In the process of machining round pipe parts, laser is often needed to be used for rotationally marking the round pipe parts, and in the process of rotationally marking the laser, a laser machining area is ensured to be always in an area right above the round pipe and located at the focus of a galvanometer or in the focal depth range, and meanwhile, the whole circle of machining is required to be complete in pattern and free of seams.

The traditional laser rotary marking method can directly neglect the change of the arc focus when carrying out rotary marking on small pixels, so that the situation that the edge part is not in the focus can be caused when carrying out fixed-point marking after rotary positioning, and the phenomenon of uneven sample effect can be caused. When large primitives or round pipe full circle primitives are processed, the whole primitives can be split into a plurality of strips, and each strip position is rotationally positioned to carry out rotary splicing marking, so that the condition of obvious seams often occurs, and the whole circle of patterns become broken, and the good marking effect is difficult to achieve.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Fig. 1 schematically shows a structure of a rotary gang marking apparatus according to an embodiment of the present invention, fig. 2 shows a flow of a processing method of the rotary gang marking apparatus of fig. 1, and fig. 3 shows an interface of the processing method of the rotary gang marking apparatus of fig. 1 when software setting is performed. As shown in fig. 1-3, the apparatus needs to be used with a computer and corresponding control system. The equipment comprises a workbench 1, and other mechanisms are directly or indirectly arranged on the workbench 1.

The mechanism directly mounted on the table 1 has a chuck 2, a column 3 and a bracket 6. The chuck 2 is a three-jaw chuck and its jaws are located on its side, while the jaws of the chuck 2 are used to grip a round tube workpiece 5 to be marked. Wherein, dress pipe work piece 5 is the level when the installation and places, and its one end is installed on the clamping jaw of chuck 2, and the other end can set up on bracket 6 to guarantee its stability of installing and placing.

The galvanometer 4 is mounted on the column 3, and the galvanometer 4 can slide in a certain range in the vertical direction along the column 3. Wherein, stand 3 is hand stand, and its top is provided with crank 7, then when manual operation crank 7, the mirror 4 that shakes can slide in order to adjust its height in time, and then reaches the effect of focusing.

When the rotary linkage marking device is used, the operation method mainly comprises several steps as follows.

In the first step, a round tube workpiece 5 to be marked is clamped on a chuck 2, and the other end of the round tube workpiece is placed on a bracket 6. This operation is typically performed manually.

And secondly, loading preset relevant software into a rotary marking drawing file (such as a vector diagram), and setting relevant processes and processing parameters of rotary processing. The processing parameters mainly include a filling angle perpendicular to the rotation direction, a corresponding processing speed, and the like.

And thirdly, operating a hand crank 7 of the upright post 3 to vertically move the galvanometer 4 on the upright post so as to adjust the height of the galvanometer to the focus position, thereby realizing accurate focusing. After focusing is completed, the file can be transmitted to complete the pre-preparation of marking work.

Under the condition of having the preview function, after the height of the galvanometer 4 is adjusted and focusing is completed, the position of the machining graph on the workpiece can be previewed first, and the height of the galvanometer 4 is finely adjusted to a certain extent according to the position, and then the file is transmitted.
