Spraying fixture for automotive trim strips

Abstract

The invention relates to a jig applied to production of automobile parts, in particular to a spray coating jig for automobile upper panels. The spray coating jig comprises two supporting cross beams, a supporting longitudinal beam I and a supporting longitudinal beam II, and the supporting longitudinal beam I and the supporting longitudinal beam II are connected between the two supporting cross beams. The spray coating jig further comprises a positioning supporting rod, multiple pairs of plate positioning and clamping devices and multiple pairs of hole positioning and clamping devices, wherein the positioning supporting rod comprises a supporting rod and connection rods formed by downwards bending and extending the two ends of the supporting rod; the connection rods at the two ends of the supporting rod are connected to the upper surfaces of the two supporting cross beams correspondingly; the multiple pairs of plate positioning and clamping devices are evenly distributed on the upper surface of the supporting longitudinal beam I, and the bottom ends of the multiple pairs of plate positioning and clamping devices are fixedly connected with the upper surface of the supporting longitudinal beam I; the multiple pairs of hole positioning and clamping devices are evenly distributed on the upper surface of the supporting longitudinal beam II, and the bottom ends of the multiple pairs of hole positioning and clamping devices are fixedly connected with the supporting longitudinal beam II; the plate positioning and clamping devices are of the same number with the hole positioning and clamping devices. The spray coating jig has the advantages of being capable of clamping and positioning upper panels and guaranteeing the product quality, convenient to move and the like.

Description

technical field [0001] The invention relates to a jig used in the production of auto parts, in particular to a jig for spraying decorative strips on automobiles. Background technique [0002] The upper decorative strip of the car is formed by plastic injection molding. After molding, the upper decorative strip needs to be sprayed, and after spraying, it needs to be baked. The jig without positioning is very inconvenient in the process of spraying and baking. For this reason, the commonly used method in the industry It is to make a support frame, and then place the unpainted top trim on the support frame. After spraying, move the support frame and the top trim together to the oven for baking. This kind of support frame has no clamps on the top trim. Due to the tight positioning function, the upper decorative strip is easy to fall or shift from the supporting frame during the construction process, which will easily affect the quality of spraying and baking paint. In addition, ...
