Description

Technical Field

[0001] This utility model relates to the field of pipe fitting processing technology, and more specifically to an auxiliary device for pipe fitting processing. Background Technology

[0002] Pipe fittings are a general term for components in a piping system that serve functions such as connection, control, direction change, flow diversion, and sealing. In existing technologies, when welding pipe fittings together, spacers are often used as support devices. That is, spacers are used to support and raise the height of the pipe fitting so that it can be connected to the pipe end of another pipe fitting, thereby ensuring the stability of the welding process.

[0003] However, using shims to support pipe fittings is inconvenient. When a pipe fitting needs a certain height, multiple shims of different thicknesses need to be stacked to connect it with the pipe opening of another pipe fitting. In this process, not only are multiple shims of different thicknesses required, but the accuracy of the pipe opening connection between pipe fittings cannot be guaranteed. Summary of the Invention

[0004] The purpose of this utility model is to provide a pipe fitting processing auxiliary device that can effectively support and adjust the pipe fittings, facilitate the connection between two pipe fittings, and improve the efficiency and quality of pipe fitting welding.

[0005] Therefore, this utility model provides a pipe fitting processing auxiliary device, including a support assembly, a connecting rod assembly, the connecting rod assembly being mounted on the support assembly, the connecting rod assembly including a rotatable and vertically movable connecting rod; and a roller assembly, the roller assembly being fixed to the top of the connecting rod, the roller assembly including two symmetrically arranged roller groups, each of the two roller groups including multiple rollers, and the planes containing the central axes of the multiple rollers of the two roller groups forming an included angle.

[0006] The connecting rod assembly includes a connecting part, the bottom of which is connected to a guide tube, and the bottom of the connecting rod extends from the connecting part into the guide tube.

[0007] Preferably, the support assembly includes at least two support rods, the tops of the at least two support rods are fixed to the outer wall of the connecting part, and the bottoms of the at least two support rods are located on the same plane.

[0008] Preferably, the roller assembly includes a base plate, which is fixed to the connecting bar and is perpendicular to the axial direction of the connecting bar.

[0009] Preferably, the roller assembly includes a mounting bracket on which the roller is rotatable.

[0010] Preferably, the mounting bracket includes two spaced-apart first mounting plates, each of which is vertically provided with a second mounting plate; the two second mounting plates are parallel to each other, and the roller is rotatably mounted between the two second mounting plates.

[0011] Preferably, a limiting plate is connected between the tops of the two first mounting plates, the limiting plate forming an angle with the first mounting plates, and the limiting plate extending toward the roller.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This utility model provides an auxiliary device for pipe processing. The rotation of the connecting rod can drive the roller assembly to rotate, and the up-and-down movement of the connecting rod can drive the roller assembly to move up and down. Placing the pipe between two roller assemblies provides limiting support for the pipe. The up-and-down movement and rotation of the roller assembly can drive the pipe to move up and down and rotate around the top of the connecting rod, thereby adjusting the height of the pipe from the ground and the orientation of the pipe to facilitate processing. Furthermore, the rotation of multiple rollers allows the pipe to rotate around its central axis, enabling processing of different parts of the pipe.

[0013] When the pipe fitting processing auxiliary device of this embodiment is used to support the pipe fitting, the pipe fitting can also be leveled so that multiple pipe fittings can be on the same horizontal plane, thereby facilitating the docking between two adjacent pipe fittings and improving the welding processing quality and processing efficiency of the pipe fittings.

[0014] Other features and advantages of this utility model will become clearer after reading the detailed embodiments of this utility model in conjunction with the accompanying drawings. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1-5 As shown, the pipe fitting processing auxiliary device of this utility model includes a support assembly and a connecting rod assembly. The connecting rod assembly is mounted on the support assembly and includes a connecting rod 10 that can move up and down. Two roller assemblies are symmetrically mounted on the top of the connecting rod 10. The roller assembly includes multiple rollers 20, and the plane containing the central axes of the multiple rollers 20 of the two roller assemblies forms an included angle.

[0022] Rotation of the connecting rod 10 drives the rotation of the two roller assemblies as a whole (the two roller assemblies rotate around the connecting rod 10). The up-and-down movement of the connecting rod 10 drives the up-and-down movement of the two roller assemblies as a whole. Placing the pipe fitting between the two roller assemblies provides limiting support. The up-and-down movement and rotation of the roller assemblies allow the pipe fitting to move up and down and rotate around the connecting rod 10, thereby adjusting the height of the pipe fitting from the ground and its orientation for easier processing. Furthermore, rotation of the roller 20 allows the pipe fitting 10 to rotate around its own central axis, facilitating the processing of different parts of the pipe fitting.

[0023] In practical applications, one, two, three or more pipe processing auxiliary devices of this embodiment can be used to support and adjust the pipes according to their length and weight, without making specific limitations.

