Description

Technical Field

[0001] This utility model relates to the field of wheel hub after-treatment equipment, and in particular to a deburring device and equipment for painted wheel hubs. Background Technology

[0002] There are three methods for manufacturing automobile wheel hubs: gravity casting, forging, and low-pressure precision casting. Forging involves directly extruding a whole aluminum ingot into a mold using a thousand-ton press. Its advantages include uniform density, a smooth and fine surface, thin wheel hub walls, light weight, and the highest material strength. However, it has a low yield and high manufacturing cost. Low-pressure precision casting involves precision casting under low pressure. This casting method has good formability, clear contours, uniform density, and a smooth surface, but it also suffers from high equipment costs and low production efficiency. Gravity casting uses gravity to pour molten aluminum alloy into a mold. After forming, it is processed and polished on a lathe to complete production. The manufacturing process is relatively simple, requiring no precise casting technology, and has low cost and high production efficiency. This method is currently widely used in the production of aluminum alloy wheel hubs. However, in actual production, it has been found that this method easily produces sand holes on the wheel hub surface, insufficient surface smoothness, burrs, and a stinging sensation when touched by fingers. Therefore, there is an urgent need to provide a deburring device and equipment for painted wheel hubs to solve the above problems. Summary of the Invention

[0003] Therefore, there is a need for an easy-to-operate, automated deburring device and equipment for painted wheel hubs.

[0004] To achieve the above objectives, the inventors provide a deburring device for painted wheel hubs, comprising: a mounting base and a scraper assembly, wherein a pair of side plates are provided on the lower surface of the mounting base, and a pin is rotatably provided between the side plates; The scraper assembly includes a rotating sleeve, which is rotatably mounted between two side plates via a pin. A limiting plate and a downward-facing scraper are fixedly mounted on the rotating sleeve. A limiting buffer mechanism is also provided on the lower surface of the mounting base. One end of the limiting buffer mechanism is connected to the mounting base, and the other end is connected to or abuts against the limiting plate.

[0006] As a preferred structure of this utility model, the limiting buffer mechanism includes a floating cylinder and / or a buffer spring. The fixed end of the floating cylinder is connected to the mounting base, and the telescopic end of the floating cylinder abuts against the first limiting plate and / or the second limiting plate. One end of the buffer spring is connected to the mounting base, and the other end is connected to the second limiting plate and / or the first limiting plate.

[0007] As a preferred structure of this utility model, the mounting base, the second limiting plate and / or the first limiting plate connected to the buffer spring are provided with threaded holes, and an adjusting rod is provided in the threaded holes. The two ends of the buffer spring are respectively connected to the adjusting rod.

[0008] As a preferred structure of this utility model, the included angle between the first limiting plate and the second limiting plate is 180 degrees.

[0009] As a preferred structure of this utility model, the limiting buffer mechanism further includes a limiting rod, which is disposed between the mounting base and the limiting plate in the backward direction of the scraper, and the top end of the limiting rod is fixedly connected to the mounting base.

[0010] As a preferred structure of this utility model, the scraper is a rhomboid scraper.

[0011] As a preferred structure of this utility model, a displacement sensor is provided on the mounting base or side plate, with the detection end of the displacement sensor facing downward.

[0012] As a preferred structure of this utility model, it also includes a purging device, wherein the nozzle of the purging device is connected to the mounting base or side plate.

[0013] To achieve the above objectives, the inventors provide a deburring device for painted wheel hubs, including a robotic arm and a deburring device for painted wheel hubs as described in any one of the above inventions, wherein the mounting base is connected to the operating end of the robotic arm via a flange.

[0014] Unlike existing technologies, the above technical solution achieves the following beneficial effects: This device and equipment uses a scraper to deburr, scrape edges, and chamfer corners on wheel hubs. It can be mounted on a robotic arm for automated operation, effectively removing sand holes and burrs from wheel hubs, improving their smoothness and quality. Furthermore, the device and equipment include a limiting and buffering mechanism. This mechanism effectively protects the scraper during deburring, preventing hard contact between the scraper and the wheel hub surface that could damage both, thus extending the scraper's lifespan and increasing the wheel hub's yield rate.

