[0025] In a further preferred embodiment of the present invention, the adjusting assembly includes a slider 10 threaded around the first threaded rod 8, a connecting plate 11 fixed to the top of the slider 10, and a cylinder 12 installed on the top of the connecting plate 11 for adjusting the height of the second adjusting plate 4, wherein the output rod of the cylinder 12 is connected to the second adjusting plate 4.

[0026] In this embodiment, the slider 10 achieves smooth and precise movement through a threaded connection, providing stable support and adjustment foundation for the connecting plate 11 and the cylinder 12 (ISO / VDMA cylinder). The cylinder 12 is used to adjust the height of the second adjusting plate 4. Through the extension and retraction movement of the cylinder 12, the height adjustment of the second adjusting plate 4 is achieved quickly and precisely, which facilitates the unloading and welding of bumper materials.

[0027] In a further preferred embodiment of the present invention, a support plate 19 for supporting and stabilizing the bumper material is fixed between the support frame 1 and the extension frame 14. A buffer pad for shock absorption is fixed on the top of the support plate 19. The support plates 19 are arranged in groups and are respectively located on both sides of the first adjustment plate 3.

[0028] In this embodiment, the support plate 19 is used to support and stabilize the bumper material, providing additional support force to ensure the stability and reliability of the bumper material during the welding process and prevent displacement or deformation caused by material weight or welding vibration. The buffer pad is used to reduce vibration and reduce the impact of vibration generated during welding on the bumper material. By absorbing and dispersing vibration energy, it protects the bumper material from damage caused by welding vibration, improves welding quality and yield. The grouped layout not only provides more comprehensive support but also enhances the stability and load-bearing capacity of the entire device.

[0029] In a further preferred embodiment of the present invention, hydraulic rods 15 are installed on both the support frame 1 and the extension frame 14.

The bottom of the first adjusting plate 3 is inlaid with balls that contact the top of the support frame 1 and the extension frame 14 to reduce friction.

[0030] In this embodiment, the position of the limiting plate 16 can be flexibly adjusted by the telescopic movement of the hydraulic rod 15 (EMG electric hydraulic actuator), so as to achieve precise positioning and fixing of the bumper material. This helps to maintain the accuracy of the position of the bumper material before fixing, thereby improving the accuracy of welding. The limiting plate 16 is used to assist in the positioning of the bumper material and prevent it from moving before fixing. The ball bearings can significantly reduce the friction of the first adjusting plate 3 during the movement, so that the adjusting plate can move more smoothly and stably.

[0031] In a further preferred embodiment of the present invention, a support leg is fixed to the bottom of the connecting plate 11, and a support wheel 13 for assisting the movement of the connecting plate 11 is rotatably mounted on the support leg. The support wheel 13 cooperates with the support leg to support the connecting plate 11 so as to maintain the smooth movement of the connecting plate 11. The support wheel 13 is covered with a rubber sleeve for shock absorption.

[0032] In this embodiment, the support leg provides stable support force, ensuring that the connecting plate 11 and its components such as the cylinder 12 and the second adjusting plate 4 can move smoothly and safely. The support wheel 13 can reduce the frictional resistance of the connecting plate 11 during movement, making the connecting plate 11 move more smoothly and easily. At the same time, the rotation of the support wheel 13 can also play a guiding role, ensuring the stability and accuracy of the connecting plate 11 during movement. The rubber sleeve can absorb and disperse the vibration and impact force generated during movement, protecting the support wheel 13 from damage.

[0033] In a further preferred embodiment of this utility model, an anti-slip pad for increasing friction is installed on the clamping plate 6, the anti-slip pad can contact the bumper, and the servo motor 9 and the reciprocating motor 18 are both covered with protective shells for isolating welding sparks.

[0034] In this embodiment, the anti-slip pad can increase the friction between the clamp 6 and the bumper, preventing the bumper from sliding or shifting due to vibration or external force during the welding process. This helps to ensure the stability and accuracy of the bumper during the welding process, improve welding quality and yield. Sparks and spatter may be generated during the welding process, which can damage or interfere with the normal operation of electronic equipment such as motors. The protective shell can isolate these sparks and spatter, protecting the motor from damage.

[0035] In a further preferred embodiment of the present invention, a support shaft is fixed on the output rod of the hydraulic rod 15 and rotatably connected to the limiting plate 16. A protective cylinder is installed on the limiting plate 16 and sleeved outside the support shaft. A limiting bolt for stabilizing the angle of the limiting plate 16 is threaded onto the protective cylinder.

[0036] In this embodiment, the support shaft provides a stable fulcrum for the limiting plate 16, allowing the limiting plate 16 to rotate flexibly within a certain range to adapt to bumper materials of different shapes and sizes. The protective sleeve can protect the support shaft from corrosion and damage from the external environment. By adjusting the tightness of the limiting bolts, the rotation angle of the limiting plate 16 can be limited, thereby achieving precise positioning and fixing of the bumper material.

[0037] In summary, compared with related technologies, this device achieves stable clamping of bumper raw materials by setting adjustable first adjustment plate 3 and second adjustment plate 4 on the support frame 1, in conjunction with electric telescopic rod 5 and clamping plate 6. At the same time, through components such as threaded rod, servo motor 9 and reciprocating motor 18 in the power structure, the distance between the two bumper raw materials can be precisely adjusted, realizing synchronous feeding and stability of the two bumper sections, effectively increasing welding efficiency. By adding adjustment components, support plate 19, hydraulic rod 15 and limit plate 16, the stability and flexibility of the device are further improved, ensuring the accuracy and efficiency of the welding process.
