Description

Technical Field

[0001] This utility model is a painting suspension device, belonging to the field of automotive parts processing. Background Technology

[0002] In the automotive parts manufacturing system, painting is a key process for improving the corrosion resistance and aesthetics of parts. To achieve automated and continuous painting, the industry commonly adopts an I-beam suspension conveyor system. Multiple suspension structures can roll along the I-beam, and the automotive parts to be painted are suspended on these structures. As the suspension structures move along the I-beam, the parts can pass through different painting stations in sequence, completing a uniform and comprehensive coating treatment. This mode is widely used in automotive parts painting production lines due to its high-efficiency conveying and suitability for assembly line operations.

[0003] The core components of this type of suspension structure include a U-shaped frame and rollers installed at both ends. The rollers and the I-beam have a rolling connection, ensuring smooth movement of the entire structure. When a component on a certain suspension structure needs to be disassembled and replaced due to impact, aging, or other reasons, the U-shaped frame's structure restricts its removal from the I-beam in the middle of the production line. Instead, the U-shaped frame must be pushed towards the end of the I-beam. During this pushing process, multiple undamaged suspension structures between the U-shaped frame and the end of the I-beam need to move synchronously to create a passage, extending the replacement and maintenance time for a single component and resulting in low overall production line maintenance efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hanging device for spraying paint to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a paint spraying suspension device, comprising:

[0006] The guide beam has an "I" shaped cross-section, and the two sides of the guide beam form a "U" shaped track groove.

[0007] The suspension components are provided in multiple sets. Each suspension component includes two rollers. The two rollers in each set of the suspension components are respectively rotatably mounted in two track grooves on the guide beam. A hanging plate is rotatably connected to one side of each roller. The lower side of the hanging plate has two interconnected bent parts. The upper bent part is connected and fixed to the hanging plate, and the lower end of the lower bent part is equipped with a hanging lug. The two aligned bent parts are connected by fasteners formed by long screws and nuts.

[0008] Furthermore, a connecting part is provided between the two bends on the lower side of the hanging plate, and the connecting part is connected and fixed to the two bends.

[0009] Furthermore, a support rod is installed on the connecting part, and a ring for connecting the chain is installed on the end of the support rod away from the connecting part.

[0010] Furthermore, the connecting part and the bending part are integrally formed, and the bending part, the hanging ear, and the hanging plate are integrally formed.

[0011] Furthermore, the cross-section of the bent portion is U-shaped, and horizontal holes are provided on both sides of the two opposite bent portions. One end of the long screw passes through the channel formed by the two horizontal holes and is threaded to connect to the nut.

[0012] Furthermore, a shaft head is installed at the upper end of the hanging plate, and a rolling bearing is installed at the end of the shaft head away from the hanging plate, and the rolling bearing is installed inside a roller.

[0013] Furthermore, the roller has an annular groove on the side facing the hanging plate, and a shielding sleeve is provided between the roller and the hanging plate. The shielding sleeve is connected to the hanging plate through a connector, and the shielding sleeve is fitted on the shaft head. The end of the shielding sleeve away from the hanging plate is inserted into the annular groove.

[0014] Furthermore, two symmetrically arranged hollow columns are installed on the side of the shielding sleeve away from the roller. The hollow columns are provided with connecting ears on the side away from the shielding sleeve. The connecting ears are connected and fixed to the hanging plate. The connecting ears are connected to the hollow columns by screws.

