Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a welding device for automotive stamping parts. Background Technology

[0002] In the automotive manufacturing industry, stamped parts are an important component of the car body. They are usually stamped by molds and have complex shapes and precision requirements. Welding technology is widely used to combine multiple stamped parts together.

[0003] In traditional techniques, polishing is usually performed as a separate step after welding, which requires additional equipment and labor costs. If polishing is not done in time, welding marks will remain, affecting the appearance and surface quality of the product. At the same time, traditional welding techniques usually require a lot of manual operation, which not only increases labor costs but also reduces production efficiency. In order to solve the above problems, this utility model provides a welding device for automotive stamping parts. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a welding device for automotive stamping parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A welding device for automotive stamping parts includes a worktable with a groove on its upper surface. A first threaded screw is rotatably connected inside the groove. A movable seat is threadedly fitted onto the surface of the first threaded screw. A mounting plate is fixedly connected to the upper surface of the movable seat. Clamping assemblies are fixedly connected to both sides of the mounting plate. A support plate is fixedly connected to the upper surface of the worktable. A mounting bracket is fixedly connected to the front of the support plate. A second threaded screw is rotatably connected inside the mounting bracket. A lifting seat is threadedly fitted onto the surface of the second threaded screw. A welding assembly is fixedly connected to the front of the lifting seat.

[0007] As a further improvement of this utility model, the clamping assembly includes a first electric push rod fixedly connected to both sides of the mounting plate, and a U-shaped plate fixedly connected to the telescopic ends of the two first electric push rods. A cylinder is fixedly connected to the upper surface of the U-shaped plate, and a clamping plate is fixedly connected to the telescopic end of the cylinder.

[0008] As a further improvement of this utility model, the welding assembly includes a fixed base fixedly connected to the front of the lifting seat, a welding head fixedly connected to the lower end of the fixed base, an mounting base fixedly connected to the front of the fixed base, a second electric push rod fixedly connected inside the mounting base, a polishing motor fixedly connected to the telescopic end of the second electric push rod, and a polishing disc fixedly connected to the power end of the polishing motor.

[0009] As a further improvement of this utility model, a first drive motor is fixedly connected to the back of the support plate, and the power end of the first drive motor is fixedly connected to a first threaded screw.

[0010] As a further improvement of this utility model, a second drive motor is fixedly connected to the upper surface of the mounting bracket, and the power end of the second drive motor is fixedly connected to the second threaded screw.

[0011] As a further improvement of this utility model, a welding machine is fixedly connected to the back of the support plate, a connecting pipe is fixedly connected to the upper end of the welding machine, and the other end of the connecting pipe is fixedly connected to the welding head.

[0012] The beneficial effects of this utility model are:

[0013] By setting up a clamping assembly, the device can be flexibly adjusted according to different sizes of automotive stamping parts. This ensures that each stamping part can be firmly clamped, providing a stable positioning basis for subsequent welding operations, improving the convenience of operation, and enhancing the versatility and applicability of the equipment.

[0014] By setting up a movable seat and a lifting seat, when in use, the second drive motor is started to drive the second threaded screw to rotate, realizing the precise up and down movement of the lifting seat, thereby accurately positioning the welding head to the welding point of the automotive stamping part. Combined with the back and forth movement of the movable seat driven by the first drive motor, it is possible to achieve precise welding of different positions of the stamping part, which not only improves the accuracy and efficiency of welding, but also ensures the consistency of welding quality and reduces welding defects caused by positional deviation.

[0015] By setting up welding components, after welding is completed, the second electric push rod is activated to drive the polishing disc to descend and align with the welding point. Then, the polishing motor is activated to perform the polishing operation. This simplifies the workflow by integrating the two key steps of welding and polishing. This not only saves time and labor costs but also helps to improve overall work efficiency. At the same time, timely polishing can effectively remove welding marks and improve the aesthetics and surface quality of the product.

[0016] In summary, this invention relies heavily on the precise control of automated components from clamping and positioning to welding and polishing, reducing manual intervention and achieving automation, efficiency, and precision in the welding process of automotive stamping parts. This improves production efficiency and product quality while reducing operational difficulty and costs. Attached Figure Description

The telescopic ends of the two first electric push rods 10 are fixedly connected to U-shaped plates 11. The design of the U-shaped plates 11 allows the clamping plates 13 to move flexibly in the vertical direction to adapt to stamping parts of different heights. A cylinder 12 is fixedly connected to the upper surface of the U-shaped plates 11. The cylinder 12 serves as a power source to provide sufficient clamping force to ensure that the stamping parts will not move or loosen during the welding process. The telescopic ends of the cylinder 12 are fixedly connected to the clamping plates 13. The clamping plates 13 are made of wear-resistant materials to increase service life and reduce damage to the stamping parts.

[0025] The welding assembly includes a fixed base 14 fixedly connected to the front of the lifting base 9.

The welding head 15 is fixedly connected to the lower end of the fixed base 14, and a mounting base 16 is fixedly connected to the front of the fixed base 14. The mounting base 16 provides a stable mounting foundation for the second electric push rod 17. The second electric push rod 17 is fixedly connected inside the mounting base 16. The second electric push rod 17 is responsible for driving the polishing disc 19 to move up and down, realizing the automation of the polishing operation. A polishing motor 18 is fixedly connected to the telescopic end of the second electric push rod 17. The polishing motor 18 provides the power required for polishing, and its speed is adjustable to adapt to different polishing needs.

Then, the cylinders 12 on the two U-shaped plates 11 are activated to move the two clamping plates 13 downward until the automotive stamping part is fixed. Next, the second drive motor 21 is activated to rotate the second threaded screw 8, thereby driving the lifting seat 9 to move up and down until the welding head 15 is lowered to the welding point of the automotive stamping part. The welding machine 22 is activated to perform welding through the welding head 15. At the same time, the first drive motor 20 is activated to rotate the first threaded screw 3, driving the movable seat 4 to move back and forth. The movable seat 4 moves the automotive stamping part on the mounting plate 5, thereby performing welding on different positions of the automotive stamping part. Finally, after welding is completed, the second electric push rod 17 is activated to move the polishing disc 19 downward until it is aligned with the welded position.
