At the same time, the power-assisted arm marking machine is also suitable for other industries that require high-precision and high-efficiency marking operations, such as machinery manufacturing, electronic manufacturing, etc.

[0003] During the body coding operation, the power-assisted arm-type marking machine fixture is hung at the end of the power-assisted arm. Due to on-site construction and installation errors, as well as the force and deformation of the power-assisted arm itself, the posture of the fixture relative to the body deviates, so the fixture needs to be fine-tuned. At present, the posture adjustment device of the power-assisted arm-type marking machine fixture is generally composed of two parts: a horizontal axis rotation adjustment and a vertical axis rotation adjustment, and the two parts are connected by bolts. Among them, the horizontal axis rotation adjustment part includes two pins as the rotating shaft, and the rotation fine-tuning around the two pins is achieved by turning the screws; the rotating shaft of the vertical axis rotation adjustment is installed in the rotating drum through bearings and round nuts, and the fine-tuning around the rotating shaft is achieved by turning the screws.

[0007] A further improvement of the utility model is that both the adjusting rod A and the adjusting rod B are bolts, the screw rod of the adjusting rod A is used to abut against the adjusting block, and the head of the adjusting rod B is used to abut against the mounting panel.

[0008] A further improvement of the utility model is that a buffer pad is provided on the contact surface between the screw rod of the adjusting rod A and the adjusting block, and a buffer pad is provided on the contact surface between the head of the adjusting rod B and the mounting panel.

[0009] A further improvement of the utility model is that a connecting line between the vertical through holes on the two support plates forms a rectangular structure surrounding the bearing seat.

[0010] A further improvement of the utility model is that the spherical bearing is installed inside the bearing seat through a bearing cover, and spacer rings are installed on the connecting shafts on both sides of the spherical bearing.