[0015] The beneficial effects of this utility model are:

[0016] The suspension system consists of two sets of symmetrical hanging plates and bending sections. The mating bending sections are fastened with long screws and nuts. When a set of suspension components needs to be repaired or replaced, simply loosen the long screws and nuts to disconnect the two bending sections. The damaged suspension component can then be removed from the track groove of the guide beam on one side without having to move other undamaged suspension components. This solves the problem of traditional U-shaped frame structures requiring them to be moved to the end for disassembly, shortens maintenance time, and improves the overall operation and maintenance efficiency of the production line.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] Please see Figures 1-4 This utility model provides a technical solution: a paint spraying suspension device, including a guide beam 1 with an "I" shaped cross section, and two sides of the guide beam 1 forming a track groove with a "U" shaped cross section. Multiple sets of suspension components are provided, and each suspension component includes two rollers 2. The two rollers 2 in one set of suspension components are respectively rolled in the two track grooves on the guide beam 1, so that the suspension component moves along the guide beam 1.

[0031] A hanging plate 3 is rotatably connected to one side of the roller 2. A shaft head 21 is installed on the upper end of the hanging plate 3. A rolling bearing 23 is installed on the end of the shaft head 21 away from the hanging plate 3. The rolling bearing 23 is installed inside the roller 2. An annular groove 22 is opened on the side of the roller 2 facing the hanging plate 3. A shielding sleeve 6 is provided between the roller 2 and the hanging plate 3. Two symmetrically arranged hollow columns 61 are installed on the side of the shielding sleeve 6 away from the roller 2. A connecting ear 62 is provided on the side of the hollow column 61 away from the shielding sleeve 6. The connecting ear 62 is connected and fixed to the hanging plate 3. The connecting ear 62 is connected to the hollow column 61 by screws 63, completing the assembly of the shielding sleeve 6 and the hanging plate 3. The shielding sleeve 6 is sleeved on the shaft head 21. The end of the shielding sleeve 6 away from the hanging plate 3 is inserted into the annular groove 22. Thus, the shielding sleeve 6 and the hanging plate 3 work together to shield the rolling bearing 23 without affecting the rolling of the roller 2, preventing paint from adhering to the inner wall of the rolling bearing 23.

[0032] The lower side of the hanging plate 3 is provided with two interconnected bends 31. A connecting part 32 is provided between the two bends 31 on the lower side of the hanging plate 3. The connecting part 32 is connected and fixed to the two bends 31. A support rod 51 is installed on the connecting part 32. A ring 5 for connecting the chain is installed at the end of the support rod 51 away from the connecting part 32. The ring 5 is connected to the chain driven by the motor. When the motor drives the chain to rotate, the roller 2 can move along the guide beam 1.

[0033] See Figures 1-4 The upper bending part 31 is connected and fixed to the hanging plate 3. The lower end of the lower bending part 31 is equipped with a hanging ear 33. The connecting part 32 and the bending part 31 are integrally formed. The bending part 31, the hanging ear 33, and the hanging plate 3 are integrally formed. The cross-section of the bending part 31 is "U" shaped. The two opposite bending parts 31 are provided with horizontal holes 34 on their back sides. One end of the long screw 4 passes through the channel formed by the two horizontal holes 34 and is threaded to the nut 41. The suspension component consists of two symmetrical sets of hanging plates 3 and bending parts 31. The mating bending parts 31 are fastened with long screws 4 and nuts 41. When a set of suspension components needs to be repaired or replaced, simply loosen the long screws 4 and nuts 41 to disconnect the connection between the two bending parts 31. The damaged suspension component can then be removed from the track groove of the guide beam 1 on one side without having to move other undamaged suspension components. This solves the drawback of traditional U-shaped frame structures that require moving to the end for disassembly, shortens maintenance time, and improves the overall operation and maintenance efficiency of the production line. After maintenance, the rollers 2 in the repaired suspension component can be directly inserted into the track groove, and the bending parts 31 can be reconnected with long screws 4 and nuts 41 to quickly restore the use of the suspension component. This avoids the entire painting conveyor line from being stopped due to the maintenance of a single set of suspension components, ensuring production continuity.

[0034] A space is formed between the two opposing bends 31. At this time, part of the long screw 4 is exposed. When the long screw 4 cannot be separated from the nut 41 smoothly due to paint adhesion, the long screw 4 can be cut off by using the space between the two opposing bends 31.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
