Description

Technical Field

[0001] The utility model relates to the technical field of grinding machines, in particular to a floor-standing grinding machine for processing propellers. Background Art

[0002] Grinding machines are commonly used for sharpening various knives and tools. They are also used for grinding, deburring, and cleaning small parts. They primarily consist of a base, grinding wheel, motor or other power source, bracket, protective cover, and water dispenser. They can be categorized as handheld, vertical, suspended, and benchtop grinders. Grinding machines are also used in the production of propellers.

[0003] For example, a floor-standing grinding machine with the application publication number "CN103495910A" adopts a floor-standing design, which reduces vibration and improves the stability of the equipment during operation; a controller is provided to arbitrarily adjust the speed of the motor to meet the grinding requirements of tools of different materials; a dust suction device is provided to absorb the dust generated during operation, thereby improving the quality of the working environment; a water tank is provided to place and cool the cutting tools. However, when the floor-standing grinding machine is grinding the workpiece, since the workpiece is not fixed, when the grinding wheel contacts the workpiece, the workpiece will move on the working plane, resulting in an error in the processing position of the grinding machine, which reduces the working quality of the grinding machine. At the same time, the position of the grinding wheel of the floor-standing grinding machine is fixed. When the size of the workpiece to be ground is too large or too small, the grinding wheel cannot contact the workpiece, which increases the working limitations of the grinding machine.
