Technical Field

[0002] A fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. The main structural components of the fan are the fan blade, the casing, the air inlet, the bracket, the motor, the pulley, the coupling, the silencer, the transmission parts, etc. Currently, during the manufacturing process of the fan blade, its surface needs to be polished to avoid the uneven surface of the fan blade from reducing the quality of the fan blade. When polishing the fan blade, it is necessary to timely clean the waste generated during polishing to prevent the waste from accumulating inside the polishing device and reducing the working efficiency of the device. Therefore, we propose an efficient anti-blocking polishing device for a fan blade. Summary of the Invention

One end of the elastic rod away from the baffle is fixedly connected to the cylindrical block. An inclined groove is formed on the surface of the cylindrical block.

By elastically squeezing the end of the fan blade through the two elastic rods, the fan blade can be positioned inside the clamping frame. The protective pad is fixedly connected to the inner wall of the inclined groove; The elastic rod passes through the clamping frame and extends to the inside of the clamping frame.

[0008] Further, a positioning frame is fixedly connected to the inner wall of the support. A water tank is fixedly connected to the bottom of the inner wall of the positioning frame. An extrusion rod is fixedly connected to the surface of the rotating rod. A positioning hole is formed at the top of the positioning frame.

The bottom of the bent pipe is movably connected with a plug pad through a rotating shaft. A positioning frame is arranged inside the bracket. One end of the inclined plane block close to the rotating rod is provided with an inclined plane, so that the extrusion rod can push the connecting rod to move through the inclined plane of the inclined plane block. Three air cylinder rods are arranged on the surface of the positioning frame, which is convenient for cleaning dust by the gas inside the air cylinder rod. The plug pad is fixedly connected with the surface of the bent pipe through an arc-shaped elastic sheet. The surface of the bent pipe is communicated with an arc-shaped pipe.

[0010] Further, three air cylinder rods are communicated with the surface of the positioning frame. The push rod penetrates through the air cylinder rod and extends into the positioning frame. One end of the arc-shaped pipe away from the bent pipe extends into the water tank.

[0011] Further, a stop rod is fixedly connected to the inner wall of the arc-shaped pipe. A rubber plug plate is arranged inside the arc-shaped pipe. The rubber plug plate is fixedly connected with the inner wall of the arc-shaped pipe through an elastic sheet; The bottom of the rubber plug plate contacts the top surface of the stop rod. One end of the rubber plug plate away from the stop rod is movably connected with the inner wall of the arc-shaped pipe through a rotating shaft.

[0012] The beneficial effects of the present invention are as follows: After placing the fan blade to be polished into the operation frame of the present invention, the motor is powered on, so that the motor drives the polishing disc to polish the fan blade. The hydraulic rod is started to push the motor to move downwards, which is convenient for adjusting the polishing thickness. A sliding rod is arranged on the top of the motor. The motor is adjusted by the hydraulic rod. The sliding rod will slide inside the sliding hole block, increasing the stability of the polishing disc during polishing and avoiding severe shaking of the polishing disc during work, resulting in a reduction in polishing efficiency.

[0013] When the present invention needs to fix the fan blade, the distance between the clamping frame and the sealing door is pulled through the adjusting rod, which is convenient for placing the fan blade into the clamping frame. After the fan blade is placed into the clamping frame, the adjusting block is used to twist the adjusting rod. The adjusting gear drives the meshing gear to rotate through the rotation of the adjusting rod. The threaded rod pushes the threaded hole frame to slide on the surface of the positioning plate through the rotation of the meshing gear, so that the two threaded hole frames can move closer to each other through the threaded connection with the threaded rod to clamp the fan blade. A rubber block is arranged inside the clamping frame to protect the fan blade through the rubber block and avoid curling of the fan blade when the clamping frame clamps the fan blade.

[0014] When the fan blade is pushed into the interior of the clamping frame of the present invention, the fan blade will expand by extruding the cylindrical block through the inclined groove on the surface of the cylindrical block. When the cylindrical block expands, it clamps and fixes the fan blade through the elasticity of the elastic rod. A protective pad is arranged inside the inclined groove to increase the friction between the fan blade and the cylindrical block, so that the fan blade can be fixed inside the clamping frame through the extrusion of the cylindrical block, increasing the stability when fixing the fan blade.

[0015] When the motor of the present invention drives the rotating rod to rotate, the rotation will push the inclined plane block to move through the extrusion rod. The connecting rod pushes the cylindrical rod to rotate on the surface of the round rod through the extrusion of the inclined plane block. When the cylindrical rod rotates, it pulls the telescopic rod to move. The push rod pushes the sealing pad to move inside the air cylinder rod through the movement of the telescopic rod. After the extrusion rod separates from the surface of the inclined plane block, the movable plate pushes the inclined plane block to reset through the elasticity of the elastic rod, so that the push rod can push the sealing pad to reciprocate inside the air cylinder rod. The gas inside the air cylinder rod is discharged into the inside of the elbow pipe through the extrusion of the sealing pad, and the air cylinder discharges through the elbow pipe to clean the waste on the surface of the fan blade, increasing the polishing efficiency.

[0016] When the sealing pad contracts inside the air cylinder rod through the push rod of the present invention, the blocking pad will block the bottom of the elbow pipe, so that the suction force generated by the sealing pad can suck the clear water inside the water tank into the air cylinder rod through the arc pipe. When the sealing pad discharges the gas through the push rod, the rubber blocking plate contacts the surface of the blocking rod to seal the arc pipe, so that the clear water can be discharged through the elbow pipe to clean the surface of the fan blade, avoiding the waste adhering to the surface of the fan blade and reducing the polishing efficiency. The water is used to cool the polishing disc by flushing, increasing the service life. Description of the Drawings

When the cylindrical rod 54 rotates, it pulls the telescopic rod 59 to move. The push rod 64 drives the sealing pad 63 to move inside the air cylinder rod 62 through the movement of the telescopic rod 59. After the pressing rod 57 separates from the surface of the inclined block 56, the movable plate 60 pushes the inclined block 56 to reset through the elasticity of the elastic rod 61, so that the push rod 64 can drive the sealing pad 63 to move reciprocally inside the air cylinder rod 62. The gas inside the air cylinder rod 62 is discharged into the inside of the elbow pipe 65 through the extrusion of the sealing pad 63. When the sealing pad 63 contracts inside the air cylinder rod 62 through the push rod 64, the blocking pad 66 will block the bottom of the elbow pipe 65, so that the suction force generated by the sealing pad 63 can suck the clear water inside the water tank into the inside of the air cylinder rod 62 through the arc pipe 68. When the sealing pad 63 discharges the gas through the push rod 64, the rubber blocking plate 71 contacts the surface of the blocking rod 72 to seal the arc pipe 68, so that the clear water can be discharged through the elbow pipe 65 to clean the surface of the fan blade.
