Therefore, they should not be construed as limitations on this application.

[0023] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale; for example, the thickness or width of some layers may be exaggerated relative to other layers.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0025] In order to solve the technical problems in the background art, such as Figure 1-2 As shown, this application provides a technical solution: a pipe welding positioning device, characterized as follows:

[0026] The fixed base 1 is an integral structure with two side surfaces 2 and a bottom surface 3. The two side surfaces 2 and the bottom surface 3 are adjacent to each other, forming a stable support platform. A symmetry axis passing through the apex of the fixed base 1 is provided on the bottom surface 3 to ensure the symmetry and stability of the device. The operating slot 4 is located at the apex of the fixed base 1 and is formed by square notches reserved on the two side surfaces 2 and the bottom surface 3. This design allows workers to easily place the pipe in the operating slot 4 when welding pipes, simplifying the operation steps. Multiple adjusting feet 5 are evenly arranged in the triangular positions of the bottom surface 3 and adopt a telescopic structure, which can be extended and retracted in the vertical direction. The height of the adjusting feet 5 can be adjusted according to the needs of the working environment to accommodate pipe welding operations at different heights. The fixing block 6 is located at the central axis of the bottom surface 3 and shares a common symmetry axis with the bottom surface 3. The fixing block 6 has a threaded hole 7 provided axially inside for screwing in the adjusting screw 8. This design ensures that the fixing block 6 can provide stable support during welding. The adjusting screw 8 is connected to the fixing block 6 through the threaded hole 7 and can rotate within the threaded hole 7. The rotation of the adjusting screw 8 allows for precise control of the adjusting block 9, thereby adjusting the clamping force and position of the pipe. The adjusting block 9 is symmetrical about the bottom surface 3 and has side walls 10 parallel to the two side surfaces 2. The adjusting block 9 is connected to the fixed block 6 via the adjusting screw 8. Driven by the adjusting screw 8, the adjusting block 9 can move along the side surface 2 to clamp the horizontal pipe. The design of the adjusting block 9 ensures uniformity and stability of the clamping.

[0027] It should be noted that the extension bracket 11 is disposed on the side 2 of the fixed base 1 to extend the function and applicability of the device. The extension bracket 11 is designed with an inclined surface 14 perpendicular to the axis of symmetry of the bottom surface 3. The inclined surface 14 is located on the extension bracket 11 and is perpendicular to the axis of symmetry of the bottom surface 3. A through hole 15 is provided on the inclined surface 14, which is collinear with the axis of symmetry of the bottom surface 3 to ensure the symmetry and stability of the device. An internal thread is provided in the through hole 15 for screwing in the adjusting rod 12. The design of the through hole 15 allows the adjusting rod 12 to rotate inside it. The adjusting rod 12 is screwed into the through hole 15, and its movement is driven by the thread. A V-block 13 is provided at one end of the adjusting rod 12 for cooperating with the two sides 2 of the fixed base 1 to clamp the vertical pipe. The V-block 13 is disposed at one end of the adjusting rod 12 for contacting the pipe and providing clamping force. The design of the V-block 13 helps to fix the pipe with a symmetrical shape and prevent it from rolling or moving during welding.

[0028] Furthermore, the included angle between the two side walls 10 of the V-block 13 is 90 degrees, which means that the V-block 13 is actually a right-angled V-block 13. This design provides a more stable clamping effect and is particularly suitable for clamping cylindrical and square pipes. The right-angle design of the V-block 13 enhances the clamping stability of the pipe and improves the versatility and practicality of the device.

[0029] It should be noted that the auxiliary foot 16 is located on the extension line of axis 3 on the bottom surface. The auxiliary foot 16 is designed to provide additional stability and support, especially when welding heavy or long pipes, as it prevents the device from tilting or moving. The design of the auxiliary foot 16 enhances the stability of the device, making it particularly suitable for welding heavy or long pipes, thus improving the practicality and safety of the device.

[0030] Furthermore, the auxiliary foot 16 is a telescopic structure, located on the extension line of axis 3 on the bottom surface. This design allows the length of the auxiliary foot 16 to be adjusted according to actual needs, to adapt to welding workbenches or ground conditions of different heights.

[0031] It should be noted that the guide rail 17 is disposed on the bottom surface 3 and is parallel to the axis of the bottom surface 3. The function of the guide rail 17 is to provide guidance for the adjusting block 9, ensuring the stability and accuracy of the adjusting block 9 during movement. The bottom of the adjusting block 9 has a groove 18 that is adapted to the guide rail 17. The design of the groove 18 allows the adjusting block 9 to slide smoothly along the guide rail 17, thereby achieving precise positioning and clamping.

[0032] It is worth noting that the guide rail 17 is set on the bottom surface 3 and parallel to the axis of the bottom surface 3. To ensure the stability and accuracy of the adjusting block 9 during movement, the two guide rails 17 are set in parallel and symmetrically along the axis of the bottom surface 3. This symmetrical layout provides balanced guidance, making the movement of the adjusting block 9 on both sides more stable and precise.

[0033] It should be noted that the rotary handle 19 is located at the end of the adjusting screw 8 and is perpendicular to the axis of the adjusting screw 8. The design of the rotary handle 19 allows the operator to manually rotate the adjusting screw 8, thereby controlling the movement of the adjusting block 9 and achieving clamping and positioning of the pipe.

[0034] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
