[0032] 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.

[0033] Reference Figures 1-5 This utility model provides an embodiment of an anti-deviation positioning device for ultrasonic piercing welding of car bumpers, comprising a lathe 1, a reinforcing frame 3 fixedly connected to the top side of the lathe 1, a fixing frame 4 fixedly connected to the top side of the reinforcing frame 3, a bolt 5 threadedly connected to the outer side of the fixing frame 4, and a bolt 5 threadedly connected to the outer side of the reinforcing frame 3 inside the bolt 5. The fixing frame 4 and the bolt 5 are securely installed. The sliding main plate 9 on the sliding block 2 and the sliding shaft 11 on the inner side of the sliding auxiliary plate 8 can slide stably, and the buffer balls 18 on both sides and the baffle 16 on the stop frame 17 form a buffer, which can effectively prevent the device from deviating and ensure the positioning accuracy and operational stability of ultrasonic piercing welding of car bumpers. The top side of the fixing frame 4 is fixedly connected to a sliding main plate 9 on the sliding block 2 and the sliding shaft 11 on the inner side of the sliding auxiliary plate 8. The sliding block 2 has a sliding groove rod 10 fixedly connected to its top side, a reset component installed on its top side, multiple evenly distributed baffles 17 fixedly connected to its left and right sides, baffles 16 fixedly connected to the outside of the baffles 17, a sliding main plate 9 slidably connected to the outside of the sliding block 2, a sliding auxiliary plate 8 slidably connected to the outside of the sliding block 2, damping balls 18 fixedly connected to both sides of the sliding auxiliary plate 8, and damping balls 18 fixedly connected to both sides of the sliding main plate 9. When the damping balls 18 contact the baffles 16, they absorb vibration energy through elastic deformation, reducing the offset amplitude of the sliding component.

[0034] Reference Figures 2-5 A mechanical base 19 is fixedly connected to the top side of the sliding main board 9. A rotating shaft 20 is rotatably connected to the top side of the mechanical base 19. A drive arm 13 is rotatably connected to the top side of the rotating shaft 20. A large arm 21 is rotatably connected to the top side of the drive arm 13. A vertical shaft 22 is rotatably connected to the top side of the large arm 21. A drive head 23 is rotatably connected to the top side of the vertical shaft 22. The rotating shaft 20, drive arm 13, large arm 21, vertical shaft 22 and drive head 23 are linked in sequence to realize the flexible movement and precise positioning of welding-related components in three-dimensional space, meeting the welding needs of different positions and angles of the car bumper.

[0035] Reference Figures 3-5The reset assembly includes a base 35, which is rotatably connected to the top side of the sliding block 2. A reset plate 14 is rotatably connected to the top side of the base 35. A transfer cylinder 12 is rotatably connected to the top side of the reset plate 14. A turntable 15 is rotatably connected to the top side of the transfer cylinder 12. The reset plate 14 drives the transfer cylinder 12 to rotate, and the transfer cylinder 12 drives the turntable 15 to rotate, thereby enabling the device to automatically reset during operation and improving the convenience and continuity of welding operations. A shock-absorbing shaft 6 is fixedly connected to the top side of the fixed frame 4. A buffer rod 7 is slidably connected to the top side of the shock-absorbing shaft 6. The buffer rod 7 is slidably connected to the bottom side of the sliding main plate 9 and the bottom side of the sliding auxiliary plate 8.

[0036] Reference Figures 1-2 The drive head 23 is fixedly connected to the universal joint 24 at the front. The forearm 25 is fixedly connected to the outside of the universal joint 24. The eccentric head 26 is rotatably connected to the outside of the forearm 25. The drive disk 27 is rotatably connected to the outside of the eccentric head 26. The drive head 23 drives the universal joint 24 to rotate, the universal joint 24 drives the forearm 25 to rotate, the forearm 25 drives the eccentric head 26 to rotate, and the eccentric head 26 drives the drive disk 27 to rotate, thereby realizing the linkage of multiple components. This allows the welding head 33 and the piercing welding head 34 to flexibly adjust their angles and positions to adapt to complex welding conditions.

[0037] Working principle: First, with the synergistic effect of the reinforcing frame 3, the fixing frame 4 and the bolt 5, the sliding block 2 is firmly installed on the top side of the lathe 1, laying a stable foundation for the subsequent welding operation. Then, the sliding main plate 9 and the sliding auxiliary plate 8 begin to slide on the outside of the sliding block 2. During this process, the damping balls 18 on the left and right sides play a key role. Through their own buffering characteristics, they effectively reduce the impact generated during sliding and ensure that the sliding process is smooth and stable. At the same time, the reset assembly starts to operate. The base 35, the reset plate 14, the transfer cylinder 12 and the turntable 15 cooperate with each other to precisely adjust the sliding main plate 9 and the sliding auxiliary plate 8 to the designated position.

[0038] Subsequently, the robotic arm structure on the top side of the sliding motherboard 9 enters the working state. The mechanical base 19 serves as the basic support, and the rotating shaft 20, drive arm 13, large arm 21, vertical shaft 22, and drive head 23 move in sequence. With the flexible rotational connection between the components, the robotic arm can achieve multi-dimensional movement in space, thereby gradually adjusting the position of the welding head 33 and the piercing welding head 34. At the front end of the drive head 23, the universal shaft 24, forearm 25, eccentric head 26, drive disk 27, and rotating disk 28 further cooperate to make more precise adjustments to the posture and position of the welding head 33 and the piercing welding head 34. The deflection shaft 29 rotates to further fine-tune the angle and position of the welding head 33 and the piercing welding head 34. The drive box 30 provides power support for the welding operation, driving the welding head 33 and the piercing welding head 34 to vibrate at high frequency, thereby realizing ultrasonic piercing welding. The quick-release cover 31 facilitates the quick disassembly and replacement of the welding head 33 and the piercing welding head 34 by the staff, improving the maintenance efficiency of the equipment. The welding tube 32 serves to transmit energy and protect the internal structure, thereby enabling extremely precise alignment with the welding points of the car bumper.

[0039] 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.
