Description

Technical Field

[0001] This utility model relates to the field of propeller technology, and in particular to a grinding device for manufacturing marine propellers. Background Technology

[0002] A propeller is a device that converts engine power into propulsion by rotating its blades in air or water. It typically has two or more blades connected to a hub, with the rearward-facing surface of the blades forming a helical or near-helical plane. Propellers come in many types and have a wide range of applications, such as in aircraft and ship propulsion. During manufacturing, propellers require grinding and polishing to reduce frictional resistance between the blades and the air or water.

[0003] Chinese patent application CN201711090838.4 discloses a grinding device for propeller processing, relating to the field of propeller processing technology. This grinding device includes a base with feet fixedly installed at its bottom. The top of the base is welded to the bottom of an electric telescopic rod, which is also welded to the bottom of a top plate. A top motor is fixedly mounted on the bottom of the top plate via a mounting bracket. The output shaft of the top motor is fixedly connected to the top of a grinding disc, and a screw cylinder is provided at the bottom of the grinding disc. After the propeller is fixed, the extension and retraction of the electric telescopic rod causes the rotating grinding disc to move closer to or away from the propeller, achieving grinding and polishing. Simultaneously, the extension and retraction of the electro-hydraulic actuator drives the bottom motor to move left and right. When the bottom motor rotates, it rotates the fixed propeller, changing the contact position between the grinding disc and the propeller, allowing the entire top of the propeller to be ground and polished. The operation is simple and quick, effectively improving grinding efficiency.
