Description

Technical Field

[0001] This utility model relates to the technical field of ball end mill processing equipment, and in particular to a feeding mechanism for Hitachi ball end mill processing. Background Technology

[0002] "Ball end mill" refers to a tool with a hemispherical cutting edge design, which enables it to efficiently perform three-dimensional surface, contour machining, and groove precision milling. The core advantage of Hitachi Toso ball end mills lies in their use of top-grade ultra-fine particle cemented carbide matrix and advanced coating technology. This combination gives the tool extremely high hardness and toughness, allowing it to effectively resist wear, chipping, and thermal deformation under high-speed, high-load cutting conditions, thereby ensuring the accuracy and consistency of machining dimensions and surface finish.

[0003] Most existing feeding mechanisms share the common limitation of independent, single-step feeding. The feeding action relies on manual operation, requiring operators to frequently switch between the machine tool and the feeding mechanism. This not only increases the burden of repetitive labor but also reduces overall work efficiency, thereby reducing practicality. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings mentioned in the background art by proposing a feeding mechanism for Hitachi ball cutter machining.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A feeding mechanism for machining Hitachi ball cutters includes a fixed sleeve with two guide grooves on its upper surface. A placement plate is fixedly connected to the left side of the fixed sleeve, and a drive motor is fixedly mounted on the upper surface of the placement plate. A drive rod is fixedly connected to the power output end of the drive motor.

[0007] A lead screw is fixedly connected to the right side of the drive rod, a threaded cylinder is threaded to the outer surface of the lead screw, a movable column is fixedly connected to the upper surface of the threaded cylinder, a rotating shaft is movably arranged on the right side of the lead screw, and a fixed plate is movably arranged on the right side of the rotating shaft.

[0008] Preferably, a connecting plate is fixedly connected to the front of the fixed plate, and a limiting rod is fixedly connected to the front of the left side of the connecting plate. A circular cylinder is movably provided on the outer surface of the limiting rod, and a second movable column is fixedly connected to the upper surface of the circular cylinder. The first movable column and the second movable column are located inside the guide groove.

[0009] Preferably, a movable plate is fixedly connected to the upper surface of the first movable column and the second movable column, and a sliding groove is formed on the upper surface of the movable plate.

[0010] Preferably, a clamping plate is fixedly connected to the rear of the upper surface of the movable plate, and six arc-shaped clamping cylinders are fixedly connected to the front of the clamping plate. The inner walls of the six arc-shaped clamping cylinders are all fixedly connected with protective pads.

[0011] Preferably, a second placement plate is fixedly connected to the front of the movable plate, an electric push rod is fixedly installed on the upper surface of the second placement plate, a second drive rod is fixedly connected to the power output end of the electric push rod, a connecting frame is fixedly connected to the rear of the second drive rod, and a second clamping plate is fixedly connected to the rear of the connecting frame.

[0012] Preferably, two sliders are fixedly connected to the lower surface of the clamping plate 2, and the sliders are located inside the groove. Six arc-shaped clamping cylinders 2 are fixedly connected to the rear of the clamping plate 2. Protective pads 2 are fixedly connected to the inner walls of the six arc-shaped clamping cylinders 2. The ball cutter body is provided on the inner side of the six arc-shaped clamping cylinders 1 and 2.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention uses a drive motor to rotate a lead screw, causing the threaded cylinder and its connected movable column one to move. Simultaneously, a fixed plate, connecting plate, and other components drive a movable column two to move, thereby moving the movable plate. Furthermore, an electric push rod can drive the movement of clamping plate two. Through the cooperation of these components, automatic feeding of the ball cutter body can be achieved, reducing manual operation and improving production efficiency. The guide groove guides and limits the movement of movable columns one and two, ensuring the linearity and stability of the movable plate's movement. This allows the ball cutter body to accurately reach the designated position during feeding, improving machining accuracy. At the same time, the cooperation of the sliding groove and the slider also ensures the accuracy of clamping plate two's movement, enabling the arc-shaped clamping cylinders one and two to precisely hold the ball cutter body.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1

[0023] Reference Figure 1-4 A feeding mechanism for machining Hitachi ball cutters includes a fixed sleeve 1, two guide grooves 2 are formed on the upper surface of the fixed sleeve 1, a placement plate 3 is fixedly connected to the left side of the fixed sleeve 1, a drive motor 4 is fixedly installed on the upper surface of the placement plate 3, and a drive rod 5 is fixedly connected to the power output end of the drive motor 4.

