Description

Technical Field

[0001] This utility model relates to the field of duplex stainless steel processing technology, specifically a positioning fixture for welding duplex stainless steel. Background Technology

[0002] Duplex stainless steel is a special type of stainless steel. The "duplex" in its name comes from its unique microstructure. This dual-phase structure endows it with high strength and excellent corrosion resistance, making it particularly suitable for harsh industrial environments. During the welding process of duplex stainless steel, in order to ensure the welding quality, appropriate clamps are used to fix and hold the duplex stainless steel. In the existing technology, the positioning clamps for duplex stainless steel are not very flexible, especially in the process of adjusting the direction and angle, which is quite inconvenient. Therefore, in order to solve this problem, this paper was developed to design a positioning clamp for welding duplex stainless steel. Utility Model Content

[0003] The purpose of this invention is to provide a positioning fixture for welding duplex stainless steel to solve the problem of direction and angle adjustment mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a positioning fixture for welding duplex stainless steel, comprising a base, a guide groove at the middle position of the top of the base, a movable gear inside the guide groove, a connecting rod at the top of the movable gear, the top of the connecting rod penetrating the top of the guide groove and connecting to a second positioning platform, a driven circular gear on the outer side of the second positioning platform, a rotating rod at the center of the top of the base via a bearing, a driving gear on the outer side of the rotating rod, a first positioning platform welded to the top of the rotating rod, and mounting grooves at the middle positions of the tops of both the first and second positioning platforms, a bidirectional threaded rod at one end inside the mounting groove via a bearing, the other end of the bidirectional threaded rod penetrating the other end of the mounting groove and connecting to a rotating handle, two threaded blocks sleeved on the outer side of the bidirectional threaded rod, a driving circular gear mounted on the outer side of the first positioning platform, and two clamping plates at the top of both the first and second positioning platforms, an electric telescopic rod at the top of the base, a mounting plate at one end of the electric telescopic rod via bolts, and a toothed plate mounted on one side of the mounting plate.

[0005] Preferably, the toothed plate and the drive gear are located at the same height, and the toothed plate and the drive gear mesh with each other.

[0006] Preferably, the driving circular gear and the driven circular gear are located at the same height and mesh with each other.

[0007] Preferably, the guide groove is annular in shape, and the inner wall of the guide groove is provided with a serrated groove that matches the outer side of the movable gear.

[0008] Preferably, the clamping plate is positioned directly above the threaded block, and the top end of the threaded block penetrates the top end of the mounting groove and connects to the bottom end of the clamping plate.

[0009] Preferably, the threaded block is square in shape, and the bottom end of the threaded block is in contact with the bottom end of the mounting groove.

[0010] Preferably, the clamping plates are symmetrical about the vertical central axis of the bidirectional threaded rod with respect to the threaded blocks, and the length of the bidirectional threaded rod is slightly smaller than the diameter of the first positioning table, while the diameters of the first positioning table and the second positioning table are the same.

[0011] Compared with related technologies, the positioning fixture for welding duplex stainless steel provided by this utility model has the following advantages:

