[0022] The present invention achieves the effect of quickly removing the broken grinding part by setting the cooperation of the second spring telescopic rod and the fixing part and other structures. The rotation of the rotating shaft drives the L-shaped movable part to move upward, and the upward movement of the L-shaped movable part drives the T-shaped plate to rotate. The T-shaped plate does not interfere with one of the grinding parts, and moves so as not to be clamped with the processing shell. One of the grinding parts continues to move upward so as not to be clamped with the processing shell at all, thereby facilitating the replacement of the grinding part.

[0023] The present invention realizes the effect of quickly replacing the grinding part by setting the coordination of structures such as the connecting movable part and the movable plate. The connecting movable part moves downward until it contacts the movable plate, and the two groups of movable plates move away from each other, thereby releasing the clamping connection with the second grinding part, allowing the second grinding part to slide along the slope at the bottom of the processing shell, so that the second grinding part is clamped with the processing shell, and the fixed part is clamped with the second grinding part, thereby speeding up the time for replacing the grinding part, thereby avoiding the situation where a large amount of time consumed in replacing the grinding part leads to prolonged grinding time of the belt electrode and reduced work efficiency.

When different positions of the electrode body 3 are polished, the corrugated plates 501 at different angles are contracted, and the first spring telescopic rod 502 at the position that does not conflict drives the corrugated plate 501 to reset, thereby achieving the effect of blocking the debris generated when polishing the electrode and preventing the broken polishing piece from causing damage to other electrodes. Through the cooperation of the mounting plate 801 and the fourth spring telescopic rod 802, one of the polishing pieces 605 continues to move upward The movement makes it completely uncoupled from the processing shell 4. At this time, one of the grinding pieces 605 contacts the arc piece 803, causing the arc pieces 803 on both sides to move away from each other, so that one of the grinding pieces 605 is moved out of the inner cavity of the processing shell 4. The staff holds the handle and pulls the fixing piece 609 to release the connection with the one of the grinding pieces 605, and takes out the one of the grinding pieces 605, so as to facilitate the replacement of the grinding piece. The arc-shaped design of the arc piece 803 makes the one of the grinding pieces 605 better contact the arc piece 803, causing the arc piece 803 to move away from each other.

[0050] The working principle and use process of the present invention:

[0051] When in use, the electrode body 3 is fixed on the surface of the fixing seat 2, and then the device is started to process and grind the electrode. When the electrode is processed and polished, the rectangular plate 503 contacts the electrode fixing seat, so that the corrugated plate 501 and the first spring telescopic rod 502 shrink. When different positions of the electrode body 3 are polished, the corrugated plates 501 at different angles shrink, and the first spring telescopic rod 502 at the position where there is no conflict drives the corrugated plate 501 to reset. When the detector at the bottom of the processing shell 4 detects that one of the polishing parts 605 is broken during polishing, the alarm 10 sounds an alarm to warn the staff, and the drive motor 601 starts automatically. The drive motor 601 drives the worm 602 and the gear 702 to rotate. The rotation of the worm 602 drives the worm wheel 603 to rotate. The rotation of the worm wheel 603 drives the rotating shaft 604 to rotate. The rotation of the rotating shaft 604 drives the L-shaped movable part 6064 to move upward, and the L-shaped movable part 6064 The upward movement drives the T-shaped plate 6062 to rotate, so that the arc spring telescopic rod 6063 is contracted, so that the T-shaped plate 6062 does not interfere with the first grinding piece 605. At the same time, the gear 702 rotates to drive the toothed plate 701 to move. The toothed plate 701 moves to drive the movable plate 607, the second spring telescopic rod 608, the fixing piece 609 and the first grinding piece 605 to move, so that the first grinding piece 605 moves so as not to be engaged with the processing shell 4. The first grinding piece 605 continues to move upward so as not to be engaged with the processing shell 4 at all. At this time, the first grinding piece 605 interferes with the arc-shaped piece 803, so that the arc-shaped pieces 803 on both sides move back to each other, so that the first grinding piece 605 moves out of the inner cavity of the processing shell 4. The staff holds the handle and pulls the fixing piece 609 to release the engagement with the first grinding piece 605, and takes out the first grinding piece 605, so as to facilitate the replacement of the grinding piece.

[0052] When the rotating shaft 604 rotates, the connecting movable member 703 is driven to move. When the first grinding member 605 is completely not engaged with the processing shell 4, the connecting movable member 703 moves downward until it conflicts with the movable plate 705. The connecting movable member 703 continues to move downward, so that the connecting movable member 703 continues to conflict with the movable plate 705, so that the two groups of movable plates 705 move back to back, and the movable plate 705 squeezes the third spring telescopic rod 704, so that the third spring telescopic rod 704 contracts, and the two groups of movable plates 705 move back to back to release the engagement with the second grinding member 706, so that the second grinding member 706 slides along the slope at the bottom of the processing shell 4, so that the second grinding member 706 and the processing shell 4 The fixing member 609 is clamped together with the second polishing member 706, and the connecting plug 9 is moved upward, so that the new polishing member is placed in the inner cavity of the processing shell 4 for replacement next time, thereby speeding up the replacement time of the polishing member, and further avoiding the large amount of time consumed in replacing the polishing member, which leads to prolonged grinding of the electrode and reduced work efficiency.
