Description

Technical Field

[0001] This utility model relates to the field of wheel hub steel rim processing technology, and in particular to a powder spraying device for processing engineering vehicle wheel hub steel rims. Background Technology

[0002] The powder coating equipment for processing steel rims of engineering vehicles is a special equipment designed for the surface treatment of steel rims of engineering vehicle wheels. It delivers powder coating to the spray gun through a powder supply system, and achieves continuous spraying of steel rims with the help of a conveying device. It usually integrates a curing and baking unit to ensure that the coating is cured and formed, and finally provides a protective layer for the steel rim that is corrosion-resistant, wear-resistant and impact-resistant, while also meeting the requirements for appearance decoration.

[0003] During the powder coating process on steel rims, a rim flipping operation is necessary to ensure uniform and complete coating coverage on both sides. This requires pausing the powder coating system to accommodate the flipping action, causing a temporary interruption in the process. Specifically, the powder coating equipment can only restart after the rim has been flipped 180 degrees, precisely reset, and re-secured, allowing for continued powder coating of the uncoated side. This flipping and waiting period directly extends the overall time required for powder coating a single steel rim, increasing the process cycle and impacting the continuous production efficiency of the powder coating process. Utility Model Content

[0004] The purpose of this invention is to solve the problem that when performing powder spraying operations on steel rims, the powder spraying system needs to be paused to coordinate with the rotation, resulting in a phased interruption of the powder spraying process. Therefore, this invention proposes a powder spraying device for processing steel rims of engineering vehicle wheels.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a powder spraying device for processing steel rims of engineering vehicle wheels, comprising a wheel hub body and a wheel hub locator. The wheel hub body is disposed above the wheel hub locator, and a powder spraying mechanism is disposed on one side of the wheel hub locator. The powder spraying mechanism includes two sets of steel rim surface powder spraying components and steel rim edge powder spraying components. The two sets of steel rim surface powder spraying components are disposed at both ends of the steel rim edge powder spraying components. A transfer frame is fixedly connected to one side of the steel rim edge powder spraying components, and the drive end of the robotic arm is fixedly connected to the transfer frame.

[0006] Preferably, the steel ring edge powder coating assembly includes a mounting frame and several electric powder coating devices, with the several electric powder coating devices fixedly mounted on one side of the mounting frame.

[0007] Preferably, the steel ring surface powder coating assembly includes an adjustment chamber, a mounting rod, and a drive cylinder. One end of the mounting rod is slidably connected to the inside of the adjustment chamber, and another electric powder coating device is fixedly installed at the other end of the mounting rod. The drive end of the drive cylinder is fixedly connected to one side of one end of the mounting rod.

[0008] Preferably, limiting rods are fixedly connected to both sides of one end of the mounting rod, and sliding grooves are provided on both sides of the adjustment chamber, with the limiting rods slidably connected inside the sliding grooves.

[0009] Preferably, one end of the limiting rod is fixedly connected to a side plate, and the driving end of the driving cylinder is fixedly connected to the side plate.

[0010] Preferably, the adapter frame has a plurality of mounting holes symmetrically arranged inside.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, the electric powder sprayer in the steel rim powder spraying assembly simultaneously performs powder spraying on both rims of the wheel hub, eliminating the need to flip the wheel hub body to complete the full powder spraying, saving the flipping process, greatly shortening the powder spraying time of a single wheel, improving the production cycle, and increasing the overall production efficiency. In addition, the coordinated operation of multiple components can ensure uniform powder spraying in all parts of the wheel hub, avoid secondary positioning errors that may occur during the flipping process, and ensure stable and consistent powder spraying quality.

[0013] 2. In this utility model, when the steel rim powder spraying assembly sprays powder onto the rim surface of the wheel hub body, the drive cylinder drives one end of the mounting rod to slide inside the adjustment chamber, while the other end of the mounting rod drives the electric powder sprayer to extend into the wheel hub body, thereby achieving comprehensive powder spraying onto the rim surface of the wheel hub body. The drive cylinder drives the mounting rod to extend and retract flexibly, which can adapt to the internal space of wheel hub bodies with different diameters and depths, enhancing the equipment's adaptability to diverse wheel hub specifications, eliminating the need for frequent tooling changes, and reducing changeover costs.

Detailed Implementation

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figure 1 - Figure 3 As shown, this utility model provides a powder spraying device for processing steel rims of engineering vehicle wheels, including a wheel hub body 1 and a wheel hub locator 2. The wheel hub body 1 is disposed above the wheel hub locator 2. A powder spraying mechanism 3 is disposed on one side of the wheel hub locator 2. The powder spraying mechanism 3 includes two sets of steel rim surface powder spraying components 31 and steel rim edge powder spraying components 32. The two sets of steel rim surface powder spraying components 31 are disposed at both ends of the steel rim edge powder spraying components 32. A transition frame 33 is fixedly connected to one side of the steel rim edge powder spraying components 32. Several mounting holes are symmetrically opened inside the transition frame 33. The drive end of the robotic arm is fixedly connected to the transition frame 33. The steel rim edge powder spraying components 32 include a mounting frame 321 and several electric powder sprayers 322. Several electric powder sprayers 322 are fixedly installed on one side of the mounting frame 321.