[0012] This utility model provides a driven circular gear and a mounting plate. By utilizing the extension and retraction of the threaded block to drive the mounting plate to move horizontally, the gear plate can push the driving gear to rotate, which in turn drives the driven circular gear to rotate. Ultimately, this causes the movable gear to roll along the inside of the guide groove, achieving the position adjustment effect between the first positioning platform and the second positioning platform. This enables the device to achieve the direction and angle adjustment function, improving the welding efficiency and quality of duplex stainless steel. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Example 1: Please refer to Figure 1-4 A positioning fixture for welding duplex stainless steel includes a base 1. A guide groove 2 is formed at the middle of the top of the base 1, and a movable gear 15 is arranged inside the guide groove 2. A connecting rod 16 is installed at the top of the movable gear 15, and the top of the connecting rod 16 passes through the top of the guide groove 2 and is connected to a second positioning platform 7. A driven circular gear 6 is installed on the outside of the second positioning platform 7. A rotating rod 11 is installed at the center of the top of the base 1 via a bearing, and a driving gear 14 is installed on the outside of the rotating rod 11. A first positioning platform 4 is welded to the top of the rotating rod 11, and the first positioning platform 4 and the second positioning platform 7 are connected to the first positioning platform 7. A mounting groove 5 is provided at the middle position of the top of the positioning platform 7. A double-threaded rod 10 is installed at one end of the mounting groove 5 through a bearing, and the other end of the double-threaded rod 10 passes through the other end of the mounting groove 5 and is connected to a rotating handle 9. Two threaded blocks 17 are sleeved on the outside of the double-threaded rod 10. An active circular gear 3 is installed on the outside of the first positioning platform 4. Two clamping plates 8 are provided at the top of the first positioning platform 4 and the second positioning platform 7. An electric telescopic rod 18 is installed at the top of the base 1, and a mounting plate 13 is installed at one end of the electric telescopic rod 18 through bolts. A toothed plate 12 is installed on one side of the mounting plate 13.

[0020] The toothed plate 12 and the driving gear 14 are at the same height and mesh with each other;

[0021] The driving circular gear 3 and the driven circular gear 6 are located at the same height and are meshed.

[0022] The guide groove 2 is annular in shape, and the inner wall of the guide groove 2 is provided with a serrated groove that matches the outer side of the movable gear 15.

[0023] The clamping plate 8 is positioned directly above the threaded block 17, and the top of the threaded block 17 penetrates the top of the mounting groove 5 and connects to the bottom of the clamping plate 8.

[0024] The threaded block 17 is square in shape, and the bottom end of the threaded block 17 is in contact with the bottom end of the mounting groove 5.

[0025] The clamping plates 8 are symmetrical about the vertical central axis of the double-threaded rod 10 about the threaded block 17, and the length of the double-threaded rod 10 is slightly smaller than the diameter of the first positioning table 4, while the diameters of the first positioning table 4 and the second positioning table 7 are the same.

[0026] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in the operation of this device, the first positioning platform 4 and the second positioning platform 7 are provided. Two duplex stainless steel pieces to be welded are placed on the first positioning platform 4 and the second positioning platform 7 respectively. Then, using the clamping plate 8, the operator rotates the rotating handle 9. Rotating the handle 9 drives the bidirectional threaded rod 10 to rotate. The rotation of the bidirectional threaded rod 10 and the constraint at the bottom of the mounting groove 5 cause the two threaded blocks 17 to move horizontally in opposite directions along the bidirectional threaded rod 10. This drives the clamping plate 8 to move synchronously, allowing for flexible adjustment of the distance between the two clamping plates 8 to achieve a stable positioning and clamping effect on the duplex stainless steel, thus ensuring the quality of subsequent welding. Furthermore, to improve the flexibility of the device and increase the welding efficiency and quality of duplex stainless steel, the device is equipped with a drive gear 14. The extension and retraction of the electric telescopic rod 18 drives the mounting plate 13 to move horizontally. During the movement of the mounting plate 13, the toothed plate 12 is driven to move... Synchronous movement occurs because the toothed plate 12 and the driving gear 14 mesh, causing the toothed plate 12 to move and the driving gear 14 to rotate. This rotation of the driving gear 14 then causes the rotating rod 11 to rotate, which in turn causes the first positioning platform 4 and the driving circular gear 3 to rotate. The meshing of the driving circular gear 3 and the driven circular gear 6 causes the driven circular gear 6 to rotate, which in turn causes the second positioning platform 7 to rotate. The rotation of the second positioning platform 7 then causes the movable gear 15 to rotate via the connecting rod 16. Since the movable gear 15 meshes with the inner wall of the guide groove 2, it can roll along the inside of the guide groove 2 during rotation. This allows the second positioning platform 7 to revolve around the outer side of the first positioning platform 4 while rotating on its own axis, thus flexibly adjusting the relative positions of the first and second positioning platforms 4 to achieve directional angle adjustment and improve the welding efficiency and quality of duplex stainless steel.
