Description

Technical Field

[0001] The present application relates to the field of longitudinal beam electrophoresis tooling, and in particular, to an electrophoresis frame structure. Background Art

[0002] As truck users have an increasing demand for vehicle durability, OEMs use a single-piece electrophoresis process for the longitudinal beam to solve the problem of interlayer corrosion in the frame assembly. When using the intermittent electrophoresis process design, tooling with the longitudinal beam opening placed downward is often used.

[0003] Although the longitudinal beam opening downward assembly method is easier to achieve multi-variety automatic assembly, it has the following problems:

[0004] (1) The inner ventral surface of the downward longitudinal beam is blocked by many surrounding areas, resulting in poor circulation cleaning at this location. The bubbles generated on the surface during the electrophoresis process cannot be discharged, resulting in bubble hole defects in the electrophoretic coating on the inner ventral surface.

[0005] (2) Since the inner belly surface of the longitudinal beam placed in the middle position is obstructed by many obstacles, the circulation cleaning of the longitudinal beam at this position is poor, and the drawing oil on the surface of the longitudinal beam is difficult to be completely washed off. After electrophoresis, there are shrinkage defects on the inner belly surface.

[0006] (3) There are many shielding around the middle of the inner belly of the longitudinal beam, which leads to the weakening of the electric field strength at this position and the thinning of the coating thickness, which is about 10-20μm, and does not meet the standard requirements.

[0043] Example 1

[0044] An electrophoresis frame structure, comprising: an electrophoresis frame bracket 1; two groups of longitudinal beam support structures 2 are arranged on the electrophoresis frame bracket 1; each group of the longitudinal beam support structures 2 includes two groups of longitudinal beam support assemblies 20 arranged at the same height on the electrophoresis frame bracket 1; each group of longitudinal beam support assemblies 20 includes: a longitudinal beam bracket 201 arranged on the electrophoresis frame bracket 1, a plurality of longitudinal beam spacers 202 evenly arranged along the length direction of the longitudinal beam bracket 201, and a plurality of anti-slip positioning parts 203; wherein, a plurality of supporting surfaces are symmetrically and continuously arranged on the upper end surfaces of the two side walls in the length direction of the longitudinal beam bracket 201; an anti-slip positioning part 203 is arranged in the middle of each pair of symmetrical supporting surfaces; a longitudinal beam spacer 202 is fixedly arranged on the upper part of the longitudinal beam bracket 201 corresponding to the two end positions of each pair of supporting surfaces; wherein, two adjacent longitudinal beam spacers 202, a pair of supporting surfaces symmetrically located between the two longitudinal beam spacers 202, and the anti-slip positioning parts 203 corresponding to the supporting surfaces together constitute a longitudinal beam accommodating gap. The opening angle of each support surface is 150°-170°. Wherein, the support surface is a V-shaped support surface.

[0045] Specifically, the longitudinal beams are supported by each set of longitudinal beam support structures 2; wherein the spacing distance between the two sets of longitudinal beam support components 20 included in each set of longitudinal beam support structures 2 can be adapted according to the length of the longitudinal beams.

[0046] It can be understood that the present application places the longitudinal beam on its side in the accommodation gap between two longitudinal beam spacers 202, and contacts the bottom surface of the side wall of the longitudinal beam through the support surface, so that the bottom surface of the side wall of the longitudinal beam forms an angle of 10-20° with the horizontal direction, thereby reducing the contact area between the longitudinal beam and the longitudinal beam support assembly 20, avoiding defects such as bubbles and shrinkage holes during electrophoresis, and poor electrophoresis of the longitudinal beam contact surface, thereby improving the electrophoresis effect and efficiency of the longitudinal beam; at the same time, the present application avoids the problem of poor stability of the longitudinal beam on the support surface when the longitudinal beam is installed in the accommodation gap, and ensures the stability of the longitudinal beam by installing an inverted U-shaped anti-slip positioning portion 203 in the central recessed portion of the support surface.

[0051] Since the electrophoretic longitudinal beam of the present application requires a heavier mass, in order to ensure the overall firmness and stability of the longitudinal beam bracket 201, the longitudinal beam bracket 201 of the present application is further optimized. Among them, each of the support vertical plates 2011 of the present application is provided with a plurality of welding protrusions 2015 at the bottom, and correspondingly, corresponding positions on both sides of the support bottom plate 2010 are provided with welding grooves 2016 that cooperate with the welding protrusions 2015 for limiting and plugging; the support bottom plate 2010 is plugged and matched with the welding grooves 2016 through the welding protrusions 2015 and is fixed to the bottom of the support vertical plate 2011 by welding; a plurality of square welding holes 2017 are provided on the side wall of each of the support vertical plates 2011, and correspondingly, corresponding positions on both sides of the support cross plate 2012 are provided with positioning protrusions 2018 that cooperate with the welding holes 2017 for limiting and plugging; the support cross plate 2012 is plugged and matched with the welding holes 2017 through the positioning protrusions 2018 on both sides, and is fixed between the two support vertical plates 2011 by welding.
