Description

Technical Field

[0001] The present invention relates to the field of magnetic heads, and in particular to a grinding device for a magnetic head housing. Background Art

[0002] A magnetic head refers to a component that reads data on a magnetic medium through the magnetic principle. Common magnetic heads include hard disk magnetic heads, tape recorder magnetic heads, etc. On one side of the housing of the magnetic head of the existing banknote detector, there is an opening for fixing the original components of the magnetic head of the banknote detector, and on the other side of the shielding cover, there is a through hole through which banknote signals are collected.

[0003] During the production of magnetic heads, the magnetic head housing needs to be ground. Patent Application No.: 201721782236.0 discloses a grinding device for producing magnetic heads. After the magnetic head is produced, the magnetic head to be ground is placed between the upper fixing block and the lower fixing block and locked by a locking mechanism. Then, the rotating rod is rotated, and the movement of the moving box is driven by the rotation of the threaded rod, so as to realize the movement of the grinding disc. After that, the magnetic head is ground by the grinding disc. However, the grinding efficiency of such a grinding device for magnetic heads is low. The magnetic head needs to be fixed before grinding, and after grinding, the magnetic head needs to be removed to perform the next grinding, resulting in low grinding efficiency.

[0004] The present invention is research and proposed in view of the deficiencies of the prior art. Summary of the Invention

[0005] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art and provide a grinding device for a magnetic head housing.

[0006] The present invention can be realized by the following technical solutions:

[0007] The present invention discloses a polishing device for a magnetic head housing, which comprises a frame. A rotating motor is fixed on the frame, and a turntable is fixed at the output end of the rotating motor. A plurality of rotating shafts rotatably connected to the turntable are evenly arranged on the turntable. Through holes are arranged on the turntable at the bottom of each rotating shaft. A positioning block is further fixed at the bottom of each rotating shaft, and a positioning plate is fixed on the positioning block. A torsion spring is also fixed between the positioning block and the turntable. Fixed blocks are fixed at the tops of the rotating shafts. A sliding plate is further arranged above the turntable, and a plurality of sliding rods are fixed on the frame above the turntable. Slide tubes are arranged at the corresponding positions of the sliding plate and the sliding rods. The sliding rods pass through the slide tubes and are slidably connected to the slide tubes. Polishing blocks are symmetrically and fixedly arranged on both sides below the sliding plate. The sliding plate is driven by a polishing motor to move on the sliding rods. A limiting plate used in cooperation with the positioning plate is fixed on the frame on one side of the turntable. Two polishing motors are fixed on the frame at the position of the limiting plate. The two polishing motors are symmetrically arranged on the frame on both sides of the turntable, and polishing wheels are fixed at the output ends of the polishing motors. Fix the magnetic head housing to be polished to the fixed block. Insert the fixed block into the interior of the housing to fix the housing on the fixed block. After the housing is fixed, drive the turntable to rotate by a certain angle through the rotating motor. The housing rotates with the turntable to between the two polishing blocks. Drive the rotating block to rotate through the polishing motor. When the rotating block rotates, the pull rod rotates with the rotating block. The pull rod pushes the sliding plate to move back and forth on the sliding rod through the push plate, so as to realize polishing the two side surfaces of the housing. And then fix the housing on the next fixed block again. Drive the turntable to rotate again through the rotating motor. When the turntable rotates, after the positioning plate at the position of the polished two side surfaces of the housing contacts the limiting plate, it pushes the rotating shaft to rotate. After the rotating shaft rotates 90 degrees, the housing passes between the two polishing wheels. The high-speed rotating polishing wheels contact the other two side surfaces of the housing to polish the housing, so as to realize polishing the other two side surfaces of the housing. After the polished housing rotates with the turntable and the positioning plate separates from the limiting plate, due to the action of the torsion spring, the rotating shaft rotates back to the initial state. After the housing reaches the specified position, take down the polished housing and place the housing to be polished again. By operating in a cycle, this device can polish the four side surfaces of the housing and place the magnetic head housings to be polished one by one while polishing, greatly improving the polishing efficiency of the magnetic head.

[0008] Preferably, avoidance holes are arranged on the turntable on one side of the positioning plate.

[0009] Preferably, positioning rods used in cooperation with the positioning plate are arranged in the through holes. By arranging the positioning rods to block the positioning plate, it can ensure that the housing passes between the two polishing blocks.

[0010] Preferably, a push rod is further fixed on the sliding plate. The polishing motor is fixed on the frame, and a rotating block is fixed at the output end of the polishing motor. A pull rod is further fixed on the rotating block, and the pull rod is connected to the push rod through a push plate.

[0011] Preferably, a limiting rod is further fixed on the frame at the position of the sliding plate, and a limiting strip is further fixed on the frame between the grinding wheels. By arranging the limiting rod and the limiting strip to block, it is avoided that the outer shell is separated from the fixed block during grinding.

[0012] The present invention has the following advantages compared with the existing technology:

[0013] This device can realize grinding the four sides of the outer shell, and while grinding, placing the magnetic head outer shells to be ground one by one, greatly improving the grinding efficiency of the magnetic head. Description of the Drawings

Fixed blocks 10 are fixed at the top of the rotating shafts 4. A slide plate 12 is also arranged above the turntable 3. Multiple slide bars 11 are fixed on the frame 1 above the turntable 3. Slide tubes 14 are arranged at the corresponding positions of the slide plate 12 and the slide bars 11. The slide bars 11 pass through the slide tubes 14 and are slidably connected to the slide tubes 14. Grinding blocks 13 are symmetrically fixed on both sides below the slide plate 12. The slide plate 12 is driven by a grinding motor 16 to move on the slide bars 11. A limiting plate 20 used in cooperation with the positioning plate 7 is fixed on the frame 1 on one side of the turntable 3. Two polishing motors 23 are fixed on the frame 1 at the position of the limiting plate 20. The two polishing motors 23 are symmetrically arranged on the frame 1 on both sides of the turntable 3. Grinding wheels 24 are fixed at the output ends of the polishing motors 23. Fix the magnetic head housing to be ground with the fixed block 10. Insert the fixed block 10 into the interior of the housing to fix the housing on the fixed block 10. After the housing is fixed, drive the turntable 3 to rotate a certain angle by the rotating motor 2. The housing rotates with the turntable 3 to between the two grinding blocks 13. Drive the rotating block 17 to rotate by the grinding motor 16. When the rotating block 17 rotates, the pull rod 18 rotates with the rotating block 17.
