[0014] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following describes in detail the specific embodiments, structures, features, and effects according to the present utility model in conjunction with the attached drawings and preferred embodiments.
[0015] Embodiment 1:
[0016] As Figures 1 - 3As shown in the figure, the utility model discloses a milling groove device for the surface of a cylindrical metal body, which includes a machine frame 1 and a processing platform 2 arranged on the machine frame 1. A clamping mechanism is arranged on the processing platform 2, and the clamping mechanism is used for horizontally clamping the cylindrical metal body. A positioning baffle 18 is arranged on the processing platform 2 at one end of the clamping mechanism. A support frame 3 is arranged on the side of the processing platform 2. An X-axis slide rail 4 is arranged on the support frame 3. A moving frame 5 is arranged on the X-axis slide rail 4, and the moving frame 5 is slidably connected with the X-axis slide rail 4. A Y-axis slide rail 6 is arranged on the lower surface of the moving frame 5. An installation frame 7 is arranged on the Y-axis slide rail 6. A milling groove mechanism 8 is arranged on the installation frame 7. The milling groove mechanism 8 has a Z-axis lifting function. A milling cutter 9 is arranged on the output shaft of the milling groove mechanism 8; A hollow long hole 14 is arranged on the moving frame 5. The long hole 14 is parallel to the Y-axis slide rail 6. An auxiliary slide rail 10 is arranged on the moving frame 5 on the side of the long hole 14. The auxiliary slide rail 10 is parallel to the Y-axis slide rail 6. Two sliders 11 are arranged on the auxiliary slide rail 10. A positioning cylinder 12 vertically downward is arranged on each slider 11. The telescopic end of the positioning cylinder 12 passes through the long hole 14 and extends below the moving frame 5. The two positioning cylinders 12 are respectively located at both ends of the milling groove mechanism 8. A positioning rod 13 is arranged at the telescopic end of the positioning cylinder 12. The diameter of the positioning rod 13 is the same as that of the milling cutter 9. The connecting line of the central axes of the positioning rod 13 and the milling cutter 9 is in the same vertical plane, and this vertical plane is parallel to the Y-axis slide rail 6.
[0017] Among them, the milling groove mechanism 8 is a prior art and has a lifting function. The milling groove mechanism 8 has a Z-axis lifting function, so that the milling cutter 9 descends to contact the workpiece and control the milling groove depth. The milling groove mechanism 8 includes a motor, and the output shaft is driven by the motor to rotate. The milling cutter 9 is arranged on the output shaft, so the milling cutter 9 rotates to complete the milling groove.
[0018] After the clamping mechanism clamps the cylindrical metal body, the axial direction of the cylindrical metal body is the Y-axis direction, that is, the axial direction of the cylindrical metal body is parallel to the Y-axis slide rail 6. Both the X-axis slide rail 4 and the Y-axis slide rail 6 are in a horizontal state and are perpendicular to each other. The Z-axis direction is the direction perpendicular to the horizontal plane, and the lifting of the positioning cylinder 12 is in the Z-axis direction.
[0019] As for the moving frame 5 on the X-axis slide rail 4, the installation frame 7 on the Y-axis slide rail 6, and each slider 11 on the auxiliary slide rail 10, each is driven by a power mechanism to move on the corresponding slide rail. This power mechanism is a prior art and is not specifically limited. The above power mechanisms are not shown in the figure.
[0020] Specifically, the power mechanism adopts a combination of a servo motor and a lead screw nut, which can control a relatively high moving accuracy. For example, a lead screw and a servo motor are arranged in parallel along the X-axis slide rail 4 on the support frame 3, and a nut is arranged on the moving frame 5. The nut is matched with the lead screw. Thus, when the servo motor drives the lead screw to rotate, the moving frame 5 moves along with the nut on the lead screw and the X-axis slide rail 4. The connection form of the mounting frame 7 on the Y-axis slide rail 6 with the combination of the servo motor and the lead screw nut is the same. The connection form of the slider 11 on the auxiliary slide rail 10 with the combination of the servo motor and the lead screw nut is the same. Each slider 11 is connected to the corresponding combination of the servo motor and the lead screw nut, and the two can move independently.
[0021] Specific working process: One end of the cylindrical metal body is abutted against the positioning baffle 18, and it is fixed on the processing platform 2 by using the clamping mechanism. The moving frame 5 on the X-axis slide rail 4 and the mounting frame 7 on the Y-axis slide rail 6 are moved through the power mechanism, so that the milling cutter 9 of the milling groove mechanism 8 is aligned with one end of the processing position of the cylindrical metal body. The milling groove mechanism 8 descends, and the milling cutter 9 performs milling on the cylindrical metal body to form a concave hole. Then the milling groove mechanism 8 ascends, and the milling cutter 9 is withdrawn from the concave hole. The power mechanism drives the mounting frame 7 to move to the other end of the processing position. At this time, the slider 11 located on the same side of the concave hole moves on the auxiliary slide rail 10 to correspond to the concave hole under the action of the power mechanism. At this time, the cylinder 12 on the slider 11 extends downward, so that the positioning rod 13 is inserted into the corresponding concave hole to realize the circumferential positioning of the cylindrical metal body. At this time, the milling groove mechanism 8 can perform milling groove processing on the cylindrical metal body. When milling is close to the concave hole, the slider 11 on the other side moves to the corresponding position of the already milled groove under the action of the power mechanism, and the cylinder 12 produces and inserts the positioning rod 13 into the groove, while the positioning rod 13 in the concave hole moves out of the concave hole under the action of the contraction of the cylinder 12 and moves to the side. The milling groove mechanism 8 can process the remaining groove to complete the entire milling groove work. During the entire milling groove work process, there is a positioning rod 13 for positioning in the concave hole or the groove, so that the circumferential direction of the cylindrical metal body will not be displaced, and thus the axial accuracy of the milling groove processing is high.
[0022] The structure of the clamping mechanism is as follows: Two fixed clamping frames 15 are arranged at intervals on the processing platform 2. Guide slot holes 16 are arranged on the processing platform 2 on the opposite sides of the fixed clamping frames 15. An active clamping frame 17 is arranged in the guide slot holes 16. The lower end of the active clamping frame 17 extends below the processing platform 2. Fixed blocks 19 are arranged at both ends of the guide slot holes 16 below the processing platform 2. A lead screw 20 is rotatably connected between the fixed blocks 19. A threaded hole is arranged at the lower end of the active clamping frame 17. The lead screw 20 passes through the threaded hole and is in mating connection. A motor 21 is arranged on the lower surface of the processing platform 2 at one end of the lead screw 20. The motor 21 is in transmission connection with the lead screw 20.
[0023] The lead screw 20 is rotated by the motor 21, so that the movable clamping bracket 17 moves within the guiding slot hole 16, realizing the clamping or loosening of the cylindrical metal body, and the operation is simple and convenient.
[0024] Both the fixed clamping bracket 15 and the movable clamping bracket 17 exposed above the processing platform 2 are in a V-shaped structure, and the V-shaped openings are arranged oppositely to facilitate the clamping of the cylindrical metal body.
[0025] The X-axis slide rail 4 and the Y-axis slide rail 6 are both in a dovetail structure. The X-axis slide rail 4 and the Y-axis slide rail 6 in the dovetail structure can make the connections between the moving frame 5 and the X-axis slide rail 4, and between the mounting frame 7 and the Y-axis slide rail 6 more firm and stable.
