Description
Technical Field
[0001] The utility model relates to the technical field of grinding, in particular to a grinding machine for automobile repair with adjustable grinding angle. Background Art
[0002] Auto repair grinders can be roughly divided into two types according to how they are used. One is handheld grinding of cars, or the other is fixed and then the auto parts are taken over for grinding. This mainly depends on the specific grinding needs and working environment. Handheld grinders are usually used for small-area or fine grinding of car surfaces. Operators can hold the grinder and flexibly adjust the grinding angle and strength as needed. This method is suitable for repairing small defects, removing scratches or performing local polishing. On the other hand, if large-area grinding work or overall processing of auto parts is required, a fixed grinder can be used. This grinder can be fixed in an appropriate position , and then the operator places the auto parts on the workbench of the grinder for grinding. This method can ensure the stability and accuracy of grinding and improve work efficiency. However, when using traditional fixed auto repair grinders, simple clamps or manual fixation methods are often used. This method is often not ideal for auto parts with complex shapes or variable sizes, and the workpiece is prone to shaking or falling off. Moreover, traditional grinders often have fixed grinding angles or limited adjustment ranges, which makes it very difficult to grind some special angles or curved surfaces. The limited grinding angle will cause some areas to be unable to be effectively polished, thus affecting the quality of repair. Utility Model Content
