[0022] When disassembling and replacing the spring 6 between the polishing table 3 and the polishing layer 4, first adjust the rotation of the bidirectional threaded screw 9 by adjusting the knob. Then, the rotation of the bidirectional threaded screw 9 drives the two sliding blocks 10 to move the two limiting sliders 11 closer to each other and release the limitation of the two limiting blocks 7, so that the polishing layer 4 can be removed from the polishing table 3. This facilitates the timely disassembly and replacement of the spring 6 between the two limiting seats 5 set on the bottom wall of the polishing layer 4 and the top wall of the polishing table 3. This structure can disassemble and replace the spring 6 set between the polishing table 3 and the polishing layer 4, improving the practicality of the device.

[0023] As a further implementation of this embodiment, such as Figures 1-4 As shown, connecting holes 19 are provided on both sides of the base 1. Then, a connecting block 17 is provided on both sides of the bottom of the polishing table 3. Connecting bolts 18 are provided on the surface of the connecting block 17 to abut against the connecting holes 19. At the same time, a movable frame 13 is provided on the upper surface of the base 1 and on one side of the polishing table 3. A limit pin 14 is provided on the movable frame 13. Then, a mounting table 15 is provided on the upper surface of the base 1 and on the other side of the polishing table 3. A chuck 16 is provided on the mounting table 15. An electric push rod 12 is provided on the upper surface of both ends of the base 1. The free ends of the two electric push rods 12 are respectively connected to the movable frame 13 and the mounting table 15. The positions of the movable frame 13 and the mounting table 15 can be pushed and adjusted by the electric push rods 12. Two limit rods 2 are symmetrically fixed on the upper surface of the base 1. The two limit rods 2 slide through the movable frame 13, the polishing table 3 and the mounting table 15 in sequence, making the movable frame 13, the polishing table 3 and the mounting table 15 more stable when moving and adjusting.

[0024] In use, first adjust the position of the polishing table 3, then rotate the connecting bolt 18 so that one end of the connecting bolt 18 abuts against the connecting hole 19, thereby limiting and fixing the polishing table 3. Then, adjust the position of the movable frame 13 and the mounting table 15 by using two electric push rods 12 so that the camshaft is positioned between the chuck 16 and the limiting pin 14. Then, drive the chuck 16 by the motor, and drive the camshaft to rotate. Under the action of the spring 6, the polishing layer 4 always adheres to the periphery of the cam and the journal, polishing the entire camshaft.

[0025] Specific working principle:

[0026] When polishing the camshaft, first adjust the position of the polishing table 3, then rotate the connecting bolt 18 so that one end of the connecting bolt 18 abuts against the connecting hole 19, thereby limiting and fixing the polishing table 3. Next, adjust the position of the movable frame 13 and the mounting table 15 by using two electric push rods 12, so that the camshaft is positioned between the chuck 16 and the limiting pin 14. Then, the motor drives the chuck 16, which in turn drives the camshaft to rotate. Under the action of the spring 6, the polishing layer 4 always adheres to the periphery of the cam and the journal, polishing the camshaft. At the same time, the two electric push rods 12 can be used to polish the upper part of the polishing layer 4. The position of the camshaft is adjusted to polish multiple parts of the camshaft. During long-term use, the spring 6 deforms, making it difficult for the polished layer 4 to fit well with the camshaft. First, the double-sided threaded screw 9 is rotated by adjusting the knob. Then, the rotating double-sided threaded screw 9 drives the two sliding blocks 10 to move the two limit sliders 11 closer to each other and release the limit of the two limit blocks 7. The polished layer 4 is then removed from the polishing table 3, which facilitates the timely removal and replacement of the spring 6 between the two limit seats 5 set on the bottom wall of the polished layer 4 and the top wall of the polishing table 3, thus avoiding affecting the polishing of the camshaft.
