Embodiment 2

[0042] Reference Figure 4 and Figure 5 As shown, a beam driving device for a gantry machining center includes a top shell 101, in which a horizontal guide rail 4 is fixedly arranged, a driving plate 5 is arranged in the middle of the horizontal guide rail 4, and auxiliary seats 6 slidingly matched with the horizontal guide rail 4 are arranged at both ends of the driving plate 5. The auxiliary seat 6 is rotatably connected to the driving plate 5, and a locking assembly 7 is fixedly installed on the auxiliary seat 6.

[0043] Reference Fig.13 , Fig.14 and Fig.15 As shown, the locking assembly 7 includes a main body shell 71, a threaded rod group 72, a synchronous frame 73, a locking frame 74 and a driving electric cylinder 75. The main body shell 71 is fixedly mounted on the seat plate 61, the threaded rod group 72 is threadedly connected to the main body shell 71, and the head of the threaded rod group 72 is in contact with the side shaft 511, the synchronous frame 73 is sleeved on the end of the threaded rod group 72, the locking frame 74 is mounted on the outer side of the main body shell 71, and the locking frame 74 is longitudinally slidably connected to the main body shell 71, and the driving electric cylinder 75 is fixedly mounted on the main body shell 71, and the output end of the driving electric cylinder 75 is connected to the locking frame 74. The structure of the locking assembly 7 is set to ensure that the threaded rod group 72, the synchronous frame 73, the locking frame 74 and the driving electric cylinder 75 are installed on the main shell 71. During use, the threaded rod group 72 can be rotated to press and hold one end of the side shaft 511, so that the side shaft 511 cannot be rotated normally, and the driving plate 5 can slide horizontally stably. The setting of the synchronous frame 73 and the locking frame 74 can ensure that the driving electric cylinder 75 can move up and down when in use. In this way, when the locking frame 74 is pressed on the positioning cross rail 42, the driving plate 5 can be locked for horizontal movement, ensuring that the driving plate 5 can only be rotated and adjusted by the side shaft 511, thereby realizing two driving modes of the driving plate 5.

[0044] Reference Fig.13 , Fig.14 and Fig.15As shown, the main body shell 71 includes a shell 711, a top plate 712, and a threaded sleeve 713 for installing the threaded rod group 72. The top plate 712 is arranged on the upper end surface of the shell 711, and the top plate 712 and the shell 711 are integrally formed. The threaded sleeve 713, the outer surface of the shell 711 is provided with a vertical rail shell 714 for slidingly installing the locking frame 74, and the vertical rail shell 714 is fixedly connected to the shell 711. By setting the structure of the main body shell 71, it is ensured that the top plate 712 is fixedly installed on the shell 711, and it is easy to fix the driving electric cylinder 75 through the top plate 712, so that the driving electric cylinder 75 can be stably driven during use. At the same time, by fixing the threaded sleeve 713 in the middle of the shell 711, it is convenient for the threaded rod group 72 to pass through the threaded sleeve 713 for connection, so that the threaded rod group 72 can be adjusted in the threaded sleeve 713 by rotation during use. By fixing the vertical rail shell 714 on the outer surface, it is convenient to slide the locking frame 74 through the vertical rail shell 714 during use.

[0045] Reference Fig.13 , Fig.14 and Fig.15 As shown, the synchronous frame 73 includes a ring 731 and a connecting frame 732. The connecting frame 732 is integrally formed and arranged on the outer side of the ring 731. The inner side of the ring 731 is also symmetrically provided with a matching finger 733. The end of the threaded rod group 72 is provided with a matching groove 721 corresponding to the matching finger 733. The structural setting of the synchronous frame 73 ensures that the ring 731 can be sleeved on the end of the threaded rod group 72 when in use, and the setting of the matching finger 733 and the matching groove 721 ensures that the threaded rod group 72 can be rotated and adjusted after the ring 731 is sleeved on the threaded rod group 72. At the same time, by arranging the connecting frame 732 on the ring 731, it is convenient to cooperate with the locking frame 74 through the connecting frame 732.

[0046] Reference Fig.13 , Fig.14 and Fig.15As shown, the locking frame 74 includes a sliding seat 741, a linkage outer rod 742 and a holding seat 743. The sliding seat 741 is slidably installed in the vertical rail shell 714, the linkage outer rod 742 is vertically fixed on the outer side of the sliding seat 741, and the linkage outer rod 742 passes through the middle of the connecting frame 732. The lower end surface of the holding seat 743 is also fixedly installed with a brake plate 744. The structural setting of the locking frame 74 ensures that the linkage outer rod 742 and the holding seat 743 are fixedly installed on the sliding seat 741, and ensures that the linkage outer rod 742 and the holding seat 743 can achieve synchronous movement under the drive of the sliding seat 741 during use. In this way, when the sliding seat 741 moves up and down, the synchronization frame 73 can be driven to rotate through the linkage outer rod 742, and then the threaded rod group 72 can be driven to rotate and adjust. At the same time, the holding seat 743 can drive the brake plate 744 to move up and down. When moving downward, the brake plate 744 can be pressed and held on the positioning cross rail 42, and the friction force can be used to achieve rapid locking movement.

[0047] Working principle: During the actual use of the machining center, the driving electric cylinder can be started to move the locking frame upward, and the sliding seat drives the holding seat and the brake plate to move up, so that the brake plate and the positioning cross rail are separated from each other, and the outer rod is linked to drive the threaded rod group to rotate forward, so that the head of the threaded rod group is stably pressed on the side shaft of the driving plate, and the side shaft and the threaded rod group are fixed to each other through friction, so that the driving plate cannot rotate through the side shaft. When the screw group is started to drive the nut seat to move, the nut seat drives the driving plate to slide along the horizontal guide rail through the connecting frame and the linkage frame, and then drives the movable slider to move on the slide rail through the walking seat, and then drives the driving plate to slide through the screw group to drive the operation.

[0048] When precise adjustment is required, the driving electric cylinder is started to move the locking frame downward, and the holding seat and the brake plate are driven downward by the sliding seat to hold the brake plate on the positioning cross rail, so that the driving plate and the horizontal guide rail can be locked with each other and cannot be slidably adjusted. At the same time, the linkage outer rod drives the threaded rod group to rotate in the opposite direction, so that the head of the threaded rod group is stored in the threaded sleeve, thereby releasing the lock on the side shaft of the driving plate, making it convenient for the driving plate to rotate and adjust. In this way, when the screw rod group continues to be started to drive the nut seat to move, the nut seat drives the lower end of the driving plate to move through the connecting frame and the linkage frame, and the driving plate can rotate around the side shaft as the center. The side shaft is used to divide the upper and lower parts of the driving plate into different proportions, and the distance moved by the upper walking seat can be calculated according to the lower end moving distance. For example, the side shaft is set at the quarter-division point of the driving plate height, so that the height of the lower end is three times that of the upper end of the side shaft. When the lower end of the driving plate moves 3mm, the upper end only moves 1mm. In this way, by dividing the moving distance into equal parts, it is easier to control the moving accuracy.
