Description

Technical Field

[0001] This utility model relates to a handheld wheel hub drilling device, belonging to the field of automotive repair and modification technology, and particularly to a wheel hub drilling device. Background Technology

[0002] With the development of automotive culture, the car modification market is booming. Car owners are increasingly demanding personalized wheel customization to enhance vehicle performance and appearance. Different modification schemes often require drilling specific numbers, positions, and sizes of holes in the wheel rims to accommodate different braking and suspension systems or achieve unique exterior designs. During vehicle use, wheel rims may be damaged for various reasons, requiring repair or replacement. Sometimes, drilling may be necessary to match new parts. After-sales repairs are usually performed on-site, requiring portable drilling equipment that can be quickly deployed in various working environments. Handheld wheel rim drills perfectly meet this need. Traditional wheel rim drilling methods cannot satisfy such personalized and diverse demands; therefore, a flexible and precise handheld device is needed.

[0003] A handheld wheel hub drilling device (publication number: CN207615689U) is disclosed. This invention provides a handheld drilling device for processing aluminum alloy wheel hubs, including a worktable. A first support rod and a second support rod are fixedly connected to the left and right sides of the top of the worktable, respectively. Both the first and second support rods have through holes on their sides. A sliding rod is fixedly connected between the top and bottom of the inner wall of each through hole. A slider is movably connected to the surface of the sliding rod, and a mounting plate is fixedly connected between the two sliders. A shock-absorbing block is sleeved on the surface of the mounting plate, and a motor is fixedly connected to the bottom of the shock-absorbing block. A rotating shaft is fixedly connected to the output end of the motor. This invention, by setting up a sliding rod and slider, allows the user to hold the handle and move it, causing the slider to slide and move on the sliding rod. This adjusts the height position during aluminum alloy wheel hub processing and facilitates drilling, enhancing the practicality of this grinding device used for steel structure processing.

[0004] While the existing devices described above are simple to operate and can make holes, they are not portable. The complex design of the workbench and support rods makes it difficult to carry the drilling device easily and move it to service scenarios. In addition, the maintenance costs are high. If a single part is damaged, it is difficult to replace the individual part, which increases the maintenance cost. Furthermore, it is not possible to quickly replace or assemble parts, which increases downtime and parts replacement time. Utility Model Content
