[0010] In summary, this application has the following beneficial technical effects:

[0011] 1. Through the mutual cooperation among the servo motor, worm, worm and rotating shaft, and the close engagement between the worm and the worm wheel, the rotation of the worm drives the worm wheel to rotate, so that the workbench is driven to rotate slowly on the top of the base, so that the workpiece on the top of the workbench can be adjusted to the position where processing is required; compared with the existing technology, the multiple clamping of the workpiece is reduced, the labor intensity is reduced, and the working efficiency of the radial drilling machine is improved.

Due to the low transmission efficiency between the worm wheel 9 and the worm 10, it takes dozens of turns for the worm 10 to drive the worm wheel 9 to rotate one circle, which helps the staff to accurately adjust the angle of the workpiece on the top of the workbench 3, so as to facilitate more precise processing of the workpiece, thereby achieving the effect of facilitating the adjustment of the angle of the workpiece to be processed.

A threaded rod 12 is rotatably connected to one side of the inner part of the slide groove 7, and the two threaded rods 12 extend into the interior of the rotation groove 15. By respectively installing the two threaded rods 12 in the two slide grooves 7, the threaded rod 12 can rotate inside the slide groove 7, wherein the outer wall spiral of the threaded rod 12 is set to twenty degrees.

[0025] Furthermore, the second bevel gear 14 is fixedly connected to the opposite side of the two threaded rods 12, and the first bevel gear 13 is rotatably connected to the side corresponding to the second bevel gear 14 inside the rotating groove 15. The first bevel gear 13 and the two second bevel gears 14 are tightly engaged. The opposite ends of the two threaded rods 12 extend into the rotating groove 15, and the second bevel gear 14 is installed on the opposite side of the threaded rod 12. The first bevel gear 13 is tightly engaged with the two second bevel gears 14, so that the rotation of the first bevel gear 13 drives the two second bevel gears 14 to rotate simultaneously, and then drives the threaded rods 12 on both sides to rotate simultaneously inside the slide groove 7.

[0026] Furthermore, one side of the outer wall of the threaded rod 12 is threadedly connected with a slider 16, wherein the threaded rod 12 and the slider 16 are threadedly connected, and the thread of the threaded rod 12 is smaller than the equivalent friction angle of the spiral pair composed of the threaded rod 12 and the slider 16, forming a self-locking, to prevent movement due to external reasons, the upper surface of the workbench 3 is slidably connected to the splint 6 through two sliders 16, the interior of the workbench 3 is rotatably connected to the connecting rod 17 through the first bevel gear 13, and one side of the connecting rod 17 is fixedly connected to the knob 5, and the knob 5 is connected to the first bevel gear 13 through the connecting rod 17, so that The knob 5 is rotated to drive the first bevel gear 13 to rotate inside the rotating groove 15, and then drive the second bevel gears 14 on both sides to rotate at the same time, and the second bevel gear 14 is connected to the threaded rod 12 through the second bevel gear 14, thereby driving the threaded rods 12 on both sides to rotate inside the slide groove 7, so that the sliders 16 on both sides are driven to move toward each other, and the sliders 16 are connected to the clamping plates 6, so that the clamping plates 6 on both sides are driven to move toward each other, clamping and fixing the workpiece placed on the top of the workbench 3, so that the workpiece will not loosen during processing, thereby achieving the effect of improving the accuracy of the work.

[0028] The implementation principle of the adjustment structure of a radial drilling machine in the embodiment of the present application is as follows: when the device is in use, a workpiece is placed on the top of the workbench 3, and the knob 5 is turned to drive the connecting rod 17 to rotate, so that the first bevel gear 13 inside the rotating groove 15 is driven to rotate, and the first bevel gear 13 is tightly meshed with the two second bevel gears 14, and the first bevel gear 13 is connected to the threaded rod 12, and then the threaded rods 12 on both sides are driven to rotate simultaneously inside the sliding groove 7, and are connected to the slider 16 through the threaded rod 12, and are connected to the clamping plate 6 through the slider 16. This drives the clamping plates 6 on both sides to move toward each other to clamp and fix the workpiece. Subsequently, the servo motor 4 is started to drive the worm 10 to rotate inside the cavity 8. The worm 10 and the worm wheel 9 are tightly engaged, and the worm wheel 9 is connected to the workbench 3 through the rotating shaft 11. The worm 10 then rotates to drive the worm wheel 9 to rotate, so that the workbench 3 is driven to rotate slowly on the top of the base 1, so that the workpiece on the top of the workbench 3 can be adjusted to the position that needs to be processed. The self-locking property between the worm wheel 9 and the worm 10 prevents the workpiece itself and the workbench 3 from rotating during processing.
