Description
Technical Field
[0001] The utility model relates to the technical field of automobile component processing, and more specifically, to a device capable of effectively preventing leakage welding of welding nuts of automobile seat crossbeam brackets. Background Art
[0002] The car seat crossbeam bracket is an important supporting structure at the bottom of the car seat or on both sides of the seat back. It can provide stable support for the seat, ensuring that the seat remains stable and does not shake during driving. It can also improve the riding comfort and safety of passengers and avoid accidents caused by unstable seats. It is an important part of the car.
[0003] In the production process of automobile seat crossbeam brackets, the step of welding nuts is directly related to the safety performance of the seat. Currently, when welding the nuts, the product part is first clamped and fixed. After the first nut is welded, the product part is rotated and the second nut is welded. In this traditional projection welding process, repetitive operations will cause personnel fatigue. When personnel are tired or new employees are negligent in their work, they are likely to forget to rotate, resulting in an accident of leaking a nut, which can easily cause great hidden dangers to automobile assembly. At present, when the problem of leaking welding occurs, it will increase the difficulty of personnel detection and increase the workload of the staff. In addition, the nuts are welded one by one, and the production efficiency is low, which cannot meet the customer's production capacity. Therefore, there is a need for a device that can effectively prevent the leaking welding of the nuts of the automobile seat crossbeam bracket. Utility Model Content
[0004] In order to overcome the deficiencies of the prior art, the utility model provides a device that can effectively prevent welding leaks on welding nuts of a crossbeam bracket of an automobile seat, and has the advantage of preventing welding leaks.
