[0002] Metal propellers are generally made of iron, aluminum, copper or their alloys. Most existing propellers are integrally formed with 3-6 blades. The propeller blades need to be manually polished and ground during the processing. The propeller blades are mostly manually polished and ground by clamping the propeller blades' hub. There are some problems. During the polishing process, the propeller blades have fewer support points. The propeller blades may be affected by the pressure of polishing, causing slight deformation of the propeller blades, which affects the accuracy of the propeller blades. For this reason, we propose a device to prevent deformation of propeller blades during processing. Utility Model Content

The input end of the motor 41 is electrically connected to the output end of the single-chip computer 3. By placing the hub of the propeller blade inside the fixing block 43, the handle 47 is turned to drive the screw rod 44 to rotate. The rotation of the screw rod 44 drives the front clamping block 46 to move backward along the sliding column 45. The clamping block 46 clamps and fixes the hub of the propeller blade. Subsequently, the operation of the motor 41 is controlled by the single-chip computer 3 to drive the connecting shaft 42 to rotate, and the propeller blade is driven to rotate synchronously. The polished surface of the propeller blade is adjusted by the forward and reverse rotation of the motor 41.

The electric push rod 61 is fixedly connected to the lower end of the workbench 1. The telescopic rods of the electric push rod 61 are respectively slidably connected to the through holes opened on the right side of the workbench 1. The upper ends of the telescopic rods of the electric push rod 61 are provided with rotating seats 62. The rubber support blocks 63 are respectively rotatably connected to the upper ends of the rotating seats 62 through pin shafts. The operation of the electric push rod 61 and the infrared distance sensor 7 is regulated by the single-chip microcomputer 3. The infrared distance sensor 7 has a pair of infrared signal transmitters and receiving diodes. The infrared signal transmitter is used to emit a beam of infrared light, which forms a reflection process after irradiating the propeller blades. The signal is reflected to the receiving diode to receive the signal, and the time of receiving the emission and receiving is calculated. The difference data is transmitted to the single chip computer 3, and the distance of the propeller blades is calculated after being processed by the single chip computer 3.

When the rubber support block 63 contacts the surface of the propeller blade, it rotates slightly through the rotating seat 62 according to the different surfaces of the propeller blades, ensuring the supporting effect of the rubber support block 63 on the propeller blades while providing flexible protection for the propeller blades. Through the cooperation of multiple electric push rods 61 and infrared distance sensors 7, it is achieved that multiple supports are provided for the propeller blades during manual grinding, reducing the pressure on the propeller blades and avoiding the phenomenon that the propeller blades are slightly deformed due to the pressure of grinding and polishing, which affects the accuracy of the propeller blades.

[0025] The working principle of a device for preventing propeller blades from being deformed during processing provided by the utility model is as follows: by placing the hub of the propeller blade inside the fixing block 43, turning the handle 47, driving the screw rod 44 to rotate, the rotation of the screw rod 44 drives the front clamping block 46 to move backward along the sliding column 45, the clamping block 46 clamps and fixes the hub of the propeller blade, then the operation of the motor 41 is regulated by the single chip microcomputer 3 to drive the connecting shaft 42 to rotate, and synchronously drive the propeller blade to rotate, and the polished surface of the propeller blade is adjusted by the forward and reverse rotation of the motor 41, and then the operation of the electric push rod 61 and the infrared distance sensor 7 is regulated by the single chip microcomputer 3. The infrared distance sensor 7 has a pair of infrared signal transmitters and receiving diodes, and uses the infrared signal transmitter to emit a beam of infrared light, which forms a reflection process after being irradiated to the propeller blade, and is reflected to the receiving diode. The receiving diode receives the signal and transmits the data of the time difference between the transmitted and received signals to the single chip microcomputer 3. After being processed by the single chip microcomputer 3, the distance of the propeller blades is calculated. Subsequently, the single chip microcomputer 3 controls the operation of the electric push rod 61, extends the telescopic rod, and drives the rubber support block 63 to move upward. When the rubber support block 63 contacts the surface of the propeller blade, it rotates slightly through the rotating seat 62 according to the different surfaces of the propeller blades, thereby ensuring that the rubber support block 63 supports the propeller blades and provides flexible protection for the propeller blades. Through the cooperation of multiple electric push rods 61 and infrared distance sensors 7, it is achieved that multiple supports are provided for the propeller blades during manual grinding, thereby reducing the pressure on the propeller blades and avoiding the phenomenon that the propeller blades are slightly deformed due to the pressure of grinding and polishing, thereby affecting the accuracy of the propeller blades.
