Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and in particular to a welding fixture for reducing tees. Background Technology

[0002] In the manufacturing process of flow batteries, the construction of the piping system is crucial, as the reliability and stability of its connections directly affect the performance and lifespan of the flow battery. Among these processes, the welding of reducing tees to pipe fittings is one of the key steps in the fabrication of flow battery piping. During welding, the reducing tees must be welded to the pipe fittings with the axis of the equal-diameter pipe extending vertically. Existing hot-melt equipment is insufficient to meet these fixing requirements.

[0003] Currently, reducing tees and pipe fittings are typically welded manually. During the hot-melt stage, due to the material properties and the gap in the hot-melt mold, operators need to manually align the reducing tees and pipe fittings and exert considerable force to push the welded components inward, making the operation quite difficult. Initially, operators have ample energy, and welding efficiency can be maintained at a certain level. However, as working time increases, operators gradually become exhausted, and welding efficiency drops sharply, resulting in a long welding process, low efficiency, and unstable product quality. Furthermore, during manual welding, operators are in close contact with the hot-melt equipment for extended periods, posing a high risk of burns and significant safety hazards.

[0004] Therefore, there is an urgent need to propose a welding fixture for reducing tees to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a welding fixture for reducing tees to meet the fixing requirements when welding reducing tees to pipe fittings, reduce the difficulty of operation, reduce labor costs, improve production efficiency and product quality stability, and ensure personal safety.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A welding fixture for reducing tees includes a support component, a connector, a base, a pressure plate, and at least two limiting components;

[0008] The base and the pressure plate are vertically opposite to each other on the bearing surface of the bearing member, and are both movably connected to the bearing member. The base is used to support one end of the equal diameter pipe of the reducing tee, and the pressure plate is used to abut against the other end of the equal diameter pipe, thereby pressing and fixing the reducing tee onto the base.

[0009] At least two of the limiting members are arranged opposite each other in the horizontal direction on the bearing surface, and are movably connected to the bearing member. The limiting members are used to abut against the side wall of the equal diameter pipe.

[0010] The connector is located on the side of the carrier opposite to the bearing surface and is used to connect to the hot melt equipment.

[0011] Furthermore, the width of both the base and the pressure plate is greater than the width of the limiting member.

[0012] Furthermore, both the base and the pressure plate are vertically adjustable to the support member.

[0013] Furthermore, the reducing tee welding fixture also includes at least two first locking members. The base and the pressure plate both include a first adjusting part and a first abutting part connected at an angle. The first abutting part is used to abut against the end of the equal diameter pipe. The first adjusting part has a first adjusting groove extending in the vertical direction. The first locking member passes through the first adjusting groove, and one end is connected to the bearing member. The other end can press and fix the first adjusting part to the bearing member.

[0014] Furthermore, the base includes at least two first adjustment portions spaced apart in the horizontal direction.

[0015] Furthermore, the height of the first abutment portion is greater than the wall thickness of the equal-diameter pipe.

[0016] Furthermore, at least two of the limiting members are arbitrarily connected to the limiting members in a horizontal direction.

[0017] Furthermore, the reducing tee welding fixture also includes at least two second locking members. The limiting member includes a second adjusting part and a second abutting part connected at an included angle. The second abutting part is used to abut against the side wall of the equal diameter pipe. The second adjusting part has a second adjusting groove extending in the horizontal direction. The second locking member passes through the second adjusting groove, and one end is connected to the bearing member. The other end can press and fix the second adjusting part to the bearing member.

[0018] Furthermore, the height of the second abutment portion is greater than the outer radius of the equal-diameter tube.

[0019] Furthermore, the connector is a hollow cylinder.

