[0019] In the present invention, when the outer wall of the metal workpiece is polished by the plurality of second polishing pieces, the continuous operation of the mechanical arm drives the second spring telescopic rod to contract. At this time, the side end of the trigger plate and the end of the metal workpiece are in conflict with each other, so that the trigger plate is in conflict and drives the trigger ring to slide into the connecting frame under the action of the first spring telescopic rod, thereby driving the connecting shaft to slide in the limiting sleeve under the action of the wedge block, and causing the limiting disk to compress the reset spring, thereby causing the second gear to disengage from the meshing with the first gear and the synchronous gear disk, thereby causing the auxiliary sleeve disk to stop rotating, causing the plurality of second polishing pieces to stop working, and when the mechanical arm continues to work, driving the trigger tooth groove rod to mesh with the third gear, driving the adjusting bevel gear to rotate, thereby driving the switching bevel gear meshed with it to rotate, and then driving the plurality of control gears to rotate synchronously through the control gear disk, so that the plurality of auxiliary tooth groove rods move closer to the direction of the reference fixed disk, thereby driving the plurality of first arc plates away from the metal workpiece, and driving the plurality of The second arc plate is fixed from the outer wall of the polished metal workpiece, and in the switching process, since the several first polishing members continue to work, the metal workpiece will not be displaced, which makes it convenient for the first polishing member to completely polish the inner wall of the metal workpiece, thereby completing the polishing work, and the damping spring rod is set, so that the polishing work can be carried out continuously, and in the process of fixing the second arc plate, the inclined surface and the retractable setting are used to avoid blocking the movement of the second arc plate when the several second polishing members stop working, thereby avoiding the need for staff to fix it by hand, and the fixing method of the metal workpiece can be changed in time, thereby improving the stability during polishing, further improving the practicality of the device, and at the same time, after the inner and outer walls of the metal workpiece are polished, the trigger plate can be reset under the action of the first spring telescopic rod and the damping spring rod, the second gear can be reset synchronously under the action of the reset spring, and the second polishing member can be reset under the action of the second spring telescopic rod, thereby facilitating the next polishing work and improving the convenience of using the device.

At the same time, the synchronous bevel gear (521) is driven to rotate synchronously by the driving gear plate (517), thereby driving the first gear (522) to rotate synchronously under the action of the fixed shaft (520), and driving the second gear (534) meshing with it to rotate, thereby driving the synchronous gear plate (519) meshing with it to rotate, so that the auxiliary sleeve (518) rotates synchronously, and then the mechanical arm (4) works to drive the synchronous polishing device (5) as a whole to move in the direction of the metal workpiece, so that the outer diameter polishing assembly (7) can synchronously polish the outer wall of the metal workpiece; S3: When the outer wall of the metal workpiece is polished by the plurality of second polishing members (76), the second spring telescopic rod (75) is driven to retract by the continuous operation of the mechanical arm (4). At this time, the side end of the trigger plate (541) and the end of the metal workpiece are in contact with each other, so that the trigger plate (541) is in contact with each other and drives the trigger ring (538) to slide into the connecting frame (531) under the action of the first spring telescopic rod (539). Under the action of the wedge block (537), the connecting shaft (533) is driven to slide in the limiting sleeve (532), and the limiting plate (535) compresses the reset spring (536), so that the second gear (534) is disengaged from the first gear (522) and the synchronous gear plate (519), so that the auxiliary sleeve plate (518) stops rotating, and the plurality of second polishing members (76) stop working. 4) When the operation is continued, the trigger toothed rod (103) and the third gear (102) are driven to mesh with each other, driving the adjusting bevel gear (101) to rotate, thereby driving the switching bevel gear (90) meshing therewith to rotate, and then driving the plurality of control gears (86) to rotate synchronously through the control gear plate (83), so that the plurality of auxiliary toothed rods (87) move toward the direction of the reference fixing plate (85), thereby driving the plurality of first arc plates (88) away from the metal workpiece, and driving the plurality of second arc plates (89) to be fixed from the outer wall of the polished metal workpiece. In the switching process, since the plurality of first polishing members (66) continue to work, the metal workpiece will not be displaced, thereby facilitating the first polishing member (66) to completely polish the inner wall of the metal workpiece, thereby completing the polishing work. The damping spring rod (540) is provided, so that the polishing work can be continued.
