[0026] When the bottom opening of the magnetic head shell 6 is inserted into the shell 5 for fixation, the support plate 7 can support the left and right ends of the magnetic head shell 6 to prevent it from being pulled out of the bottom opening of the shell 5, and the two sets of locking blocks 84 are inserted into the bottom opening of the magnetic head shell 6, while the locking motor 83 drives the positive and negative lead screws 82 to rotate and move the locking blocks 84 towards the inner wall of the magnetic head shell 6 to lock and fix the side wall of the magnetic head shell 6 in the shell 5 to prevent it from sliding out during processing, thereby improving the safety of the processing work.

[0027] The bottom of the box body 3 is provided with a cylinder 9 supporting a circular plate 10, the polishing motor 1 is arranged at the bottom of the circular plate 10 in the cylinder 9, a row of notches 11 is arranged on the angular edge of the top of the circular plate 10, a plurality of gear teeth 12 are arranged on the vertical side wall of the notch 11 in a circumferential direction, a plurality of gears 13 meshing with the gear teeth 12 are arranged in the notch 11, the gears 13 are movably fixed on the protrusions 15 on the outer wall of the cylinder 9 through the rotating shaft 14, one set of protrusions 15 at the bottom is provided with a driving motor 16 connected with the rotating shaft 14, the top of the circular plate 10 is further provided with a camera 17 connected with a display screen 18 through a wire, and a dust removal pipe 19 is arranged on one side of the polishing roller 2 in an inclined manner, and a magnetic adsorption layer is arranged on the outer wall of the dust removal pipe 19.

[0028] When the magnetic head shell 6 needs to be put into the shell 5 for processing, the driving motor 16 drives the gear teeth 12 to rotate through the rotating shaft 14 and the gears 13, so that the gear teeth 12 drive the circular plate 10 to rotate above the cylinder 9, the polishing motor 1 and the polishing roller 2 are driven to rotate to the middle between the front and rear ends of the shell 5 by the circular plate 10, so that the polishing roller 2 has a large gap between the front and rear walls of the shell 5 to facilitate the magnetic head shell 6 to be inserted into the shell 5 and buckled on the polishing roller 2, then the driving motor 16 drives the polishing roller 2 to rotate 90 degrees and contact the polishing starting end of the inner wall of the magnetic head shell 6 through the gears 13, the circular plate 10 and other components, then the polishing motor 1 drives the polishing roller 2 to rotate to polish the inner wall of the magnetic head shell 6, and the electric push rod 4 drives the shell 5 to move the magnetic head shell 6 to the left, so that the polishing roller 2 can completely cover the entire polishing surface of the inner wall of the magnetic head shell 6, then the magnetic head shell 6 is driven to move left and right by the electric push rod 4 and the shell 5, so that the polishing roller 2 can fully polish the inner wall of the magnetic head shell 6.

[0029] When the other inner wall of the magnetic head shell 6 needs to be polished, the driving motor 16 drives the polishing roller 2 to rotate 180 degrees and contact the polishing starting end of the other inner wall of the magnetic head shell 6 through the gears 13, the circular plate 10 and other components, and then the above steps are repeated to polish it.

[0030] The convex block 15 is provided with a rolling bearing 20 for fixing the bottom end of the rotating shaft 14, wherein the rotating shaft 14 is arranged outside the circular plate 10, and the rotating shaft 14 is locked and fixed on the top end of the cylinder 9 by the gear 13 abutting against the bottom wall of the notch 11. When the driving motor 16 drives the circular plate 10 to rotate above the cylinder 9 through the rotating shaft 14 and a group of gears 13 and the toothed 12 engaged with the gears 13, the circular plate 10 is driven by the gear 13 to rotate the remaining groups of gears 13 and the rotating shaft 14 in the rolling bearing 20, preventing the rotation of the circular plate 10, and the groups of gears 13 clamping the side wall of the notch 11 to prevent the horizontal displacement of the circular plate 10 above the cylinder 9, and at the same time, the gear 13 is abutted against the bottom wall of the notch 11 to fix the circular plate 10 above the cylinder 9 to prevent separation.

[0031] In the embodiment, the telescopic rod is connected between the mounting plate 81 and the corresponding inner wall of the box body 3, and is arranged in parallel between the output shaft of the electric push rod 4. When the electric push rod 4 drives the shell 5 to move left and right in the box body 3, the telescopic rod can be contracted or expanded with the shell 5, thereby preventing the shell 5 from being affected and supporting and fixing the shell 5.

[0032] In the embodiment, the dust removal pipe 19 is connected with the exhaust fan through a hose, wherein the top end of the dust removal pipe 19 is inclined towards the polishing roller 2, and the bottom end of the dust removal pipe 19 is fixed at the center of the circular plate 10, and the top end of the dust removal pipe 19 is lower than the top end of the polishing roller 2.

