After reading this description, those skilled in the art can make modifications to the embodiment without creative contribution according to needs, but as long as it is within the utility model All new claims are protected by patent law.

Embodiment: as shown in Figures 1, 2, and 3, the marking device for workpieces includes a marking cylinder 1, a moving plate 2, fixed on the moving plate 2 and connected with the marking cylinder 1 piston rod The marking head mounting column 3, the marking head 4 arranged on the marking head mounting column 3, the guide rod 5 fixed on the moving plate 2, the marking cylinder 1 and the moving plate 2 The fixed plate 6 between them and the guide hole 7 that is located on the fixed plate 6 and the guide rod 5 cooperate; the marking cylinder 1 includes a cylinder body and a piston rod, and the whole marking cylinder is placed horizontally as required, and the cylinder body is fixed. On the machine body, the marking head 4 is fixed on the marking head mounting column 3, and is screwed or welded. The marking head is provided with corresponding marking marks, which are used to contact the surface of the workpiece for corresponding marking. The piston rod of the marking cylinder drives the movable plate 2 to move, and the guide rod 5 is inserted in the guide hole 7 to guide when the movable plate 5 moves.

Further, the moving plate 2 is provided with a mounting hole 8 for installing the header mounting column 3 and the upper end of the moving plate 2 is divided into a left clamping plate 9 and a right clamping plate 10 and is connected with the mounting hole. 8 communicated with the upper separation opening 11, the left clamping plate 9 is provided with a screw mounting hole 12, the right clamping plate 10 is provided with a threaded hole 13, and the screw mounting hole 12 is provided with a screw connection The fastening screw in the threaded hole 13, the width of the upper separation opening 11 is 2-3mm, which communicates with the upper surface of the moving plate.
