Description

Technical Field

[0001] This utility model relates to the field of surface coating technology in automotive parts manufacturing, specifically a powder-coated hanging plate for automotive hangers. Background Technology

[0002] Currently, the surface coating of automotive hanger lugs all adopts electrostatic powder coating process, such as Figure 5 or Figure 6 The car hanger 5 shown has a surface powder-coated surface on the side with the recessed hole and its four adjacent sides. The remaining side is the mounting surface of the hanger 5, which is not powder-coated. When the hanger 5 is powder-coated, its non-powder-coated surface is tightly adhered to the surface. Figure 7 The hanging plate 1 shown is fixedly connected to the hanging plate 1. The lifting lug 5 enters the electrostatic powder coating equipment with the hanging plate 1 for powder coating. However, this hanging plate powder coating process has a defect. At the boundary line where the lifting lug 5 contacts the hanging plate 1, powder will accumulate during the powder coating process. This powder accumulation is uneven and the edges are irregularly serrated. During the use of the lifting lug 5, the powder coating is easy to fall off, which will affect the surface powder coating quality of the lifting lug 5 and the installation accuracy of the lifting lug 5. Utility Model Content

[0003] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a powder-coated mounting plate for automobile hangers, which effectively solves the problem of powder accumulation, improves the surface powder coating quality of the hangers, and enhances the installation accuracy of the hangers.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a powder-coated mounting plate for an automobile hanger, comprising a mounting plate, wherein a pad is provided on the mounting plate, and the pad and the mounting plate are inserted by two symmetrically arranged cylindrical nuts. The mounting plate, cylindrical nuts, and pad are all metal parts and are fixedly connected as a whole; wherein the outer dimensions of the pad are smaller than those of its corresponding hanger.

[0005] Further improvements include: the mounting plate and cylindrical nut are both made of Q235 steel, and the pad is made of galvanized steel plate.

[0006] A further improvement is that the mounting plate, cylindrical nut, and washer are fixedly connected as a whole by welding.

[0007] A further improvement is that the dimensions of the pad are 10 mm to 16 mm smaller than the corresponding lifting lug in both length and width.

[0008] A further improvement is that the thickness of the pad is 3 mm to 5 mm.

[0009] A further improvement is that when the lifting lug is installed on the powder-coated hanging plate, the length of the cylindrical nut in the corresponding bolt hole of the lifting lug is 40% to 60% of the length of the corresponding bolt hole.

[0010] A further improvement is that the aforementioned automotive hanger powder coating plate is used in electrostatic powder coating equipment.

[0011] The beneficial effects of this utility model are as follows: The use of this new powder-coated hanging plate effectively solves the problem of powder accumulation, improves the surface powder coating quality of the lifting lugs, and enhances the installation accuracy of the lifting lugs.

[0014] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0015] See Figures 1 to 7 As shown, this utility model embodiment provides a car hanger powder-coated mounting plate, including a mounting plate 1, on which a pad 3 is provided. The pad 3 and the mounting plate 1 are inserted by two symmetrically arranged cylindrical nuts 2. The mounting plate 1, cylindrical nuts 2 and pad 3 are all metal parts and are fixedly connected as a whole; wherein the outer dimensions of the pad 3 are smaller than its corresponding hanger 5. In this embodiment, the hanging plate 1, the cylindrical nut 2, and the washer 3 are all metal parts, which facilitates the conduction of the electrodes of the powder-coated parts; a washer 3 is sandwiched between the hanging plate 1 and the lifting lug 5, wherein the outer dimensions of the washer 3 are smaller than the corresponding lifting lug 5, thus forming a gap between the hanging plate 1 and the lifting lug 5. When the electrostatic powder coating equipment sprays powder onto the lifting lug 5, the gap between the hanging plate 1 and the lifting lug 5 avoids the accumulation of powder.

[0016] See Figure 1 As shown, the hanging plate 1 and the cylindrical nut 2 are both made of Q235 steel, and the pad 3 is made of galvanized steel plate. See Figure 1 As shown, the hanging plate 1, cylindrical nut 2, and pad 3 are fixedly connected as a whole by welding; In the above embodiments, the hanging plate 1, cylindrical nut 2, and washer 3 are made of steel, which facilitates the welding and processing of the parts. The welding method is simple, convenient, and low in cost.

[0017] See Figures 1 to 4 As shown, the dimensions of the pad 3 are 10 mm to 16 mm smaller than its corresponding lifting lug in both length and width; See Figure 1 As shown, the thickness of the pad 3 is 3 mm to 5 mm; In the above embodiment, the size of the gap between the hanging plate 1 and the lifting lug 5 was determined.

[0018] See Figure 3 As shown, when the lifting lug 5 is installed on the powder-coated hanging plate, the length of the cylindrical nut 2 in the corresponding bolt hole of the lifting lug 5 is 40% to 60% of the length of the corresponding bolt hole. In this embodiment, this is to facilitate the bolt 4 to be quickly screwed into the cylindrical nut 2 and to clamp the lifting lug 5. If the length of the cylindrical nut 2 in the corresponding bolt hole of the lifting lug 5 is greater than the length of the bolt hole, the bolt 4 cannot quickly clamp the lifting lug 5, and a shim of a certain thickness needs to be added.

[0019] The aforementioned automotive hanger powder coating plate is used in electrostatic powder coating equipment.

[0020] The working principle of this utility model is as follows: See Figure 3 As shown, in this utility model, a pad 3 is sandwiched between the mounting plate 1 and the hanger 5 on the automotive hanger powder coating mounting plate. The thickness of the pad 3 is 3 mm to 5 mm, and the external dimensions of the pad 3 are 10 mm to 16 mm smaller than the corresponding hanger in both length and width. Thus, a gap of 3 mm to 5 mm is formed between the mounting plate 1 and the hanger 5. When the electrostatic powder coating equipment sprays powder onto the hanger 5, the gap between the mounting plate 1 and the hanger 5 avoids the accumulation of powder, effectively solving the problem of powder accumulation, improving the surface powder coating quality of the hanger, and the installation accuracy of the hanger.

[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any simple modifications, equivalent substitutions, improvements, etc., made within the technical concept of the present utility model should be included within the protection scope of the present utility model.
