Description

Technical Field

[0001] This utility model relates to the field of automotive seat frame processing technology, specifically an automotive seat frame processing fixture. Background Technology

[0002] The car seat frame is a crucial component of a car seat, bearing its main structure and providing passengers with a comfortable and safe riding experience. The car seat frame includes the backrest frame, seat cushion frame, headrest frame, slide rails, and other components. The two main parts are the backrest frame and the seat cushion frame, which form the main framework of the car seat frame. The car seat frame is typically composed of metal tubes, steel plates, and welded parts. Its design and manufacturing quality directly affect the strength and stability of the seat. Welding the seat frame is a critical step in the car seat production process, requiring the use of clamps to hold and fix the frame to ensure welding quality and efficiency. A search revealed that a typical example of a car seat frame welding clamp in the prior art is application number CN202421164329.7, which describes a car seat frame... A welding fixture for automotive seat frames includes a base with eight clamping components mounted on top and a support mechanism on the base. Each clamping component includes a fixed box with a bidirectional threaded short rod rotatably connected to its top. Two clamping plates are threaded onto the bidirectional threaded short rod, with one side of each clamping plate slidingly extending outside the fixed box. Side plates are fixedly connected to both sides of each clamping plate. This invention relates to the field of welding fixture technology. This automotive seat frame welding fixture, by using eight clamping components, can clamp and fix the automotive seat frame at multiple points. Simultaneously, the support mechanism allows for the rational arrangement of the clamping components, enabling simultaneous fixation of the horizontal seat cushion frame and the vertical backrest frame, facilitating subsequent welding and improving usability.

[0003] In summary, when clamping and fixing both the car seat backrest frame and the car seat cushion frame simultaneously, to facilitate welding operations on other structures of the frame, especially the car seat backrest frame, if the clamping structure described in the above document is used to clamp the car seat backrest frame and the car seat cushion frame vertically, the gap between the car seat backrest frame and the car seat cushion frame after clamping is unclear, and the gap between the car seat backrest frame and the car seat cushion frame after clamping cannot be adjusted to increase, which affects the operation when welding the car seat backrest frame.
