It should be understood that the data used in this way can be interchanged where appropriate, so as to describe the embodiments of the utility model described herein. In addition, similar terms such as "including" and "having" mean that in addition to those contents already listed in "including" and "having", other contents that have not been listed can also be "included" and "having"; for example, a process, method, system, product or device that can include a series of steps or units is not necessarily limited to those steps or units that have been clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0022] Due to the angle of the drawing, some components may not be drawn, but their positions and connection relationships can be partially understood based on the text expression.

[0023] like Figure 1 As shown, the utility model is an auxiliary device for welding and positioning a single pipe on an arc surface part, comprising a magnetic base 1, a round pipe positioning frame 3 connected to the side of the magnetic base 1, and a bolt 4 installed on the round pipe positioning frame 3.

[0024] The round tube positioning frame 3 comprises a first positioning plate 3-1, a second positioning plate 3-2, a transition plate 3-3 and a bolt plate 3-4 which are connected in sequence. A positioning angle is formed between the first positioning plate 3-1 and the second positioning plate 3-2, and the bolts 4 are connected to the bolt plate 3-4.

[0025] In order to facilitate the rotation of the bolt 4, the head of the bolt 4 is located outside the round tube positioning frame 3, and the tail of the bolt 4 faces the positioning angle.

[0026] In order to increase the contact area with the pipe joint 6 and improve the fixing strength of the pipe joint 6, a pressure head 5 is installed at the tail of the bolt 4, and the end surface of the pressure head 5 contacting the pipe joint 6 is an arc surface.

[0027] In order to protect the outer surface of the pipe joint 6, a rubber pad 8 is installed inside the positioning angle.

[0028] The positioning angle is between 60° and 90°, which is convenient for positioning the pipe joint 6 .

[0029] The side surface of the magnetic base 1 is connected to the round tube positioning frame 3 by welding process.

[0030] The top of the magnetic base 1 is provided with a switch 2 for controlling the magnetic circuit of a metal switch, and the bottom of the magnetic base 1 is a V-shaped surface, which can better adsorb and fit on the curved surface parts.

[0031] The working process of the utility model is as follows:

[0032] First, install the pipe joint 6 into the round tube positioning frame 3, close to the rubber material surface of the inner angle of the pipe clamp, adjust it so that the center of the pipe joint is vertically distributed with the center of the tightening screw, then turn on the magnetic switch 2 of the magnetic base 1, connect the magnetic circuit, and make the V-shaped block at the bottom of the magnetic base 1 adsorb on the arc surface part 7 near the pipe hole. After pre-positioning one side of the pipe joint 6, adjust the bolt 4 according to the actual pipe diameter of the pipe joint 6, so that the pressure head 5 compacts the outer surface of the pipe joint 6 without gap. At this time, the pipe joint 6 has been firmly positioned at the position of the pipe hole, and the operator can easily perform spot welding to fix the pipe. After the operation is completed, unscrew the bolt 4, turn on the magnetic switch 2, disconnect the magnetic circuit, and take out the device.
