Description

Technical Field

[0001] This utility model relates to a magnetic polishing production line. Background Technology

[0002] Magnetic polishing works by utilizing a strong and stable magnetic field to generate a powerful magnetic effect, allowing the magnetic steel needle to perform integrated, multi-angle grinding on the workpiece. This method can quickly remove rust, dead corners, burrs, and oxide films, and can also effectively handle workpieces with complex shapes, multiple holes and gaps, and internal and external threads without damaging the workpiece surface or affecting its precision. It is also suitable for grinding small, irregularly shaped parts and irregularly shaped components. It is simple to operate, low in cost, fast, and has a wide range of applications.

[0003] The existing magnetic polishing process involves manually transporting the magnetic polishing barrel onto the magnetic polishing machine. After the polishing is complete, the barrel is removed from the machine by another person, and the items inside are then manually removed for further processing. In this process, most of the work is done manually, which is time-consuming and labor-intensive. In addition, because the magnetic polishing machine has a strong magnetic force, it is quite difficult to remove the barrel from the machine. Utility Model Content

[0004] The purpose of this invention is to provide a magnetic polishing production line that can perform fully automatic magnetic polishing and post-processing on parts, which is efficient and convenient.

The picking block 11-3 is rotatably set on the side wall of the magnetic throwing impact through the rotating engagement of the rotating rod 11-3-1 and the rotating groove. The picking rod returns to a horizontal state after rotation under the elastic force of the torsion spring 11-4. The end of the picking block 11-3 facing the inside of the magnetic throwing basin 1-2-2 can contact the card plate 11-2 after the picking block 11-3 rotates, and drive the groove to disengage from the snap fastener 11-1.

The lower end of the leveling scraper 10-2 and the second conveyor belt 7-1 form a leveling space for objects to pass through sequentially.

[0062] The lower end of the leveling scraper 10-2 may also be equipped with a rubber belt. Because the magnetic objects piled up due to their magnetic properties are obstructed by the leveling scraper 10-2 under the drive of the second conveyor belt 7-1, they will pass through the leveling space due to the obstruction. The magnetic objects passing through the leveling space can be scraped by the rubber belt and evenly spread on the second conveyor belt 7-1, which is convenient for subsequent processing.

[0067] Below the second conveyor belt 7-1 is a water collection tank 17 for collecting the flowing water. It can collect the water sprayed from the spray assembly 4 and the water blown out of the sprayed objects by the drying assembly 5, thus avoiding environmental pollution.

[0068] The lower ends of the first conveyor frame 2, the second conveyor frame 7, the transport support 8-1, and the cleaning frame 13 are all fixedly equipped with support legs.

[0069] The working principle of this utility model is as follows: The transport drive device 8-3 in the transport assembly 8 drives the transport roller 8-2 located on the transport bracket 8-1 to rotate. The rotating transport roller 8-2 drives the magnetic throwing barrel 1-2 located on the transport roller 8-2 to move towards the first conveyor frame 2. Under the drive of the transport roller 8-2, the magnetic throwing barrel 1-2 enters the transfer platform 8-5. After the sensing device 8-4 on the transfer platform 8-5 senses the magnetic throwing barrel 1-2, it drives the transport drive device 8-3 to stop driving the transport roller 8-2 through a signal connection. At this time, the push plate 9-3 pushes the magnetic throwing barrel 1-2 downward under the drive of the drive device 9-4, pushing it towards the first conveyor frame 2. Baffle 9-1, together with the second baffle 9-2, positions the magnetic throwing barrel 1-2 in the positioning space. The robot arm 16 then clamps and transfers the magnetic throwing barrel 1-2 in the positioning space to the magnetic throwing machine 1-1. The moment the magnetic throwing barrel 1-2 in the positioning space is clamped and moved by the robot arm 16, the sensing device 8-4 drives the transport drive device 8-3 to continue driving the transport roller 8-2 through a signal connection, transporting the next magnetic throwing barrel 1-2 to the transfer platform 8-5. Then the robot arm 16 repeats the clamping and transporting of the magnetic throwing barrel 1-2. When there is no magnetic throwing barrel 1-2 to be clamped and transported, the transport drive device 8-3 stops transporting.

[0070] After all the magnetic polishing barrels 1-2 are placed on the magnetic polishing machine 1-1, the objects to be magnetically polished are placed into the magnetic polishing basins 1-2-2 within the magnetic polishing barrels 1-2. The magnetic polishing machine 1-1 then begins to magnetically polish the objects in the magnetic polishing barrels 1-2. After the magnetic polishing is completed, the telescopic drive device 12-1 in the drive assembly 12 on the magnetic polishing machine 1-1 drives the fixed plate 12-2 and the first and second push blocks 12-4 located on the fixed plate 12-2 to rise and fall. The rising and falling first and second push blocks 12-4 respectively drive the corresponding side pick blocks 11-3 to rotate. The rotating pick blocks 11-3 press against the clamping plate 11. -2 and drive the buckle 11-1 to disengage from the slot, the first flap 1-2-2-1 and the second flap 1-2-2-2 rotate, so that the object in the magnetic polishing basin 1-2-2 falls onto the drain mesh 1-2-1-1 in the discharge basin 1-2-1. The robot arm 16 pulls open the discharge gate 3 at the discharge port, so that the object on the drain mesh 1-2-1-1 falls from the discharge port onto the first conveyor belt 2-1. The first drive device 2-2 drives the first conveyor belt 2-1 to rotate, and the first conveyor belt 2-1 transports the magnetically polished object toward the discharge assembly line.

[0071] The height difference between the first conveyor belt 2-1 and the second conveyor belt 7-1 allows the magnetically polished objects on the first conveyor belt 2-1 to be transferred to the second conveyor belt 7-1. The second drive device 7-2 drives the second conveyor belt 7-1 to rotate, carrying the magnetically polished objects towards the spray assembly 4. The compressor 4-1 in the spray assembly 4 absorbs water from the water tank at its inlet, and after compression by the compressor 4-1, the water is discharged from its outlet. The water flow enters the spray head 4-2 from the outlet, and the spray head 4-2 sprays the water onto the objects on the second conveyor belt 7-1. On the object on 1; as the second conveyor belt 7-1 rotates, the second conveyor belt 7-1 transports the sprayed object to the drying assembly 5. The powerful blower 5-3 in the drying assembly 5 squeezes the air force into the dewatering drying air knife 5-2, and then the dewatering drying air knife 5-2 blows the air evenly on the sprayed object to dry it. The dried object is then transported by the second conveyor belt 7-1 into the demagnetizing assembly 6. The cabinet demagnetizer 6-2 in the demagnetizing assembly 6 demagnetizes the dried object. The demagnetized object is then transported by the second conveyor belt 7-1 into the collection box 15.

[0072] After all the objects from the magnetic polishing barrel 1-2 have entered the collection box 15, the robotic arm 16 transfers the magnetic polishing barrel 1-2 located on the magnetic polishing machine 1-1 to the placement slot of the upper boss of the cleaning rack 13. Then, the robotic arm 16 uses the magnetic attraction of the first magnetic block and the second magnetic block 16-1 and the sliding engagement of the first magnetic block with the corresponding first sliding groove and the second sliding groove to scrape the objects remaining on the drain screen 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. After the above processing steps, they enter the collection box 15.

[0073] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
