However, with the development of the automobile industry, the automobile bumper, as an important safety device, has also entered the road of innovation. Today's front and rear bumpers of a sedan not only maintain the original protection function, but also pursue harmony and unity with the vehicle body styling and pursue lightweight of the bumper material. The local or partial thickness of the bumper material is less than 3mm, which has high requirements for the new type of automobile bumper material coating fixture.

[0003] After searching, it is found that the prior art such as the announcement number CN217043088U a coating fixture, including two horizontal beams in the form of curved rods, two to four connecting beams are fixedly connected between the horizontal beams, two to four blind holes are arranged on the connecting beams, and elastic clamps are arranged in the blind holes, one end of the elastic clamp is inserted into the blind hole, and the other end is supported in the groove on the side wall of the automobile bumper facing the inside of the automobile body after being tightened; four or six supporting columns are fixedly connected below the horizontal beams and / or connecting beams. The utility model combines the existing spraying clamp spring sheet with the existing coating fixture, reduces the number of beam columns in the original coating fixture, reduces the welding position, and can avoid the problem that the coating fixture is easily disconnected at the welding position during repeated cleaning and paint removal.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] Please refer to Figures 1-4 The utility model provides a kind of technical solutions: a coating jig of the welding point structure, four groups of connecting beams 2 are welded and fixed between two groups of cross beams 1, and two groups of lifting support frames 3 are welded and fixed below cross beam 1.

[0025] Further, the connecting beam 2 is provided with two groups of blind holes 201, and the blind holes 201 are matched with elastic clips. One end of the elastic clip is inserted into the blind hole 201, and the other end is supported in the groove of the side wall of the automobile bumper after being tightened. The elastic clip is made of stainless steel or aluminum alloy, and includes a middle plate and elastic sheets located on both sides of the middle plate. The distance between the ends of the elastic sheets on both sides is greater than the width of the groove. The position and structure of the groove of the side wall of the automobile bumper can be referred to the related content of CN217043088U, a coating jig.

[0026] Further, the cross beam 1 is integrally made of round steel, and the round steel is provided with a plurality of bending points 101.

[0027] Specifically, the lifting support frame 3 includes a base 301, and an open fixing cylinder 302 is arranged above the base 301. A support frame 303 is arranged inside the open fixing cylinder 302. Limiting sliding blocks 3031 are arranged on both sides of the bottom of the support frame 303, and the limiting sliding blocks 3031 are in sliding connection with limiting sliding rods 3032 arranged symmetrically inside the open fixing cylinder 302. The limiting sliding blocks 3031 and the limiting sliding rods 3032 can limit the movement of the support frame 303, thereby improving the stability of the support frame 303 during movement. The support frame 303 is connected to the bottom of the cross beam 1 outside the open fixing cylinder 302. Gear racks 304 are arranged on both sides inside the support frame 303, and the gear racks 304 are in meshing connection with gears 305 arranged rotatably inside the open fixing cylinder 302. The two groups of gears 305 are in meshing connection with each other. A driving motor 306 is arranged outside the open fixing cylinder 302 to drive one group of gears 305 to rotate.

[0028] In a further embodiment, bolt holes 3011 are symmetrically arranged on the base 301, so that the base 301 can be fixed by bolts in the later stage.

[0029] In a further embodiment, a protective cover 3061 is hingedly connected to the outside of the open fixing cylinder 302 and matched with the driving motor 306, so as to protect the driving motor 306 in the later stage. Magnets are arranged inside the protective cover 3061 and the open fixing cylinder 302 and are attracted to each other. The magnets can be used to limit and attract the protective cover 3061 when it is closed. A self-rotation prevention device is arranged at the output end of the driving motor 306 to prevent the output end of the driving motor 306 from rotating by itself.

[0030] When the height of the cross beam 1 and the welding point of the cross beam 1 needs to be adjusted, the driving motor 306 is started. Under the action of the driving motor 306, the gears 305 rotate to drive the gear racks 304 and the support frame 303 to move. Under the action of the movement of the support frame 303, the height of the cross beam 1 and the welding point of the cross beam 1 changes.

[0031] The terms "center", "longitudinal", "transverse", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which are only simplified descriptions for facilitating the description of the utility model, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the protection scope of the utility model.
