Description

Technical Field

[0001] This utility model belongs to the field of processing equipment technology, specifically relating to an additive manufacturing miniature lathe. Background Technology

[0002] In the field of machining, miniature lathes are widely used in the turning of precision parts, such as watch parts and electronic components, due to their advantages of high precision and small size. However, traditional miniature lathes only have a single subtractive machining function, which removes material from the workpiece by cutting with a cutting tool. They can only process raw materials into relatively simple rotating parts, and have limitations in processing parts with complex internal structures and irregular curved surfaces, making it difficult to meet the current diverse and complex design and manufacturing needs of precision parts.

[0003] In recent years, additive manufacturing technology has attracted much attention due to its ability to create complex structural parts by layer-by-layer material deposition. However, existing additive manufacturing equipment is independent of traditional lathes. When producing parts that require both additive manufacturing and turning, the workpiece often needs to be transferred between different machines. This not only increases processing steps and time costs but also easily introduces errors due to multiple clamping and positioning, affecting the machining accuracy and quality of the parts. In addition, independent equipment occupies a large production space, which is not conducive to improving production efficiency and reducing production costs. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an additive manufacturing micro lathe to solve the processing limitations of existing lathes. This utility model patent designs an additive manufacturing micro lathe that combines additive manufacturing technology with a micro lathe, enabling a single device to perform both additive manufacturing and subtractive processing functions.

[0005] This utility model discloses an additive manufacturing micro lathe, comprising a lathe body, a controller, an X-axis servo motor, a Y-axis servo motor, an X-axis lead screw, a Y-axis lead screw, a tailstock, a tailstock center, an intermediate seat, a four-tool holder, a rotary drive motor, an additive manufacturing raw material extrusion module, an extrusion tube, an additive manufacturing heater, an additive manufacturing nozzle, and a self-centering chuck. The X-axis lead screw is rotatably mounted on the lathe body and connected to the X-axis servo motor. The tailstock and the intermediate seat are horizontally slidable in the X-axis direction on the lathe body, and the X-axis lead screw is threadedly connected to the tailstock. The tailstock center is located on the tailstock. The Y-axis lead screw is rotatably mounted above the intermediate seat and connected to the Y-axis servo motor. The four-tool holder is horizontally slidable in the Y-axis direction. The self-centering chuck and the tailstock are horizontally opposite each other. The rotary drive motor drives the self-centering chuck to rotate. The four-tool holder is located on the middle side between the self-centering chuck and the tailstock. The additive manufacturing heater and the additive manufacturing nozzle are located on the side of the four-tool holder. The additive manufacturing nozzle faces the center line of the self-centering chuck. The additive manufacturing heater is connected to the additive manufacturing nozzle. The extrusion tube is connected to the additive manufacturing heater and the additive manufacturing raw material extrusion module. The controller controls the X-axis servo motor, the Y-axis servo motor, the rotary drive motor, the additive manufacturing raw material extrusion module, and the additive manufacturing heater.

[0006] Optionally, the X-direction lead screw is connected to an X-direction handwheel, and the Y-direction lead screw is connected to a Y-direction handwheel.

[0008] Optionally, the self-centering chuck is connected to a first drive wheel, the rotation drive motor is connected to a second drive wheel, and a transmission belt is sleeved between the first drive wheel and the second drive wheel for rotation.

[0009] This additive manufacturing miniature lathe integrates an additive manufacturing module into the lathe body, achieving dual functionality of additive manufacturing and subtractive machining in a single device. This effectively overcomes the limitations of traditional single-processing methods and can meet the diverse machining needs of complex and precision parts. Workpieces do not need to be transferred between different machines, reducing machining steps and time costs. It also avoids errors caused by multiple clamping and positioning, significantly improving the machining accuracy and quality of parts. Furthermore, the integrated design of the equipment reduces the space occupied in production, optimizes the production layout, helps improve production efficiency, and lowers overall production costs, demonstrating high practical value and promising market prospects.
