[0018] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0019] like Figure 1 , Figure 2 As shown, the utility model is a base of a table automatic exchange device, including a base 1, a guide rail 2, a slider 3, a saddle 4, a hydraulic cylinder 5, a connecting block 6, a travel bumper 7, a wiring trough 8, a cable drag chain 9 and a proximity switch. The base 1 is the installation platform of the entire device. The base 1 is U-shaped. Guide rails 2 are provided on the left and right sides of the base 1. Sliders 3 are provided on the guide rails 2. A saddle 4 is provided on the base 1. The saddle 4 cooperates with the guide rails 2 and sliders 3 on the base 1 to achieve forward and backward movement. A hydraulic cylinder 5 is provided in the base 1. A connecting block 6 is provided on the hydraulic cylinder 5. The connecting block 6 is connected to the saddle 4, and power is transmitted to the saddle 4 through the connecting block 6 to achieve forward and backward movement. One end of the connecting block 6 is fixed on the hydraulic cylinder 5, and the other end is fixed on the bottom of the saddle 4. Two travel bumpers 7 are provided on one side of the base 1 to control the travel of the saddle 4. Screws are provided on the top to fine-tune the travel according to actual conditions. A wiring groove 8 is provided on the other side, and the cables in the saddle 4 enter the cable drag chain 9 through the wiring groove 8. The other end of the cable drag chain 9 is fixed on the saddle 4 and moves with it. A proximity switch is provided on one side of the base 1 with the wiring groove 8.

[0020] The proximity switches include a first proximity switch 10 , a second proximity switch 11 and a third proximity switch 12 , and the three proximity switches can control the movement of the saddle 4 .

[0021] Four lifting holes 13 are provided on both sides of the base 1 for lifting during transportation and installation of the base 1. Anchor bolts 14 are provided under the base 1 for fixing on the foundation.

[0022] Function of guide rail 2 and slider 3: to realize forward and backward movement of saddle 4. Function of hydraulic cylinder 5: the power source of the whole device. Function of connecting block 6: to transmit the force of hydraulic cylinder 5 to saddle 4 to realize the movement of saddle 4. Function of travel bumper 7: to control the travel of saddle. Function of cable drag chain 9: to pull and protect cables, oil pipes, air pipes, etc. used in moving parts. Function of first proximity switch 10: to stop saddle from moving backward. Function of second proximity switch 11: to slow down saddle. Function of third proximity switch 12: to stop saddle from moving forward. Function of hoisting hole 13: for hoisting during installation and transportation of base 1.

[0023] First, the base 1 is fixed to the foundation through the anchor bolts 14. The function of the base 1 is to support the saddle 4 to move linearly. When a complete table exchange is performed, the hydraulic cylinder 5 on the base 1 is first extended, and the force is transmitted to the saddle 4 through the connecting block 6. The saddle 4 moves linearly through the guide rail 2 and the slider 3. When the saddle 4 moves toward the workbench, when the position of the saddle 4 reaches the specified deceleration position, the second proximity switch 11 will detect the sensor on the saddle 4, so that the saddle 4 starts to decelerate. When the third proximity switch 12 detects the sensor on the saddle 4, the saddle 4 stops moving forward. Next, the table exchange can be performed. At this time, the block on the saddle 4 should contact the travel block 7. When the table exchange is completed, the hydraulic cylinder 5 shrinks, and the saddle 4 starts to move in the opposite direction. When the second proximity switch 11 detects the sensor of the saddle 4, the saddle 4 starts to decelerate. When the first proximity switch 10 detects the sensor, the saddle 4 stops moving backward. At this time, the block on the saddle 4 should contact the travel block 7. In this way, a complete table exchange is completed.

[0024] This base is suitable for large boring and milling machines with large travel. When the table needs to be exchanged, no manual intervention is required, and the table can be automatically exchanged. This base has a simple structure and is easy to install, which greatly enhances the competitiveness of the machine tool in the market.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
