the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 and 2, the surrounding sword fence for the laser cutting system comprises a main body frame 1, a motor driving assembly 2, a guide wheel guiding assembly 3, an expansion adjusting assembly 4 and a sword fence assembly 5. The utility model discloses in, the sword bars subassembly is connected with the periphery of hold-in range, and relative displacement does not take place for the hold-in range for the sword bars subassembly. It can be understood that the synchronous belt may be elastically deformed, even if the sword fence assembly does not slide or move due to other properties relative to the synchronous belt under the condition that the synchronous belt is elastically deformed or permanently deformed, the sword fence assembly is always fixed on a specific position of the synchronous belt. In the same way, when the sword fence assembly rotates and the systematic synchronous belt changes, other factors can be adjusted in time, so that the original X-direction accuracy of the synchronous belt is still maintained.

Fig. 3 is a transverse cross-section of the frame of fig. 1 showing the components: a left support bracket 22, a right support bracket 23, a middle bracket 24 and lifting lugs 21 and 22. The frame in fig. 3 can provide a frame with strong rigidity, thereby ensuring the stability of the whole device. The lifting lug can be convenient for the lifting of equipment.

Fig. 4 is a side schematic view of a laser cutting system. It can be seen that the surrounding fence of the laser cutting system can be cycled, providing support for continued laser cutting.

Fig. 5 is an enlarged side view of the laser cutting system, particularly illustrating the motor drive assembly 2 therein. The motor driving component 2 comprises a servo motor, the servo motor drives a transmission system, and the transmission system further drives a synchronous belt to move so as to drive the surrounding sword fence to move.

Figures 6, 8, and 9 are schematic views of a guide wheel guide assembly. The guide wheel assembly is provided with two groups of fixed guide wheels 16, two groups of follow-up guide wheels 17 and fixed supporting guide wheels 18 in the Y direction. The fixed supporting guide wheel 18 is arranged on the main body frame 1, and the fixed guide wheel 16 and the eccentric guide wheel 17 are arranged on the synchronous belt. When the synchronous belt moves, the fixed guide wheel 16 and the follow-up guide wheel 17 can be matched with the fixed supporting guide wheel 18, so that the guide wheel can be guided in the Y direction.

The axial directions of the two groups of fixed guide wheels 16 and the two groups of follow-up guide wheels 17 in the figures 8 and 9 are perpendicular to the ground direction, and the two groups of fixed guide wheels and the two groups of follow-up guide wheels can be accommodated in the guide grooves. The fixed guide wheel 16 and the follow-up guide wheel 17 slide in the guide groove, so that the friction force is reduced, the deviation is corrected in time, and the correctness of the direction of the sword fence is ensured. The fixed supporting guide wheel 18 is also accommodated in the guide groove, the axial direction of the fixed supporting guide wheel is parallel to the horizontal direction, and the fixed supporting guide wheel 18 is installed in the guide groove and fixed in the main body frame, so that the synchronous belt and the main body frame can always keep a proper Z-direction relative position.

As can be seen from fig. 8 and 9, the synchronous belt accommodates the fixed guide wheel 16, the follow-up guide wheel 17 and the fixed supporting guide wheel 18 therein through the guide grooves, so that the sword fence operates stably, has stable position and distance, and does not generate processing defects caused by jumping and the like in the laser cutting process.

In fig. 6, below the bracket, when the timing belt carrying the sword fence runs to the support surface downward, the support guide wheel 15 on the guide wheel guide assembly is supported by the support block 10, thereby preventing the Z of the timing belt from drooping downward.

Fig. 7 is a schematic structural view of the expansion adjustment assembly. Wherein tight adjusting part expands is fixed on dog 31 by adjusting bolt 30, and adjusting bolt connects on the dog, adjusting bolt and spring lug connection, and tight support and spring lug connection expand, and adjusting bolt 30 front and back position comes extrusion spring 32 to produce the pretightning force to tight support 33 that expands, owing to be elastic pretightning force, consequently the hold-in range can realize the tensioning in the X direction to satisfy the ascending accuracy in X direction, guaranteed the accuracy nature of processing.

Example (b):

after the power is on, the motor driving component 2 drives the synchronous belt to move. The rapier fence carried by the timing belt moves along the guide groove 19 under the guidance of the guide wheel assembly, ensuring the accuracy in the Y direction. When the leading wheel moves to a certain position to the sword fence supporting surface is down, the leading wheel subassembly supports and ensures the ascending accuracy of Z direction, has avoided the tensile force that the dead weight of hold-in range unnecessary formed. When the detection shows that the transmission belt is deformed, the front position and the rear position of the adjusting bolt 30 of the expansion adjusting assembly are adjusted to extrude the spring 32 to generate pretightening force on the expansion block support 33, so that the synchronous belt can be tensioned in the X direction, and the X-direction accuracy is met.

The motor driving component 2 drives the sword fence to rotate around, and is matched with the appearance of the continuously-cut plate of the laser cutting head to finish continuous laser cutting.