[0033] In the embodiment, a polygonal fixed channel 21 is arranged at the bottom end of the polishing roller 2, wherein a connecting rod 22 extending into the fixed channel 21 is arranged on the output shaft of the polishing motor 1, and a plurality of filling blocks 23 are arranged in the fixed channel 21 at the top end of the connecting rod 22, and the polishing roller 2 is provided with a mounting hole 24, wherein a bolt 25 is arranged in the mounting hole 24, the bolt 25 passes through the filling block 23 and is screwed with the connecting rod 22, and a liquid storage cavity is arranged in the side wall of the polishing roller 2.

[0034] When the length of the polishing roller 2 extending into the opening of the magnetic head shell 6 needs to be adjusted, the height of the top end of the polishing roller 2 can be changed by filling a corresponding number of filling blocks 23 in the fixed channel 21 in advance, then buckling the fixed channel 21 on the connecting rod 22, and screwing the bolt 25 in the mounting hole 24 with the connecting rod 22, so that the length of the polishing roller 2 extending into the magnetic head shell 6 meets the production requirements. Since the polygonal fixed channel 21 can lock the connecting rod 22, the problem of the polishing roller 2 slipping on the connecting rod 22 and affecting the polishing work on the inner wall of the magnetic head shell 6 is prevented. The cooling liquid in the liquid storage cavity can cool the outer wall of the polishing roller 2, so that the polishing roller 2 can cool the heat generated during polishing of the magnetic head shell 6, preventing the long-term high temperature from affecting its use.

[0035] In this embodiment, a heat dissipation layer is arranged on the bottom wall of the shell 5 between the two groups of support plates 7. The outer wall of the shell 5 is provided with a heat dissipation strip opposite the heat dissipation layer. The heat dissipation layer covers the polishing end face of the magnetic head shell 6, so that it can absorb the heat of the side wall of the polishing part of the magnetic head shell 6, and the heat is dissipated by the heat dissipation layer and the heat dissipation strip, preventing the polishing part of the magnetic head shell 6 from being in a high temperature state and affecting its processing.

[0036] The working principle of the present application is as follows: when the magnetic head shell 6 needs to be placed in the shell 5 for processing, the driving motor 16 drives the gear 13 and the rotating shaft 14 to rotate the gear teeth 12, so that the gear teeth 12 drive the circular plate 10 to rotate above the cylinder 9, and the circular plate 10 drives the polishing motor 1 and the polishing roller 2 to rotate to the middle between the front and rear ends of the shell 5, so that the polishing roller 2 has a large gap with the front and rear walls of the shell 5 to facilitate the insertion of the magnetic head shell 6 into the shell 5 and buckling on the polishing roller 2;

[0037] When the bottom opening of the magnetic head shell 6 is inserted into the shell 5 for fixation, the support plates 7 can support the left and right ends of the magnetic head shell 6 to prevent it from being pulled out of the bottom opening of the shell 5, and the two groups of locking blocks 84 are slid into the bottom opening of the magnetic head shell 6, while the locking motor 83 drives the reversible lead screw 82 to rotate to move the locking blocks 84 towards the inner wall of the magnetic head shell 6, so as to lock and fix the side wall of the magnetic head shell 6 in the shell 5 to prevent it from slipping out during processing;

[0038] Then the driving motor 16 drives the polishing roller 2 to rotate 90 degrees through the gear 13, the circular plate 10 and other components, and contacts the polishing starting end of the inner wall of the magnetic head shell 6. Then the polishing motor 1 drives the polishing roller 2 to rotate to polish the inner wall of the magnetic head shell 6, and the electric push rod 4 drives the shell 5 to move the magnetic head shell 6 to the left, so that the polishing roller 2 can completely cover the entire polishing surface of the inner wall of the magnetic head shell 6. Then the electric push rod 4 and the shell 5 drive the magnetic head shell 6 to move back and forth left and right, so that the polishing roller 2 can fully polish the inner wall of the magnetic head shell 6;

[0039] When the other inner wall of the magnetic head shell 6 needs to be polished, the driving motor 16 drives the polishing roller 2 to rotate 180 degrees through the gear 13, the circular plate 10 and other components, and then the polishing roller 2 contacts the polishing starting end of the other inner wall of the magnetic head shell 6, and then the above steps are repeated to polish the other inner wall.

[0040] The above has carried on the detailed explanation to the present application, but the content described is only the preferred embodiment of the present application, cannot be considered for limiting the implementation range of the present application. All equivalent changes and improvements made according to the scope of the present application should still belong to the patent coverage range of the present application.
