[0002] A marking machine is a machine used to mark parts, measuring tools, etc. for easy identification. Commonly used machines include pneumatic marking machines, metal electroprinting marking machines, sign parameter engraving machines, and electric handheld marking devices. The content of the Chinese and English characters and graphics to be printed is input into the computer. The computer marking software converts the content into digital control signals and transmits them to the controller, which drives the printing to print characters and graphics consisting of a continuous dot matrix on the workpiece; the needle moves along the set trajectory in the X-Y two-dimensional plane, and the printing needle is acted upon by compressed air to print a concave mark consisting of a dense dot matrix on the surface of the workpiece.

[0003] The existing machine head has a complex structure. When it needs to be repaired or replaced with a machine head with different functions, the operation is very cumbersome. The traditional connection method between the machine head and the marking machine body mostly uses multiple bolts, which not only requires the use of special tools in the disassembly process, but also takes a long time.

[0016] The utility model provides an easily replaceable pneumatic marking machine head, which has the following beneficial effects:

[0017] (1) According to the present invention, when the operator needs to replace the needle, he first rotates the position of the U-shaped limit block. After the U-shaped limit block rotates inside the connecting plate, the position of the rotating handle will not be limited. Then the operator can directly rotate the position of the rotating handle. The rotating handle drives the positioning ring to rotate on the side wall of the mounting block. Since the inner wall of the positioning ring is threadedly connected to the side wall of the mounting block, when the positioning ring is separated from the side wall of the mounting block, the operator can disassemble the position of the needle and install the position of the needle by reverse operation, saving the operator's workload and solving the problem that the existing machine head structure is complex. When it is necessary to repair or replace a machine head with different functions, the operation is very cumbersome. The traditional connection method between the machine head and the marking machine body is mostly fixed with multiple bolts, which not only requires the use of special tools for the disassembly process, but also takes a long time.

[0018] (2) In the present invention, the operator places the object to be marked on the top of the fixed plate, and then directly rotates the position of the turntable, which drives the position of the threaded rod to rotate. Since the side wall of the threaded rod is threadedly connected to the inner wall of the rectangular plate, when the threaded rod rotates, the position of the clamping plate can be moved. Under the joint action of the clamping plate and the side plate, the position of the object is effectively stabilized, which is convenient for better processing and marking in the later stage.
