Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling for brazing inner linings, specifically to an auxiliary tooling for brazing inner linings of a water-cooled nozzle shell. Background Technology

[0002] Brazing of the water-cooled nozzle shell and liner is a welding process used to connect the shell and liner of the water-cooled nozzle, and is mainly used to manufacture key components in water-cooling systems.

[0003] Common brazing auxiliary fixtures for inner liners typically use clamps to fix the water-cooled nozzle and inner liner, ensuring that their relative positions remain unchanged during the brazing process and preventing displacement or deformation. Locating pins are used to determine the correct installation position of the nozzle and inner liner, ensuring the accuracy and consistency of the welding.

[0004] However, during the welding process of the water-cooled nozzle, the nozzle needs to remain stationary. As the adhesive medium between stainless steel and chromium zirconium copper, the nozzle will inevitably shake during the high-temperature and cooling process, making it difficult to ensure sufficient adhesion between the stainless steel and chromium zirconium copper, resulting in weak solder joints on the water-cooled nozzle. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an auxiliary tooling for brazing the inner lining of a water-cooled nozzle shell, thereby solving the problem mentioned in the background art that the water-cooled nozzle will inevitably shake during the high-temperature and cooling process, making it difficult to ensure sufficient adhesion between the stainless steel and chromium zirconium copper, resulting in weak soldering of the water-cooled nozzle.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary tooling for brazing the inner lining of a water-cooled spray pipe shell, comprising:

[0009] A first tooling plate, and a second tooling plate is provided on both the upper and lower surfaces of the first tooling plate. The first tooling plate is located on both sides of the second tooling plate, and a limiting sleeve is provided on the inner side of both the first tooling plate and the second tooling plate.

[0010] Brazing clamps are installed on both sides of the surface of the first tooling plate and the second tooling plate. The brazing clamps are composed of two L-shaped plates, and bolts are screwed into the connection points of the brazing clamps.

[0011] The third tooling plate is disposed on both sides of the surface of the first tooling plate. The third tooling plate is located between the first tooling plate and the second tooling plate. Adjusting rods are screwed onto the surface of the third tooling plate, and positioning plates are installed on the inner ends of the adjusting rods through bearings.

[0012] Preferably, a first threaded rod is screwed onto both sides of the surface of the first tooling plate. The first threaded rod passes through the first tooling plate and is screwed onto the surface of the third tooling plate. The first threaded rod can connect the two first tooling plates and also connect to the third tooling plate, thereby enabling the compression of both sides of the second tooling plate.

[0013] Preferably, each of the four corners of the second tooling plate is screwed with a second threaded rod, which passes through the second tooling plate and is screwed onto the surface of the third tooling plate. The second tooling plates can be connected through the second threaded rods, and the second tooling plate can also be connected to the third tooling plate.

[0014] Preferably, all the limiting sleeves are arc-shaped and are assembled into a tubular shape, so as to fit tightly against the surface of the water-cooled nozzle shell.

[0015] Preferably, mounting blocks are installed on both sides of the surface of the limiting sleeve, and positioning rods are screwed onto the surface of each mounting block. The positioning rods are screwed onto the surfaces of the first tooling plate and the second tooling plate, respectively, and can be screwed onto the surface of the mounting blocks, thereby enabling the installation of the limiting sleeve.

[0016] Preferably, limit rods are installed on both sides of the surface of the positioning plate, and the limit rods penetrate the surface of the third tooling plate, so that the positioning plate can move linearly.

[0017] Beneficial effects

[0018] Compared with the prior art, this utility model provides an auxiliary tooling for brazing the inner lining of a water-cooled nozzle shell, which has the following beneficial effects:

[0019] The brazing auxiliary fixture for the inner lining of the water-cooled nozzle shell works by placing the water-cooled nozzle shell between two fixture plates, placing the first fixture plate on both sides of the second fixture plate, and tightening the brazing clamps by rotating the bolts. This compresses the first and second fixture plates, which in turn compresses the limiting sleeve against the water-cooled nozzle shell. Rotating the adjusting rod moves the positioning plate to position both ends of the water-cooled nozzle shell, thus preventing the water-cooled nozzle shell from shaking during high-temperature and cooling processes. This ensures full adhesion between the stainless steel and chromium zirconium copper, and improves the strength of the solder joints on the water-cooled nozzle. Attached Figure Description

