Description

Technical Field

[0001] The present invention relates to a magnetic polishing production line. Background Art

[0002] The principle of magnetic polishing is to utilize the magnetic field distribution to generate a strong and stable magnetic induction effect, enabling the magnetic steel needles to perform integral and multi-angle full grinding on the workpiece. This method can not only quickly remove rust, dead corners, burrs and oxide films, but also effectively process workpieces with complex shapes, porous seams, internal and external threads, etc., without damaging the surface of the workpiece or affecting its accuracy; it is also applicable to the grinding of small special-shaped parts and irregular parts, with simple operation, low cost, high speed, and wide application range.

[0003] In the existing magnetic polishing process, the magnetic polishing barrel is manually carried to the magnetic polishing machine, and after magnetic polishing is completed, someone manually removes the magnetic polishing barrel from the magnetic polishing machine, and the objects in the magnetic polishing barrel are taken out manually for post-treatment; in this process, most of the work is carried out manually, which is time-consuming and laborious. At the same time, due to the large magnetic force of the magnetic polishing machine, it is difficult to remove the magnetic polishing barrel from the magnetic polishing machine.

[0048] Support legs are fixedly arranged at the lower ends of the above-mentioned first conveyor rack 2, second conveyor rack 7, transportation support 8-1 and material cleaning rack 13.

[0049] The working principle of the present invention: The transportation drive device 8-3 in the transportation assembly 8 drives the transportation roller 8-2 located on the transportation support 8-1 to rotate. The rotating transportation roller 8-2 drives the magnetic polishing barrel 1-2 located on the transportation roller 8-2 to move towards the first conveyor rack 2. The magnetic polishing barrel 1-2 enters the transfer platform 8-5 driven by the transportation roller 8-2. After the induction device 8-4 on the transfer platform 8-5 senses the magnetic polishing barrel 1-2, it drives the transportation drive device 8-3 to stop driving the transportation roller 8-2 through signal connection. At this time, the push plate 9-3 pushes the magnetic polishing barrel 1-2 towards the first baffle 9-1 driven by the pushing drive device 9-4, and then cooperates with the second baffle 9-2 to position the magnetic polishing barrel 1-2 in the positioning space. The manipulator 16 clamps and transfers the magnetic polishing barrel 1-2 located in the positioning space to the magnetic polishing machine 1-1. The moment the magnetic polishing barrel 1-2 located in the positioning space is clamped and taken away by the manipulator 16, the induction device 8-4 drives the transportation drive device 8-3 to continue driving the transportation roller 8-2 through signal connection, and transports the next magnetic polishing barrel 1-2 to the transfer platform 8-5. Then the manipulator 16 repeats the clamping and transportation of the magnetic polishing barrel 1-2. When there is no magnetic polishing barrel 1-2 to be clamped and transported, the transportation drive device 8-3 stops transporting. After all the magnetic polishing barrels 1-2 are placed on the magnetic polishing machine 1-1, the object to be magnetically polished is placed into the magnetic polishing basin 1-2-2 in the magnetic polishing barrel 1-2. The magnetic polishing machine 1-1 starts to magnetically polish the object in the magnetic polishing barrel 1-2. After the magnetic polishing is completed, the telescopic driving device 12-1 in the driving assembly 12 on the magnetic polishing machine 1-1 drives the fixed plate 12-2 and the first and second pushing blocks 12-4 located on the fixed plate 12-2 to move up and down. The first and second pushing blocks 12-4 moving up and down respectively drive the corresponding side picking blocks 11-3 to rotate. The rotating picking blocks 11-3 press against the clamping plate 11-2 and drive the buckle 11-1 to disengage from the clamping fit with the groove. The first flap 1-2-2-1 and the second flap 1-2-2-2 rotate, causing the object in the magnetic polishing basin 1-2-2 to fall onto the water drainage mesh plate 1-2-1-1 in the discharge basin 1-2-1. The manipulator 16 opens the discharge gate plate 3 at the discharge port, so that the object on the water drainage mesh plate 1-2-1-1 falls from the discharge port onto the first conveyor belt 2-1. The first driving device 2-2 drives the first conveyor belt 2-1 to rotate, and the first conveyor belt 2-1 transports the magnetically polished object towards the discharge assembly line; The height difference between the first conveyor belt 2-1 and the second conveyor belt 7-1 can transfer the magnetically polished object on the first conveyor belt 2-1 to the second conveyor belt 7-1. The second driving device 7-2 drives the second conveyor belt 7-1 to rotate. The second conveyor belt 7-1 transports the magnetically polished object towards the spraying assembly 4. The water inlet end of the compressor 4-1 in the spraying assembly 4 absorbs the water in the water tank. After being compressed by the compressor 4-1, the water is discharged from the water outlet end of the compressor 4-1. The water flow enters the spray head 4-2 from the water outlet end, and the spray head 4-2 sprays the water flow onto the object on the second conveyor belt 7-1. As the second conveyor belt 7-1 rotates, the second conveyor belt 7-1 transports the object after spraying to the drying assembly 5. The powerful blower 5-3 in the drying assembly 5 squeezes the wind force into the water removal and drying air knife 5-2, and then the water removal and drying air knife 5-2 evenly dries the object after spraying. The dried object then enters the demagnetization assembly 6 under the transportation of the second conveyor belt 7-1. The cabinet-type demagnetizer 6-2 in the demagnetization assembly 6 demagnetizes the dried object. The demagnetized object then enters the collection box 15 under the transportation of the second conveyor belt 7-1; After all the objects in the magnetic polishing bucket 1-2 enter the collection box 15, the manipulator 16 transfers the magnetic polishing bucket 1-2 on the magnetic polishing machine 1-1 to the placement groove of the convex platform at the upper end of the cleaning rack 13. Then, the manipulator 16 uses the magnetic attraction cooperation between the first magnetic attraction block and the second magnetic attraction block 16-1 on it, as well as the sliding cooperation between the first magnetic attraction block and the corresponding first sliding groove and the second sliding groove, to scrape the objects remaining on the water drainage mesh plate 1-2-1-1 towards the discharge port. The remaining objects flow out of the discharge port and fall onto the second conveyor belt 7-1, and then enter the collection box 15 after the above treatment steps.

It should be understood that the above are only specific embodiments of the present invention and are not used to limit the present invention.
