[0002] A deep hole drilling machine is a machine tool specially used for processing deep holes. Its design enables the drill bit to drill holes with an aspect ratio greater than 10. These holes are usually deep and relatively small in diameter. Deep hole drilling machines are widely used in mold manufacturing, automotive parts, gun barrel manufacturing and other industries. When processing, deep hole drilling machines need to ensure that the drill bit moves accurately along the predetermined axis. The guide device can provide stable guidance to ensure the processing accuracy of the hole.

However, when using this method, the position of the drill bit cannot be adjusted. The fixed position of the drill bit limits the processing method of the workpiece. It has poor adaptability to workpieces of different shapes and sizes and is difficult to meet diverse processing needs. The inability to accurately adjust the position of the drill bit will cause drilling position deviation, affecting the processing accuracy. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The cylinder 2 is started to push the push block 3 to move smoothly and powerfully. The push block 3 not only moves itself, but also drives the push plate 4 and the positioning plate 5 to move together. The positioning plate 5 guides the positioning seat 8 to move according to the predetermined trajectory. As the positioning seat 8 moves, the right positioning plate 5 and the push plate 4 are also linked. The right push plate 4 is specially designed with sliders 26. These sliders 26 can slide smoothly along the outside of the slide rod 27 to ensure stability and accuracy during the movement. When the two positioning plates 5 move, the pulleys 7 at the bottom thereof slide smoothly on the upper part of the guide rail 6, which greatly reduces friction and improves adjustment. In order to improve the efficiency, under the joint action of the pulley 7 and the slider 26, the positioning seat 8 can drive the drill bit 9 to move back and forth on the upper part of the operating table 1, so that the drill bit 9 can be accurately positioned at each part of the workpiece that needs to be processed. When the drill bit 9 needs to move left and right, the motor 11 is driven, and the output end of the motor 11 drives the gear 12 to rotate. The gear 12 is tightly engaged with the rack plate 13, so that the rack plate 13 can move left and right with the rotation of the gear 12. The rack plate 13 is connected to the drill bit 9. Therefore, the movement of the rack plate 13 directly drives the drill bit 9 to move left and right outside the positioning seat 8.
[0026] Reference Figure 2 , Figure 4 and Figure 5The bottom of the operating table 1 is fixedly connected to a fixed frame 14, the front of the fixed frame 14 is fixedly connected to a hydraulic cylinder 15, the output end of the hydraulic cylinder 15 is fixedly connected to a movable block 16, the upper part of the movable block 16 is fixedly connected to a connecting rod 20, one side of the connecting rod 20 is fixedly connected to a mounting plate 21, the internal thread of the mounting plate 21 is connected to a screw 23, the upper part of the screw 23 is fixedly connected to a turning handle 22, the bottom of the turning handle 22 is threadedly connected to a pressing plate 24, both sides of the inside of the mounting plate 21 are slidably connected to limiting columns 25, the bottoms of multiple limiting columns 25 are fixedly connected to pressing plates 24, both sides of the bottom of the fixed frame 14 are fixedly connected to vertical plates 18, the opposite sides of multiple vertical plates 18 are fixedly connected to limiting rods 19, both sides of the movable block 16 are fixedly connected to limiting plates 17, and multiple limiting plates 17 are slidably connected to the outside of the limiting rods 19.
[0027] Carefully place the workpiece to be processed on the upper part of the operating table 1 to ensure that the workpiece is stable and without shaking. Then, start the two hydraulic cylinders 15. Under the push of the output end of the hydraulic cylinder 15, the movable block 16 begins to move smoothly. The movable block 16 drives the limit plate 17 to slide outside the limit rod 19, which not only ensures the accuracy of the activity, but also greatly enhances the structural stability of the device. Under the precise guidance of the limit plate 17, the movable block 16 continues to drive the connecting rod 20 to move, and the connecting rod 20 further drives the mounting plate 21 to move. When the mounting plate 21 drives the pressure plate 24 to move slowly When it reaches the upper part of the workpiece, it is necessary to further adjust the position and strength of the pressing plate 24. At this time, turn the two handles 22. The rotation of the handles 22 drives the rotation of the screw 23. The screw 23 and the pressing plate 24 are connected by precise threads, so that the rotation of the screw 23 can be converted into a linear movement of the pressing plate 24. As the pressing plate 24 moves, the limit column 25 slides inside the mounting plate 21, playing a key limiting and supporting role. This design not only ensures the stability of the pressing plate 24 during movement, but also enables the pressing plate 24 to be accurately pressed on the workpiece to clamp and fix the workpiece.
[0028] Working principle: First, place the workpiece to be processed on the upper part of the operating table 1, start the two hydraulic cylinders 15, and the output ends of the two hydraulic cylinders 15 push the movable block 16 to move. The movement of the movable block 16 drives the limit plate 17 to slide outside the limit rod 19. Under the action of the limit plate 17, the movable block 16 drives the connecting rod 20 to move, and the connecting rod 20 drives the mounting plate 21 to move. When the mounting plate 21 drives the pressing plate 24 to move to the upper part of the workpiece, turn the two turning handles 22. The rotation of the turning handle 22 drives the screw 23 to rotate, and the screw 23 drives the pressing plate 24 to move. The movement of the pressing plate 24 drives the limit column 25 to slide inside the mounting plate 21. Under the action of the limit column 25, the pressing plate 24 moves downward to press the workpiece, thereby achieving effective clamping and fixing of the workpiece, preventing the workpiece from shifting during drilling, and ensuring the accuracy of the processed hole position and the hole diameter size. Degrees, next, start the cylinder 2, the output end of the cylinder 2 pushes the push block 3 to move, the push block 3 drives the push plate 4 and the positioning plate 5 to move, the positioning plate 5 drives the positioning seat 8 to move, and the positioning seat 8 drives the right positioning plate 5 and the push plate 4 to move, so that the right push plate 4 drives the slider 26 to slide on the outside of the slide rod 27. When the two positioning plates 5 move, the pulley 7 is driven to slide on the upper part of the guide rail 6. Under the action of the pulley 7 and the slider 26, the positioning seat 8 drives the drill bit 9 to move back and forth on the upper part of the operating table 1. Next, start the motor 11, and the output end of the motor 11 drives the gear 12 to rotate. When the gear 12 rotates, it drives the rack plate 13 to move, and the rack plate 13 drives the drill bit 9 to move left and right outside the positioning seat 8, thereby facilitating the adjustment of the position of the drill bit 9 and guiding it during adjustment, so that the machine tool can handle workpieces of different shapes and sizes, thereby improving the flexibility and applicability of the machine tool.
