Description

Technical Field

[0001] The invention relates to the technical field of painting fixtures, and in particular to an adjustable combined painting fixture for an aluminum side-opening tailgate of an automobile. Background Art

[0002] In recent years, as tourism has gradually become a daily consumption for more and more people, self-driving tours, with their advantages of high freedom and flexibility, are more in line with people's pursuit of personalized and diversified tourism consumption experiences. As a result, hard-core off-road vehicles suitable for outdoor environments are becoming more and more popular. The side-opening tailgate is a classic configuration of hard-core off-road vehicles. In the automobile manufacturing process, the white body enters the painting workshop from the welding workshop. The side-opening tailgate is different from the ordinary lift-up tailgate or fold-down tailgate. Its hinge is connected to the D-pillar of the body on one side, and the side-opening tailgate can swing freely around the hinge. Therefore, for the white body after electrophoresis baking, it is usually necessary to connect the side-opening tailgate and the D-pillar of the body through a painting fixture to achieve: (1) The side-opening tailgate and the D-pillar of the body form a stable small angle opening to meet the needs of robot spraying and the side-opening tailgate and the body are non-stick paint. (2) The side-opening tailgate can be opened and closed freely around the hinge to meet manual operations such as plugging holes, gluing, and inner surface painting. With the automotive industry's trend toward lightweighting, aluminum is increasingly being used in vehicle design and manufacturing, comprising a growing proportion of the metal material used in body-in-white (BIW). Aluminum doors are particularly widely used. In the design and manufacturing of mid- to high-end vehicles both domestically and internationally, aluminum door painting fixtures typically use disposable plastic jigs. These are expensive, non-reusable, and waste plastic jigs can easily cause environmental pollution, violating the concept of green environmental protection. Furthermore, with the fluctuating domestic and international economic landscape and increasing pressure on the automotive sales side, cost reduction is a critical issue for automakers now and for a long time to come. Using stainless steel jigs, which can be cleaned and recycled, is a cost-saving solution preferred by many automakers.

[0003] However, hard-core off-road vehicles belong to a niche market, and aluminum tailgates are not widely used in practice. Therefore, there are almost no metal-based aluminum side-opening tailgate painting fixtures that can be used as reference at home and abroad, and independent innovative designs are needed. Summary of the Invention

[0004] The purpose of the present invention is to provide an adjustable combined automobile aluminum side-opening tailgate painting fixture to solve the problem that the existing automobile aluminum side-opening tailgate painting fixture cannot be recycled.

[0018] The above structural design facilitates clamping of the first bolt 21 , and the trumpet-shaped opening formed by the sixth bending section 435 and the third bending section 42 facilitates entry of the first bolt 21 into the clamping space 48 , thereby improving operational convenience.

[0019] The adjustable, modular aluminum side-opening tailgate painting fixture features a first spring clip 42 and a second spring clip 43, which are used to position the fixture in either an assembled or disassembled state, thereby enabling the side-opening tailgate inner panel 12 to be opened, closed, and positioned relative to the vehicle body's D-pillar sheet metal 11. The first spring clip 42 and the second spring clip 43 are permanently connected to the first bolt 21. When the side-opening tailgate inner panel 12 moves in a closing motion along with the tailgate hinge, the first spring clip 42 and the second spring clip 43 engage and clamp the first bolt 21, securing the side-opening tailgate inner panel 12 at a small angle relative to the vehicle body's D-pillar sheet metal 11. When the side-opening tailgate inner panel 12 moves in an opening motion along with the tailgate hinge, the first spring clip 42 and the second spring clip 43 disengage from the first bolt 2, allowing the side-opening tailgate to open freely around the tailgate hinge, facilitating manual operation. The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
