the revolution of the planet gears 102 drives the planet carrier 105 to rotate, and the planet carrier 105 is fixedly connected with the mounting frame 4, so that the mounting frame 4 also rotates.
When the planetary gear 102 rotates, the planetary gear 102 drives the face gear 106 to rotate, when the face gear 106 rotates, the gear 402 drives the first spline shaft 401 to rotate, the first spline shaft 401 rotates to drive the first internal spline tube 403 to rotate, the first internal spline tube 403 drives the first bevel gear 404 to rotate, the first bevel gear 404 rotates to drive the second bevel gear 406 to rotate, and the second bevel gear 406 rotates to drive the second spline shaft 408 to rotate.
(3) The mounting bracket 4 and the second spline shaft 408 rotate simultaneously, wherein:
the spring force of the first spring 413 drives the mounting plate 405 radially so that the polishing belt 505 abuts against the inner wall of the plastic tube.
The rotation of the mounting frame 4 drives the plurality of shells 5 to revolve, so that the shells 5 move on the same circumference.
When the second spline shaft 408 rotates, it drives the second internal spline tube 504 to rotate, and the second internal spline tube 504 rotates to drive the second sleeve 504 and the plate 502 to rotate;
the plate 502 rotates to drive the shell 5 to rotate through the cylinder 501, the shell 5 rotates to drive the polishing belt 505 on the outer edge of the shell 5 to rotate, and the polishing belt 505 rotates to polish the plastic part of the rotating body.
The second sleeve 504 rotates relative to the first sleeve 412, the special-shaped structures of the two end surfaces force the second sleeve 504 to move axially, in addition, due to the elastic force of the second spring 411, during the rotation of the second spline shaft 408, the second sleeve 504 can reciprocate linearly in the axial direction, the second sleeve 504 moves to drive the cylinder 501 to reciprocate linearly in the axial direction through the plate 502, the cylinder 501 is fixedly connected with the shell 5, the shell 5 also reciprocates linearly in the axial direction by a small amplitude, the polishing belt 505 is driven to reciprocate linearly in the axial direction, so that the polishing belt 505 moves axially during the rotation and polishing of the polishing belt 505, the polishing belt 505 can polish plastic parts of the rotating body from more directions, and the polishing quality is improved.
The cylinder 501 reciprocates linearly in the axial direction, the cylinder 501 is displaced relative to the plunger 410, the first check valve on the plunger 410 only allows the outside air to flow into the cylinder 501, so that the air pressure in the cylinder 501 is increased during the axial reciprocation of the cylinder 501, the air pressure in the housing 5 is synchronously increased due to the communication between the housing 5 and the cylinder 501, and the second check valve 507 only allows the air in the housing 5 to flow into the outside, so that the second check valve 507 blows the air to the outside during the reciprocation of the cylinder 501, and the air is discharged and then enters the gap between the cover plate 506 and the deflector 508.
The high-pressure gas blown out of the gap forms an air knife which is diffused to the periphery in a round shape, and the air knife is contacted with the plastic part of the rotating body to perform air cooling and heat dissipation on the polished part, so that the plastic part is prevented from being deformed locally due to overhigh temperature during polishing.
Moreover, since the air knife is positioned in the advancing direction of the polishing belt 505, the air knife can clean the part of the plastic part which is not polished yet.
The foregoing is only a preferred embodiment of the invention, but the scope of the invention is not limited thereto, and any person skilled in the art who is in the field of the invention can apply equivalent substitution or modification to the technical solution and the inventive concept according to the invention within the scope of the invention.