[0024] A lead screw 6 is fixedly connected to the right side of the drive rod 5. A threaded cylinder 7 is threadedly connected to the outer surface of the lead screw 6. A movable column 8 is fixedly connected to the upper surface of the threaded cylinder 7. A rotating shaft 9 is movably arranged on the right side of the lead screw 6. A fixed plate 10 is movably arranged on the right side of the rotating shaft 9. The drive motor 4 provides power and drives the lead screw 6 to rotate through the drive rod 5. The rotational motion is converted into the horizontal linear motion of the threaded cylinder 7 by the threaded engagement between the lead screw 6 and the threaded cylinder 7. The movement of the threaded cylinder 7 causes the movable column 8 to slide in the guide groove 2. At the same time, the movable plate 15 links the movable column 14 to move synchronously along the limiting rod 12. Under the dual constraints of the guide groove 2 and the limiting rod 12, the movable plate 15 is guaranteed to move smoothly and linearly, thereby realizing the precise feeding operation of the ball cutter placed on the movable plate 15. The right end of the lead screw 6 is movably connected to the fixed plate 10 through the rotating shaft 9, which not only ensures the stable rotation of the lead screw 6, but also provides support and positioning for the overall structure.

[0025] A connecting plate 11 is fixedly connected to the front of the fixed plate 10. A limiting rod 12 is fixedly connected to the front left side of the connecting plate 11. A circular cylinder 13 is movably disposed on the outer surface of the limiting rod 12. A second movable column 14 is fixedly connected to the upper surface of the circular cylinder 13. The first movable column 8 and the second movable column 14 are located inside the guide groove 2. The fixed plate 10 fixes the limiting rod 12 through the connecting plate 11, providing stable support for the overall structure. The circular cylinder 13 can slide along the limiting rod 12, connect with the second movable column 14 and cooperate with the guide groove 2. Together with the first movable column 8, it constrains the movement trajectory of the moving plate 15, ensuring that it can only move smoothly in a straight line and avoid deviation. This provides structural guarantee for the stability and accuracy of the feeding process.

[0026] A movable plate 15 is fixedly connected to the upper surfaces of movable column 18 and movable column 2 14. A sliding groove 16 is provided on the upper surface of the movable plate 15. Movable column 18 and movable column 2 14 jointly support the movable plate 15, so that the linear motion of the two is directly transmitted to the movable plate 15, driving the components on it to move synchronously. The sliding groove 16 on the movable plate 15 provides a limited trajectory for the movement of subsequent components such as clamping plates, ensuring that the relevant components can slide smoothly in a fixed direction, providing a structural linkage basis for the overall feeding and clamping action.

[0027] A clamping plate 17 is fixedly connected to the rear of the upper surface of the movable plate 15. Six arc-shaped clamping cylinders 18 are fixedly connected to the front of the clamping plate 17. Protective pads 19 are fixedly connected to the inner walls of the six arc-shaped clamping cylinders 18. The clamping plate 17, the arc-shaped clamping cylinders 18, and the protective pads 19 are mainly used to clamp and protect the ball cutter body 26. The clamping plate 17 serves as a support structure, providing a mounting base for the arc-shaped clamping cylinders 18 so that they can be stably placed on the movable plate 15. The six arc-shaped clamping cylinders 18 are straight... The ball cutter body 26 is used to clamp the ball cutter body. Its arc-shaped structure is adapted to the shape of the ball cutter, which can increase the contact area with the ball cutter, thereby providing a more stable clamping force. This ensures that the ball cutter will not shake or fall off during the feeding process, ensuring the accuracy of feeding and the precision of processing. The protective pad 19 is pasted on the inner wall of the arc-shaped clamp 18, which can prevent the clamp from directly contacting the ball cutter and causing scratches or other damage, thus protecting the surface quality of the ball cutter. At the same time, it can also increase the friction and further improve the stability of clamping.

