The top of the slide seat 7 is fixedly connected to the movable extension table 8. The movable extension table 8 is wider than the workbench 5 and can place large extrusion molds. At the same time, the movable extension table 8 is made of high-strength steel. The bottom end of the slide seat 7 is fixedly connected to a driving mechanism, and the driving mechanism is used to drive the slide seat 7 to move horizontally in the slide groove a6 of the workbench 5. The slide seat 7 and the slide groove a6 slide like a dovetail groove. A slide groove b9 is provided at the bottom end of the slide groove a6, and a mounting groove 10 is provided directly below the slide groove b9. The slide groove a6, the slide groove b9 and the mounting groove 10 are interconnected, so that the driving mechanism drives the slide seat 7 to move. A switch 11 is provided on the surface of the column 2, and the switch 11 is used to control the motor 12, the driving mechanism is composed of a motor 12, a screw 13, a threaded block 14, a bearing 15 and a connecting rod 16, etc. A motor 12 is fixedly installed inside the mounting groove 10, the motor 12 is electrically connected to the switch 11, and the motor 12 is electrically connected to the rocker arm 3 drilling machine, and can also be connected to an external power supply. The output end of the motor 12 is transmission-connected with a screw 13, and the other end of the screw 13 is installed with a bearing 15, which is fixed in the mounting groove 10. The screw 13 rotates on the bearing 15, and the surface of the screw 13 is movably connected with a threaded block 14, and the internal thread of the threaded block 14 matches the external thread of the screw 13, so the threaded block 14 can move on the surface of the screw 13, and the top of the threaded block 14 is fixedly connected with a connecting rod 16, and the connecting rod 16 passes through the slide groove b9 from the mounting groove 10 and is fixedly connected to the slide seat 7 inside the slide groove a6, so when the connecting rod 16 moves, it can drive the slide seat 7 to move.

[0025] Furthermore, support rods 17 are provided at both ends of the workbench 5. There are four support rods 17, which are respectively arranged around the workbench 5 and are arranged in a rectangular shape. A rotating shaft is fixed on the support rod 17, and the rotating shaft is rotatably connected to the pulley a18. Therefore, the pulley a18 rotates at the top of the support rod 17, thereby improving the smoothness and stability of the movable extension platform 8 moving on the surface of the workbench 5.

[0026] Furthermore, the number of pulleys a18 and the number of support rods 17 match each other, both being four, and the pulleys a18 are also arranged in a rectangular shape consistent with the support rods 17, and the rectangular arrangement is more stable.

[0027] Furthermore, two pulley grooves 19 are provided at the top inner part of the workbench 5, and the two slide groove wheels are located on both sides of the slide groove a6 and are arranged in parallel. A rotating shaft is installed in the pulley groove 19, and the rotating shaft is rotatably connected with the pulley b20, so that the pulley b20 rotates in the pulley groove 19. A guide groove 21 matching the pulley b20 is provided at the bottom inner part of the movable extension platform 8, and the pulley b20 moves along the slide rail, thereby improving the smoothness and stability of the movable extension platform 8 moving on the surface of the workbench 5.

[0028] Furthermore, the pulley a18 and the pulley b20 are arranged in a straight line, which improves the rotation stability between the pulley a18 and the pulley b20.

[0029] Furthermore, the cross-shaped arrangement of the slide groove a6 and the slide seat 7 can not only be moved, but also limited by their structure to prevent the slide seat 7 from falling off.

[0030] The working principle of this embodiment is as follows: when in use, first place the object on the mobile extension table 8 for processing. When the size of the object exceeds the working range of the column 2 and the rocker arm 3, the switch 11 can be pressed to control the motor 12 to rotate. The motor 12 drives the screw 13 to rotate on the bearing 15, so that the screw 13 rotates in the threaded block 14. The threaded block 14 converts the rotational motion into the left and right linear motion of the threaded block 14. Just like the principle of a ball screw, the threaded block 14 moves while driving the connecting rod 16 to move in the slide groove b9. At the same time, the connecting rod 16 drives the slide seat 7 to move in the slide groove a6. When the slide seat 7 moves, it can drive the mobile extension table 8 to move on the workbench 5. When the mobile extension table 8 moves, the pulley b20 moves along the guide groove 21, improving The smoothness and stability of the movement of the mobile extension platform 8 are improved. At the same time, the mobile extension platform 8 drives the pulley a18 to move, and the support rod 17 can effectively support it and assist the movement, further improving the smoothness and stability of the movement of the mobile extension platform 8, thereby driving the object on the top of the mobile extension platform 8 to move. When it reaches the appropriate position, press the switch 11 again. When moving the mobile extension platform 8 in the reverse direction, press the switch 11 again, and the motor 12 can be reversed to drive the mobile extension platform 8 to move in the reverse direction, thereby improving the adaptability of the radial drilling machine. By adjusting the position of the large extrusion mold on the mobile extension platform 8, the limited moving distance of the rocker arm 3 and the rotation range of the column 2 are compensated, so that large objects can be drilled, thereby improving the practicality and adaptability of the radial drilling machine.
