[0045] The present application will be further described in detail below with reference to the accompanying drawings.

[0046] This application discloses a miniature lathe, such as... Figure 1 As shown, the assembly includes: a first profile 1; a clamping device 2 and a tailstock device 3, both detachably mounted on the first profile 1; the clamping device 2 and the tailstock device 3 are arranged in a straight line and spaced apart; the clamping device 2 is provided with a connecting rod 20 and a clamping member 21; the clamping member 21 is connected to the end of the connecting rod; the clamping member 21 and the tailstock device 3 are used to fix both ends of the workpiece; a transmission assembly 4 is connected to the connecting rod 20 and is used to drive the connecting rod 20 to rotate, thereby driving the clamping member 21 to rotate; a cutting assembly 5 is detachably mounted on the first profile 1 and located between the clamping device 2 and the tailstock device 3; the cutting assembly 5 is used to cut the workpiece.

[0047] In use, the first profile 1 is placed horizontally, and the clamping device 2 and the tailstock device 3 are respectively installed at both ends of the first profile 1; the cutting device is installed on the side wall of the first profile 1, and is located between the clamping device 2 and the tailstock device 3; finally, the transmission assembly 4 is installed and connected to the connecting rod 20. Specifically, when turning the workpiece, the workpiece is clamped with the clamping device 21, the transmission assembly 4 is started, and the connecting rod 20 is driven to rotate, so as to drive the two workpieces to rotate along their own axis; then, the cutting assembly 5 is moved to turn the workpiece.

[0048] In one embodiment, the miniature lathe also includes a base 6, which can be placed horizontally during use. The first profile 1 is screwed onto the base 6 to increase the overall stability of the lathe during turning. In this embodiment, the clamping device 2, tailstock device 3, transmission assembly 4, and cutting assembly 5 of the miniature lathe adopt a lightweight and detachable design. After disassembly, all parts of the miniature lathe can be placed in a toolbox, making it portable for travel, work, and study. When there is a need for miniature machining parts, the various modules can be flexibly assembled for quick deployment, responding to small parts machining needs at any time, and the operation is simple and easy to learn.

[0049] In this embodiment, as Figure 1 and Figure 2 As shown, the clamping member 21 is a three-jaw chuck; the clamping device 2 also includes a second profile member 22; the second profile member 22 is detachably connected to the first profile member 1 through a profile fixing member; a through hole is provided on the center line of the second profile member 22; a bearing is provided at the end of the through hole; one end of the connecting rod 20 passes through the through hole and extends out of the bearing to be screwed to the three-jaw chuck.

[0050] Specifically, in actual use, the second profile 22 is installed at one end of the first profile 1 via a profile fixing component. A through hole is provided on the center line of the second profile 22, and the connecting rod 20 passes through the through hole and is screwed to a three-jaw chuck. The three-jaw chuck clamps the workpiece, and the transmission assembly 4 is connected to the end of the connecting rod 20 opposite to the three-jaw chuck. When the transmission assembly 4 drives the connecting rod 20 to rotate, it drives the three-jaw chuck to rotate, thereby driving the workpiece to rotate. In this embodiment, both ends of the connecting rod 20 are provided with roller bearings to reduce friction during rotation, making the rotation smoother; at the same time, it prevents displacement during rotation of the connecting rod 20, ensuring that the connecting rod 20 always rotates within its axial position range.

[0051] In another embodiment of this utility model, such as Figure 3As shown, the transmission assembly 4 includes: a DC motor 40; a first synchronous pulley 41 connected to the output shaft of the DC motor 40; a second synchronous pulley 42 connected to the end of the connecting rod 20 facing away from the clamping member 21; and a synchronous belt 43 connecting the first synchronous pulley 41 and the second synchronous pulley 42.

[0052] Specifically, in actual use, the first synchronous pulley 41 is connected to the output shaft of the DC motor 40 by screw fixing, and the second synchronous pulley 42 is connected to the end of the connecting rod 20 away from the three-jaw chuck by screw fixing. The first synchronous pulley 41 and the second synchronous pulley 42 are connected by a synchronous belt 43. When the DC motor 40 is started, the DC motor 40 drives the first synchronous pulley 41 to rotate, and the synchronous belt 43 drives the second synchronous pulley 42 to rotate, thereby driving the connecting rod 20 to rotate, so that the three-jaw chuck clamps the workpiece and rotates it, so as to turn the workpiece into the target shape in different directions.

