The working principle of the invention is as follows: firstly, placing a computer shell on a first sanding belt 3, starting a double-shaft motor 7, driving the first sanding belt 3 to rotate by the output end of the double-shaft motor 7 through a second output tooth 703 and a belt driving tooth 704, so that the computer shell is conveyed between an upper pressure plate 1 and a lower pressure plate 2, then stopping the double-shaft motor 7, connecting a pull rod 104 with external hydraulic equipment, enabling the pull rod 104 to push the upper pressure plate 1 to move downwards, enabling the upper pressure plate 1 to extrude the computer shell, firstly, attaching a fixed pressure plate 105 to the outer side of the computer shell, aligning the fixed pressure plate 105 with a support strip 204, fixing the computer shell through the extrusion of the fixed pressure plate 105 and the support strip 204, and at the moment, downwards extruding the first sanding belt 3 by the computer shell, enabling the first sanding belt 3 to pull a deflection shaft 5 to rotate upwards, enabling the first sanding belt 3 to be inserted between the two sets of support strips 204, and enabling the first sanding belt 3 to extrude a thimble 601, the thimble 601 pushes the transmission mechanism 6 to move downwards integrally, so that the sleeve ring extrudes the return spring 605 through the lower pressing rod 604, the transmission teeth 602 are attached to the outer wall of the output belt 702, then the upper pressing plate 1 continues to move downwards, so that the fixed pressing plate 105 is inserted into the sliding chute plate 102 and extrudes the spring in the sliding chute plate 102, and the bending plate 101 extrudes and bends the edge part of the computer case, so that the edge of the computer case is aligned with the drill hole 201 on the outer side of the lower pressing plate 2 until the second grinding belt 4 is attached to the top end of the computer case;

after bending is finished, the double-shaft motor 7 is started again, firstly, the double-shaft motor 7 continuously drives the second output teeth 703 and the belt driving teeth 704 to rotate, so as to drive the first polishing belt 3 to rotate again, but at the moment, the computer shell is clamped by the fixed pressing plate 105 and the supporting bars 204, the first polishing belt 3 and the computer shell generate relative displacement therewith, so that the first polishing belt 3 polishes the bottom end of the computer shell, and when the upper pressing plate 1 moves downwards, the transmission roller 9 is driven to synchronously move downwards, so that the rubber driven wheels 901 arranged at two sides of the transmission roller 9 are attached to the outer wall of the rubber transmission wheel 502, when the first polishing belt 3 polishes the bottom end of the computer shell, the transmission roller 9 is driven to rotate by the rubber transmission wheel 502 and the rubber driven wheels 901, so as to drive the second polishing belt 4 to rotate, so that the second polishing belt 4 polishes the top end of the computer shell, the top end and the bottom end of the computer shell can be synchronously polished, so that the use efficiency is improved;

meanwhile, the output end of the double-shaft motor 7 drives the first output tooth 701 and the output belt 702 to rotate, so that the output belt 702 drives the transmission teeth 602 in transmission connection therewith to rotate, the transmission teeth 602 drive a plurality of groups of transmission mechanisms 6 to rotate, the transmission mechanisms 6 push the drilling mechanisms 8 to move outwards through screws at the end parts, the threaded friction ring 801 drives the pushing ring 802 to rotate and advance through a protruding circular ring at the outer side and a plurality of groups of friction blocks 803, so that the pushing ring 802 pushes the drill bit 806 to move forwards through the limiting ring 808, the drill bit 806 passes through the drill hole 201 to extend to the outer side of the lower pressing plate 2, the end part of the drill bit 806 is inserted into the screw through the inserted rod 807, the outer wall of the inserted rod 807 is provided with a plurality of groups of grooves, the screw rod can drive the inserted rod 807 to rotate through the grooves, so as to drive the drill bit 806 to rotate, and the drill bit 806 to the bent edge of the computer case, the drill 806 is hard with the computer case, so that the drill 806 cannot drill the computer case quickly, the push ring 802 cannot move forward at a speed matched with the screw, at the moment, the torque between the protrusion of the circular ring outside the threaded friction ring 801 and the push ring 802 is greater than the maximum static friction force between the threaded friction ring 801 and the push ring 802, and the friction block 803 is extruded into the threaded friction ring 801 through the inclined surface outside, so that the threaded friction ring 801 is not limited by the push ring 802 and rotates synchronously with the screw, the threaded friction ring 801 rotates under the driving of the screw, so that the threaded friction ring 801 does not drive the push ring 802 to move forward, and the overload of the drilling mechanism 8 during drilling is avoided, so that the drill 806 can adapt to computer cases with different hardness, and the use range is improved;

after drilling is finished, the drill bit 806 needs to be reset, at the moment, the double-shaft motor 7 needs to be started reversely, the double-shaft motor 7 drives the transmission mechanism 6 to rotate reversely, the screw rod drives the threaded friction ring 801 reversely, so that the drill bit 806 is pulled to be retracted into the drill hole 201 from the outer side of the lower press plate 2 through the pushing ring 802, at the moment, the second output teeth 703 trained at the output end of the double-shaft motor 7 also drive the belt driving teeth 704 and the first polishing belt 3 to rotate reversely, the first polishing belt 3 drives the second polishing belt 4 to rotate reversely through the deflection shaft 5, so that secondary reverse polishing can be performed on the computer shell, the computer shell can be polished bidirectionally, the polishing effect is improved, after the drill bit 806 is reset, external hydraulic equipment is started, the upper press plate 1 is not pressing the computer shell, the computer shell is not pressing the first polishing belt 3, the torsion spring sleeved outside the deflection shaft 5 through the deflection rod 504 returns, the first sanding belt 3 is straightened again, so that the first sanding belt 3 does not extrude the thimble 601, the return spring 605 pushes the transmission mechanism 6 to return, the first sanding belt 3 pulls the bent computer shell from the lower pressing plate 2, so that the computer shell is separated from the lower pressing plate 2, then the double-shaft motor 7 is started again, the first sanding belt 3 is driven to rotate through the second output teeth 703, so that the first sanding belt 3 drives the computer shell to move, and therefore blanking is performed on the computer shell.
