[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a stackable automobile beam rivet spraying fixture. Background Technology

[0002] In the automotive manufacturing industry, the car frame, as a core component that bears the weight of the vehicle body and transmits power, has its connection strength and durability directly related to vehicle driving safety. Rivets, as key fasteners connecting various components of the car frame, need to be coated with a protective coating to resist corrosion and wear damage during driving and ensure the long-term stability of the connection structure. In the traditional rivet coating process, due to the lack of special fixtures or unreasonable fixture design, problems such as inaccurate rivet positioning, insufficient coating coverage, and uneven coating thickness often occur, requiring fixtures for fixation.

[0003] In the field of automotive frame rivet spraying technology, traditional spraying fixtures have many technical limitations: their positioning structure mostly adopts a fixed design, which cannot flexibly adjust the clamping size according to the rivet specifications, resulting in poor adaptability. This leads to the need for special fixtures for different types of rivets, increasing equipment costs and management complexity; during spraying operations, the large area covered by the fixture makes it easy for some areas of the rivet not to be evenly covered by the paint, forming a protective blind spot and affecting the coating's corrosion protection effect on the rivet; in addition, the overall structure of the fixture lacks a stacking adaptation design, requiring a large amount of storage space when idle, reducing the space utilization rate of the workshop.
