Description

Technical Field

[0001] This invention relates to the field of precision machining technology, specifically to a precision machine tool that integrates turning and milling. Background Technology

[0002] In the processing of energetic special materials, due to the special nature of the materials themselves and the strict requirements of the processing environment, the processing equipment must be operated within a sealed glove box. However, the limited space of the glove box places new demands on the size and functionality of the processing equipment.

[0003] Currently, machine tools used for machining energetic special materials typically only perform a single machining function, such as rough milling, finish milling, or turning. For workpieces requiring multiple operations, operators must transfer the workpiece between different machines multiple times, which not only increases operational complexity but also significantly reduces machining efficiency. Furthermore, due to the limited space inside the glove box, traditional machine tools often cannot achieve multi-functional integration while meeting size requirements, leading to low machining efficiency and increased costs.

[0004] While some multi-functional composite machine tools exist in the current technology, these devices are typically large in size and cannot fit into the confined space required by a glove box. Furthermore, due to the high precision and stability requirements of processing energetic special materials, traditional composite machine tools also have shortcomings in terms of function switching and precision maintenance. Therefore, developing a machine tool that can achieve multi-functional integration within a limited space while meeting the demands of high-precision processing has become a pressing technical challenge in the field of energetic special material processing.

Vision imaging module 6 is provided on milling and turning machine Z-axis moving module 9, rough milling module 4 and finish milling module 5 respectively.

[0026] In this embodiment, the lathe spindle module 11 is mounted on the lathe X-axis moving platform 81 via a flange-type spindle seat.

[0027] In this embodiment, the Z-axis moving module 9 of the milling machine and the X-axis moving module 8 of the lathe are arranged perpendicularly to each other, and the two are installed on the machine bed 1 in a T-shaped layout.

[0028] Coaxial integrated design: Turning and milling functions share the Z-axis motion platform, achieving multi-functional integration within a limited space.

[0029] Modular quick switching: The turning tool post 10 and the milling machine vacuum chuck 3 can be detachably connected to the turning and milling machine Z-axis moving platform 91 of the turning and milling machine Z-axis moving module 9, realizing quick replacement of the turning tool post 10 and the milling machine vacuum chuck 3, with a switching time of less than 5 minutes.

[0030] Process co-optimization: The seamless connection between the fine milling module 5 and the rough milling module 4 reduces the number of workpiece clamping operations.

[0033] The undisclosed technical features in this embodiment are the same as those in Specific Embodiment 1.

[0034] Specific implementation method three: Combining Figure 1 and Figures 4 to 5 This embodiment describes a lathe X-axis moving module 8 and a milling machine Z-axis moving module 9, both of which include a servo motor 12, a coupling 13, a ball screw 14, and a pair of rolling guides 15. The rolling guides 15 are fixed to the upper end of the machine bed 1, and the ball screw 14 is arranged parallel between the pair of rolling guides 15. The output end of the servo motor 12 is connected to one end of the ball screw 14 through the coupling 13. The lathe X-axis moving platform 81 is rotatably connected to the ball screw 14 in the lathe X-axis moving module 8 and slidably connected to the rolling guides 15. The milling machine Z-axis moving platform 91 is rotatably connected to the ball screw 14 in the milling machine Z-axis moving module 9 and slidably connected to the rolling guides 15. The vision imaging module 6 in the milling machine Z-axis moving module 9 is mounted on the milling machine Z-axis moving platform 91.

[0035] The undisclosed technical features in this embodiment are the same as those in Specific Embodiment 1.

[0036] In this embodiment, the servo motor 12 drives the ball screw 14 to rotate through the coupling 13, thereby driving the X-axis movement of the lathe X-axis moving platform 81 and the Z-axis movement of the milling machine Z-axis moving platform 91.

[0037] During turning, the workpiece is adsorbed and fixed onto the lathe spindle module 11 by the lathe vacuum chuck 7 (vacuum degree -90kPa). A high-precision fine-tuning tool post 10 is installed on the turning-milling Z-axis moving platform 91. Through the linkage control of the lathe X-axis moving module 8 and the turning-milling Z-axis moving module 9, turning of complex contours can be achieved. The lathe spindle module 11 has a speed range of 50-4500rpm, and with the servo drive system, it can meet the processing requirements of different materials.

After the workpiece is fixed by the chuck, the Z-axis moving platform 91 precisely moves it to the front or rear end of the gantry 2 for machining. The gantry 2 adopts a dual-module design for finish milling and rough milling, which can work together: after rough milling is completed at the rear end of the gantry 2, the workpiece can be immediately moved to the front end of the gantry 2 for finish milling without secondary clamping, significantly shortening the machining cycle. The finish milling spindle uses a small electric spindle, while the rough milling spindle is equipped with a medium-sized spindle, respectively meeting the requirements of high precision and heavy cutting.

[0044] The turning and milling modes of the machine tool can be combined, that is, the workpiece can be initially machined by turning, and then the subsequent machining process can be completed by rough milling and finish milling. This mode can realize the machining of most workpieces and improve machining efficiency.

After tool setting is completed, rough milling of the workpiece is performed, and the vision imaging module 6 monitors the machining status throughout the process. After rough milling is completed, the Z-axis moving platform 91 of the milling machine moves the workpiece to the front end of the gantry 2, performs tool setting again through the vision imaging module 6 on the finish milling module 5, and then performs finish milling. The upper vision imaging module 6 continues to monitor in real time to ensure that the workpiece meets the final accuracy requirements.
