Specific embodiments
[0016] The following details the embodiments of the present utility model. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.
[0017] As Figure 1As shown in the figure, a double-hole machine tool specifically includes a base 1, a first drilling component, a second drilling component, and a clamping assembly. The clamping assembly is arranged on the base 1, and the first drilling component and the second drilling component are arranged on both sides of the clamping assembly. 1. The base 1 serves as the support foundation of the entire machine tool, ensuring the stability and overall rigidity of the machine tool, providing a stable platform for installing and supporting the first drilling component, the second drilling component, and the clamping assembly, and guaranteeing the machining accuracy. The mirror design of the first drilling component and the second drilling component enables the drilling operations on both sides to be carried out synchronously, improving the production efficiency. The drilling operations on the workpieces on both sides are carried out respectively. Through their respective independent lifting, rotating, and sliding functions, precise drilling is achieved. The first drilling component includes a fixed table 2, a rotating table 3, a drilling head 4, a sliding block 5, a power motor 6 for driving the drilling head 4 to rotate, and a driving motor 7 for driving the rotating table 3 to rotate. The first drilling component is arranged on a lifting assembly, and the lifting assembly is connected to the base 1. The fixed table 2 is connected to the lifting assembly. The rotating table 3 is rotatably arranged on the fixed table 2. The sliding block 5 is slidably connected to the rotating table 3. The driving motor 7 is installed on the rotating table 3. The drilling head 4 and the power motor 6 are arranged on the sliding block 5. The drilling head 4 is connected to the power motor 6. A sliding driving component is arranged on one side of the sliding block 5. The second drilling component is installed on another identical lifting assembly. The second drilling component is the same as the first drilling component in mirror image. In specific implementation, the fixed table 2 is firmly connected to the lifting assembly, bearing the rotating table 3 and its upper components, serving as the installation foundation of the rotating table 3, and realizing the position adjustment in the vertical direction through the lifting assembly. The rotating table 3 is designed to be rotatable, increasing the flexibility of drilling, supporting the sliding block 5 and the drilling head 4, and realizing the rotational movement through the drive of the driving motor 7 to adapt to the drilling requirements at different angles. The drilling head 4 is connected to the power motor 6 to achieve high-speed rotary drilling and directly carry out drilling processing on the workpiece. The sliding block 5 is slidably connected to the rotating table 3, facilitating the position adjustment in the horizontal direction, carrying the drilling head 4 and the power motor 6, and realizing the horizontal movement on the rotating table 3 through the sliding driving component to meet the drilling requirements at different positions. The power motor 6 provides the high-speed rotary power required by the drilling head 4. The driving motor 7 provides the rotational power for the rotating table 3 to meet the drilling requirements of complex workpieces.
[0018] As Figure 1As shown, on the basis of the above method, further, the lifting component includes a fixed frame body 8, a threaded rod 9 and a rotating handle 10. The fixed frame body 8 is vertically installed on the base 1. The fixed frame body 8 is of a hollow shell structure. The threaded rod 9 is rotatably arranged in the fixed frame body 8, and the rotating handle 10 is arranged at one end of the threaded rod 9. The threaded rod 9 penetrates through the fixed table 2 and is in threaded connection with the internal thread of the fixed table 2. In implementation, the fixed frame body 8 serves as the support structure of the entire lifting component and is vertically installed on the base 1, providing a stable installation environment for the threaded rod 9 and the rotating handle 10. Its hollow shell structure design not only reduces the overall weight but also facilitates the rotation and lifting operations of the threaded rod 9 inside it. The threaded rod 9 matches the threaded holes inside the fixed table 2 through the threads on it. When the threaded rod 9 rotates, it can drive the fixed table 2 to move up and down. Due to the self-locking property of the screw drive, when the threaded rod 9 stops rotating, the fixed table 2 can remain in the current position and will not move easily due to external forces. The rotating handle 10 is used to drive the threaded rod 9 to rotate. By rotating the rotating handle 10, the rotation direction and speed of the threaded rod 9 can be conveniently controlled, so as to accurately adjust the lifting height of the fixed table 2. When the height of the fixed table 2 needs to be adjusted, the user only needs to hold the rotating handle 10 and drive the threaded rod 9 to rotate inside the fixed frame body 8 by controlling the rotation direction and speed of the rotating handle 10. Since the threaded rod 9 matches the threaded holes inside the fixed table 2, the rotation of the threaded rod 9 will drive the fixed table 2 to move up and down.
