower positioning plate 10. At the same time, the lower positioning plate 10 is not in contact with the vertical plate 2, and also constitutes a contact gap. In addition, the lower end of the Z-shaped folding plate constitutes a mounting plate 11, and the mounting plate 11 is connected to the bearing base plate 1 through a mounting mechanism. Specifically, the mounting mechanism includes an oblong adjustment groove 12 mirror-distributed on the mounting plate 11, and a fixing hole is provided at a corresponding position of the bearing base plate 1, and a fixing screw 13 is connected to the adjustment groove 12 and the fixing hole. In this way, during actual installation, the width of the contact gap can be adjusted to adapt to the thickness of the U-shaped clamp 15 and meet the needs of fine-tuning the connection. Furthermore, the edges of the lower positioning plate 10 are distributed with arc chamfers, and the U-shaped clamp 15 will not be scratched.

[0042] Further, in order to temporarily limit the reinforcing sheet 16 appropriately, the limiting mechanism 5 is a limiting column. At the same time, its height exceeds the thickness of the reinforcing sheet 16 to achieve appropriate blocking. In addition, the limiting column is provided with a contact plane toward the vertical plate 2, which can fit one side of the reinforcing sheet 16. During implementation, a circular chamfer can be provided on the top of the limiting column to prevent sharp parts from scratching the operator.

[0043] At the same time, in order to meet the effective placement level and avoid unnecessary skewing when the reinforcing sheet 16 is welded, a plurality of adjustable feet 14 are installed at the lower end of the bearing base plate 1. Specifically, the adjustable feet 14 include guide columns distributed at the lower end of the bearing base plate 1 and extending downward, the guide columns are provided with threaded holes, the guide columns are threadedly connected with screws, and the ends of the screws are threadedly connected with pads. In this way, after being placed in place, the actual height difference can be adjusted by the screws to ensure an effective working level.

[0044] The working principle of the present invention is as follows:

[0045] Insert the U-shaped clamp 15 with the inner side facing outward into the limit assembly. The outer edge of the U-shaped clamp 15 contacts the vertical plate 2 and is inserted into the preset analysis. Finally, one end of the U-shaped clamp 15 contacts the load-bearing bottom plate 1. At this time, the user can check the upper positioning assembly 3 to ensure that the upper limit plate 9 is in a horizontal position.

[0046] Afterwards, the two reinforcing plates 16 are placed on the upper limiting plate 9 and the lower positioning plate 10 respectively, and are temporarily limited by the corresponding limiting mechanisms 5 .

[0047] Then, by welding, the reinforcing sheet 16 is combined with the U-shaped hoop 15. During this period, the user does not need to temporarily limit the reinforcing sheet 16 by holding a positioning tool such as a clip in one hand, and the welding operation is more convenient.

[0048] After the welding is completed, the U-shaped clamp 15 can be separated smoothly by just pulling it upwards. During this period, the reinforcing sheet 16 at the lower end will press against the upper positioning assembly 3, allowing it to rotate along the rotating shaft 8 to open and give way. After that, the user can manually flip and reset it.

[0049] It can be seen from the above textual description and the accompanying drawings that the present invention has the following advantages:

[0050] 1. The upper positioning assembly and the lower positioning assembly can realize temporary positioning of the two reinforcement plates during welding, ensuring accurate welding without skewness, which is convenient for strengthening the force of the subsequent U-shaped clamp.

[0051] 2. Through the limit assembly, the U-shaped clamp can be placed and positioned by plugging and unplugging, which is convenient to use and does not affect the placement accuracy.

[0052] 3. The upper positioning component adopts a flip combination method, which can meet the requirements of removal and clearance after welding without the user's active operation.

[0053] 4. It is equipped with adjustable feet, which can realize horizontal calibration after placement, ensure the position accuracy of the reinforcement plate welding, and realize effective force bearing.

[0054] 5. The overall structure is simple, easy to manufacture and use, and the implementation cost is low.

[0055] In addition, the indicated orientations or positional relationships described in the present invention are all based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or structure referred to must have a specific orientation or be operated with a specific orientation structure. Therefore, they cannot be understood as limitations on the present invention.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
