Description

Technical Field

[0001] This utility model relates to the field of welding tooling equipment, and in particular to a multi-angle welding test platform. Background Technology

[0002] The corrugated pipe of the hydropower station unit consists of four layers, each layer made of 1.5 mm thick stainless steel sheet, with the inner sleeve wall made of 6 mm thick high-strength steel plate. Before actual welding of the corrugated pipe, extensive experiments are required to verify the accuracy of the welding process. Welding the corrugated pipe involves different positions, including flat welding, vertical welding, and overhead welding. The welding process for each position must be verified before it can be applied to actual corrugated pipe welding. Therefore, a multi-functional welding test platform capable of simulating welding in different positions is needed, simulating flat welding, vertical welding, and overhead welding. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a multi-angle welding test platform for fixing the welded workpiece, so as to facilitate the simulation of different welding angles during welding process verification.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a multi-angle welding test platform, including a mounting plate, a vertical plate on the mounting plate, an upper plate on the top of the vertical plate, multiple sets of mounting holes on both the upper plate and the vertical plate, and several pressure blocks on the upper side of the upper plate and one side of the vertical plate for pressing the welded workpiece, the pressure blocks being connected to the mounting holes by bolts.

[0005] In a preferred embodiment, one end of the upper plate is provided with an extension plate, the extension plate is provided with multiple sets of mounting holes, and the bottom of the extension plate is also provided with several pressure blocks for pressing the welded workpiece.

[0006] In a preferred embodiment, at least two sets of vertical plates are provided, and heat dissipation space is formed between adjacent vertical plates, upper plates, and mounting plates.

[0007] In a preferred embodiment, the surface roughness of the upper surface of the upper plate and the lower surface of the extension plate is 0.8 to 1.6.

[0008] In a preferred embodiment, the pressure block has a strip-shaped structure and a strip-shaped hole for bolts to pass through.

[0009] The multi-angle welding test platform provided by this utility model has the following beneficial effects:

[0010] 1. The upper plate is the working plate. The front side can be used for studying flat welding processes, while the workpiece is pressed against the vertical plate by pressure blocks for studying vertical welding processes. This allows for welding process experiments from multiple angles.

[0011] 2. The upright plate is a support plate used to connect the upper plate and the mounting plate, and at the same time, it serves to isolate the upper plate and the mounting plate, which can better release the heat generated during the welding process.

[0012] 3. The large space created between the upright plate, mounting plate, and top plate facilitates heat dissipation during welding. It also allows for the placement of materials with good heat dissipation for welding operations requiring better cooling or simulating cold environments. Furthermore, it can accommodate heating devices for situations requiring heating of the welding materials or simulating high-temperature environments. Attached Figure Description

[0018] Example 1:

[0019] like Figures 1-3 As shown, a multi-angle welding test platform includes a mounting plate 1, which serves as the foundation of the entire platform and can be easily installed on robot workbenches, welding platforms, etc. The mounting plate 1 is made of 316L stainless steel, which ensures both strength and heat dissipation during the welding process, while also allowing it to operate in environments with different temperatures and humidity levels without rusting.

[0020] The mounting plate 1 is provided with a vertical plate 2, and the top of the vertical plate 2 is provided with an upper plate 3. The vertical plate 2 is a support plate used to connect the upper plate 3 and the mounting plate 1, and at the same time, it serves to isolate the upper plate 6 and the mounting plate 1, so as to better release the heat generated during the welding process. The upper plate 3 is connected to the vertical plate 2 by bolts.

[0021] The upright plate 2 is also made of 316L stainless steel and is connected to the mounting plate 1 by bolts.

[0022] Both the upper plate 3 and the vertical plate 2 are provided with multiple sets of mounting holes 4, which are arranged alternately to install various types of pressure blocks for welding process research. Several pressure blocks 5 are provided on the upper side of the upper plate 3 and one side of the vertical plate 2 for pressing the welded workpiece. The pressure blocks 5 are connected to the mounting holes 4 by bolts.

[0023] The upper plate 3 is the working plate, made of 316L stainless steel, and its front side can be used for research on flat welding processes. The workpiece is pressed onto the vertical plate 2 by the pressure block 5 for research on vertical welding processes.

[0024] Preferably, one end of the upper plate 3 is provided with an extension plate 6, the extension plate 6 is provided with multiple sets of mounting holes 4, and the bottom of the extension plate 6 is also provided with several pressure blocks 5 for pressing the welded workpiece.

[0025] The extension plate 6 can be an integral plate of the upper plate 3, which is convenient for processing. The extension plate 6 extends to the outside of the vertical plate 2, which makes it convenient to install and weld workpieces at the bottom of the extension plate 6 through the pressure block 5.

[0026] During processing, the surface roughness of the upper plane of the upper plate 3 and the lower plane of the extension plate 6 is 0.8~1.6, which fully ensures the flatness of the upper plane of the upper plate 3 and the lower plane of the extension plate 6, and can ensure that the welded workpiece is stably and reliably attached to the mounting surface during welding experiments.

[0027] Preferably, the pressure block 5 has a strip-shaped structure and a strip-shaped hole 501 for the bolt to pass through. By setting the hole on the 5 that mates with the bolt as a strip-shaped hole 501, the position of the pressure block 5 can be flexibly adjusted to mate with the mounting hole 4.

[0028] Example 2:

[0029] Unlike Embodiment 1, the upright plate 2 is provided in at least two sets, forming a heat dissipation space 7 between adjacent upright plates 2, upper plate 3, and mounting plate 1. The relatively large space formed between the upright plates 2, mounting plate 1, and upper plate 3 allows for the placement of materials with good heat dissipation properties, such as liquid nitrogen, for welding operations requiring better heat dissipation or simulating welding in cold environments. Simultaneously, a heating device can be placed there for situations requiring heating of the welding materials to complete the welding or for simulating welding operations in high-temperature environments.

[0030] Example 3:

[0031] The usage process of this platform is explained using the flat welding process verification as an example:

[0032] Prepare a thin stainless steel sheet as the welding workpiece and place it on the upper plate 3. Adjust the position of the workpiece to ensure it is within the appropriate flat welding area. Using the pressure block 5 on the upper side of the upper plate 3, pass the bolt through the slotted hole 501 of the pressure block 5 and screw it into the mounting hole 4 of the upper plate 3. Tighten the bolt to ensure the pressure block 5 firmly presses against the upper surface of the welding workpiece, preventing displacement during the flat welding process. Start the welding equipment and perform the welding operation according to the predetermined flat welding process parameters. During the welding process, observe the welding effect, such as the flatness of the weld and the penetration depth. After welding, perform visual inspection and non-destructive testing on the weld joint and record the results. By repeating the above operation multiple times using different welding parameters and materials, verify the feasibility and stability of the flat welding process on this multi-angle welding test platform.

[0033] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The embodiments and features described in this application can be arbitrarily combined without conflict. The protection scope of this utility model should be defined as the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
