[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] Example 1

[0029] Please see Figures 1-5 A welding fixture for manufacturing industrial robots includes a welding fixture table 1. Two symmetrical clamping seats 2 are provided on the upper part of the welding fixture table 1. Several first sliding blocks 3 are slidably connected to the sides of the clamping seats 2. First sliding grooves 4, adapted to the first sliding blocks 3, are opened through the opposite sides of the clamping seats 2. A threaded rod 5 is provided on each of the first sliding blocks 3. The first sliding blocks 3 can be adjusted and fixed along their length on the clamping seats 2. The threaded rod 5 can be adjusted and fixed in a horizontal position on the first sliding blocks 3. A first threaded post 6 is fixedly installed on the upper part of the first sliding block 3. A moving groove 7, adapted to the first threaded post 6, is opened on the upper part of the clamping seats 2. The threaded post 6 has a first limiting nut 8 for limiting and fixing the first sliding block 3. The first sliding block 3 has a second sliding block 9 inside. The first sliding block 3 has a second sliding groove 10 on the opposite side that is adapted to the second sliding block 9 and is vertical. The second threaded post 11 adapted to the second sliding groove 10 is fixedly installed on one side of the second sliding block 9. The second threaded post 11 has a second limiting nut 12 for limiting and fixing the second sliding block 9. The threaded rod 5 passes through the second threaded post 11 and the second sliding block 9 and is threadedly connected to the second sliding block 9. The threaded rod 5 has a third limiting nut 13 for limiting and fixing the threaded rod 5.

[0030] In this specific embodiment, when welding the arms of an industrial robot is required, the sheet metal consisting of two arms is placed on the upper part of the welding fixture 1 and aligned. The horizontal position of the first sliding block 3 on the clamping seat 2 is adjusted according to the position where the welding arms need to be clamped. The first sliding block 3 slides within the first sliding groove 4. When the first sliding block 3 moves, the first threaded post 6 moves within the moving groove 7. After the position of the first sliding block 3 is adjusted to a suitable position, the first limiting nut 8 is tightened to limit and fix the position of the first sliding block 3. By rotating the abutting threaded rod 5, several abutting threaded rods 5 clamp and hold the welding arms. The third limiting nut 13 is tightened to limit and fix the position of the abutting threaded rod 5. Subsequently, the two arm sheet metals are welded using welding equipment. When welding components, robot arms come in various shapes and sometimes bend. When welding such robot arms, it is sometimes necessary to adjust the height of the threaded rod 5. The height of the threaded rod 5 can be adjusted by sliding the second sliding block 9 in the second sliding groove 10. After the height of the threaded rod 5 is adjusted to the appropriate position, the second limiting nut 12, which is threaded to the side of the second threaded post 11, is locked to limit and fix the position of the second sliding block 9, further improving the applicability of the welding fixture. It is worth noting that in actual use, a splash guard can be installed at the welding end of the welding device to prevent spatter from splashing onto the side of the threaded rod 5 during welding, thereby improving the service life of the threaded rod 5.

[0031] Example 2

[0032] Please see Figure 1 , Figure 2 and Figure 5 This embodiment includes the above embodiment, and further includes: a fixed base 14 is fixedly installed on the lower part of the welding fixture table 1, and a drive motor 15 is provided at one end of the fixed base 14. The drive motor 15 is used to drive the two clamping seats 2 to move synchronously towards each other or away from each other. A main controller 21 for controlling the drive motor 15 is provided on one side of the welding fixture table 1. A connecting frame 22 adapted to the fixed base 14 is fixedly installed on the side of the clamping seat 2. A third sliding block 16 is fixedly installed at the lower end of the connecting frame 22. A third sliding groove 17 adapted to the third sliding block 16 is opened on the upper part of the fixed base 14. A drive screw 18 with one end fixedly installed to the output end of the drive motor 15 is rotatably connected in the third sliding groove 17. The drive screw 18 passes through the third sliding block 16 and is threadedly connected to it. A pressing pad 19 is provided at one end of the pressing threaded rod 5. A polygonal rotating block 20 is provided at one end of the pressing threaded rod 5.

[0033] In this specific embodiment, when welding the same model of robot arm, the positions of the first sliding block 3 and the threaded rod 5 are adjusted. When clamping and welding the robot arm is required, the main controller 21 turns on the drive motor 15. The output end of the drive motor 15 drives the drive screw 18 to rotate. The threads of the drive screw 18 located on the inner side of the third sliding groove 17 are symmetrical and opposite. When the drive screw 18 rotates, it drives the two third sliding blocks 16 to move towards each other in the third sliding groove 17. The third sliding blocks 16 drive the connecting frame 22 to move, and the connecting frame 22 drives the clamping seat 2 to move, thereby causing the threaded rod 5 to be clamped on the side of the robot arm sheet metal, improving the welding efficiency. The welding efficiency of industrial robots is improved, and the stability of the robot arm is enhanced when clamping it by installing the clamping pad 19 at the end of the clamping threaded rod 5. When adjusting the position of the clamping threaded rod 5, the clamping threaded rod 5 is rotated by engaging a wrench in the position of the rotating block 20, which facilitates the rotation of the position of the clamping threaded rod 5. It is worth noting that when welding the sheet metal parts of the clamped robot arm, a splash guard can be installed at the welding head position of the welding device, or a protective device similar to an accordion can be installed at the position of the third sliding groove 17 to prevent welding spatter from splashing onto the side of the third sliding groove 17 or the drive screw 18, effectively extending the service life of the welding fixture.

[0034] The drive motors 15 mentioned above can all be purchased from the market. They are mature technologies and have been fully disclosed, so they will not be repeated in the manual. The drive motors 15 are equipped with power connection lines, and they are electrically connected to the external main controller 21 and 220V phase voltage (or 380V line voltage) through the power connection lines. The main controller 21 can be a conventional known device such as a computer that plays a control role.
