By arranging the support member 4 and the positioning assembly on the base 3, it can be ensured that the relative positions of the base plate and the camshaft cover remain unchanged during the engraving process of the engraving mechanism 2, and the movement of the engraving member 13 is constrained by the limit assembly, so that when the engraving member 13 is engraving the camshaft cover, the quality of the engraved serial number is guaranteed.

[0032] The limiting assembly includes a guide sleeve 12 for guiding the movement trajectory of the marking member 13. The marking member 13 is sleeved in the guide sleeve 12. The marking member 13 is used to move along the axial direction of the guide sleeve 12 to mark the camshaft cover. The marking member 13 is limited by the guide sleeve 12, which has a simple structure, good limiting effect, and is easy to assemble.

[0033] The limiting assembly includes a limiting pin 9, a limiting groove 10 extending along the movement direction of the marking member 13 is provided on the guide sleeve 12, the limiting pin 9 is arranged on the marking member 13, the limiting pin 9 is inserted into the limiting groove 10, the limiting groove 10 has a first end close to the base 3 and a second end away from the base 3, when one end of the limiting pin 9 reaches the first end, the marking member 13 is located at the engraving position, and when one end of the limiting pin 9 reaches the second end, the marking member 13 is located at the lifting position. By limiting the movement distance of the marking member 13 by the limiting pin 9 and the limiting groove 10, the marking member 13 can be better switched between the lifting position and the engraving position, ensuring that the marking member 13 is beautiful and uniform when engraving. In this embodiment, two limiting grooves 10 are relatively arranged on the guide sleeve 12, and the two ends of the limiting pin 9 are respectively arranged in the limiting grooves 10. By providing two limiting grooves 10 and arranging both ends of the limiting pin 9 in the limiting grooves 10, the limiting effect on the engraved member 13 can be enhanced, and the limiting pin 9 can be prevented from slipping out of the limiting groove 10, causing the limiting groove 10 to fail to limit the engraved member 13. At the same time, by providing the limiting grooves 10 and the limiting pin 9, the engraved member 13 can be prevented from flying away from the engraving position after engraving, thereby injuring the operator.

[0034] In detail, the engraved number piece 13 is a character code, which is in the shape of a long strip, and a character number for engraving is arranged on the first end of the character code, and a knocking block for knocking is arranged on the second end of the character code. By setting the knocking block, the contact area between the hammer and the character code can be increased, thereby increasing the force-bearing surface of the character code away from the end of the engraved character number, so that the first end of the character code obtains a larger impulse for engraving, so as to ensure the engraving effect.