[0020] The beneficial effects of this utility model are:

[0021] This utility model provides a welding fixture for reducing tees, including a support member, a connector, a base, a pressure plate, and at least two limiting members. The base and the pressure plate are vertically opposite to each other on the support surface of the support member and are movably connected to the support member. The base is used to support one end of the equal-diameter pipe of the reducing tee, and the pressure plate is used to abut against the other end of the equal-diameter pipe, thereby pressing and fixing the reducing tee onto the base. At least two limiting members are horizontally opposite to each other on the support surface of the support member and are movably connected to the support member. The limiting members abut against the side wall of the equal-diameter pipe, thereby restricting the position of the reducing tee in the horizontal direction. By clamping the side wall of the equal-diameter pipe with the limiting members, the reducing tee can be erected on the support surface to facilitate the connection between the reducing end and the pipe fitting. The aforementioned reducing tee welding fixture uses a base and pressure plate to vertically clamp and fix the equal-diameter pipe of the reducing tee. This vertical clamping of the reducing tee meets the fixing requirements when welding the reducing tee to the pipe fitting, replacing manual operation. Furthermore, the positional distribution of the base, pressure plate, and limiting components is set according to the structure and size of the reducing tee, ensuring alignment between the reducing end and the pipe fitting. This reduces the difficulty of operation, lowers labor costs, improves production efficiency and product quality stability, and ensures personal safety. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0031] like Figure 1 and Figure 2As shown, this embodiment provides a welding fixture for reducing tees, including a carrier 1, a connector 2, a base 3, a pressure plate 4, and at least two limiting members 5; the base 3 and the pressure plate 4 are vertically opposite to each other on the bearing surface of the carrier 1, and are both movably connected to the carrier 1. The base 3 is used to support one end of the equal diameter pipe 110 of the reducing tee 100, and the pressure plate 4 is used to abut against the other end of the equal diameter pipe 110, thereby pressing and fixing the reducing tee 100 onto the base 3; at least two limiting members 5; Positioning members 5 are arranged horizontally opposite each other on the bearing surface of bearing member 1, and are movably connected to bearing member 1. The limiting member 5 is used to abut against the side wall of equal diameter pipe 110, thereby limiting the position of reducing tee 100 in the horizontal direction. By clamping the side wall of equal diameter pipe 110 with limiting member 5, reducing tee 100 can be erected on bearing surface, so as to facilitate the connection between reducing end and pipe fitting. Connecting member 2 is arranged on the side of bearing member 1 opposite to bearing surface, and is used to connect to hot melt equipment. Using the aforementioned reducing tee welding fixture, the equal-diameter pipe 110 of the reducing tee 100 is clamped and fixed vertically by the base 3 and the pressure plate 4. This converts the horizontal clamping of the reducing tee 100 by the hot melt equipment into vertical clamping, which can meet the fixing requirements when welding the reducing tee 100 to the pipe fitting, replacing manual operation. Furthermore, the positional distribution of the base 3, pressure plate 4, and limiting member 5 is set according to the structure and size of the reducing tee 100, which can ensure that the reducing end is aligned with the pipe fitting, reduce the difficulty of operation, reduce labor costs, improve production efficiency and product quality stability, and ensure the personal safety of workers.

[0032] The width of both the base 3 and the pressure plate 4 is greater than the width of the limiting member 5, which ensures the contact area between the base 3 and the pressure plate 4 and the equal diameter pipe 110. This is beneficial to improving the load-bearing capacity of the base 3 and the clamping stability of the base 3 and the pressure plate 4 on the reducing tee 100, thereby ensuring the welding effect.

[0033] In this embodiment, two limiting members 5 are arranged opposite each other in the horizontal direction on the bearing surface of the bearing member 1 to form a set of limiting structures to clamp the side wall of the equal diameter pipe 110. In other embodiments, two, three or five sets of limiting structures may also be arranged at intervals in the vertical direction on the bearing surface, which is not limited here.

[0034] Furthermore, both the base 3 and the pressure plate 4 are vertically adjustable to the support 1. The operator can adaptively adjust the vertical position of the base 3 and the pressure plate 4 according to the length of the equal diameter pipe 110 and the position of the reducer 120 on the equal diameter pipe 110, so as to clamp the equal diameter pipe 110 and keep the axis of the reducer 120 in a preset position, thereby keeping it aligned with the pipe joint.

