[0003] However, the existing spraying fixtures have the following drawbacks in actual use: 1. The structure is relatively fixed and cannot be customized according to the different sizes of different internal and external trim parts, resulting in frequent replacement of different spraying fixtures on the spraying production line to adapt to trim parts of different sizes; 2. It is inconvenient to disassemble and assemble the various components of the spraying fixture, and it is inconvenient to disassemble and replace easily worn components; 3. The support and positioning components are not convenient to assemble and add or remove according to requirements. Utility Model Content

[0006] In this way, in the above-mentioned automotive interior and exterior trim painting fixture structure, by inserting the connecting blocks on the longitudinal rods of the fixture into the connecting holes arranged longitudinally along the bottom support frame in different sets that are matched with the support beam, the structure of the automotive interior and exterior trim painting fixture can be specifically assembled and modified, changing the spacing between two adjacent longitudinal rods of the fixture. This allows it to adapt to different interior and exterior trim parts, reduce the frequency of fixture replacement on the painting production line, and improve painting efficiency.

[0007] As an optimization, the supporting crossbeams are two arranged at intervals; the hanging fixture longitudinal rods are four arranged at intervals.

[0008] In this way, the arrangement of the number of supporting beams is more reasonable, and the arrangement of the number of hanging fixture longitudinal bars is more reasonable.

[0009] As an optimization, the plug-in connection hole is a rectangular hole, the cross-section of the plug-in connection block is designed with a rectangular structure, and the lower end face of the plug-in connection block is provided with a chamfer structure.

[0010] In this way, designing the plug-in connection hole as a rectangular hole and the cross-section of the plug-in connection block as a rectangular shape can better prevent rotation and improve reliability; the chamfered structure design can make assembly easier.

[0013] As an optimization, the bottom support frame further includes two support longitudinal beams arranged at intervals, and a support crossbeam is disposed between the two support longitudinal beams; and the ends of the support crossbeams are respectively welded to the inner side of the support longitudinal beams.

[0014] This makes the bottom support frame's structural design simpler and more reasonable, and better ensures stability.

[0015] As an optimization, the cross sections of the supporting crossbeam, supporting longitudinal beam, and hanging fixture longitudinal rod are all designed with a rectangular structure.

[0016] In this way, the cross-sectional design of the supporting beams, supporting longitudinal beams, and hanging fixture longitudinal bars is more reasonable.

[0017] As an optimization, 10 plug-in connection holes are arranged at intervals along the length of the supporting beam.

[0018] In this way, the number of plug-in connection holes is designed more reasonably, which can better combine different sizes and shapes, and better adapt to different sizes of internal and external trim parts.

[0019] As an optimization, the support positioning component includes a first positioning rod connected and fixed to the longitudinal rod of the hanging fixture; a second positioning rod is provided above the first positioning rod, and the lower end face of the second positioning rod has a sleeve hole, the first positioning rod can extend into the sleeve hole of the second positioning rod, and the lower end face of the second positioning rod can be attached to the upper surface of the longitudinal rod of the hanging fixture.

[0020] In this way, the structural design of the supporting positioning components is simpler and more reasonable, making it easier to disassemble and replace, and better adaptable to the placement and support of different internal and external decorative parts; it can also be assembled and added or removed as needed.

[0021] As an optimization, the cross-section of the first positioning rod is designed as a regular hexagon, and the socket is designed as an internal hexagonal hole.

[0022] This better restricts the rotation of the first and second positioning rods, resulting in a more rational structural design.

[0023] As an optimization, the lower end of the first positioning rod has a threaded fixing section, and the threaded fixing section is threadedly connected and disposed in the threaded fixing hole of the longitudinal rod of the hanging fixture.

[0024] This makes it easier to assemble and disassemble the first positioning rod.

[0025] Furthermore, both the first and second positioning rods have a hexagonal cross-section design.

[0026] In summary, the aforementioned automotive interior and exterior trim painting fixtures feature a simpler and more rational structural design, are easier to assemble and adjust to better adapt to different trim parts, and allow for easier assembly, addition, or removal of fixture support and positioning components.
