When the sliding sleeve gear 303 meshes with the expansion gear 206, the expansion gear 206 drives the sliding sleeve gear 303 and the outer sliding sleeve 302 to rotate, so that the convex ball 309 slides in the bidirectional screw 308 by a distance, so that the outer sliding sleeve 302 and the expansion barrel 304 slide along the sliding groove 313, thereby driving the expansion rod 305 to rotate, thereby driving the inner polishing head 307 to slide outward relative to the end block 306 by a distance, so that the inner polishing head 307 contacts and polishes the inner wall of the cathode roller 4. Subsequently, the sliding frame 201 moves the inner rotating column 301 and the inner polishing head 307 away from the cathode roller 4. At this time, the inner wall of the cathode roller 4 is polished by the inner polishing head 307. Subsequently, the inner polishing head 307 moves to the outermost side. Then, the sliding frame 201 starts to move towards the cathode roller 4 again. When the sliding sleeve gear 303 meshes with the expansion gear 206 again, the inner polishing head 307 slides outward by a distance again, so that the inner polishing head 307 further polishes the inner wall of the cathode roller 4. In this way, the inner polishing head 307 will move outward several times, and the inner wall of the cathode roller 4 will be polished gradually. When the convex ball 309 moves to the innermost position of the bidirectional screw 308, the expansion gear 206 drives the sliding sleeve gear 303 to rotate again, so that the outer sliding sleeve 302 and the expansion barrel 304 retreat along the sliding groove 313, so that the inner polishing head 307 is retracted, so that the inner polishing head 307 is separated from the inner wall of the cathode roller 4. Subsequently, after several retreats, the inner polishing head 307 returns to the initial state, and the polishing of the inner wall of the cathode roller 4 is completed.

[0050] The working principle of the high-precision grinding machine for the cathode roller is as follows: the cathode roller 4 is placed on the bottom support 111, the cathode roller 4 presses the supporting block 129, the compression spring 132 is compressed, when the supporting block 129 is not pressed, the clamping block 130 is located in the sliding groove in the lower row of the supporting block 129, when the supporting block 129 is pressed, the clamping block 130 is located in the sliding groove in the upper row of the supporting block 129, the position of the supporting block 129 is locked through the clamping spring 131 and the clamping block 130, at this time, the switch 128 is started, the electric cylinder 107 is elongated to push the push column 110 to slide along the bottom support 111, the driving rotary ring 121 and the rotary gear 117 are pushed to slide along the bottom support 111, so that the cathode roller 4 is inserted into the driving rotary ring 121 and the driving spring 127 is compressed, then the driving rotary ring 121 pushes the cathode roller 4 to move together, the cathode roller 4 is inserted into the passive rotary ring 122, the passive spring 124 is compressed, the cathode roller 4 lifts the outer grinding head 211, the outer friction spring 203 is compressed, the passive clamping block 123, the driving clamping block 126 and the inner friction block 125 allow the cathode roller 4 to move axially, and the cathode roller 4 is clamped at both ends through the driving rotary ring 121 and the passive rotary ring 122, so that the cathode roller 4 is clamped and can rotate under the driving of the driving rotary ring 121, at this time, the rotary gear 117 reaches below the butt joint gear 116, and the movement of the push column 110 drives the jacking column 133 to move towards the lifting block 118, the jacking column 133 pushes the lifting block 118, so that the return spring 119 is compressed, the lifting block 118 is away from below the lifting disc 120, the contact short rod 113 rotates around the bottom support 111 under the action of gravity, so that the butt joint gear 116 is engaged with the rotary gear 117, at the same time, the bottom motor 102 rotates to drive the rotating shaft 104, the sliding column 105, the lower gear 106 and the motor wheel 108 to rotate, the transmission wheel 112 is driven to rotate through the lower transmission belt 109, the upper wheel 115 and the butt joint gear 116 are driven to rotate through the upper transmission belt 114, so that the rotary gear 117 and the driving rotary ring 121 are driven to rotate, thereby driving the cathode roller 4 to rotate. The rotation of the lower gear 106 drives the gear ring 204 to rotate, thereby driving the bidirectional screw rod 202 and the sliding frame 201 to slide along the bottom plate 101 through the inner convex ball 205, the gear ring 204 drives the opening gear 206 to rotate, the lower rotating sleeve 207 slides along the sliding column 105, at the same time, the sliding column 105 drives the lower rotating sleeve 207 and the lower transmission wheel 208 to rotate, the inner rotating column 301 is driven to rotate and slide towards the cathode roller 4 through the vertical transmission belt 209, since the surface of the bidirectional screw rod 202 is provided with bidirectional threads, when the sliding frame 201 moves to the limit position, it starts to move reversely, so that the inner rotating column 301 rotates while the sliding frame 201 reciprocally slides along the bottom plate 101, when the sliding frame 201 reciprocally slides along the bottom plate 101, the outer surface of the cathode roller 4 is repeatedly ground through the outer grinding head 211 in cooperation with the rotation of the cathode roller 4.When the inner rotating column 301 starts to rotate, the outer sliding sleeve 302 and the sliding sleeve gear 303 are driven to rotate synchronously by the clamping tooth 310 and the inner tooth 312, so that the outer sliding sleeve 302, the sliding sleeve gear 303, the expansion cylinder 304, the expansion rod 305, the end block 306, the inner polishing head 307 and the inner rotating column 301 rotate synchronously, at this time, the convex ball 309 does not slide relative to the bidirectional screw 308, the expansion cylinder 304 does not slide relative to the inner rotating column 301, at this time, the inner polishing head 307 has not contacted the inner wall of the cathode roller 4, the inner polishing head 307 rotates together with the inner rotating column 301 and moves together with the sliding frame 201 towards the cathode roller 4, when the sliding sleeve gear 303 meshes with the expansion gear 206, the expansion gear 206 drives the sliding sleeve gear 303 and the outer sliding sleeve 302 to rotate, so that the convex ball 309 slides in the bidirectional screw 308 for a distance, so that the outer sliding sleeve 302 and the expansion cylinder 304 slide along the sliding groove 313, thereby driving the expansion rod 305 to rotate, thereby driving the inner polishing head 307 to slide outward relative to the end block 306 for a distance, so that the inner polishing head 307 contacts and polishes the inner wall of the cathode roller 4, then the sliding frame 201 moves the inner rotating column 301 and the inner polishing head 307 away from the cathode roller 4, at this time, the inner wall of the cathode roller 4 is polished by the inner polishing head 307, then the inner polishing head 307 moves to the outermost side, then the sliding frame 201 starts to move towards the cathode roller 4 again, when the sliding sleeve gear 303 meshes with the expansion gear 206 again, the inner polishing head 307 slides outward for a distance again, so that the inner polishing head 307 further polishes the inner wall of the cathode roller 4, and so on, the inner polishing head 307 will move outward several times, and the inner wall of the cathode roller 4 is polished gradually, when the convex ball 309 moves to the innermost position of the bidirectional screw 308, the expansion gear 206 drives the sliding sleeve gear 303 to rotate again, so that the outer sliding sleeve 302 and the expansion cylinder 304 retreat along the sliding groove 313, so that the inner polishing head 307 is retracted, so that the inner polishing head 307 is separated from the inner wall of the cathode roller 4, then after several times of retreat, it returns to the initial state, and the polishing of the inner wall of the cathode roller 4 is completed.
