[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] like Figure 1-3As shown, a polishing machine with a cloth wheel 35 includes a housing 1, a turntable mechanism 2, and three polishing mechanisms 3. The turntable mechanism 2 includes a divider, a turntable 21, and a clamp 22. The divider is mounted on the housing 1 and its power output end is connected to the turntable 21. The clamps 22 are evenly distributed around the turntable 21. The three polishing mechanisms 3 are circumferentially distributed around the turntable mechanism 2 and fixed to the housing 1. The three polishing mechanisms 3 are divided into a first polishing mechanism 301, a second polishing mechanism 32, and a third polishing mechanism 303. Each of the three polishing mechanisms 3 includes a lifting drive device 31, a mounting base 32, a rotary drive device 33, a mounting shaft 34, and a cloth wheel 35. The lifting drive device 31 is mounted on the housing 1 and its power output end is connected to the mounting base 32. The mounting shaft 34 is horizontally arranged and rotatably connected to the mounting base 32. The cloth wheel 35 is mounted on the front end of the mounting shaft 34. The device 33 is mounted on the mounting base 32 and its power output end is connected to the mounting shaft 34; the hardness of the cloth wheel 35 of the first polishing mechanism 301 is greater than that of the cloth wheel 35 of the second polishing mechanism 32; the hardness of the cloth wheel 35 of the third polishing mechanism 303 is less than that of the cloth wheel 35 of the second polishing mechanism 32; the cloth wheel 35 of the third polishing mechanism 303 is coated with wax; the workpiece is placed on the fixture 22, the divider controls the turntable 21 to rotate in increments, and the rotation of the turntable 21 controls the movement of the fixture 22. The workpiece is polished by three sets of polishing mechanisms 3. The polishing mechanism 3 in this design uses cloth wheel 35 for polishing, which can adapt to the arc surface polishing of the product edge. The lifting drive device 31 adjusts the height of the cloth wheel 35. The hardness of the cloth wheel 35 of the three sets of polishing mechanisms 3 gradually decreases, and coarse grinding, fine grinding and precision grinding are performed in sequence. The cloth wheel 35 of the third polishing mechanism 303 is coated with wax to achieve mirror polishing of the workpiece with high polishing precision.

[0021] In this design, the cloth wheel 35 of the first polishing mechanism 301 is made of denim, the cloth wheel 35 of the second polishing mechanism 32 is made of rainproof cloth, and the cloth wheel 35 of the third polishing mechanism 303 is made of velvet.

[0022] The rotary drive device 33 includes a polishing dust explosion-proof motor 331 and a double-pulley transmission assembly 332. The polishing dust explosion-proof motor 331 is mounted on the mounting base 32 and its power output end is connected to the mounting shaft 34 through the double-pulley transmission assembly 332. The polishing dust explosion-proof motor 331 is used to prevent dust explosion caused by electric sparks generated by the motor, and the double-pulley transmission assembly 332 is used to improve stability.

[0023] The lifting drive device 31 includes a servo motor and a lead screw; the servo motor is installed inside the housing 1 and its power output end is connected to the lead screw; the lead screw is rotatably connected to the housing 1 and connected to the mounting base 32 through a lead screw nut; the mounting base 32 is connected to the housing 1 through a guide rod 321, and the servo motor controls the lead screw to rotate, thereby driving the mounting base 32 to lift and adjust the height position of the cloth wheel 35.

[0024] The clamp 22 includes an elastic inner support clamp 221, a pull rod 222, and a cylinder. The elastic inner support clamp 221 is fixed above the turntable 21. The top of the elastic inner support clamp 221 is provided with an annular support groove 2211. The pull rod 222 is slidably connected to the elastic inner support clamp 221. The cylinder is installed at the bottom of the turntable 21 and its power output end is connected to the pull rod 222. When the workpiece is placed on the annular support groove 2211, the cylinder controls the pull rod 222 to move downward. The upper end of the pull rod 222 has a conical structure, which expands the elastic inner support clamp 221 outward, thereby clamping the workpiece.

[0025] The chassis 1 is equipped with a dust cover 4; the front of the dust cover 4 is provided with an operation port 41; the upper end of the dust cover 4 is provided with an exhaust port 42 to prevent dust from being blown out.

[0026] The fixture 22 described in this design is set up in fifteen sets. The two sets of fixtures 22 on the side near the operation port 41 are respectively the loading station and the unloading station. The workpiece is manually loaded from the loading station and transported to the next station. The fixture 22 clamps the workpiece. After being polished by three sets of polishing mechanisms 3, it is transported to the unloading station. The fixture 22 releases the workpiece and waits for manual unloading.