[0028] A second placement plate 20 is fixedly connected to the front of the movable plate 15. An electric push rod 21 is fixedly installed on the upper surface of the second placement plate 20. A second drive rod 22 is fixedly connected to the power output end of the electric push rod 21. A connecting frame 23 is fixedly connected to the rear of the second drive rod 22. A second clamping plate 24 is fixedly connected to the rear of the connecting frame 23. The second placement plate 20 provides stable installation support for the electric push rod 21, ensuring that the position of the power source is fixed. The electric push rod 21, as a power component, can output linear driving force, which is transmitted to the connecting frame 23 through the second drive rod 22. The connecting frame 23 plays the role of force transmission and structural connection, driving the second clamping plate 24 to move synchronously, ultimately realizing the action of the second clamping plate 24 moving closer to or away from the first clamping plate 17, providing controllable power and displacement for clamping and releasing the ball cutter, adapting to the clamping requirements of different specifications of ball cutters.

[0029] Two sliders 27 are fixedly connected to the lower surface of clamping plate 24, and the sliders 27 are located inside the slide groove 16. Six arc-shaped clamping cylinders 25 are fixedly connected to the rear of clamping plate 24. Protective pads 2 are fixedly connected to the inner walls of the six arc-shaped clamping cylinders 25. The ball cutter body 26 is provided on the inner side of the six arc-shaped clamping cylinders 18 and the arc-shaped clamping cylinders 25. The sliders 27 are embedded in the slide groove 16, providing a defined trajectory for the movement of clamping plate 24, ensuring that it can smoothly move closer to or away from clamping plate 17 in a fixed direction. To avoid deviation affecting clamping accuracy, the second arc-shaped clamp 25 and the first arc-shaped clamp 18 are matched and can wrap around the ball cutter body 26 from both sides. The arc-shaped structure that fits the shape of the ball cutter increases the contact area, improves clamping stability, and prevents the ball cutter from shaking during feeding. The second protective pad works together with the first protective pad 19 to avoid damage caused by direct friction between the clamp and the surface of the ball cutter. At the same time, it increases the friction of the contact surface, further strengthens the fixing effect of the ball cutter, and ensures the stability of the ball cutter position and the integrity of the surface during feeding.

[0030] Most existing feeding mechanisms have the common limitation of independent single-step feeding. The feeding action needs to be operated manually. Operators need to frequently switch between the processing machine tool and the feeding mechanism, which not only increases the burden of repetitive labor, but also reduces the overall work efficiency, thereby reducing practicality.

[0031] Place the ball cutter body 26 to be processed inside the arc-shaped clamp 18, ensuring that the position of the ball cutter matches the curvature of the arc-shaped clamp 18. The protective pad 19 contacts the surface of the ball cutter. Activate the electric push rod 21 on the placement plate 20. Its power output end pushes the connecting frame 23 backward through the drive rod 22, causing the clamping plate 24 to move backward along the slide groove 16 and guided by the slider 27. This causes the arc-shaped clamp 25 to gradually approach the arc-shaped clamp 18 until the two cooperate to clamp and fix the ball cutter body 26. The protective pad 2 is in contact with the surface of the ball cutter, completing the clamping and positioning of the ball cutter. Activate the drive motor 4 on the placement plate 3. Its power output end drives the lead screw 6 to rotate through the drive rod 5, connecting with the lead screw 6 by thread. The threaded cylinder 7 moves axially along the lead screw 6, causing the first moving column 8 to slide in the guide groove 2. At the same time, the first moving column 8 drives the second moving column 14 to move synchronously through the moving plate 15, so that the cylindrical cylinder 13 slides along the limiting rod 12. The limiting rod 12 is fixed to the fixed plate 10 through the connecting plate 11, ensuring that the moving plate 15 moves smoothly and linearly, thereby conveying the clamped and fixed ball cutter body 26 to the designated processing position. After processing, the drive motor 4 rotates in reverse, driving the moving plate 15 to reset through the lead screw 6, threaded cylinder 7 and other components. Then the electric push rod 21 retracts, driving the second clamping plate 24 to move forward through the second driving rod 22 and connecting frame 23, releasing the ball cutter body 26, removing the processed ball cutter, and completing one feeding cycle.

[0032] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