[0019] As Figure 2As shown, on the basis of the above method, further, the clamping assembly includes a clamping base 11, a connecting frame 12, a chuck 13, a pressing plate 14, a telescopic pressing rod 15 and a first cylinder 16. The clamping base 11 is arranged on the base 1. The chuck 13 is installed on the clamping base 11. The telescopic pressing rod 15 and the first cylinder 16 are arranged on the connecting frame 12. The end of the telescopic pressing rod 15 is connected to the pressing plate 14. The chuck 13, the pressing plate 14, the telescopic pressing rod 15 and the first cylinder 16 are on the same axis. In implementation, the clamping base 11 on the clamping assembly is the basis of the whole clamping assembly. The chuck 13 is installed on the clamping base 11 and is matched with the contact surface of the workpiece to realize the preliminary positioning of the workpiece. The connecting frame 12 serves as a frame for connecting and supporting the telescopic pressing rod 15 and the first cylinder 16, ensuring the stability and accuracy of these components during the clamping process. The telescopic pressing rod 15 is a transmission component connecting the pressing plate 14 and the power source, which is also the first cylinder 16. Driven by the first cylinder 16, the telescopic pressing rod 15 can perform telescopic movement along its axis direction, thereby driving the pressing plate 14 to approach or move away from the workpiece. This design enables the clamping force to be evenly applied to the workpiece, improving the reliability and stability of clamping. When clamping a workpiece, first place the workpiece on the chuck 13 for preliminary positioning. Then, control the first cylinder 16 to generate power, drive the telescopic pressing rod 15 to drive the pressing plate 14 to move towards the workpiece. As the pressing plate 14 gradually approaches, the workpiece is firmly clamped between the chuck 13 and the pressing plate 14, and all components are on the same axis. This design ensures the even distribution of the clamping force and the precise positioning of the workpiece.
[0020] As Figure 3As shown in the figure, on the basis of the above method, further, the sliding driving component includes a second cylinder 17, a driving rod 18 and a connecting rod 19. The second cylinder 17 is installed at one end of the rotating table 3 away from the drilling head 4. The second cylinder 17 is connected to the driving rod 18. The driving rod 18 and the connecting rod 19 are directly connected. The other end of the connecting rod 19 is connected to one side of the sliding block 5. Limit blocks 20 are arranged on the sides of the driving rod 18 and the connecting rod 19. In implementation, the second cylinder 17 is installed at one end of the rotating table 3 away from the drilling head 4 and serves as a power source. Through the telescopic movement, thrust or pulling force is generated to drive the connected components to move. Here, the telescopic movement of the second cylinder 17 will be directly transmitted to the driving rod 18. When the second cylinder 17 expands and contracts, the driving rod 18 will move accordingly, and then the power will be transmitted to the sliding block 5 through the connecting rod 19. The power generated by the second cylinder 17 is converted into the horizontal movement of the sliding block 5. The limit blocks 20 are arranged on the sides of the driving rod 18 and the connecting rod 19. Its main function is to limit the movement range of the sliding block 5 to prevent it from exceeding the predetermined stroke. The limit blocks 20 can be set to be adjustable so as to adjust the maximum movement distance of the sliding block 5 according to the processing requirements. When the position of the sliding block 5 needs to be adjusted, by controlling the telescopic movement of the second cylinder 17, the driving rod 18 moves accordingly, and the power is transmitted to the sliding block 5 through the connecting rod 19, so that it moves horizontally along the surface of the rotating table 3. The limit blocks 20 ensure that the sliding block 5 will not exceed the predetermined range during the movement, thus ensuring the safety and accuracy of the processing.
[0021] In the specific working process of this new double-hole machine tool, based on the design of the double-hole machine tool described above, Preparation stage: Place the workpiece to be processed on the chuck 13 of the clamping assembly. Through the preliminary positioning function of the chuck 13, the workpiece is in a preliminary stable state. Start the first cylinder 16, drive the telescopic pressure rod 15 to extend along its axis, drive the pressure plate 14 to move towards the workpiece until the workpiece is firmly clamped between the chuck 13 and the pressure plate 14. At this time, since all components are on the same axis, it ensures the uniform distribution of the clamping force and the precise positioning of the workpiece. Height adjustment stage: According to the processing requirements, rotate the rotating handle 10 of the lifting assembly to drive the threaded rod 9 to rotate within the fixed frame 8. Since the threaded rod 9 matches the threaded hole inside the fixed table 2, the rotation of the threaded rod 9 will drive components such as the fixed table 2, the rotating table 3, and the drilling head 4 on it to perform lifting motion until the predetermined height position is reached. Drilling preparation stage: Start the driving motor 7 to drive the rotating table 3 to perform a rotational motion, adjust the drilling head 4 to an appropriate angular position to meet the drilling requirements at different angles; at the same time, start the second cylinder 17 to drive the driving rod 18 to move along its axis, and push the sliding block 5 to slide on the rotating table 3 through the connecting rod 19 to adjust the horizontal position of the drilling head 4 so that the drilling head 4 is aligned with the position to be drilled on the workpiece. Drilling operation stage: Start the power motor 6 to drive the drilling head 4 to rotate at a high speed. According to the processing requirements, control the precise movements of the lifting assembly, the rotating table 3, and the sliding block 5, so that the drilling head 4 drills the workpiece at a predetermined speed and depth. Since the first drilling component and the second drilling component are mirror-designed and independent of each other, the drilling operations on both sides can be carried out synchronously, significantly improving the production efficiency. Completion and unloading: After the drilling operation is completed, turn off the power sources such as the power motor 6, the driving motor 7, and the cylinders. By operating the first cylinder 16 in reverse, loosen the clamping of the workpiece by the pressure plate 14, and then remove the workpiece from the chuck 13; repeat the above steps to process the next workpiece; In summary, through the designed clamping assembly, lifting assembly, and sliding drive components, this double-hole machine tool realizes the stable clamping of the workpiece, precise height and position adjustment, and efficient drilling operation, meeting the processing requirements of complex workpieces.
