[0026] Reference Figure 1 , Figure 2 A pot outer flange polishing machine comprises a base 1, on which a rough polishing station and a fine polishing station are symmetrically arranged on the left and right sides, and each station comprises a polishing wheel driving device 2 and a pot driving device 3 corresponding to each other;

[0027] Reference Figure 4 The polishing wheel driving device 2 includes a polishing wheel 22 driven to rotate by a first motor 21. The first motor 21 drives the synchronous wheel and the synchronous belt, thereby driving the polishing wheel 22 mounted on the main shaft to rotate. The second motor 23 drives the polishing wheel 22 to move forward and backward. During the polishing process, the polishing wheel 22 will continue to wear and the diameter will change from large to small. The second motor 23 drives the ball screw to rotate, thereby driving the ball nut to rotate, so that the polishing wheel 22 moves along the direction of the pot, and keeps contact and friction with the pot with a set constant torque, so as to solve the problem that the polishing wheel 22 with a continuously decreasing diameter can always polish the pot. The third motor 24 drives the polishing wheel 22 to move up and down; the third motor 24 can realize the polishing wheel 22 to do fine adjustment in the up and down directions, so as to ensure that the polishing wheel 22 is always aligned with the position of the outer flange of the pot that needs to be polished.

[0028] The specific structure is as follows: a guide column is fixedly installed on the base 1, a slide seat is installed outside the guide column, a third motor 24 is arranged on the guide column to control the slide seat to move up and down along the guide column, the slide seat is slidably installed with the polishing wheel seat through a guide rail, a second motor 23 is arranged on the polishing wheel seat to control the polishing wheel seat to move forward and backward relative to the slide seat, the polishing wheel seat is connected to the polishing wheel 22 through the main shaft, and the polishing wheel 22 is driven by the first motor 21 to rotate through the main shaft.

[0029] In order to ensure that the guide column and the base 1 can be accurately aligned during assembly and disassembly to ensure correct installation, the guide column and the base 1 are connected by a key. During installation, the guide column can be fixed to the base 1 and locked by a flange and a clamping block.

[0030] Reference Figure 3 The pot drive device 3 includes a pot positioning mold 31, which is a vacuum adsorption pot positioning mold. After the pot is mounted on the mold for positioning, a vacuum generator or a vacuum pump generates a vacuum to suck the pot. The first drive device 32 drives the pot positioning mold 31 to rotate. The first drive device 32 can control the rotation speed through a frequency converter, thereby realizing stepless adjustment of the pot rotation speed. The appropriate pot rotation speed can be achieved by selecting a suitable frequency. The rotation direction of the polishing wheel 22 is opposite to that of the pot positioning mold 31, thereby achieving a better polishing effect. The first drive device 32 drives the pot positioning mold 31 to rotate through a telescopic universal coupling 321. The telescopic universal coupling 321 can realize the free rotation of the pot when adjusting different lifting heights and tilt angles of the pot. The second drive device 33 drives the pot positioning mold 31 to move up and down. The second drive device 33 drives the synchronous wheel to drive the synchronous belt to move up and down to realize the lifting action of the top plate, thereby driving the pot positioning mold 31 to move up and down. The third driving device 34 drives the pot positioning mold 31 to move forward and backward. The third driving device 34 drives the pot positioning mold 31 to move forward and backward through a synchronous belt. The base 1 is provided with a guide rail 11, and the pot driving device 3 is arranged on the guide rail 11, so as to facilitate movement.

[0031] The product is also designed with a pot tilt angle adjustment mechanism 35, which controls the pot positioning mold 31 to polish or grind the pot outer flange bevel, arc surface, straight surface and other parts at any angle. The pot tilt angle adjustment mechanism 35 is a worm gear structure, which is connected to the control hand wheel 351. When the hand wheel rotates, the worm gear structure drives the pot positioning mold 31 to rotate to a certain angle, and then tightening the handle on the locking sleeve can realize the locking of the worm, thereby achieving the purpose of adjusting and locking the pot tilt angle.

[0032] The specific structure is as follows: the base 1 is slidably mounted with a sliding seat through the guide rail 11, the sliding seat is driven by the third driving device 34 to move forward and backward along the guide rail 11, a lifting frame is connected to the sliding seat, the lifting frame is driven by the second driving device 33 to move up and down relative to the sliding seat, a panel of the lifting frame is hinged with a pot positioning mold 31, the pot positioning mold 31 is controlled by the pot tilt angle adjustment mechanism 35 to adjust its angle around the hinge, and a first driving device 32 is arranged on the sliding seat to drive the pot positioning mold 31 to rotate.

[0033] The polishing wheel driving device 2 is provided with a dust collecting and anti-dust cover 25 to reduce the harm of metal dust generated by polishing to operators.

[0034] The device can also be provided with a fixed wax automatic waxing mechanism or a liquid wax automatic waxing device, which is convenient for waxing the polishing wheel at regular intervals during the polishing process. After a certain number of pot polishing jobs have been completed, the first motor 21 can be used to control the polishing wheel 22 to rotate from a high speed state to a low speed state, and enter a waxing state. After the waxing is completed, the first motor 21 will speed up the polishing wheel 22 to a high speed state for polishing.

[0035] In addition, a manipulator is provided on the base 1 to realize the loading, moving and unloading operations of the pot at the rough polishing station and the fine polishing station, effectively improving the automation of polishing. Moreover, an electrical control system is provided on the base 1, and the electrical control system controls the automatic operation of the polishing wheel drive device 2 and the pot drive device 3. The polishing wheel drive device 2 and the pot drive device 3 can be conveniently adjusted and controlled through PLC, touch screen and buttons.
