The working principle is as follows: when the inner surface polishing machine for stainless steel pipe production is used, the servo motor 16 is started to drive the transmission wheel 73 to rotate, the transmission wheel 73 is meshed with the transmission column 74, so that the mounting column 71 can rotate, the sliding connection relation between the transmission block 75 and the transmission groove 72 is matched, and the characteristic of an inclined notch is added, so that the mounting column 71 can move in a reciprocating mode while rotating, the rotation is positive and negative, the mounting rod 9 and the polishing head 6 on the outer wall of the mounting rod can be driven to rotate, and polishing and burnishing are completed.
Meanwhile, when the reciprocating movement is carried out, the pushing part can push the scraps forward, so that the scraps are prevented from being left on the inner wall.
When the operation mechanism 7 works, the sheave transmission mechanism is driven to work, the motor is started, so that the second rotating shaft 54 drives the limiting ring 53 and the limiting column 56 to rotate, the halving sheave 52 can be stirred to rotate through the groove when the limiting column 56 rotates to a certain degree, the outer wall of the limiting ring 53 can form fixed limit on the halving sheave 52 through arc design when the limiting column 56 leaves the groove, therefore, the first rotating shaft 51 and the gear 57 can be driven to rotate intermittently when the second rotating shaft 54 rotates, the rack 58 can be driven to move due to the meshing connection relationship of the gear 57 and the rack 58, the moving directions of the rack 58 and the mounting platform 2 can be determined by setting the positive and negative rotation of the motor, and therefore, the rack 58 drives the mounting platform 2 and the operation mechanism 7 at the top of the mounting platform 2 to intermittently step towards the stainless steel pipe 10.
The intermittent stepping of the mounting platform 2 and the rack 58 thereof can be matched with the operation mechanism 7 to axially polish and polish the inner wall of the stainless steel pipe 10, so that the inner surface of the stainless steel pipe 10 can be completely polished.
Further, the sheave drive mechanism is matched with the propelling part, and the propelling part can be driven by the drive mechanism to reciprocate, so that the polishing scraps in the stainless steel pipe 10 can be totally pushed out of the stainless steel pipe 10 through the matching of the sheave drive mechanism, the cleaning is completed, and the influence of the scraps on the polishing is prevented.
When the driving mechanism drives the mounting column 71 to rotate forward and backward and move back and forth, the annular groove, the transmission rod 86 and the mounting seat 76 are matched with each other, so that the mounting column 71 can move back and forth to drive the mounting seat 76 to move back and forth, the piston plate 85 can be driven to move back and forth on the inner wall of the mounting cylinder 81, the cleaning liquid and the polishing agent in the two mounting cylinders 81 can be squeezed into the mounting rod 9 through the hose 82 and the infusion pipeline 84, then the cleaning liquid and the polishing agent are sprayed onto the inner surface of the stainless steel pipe 10 through the spraying heads 12, and meanwhile, the automatic feeding of two solutions can be realized.
The standard parts used in the above embodiments may be purchased directly from the market, and the non-standard structural parts described in the specification and drawings may be processed without any doubt according to the common general knowledge in the art, and the connection manner of the respective parts is by the conventional means developed in the art, and the machines, parts and equipment are of the conventional type in the art, so that the detailed description thereof is omitted.
