Description

Technical Field

[0001] This utility model relates to the technical field of copper pipe welding fixtures, and in particular to a copper pipe welding support device. Background Technology

[0002] Copper pipes are widely used in industries such as refrigeration, HVAC, power, and chemicals due to their excellent thermal conductivity, corrosion resistance, and machinability. In practical applications, it is often necessary to weld multiple copper pipes of different shapes, such as straight pipes and bent pipes, together to form complex piping assemblies. One typical component involves welding multiple vertical branch pipes or bent copper pipes with specific angles onto a long main copper pipe.

[0003] Currently, the common method for performing this type of welding is for the operator to manually position and support the copper pipe to be welded. Specifically, the main copper pipe needs to be positioned first, and then the end of the copper pipe to be welded, either vertical or bent, is manually aligned with the welding position on the main copper pipe. Spot welding and final welding are then performed in this state. This method has the following significant drawbacks:

[0004] First, positioning accuracy is difficult to guarantee. Relying entirely on the operator's experience and feel makes it difficult to ensure that the relative angle and spacing between the branch pipe and the main copper pipe, as well as the spatial posture of the bent copper pipe, remain consistent, resulting in unstable product quality and poor dimensional consistency within the same batch of workpieces.

[0005] Secondly, the welding efficiency is low. Because each branch pipe to be welded needs to be manually supported, it takes up a lot of manual time, and it is impossible to achieve synchronous positioning and welding of multiple branch pipes, resulting in low production efficiency and making it unsuitable for mass production.

[0006] Secondly, there are potential safety and quality risks. Manual support not only increases the risk of burns or arc burns to operators, but also, during the welding process, slight movement of the copper tube may lead to defects such as misalignment or incomplete fusion in the weld.

[0007] Although some general-purpose clamps exist on the market, they are usually single-function and cannot simultaneously meet the requirements of stable and precise coordinated positioning and support for main copper pipes, multiple vertical copper pipes at multiple ends, and complex-shaped bent copper pipes. In particular, they lack targeted designs for supporting the bent sections of the main copper pipes and supporting suspended bent branch pipes. Utility Model Content

[0008] The present invention aims to address the shortcomings of the prior art by providing a copper pipe welding support device.

[0009] To achieve the above objectives, this utility model adopts the following technical solution:

[0010] A copper pipe welding support device includes a base plate. Two columns are provided on the left and right sides of the upper surface of the base plate. A main copper pipe positioning groove is opened on the upper part of the front of the two columns. A positioning plate is fixed on the two columns. A vertical copper pipe welding positioning groove is opened on the left and right sides of the front of the positioning plate. A bent copper pipe welding positioning groove is opened in the middle of the front of the positioning plate. A first support column and a second support column are fixed between the bottom of the positioning plate and the base plate. The first support column and the second support column are respectively located on both sides of the bent copper pipe welding positioning groove. A bent section support plate of the main copper pipe is provided on the front of the first support column. A bent copper pipe support plate is provided on the front of the second support column. A main copper pipe end positioning seat is provided on the left side of the upper surface of the base plate. The main copper pipe to be welded is supported on the main copper pipe positioning groove and the bent section support plate of the main copper pipe. The end of the main copper pipe to be welded abuts against the main copper pipe end positioning seat. A first reinforcement support and a second reinforcement support are provided between the main copper pipe to be welded and the upper surface of the base plate. The first reinforcement support is located on one side of the main copper pipe end positioning seat. The second reinforcement support is located on one side of the bent copper pipe support plate.

[0011] The main copper tube end positioning seat has a positioning hole on its side wall, and the end of the main copper tube to be welded is inserted and installed in the positioning hole.

[0012] Both the first and second reinforcing supports have arc-shaped limiting grooves at their tops.

[0013] The number of vertical copper tube welding positioning grooves on the left and right sides of the positioning plate is two each.

[0014] The number of positioning slots for the bent copper tube in the middle of the positioning plate is two.

[0015] The bending copper tube support plate consists of two plates, one at the top and one at the bottom.

[0016] An inert gas connecting pipe is installed on the corresponding vertical copper pipe welding positioning groove and the bent copper pipe welding positioning groove at the top of the positioning plate. The inert gas connecting pipe is connected to the top opening of the corresponding vertical copper pipe and the bent copper pipe to be welded.

[0017] The beneficial effects of this utility model are as follows: This utility model integrates the positioning functions of the main copper tube to be welded, the vertical copper tube to be welded, and the bent copper tube to be welded into one device, ensuring the relative position accuracy between each component. Through end positioning, intermediate slot positioning, bottom support plate, and multiple reinforcement supports, a three-dimensional, multi-point fixing system is formed, which effectively suppresses welding deformation, has strong stability, and the multi-station design allows for the simultaneous positioning and welding of multiple components, thus improving production efficiency.

[0026] like Figures 1 to 2As shown, a copper pipe welding support device includes a base plate 1, a column 2, a main copper pipe positioning groove 3, a positioning plate 4, an end vertical copper pipe welding positioning groove 5, a bent copper pipe welding positioning groove 6, a first support column 7, a second support column 8, a main copper pipe bent section support plate 9, a bent copper pipe support plate 10, a main copper pipe end positioning seat 11, a first reinforcing support 12, a second reinforcing support 13, a positioning hole 14, and an arc-shaped limiting groove 15.

