Description

Technical Field

[0001] This application relates to the technical field of lathes, and in particular to a multi-functional CNC lathe. Background Technology

[0002] A lathe is a machine tool that performs cutting operations by rotating a workpiece and using a cutting tool. It is widely used in the processing of materials such as metal, wood, and plastic.

[0003] In related technologies, reference can be made to Chinese utility model patent CN209094555U, which discloses a simple lathe for turning. Its structure includes a body, a stand, a moving frame, a gear plate, a fixture, and a tool post. The stand is located at the bottom of the body and is welded to the body. A gear plate is located on the left side of the body and is rotatably connected to the fixture via a chain. A fixed seat is located on the right side of the body and is detachably connected to the body via a nut. A tailstock is located on the fixed seat. A positioning pin is located on the left side of the tailstock, and a circular adjusting disc is located on the right side of the tailstock. The adjusting disc is rotatably connected to the tailstock. A moving frame is located in the middle of the body, and a tool post is located on the moving frame. A moving crank is located on the right side of the tool post and is rotatably connected to the moving frame. A moving groove is located on the fixture.

[0004] However, the aforementioned lathes can only perform cutting operations in a single direction on the workpiece using the tool post, resulting in a relatively simple machining method that cannot meet the needs of complex processes. Utility Model Content

[0005] In order to improve the adaptability of lathes to different machining requirements of workpieces, this application provides a multi-functional CNC lathe.

[0006] This application provides a multi-functional CNC lathe, which adopts the following technical solution:

[0007] A multi-functional CNC lathe includes a machine body, on which a chuck and a rotary motor for driving the chuck to rotate are rotatably mounted. A first worktable and a second worktable are horizontally slidable along the axial direction of the chuck's rotation axis on the machine body. The machine body is provided with a first driving mechanism and a first limiting mechanism. The first driving mechanism is used to drive the first worktable to move horizontally, and the first limiting mechanism is used to limit the sliding position of the second worktable. The first worktable is located between the chuck and the second worktable. Two third worktables are horizontally slidable along the axial direction perpendicular to the chuck's rotation axis on the first worktable. The two third worktables are located on both sides of the chuck in the horizontal direction. Two sets of second driving mechanisms are provided on the first worktable, which are used to drive the two third worktables to move respectively. Different types of cutting tools or drilling tools are respectively mounted on the first, second, and third worktables.

[0008] By adopting the above technical solution, a first worktable and a second worktable are slidably installed on the machine body, and two third worktables are slidably installed on the first worktable. Then, by installing different types of cutting tools or drills on the first worktable, the workpiece on the chuck can be processed in different ways from three different directions, which meets the diverse processing needs of the workpiece and greatly improves the lathe's adaptability to different processing requirements of the workpiece.

[0009] Optionally, the first drive mechanism includes:

[0010] A first drive motor is mounted on a first worktable;

[0011] A drive rack, which is mounted on the machine body;

[0012] A drive gear is mounted on the output shaft of a first drive motor and meshes with a drive rack.

[0013] By adopting the above technical solution, the first drive motor starts and drives the drive gear to rotate. The rotation of the drive gear can drive the first worktable to move along the length of the drive rack, thereby realizing the horizontal movement of the first worktable by controlling the first drive motor.

[0014] Optionally, the first limiting mechanism includes:

[0015] The first limiting plate is mounted on the machine body, and a plurality of first limiting holes are evenly distributed on the first limiting plate along the sliding direction of the second worktable.

[0016] The second limiting plate is disposed on the second worktable, and the second limiting plate is provided with a second limiting hole;

[0017] A limiting screw is provided, with a thread inside the second limiting hole. The limiting screw is threadedly connected to the second limiting hole and its bottom passes through the first limiting hole.

[0018] By adopting the above technical solution, a first limiting plate is installed on the machine body, and a second limiting plate is installed on the second worktable. By turning the limiting screw to disengage from the first limiting hole, the position of the second worktable can be moved freely. This allows adjustment of the position of the cutting tools or drills on the second worktable, ensuring that the cutting tools or drills on the second worktable can meet the processing requirements of the workpiece. After the second worktable is moved to the target position, turning the limiting screw causes the bottom of the limiting screw to insert into the first limiting hole, thereby limiting the relative position between the first limiting plate and the second limiting plate, thus fixing the position of the second worktable.

