Technical Field
[0001] The utility model relates to the technical field of drilling devices, in particular to a tailstock drilling device for a numerically controlled lathe. Background Art
[0002] The tailstock of a CNC lathe is one of the key components of the lathe. It is mainly responsible for supporting the workpiece and providing axial positioning. The tailstock structure generally includes a base, a slide, a center, and other parts. The tailstock is a component that supports and positions the workpiece. Its accuracy is crucial to the processing quality of the workpiece. The use of a drilling device can ensure the high precision of the drilling operation and meet the needs of high-precision processing.
[0003] The traditional CNC lathe tailstock drilling device is usually composed of a motor, a drill bit and a control system. When drilling is required, the control system sends instructions to the motor, and the motor drives the drill bit to rotate. At the same time, the tailstock can be accurately controlled by the CNC system, so that the drill bit can be accurately positioned at the position where the hole needs to be drilled. When the drill bit contacts the workpiece, the drilling operation begins. By controlling the feed speed and rotation speed of the drill bit, the depth and diameter of the hole can be accurately controlled.
[0004] However, the position of the drill in the tailstock drilling device of a traditional CNC lathe is fixed. The fixed drill position means that it can only drill holes at specific positions, which is very inconvenient when dealing with diverse workpieces or tasks that require changing the drilling position. Each time the drilling position is changed, the tailstock needs to be readjusted and set up, which greatly increases the complexity and time cost of the operation. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.
[0023] Reference Figure 1 and Figure 2, the utility model provides an embodiment: a CNC lathe tailstock drilling device, including a workbench 1, a sliding block 2 is slidably connected to the side wall of the workbench 1, a motor 3 is fixedly connected inside the workbench 1, a rotating column 4 is fixedly connected to the output end of the motor 3, a sliding column 5 is fixedly connected to the upper surface of the rotating column 4, a sliding block 2 is fixedly connected to the upper surface of the sliding block 2, a supporting plate 7 is slidably connected to the sliding block 26, a slide groove 8 is opened inside the supporting plate 7, the sliding column 5 is slidably connected inside the slide groove 8, a motor 2 9 is fixedly connected inside the workbench 1, a rotating column 2 10 is fixedly connected to the output end of the motor 2 9, a sliding column 2 11 is fixedly connected to the upper surface of the rotating column 2 10, a slide groove 24 is opened inside the support plate 7, the sliding column 2 11 is slidably connected inside the slide groove 24, a motor 3 12 is fixedly connected to the side wall of the support plate 7, a drill bit 13 is fixedly connected to the output end of the motor 3 12, and a support component is arranged on the upper surface of the workbench 1;
[0024] Specifically, the motor 13 is used as a power source, and drives the rotating column 14 to rotate through its output end. The rotation of the rotating column 14 will further drive the sliding column 15 to slide inside the slide groove 8. As the sliding column 15 slides, the support plate 7 will drive the sliding block 2 to slide back and forth on the side wall of the workbench 1, thereby achieving precise adjustment of the distance between the drill bit 13 and the workpiece. After completing the preliminary adjustment of the distance, the motor 29 needs to be started next. The output end of the motor 29 will drive the rotating column 210 to rotate, and the rotation of the rotating column 210 will drive the sliding column 211 to slide in the slide groove 2 24 is slid inside. The purpose of this step is to make the support plate 7 slide left and right inside the sliding block 2 6, so as to realize the processing of different positions of the workpiece. Through the above steps, we have completed the position adjustment of the drill bit 13 in different directions. Finally, the drill bit 13 is driven to rotate through the output end of the motor 3 12, so as to realize the precise processing of the workpiece. Through the coordinated work of these components, we can realize the precise adjustment of the position of the drill bit 13, so as to realize the high-precision processing of the workpiece. The wide application of this technology not only improves the efficiency and quality of industrial manufacturing.
