Description

Technical Field

[0001] This utility model relates to the field of suspension spring powder coating technology, specifically to a suspension spring anti-corrosion powder coating device. Background Technology

[0002] Powder coating is a surface treatment method in which plastic powder is sprayed onto parts. Powder coating, also known as electrostatic powder coating, is a decorative technique for metal surface treatment that has been widely adopted internationally since the 1980s.

[0003] In the prior art, one type of automotive suspension spring requires a powder coating process to achieve a corrosion-resistant effect. However, currently, the powder coating is applied from the outside of the spring towards the inside, which results in the coating on the outside of the spring being thicker than the coating on the inside. Sometimes, the coating on the inside of the spring is also missing, leading to uneven powder coating. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a suspension spring anti-corrosion powder coating device, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a suspension spring anti-corrosion powder coating device, comprising a worktable, an inner support chuck, a drive motor, a spring to be processed, a lifting mechanism, a support plate, a raw material box, two sets of connecting rods, and spray nozzles. The bottom of the inner support chuck is rotatably mounted on the worktable. The drive motor is mounted on the bottom of the worktable and connected to the rotating shaft of the inner support chuck. The inner support chuck is used to internally support and fix the spring. The lifting mechanism is used to drive the support plate to rise and fall. The two sets of connecting rods are vertically mounted on the support plate. Each connecting rod has a spray nozzle at its bottom end. The spray nozzles are connected to the raw material box through conduits. The two sets of spray nozzles correspond to the inner and outer sides of the spring, respectively.

[0006] Preferably, the support plate is further provided with a spacing adjustment mechanism for adjusting the spacing between the two sets of connecting rods.

[0007] Preferably, the spacing adjustment mechanism includes a gear, a rack one, a rack two, and an electric push rod. The gear is pivotally connected to a support plate, and two sets of guide rails are arranged laterally on the support plate. The rack one and rack two are respectively slidably adapted to the guide rails by sliders. The rack one and rack two are respectively meshed on the upper and lower sides of the gear and are respectively connected to two sets of connecting rods. The electric push rod is arranged laterally on the support plate and is connected to the rack one or rack two.

[0008] Preferably, the lifting mechanism includes a lead screw, a slide rod, a lifting block, and a lifting motor. The lead screw and slide rod are vertically arranged on the worktable. The lifting block is provided with a threaded hole for threaded connection with the lead screw and a sliding hole for sliding sleeve with the slide rod. The lifting motor is located at the bottom of the worktable and is connected to the lead screw.

[0009] Preferably, the inner support chuck is an SMW-AUTOBLOK fixed centering and vibration damping inner support chuck.

[0010] This utility model provides a suspension spring anti-corrosion powder coating device. It has the following beneficial effects: This suspension spring anti-corrosion powder coating device uses two sets of nozzles to spray from the inner and outer sides of the spring respectively. Driven by the lifting mechanism, the nozzles move along the length of the spring to spray the spring 360° without dead angles, reducing the phenomenon of coating defects and making the powder coating uniform.

[0013] This utility model embodiment provides a suspension spring anti-corrosion powder coating device, such as Figure 1-3 As shown, it includes a worktable 1, an inner support chuck 2, a drive motor 3, a spring to be processed 4, a lifting mechanism 5, a support plate 6, a raw material box 9, two sets of connecting rods 7, and a nozzle 8.

[0014] The inner support chuck 2 is used to internally support and fix the spring 4. A rotating shaft is located at the bottom of the inner support chuck 2, and the shaft is rotatably mounted on the worktable 1 via bearings. The inner support chuck 2 is a commercially available product; the model can be the German brand SMW-AUTOBLOK fixed centering and vibration-damping inner support chuck. Improvements can be made to this inner support chuck, such as welding a smaller diameter rod to the jaws. Using the rod to internally support the spring 4 reduces the contact area between the rod and the spring 4, thus increasing the coating coverage on the inner side of the spring 4. The drive motor 3 is located at the bottom of the worktable 1 and connected to the rotating shaft of the inner support chuck 2. The drive motor 3 drives the inner support chuck 2 and the spring 4 fixed on the jaws to rotate, thereby ensuring that all surfaces of the spring 4 are coated.

[0015] like Figure 1 As shown, the lifting mechanism 5 drives the support plate 6 to rise and fall. The lifting mechanism 5 includes a lead screw 51, a slide rod 52, a lifting block 53, and a lifting motor 54. The lead screw 51 and the slide rod 52 are vertically arranged on the worktable 1. The bottom end of the lead screw 51 is pivotally connected to the worktable 1 via a bearing, and the slide rod 52 is fixed to the worktable 1. The lifting block 53 has a threaded hole for threaded connection with the lead screw 51 and a sliding hole for slidingly fitting with the slide rod 52. The lifting motor 54 is located at the bottom of the worktable 1 and connected to the lead screw 51. When the lead screw 51 rotates, it drives the lifting block 53 to rise and fall, thereby realizing the raising and lowering of the nozzle 8.

[0016] like Figure 1 and Figure 2 As shown, two sets of connecting rods 7 are vertically mounted on the support plate 6. The length of the connecting rod 7 is longer than the length of the spring 4. A nozzle 8 is mounted at the bottom of each connecting rod 7, and the two nozzles 8 correspond to each other. The nozzles 8 are connected to the raw material box 9 through the conduit 16. The raw material box 9 can be mounted on the support plate 6. A pump is installed between the outlet end of the raw material box 9 and the conduit 16 to provide power for the output of the nozzles 8. The two sets of nozzles 8 correspond to the inner and outer sides of the spring 4, respectively.

[0017] By setting two sets of nozzles 8, the two sets of nozzles 8 spray from opposite sides of the inner and outer sides of the spring 4 respectively, and move along the length of the spring 4 under the drive of the lifting mechanism 5, so as to spray the spring 4 with 360° no dead angle, reduce the phenomenon of coating defects, and make the powder coating uniform.

[0018] like Figure 1 As shown, the support plate 6 is also equipped with a spacing adjustment mechanism for adjusting the distance between the two sets of connecting rods 7. By adjusting the width of the two sets of connecting rods 7, the distance between the two sets of nozzles 8 can be adjusted according to the model of the spring 4, making it highly versatile and adaptable.

[0019] Specifically, such as Figure 2As shown, the spacing adjustment mechanism includes a gear 10, a rack 11, a rack 12, and an electric push rod 13. The gear 10 is pivotally connected to the support plate 6. Two sets of guide rails 14 are arranged laterally on the support plate 6. The racks 11 and 12 are slidably fitted onto the guide rails 14 via sliders 15. The guide rails 14 guide the lateral sliding of the racks 11 and 12. The racks 11 and 12 mesh with the upper and lower sides of the gear 10, respectively, and are connected to two sets of connecting rods 7. The electric push rod 13 is arranged laterally on the support plate 6 and is connected to either the rack 11 or the rack 12. By pushing one rack with the electric push rod 13, the other rack can be moved in conjunction with the gear 10, causing the rack 11 or the rack 12 to move in different lateral directions, thereby achieving the spacing adjustment between the two nozzles 8.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
