After the movable ring rotates, it can drive the limit ring to rotate in the limit ring groove. After the movable ring rotates, the contact between the column rod and the movable groove can push the two groups of column rods closer to one side, and then drive the two groups of positioning rods to move, so that the two groups of positioning rods can clamp the workpiece. After that, the rotating motor can be started to drive the rotating plate to rotate, so that the workpiece can be rotated, which is convenient for circumferential grinding of the workpiece and improves practicality.

[0031] Working principle: Before using the expansion section fully automatic integrated grinder, you need to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5 As shown, when the workpiece is being polished, the workpiece is fixed by the fixing assembly 3, and then the movable frame 106 can be driven to move by the electric cylinder 105, so that the movable rod 103 slides on the fixed frame 102, so that the polishing height can be adjusted, and then the electric push rod 201 can be started to move the mounting plate 204, so that the movable plate 202 can be driven to move, and after the movable plate 202 moves, the fixed plate 208 and the grinding wheel 214 move, and after the movable plate 202 moves, the grinding wheel 214 abuts against the workpiece, and then the movable plate 202 continues to move, and the elastic potential energy of the telescopic spring 205 is greater than the elastic potential energy of the return spring 210, so that after the movable plate 202 moves, the mounting frame 212 no longer moves, so that the fixed plate 208 and the grinding wheel 214 can be driven to move.

The displacement of the mounting plate 204 can be controlled according to the demand of the grinding force, and the grinding force can be adjusted. Then, the driving motor 213 can be started to drive the grinding wheel 214 to rotate, and the workpiece can be ground. When grinding the outer side of the expansion cylinder part workpiece, the grinding wheel 214 can be fitted with the workpiece, which is convenient for grinding along the curved surface of the workpiece, thereby improving the grinding efficiency and grinding quality.

[0032] When fixing the workpiece, the workpiece is placed on the top of the rotating plate 302, and then the hydraulic push rod 315 can be started to extend, so that the movable ring 308 can be driven to rotate counterclockwise. After the movable ring 308 rotates, it can drive the limit ring 309 to rotate in the limit ring groove 310. After the movable ring 308 rotates, the contact between the column rod 311 and the movable groove 312 can push the two groups of column rods 311 closer to one side, and then drive the two groups of positioning rods 307 to move, so that the two groups of positioning rods 307 can clamp the workpiece, and then the rotating motor 303 can be started to drive the rotating plate 302 to rotate, so that the workpiece can be rotated, which is convenient for circular grinding of the workpiece and improves practicality.