[0025] Reference Figure 1 and Figure 3 The support assembly includes a support block 14, which is fixedly connected to the upper surface of the workbench 1, a hollow plate 15 is fixedly connected to the side wall of the support block 14, a fixed plate 16 is fixedly connected to the inner wall of the hollow plate 15, a cylinder 17 is fixedly connected to the side wall of the fixed plate 16, a connecting block 18 is fixedly connected to the output end of the cylinder 17, and hollow blocks 19 are fixedly connected to both sides of the connecting block 18;
[0026] Specifically, one of the core components of the support assembly is the support block 14. This solid component is fixedly connected to the upper surface of the workbench 1, providing a solid foundation for the entire assembly. The side wall of the support block 14 is fixedly connected with a hollow plate 15, which is a key connecting component and is tightly fixed to the support block 14 to ensure the overall stability and reliability of the assembly. The role of the hollow plate 15 is to connect key components such as the fixed plate 16 and the cylinder 17 together to form a complete support system. The fixed plate 16 is another important component in the support assembly. It is fixedly connected to the inner wall of the hollow plate 15 and plays a supporting and solid role. The function of the fixed cylinder 17 is to have certain rigidity and stability. The cylinder 17 is the power source in the support assembly. It is connected to the hollow block 19 through the connecting block 18 at the output end. The cylinder 17 is equipped with components such as a piston and a spring. The compressed air is used to generate thrust or tension, thereby driving the connecting block 18 and the hollow block 19 to move. The connecting block 18 is a connecting component between the cylinder 17 and the hollow block 19. It is fixedly connected to the output end of the cylinder 17. The hollow blocks 19 are fixedly connected on both sides of the connecting block 18. Their function is to transfer the power generated by the cylinder 17 to the entire support assembly to achieve the required support and movement functions.
[0027] Reference Figure 1 and Figure 3 The hollow block 19 is rotatably connected with a rotating plate 20, the side wall of the cylinder 17 is fixedly connected with a fixed block 22, the side wall of the fixed block 22 is fixedly connected with a slide rail 23, the side wall of the slide rail 23 is slidably connected with a clamping block 21, the rotating plate 20 is rotatably connected inside the clamping block 21, the clamping block 21 is slidably connected to the side wall of the fixed block 22, and there are four clamping blocks 21 in total;
[0028] Specifically, the movement of the hollow block 19 is not just a simple action, it affects the entire body and triggers a series of chain reactions. When the hollow block 19 moves along the preset path, it first forms a close linkage relationship with the rotating plate 20, which cleverly utilizes the lever and transmission mechanism in the physical principle, so that the slight movement of the hollow block 19 can drive the rotating plate 20 to rotate at a corresponding angle. As the rotating plate 20 rotates, it further interacts with the clamping block 21 on the side wall of the slide rail 23. The clamping block 21 not only fixes the workpiece, but more importantly, since there are four clamping blocks 21 in the entire system, the positions of these four clamping blocks 21 on the side wall of the slide rail 23 are carefully designed, and they can work together to ensure that no matter how the size of the workpiece changes, it can be firmly fixed, which not only improves the clamping stability of the workpiece, but also greatly enhances the adaptability and flexibility of the mechanical system.
[0029] Working principle: When the workpiece needs to be fixed during processing, the connecting block 18 is first pushed to move through the output end of the cylinder 17. The movement of the connecting block 18 will drive the hollow block 19 to move, and the movement of the hollow block 19 will drive the rotating plate 20 to rotate. The rotation of the rotating plate 20 will drive the clamping block 21 to slide on the side wall of the slide rail 23. Since there are four clamping blocks 21, the workpiece can be firmly fixed and can be adapted to workpieces of different sizes. At this time, the clamping and fixing of the workpiece is completed. When the drill bit 13 is used to process the workpiece and the position of the drill bit 13 needs to be moved, the rotating column 4 is first driven to rotate through the output end of the motor 3. The rotation of column 14 will drive sliding column 15 to slide inside slide groove 18, and the sliding of sliding column 15 will cause support plate 7 to drive sliding block 12 to slide back and forth on the side wall of workbench 1, adjust the distance between drill bit 13 and workpiece, and then start the output end of motor 29 to drive rotating column 210 to rotate, and the rotation of rotating column 210 will drive sliding column 211 to slide inside slide groove 24, and the sliding of sliding column 211 will drive support plate 7 to slide left and right inside sliding block 26, which can be used to process different positions of the workpiece. At this time, the movement of drill bit 13 to different positions is completed, and the drill bit 13 is driven to rotate by the output end of motor 3 12 to process the workpiece.
[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
