[0002] Friction stir welding is a solid-state joining technology based on friction welding technology. It is a high-efficiency, energy-saving, and environmentally friendly high-end new joining technology. Its principle is the same as that of conventional friction welding, using frictional heat and plastic deformation heat as welding heat sources.

[0003] However, the existing friction stir welding worktables are usually only suitable for one type of workpiece shape. The worktable is fixed on the welding station base. When friction stir welding workpieces of another shape, a new device is required, which is not very applicable. Utility Model Content

[0004] The purpose of this utility model is to provide a detachable worktable for friction stir welding, so as to solve the problem mentioned in the background art that the existing worktable can usually only be used for workpieces of one shape, and the worktable is fixed on the welding station base, resulting in low applicability.

[0005] This utility model can be achieved through the following technical solutions:

[0006] A detachable workbench for friction stir welding includes a base. A first placement seat and a second placement seat are slidably disposed on the top surface of the base. The upper surfaces of both placement seats have a bearing cavity for loading workpieces, and the bottom surfaces of both placement seats have a limiting seat. The inner wall of the limiting seat has an installation groove. The lower surface of the base has a pushing assembly for simultaneously moving placement seats one and two. The upper surface of the base has two limiting grooves. Two fixing plates are fixedly installed on the lower surface of the base outside the limiting grooves. A limiting rod is perforated through the surface of one fixing plate, and a socket for insertion into the end of the limiting rod is installed on the inner wall of the other fixing plate. A fastening nut is threaded onto one end of the limiting rod, and the limiting rod is slidably disposed with the limiting seat.

[0007] A further technical improvement of this utility model is that: the pushing component includes a rotary cylinder, the driving end of the rotary cylinder is equipped with a deflection seat, both ends of the deflection seat are rotatably connected to a transmission rod, the end of each transmission rod extends into the mounting groove and is hinged to a corresponding limiting seat, and the lower surface of the limiting seat is equipped with a hinge joint that passes through the mounting end of the transmission rod.

[0008] A further technical improvement of this utility model is that a threaded rod is threadedly installed on the end face of the placement seat, and the end of the threaded rod is rotatably connected to a sealing plate that contacts the end of the workpiece.

[0009] A further technical improvement of this utility model is that: the bearing cavity is a rectangular or arc-shaped structure, and the bottom of the inner wall surface of the bearing cavity is provided with a T-shaped sliding cavity, and the end of the inner wall surface of the bearing cavity is provided with an installation groove for the sealing plate to enter.

[0010] A further technical improvement of this utility model is that: the sealing plate includes a pressure plate one and a pressure plate two, one side of the pressure plate one is slidably fitted with a T-shaped sliding cavity in the bearing cavity, the other side of the pressure plate one is inserted into the pressure plate two, and the side of the pressure plate two slides with a T-shaped sliding cavity in another bearing cavity.

[0011] A further technical improvement of this utility model is that: both ends of the first pressure plate and the second pressure plate are provided with insert blocks, and the end surfaces of the first pressure plate and the second pressure plate are provided with slots for inserting the insert blocks.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Placement seat one and placement seat two can be replaced according to the shape of the workpiece to be welded. Initially, there is a gap between placement seat one and placement seat two. After the workpiece is placed into the bearing cavity, placement seat one and placement seat two move closer to each other under the push of the push component. At this time, placement seat one and placement seat two drive the limiting seat to slide in the corresponding limiting groove. The fitted placement seat one and placement seat two fasten the side of the workpiece to ensure the stability of the friction stir welding. When disassembling and replacing placement seat one and placement seat two, first remove the fastening nut, pull the limiting rod to one side, and the end of the limiting rod leaves the socket and is pulled out from the limiting seat and the fixing plate, which facilitates the removal of the limiting seat, thereby replacing placement seat one and placement seat two of different shapes and sizes, improving the applicability of friction stir welding.

[0014] 2. Initially, pressure plate one and pressure plate two are close to the end face of the bearing cavity, and pressure plate one and pressure plate two are kept on the same horizontal plane. When the workpiece approaches the placement seat one and placement seat two, the inserts on pressure plate one and pressure plate two respectively enter the slots to realize the insertion of the sealing plate. Then, the threaded rod is rotated, and the threaded rod pushes the sealing plate to slide along the T-shaped sliding cavity on the inner wall of the bearing cavity, pressing and limiting the end face of the workpiece, thus improving the welding quality of the workpiece.

Detailed Implementation

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] Please see Figures 1-5As shown, this utility model provides a detachable workbench for friction stir welding, including a base 1. A first placement seat 2 and a second placement seat 3 are slidably disposed on the top surface of the base 1. The upper surfaces of both placement seats 2 and 3 are provided with a bearing cavity 7 for loading workpieces, and the bottom surfaces of both placement seats 2 and 3 are provided with a limiting seat 11. The inner wall of the limiting seat 11 is provided with an installation groove 16. The lower surface of the base 1 is provided with a pushing assembly for simultaneously moving placement seats 2 and 3. The upper surface of the base 1 is provided with two limiting grooves 4. Two fixing plates 12 are fixedly installed on the lower surface of the base 1 outside the limiting grooves 4. A limiting rod 13 is perforated through the surface of one fixing plate 12, and a socket 18 for insertion into the end of the limiting rod 13 is installed on the inner wall of the other fixing plate 12. A fastening nut 19 is threaded onto one end of the limiting rod 13. The limiting seat 11 is slidably set, and the placement seat 1 2 and placement seat 2 3 can be replaced according to the shape of the workpiece to be welded. Initially, there is a gap between placement seat 1 2 and placement seat 2 3. After the workpiece is placed into the bearing cavity 7, placement seat 1 2 and placement seat 2 3 move closer to each other under the push of the pushing component. At this time, placement seat 1 2 and placement seat 2 3 drive the limiting seat 11 to slide in the corresponding limiting groove 4. The fitted placement seat 1 2 and placement seat 2 3 fasten the side of the workpiece to ensure the stability of the friction stir welding. When disassembling and replacing placement seat 1 2 and placement seat 2 3, first remove the fastening nut 19, pull the limiting rod 13 to one side, and the end of the limiting rod 13 leaves the socket 18 and is pulled out from the limiting seat 11 and the fixing plate 12, which facilitates the removal of the limiting seat 11, thereby replacing placement seat 1 2 and placement seat 2 3 with different shapes and sizes, improving the applicability of friction stir welding.