[0027] This utility model is used to accurately weld the main copper pipe 16 to be welded, the vertical copper pipe 17 to be welded, and the bent copper pipe 18 to be welded. Its core is that a modular positioning system is constructed by using the base plate 1, the column 2, the positioning plate 4 and multiple special support blocks / plates to ensure that all copper pipes to be welded are stably and accurately fixed in the designed position in three-dimensional space, thereby ensuring the welding quality and consistency.

[0028] The base plate 1 is the foundation of the entire device.

[0029] Two columns 2 are provided on the left and right sides of the upper surface of the base plate 1. The main copper pipe positioning groove 3 is opened on the upper part of the front of the two columns 2. The two columns 2 stand on both sides of the base plate 1, and the main copper pipe positioning groove 3 opened on their front is used to support and initially position the main copper pipe 16 to be welded.

[0030] Positioning plates 4 are fixed on the two columns 2. Positioning plates 4 have vertical copper tube welding positioning grooves 5 on the left and right sides of the front side. Positioning plates 3 have bent copper tube welding positioning grooves 6 in the middle of the front side.

[0031] The positioning plate 4 is fixed to the column 2 and is a key component for welding other copper pipes. Two types of positioning grooves are opened on its front side:

[0032] The vertical copper tube welding positioning groove 5 is located on the left and right sides and is used to position the vertical copper tube 17 extending vertically from the main copper tube 16 to be welded.

[0033] The welding positioning groove 6 of the bent copper tube is located in the middle and is used to position the bent copper tube 18 to be welded and connected to the main copper tube 16 to be welded.

[0034] The bottom of the positioning plate 3 is fixed with a first support column 7 and a second support column 8 between the bottom and the base plate 1. The first support column 7 and the second support column 8 are located on both sides of the welding positioning groove 6 of the bent copper tube. The front of the first support column 7 is provided with a main copper tube bending section support plate 9, and the front of the second support column 7 is provided with a bent copper tube support plate 10.

[0035] The main copper pipe 16 to be welded is supported on the main copper pipe positioning groove 3 and the main copper pipe bending section support plate 9.

[0036] The first support column 7 and the second support column 8 provide additional support on both sides of the welding positioning groove 6 of the bent copper tube.

[0037] The main copper tube bending section support plate 9 is specifically designed to support the bent portion of the main copper tube 16 to be welded, preventing it from sagging due to gravity.

[0038] The copper tube support plate 10 is used to support the copper tube 18 to be welded from below, ensuring its shape and position are stable.

[0039] The number of vertical copper tube welding positioning grooves 5 on the left and right sides of the positioning plate 4 is two each.

[0040] The number of the bent copper tube welding positioning grooves 6 in the middle of the positioning plate 4 is two.

[0041] The bent copper tube support plate 10 includes two plates, one at the top and one at the bottom.

[0042] The left side of the upper surface of the base plate 1 is provided with a main copper tube end positioning seat 11, and the end of the main copper tube 16 to be welded abuts against the main copper tube end positioning seat 11.

[0043] The main copper tube end positioning seat 11 has a positioning hole 14 on its side wall, and the end of the main copper tube 16 to be welded is inserted and installed in the positioning hole 14. The end of the main copper tube 16 to be welded is positioned by insertion through the positioning hole 14 on its side wall, which restricts the axial degree of freedom of the main copper tube 16 to be welded and ensures that its position in the length direction is accurate.

[0044] A first reinforcing support 12 and a second reinforcing support 13 are provided between the main copper tube 16 to be welded and the upper surface of the base plate 1. The first reinforcing support 12 is located on one side of the positioning seat 11 at the end of the main copper tube, and the second reinforcing support 13 is located on one side of the bent copper tube support plate 10.

[0045] Both the first reinforcing support 12 and the second reinforcing support 13 are provided with arc-shaped limiting grooves 15 at their top, which can better fit the pipe wall and provide additional intermediate support for the long-span main copper pipe 16 to be welded, preventing it from vibrating or deforming during the welding process.

[0046] The positioning plate 4 is equipped with an inert gas connecting pipe for each of the vertical copper pipe welding positioning groove 5 and the bent copper pipe welding positioning groove 6 at the top. The inert gas connecting pipe is connected to the top opening of the corresponding vertical copper pipe 17 and the bent copper pipe 18 to be welded. Inert gas (such as nitrogen or argon) can be introduced into the inner cavity of the copper pipe during welding, which can effectively prevent the inner wall of the pipe from oxidizing at high temperature and improve the welding quality.

[0047] This utility model integrates positioning: the positioning functions of the main copper tube 16 to be welded, the vertical copper tube 17 to be welded, and the bent copper tube 18 to be welded are integrated into one device to ensure the relative positional accuracy between the components.

[0048] This utility model has strong stability: through end positioning, middle groove positioning, bottom support plate and multiple reinforcement supports, a three-dimensional, multi-point fixing system is formed, which effectively suppresses welding deformation.

[0049] This invention is highly efficient: the multi-station design allows for the simultaneous positioning and welding of multiple components, thus improving production efficiency.

[0050] This invention can ensure welding quality: the design of the inert gas protection interface reflects the control of the internal quality of the weld and is suitable for copper pipe welding with high quality requirements.

[0051] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
