Description

Technical Field

[0001] This utility model relates to the field of gantry machining centers, and more specifically, to an automatic exchange mechanism for a gantry machining center with dual worktables. Background Technology

[0002] Most existing machining equipment or automated machining equipment uses a single worktable to fix the workpiece. When this single worktable is working, the machining equipment needs to stop working and wait for the worktable to be changed. Since changing the workpiece on the worktable takes up the machining equipment's working time, it will inevitably reduce the production efficiency of the machining equipment.

[0003] Existing dual-worktable exchange equipment for hardware processing is problematic because most hardware processing equipment is equipped with dual worktables to enable different processing steps for hardware tools. The difficulty in adjusting the dual worktables makes rapid exchange between them difficult, thus affecting processing efficiency. Furthermore, after the dual worktables are exchanged, their inability to move horizontally necessitates readjusting the hardware positions when processing different parts of the worktables. This readjustment is time-consuming and cumbersome, further impacting hardware processing efficiency.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

Detailed Implementation

[0018] The utility model will now be further described with reference to the accompanying drawings and specific embodiments: Please see Figure 1-9According to an embodiment of the present invention, an automatic exchange mechanism for a gantry machining center with dual worktables includes a platform support 1. A support platform 2 is provided on the surface of the platform support 1. A base plate 3, a vertical plate 4, and a drive motor 5 are provided on the surface of the support platform 2. A support screw 6 is provided at the drive end of the drive motor 5. A movable slider 7 is screwed onto the surface of the support screw 6. An exchange table base 8 is provided on the surface of the movable slider 7. By starting the drive motor 5, the support screw 6 is rotated, thereby facilitating the displacement of the movable slider 7 along the support screw 6. This facilitates the adjustment of the positions of the two sets of worktables 12 above the exchange table base 8, thereby enabling the machining center to process the workpieces on the other set of worktables 12.

[0019] The base 8 of the exchange station is provided with a mounting plate 9, a guide rail 10, a guide rail slider 11, and a worktable 12. There are two sets of mounting plates 9, which are located at opposite ends of the surface of the base 8 of the exchange station. The base 8 of the exchange station is provided with a hydraulic cylinder 13, and a push plate 14 is fixedly connected to the telescopic end of the hydraulic cylinder 13. The guide rail 10 facilitates the displacement of the guide rail slider 11. In addition, the cooperation between the guide rail 10 and the guide rail slider 11 facilitates the support of the worktable 12, reducing the pressure of the worktable 12 on the telescopic end of the hydraulic cylinder 13. The hydraulic cylinder 13 facilitates the pushing of the push plate 14.

[0020] Please see Figure 1 , Figure 2 and Figure 8 As shown, the upright plate 4 is fixedly connected to the surface of the support platform 2. A positioning bearing 15 is provided on the side of the upright plate 4. One end of the support screw 6 is fixedly connected to the inner ring surface of the positioning bearing 15, and the other end of the support screw 6 is fixedly connected to the drive end of the drive motor 5. When the drive motor 5 is started, the support screw 6 rotates in conjunction with the positioning bearing 15, thereby causing the movable slider 7 screwed on the support screw 6 to move. Through the support of the positioning bearing 15 on one end of the support screw 6, and in conjunction with the support of the guide plate 17 and the movable block 21, the downward pressure of the support screw 6 on the drive end of the drive motor 5 is reduced, making it easier for the drive motor 5 to drive the support screw 6 to rotate.

[0021] Please see Figure 2 and Figure 3As shown, the base plate 3 is fixedly connected to the surface of the support platform 2. A placement plate 16 is provided on the surface of the base plate 3, and a guide plate 17 is provided on the surface of the placement plate 16. A moving groove 18 is opened on the surface of the guide plate 17, and a rotating rod 19 is provided on the side of the moving groove 18. An auxiliary wheel 20 is sleeved on the surface of the rotating rod 19. Multiple sets of rotating rods 19 are arranged linearly at equal intervals about the side of the moving groove 18. A moving block 21 is sleeved on the surface of the guide plate 17 and is slidably connected to the guide plate 17. The exchange table base 8 is fixedly connected to the surface of the moving block 21. When the moving block 21 slides on the guide plate 17, the rotation of multiple sets of auxiliary wheels 20 helps to reduce the friction between the moving block 21 and the guide plate 17, thereby facilitating the drive motor 5 to drive the moving slider 7 to move by driving the support screw 6. The guide plate 17 has an overall "T" shaped plate structure to prevent the moving block 21 from detaching from the guide plate 17.

[0022] Please see Figures 4-7 and Figure 9 As shown, the push plate 14 is fixedly connected to the bottom of the workbench 12. The telescopic end of the hydraulic cylinder 13 passes through the mounting plate 9. An auxiliary plate 22 is provided on the surface of the mounting plate 9. The side of the auxiliary plate 22 is provided with a Velcro surface 27. A limit plate 23 is provided on the end face of the workbench 12. A wave-shaped cover 24 and a traction plate 25 are provided on the side of the limit plate 23. One end of the traction plate 25 passes through the auxiliary plate 22. One end of the wave-shaped cover 24 is fixedly connected to the side of the limit plate 23. A limit block 28 is provided on the other end of the wave-shaped cover 24. The surface of the limit block 28 is provided with a Velcro surface 26. When the push plate 14 is pushed by the hydraulic cylinder 13, it is convenient to drive the workbench 12 to be further lifted. The adjustment mechanism improves the convenience of machining in the machining center. In addition, the cooperation between the guide rail 10 and the guide rail slider 11 can reduce the downward pressure of the worktable 12 on the extension end of the hydraulic cylinder 13. When the worktable 12 is displaced, it can drive the wave cover 24 to unfold or retract and fold. The traction plate 25 can limit the upper part of the wave cover 24 to prevent the wave cover 24 from tilting. The unfolding of the wave cover 24 can prevent the debris generated by the machining center from falling between the two sets of guide rails 10, which is inconvenient to clean. In addition, the adhesion between the Velcro plane 26 and the Velcro rough surface 27 facilitates subsequent disassembly. The traction plate 24 can slide within the auxiliary plate 22.

[0023] Through the above-described solution of this utility model, the drive motor 5 can drive the support screw 6 to rotate, thereby facilitating the displacement of the movable slider 7. This allows for the adjustment of the positions of the two sets of worktables 12 above the exchange table base 8, enabling the two sets of worktables 12 to quickly exchange positions. After processing the workpiece on one set of worktables 12, the positions of the two sets of worktables 12 can be adjusted by the displacement of the exchange table base 8, facilitating the machining center to process the workpieces on both sets of worktables 12. In addition, the hydraulic cylinder 13 can facilitate the adjustment and displacement of the worktables 12 along the direction of the guide rail 10, allowing for further adjustment of the workpieces on the worktables 12 to adapt to the machining center's processing of the workpieces.
