[0034] The supporting base 1 is also provided with an upper driving device 8, the output end of the upper driving device 8 is connected to an upper placing frame 9 which can move up and down relative to the positioning mounting frame 2, and the upper placing frame 9 is installed with a pushing driving device 10. The output end of the pushing driving device 10 is connected to a pushing frame 11 which can move forward and backward relative to the upper placing frame 9, and the pushing frame 11 is provided with at least two groups of pushing rod groups corresponding to at least two groups of positioning components respectively. The upper placing frame 9 is also provided with an upper opening 12 that can give way to the positioning pressure rod assembly.

[0035] In this embodiment, the turning drive device 3 can be a rotary motor; the positioning drive device 6, the lifting drive device 8 and the pushing drive device 10 can be cylinders. Figures 1-4 As shown, the positioning mounting frame 2 may include two symmetrically arranged positioning mounting plates, the flip drive device 3 is mounted on one positioning mounting plate, one end of the flip frame 4 is connected to the flip drive device 3, and the other end of the flip frame 4 is rotatably connected to the other positioning mounting plate via a bearing 17. Figure 8 As shown, the push rack 11 has a push connecting plate 28 that can be connected to the push drive device 10. In order to improve the stability of the upper placement rack 9 moving up and down, the upper drive device 8 can be provided with two, such as Figure 6 shown.

[0036] Take the example of two sets of positioning assemblies as an example: in the zero position state, the turning frame 4 is rotated to a state horizontal to the supporting base 1 through the turning drive device 3, and the positioning seat 5 is located at the top of the turning frame 4, and the positioning pressure rod assembly is driven to separate from the top area of ​​the positioning seat 5 by the positioning drive device 6; then the two cylinder heads are respectively buckled upside down (the top of the cylinder head is at the bottom end, and the bottom of the cylinder head is at the top end) on the two positioning seats 5, and then, the positioning drive device 6 is started to drive the positioning pressure rod assembly to press the cylinder head on the positioning seat 5 to accept the lettering operation; after the lettering is completed, the turning drive device is turned on again. Set 3 to drive the turning frame 4 to turn 180°. At this time, the positioning seat 5 is located at the bottom end of the turning frame 4, and the cylinder head is in an upright state. At the same time, start the upper driving device 8 to drive the upper placement frame 9 to move up until it contacts the bottom of the cylinder head; then reset the positioning driving device 6 to disengage the positioning pressure rod assembly from the pressing effect on the cylinder head. At this time, the upper opening 12 can be used to make way for the moving trajectory of the positioning pressure rod assembly; finally, start the pushing driving device 10 to drive the pushing frame 11 to move forward, and the pushing rod group can push the cylinder head that has completed the engraving operation to the next conveying station.

[0037] In order to realize the pressing effect of the positioning pressure rod assembly on the cylinder head, preferably, the positioning pressure rod assembly includes a fixing seat 13, a pressure rod 7 and two connecting rods 14;

[0038] The fixing seat 13 is installed on the positioning drive device 6, and the bottom end of the pressure rod 7 is hinged to the output end of the positioning drive device 6;

[0039] One end of the two connecting rods 14 is hinged to both sides of the middle area of ​​the fixing seat 13 , and the other end of the two connecting rods 14 is hinged to both sides of the middle area of ​​the pressure rod 7 .

Figure 3 shown.

[0041] In order to achieve the connection between the fixing seat 13 and the two connecting rods 14 , a fixing connection protrusion 29 is provided in the middle area of ​​the fixing seat 13 .

[0044] Preferably, the pushing frame 11 is provided with a cleaning brush 18 located between the two pushing rods 16 in the same pushing rod group.

[0045] During use, some waste chips will fall onto the upper placement rack 9 after engraving. When the pushing rack 11 moves forward to push the cylinder head, the cleaning brush 18 can sweep the waste chips from the upper through-port 12 to the support base 1, thus preventing the waste chips from causing accidental wear on the cylinder head.