[0024] When the pipe fitting processing auxiliary device of this embodiment is used to support the pipe fitting, the pipe fitting can also be leveled so that multiple pipe fittings can be on the same horizontal plane, thereby facilitating the docking between two adjacent pipe fittings and improving the welding processing quality and processing efficiency of the pipe fittings.

[0025] The plane containing the central axes of the multiple rollers 20 in one roller assembly is the first plane, and the plane containing the central axes of the multiple rollers 20 in the other roller assembly is the second plane. The first and second planes form an included angle α. The included angle α can be an acute angle, a right angle, or an obtuse angle, and there is no specific limitation here. The size of the included angle α can be set according to the diameter of the pipe to be processed, as long as it can effectively support the pipe by the two roller assemblies.

[0026] The connecting rod assembly includes a connecting part 11, which can be cylindrical or cuboid in shape, without specific limitations. The connecting part 11 has a cavity. The connecting rod 10 can be a threaded rod. A bolt 13 can be fixedly installed in the cavity of the connecting part 11. The bolt 13 has a threaded hole 14. The connecting rod 10 is threaded into the threaded hole 14, thereby allowing the connecting rod 10 to move up and down while rotating.

[0027] The bottom of the connecting part 11 is connected to a guide tube 12, and the bottom of the connecting rod 10 extends from the connecting part 11 into the guide tube 12. The connecting rod 10 rotates and moves up and down within the connecting part 11 and the guide tube 12. The guide tube 12 can guide and limit the rotation and up and down movement of the connecting rod 10, and can also protect the connecting rod 10 to prevent it from being scratched, ensuring that the connecting rod 10 can rotate and move up and down stably and effectively.

[0028] Alternatively, in other preferred embodiments, the connecting rod assembly may further include a motor for driving the connecting rod 10 to rotate and move up and down, without specific limitations.

[0029] The support assembly includes at least two support rods 30, the tops of which are fixed to the outer wall of the connecting part 11, and the bottoms of which are located on the same plane.

[0030] In this embodiment, the number of support rods 30 can be three. The bottom of the three support rods 30 abuts against the ground, and the top of the three support rods 30 is fixed to the connecting part 11. The three support rods 30 are evenly distributed and fixed on the connecting part 11 at equal intervals.

[0031] The three support rods 30 can form a triangular structure, which can provide stable and effective support, thus ensuring that the pipe fitting processing auxiliary device of this embodiment is stably and effectively supported on the ground. In addition, it also makes the overall pipe fitting processing auxiliary device of this embodiment lightweight, making it easy to transport and move.

[0032] In other preferred embodiments, the number of support rods 30 may be 2, 4, 5, 6, or more, without any specific limitation.

[0033] The roller assembly includes a base plate 21, which is fixed to the connecting rod 10 and is perpendicular to the axis of the connecting rod 10.

[0034] The base plate 21 can be welded to the top of the connecting bar 10 or fixed in other ways, without specific restrictions.

[0035] The projection of the base plate 21 can be rectangular. The bottom center of the base plate 21 is fixed to the top of the connecting rod 10, so that the connecting rod 10 is subjected to uniform force and the connecting rod assembly can provide stable and effective support for the roller assembly.

[0036] The roller assembly includes a mounting bracket on which the roller 20 is rotatably mounted.

[0037] Specifically, the mounting bracket includes two spaced-apart first mounting plates 22, which are respectively fixed to both ends of the base plate 21.

[0038] Specifically, bottom mounting plates 25 are fixed to both ends of the base plate 21, and the bottom mounting plates 25 are horizontally positioned. The bottom of the first mounting plate 22 is fixed to the bottom mounting plate 25, and the first mounting plate 22 and the bottom mounting plate 25 form an angle. By setting the bottom mounting plate 25, the force on the connecting rod 10 can be distributed, the support strength of the connecting rod 10 can be improved, and the connecting rod 10 can be prevented from being bent by the pipe fitting.

[0039] The top surfaces of the two first mounting plates 22 are each vertically provided with a second mounting plate 23. The two second mounting plates 23 are parallel to each other. A roller 20 is rotatably mounted between the two second mounting plates 23. The axis of the roller 20 is perpendicular to the second mounting plate 23.

[0040] The top surface of the roller 20 protrudes from the top of the second mounting plate 23, thereby ensuring that the pipe can contact the surface of the roller 20. The roller 20 can effectively support the pipe. Through the rotation of the roller 20 itself, the pipe can be driven to rotate around its central axis.

[0041] A limiting plate 24 is connected between the tops of the two first mounting plates 22. The limiting plate 24 forms an angle with the first mounting plate 22 and extends towards the roller 20. The two limiting plates 24 are arranged opposite to each other to limit the pipe fitting and prevent it from detaching from the pipe assembly and rolling off.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by this utility model.
