[0003] Propeller surface is usually polished gradually from one area to another area in the polishing process, the stress position of propeller changes in the process of transferring polishing area, because the underside of propeller is suspended, the propeller needs to be pressed and covered in the process of polishing propeller, so as to improve the polishing effect of propeller, however, when polishing propeller, propeller is prone to shaking due to uneven stress, and the force of polishing propeller by polishing equipment cannot be accurately controlled when propeller shakes, so the position of propeller pressed and covered by polishing equipment is prone to too large or too small force, when the force of polishing propeller by polishing equipment is too small, the propeller can be polished again by polishing equipment, and when the force of polishing propeller by polishing equipment is too large, the amount of propeller polished by polishing equipment is too large, and the position of propeller polished by polishing equipment is prone to concave, so not only the flatness of propeller is affected, but also the service life of propeller is affected.

[0004] In order to improve the stability of propeller surface, the propeller surface is usually supported by supporting device, since the propeller surface is mostly inclined, the rubber pad is in an inclined state when contacting with the propeller surface, the propeller surface is subjected to horizontal or inclined force by polishing mechanism during the movement of polishing mechanism along the propeller surface, the propeller is prone to shaking after being subjected to the force of polishing mechanism, and the shaking amplitude of propeller increases during the continuous shaking of propeller, so that the propeller is separated from the rubber pad, the supporting effect of supporting mechanism on propeller surface is reduced, therefore, we propose a supporting device for propeller polishing.

[0030] A first bevel gear 48 is coaxially fixedly arranged at a position close to the bottom of the outside of the first screw rod 42, the first bevel gear 48 is rotationally arranged in the interior of the second support cylinder 41 at a position close to the bottom, a second bevel gear 49 is meshingly connected to the first bevel gear 48, a transmission rod penetrating through the side wall of the support cylinder 41 is fixed to the second bevel gear 49, the transmission rod is horizontally arranged, the central axes of the first bevel gear 48 and the second bevel gear 49 are vertically arranged, a rotating disc is fixedly arranged at an end of the transmission rod away from the second bevel gear 49, a rocker is arranged at a position close to one side of the surface of the rotating disc away from the transmission rod, an end of the support rod 43 away from the base 1 penetrates through the top of the second support cylinder 41 and extends above the second support cylinder 41, a worker holds and rotates the rocker, so that the rotating disc drives the transmission rod and the second bevel gear 49 to rotate, the rotating second bevel gear 49 drives the first bevel gear 48 to rotate, and the first screw rod 42 drives the support rod 43 to ascend and approach the paddle 21 through the threaded connection between the first screw rod 42 and the support rod 43 during the rotation of the first screw rod 42.

[0033] By setting a plurality of directional supporting mechanisms 3 and rotating supporting mechanisms 4 with different sizes on the lower side of each paddle 21, the lower side of the paddle 21 is stably supported, so as to improve the stability of the paddle 21 when being polished.

[0034] In the process of moving the polishing mechanism along the surface of the paddle 21, the polishing mechanism will exert a horizontal or inclined force on the paddle 21, and the paddle 21 will be easily shaken after being subjected to the force exerted by the polishing mechanism. In the process of continuous shaking of the paddle 21, the shaking amplitude of the paddle 21 is likely to increase, causing the paddle 21 to separate from the rubber pad, resulting in a decrease in the supporting effect of the supporting mechanism on the paddle 21. To prevent the paddle 21 from separating from the rubber pad, a limiting mechanism 5 is arranged on the rotating supporting mechanism 4, which pulls the side edge of the paddle 21 to fix the position of the rotating supporting mechanism 4 and the paddle 21, thereby preventing the paddle 21 from separating from the rotating supporting mechanism 4.

In the process of rotating the rotating rod 46, the mounting shell 51 is driven to rotate and tilt. When the second rubber pad 47 contacts the surface of the paddle 21, an operator holds and rotates the knob to drive the second screw 52 to rotate. The rotating second screw 52 drives the moving rod 53 to move away from the rotating rod 46. Then, the operator holds the moving plate 54 and moves the moving plate 54 along the axis direction of the trapezoidal slide groove 57. In the moving process, the moving plate 54 drives the limiting block 55 to approach the paddle 21 and avoids the top of the limiting block 55 from exceeding the upper surface of the paddle 21. At the same time, the operator holds and rotates the knob to drive the second screw 52 to rotate in the opposite direction. The second screw 52 drives the moving plate 54 and the limiting block 55 to approach the paddle 21 through the moving rod 53, so that the limiting mechanism 5 positions the paddle 21 and the second rubber pad 47, avoids the paddle 21 from separating from the second rubber pad 47, and improves the supporting effect of the rotating supporting mechanism 4 on the paddle 21.
