Description

Technical Field

[0001] The utility model relates to the field of wheel hub processing, in particular to a manual wheel hub drilling processing device. Background Art

[0002] The wheel hub refers to the metal part on the vehicle where the tire is mounted, also known as the wheel. It is usually made of aluminum alloy, steel and other materials, and has the function of bearing the weight of the vehicle, providing driving stability and shock absorption. The wheel hub is usually composed of spokes, rims and axles. Spokes are the parts that connect the rims and axles, and can be divided into different forms such as multi-spokes and single-spokes. The rim is the outer ring of the wheel hub, which is used to fix the tire. The axle is the part that connects the spokes and the vehicle's suspension system, allowing the wheel hub to rotate. The design and material selection of the wheel hub can affect the vehicle's handling performance, fuel economy and appearance style. Some high-performance vehicles use lightweight aluminum alloy wheels to improve the response speed of the suspension system and reduce the weight of the entire vehicle.

[0003] The rim and spokes often need to be drilled, which can reduce the weight of the entire wheel hub, thereby reducing the load and fuel consumption of the vehicle. After the rim is drilled, the structure of the rim still maintains strength. At the same time, drilling holes on the spokes can not only reduce weight, but also improve the heat dissipation effect. The mounting holes on the spoke plate on the rim are also an indispensable part. The drilling of the hub is divided into CNC machine drilling and manual drilling. Compared with manual drilling, CNC machine tools are more efficient and more programmed. However, some hubs are customized by merchants. When the machine tool does not have a corresponding milling program, it is still necessary to rely on manholes for drilling. However, when drilling manually, the stability of the hub is required to prevent the hub from shaking during drilling, causing drilling accuracy deviation and hole position movement. Manual drilling is not as accurate as lathes, so the fixation of the hub during drilling is the top priority. Whether it is machine milling or manual drilling, the waste chips generated in the drilling will affect the surrounding environment and cause safety hazards to the human body, and frequent manual cleaning will also add additional production costs. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] The technical problem to be solved by the utility model is: when drilling manually, the stability requirement of the wheel hub is high to prevent the wheel hub from shaking during drilling, resulting in drilling accuracy deviation and hole position movement. Manual drilling is not as accurate as lathe, so the fixation of the wheel hub during drilling is of paramount importance. Regardless of whether it is machine tool milling or manual drilling, the waste chips generated during drilling will affect the surrounding environment and cause safety hazards to the human body, and frequent manual cleaning will also result in additional production costs.

[0025] See also Figure 1 The cylinder supporting member 3 is L-shaped, the clamping cylinder 4 is fixed to one end of the cylinder supporting member 3, the telescopic rod of the clamping cylinder 4 penetrates the plate body of the cylinder supporting member 3 and extends to the top of the hub supporting platform 7, the cylinder supporting member 3 is used to place the clamping cylinder 4 and fix it, and the clamping cylinder 4 is fixed to the top of the hub supporting platform through the support of the cylinder supporting member 3, and the telescopic rod is controlled by the clamping cylinder 4 to extend and retract, so as to clamp the upper part of the wheel hub 10.

[0026] The clamping gasket 4a is disc-shaped and fixedly connected to one end of the telescopic rod of the clamping cylinder 4. The clamping gasket 4a is made of rubber. The clamping gasket 4a is driven by the clamping cylinder 4 and contacts the center of the wheel hub 10 to form a clamp. When the wheel hub 10 is fixed, the center hole of the wheel hub 10 is sleeved on the limiting shaft 7a, and the wheel hub supporting platform 7 is used to provide central support for it, while the main part of the wheel hub 10 is supported by the support plate assembly 5. Afterwards, the clamping gasket 4a descends to clamp the wheel hub 10, and is fixed longitudinally in the up and down directions by the wheel hub supporting platform 7 at the bottom.

[0027] There are several hollow grooves 1a, which are evenly spread toward the edge of the table top of the workbench body 1 with the hub supporting platform 7 as the center. The hollow grooves 1a are opened on the table top. When manual drilling begins, the debris generated by the drilling will fall from all around the hub supporting platform 7 and fall into the waste chip collection box 8 through the hollow grooves 1a. The waste chip collection box 8 is provided with a magnetic suction block 8a to absorb the generated metal debris.
