Specific embodiments

[0029] The technical scheme in the embodiments of the utility model will be described clearly and completely in conjunction with the drawings in the embodiments of the utility model below, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.

[0030] Reference Figures 1-3This utility model provides an embodiment of an automotive bumper welding fixture, comprising a base 1. The base 1 is configured to support the movement of a slider 4 and the rotation of a lead screw 5. A slider 4 is slidably connected to the upper inner wall of the base 1, providing support for the installation of a fixed post 8. The slider 4 drives the fixed post 8 to move through the rotation of the lead screw 5. A fixed post 8 is fixedly connected to the upper outer wall of the slider 4. A limit hole is formed on the inner wall of the front end of the fixed post 8, providing support for the movement of a moving block 7. A moving block 7 is slidably connected through the outer wall of the fixed post 8. Block 7 slides on the outer wall of the fixed column 8, causing the pressure block 18 to move. A limit block 6 is elastically connected to the inner wall of the front end of the moving block 7 via a spring 17. The left rear end of the limit block 6 is cylindrical. One end of the spring 17 is fixed to the cylindrical side wall of the limit block 6. The outer rear end wall of the limit block 6 engages with the inner front end wall of the fixed column 8 to fix the position of the moving block 7. When the outer rear end wall of the limit block 6 leaves the inner front end wall of the fixed column 8, the limitation on the moving block 7 is released. The outer rear end wall of the limit block 6 is slidably connected to the inner front end wall of the moving block 7. A spring 17 is snapped onto the inner wall of the front end of the fixed post 8. One end of the spring 17 is fixedly connected to the inner wall of the front end of the movable block 7, and the other end of the spring 17 is fixedly connected to the side wall of the limiting block 6. A threaded rod 9 is threaded through and connected to the inner wall of the upper end of the movable block 7. The rotation of the threaded rod 9 can drive the pressure block 18 to move, allowing for fine adjustment of the position of the pressure block 18. A pressure block 18 is rotatably connected to the outer wall of the bottom end of the threaded rod 9. The pressure block 18 is used to press down on the upper side of the bumper body 10 to fix the bumper body 10. The right outer wall of 8 is slidably connected to the left inner wall of the movable block 7. An electric telescopic rod 11 is fixedly connected to the upper outer wall of the base 1. A top block 12 is fixedly connected to the upper outer wall of the electric telescopic rod 11. The top block 12 moves upward by the operation of the electric telescopic rod 11 to adjust the height of the bumper body 10. The bumper body 10 is placed on the upper outer wall of the top block 12. A drive assembly is provided on the upper inner wall of the base 1. The drive assembly is used to drive the slider 4. A moving assembly is provided on the bottom inner wall of the base 1. The moving assembly is used to move the device.

[0031] Reference Figure 1 and Figure 2The moving component includes an electric telescopic rod 14, which is used to move the connecting block 15. The movement of the connecting block 15 drives the movement of the fixed rod 16. The connecting block 15 is fixedly connected to the bottom outer wall of the electric telescopic rod 14. The connecting block 15 drives the fixed rod 16 to move through the operation of the electric telescopic rod 14. The fixed rod 16 is fixedly connected to the front outer wall of the connecting block 15. The fixed rod 16 provides support for the rotation of the pulley 3. The pulley 3 is rotatably connected to the outer wall of the fixed rod 16. The fixed block 2 is fixedly connected to the front outer wall of the base 1. The fixed block 2 is used to protect the pulley 3. At the same time, the fixed block 2 can increase the contact area with the ground and prevent the base 1 from tipping over. There are four fixed blocks 2, and every two fixed blocks 2 form a group.

[0032] Reference Figure 1 and Figure 2 The drive assembly includes a motor 13, which drives the lead screw 5 to rotate. The motor 13 is fixedly connected to the upper inner wall of the base 1. The lead screw 5 is rotatably connected to the inner wall of the base 1. The lead screw 5 drives the slider 4 to move through the motor 13. The outer wall of the lead screw 5 is threaded and connected to the inner wall of the front end of the slider 4. There are two symmetrical lead screws 5. The inner wall of the left end of the lead screw 5 is fixedly connected to the output shaft of the motor 13.

[0033] Working principle: By activating the electric telescopic rod 14, the base 1 moves upward, exposing the pulley 3. The lowest point of the pulley 3 is lower than the bottom outer wall of the base 1, allowing the device to move via the pulley 3. After movement, the electric telescopic rod 14 moves the base 1 downward until its bottom outer wall contacts the ground. The electric telescopic rod 11 then moves the top block 12 upward to a suitable position, placing the middle part of the bumper on the top block 12. Finally, the motor 13 is activated, causing the lead screw 5 to rotate. The rotation of the lead screw 5 drives the movement of the slider 4, adjusting the horizontal position of the pressure block 18. The moving limit block 6 moves away from the inner wall of the fixed column 8, and the moving block 7 moves the pressure block 18 downward to roughly adjust its position. After adjustment, the limit block 6 is released and locked onto the inner wall of the fixed column 8 to fix the position of the moving block 7. Then, the threaded rod 9 is rotated to move the pressure block 18 downward, so that the pressure block 18 contacts the upper outer wall of the bumper body 10, thus clamping the bumper body 10, and subsequent welding operations can be carried out.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
