Working principle: the valve body is sleeved on the centering table 13211, the valve body seat extrudes the locking mechanism, the locking spring 83 compresses, the feeding motor 14 and the polishing motor 31 are started, the feeding motor 14 drives the driving column 133 to rotate, the feeding column 132 is driven to rotate when the driving column 133 rotates, the sliding column 1322 is driven to slide on the arc rail 1311 of the driven column 131 when the feeding column 132 rotates, the feeding column 132 is driven to slide on the driving column 133 under the action of the inclined plane of the arc rail 1311, the object placing table 1321 above the feeding column 132 is driven to move upwards, meanwhile the feeding column 132 rotates, the valve body is not subjected to external force, and the valve body and the feeding column 132 synchronously rotate.
In the process, the rotation friction force received by the driven column 131 is smaller than the elastic force of the limit spring 23, the limit spring 23 is in a static state, the limit ball 21 is in contact with the limit hole, and the driven column 131 is in a static state; the polishing motor 31 drives the clutch shaft 34 to rotate, the clutch shaft 34 drives the driving gear post 32 to rotate, the reset spring 35 is in an extension state, the driven gear post 33 and the driving gear post 32 are in a non-contact state, and the driven gear post 33 does not rotate.
The feeding column 132 drives the valve body to move upwards, the polishing column 43 enters the valve body, when the polishing column 43 contacts with the bottom of the valve body, the object placing table 1321 on the feeding column 132 drives the valve body to move upwards, the valve body pushes the polishing column 43 to drive the adjusting shaft 42 to move upwards, the adjusting shaft 42 slides in the expanding shaft 41, the swinging rods 71 and the transmission rods 72 of the multiple groups of connecting rod mechanisms swing, the connecting rod mechanisms push the expanding wings 5 to expand outwards, when the expanding wings 5 expand outwards, the polishing mechanism is driven to move towards the inner wall close to the valve body, and the valve body pushes the polishing column 43 to move upwards until the polishing blocks 61 on each group of the expanding wings 5 completely fit the inner wall of the valve body.
In this process, the friction between the polishing column 43 and the valve body increases, the polishing column 43 does not rotate, the feeding column 132 drives the valve body to rotate, so that the valve body and the object placing table 1321 rotate relatively, a part of the locking blocks 81 slide into the bolt holes of the valve body seat, the locking springs 83 restore to the initial positions, the valve body is fixed, and thereafter, the feeding column 132 drives the valve body to rotate synchronously when rotating.
After the polishing blocks 61 on each group of expansion wings 5 are completely attached to the inner wall of the valve body, the valve body is driven by the feeding column 132 to move upwards, the expansion shaft 41 is driven by the expansion shaft 41 to move upwards, the driven tooth column 33 is driven by the expansion shaft 41 to move towards the driving tooth column 32, the reset spring 35 is compressed until the driven tooth column 33 is in contact fit with the driving tooth column 32, the driving tooth column 32 drives the expansion shaft 41 to rotate through the driven tooth column 33, the expansion shaft 41 drives the polishing mechanism on the expansion wings 5 to rotate through the connecting rod mechanism, and the polishing column 43 is driven by the expansion shaft 41 to rotate through the adjusting shaft 42.
After the driven tooth post 33 contacts with the driving tooth post 32, the expansion shaft 41 stops moving upwards, the driven tooth post 33 stops moving upwards, the valve body on the feeding post 132 stops moving upwards, at this time, the driving post 133 drives the feeding post 132 to rotate continuously, the rotating friction force born by the driven post 131 increases, the limiting spring 23 compresses until the rotating friction force born by the driven post 131 is larger than the elastic force of the limiting spring 23, the limiting ball 21 is disconnected from the limiting hole, and the driven post 131 starts rotating.
Because the rotation direction of the driven post 131 is opposite to the rotation direction of the extension shaft 41, the rotation direction of the valve body is opposite to the rotation direction of the polishing mechanism, the polishing post 43 polishes the bottom of the inner wall of the valve body, and the polishing mechanism polishes the inner wall of the valve body, thereby completely and rapidly polishing the inner wall of the valve body.
After polishing is completed, the feeding motor 14 reversely rotates to drive the driving post 133 to reversely rotate, the feeding post 132 drives the valve body to reversely rotate, meanwhile, under the action of the arc rail 1311 on the driven post 131, the feeding post 132 drives the valve body to downwards move, the return spring 35 stretches, the driven tooth post 33 and the expansion shaft 41 downwards move, the contact between the driven tooth post 33 and the driving tooth post 32 is disconnected, the driven tooth post 33 stops rotating, the expansion shaft 41 and the adjusting shaft 42 stop rotating, and the polishing post 43 stops rotating.
Meanwhile, the rotation friction force received by the driven column 131 is smaller than the elastic force of the limiting spring 23, the limiting spring 23 stretches, the limiting ball 21 is in contact with the limiting hole, and the driven column 131 does not rotate any more.