[0017] To explain in detail the technical content, structural features, objectives, and effects of the technical solution, the following description is provided in conjunction with specific embodiments and accompanying drawings.

[0018] like Figure 1 and Figure 2 As shown, this embodiment provides a deburring device for painted wheel hubs, including: a mounting base 101 and a scraper 105 assembly. The lower surface of the mounting base 101 is provided with a pair of side plates 102, and a pin 103 is rotatably provided between the side plates 102. The scraper 105 assembly includes a rotating sleeve 104, which is rotatably disposed between two side plates 102 via a pin 103. A limiting plate and a downward-facing scraper 105 are fixedly mounted on the rotating sleeve 104. A limiting buffer mechanism is also provided on the lower surface of the mounting base 101. One end of the limiting buffer mechanism is connected to the mounting base 101, and the other end is connected to or abuts against the limiting plate.

[0019] In the specific implementation of this embodiment, the scraper 105 is a diamond-shaped scraper 105. The limiting plate includes a first limiting plate 106 located in the forward direction of the scraper 105 and a second limiting plate 107 located in the backward direction of the scraper 105. The first limiting plate 106 and the second limiting plate 107 are respectively provided with limiting buffer mechanisms. The first limiting plate 106 and the second limiting plate 107 are horizontally arranged, that is, the included angle between the first limiting plate 106 and the second limiting plate 107 is set to 180 degrees. The limiting buffer mechanism includes a floating cylinder 108 and a buffer spring 109. The floating cylinder 108 is located between the first limiting plate 106 in the forward direction of the scraper 105 and the mounting base 101, that is, the fixed end of the floating cylinder 108 is fixedly connected to the lower surface of the mounting base 101, and the telescopic end of the floating cylinder 108 abuts against the first limiting plate 106. The buffer spring 109 is located between the second limiting plate 107 and the mounting base 101 in the retraction direction of the scraper 105. One end of the buffer spring 109 is connected to the mounting base 101, and the other end is connected to the second limiting plate 107. Alternatively, threaded holes can be provided on both the mounting base 101 and the second limiting plate 107, with an adjustable adjusting rod 110 installed within each hole. Both ends of the buffer spring 109 are connected to the adjusting rod 110, facilitating adjustment of the preload of the buffer spring 109.

[0020] Of course, in different embodiments, the limiting buffer mechanism can always use a floating cylinder 108 or a buffer spring 109. In the above embodiments, the limiting buffer mechanism can effectively protect the scraper 105 from hard contact with the wheel hub, preventing the scraper 105 from breaking or being damaged, while also protecting the wheel hub.

[0021] In some embodiments, such as Figure 3 and Figure 4 As shown, to prevent the scraper 105 from overturning beyond its limit under force during the deburring process, in this embodiment, the limiting and buffering mechanism further includes a limiting rod 111. The limiting rod 111 is located between the mounting base 101 and the limiting plate in the backward direction of the scraper 105, and the top end of the limiting rod 111 is fixedly connected to the mounting base 101. That is, the backward tilting angle of the scraper 105 is limited by the limiting rod 111.

[0022] like Figure 3 and Figure 4 As shown, in some embodiments, a displacement sensor 112 can be provided on the mounting base 101 or side plate 102, with the detection end of the displacement sensor 112 facing downwards; this enables the detection of the wheel hub position. A blowing device can also be provided, with its nozzle 113 connected to the mounting base 101 or side plate 102. The nozzle 113 can be externally connected to an air pump. This blows away scraped debris to prevent it from affecting subsequent processing by the scraper 105.

[0023] In some embodiments, a deburring device for painted wheel hubs is also provided, including a robotic arm (not shown in the figure) and a deburring device for painted wheel hubs as described in any of the above embodiments. The mounting base 101 is connected to the operating end of the robotic arm via a flange 201. In the specific implementation of this embodiment, the robotic arm can drive the deburring device for painted wheel hubs to perform operations such as deburring and chamfering on the wheel hubs. The entire operation process can be automated and intelligent, greatly improving processing efficiency and yield.

[0024] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of patent protection for this utility model.