[0024] See Figure 5 As shown, the pushing assembly includes a rotary cylinder 17. A deflector seat 14 is mounted on the drive end of the rotary cylinder 17. Both ends of the deflector seat 14 are rotatably connected to transmission rods 15. The end of each transmission rod 15 extends into the mounting groove 16 and is hinged to the corresponding limiting seat 11. A hinge joint is mounted on the lower surface of the limiting seat 11, passing through the mounting end of the transmission rod 15. The rotary cylinder 17 drives the deflector seat 14 to rotate, causing the two transmission rods 15 to pull the corresponding limiting seat 11 to slide on the limiting rod 13. When the limiting seat 11 moves, the corresponding placement seat 1 2 and placement seat 2 3 move together. When friction stir welding is performed on workpieces of different shapes, the rotary cylinder 17 does not work. After the limiting rod 13 is removed, the hinge joint is also removed. At this time, the transmission rod 15 is disengaged from the mounting groove 16 and loses its connection restriction. By lifting the placement seat 1 2 and placement seat 2 3 upwards, the limiting seat 11 moves out of the limiting groove 4.

[0025] See Figure 2As shown, a threaded rod 8 is threadedly installed on the end face of the placement seat 2, and a sealing plate that contacts the end of the workpiece is rotatably connected to the end of the threaded rod 8; the bearing cavity 7 is a rectangular or arc-shaped structure that is adapted to the shape of the workpiece to improve its application range. The bottom of the inner wall of the bearing cavity 7 is provided with a T-shaped sliding cavity, and the end of the inner wall of the bearing cavity 7 is provided with a notch for the sealing plate to enter. The sealing plate enters the bearing cavity 7 through the notch and slides along the T-shaped sliding cavity.

[0026] See Figure 2 and Figure 3 As shown, the sealing plate includes pressure plate 5 and pressure plate 6. One side of pressure plate 5 slides against the T-shaped cavity in the bearing cavity 7, and the other side of pressure plate 5 is inserted into pressure plate 6. The side of pressure plate 6 slides against another T-shaped cavity in the bearing cavity 7. Both pressure plate 5 and pressure plate 6 have inserts 10 at their ends, and the end surfaces of pressure plate 5 and pressure plate 6 have slots 9 for inserting the inserts 10. Initially, pressure plate 5 and pressure plate 6 are close to the end face of the bearing cavity 7, and pressure plate 5 and pressure plate 6 are kept at the same horizontal plane. When the workpiece approaches the placement seat 2 and placement seat 3, the inserts 10 on pressure plate 5 and pressure plate 26 respectively enter the slots 9 to achieve the insertion of the sealing plate. Then, the threaded rod 8 is rotated, and the threaded rod 8 pushes the sealing plate to slide along the inner wall of the bearing cavity 7 to limit the end face of the workpiece and improve the welding quality of the workpiece.

[0027] In use, the placement seat 1 2 and placement seat 2 3 can be replaced according to the shape of the workpiece to be welded. Initially, there is a gap between placement seat 1 2 and placement seat 2 3. After the workpiece is placed into the bearing cavity 7, placement seat 1 2 and placement seat 2 3 move closer to each other under the push of the push component. At this time, placement seat 1 2 and placement seat 2 3 drive the limiting seat 11 to slide in the corresponding limiting groove 4. The close-fitting placement seat 1 2 and placement seat 2 3 fasten the side of the workpiece to ensure the stability of the friction stir welding. When disassembling and replacing placement seat 1 2 and placement seat 2 3, first remove the fastening nut 19, pull the limiting rod 13 to one side. The end of the limiting rod 13 leaves the socket 18 and is pulled out from the limiting seat 11 and the fixing plate 12, which facilitates the removal of the limiting seat 11, thereby replacing placement seat 1 2 and placement seat 2 3 with different shapes and sizes, improving the applicability of friction stir welding.

[0028] Initially, pressure plate 5 and pressure plate 6 are close to the end face of the bearing cavity 7, and pressure plate 5 and pressure plate 6 are kept on the same horizontal plane. When the workpiece approaches the placement seat 2 and placement seat 3, the insert blocks 10 on pressure plate 5 and pressure plate 6 respectively enter the slot 9 to realize the insertion of the sealing plate. Then, the threaded rod 8 is rotated, and the threaded rod 8 pushes the sealing plate to slide along the T-shaped sliding cavity on the inner wall of the bearing cavity 7 to press and limit the end face of the workpiece, thereby improving the welding quality of the workpiece.