[0019] Optionally, the second drive mechanism includes:

[0020] A drive block is slidably disposed on a first worktable, and a third worktable is disposed on the drive block;

[0021] A drive screw is rotatably mounted on the first worktable and is threadedly connected to a drive block;

[0022] A drive motor is mounted on the first worktable and its output shaft is connected to a drive screw.

[0023] By adopting the above technical solution, the drive motor starts and drives the drive screw to rotate, the drive screw rotates and drives the drive block to move, and the drive block moves and drives the third worktable to move, thus realizing the movement of the third worktable by controlling the drive motor.

[0024] Optionally, a dust cover is provided on the third worktable to cover the space above the drive screw.

[0025] By adopting the above technical solution, a dust cover is installed on the third workbench. The dust cover covers the space above the drive screw, thereby reducing the probability of debris generated during workpiece processing and dust and other impurities in the environment entering the drive screw, ensuring the long-term and durable transmission effect of the drive screw.

[0026] Optionally, a movable block is slidably disposed on the third worktable along the sliding direction of the third worktable, a movable electric cylinder is disposed on the third worktable, the piston rod of the movable electric cylinder is connected to the movable block, a fourth worktable is disposed on the movable block, and a drilling tool is mounted on the fourth worktable.

[0027] By adopting the above technical solution, a moving electric cylinder and a moving block are installed on the third worktable, and then a fourth worktable is installed on the moving block. By controlling the moving electric cylinder, the fourth worktable can be moved, thereby enabling the drill bit on the fourth worktable to process the workpiece, further improving the overall workpiece processing capability of the drilling machine.

[0028] Optionally, a dustproof baffle is provided on the first workbench, which shields the space above the drive rack and the lateral space on the side with the teeth.

[0029] By adopting the above technical solution, a dustproof baffle is installed on the first worktable to shield the drive rack, thereby reducing the probability of debris generated during workpiece processing and dust and other impurities in the environment entering the meshing teeth of the drive rack, ensuring a long-lasting and durable transmission effect between the drive rack and the drive gear.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. By sliding and mounting the first and second worktables on the machine body, and sliding and mounting two third worktables on the first worktable, and then by mounting different types of cutting tools or drills on the first, second and third worktables respectively, different types of machining work can be performed on the workpieces on the chuck from three different directions, which meets the diverse machining needs of the workpieces and greatly improves the lathe's adaptability to different machining requirements of the workpieces.

[0032] 2. By installing a dust cover on the third workbench, the dust cover covers the space above the drive screw, thereby reducing the probability of debris generated during workpiece processing and dust and other impurities in the environment entering the drive screw, ensuring the long-lasting transmission effect of the drive screw.

[0033] 3. By installing a dustproof baffle on the first worktable to shield the drive rack, the probability of debris generated during workpiece processing and dust and other impurities in the environment entering the meshing teeth of the drive rack is reduced, ensuring a long-lasting and durable transmission effect between the drive rack and the drive gear.

[0038] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail.

[0039] This application discloses a multi-functional CNC lathe.

[0040] Reference Figure 1 and Figure 2 The multi-functional CNC lathe includes a machine body 1, on which a chuck 11 and a rotary motor 12 for driving the chuck 11 to rotate are rotatably mounted. A first worktable 13 and a second worktable 14 are horizontally slidably mounted on the machine body 1 along the axial direction of the chuck 11's rotation axis. A first drive mechanism 2 and a first limiting mechanism 3 are provided on the machine body 1. The first drive mechanism 2 is used to drive the first worktable 13 to move horizontally, and the first limiting mechanism 3 is used to limit the sliding position of the second worktable 14. The first worktable 13 is located between the chuck 11 and the second worktable 14.

[0041] Reference Figure 2 and Figure 3 The first drive mechanism 2 includes a first drive motor 21, a drive rack 22, and a drive gear 23. The first drive motor 21 is fixedly mounted on the upper surface of the first worktable 13. The drive rack 22 is fixedly mounted on the machine body 1 located below the first worktable 13. The drive gear 23 is rotatably mounted on the lower surface of the first worktable 13 and connected to the output shaft of the first drive motor 21, and the drive gear 23 meshes with the drive rack 22.

