[0004] To improve the working efficiency of the equipment, the surface shape of the above-mentioned fan blades is usually designed as a complex shape of a twisted variable cross-section curved surface, and high processing accuracy of the fan blades is required. The fan blades need to be processed by cutting and grinding. However, at present, most of them still rely on manual operations, with low efficiency, poor quality and consistency of the fan blades, and easy to cause worker injuries. Summary of the Invention

[0005] The main technical problem to be solved by the present invention is to provide a processing equipment for automatically cutting and grinding fans, so as to improve the processing accuracy and production efficiency of fans.

[0006] To solve the above technical problem, the technical solution adopted by the present invention is: an automatic fan processing equipment, including a frame body and a material transport vehicle for placing fans. Inside the frame body, there are a loading station for the material transport vehicle to enter, an unloading station for the material transport vehicle to enter, and a processing station for processing fans.

[0007] The beneficial effects of the present invention are as follows: By setting a loading station and an unloading station inside the frame body, it is convenient for the material transport vehicle for placing fans to enter and exit, which is beneficial for the fan to enter and exit the equipment. Through the fixed device, the material transport vehicle is fixedly connected to the frame body to prevent the movement of the material transport vehicle and improve the stability of fan loading and unloading. By setting a cutting and grinding machine and a universal robotic arm at the processing station inside the frame body, the fan on the loading station is clamped by the universal robotic arm, processed by cutting and grinding by the cutting and grinding machine, and then the processed fan is placed into the unloading station by the universal robotic arm. The entire processing process has a high degree of automation, replaces manual operations, greatly improves the processing quality and efficiency of fans, and is convenient for operation by transporting fans through the material transport vehicle.

[0008] Preferably, the fixing device includes a cylinder capable of rotating and pushing the cylinder shaft. The cylinder is fixedly installed on the frame body. One end of the cylinder shaft away from the cylinder is connected with a rotating plate. A clamping plate is arranged on the material transport vehicle. When the cylinder acts, one end of the rotating plate can clamp the clamping plate. By adopting the above structure, during use, the cylinder shaft of the cylinder drives the rotating plate to rotate. When the cylinder shaft retracts, one end of the rotating plate can clamp the clamping plate on the material transport vehicle. The structure connection is stable, making the fixation of the material transport vehicle and the frame body reliable and preventing the movement of the material transport vehicle.

[0009] Preferably, an adjusting part for adjusting the rotation radius of the rotating plate is arranged between the rotating plate and the cylinder shaft. The adjusting part includes a waist-shaped hole arranged on the rotating plate. A screw is inserted into the waist-shaped hole. The rotating plate is connected with the cylinder shaft through the screw.
