After the polishing wheel 8 is completely separated from the guide rail 57, the spring 55 is retracted. The spring 55 pushes the upper frame plate 53, the storage position 56 and the guide rail 57 to reset, so as to prevent the polishing wheel 8 from contacting the velvet sleeve 63 when it is reinstalled, so that the polishing equipment can immediately apply polishing liquid to it when the polishing wheel 8 is replaced; a clamping assembly 13 is installed on the upper side of the seat body 11, and the clamping assembly 13 is composed of a motor, a positive and negative threaded screw, two thread sleeves, two clamping plates and two supporting plates.

The liquid storage tank 65 is composed of a lower liquid cylinder and an upper cover. Through this arrangement, the staff can replenish the liquid storage tank 65.

[0018] Workflow: The automatic replacement operation of the polishing wheel 8 of the automobile sheet metal stamping polishing equipment is as follows. Note 1: All electrical components of this equipment are powered by an external power supply, and the operation of all electrical components is uniformly regulated by the control host 9; Note 2: By starting the motor of the control clamping assembly 13, it drives the positive and negative threaded screws to rotate. The rotation of the screw will drive the thread sleeves and the clamps on both sides to approach each other, thereby achieving a firm clamping of the automobile sheet metal placed on the pallet, preparing for subsequent polishing operations; Automatic installation operation: The control host 9 will regulate the actions of various equipment throughout the process. First, the control manipulator 2 is controlled to accurately drive the drive unit 3 and the clamping sleeve module 4 to move to the corresponding clamping head to be installed with the polishing wheel 8 When the locking cam 76 is in the unlocking state, the locking cam 76 is in the unlocking state, and the locking cam 76 is in the unlocking state. The electric push rod 33 contracts, driving the transmission member 34 to move upward. The upward movement of the transmission member 34 will drive the collar 49 and each connecting rod 46 to rise synchronously. The upward movement of each connecting rod 46 will push each connecting bar 42 and the connecting plate 43 to move upward. The upward movement of the connecting plate 43 cooperates with the folding hose 44 to exhaust air from each exhaust channel 415. Under the action of exhaust, the rubber sheet 768 of each latch part 76 is affected by the change of air pressure, driving the extension rod 767 to move upward into the exhaust channel 415. The suction force generated by the exhaust makes the card sleeve module 4 and the card head module 7 achieve a tighter initial connection. On the other hand, the upward movement of the connecting rod 46 will also drive each sleeve block 47 and the magnet 48 to rise. After the movement, it is aligned with the card track 417, and is also aligned with the magnetic block 773 of the card pin portion 77. At this time, due to the magnetic principle of opposites attracting each other, the magnet 48 will produce a magnetic attraction on the magnetic block 773, so that each magnetic block 773 drives each card rod 771 to move and insert into the card track 417. At the same time, the limit block 772 that moves with the card rod 771 will squeeze the spring body 774, causing the spring body 774 to shrink. Through this ingenious setting, the latch portion 76 can be effectively limited, and the connection between the card sleeve module 4 and the card head module 7 can be further stabilized. Through the above multiple connections, the card head module 7 can be prevented from falling off when rotating with the card sleeve module 4, and finally the automatic installation of the polishing wheel 8 is successfully completed;Automatic disassembly operation: The control host 9 will regulate the actions of various devices throughout the whole process. First, the electric push rods 33 are controlled to reset and extend, driving the transmission member 34 to move downward. The downward movement of the transmission member 34 will drive the collar 49 and the linkage rods 46 to reset and move downward synchronously. The downward movement of the linkage rods 46 will push the linkage bars 42 and the linkage plates 43 to move downward. The downward movement of the linkage plates 43 will discharge the extracted air through the exhaust duct 415, so that the extension rod 767 and the rubber sheet 768 will reset and move downward; on the other hand, it will drive the sleeve blocks 47 and the magnet 48 to move downward, so that the magnet 48 is no longer aligned with the magnetic block 773. After losing the magnetic attraction, the magnetic block 773, the clamping rod 771 and the limit block 772 will be reset by the expanded spring body 774 The locking nut 77 is pushed back to return to the latch 76 so that the locking nut 77 no longer engages the latch 76. Through the above operation, the connection between the ferrule module 4 and the clamping head module 7 is disconnected. At this time, the ferrule module 4 is controlled to move upward to disconnect the ferrule module 4 from the clamping head module 7, and the automatic disassembly of the polishing wheel 8 can be completed. Through the combination of the automatic installation operation and the automatic disassembly operation, the polishing equipment can automatically replace the polishing wheels 8 of different diameters according to the needs, so as to adaptively polish the automobile stamping parts with complex shapes, thereby solving the problem that the replacement of the polishing wheel 8 of the existing polishing equipment generally requires manual operation, which is neither convenient nor easy to efficiently and automatically perform polishing on the automobile stamping parts with complex shapes.Automatic smearing operation: During the automatic installation operation, the card sleeve module 4 will move downward to apply pressure to the card head module 7, so that it applies a downward force to the upper frame plate 53 through the rail groove 74 and the guide rail 57, causing the spring 55 to contract. At the same time, the polishing wheel 8 is adjusted to the same horizontal height as the top of the velvet sleeve 63 as the card sleeve module 7 moves. When the polishing wheel 8 is installed, the control host 9 issues a command, and the manipulator 2 pulls the card sleeve module 7 and the polishing wheel 8 to the left through the card sleeve module 4, so that it is separated from the storage position 56 of the storage rack 5. During the movement, the polishing wheel 8 contacts the velvet sleeve 63 and drives the velvet sleeve 63 and the roller 62 to rotate together, so that the velvet sleeve 63 evenly smears the polishing liquid absorbed from the liquid shell 61 on the lower surface of the polishing wheel 8, ensuring that the polishing wheel 8 can be quickly prepared and put into the polishing process of the automobile stamping parts. When the polishing wheel 8 is completely free from the restraint of the guide rail 57, the spring 55 releases The stored energy is released to push the upper frame plate 53, the storage position 56 and the guide rail 57 to return to the initial height position, so that the polishing wheel 8 will not contact the velvet sleeve 63 when it is reinstalled, and the velvet sleeve 63 will not apply polishing liquid to the reinstalled polishing wheel 8. In addition, the upper and lower liquid level probes 64 will continuously monitor the liquid level of the polishing liquid in the liquid shell 61. Once it is detected that the liquid level drops below the set position of the lower liquid level probe 64, the control host 9 will automatically start the electric control valve 67 to open, so that the polishing liquid in the liquid storage tank 65 flows into the liquid shell 61 through the liquid replenishing pipe 66 for replenishment, until the liquid level rises to the set position of the upper liquid level probe 64. At this time, the control host 9 will close the electric control valve 67 and stop replenishing liquid into the liquid shell 61, so that the polishing equipment can immediately apply polishing liquid to the polishing wheel 8 when replacing it, so that the polishing wheel 8 can be immediately put into the polishing operation, avoiding the prolonged preparation time of the polishing wheel 8 due to the failure to apply polishing liquid in time, which affects the polishing efficiency. ;
