Technical Field

[0001] The utility model relates to the technical field of pneumatic marking, in particular to a pneumatic marking device. Background Art

[0002] The working principle of the pneumatic marking machine is to use the high-frequency vibration of the printing steel needle under the action of high-pressure gas to impact the workpiece, and print dense dot matrix on the surface of the workpiece to form permanent characters or graphics. After searching: a pneumatic marking device with the authorization publication number CN210970488U includes a mounting mechanism and a marking mechanism; the marking mechanism includes a mounting plate, a turntable, a moving plate, a pneumatic marking head, a first motor, a first driving member, and a second driving member. The mounting plate is fixedly mounted below the cantilever, the turntable is rotatably mounted below the mounting plate, the moving plate is movably mounted below the turntable, and the pneumatic marking head is movably mounted below the moving plate; the first motor is mounted on the mounting plate, and the first motor is connected to the turntable for driving the turntable to rotate; the first driving member is connected to the moving plate for driving the moving plate to move radially along the turntable; the second driving member is connected to the pneumatic marking head for driving the pneumatic marking head to move radially along the moving plate.

[0003] However, the pneumatic marking device mentioned above still has some shortcomings. First, the workpiece to be pneumatically marked is not effectively clamped and fixed, which makes the workpiece easy to deviate and shake, affecting the marking accuracy. It is also inconvenient to effectively and accurately adjust the marking head and the workpiece, and thus it is impossible to calibrate the marking head and the position to be marked, further reducing the marking quality. Therefore, we propose a pneumatic marking device to solve the above problems. Utility Model Content

Finally, the cylinder is started to drive the marking head downward to perform pneumatic marking on the workpiece.

[0018] The utility model is further configured as follows: a guide rail groove is provided on the top of the gantry, and the mounting seat is slidably sleeved in the guide rail groove.

[0019] By adopting the above technical solution, the mounting seat can be guided to make its movement more stable and smooth.
