Technical Field

[0001] The utility model relates to the technical field of grinding machines, in particular to a hand-propelled grinding machine. Background Art

[0002] A grinding machine is a mechanical device mainly used for grinding and cutting metal and non-metal materials. The grinding machine uses a high-speed rotating abrasive wheel as a tool to grind, cut, polish and other processing processes on the workpiece. Grinding machines are widely used in many industries, such as automobile manufacturing, steel smelting, shipbuilding and aerospace. The main components of a grinding machine include a base, a grinding wheel, a motor or other power source, a bracket protection device and a water feeder. According to different application scenarios, grinding machines can be divided into various types such as handheld, vertical, county-mounted and desktop.

[0003] When the existing hand-propelled grinder is in operation, due to its heavy size and the different heights of products, the workers have to hold the grinder up and down, which is extremely physically demanding. The workers also have to hold the grinder for a long time and it is difficult for them to hold it for a long time. They need to stop working and rest before continuing to work, which reduces work efficiency and affects the grinding effect of the grinding wheel.

[0004] For this reason, a hand-push grinding wheel machine is proposed. Utility Model Content

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. The utility model can move the device to a designated location through a moving assembly. After arriving at the designated location, the movable box is driven to move upward or downward by the lifting assembly until the outer grinding wheel on the front side of the movable box corresponds to the position of the product, the external controller is started, and the servo motor is started to drive the first rotating shaft to rotate through the output.
