Description

Technical Field

[0001] The utility model belongs to the technical field of sandblasting devices, and more specifically, particularly relates to a sandblasting device for wheel hub processing. Background Art

[0002] When making automobile aluminum alloy wheels, in order to protect their surfaces, they need to be painted. In order to make the paint adhere better to the surface of the automobile aluminum alloy wheels, sandblasting is required before painting to improve the surface quality of the automobile aluminum alloy wheels and prevent the wheels from being oxidized during long-term use of the automobile. Currently, most of the main methods used are manual spraying using sandblasting devices.

[0003] The existing publication number CN213970685U discloses a sandblasting device for automobile wheel hub processing. Although a sand hole is opened through the bottom surface of the device cover, and the sand hole and the tail end of the sandblasting tube are vertically penetrated, the sandblasting tube introduces a well-proportioned sand liquid into the sand hole, and the sand liquid is evenly sprayed on the wheel hub through the fine sand hole, which solves the problem that the sandblasting device is uneven in sandblasting the wheel hub. A sand leakage hole is opened through the bottom of the processing groove, and the wire groove can store the excess sandblasting tube inside the wire groove, which solves the problem that the sandblasting tube is easily damaged during a long period of processing and causes sand liquid leakage.

[0004] Based on the above, the inventors have discovered the following problems: However, when the device is sandblasting the automobile wheel hub, the wheel hub is in a stationary state, and when the wheel hub is in a stationary state, it needs to be supported by an object. If it is supported, some parts of the wheel hub will be difficult to sandblast, resulting in incomplete sandblasting of the wheel hub. At the same time, more sand will remain on the top of the support, resulting in a lower sand utilization rate during sandblasting.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a sandblasting device for wheel hub processing is provided, in order to achieve a more practical purpose. Utility Model Content