[0035] Specifically, the reducing tee welding fixture also includes at least two first locking elements 6. The base 3 and the pressure plate 4 both include a first adjusting part 7 and a first abutting part 8 connected at an angle. The first abutting part 8 is used to abut against the end of the equal diameter pipe 110, which facilitates the vertical positioning of the reducing tee 100. The first adjusting part 7 has a first adjusting groove extending in the vertical direction. The first locking element 6 passes through the first adjusting groove, and one end is connected to the bearing 1. The other end can press and fix the first adjusting part 7 onto the bearing 1. The first adjusting groove of the first adjusting part 7, in conjunction with the first locking element 6, can be adjusted in the vertical direction to adapt to different pipe lengths. The first locking element 6 can press and fix the pressure plate 4 or the base 3 to ensure the stability of the fixture during welding. Its overall structure is simple, easy to operate, and highly practical.

[0036] Furthermore, the base 3 includes at least two first adjustment parts 7 spaced apart in the horizontal direction. These at least two first adjustment parts 7 can provide multi-point fixation for the base 3, preventing the base 3 from rotating around the first locking member 6. They can also effectively distribute the weight and welding stress of the reducing tee 100, enhance the connection stability between the tooling and the reducing tee 100, and prevent shaking or tilting during welding. In addition, the first adjustment parts 7 of the base 3 and the pressure plate 4 can be adjusted independently or collaboratively to adapt to the installation requirements of reducing tees 100 with different structures and sizes, achieve more precise positioning, make the welding position more accurate, and improve the welding quality.

[0037] Furthermore, the height of the first abutting part 8 is greater than the wall thickness of the equal diameter tube 110, which can ensure the contact area between the first abutting part 8 and the equal diameter tube 110, thereby ensuring clamping stability.

[0038] Optionally, at least two limiting members 5 are connected to the limiting member 5 in a horizontally adjustable manner. By adjusting the position of the limiting member 5 in the horizontal direction, the limiting requirements of equal diameter pipes 110 of different diameters can be met, further improving the versatility of the welding tooling for reducing tees.

[0039] Specifically, the welding fixture for reducing tees also includes at least two second locking elements 9. The limiting element 5 includes a second adjusting part 10 and a second abutting part 11 connected at an angle. The second abutting part 11 is used to abut against the side wall of the equal diameter pipe 110. The second adjusting part 10 has a second adjusting groove extending in the horizontal direction. The second locking element 9 passes through the second adjusting groove, and one end is connected to the bearing element 1. The other end can press and fix the second adjusting part 10 to the bearing element 1. The second adjusting groove of the second adjusting part 10, in conjunction with the second locking element 9, can be adjusted in the horizontal direction to adapt to different pipe diameters. The second locking element 9 can press and fix the limiting element 5 to ensure the stability of the fixture during welding. Its overall structure is simple, easy to operate, and highly practical.

[0040] The first locking element 6 and the second locking element 9 include, but are not limited to, screws or studs, etc., which are not limited here.

[0041] Furthermore, the height of the second abutment portion 11 is greater than the outer radius of the equal diameter tube 110, which can ensure that the clamping forces of the two limiting members 5 on the equal diameter tube 110 are opposite in the horizontal direction, avoiding the formation of an angle between them, thereby improving the clamping stability of the reducing tee 100 in the horizontal direction.

[0042] Of course, in other alternative embodiments, the connection method between the first adjustment part 7 and the second adjustment part 10 and the carrier 1 includes, but is not limited to, snap-fit, and is not limited here.

[0043] In addition, the connector 2 is a hollow cylinder that is compatible with the clamping end of the hot melt equipment and can be clamped between the jaws of the hot melt equipment. Setting the connector 2 as a hollow cylinder helps to reduce manufacturing costs and tooling weight while ensuring the structural strength of the tooling.

[0044] Furthermore, the support member 1 is a disc coaxial with the connector 2, and the diameter of the support member 1 is larger than the diameter of the connector 2, which facilitates the connection between the support member 1 and the connector 2 and provides a larger bearing area, thus providing space for the installation of the pressure plate 4, the base 3 and the limiting member 5.

[0045] The bearing component 1 and the connecting component 2 are connected by welding, which helps to improve the structural stability of the reducing tee welding fixture and increase its load-bearing capacity.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
