Working principle:
the magnetic base 2 is magnetically adsorbed on the workbench 102 of the surface grinder 1, the output end of the vacuum pump is connected with the interface 4 through a pipeline, the copper sheet is placed on the surface of the sucker 26, the shape of the root-average copper sheet is communicated with the first through hole 35 and the second through hole 36, then the vacuum pump is started to vacuumize the inside of the sucker 26, and the copper sheet is adsorbed and fixed on the surface of the sucker 26 under the action of pressure.
Then, the grinding wheel 101 is started to rotate, grinding processing is carried out on the copper sheet in the process of rotating the grinding wheel 101, grinding heat is inevitably generated on the copper sheet in the process of grinding the copper sheet by the grinding wheel 101, the grinding heat is transmitted to the memory metal wire 32 through the cylinder 31, the memory metal wire 32 is heated, the heated memory metal wire 32 is contracted in the axial direction of the cylinder 31, the piston 33 is driven to move in the cylinder 31 in the contraction process of the memory metal wire 32, negative pressure is generated in the cylinder 31, the copper sheet is secondarily adsorbed, and air expansion caused by the grinding heat inside the sucker 26 is prevented, so that the stability of the copper sheet is reduced.
Starting the motor 22, the motor 22 rotates to drive the connecting shaft 20 to rotate, the connecting shaft 20 rotates to drive the first bevel gear 21 to rotate, and because the second bevel gear 18 is meshed with the first bevel gear 21, the second bevel gear 18 is driven to rotate when the first bevel gear 21 rotates, the second bevel gear 18 rotates to drive the long shaft 17 to rotate, the long shaft 17 rotates to drive the first incomplete gear 7 and the second incomplete gear 8 to rotate, and the first incomplete gear 7 and the second incomplete gear 8 are driven to rotate, wherein:
when the first incomplete gear 7 is meshed with the second driven gear 12, the second incomplete gear 8 is separated from the reversing gear 9, at the moment, the first incomplete gear 7 drives the second driven gear 12 to rotate, and the second driven gear 12 drives the short shaft 10 to rotate;
when the first incomplete gear 7 is separated from the second driven gear 12, the second incomplete gear 8 is meshed with the reversing gear 9, and the reversing gear 9 is meshed with the first driven gear 11, at this time, the second incomplete gear 8 drives the reversing gear 9 to rotate, the reversing gear 9 drives the first driven gear 11 to rotate, and the first driven gear 11 drives the short shaft 10 to reversely rotate.
Therefore, when the long shaft 17 rotates, the first driven gear 11, the second driven gear 12, the reversing gear 9, the first driven gear 11, and the second driven gear 12 are engaged, and the short shaft 10 is intermittently driven to rotate in the forward and reverse directions.
When the short shaft 10 rotates, the worm 13 is driven to rotate, and as the worm 13 is matched with the worm wheel 16 and the worm wheel 16 is in a fixed state, the worm 13 can revolve around the worm wheel 16, so that in the rotation process of the worm 13, the fixed shaft 15 is used as an axis to rotate, the connecting plate 5 is driven to rotate on the fixed shaft 15, and the connecting plate 5 rotates to drive the sucking disc 26 to rotate around the fixed shaft 15, so that the copper sheet moves in a curve mode.
Because the worm 13 and the worm wheel 16 are matched to have a reverse self-locking function, the sucking disc 26 and the copper sheet adsorbed on the surface of the sucking disc cannot rotate under the action of gravity when the motor 22 is stopped.
Since the stub shaft 10 is intermittently rotated in a forward and reverse direction, the worm 13 is also intermittently rotated in a forward and reverse direction, thereby ensuring that the suction cup 26 reciprocates within a certain range.
The motor 22 will drive the connecting shaft 20 to rotate when rotating, the connecting shaft 20 will drive the third incomplete gear 24 to rotate when rotating, because the third incomplete gear 24 is matched with the rack 37, the rack 37 will be driven to slide in the chute 23 when the third incomplete gear 24 rotates, the sliding direction is always kept as the tangential direction of the curve motion track, the rack 37, the baffle 25 and the sucker 26 are fixedly connected, the sucker 26 will keep the state of synchronously moving with the rack 37, therefore, the sucker 26 will also move along the tangential direction, and the copper sheet will be driven to move on the tangent line, so that the grinding wheel 101 will polish the copper sheet.
As shown in fig. 18-20, in the initial state, the contact point between the copper sheet and the grinding wheel 101 is a tangent point a, the copper sheet moves along the arc line at the bottom of the grinding wheel 101 in the process of performing curve motion, the contact point between the copper sheet and the grinding wheel 101 changes from the tangent point a, and the tangent point b and the tangent point c are two extreme ends of the contact point, namely, the contact point between the copper sheet and the grinding wheel 101 always keeps changing at the tangent point b and the tangent point c.
