[0005] The utility model discloses a polishing tool with a replaceable curvature radius, aiming to solve the technical problem that the polishing tool cannot change the curvature radius.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A polishing tool with replaceable curvature radius comprises a frame, the outer surface of the frame is fixedly connected to an external threaded tube, the outer surface of the external threaded tube is threadedly connected to an internal threaded tube, the outer surface of the internal threaded tube is fixedly connected to a first fixed block, the first fixed block is fixedly connected to a side away from the internal threaded tube, the outer surface of the ring is slidably connected to a polishing mechanism, the polishing mechanism comprises a sliding sleeve, the sliding sleeve is slidably connected to the outer surface of the ring, the upper surface of the sliding sleeve is fixedly connected to a support rod, the outer side surface of the end of the support rod is fixedly connected to a first limit block, the outer surface of the first limit block is rotatably connected to the limit tube, the upper surface of the limit tube is fixedly connected to a second fixed block, and the upper surface of the second fixed block is fixedly connected to a polishing plate.

[0008] By setting an external threaded tube, the internal threaded tube can be limited, so that when the internal threaded tube is rotated, the outer surface of the external threaded tube can rotate and move up and down. By setting a circular ring, the polishing mechanism will not rotate when the internal threaded tube rotates. By setting a polishing mechanism, the curvature radius of the polishing can be adjusted, so that when polishing parts with special-shaped outer surfaces, the parts can be fully in contact with the outer surface of the special-shaped parts to achieve the polishing effect of the special-shaped parts.

[0009] In a preferred embodiment, the number of the polishing mechanisms is six, and the six polishing mechanisms are all slidably connected to the outer surface of the ring, the bottom end of the polishing plate is fixedly connected to a third fixed block, the outer side of the third fixed block is fixedly connected to a track tube, and the inner cavity of the track tube is slidably connected to a second limit block.

[0010] By setting up six polishing mechanisms, they can be arranged in a surrounding manner to fully contact the outer surface of the special-shaped part. By setting up a track tube, the second limit block can be limited, so that the second limit block can produce a lateral movement effect.

[0011] In a preferred solution, a servo motor is fixedly connected to the inner wall of the frame, a rotating rod is installed at the output end of the servo motor through a coupling, a placement mechanism is fixedly connected to the top end of the rotating rod, the placement mechanism includes a rotating tube, the rotating tube is fixedly connected to the top end of the rotating rod, a rotating frame is fixedly connected to the top end of the rotating tube, a limit frame is fixedly connected to the outer side surface of the rotating frame, the second limit block is frictionally matched with the inner wall of the limit frame, a spring is fixedly connected to the bottom surface of the inner wall of the rotating tube, a blocking block is fixedly connected to the top end of the spring, a sealing ring is fixedly connected to the outer surface of the blocking block, the sealing ring is frictionally matched with the inner wall of the rotating tube, a soft pad is fixedly connected to the upper surface of the blocking block, and the number of the soft pads is several, and the several soft pads are evenly distributed.

[0012] By setting up a servo motor, the rotating rod can be rotated after the power is connected and the switch is turned on. By setting up a rotating tube, the rotating frame can be rotated together with the rotating rod. The setting of the limit frame can limit the second limit block, so that the polishing plate can become stable when the angle changes. By setting up a blocking block and a sealing ring, the effect of vertical up and down movement can be produced in the inner cavity of the rotating tube. By setting up a soft pad, the outer surface of the part can be protected.

[0013] As can be seen from the above, a polishing tool with a replaceable curvature radius has the following improvements and advantages compared with the prior art:

[0014] First, by setting up a polishing mechanism, the curvature radius of the polishing can be adjusted, so that when polishing parts with special-shaped outer surfaces, the outer surface of the special-shaped parts can be fully contacted to achieve the polishing effect of the special-shaped parts.

[0015] Secondly, by setting the rotating tube, the rotating frame can rotate together when the rotating rod rotates. The setting of the limit frame can limit the second limit block, so that the polishing plate can become stable when the angle changes. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The utility model discloses a polishing tool with a replaceable curvature radius, which is mainly used in scenarios where the polishing tool cannot change its curvature radius.

By setting the polishing mechanism 8, the curvature radius of polishing can be adjusted, so that when polishing parts with special-shaped outer surfaces, they can fully contact with the outer surface of the special-shaped parts to achieve the polishing effect of the special-shaped parts.

[0025] Reference Figure 2 and Figure 3In a preferred embodiment, the number of the polishing mechanisms 8 is six, and the six polishing mechanisms 8 are all slidably connected to the outer surface of the ring 7. By setting up six polishing mechanisms 8, they can be arranged in a circle, so as to fully contact the outer surface of the special-shaped parts. The bottom end of the polishing plate 86 is fixedly connected with a third fixed block 87, and the outer side of the third fixed block 87 is fixedly connected with a track tube 88. The inner cavity of the track tube 88 is slidably connected with a second limit block 89. By setting the track tube 88, the second limit block 89 can be limited, so that the second limit block 89 can produce a lateral movement effect. When in use, when it is necessary to adjust the polishing curvature radius, the operator rotates the internal threaded tube 5, so that the internal threaded tube 5 rotates and moves upward on the outer surface of the external threaded tube 4, so that the ring 7 moves upward. During the movement, the ring 7 squeezes the support rod 82, so that the limit tube 84 rotates on the outer surface of the first limit block 83, thereby causing the polishing plate 86 to produce a stirring change.

[0026] Reference Figure 2 In a preferred embodiment, a servo motor 2 is fixedly connected to the inner wall of the frame 1, a rotating rod 3 is installed at the output end of the servo motor 2 through a coupling, and a placement mechanism 9 is fixedly connected to the top of the rotating rod 3.

By setting the soft pads 95, the outer surface of the part can be protected. During use, when polishing is required, the operator brings the soft pad 95 into contact with the outer surface of the part, and then connects the servo motor 2 to the power supply and turns on the switch of the servo motor 2, so that the rotating rod 3 drives the rotating tube 91 and the rotating frame 92 to rotate, so that the polishing mechanism 8 polishes the outer surface of the part.

[0028] Working principle: During use, when the polishing curvature radius needs to be adjusted, the operator rotates the internal threaded tube 5, so that the internal threaded tube 5 rotates on the outer surface of the external threaded tube 4 and moves upward, thereby causing the ring 7 to move upward. During the movement, the ring 7 squeezes the support rod 82, so that the limiting tube 84 rotates on the outer surface of the first limiting block 83, thereby causing the polishing plate 86 to produce a stirring change.

[0029] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution.