Figure 1 It includes a first tooling plate 1, and a second tooling plate 2 is provided on both the upper and lower surfaces of the first tooling plate 1. The first tooling plate 1 is located on both sides of the second tooling plate 2. Please refer to [link / reference]. Figure 2 and Figure 3 Both the first tooling plate 1 and the second tooling plate 2 are provided with limiting sleeves 3 on their inner sides;

[0028] Please see Figure 1 Brazed clamps 4 are installed on both sides of the surfaces of the first tooling plate 1 and the second tooling plate 2. Brazed clamps 4 are composed of two L-shaped plates. Please refer to [link / reference]. Figure 5 Bolts 5 are screwed into all the joints of the brazed clamps 4;

[0029] Please see Figure 1 The third tooling plate 6 is disposed on both sides of the surface of the first tooling plate 1, and is located between the first tooling plate 1 and the second tooling plate 2. Please refer to [link / reference]. Figure 4 The surface of the third tooling plate 6 is screwed with an adjusting rod 7, and the inner end of the adjusting rod 7 is equipped with a positioning plate 8 through a bearing.

[0030] The water-cooled nozzle shell is placed between the second tooling plates 2, and the first tooling plate 1 is placed on both sides of the second tooling plate 2. The rotating bolt 5 tightens the brazing clamp 4, thereby squeezing the first tooling plate 1 and the second tooling plate 2, which in turn drives the limiting sleeve 3 to squeeze the water-cooled nozzle shell. The rotating adjusting rod 7 drives the positioning plate 8 to move and position the two ends of the water-cooled nozzle shell, thereby preventing the water-cooled nozzle shell from shaking during the high temperature and cooling process, ensuring the full adhesion of stainless steel and chromium zirconium copper, and improving the firmness of the water-cooled nozzle soldering.

[0031] Please see Figure 2 Both sides of the surface of the first tooling plate 1 are screwed with first threaded rods 9. The first threaded rods 9 penetrate the first tooling plate 1 and are screwed onto the surface of the third tooling plate 6. The two first tooling plates 1 can be connected by the first threaded rods 9, and they can also be connected to the third tooling plate 6, thereby enabling the compression of both sides of the second tooling plate 2.

[0032] Please see Figure 3 Each of the four corners of the surface of the second tooling plate 2 is screwed with a second threaded rod 10. The second threaded rod 10 passes through the second tooling plate 2 and is screwed onto the surface of the third tooling plate 6. The second tooling plate 2 can be connected through the second threaded rod 10, and the second tooling plate 2 can also be connected to the third tooling plate 6.

[0033] Please see Figure 3 All the limiting sleeves 3 are arc-shaped and are assembled into a tube, so that they can fit tightly against the surface of the water-cooled spray pipe shell.

[0034] Please see Figure 2 Mounting blocks 11 are installed on both sides of the surface of the limiting sleeve 3. Positioning rods 12 are screwed onto the surface of each mounting block 11. The positioning rods 12 are screwed onto the surfaces of the first tooling plate 1 and the second tooling plate 2 respectively, and can be screwed onto the surface of the mounting block 11, thereby enabling the installation of the limiting sleeve 3.

[0035] Please see Figure 4 Limiting rods 13 are installed on both sides of the surface of the positioning plate 8. The limiting rods 13 penetrate the surface of the third tooling plate 6, enabling the positioning plate 8 to move linearly.

[0036] In operation, this solution works as follows: First, the water-cooled spray pipe shell is placed between the second tooling plates 2. The first tooling plate 1 is placed on both sides of the second tooling plate 2. The two first tooling plates 1 are connected by the first threaded rod 9, and can also be connected to the third tooling plate 6, thereby pressing the two sides of the second tooling plate 2. Then, the second tooling plate 2 is connected by the second threaded rod 10, and can also be connected to the third tooling plate 6. Finally, the brazing clamp 4 is tightened by rotating the bolt 5, thereby pressing the first tooling plate 1 and the second tooling plate 2, which in turn drives the limiting sleeve 3 to press the water-cooled spray pipe shell. Rotating the adjusting rod 7 drives the positioning plate 8 to move and position the two ends of the water-cooled spray pipe shell, thereby preventing the water-cooled spray pipe shell from shaking during the high temperature and cooling process, ensuring full adhesion between the stainless steel and chromium zirconium copper, and improving the firmness of the water-cooled spray pipe soldering.
