Description

Technical Field

[0001] The utility model relates to the technical field of angle grinders, in particular to a vertical angle grinder. Background Art

[0002] When grinding welds, the traditional practice is for workers to use handheld grinding equipment to grind welds. This method has low grinding quality, poor consistency, and low efficiency. At the same time, it has high requirements for the physical strength and grinding skills of the grinding workers. Especially when it is necessary to grind the corner welds to R angles or right angles, manual grinding can only rely on the experience of the workers. It is difficult to grind to the standard R angle or right angle, and the quality is difficult to guarantee. Grinding welds through mechanically driven grinding mechanisms can improve efficiency, but when the grinding belt is mounted on two parallel pendulum wheels and the belt drive wheel, the swinging of the grinding head left and right will cause the position of the belt to shift slightly, causing unreasonable movement of the entire mechanism, and it is also difficult to guarantee the grinding quality.