[0053] In this embodiment, the drive system is fixed using screws, allowing for easy adjustment of the connecting rod 20's rotational speed by replacing the first synchronous pulley 41 and the second synchronous pulley 42 with different tooth counts. This adapts to the processing needs of various materials such as metal, plastic, and wood, simplifying the equipment adjustment process and eliminating the need to replace the motor or introduce a complex control system. Compared to the traditional servo motor drive mode, the synchronous belt 43 transmission system in this embodiment uses standardized components, reducing manufacturing costs and simplifying disassembly and assembly, thus minimizing downtime. Maintenance is also convenient and requires no specialized tools.

[0054] In this embodiment, as Figure 1 and Figure 3 As shown, the transmission assembly 4 also includes a third profile 44, which is detachably connected to the second profile 22 via a profile fixing member; the DC motor 40 is fixedly mounted on the third profile 44.

The tailstock device 3 also includes a first handwheel 35; the first handwheel 35 is connected to the end of the bolt 32 opposite to the tip 34.

[0056] The fourth profile 31 is mounted on the first profile 1 at one end away from the second profile 22 via a profile fixing component. A screw hole 33 is provided on the center line of the fourth profile 31, and a bolt 32 is screwed into the screw hole 33 and passes through the screw hole 33. One end of the bolt 32 extending out of the screw hole 33 is connected to the center point 34, and the other end is connected to the first handwheel 35. The screw hole 33 is coaxially arranged with the through hole provided on the second profile 22. When the connecting rod 20 drives the three-jaw chuck to rotate, the three-jaw chuck clamps the workpiece and rotates synchronously. By rotating the first handwheel 35, the bolt 32 drives the center point 34 to rotate and move towards the workpiece to cooperate with the three-jaw chuck to fix the workpiece and prevent the workpiece from falling off during turning.

[0057] In this embodiment, as Figure 3 As shown, one end of the bolt 32 is recessed inward to form a connecting groove; the tailstock device 3 also includes a bearing; the outer ring of the bearing is disposed on the side wall of the connecting groove; the inner ring is disposed on the center point 34. Specifically, in actual use, the bolt 32 is an M12 bolt 32. One end of the M12 bolt 32 is hollowed out to form a connecting groove, and then the bearing is embedded in the connecting groove. Subsequently, the center point 34 is inserted into the inner ring of the bearing to ensure that the center point 34 rotates synchronously with the workpiece, avoiding sliding friction between the center point 34 and the workpiece, which would affect the stability of the workpiece.

At the same time, the first rotating rod 55 is screwed to the screw hole 33, and one end of the first rotating rod 55 is connected to the first support member 52, and the other end passes through the second support member 53 and is provided with a second handwheel 51. Specifically, when the second handwheel 51 is rotated, the first rotating rod 55 drives the first slider 50 to move along the horizontal axis of the first profile member 1, so as to turn the workpiece in the horizontal axis direction of the workpiece. In this embodiment, there are two fixing rods 54, which are respectively inserted at both ends of the first slider 50. The first rotating rod 55 is set on the center line of the first slider 50 to ensure that when the first rotating rod 55 rotates, the first slider 50 can only move along the horizontal axis of the first profile 1, thus ensuring effective machining of the parts.

[0060] In this embodiment, the cutting assembly 5 further includes: a second slider 56, which is slidably disposed on the first slider 50; the second slider 56 is provided with a screw hole 33; a second rotating rod 57, which is screwed to the second slider 56 and passes through the screw hole 33; wherein the second rotating rod is perpendicular to the first rotating rod 55; rotating the second rotating rod 57 causes the second slider 56 to move along the longitudinal axis of the first profile 1.

[0061] In use, the second slider 56 is slidably mounted on top of the first slider 50. A screw hole 33 is provided on the center line of the second slider 56. The second rotating rod 57 is screwed into the screw hole 33, and one end of the second rotating rod 57 extends out of the screw hole 33 and is provided with a third handwheel 58. When the third handwheel 58 is rotated, the second rotating rod 57 is driven to rotate, thereby driving the second slider 56 to move along the longitudinal axis of the first profile 1, and turning the workpiece in the longitudinal axis direction of the workpiece.

[0062] In this embodiment, the cutting assembly 5 further includes a cutting blade; the cutting blade 59 is screwed to the second slider 56 and is used to cut the workpiece.