[0042] Reference Figure 3 When the first drive motor 21 starts, it drives the drive gear 23 to rotate. The rotation of the drive gear 23 can drive the first worktable 13 to move along the length of the drive rack 22. Thus, by controlling the first drive motor 21, the horizontal movement of the first worktable 13 is achieved.

[0043] Reference Figure 1 and Figure 2 The first limiting mechanism 3 includes a first limiting plate 31, a second limiting plate 32, and a limiting screw 33. The first limiting plate 31 is fixedly installed on the machine body 1 located below the second worktable 14. The second limiting plate 32 is fixedly installed on the lower surface of the second worktable 14. A plurality of vertical first limiting holes 34 are evenly distributed on the upper surface of the first limiting plate 31 along the sliding direction of the second worktable 14. A second limiting hole is formed on the second limiting plate 32, penetrating the second limiting plate 32. A thread is formed in the second limiting hole, and the limiting screw 33 is threadedly connected to the second limiting hole, with its bottom end passing through the first limiting hole 34.

[0044] Reference Figure 2By turning the limiting screw 33 to disengage it from the first limiting hole 34, the position of the second worktable 14 can be freely moved. This allows adjustment of the position of the cutting tools or drills on the second worktable 14, ensuring they meet the processing requirements of the workpiece. After the second worktable 14 is moved to the target position, turning the limiting screw 33 causes its bottom to insert into the first limiting hole 34, thus limiting the relative position between the first limiting plate 31 and the second limiting plate 32, thereby fixing the position of the second worktable 14.

[0045] Reference Figure 2 Two third worktables 15 are horizontally slidably mounted on the first worktable 13 along an axis perpendicular to the rotation axis of the chuck 11. The two third worktables 15 are located on both sides of the chuck 11 in the horizontal direction. Two sets of second drive mechanisms 4 are provided on the first worktable 13, which are used to drive the two third worktables 15 to move. Different types of cutting tools or drills are mounted on the first worktable 13, the second worktable 14, and the third worktable 15.

[0046] Reference Figure 2 and Figure 3 The second drive mechanism 4 includes a drive block 41, a drive screw 42, and a drive motor 43. The drive block 41 is slidably mounted on the upper surface of the first worktable 13. The third worktable 15 is fixedly mounted on the upper surface of the drive block 41. The drive screw 42 is rotatably mounted on the first worktable 13 and threadedly connected to the drive block 41. The drive motor 43 is fixedly mounted on the upper surface of the first worktable 13, and its output shaft is connected to the drive screw 42. When the drive motor 43 starts, it drives the drive screw 42 to rotate. The rotation of the drive screw 42 drives the drive block 41 to move. The movement of the drive block 41 drives the third worktable 15 to move, thus realizing the movement of the third worktable 15 by controlling the drive motor 43.

[0047] Reference Figure 3 A movable block 44 is slidably mounted on the third worktable 15 along its sliding direction. A movable electric cylinder 45 is fixedly mounted on the upper surface of the third worktable 15. The piston rod of the movable electric cylinder 45 is connected to the movable block 44. A fourth worktable 16 is fixedly mounted on the upper surface of the movable block 44, and a drill bit is mounted on the fourth worktable 16. By controlling the movable electric cylinder 45, the fourth worktable 16 can be moved, thereby enabling the drill bit on the fourth worktable 16 to perform workpiece processing, further improving the overall workpiece processing capability of the drilling machine.

[0048] Reference Figure 1A dustproof baffle 17 is fixedly installed on the side wall of the first workbench 13, which shields the space above the drive rack 22 and the lateral space on the side with the meshing teeth. A dustproof cover 18 is fixedly installed on the side wall of the third workbench 15, which covers the space above the drive screw 42.

[0049] The working principle of this application embodiment is as follows:

[0050] The first worktable 13 and the second worktable 14 are slidably mounted on the machine body 1, and two third worktables 15 are slidably mounted on the first worktable 13. Then, a fourth worktable 16 is mounted on the third worktables 15. By installing different types of cutting tools or drills on the first worktable 13, the second worktable 14, the third worktable 15 and the fourth worktable 16 respectively, different types of machining workpieces on the chuck 11 can be completed from three different directions, which meets the diverse machining needs of workpieces and greatly improves the lathe's adaptability to different machining requirements of workpieces.
