Technical Field

[0001] This utility model relates to the field of CNC drilling and grooving machine technology, and in particular to a CNC drilling and grooving machine for aluminum alloy parts. Background Technology

[0002] Hollowed-out aluminum alloy parts are common mechanical parts. These parts are used in environments where sufficient strength is guaranteed while minimizing overall weight. They are generally used when there are strict requirements for the overall quality of the equipment. The processing of aluminum alloy parts requires the use of CNC drilling and grooving machines. CNC drilling and grooving machines are mainly used for drilling, reaming, chamfering, and other processing, and are mainly used in the automotive, mold, shipbuilding, aerospace, and engineering machinery industries.

[0003] Currently, when CNC drilling and grooving machines groove hollow cylindrical workpieces, they typically use two parallel clamps to hold the workpiece. However, this method may cause the hollow cylindrical workpiece to deform due to the application of large forces, which in turn affects the processing effect of the cylindrical workpiece.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] Reference Figure 1-4A CNC drilling and grooving machine for aluminum alloy parts includes a grooving machine body 1. A support base 5 is provided on the outer side of the grooving machine body 1. A worktable 3 is rotatably mounted on the top of the support base 5. A transmission box 14 is fixedly mounted on the top of the worktable 3. A support column 8 is fixedly mounted on the side of the transmission box 14 away from the worktable 3. Fixed grooves 9 are equidistantly formed on the outer periphery of the support column 8. A double-acting lead screw 10 is rotatably connected inside each fixed groove 9. Moving parts 13 are threadedly connected to both ends of the outer side of the double-acting lead screw 10. Connecting elements 13 are rotatably connected to the outer side of each moving part 13. The connecting rod 12 has a contact member 11 rotatably mounted between the two connecting rods 12. The moving parts 13 are slidably connected to the inner wall of the fixed groove 9. When slotting the hollow cylindrical workpiece, the rotation of the bidirectional lead screw 10 can drive the two moving parts 13 to move in opposite directions. Then, with the help of the connecting rod 12, each contact member 11 can be pushed outward to be inserted into the hollow cylindrical workpiece to support the surface of the hollow cylindrical workpiece, thereby reducing the deformation of the workpiece and ensuring the processing effect of the cylindrical workpiece.

[0029] Specifically, a steering assembly is provided at the bottom of the support base 5. The steering assembly includes a gear b19 located at the bottom of the support base 5. The rotation shaft of the worktable 3 passes through the interior of the support base 5. The rotation of gear b19 drives gear a18 to rotate, which in turn drives the worktable 3 to rotate. This allows the workpiece outside the support column 8 to perform circumferential motion, thereby increasing the grooving range of the workpiece. Gear a18 is fixedly connected to the worktable, and gear a18 meshes with gear b19. A lateral movement assembly is provided on the outer side of the grooving machine body 1. The lateral movement assembly includes two electrically driven slides fixedly installed on one side of the grooving machine body 1. The outer side of the electric slide rail 6 is slidably mounted with sliders 7. The operation of the electric slide rail 6 can drive the sliders 7 to move, thereby driving the support base 5 and the workpiece to move horizontally, so as to be suitable for grooving purposes in different positions. The sliders 7 are all fixedly installed on the outer side of the support base 5. The drive gear 16 is rotatably connected to the center of the transmission box 14. The rotation of the drive gear 16 can drive multiple driven gears 17 to rotate. One end of the bidirectional lead screw 10 extends into the interior of the transmission box 14 and is fixedly connected to the driven gears 17. The driven gears 17 are all meshed with the drive gears 16.

[0030] Specifically, a servo motor 15 is fixedly installed inside the transmission box 14. The output shaft of the servo motor 15 is fixedly connected to the rotation shaft of the drive gear 16. The rotation of the output shaft of the servo motor 15 can drive the drive gear 16 to rotate. Rubber strips are fixedly connected at equal intervals to the outer side of the contact member 11. A drilling device 2 is installed inside the grooving machine body 1. A bracket 4 is fixedly installed on the outer side of the support base 5, which can provide better support for the support base 5. A drive motor 20 is fixedly installed on one side of the bracket 4. The output shaft of the drive motor 20 is fixedly connected to the central shaft of the gear b19 so as to provide a power source for the gear b19.

[0031] Working principle: First, the operator can place the hollow cylindrical workpiece on the outer periphery of the support column 8. Then, the servo motor 15 is started by the external controller to drive the drive gear 16 to rotate. The rotation of the drive gear 16 drives multiple driven gears 17 to rotate, which in turn drives the corresponding bidirectional lead screw 10 to rotate. Subsequently, the two moving parts 13 move in opposite directions. Then, with the help of the connecting rod 12, the various abutting parts 11 can be pushed outward to insert into the hollow cylindrical workpiece to support the surface of the hollow cylindrical workpiece. The rotation of the output shaft of the drive motor 20 drives the gear b19 to rotate, which in turn drives the gear a18 to rotate, which in turn drives the worktable 3 to rotate. This allows the workpiece outside the support column 8 to perform circumferential motion, thereby increasing the grooving range of the workpiece. Furthermore, the operation of the electric slide rail 6 drives the slider 7 to move, which in turn drives the support base 5 and the workpiece to move horizontally, thus making it suitable for grooving purposes in different positions.
