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

[0016] Please see Figure 1-2This utility model provides a technical solution: an electron beam welding fixture for sintered metal mesh, including a base 1. Two parallel rodless cylinders 8 are fixedly mounted on the upper surface of the base 1. Two pressing moving parts 9 are fixed between the upper surfaces of the sliding seats of the two rodless cylinders 8. A welding shell 11 is fixed between the two pressing moving parts 9. A welding mechanism 10 is fixed in the middle of the inner top surface of the welding shell 11. Two sealing grooves 2 are provided on the upper surface of the base 1. The lower end of the welding shell 11 can be pressed and sealed with the inside of the sealing grooves 2. A set of rails 3 is provided in the middle of each of the two sealing grooves 2. Two parallel rails 3 form a set. Each set of rails 3 is provided with a sliding seat 5 that is slidably connected. A rack 4 is provided on one side of the upper surface of the sliding seat 5. A gear drive component 7 that can mesh with the rack 4 is provided on the side. Two workpiece support seats 12 are provided on the upper surface of each sliding seat 5. The upper surface of the workpiece support seat 12 has an arc-shaped structure. A workpiece clamping assembly 6 is provided on the upper surface of each sliding seat 5. The downward moving component 9 includes a U-shaped frame 91 fixed between two rodless cylinders 8. A hydraulic telescopic cylinder 92 is fixed at the center of the upper surface of each U-shaped frame 91. The extension and retraction of the hydraulic telescopic cylinder 92 can drive the welding shell 11 to move downwards, so that the lower end of the welding shell 11 is sealed and connected with one of the sealing grooves 2. The gear drive component 7 includes a motor 71 fixed on one side of the welding shell 11. The output shaft end of the motor 71 extends into the interior of the welding shell 11 and is fixed with a gear 72. When the welding shell 11 is sealed with one of the sealing grooves 2... When a sealing groove 2 is sealed, gear 72 meshes with the corresponding rack 4. The rotation of motor 71 drives gear 72 to rotate, which in turn moves rack 4, which in turn moves sliding seat 5, which in turn moves the workpiece. This allows the cylindrical metal sintered mesh to move during welding. The workpiece clamping assembly 6 includes a second track 64 fixed to the upper surface of sliding seat 5. Two slidably connected workpiece clamping parts 61 are mounted on track 64, with the two clamping parts 61 corresponding to each other. A support 62 is mounted on the upper surface of sliding seat 5, and a rotatably connected stud 63 is mounted on support 62. The threads at the front and rear ends of stud 63 are in opposite directions, and the two ends of stud 63 are respectively connected by threads. The mechanism connects to the workpiece clamping components 61. The upper ends of opposite sides of the two workpiece clamping components 61 are arc-shaped. One end of the stud 63 has a rotating head. An external tool drives the rotating head to rotate, which in turn rotates the stud 63, causing the workpiece clamping components 61 to move. This allows adjustment of the distance between the two workpiece clamping components 61, and the workpiece clamping components 61 can clamp and fix the workpiece. A blocking block 13 is fixed between both ends of each set of tracks 3. These two blocking blocks 13 limit the sliding position of the sliding seat 5 at its left and right ends.This electron beam welding fixture for sintered metal mesh has a simple structure. Two workpiece positioning seats can work alternately, resulting in faster workpiece processing speeds and allowing for workpiece movement during welding within a vacuum welding chamber.

[0017] In use: The cylindrical workpiece is supported by the workpiece support seat 12. An external tool drives the rotating head to rotate, which in turn drives the stud 63 to rotate. The stud 63 then moves the workpiece clamping member 61, allowing adjustment of the distance between the two clamping members 61. The workpiece is clamped and fixed by the clamping member 61. The rodless cylinder 8 drives the downward moving member 9 and the welding shell 11 to move. The hydraulic telescopic cylinder 92 extends and retracts, causing the welding shell 11 to move downward, sealing the lower end of the welding shell 11 with one of the sealing grooves 2. When the welding shell 11 is sealed with one of the sealing grooves 2, the gear 72 meshes with the corresponding rack 4. The motor 71 rotates, which drives the gear 72 to rotate, which in turn drives the rack 4 to move. The rack 4 then drives the sliding seat 5 to move, which in turn moves the workpiece. The welding mechanism 10 then welds the workpiece, thus allowing the cylindrical metal sintered mesh to move during welding.