[0022] The specific setup and function of this embodiment are described below. The robotic arm drive end is fixed to the adapter frame 33 by bolts and mounting holes. The robotic arm drives the powder spraying mechanism 3 to approach the edge of the wheel hub body 1. Powder is transported to the electric powder sprayer 322 through the powder supply pipe, and then sprayed onto the outside of the wheel hub body 1 by the electric powder sprayer 322. Among them, the electric powder sprayer 322 in the steel rim edge powder spraying assembly 32 is responsible for powder spraying the edge of the steel rim, while the electric powder sprayer 322 in the steel rim surface powder spraying assembly 31 simultaneously performs powder spraying operations on both rim surfaces of the wheel hub. The wheel hub body 1 can be fully powder sprayed without flipping it over, eliminating the flipping process, significantly shortening the powder spraying operation time of a single wheel, improving the production cycle, and increasing the overall production efficiency. In addition, the coordinated operation of multiple components can ensure uniform powder spraying of all parts of the wheel hub, avoid secondary positioning errors that may occur during the flipping process, and ensure stable and consistent powder spraying quality.

[0023] Example 2: Figure 1 - Figure 4 As shown, the powder coating equipment for processing steel rims of engineering vehicle wheels in this utility model includes a wheel hub body 1 and a wheel hub locator 2. The wheel hub body 1 is positioned above the wheel hub locator 2. A powder coating mechanism 3 is provided on one side of the wheel hub locator 2. The powder coating mechanism 3 includes two sets of steel rim surface powder coating components 31 and steel rim edge powder coating components 32. The two sets of steel rim surface powder coating components 31 are located at both ends of the steel rim edge powder coating components 32. A transfer frame 33 is fixedly connected to one side of the steel rim edge powder coating components 32. The drive end of the robotic arm is fixedly connected to the transfer frame 33. The steel rim edge powder coating components 32 include a mounting frame 321 and several electric powder coating nozzles 322. The several electric powder coating nozzles 322 are fixedly mounted on the mounting frame. On one side of 321, the steel ring surface powder spraying assembly 31 includes an adjustment chamber 311, an installation rod 312, and a drive cylinder 313. One end of the installation rod 312 is slidably connected to the inside of the adjustment chamber 311. Another electric powder sprayer 322 is fixedly installed on the other end of the installation rod 312. The drive end of the drive cylinder 313 is fixedly connected to one side of one end of the installation rod 312. Limiting rods 314 are fixedly connected to both sides of one end of the installation rod 312. Sliding grooves 315 are provided on both sides of the adjustment chamber 311. The limiting rods 314 are slidably connected to the inside of the sliding grooves 315. One end of the limiting rod 314 is fixedly connected to a side plate 316. The drive end of the drive cylinder 313 is fixedly connected to the side plate 316.

[0024] The overall effect of this embodiment is that when the steel rim powder spraying assembly 31 sprays powder onto the rim surface of the wheel hub body 1, the drive cylinder 313 drives one end of the mounting rod 312 to slide inside the adjustment chamber 311, while the other end of the mounting rod 312 drives the electric powder sprayer 322 to extend into the wheel hub body 1, thereby achieving full powder spraying onto the rim surface of the wheel hub body 1. The drive cylinder 313 drives the mounting rod 312 to extend and retract flexibly, which can adapt to the internal space of the wheel hub body 1 with different diameters and depths, enhancing the equipment's adaptability to diverse wheel hub specifications, eliminating the need for frequent tooling changes, and reducing changeover costs. Furthermore, when one end of the mounting rod 312 slides within the adjusting chamber 311, the limiting rod 314 slides synchronously within the sliding groove 315, thereby constraining the movement trajectory of the mounting rod 312 and ensuring that the mounting rod 312 can slide vertically up and down. The cooperation between the limiting rod 314 and the sliding groove 315 strictly limits the movement trajectory of the mounting rod 312, preventing the electric powder sprayer 322 from deviating due to mechanical shaking, ensuring that the powder spraying path is accurate and controllable, reducing local missed spraying and double spraying, and further improving the integrity of the powder spraying coverage.

[0025] The device's operation and working principle are as follows: The robotic arm drive end is fixed to the adapter frame 33 via bolts and mounting holes. The robotic arm drives the powder spraying mechanism 3 to approach the edge of the wheel hub body 1. Powder is transported to the electric powder sprayer 322 via a powder supply pipe, and then sprayed onto the outside of the wheel hub body 1 by the electric powder sprayer 322. Specifically, the electric powder sprayer 322 in the steel rim edge powder spraying assembly 32 is responsible for powder spraying the steel rim edge, while the electric powder sprayer 322 in the steel rim surface powder spraying assembly 31 simultaneously performs powder spraying operations on both rim surfaces of the wheel hub, completing the full powder spraying without flipping the wheel hub body 1.

[0026] When the steel rim powder spraying assembly 31 sprays powder onto the rim surface of the wheel hub body 1, the drive cylinder 313 drives one end of the mounting rod 312 to slide inside the adjustment chamber 311, while the other end of the mounting rod 312 drives the electric powder sprayer 322 to extend into the wheel hub body 1, thereby achieving full powder spraying onto the rim surface of the wheel hub body 1.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
