Description

Technical Field

[0001] This utility model relates to the technical field of CNC lathes, and specifically to a lathe device with interpolation function. Background Technology

[0002] CNC lathes, as core equipment in modern manufacturing, are widely used in the precision machining of various rotating parts. Their machining efficiency, accuracy, and adaptability directly affect production quality and cost. Traditional lathes mostly adopt a single-spindle structure, which can only process a single workpiece or a single process at a time. For parts requiring multi-process machining, repeated clamping or batch processing of multiple workpieces is necessary, resulting in poor production continuity and difficulty in meeting the needs of mass production. To address these issues, twin-spindle lathes were invented. However, while twin-spindle lathes can process simultaneously, the coordination between the spindles is insufficient, making it impossible to achieve automatic workpiece transfer and secondary processing. Manual handling is still required, increasing working time and error risks, and affecting machining efficiency and quality. Furthermore, existing lathes lack error compensation functions during machining. When performing certain complex surface or high-precision compensation machining, they lack the ability to perform linear interpolation feed in specific angular directions, limiting further improvement in machining accuracy. The workpieces that have been turned need to undergo subsequent finishing machining to complete the final product, affecting the machining efficiency and quality of the workpiece.

[0013] Compared with the prior art, the above-mentioned technical solutions of the lathe equipment with interpolation function provided in the embodiments of this utility model have at least one of the following technical effects: 1. This utility model utilizes a dual-spindle machining system consisting of a first spindle device and a second spindle device. A first moving mechanism enables the reciprocating movement of the second spindle. Furthermore, independently controllable second and third moving mechanisms allow for the simultaneous parallel processing of two workpieces (such as batch processing with identical requirements or differentiated processing with different requirements). This increases processing efficiency by over 50%, improving production efficiency. The first moving mechanism allows the second spindle to move to the position of the first spindle to clamp the processed workpiece, enabling automatic transfer and secondary processing of the same workpiece within the machine (such as turning at both ends). This eliminates the need for manual transfer and repositioning, reducing clamping errors, ensuring part form and position tolerances (such as coaxiality ≤ 0.01mm), and reducing labor intensity.

[0014] 2. By setting up an interpolation mechanism to compensate for errors during workpiece machining, the tool magazine mechanism gains an additional feed degree of freedom in the tilt direction on top of its X and Z axis movements. This allows the tool to perform linear interpolation movements on the workpiece according to machining requirements, enabling real-time, online compensation for machining errors caused by tool wear or thermal deformation. This allows the lathe to perform precision machining of complex curved surfaces and irregular contours, controlling workpiece dimensional accuracy within ±0.005mm and reducing surface roughness Ra by 30%, significantly improving workpiece machining accuracy and surface quality.

The first platform 3 has a first moving mechanism 7, the second spindle assembly 6 being mounted on the first moving mechanism 7 and reciprocating toward the first spindle assembly 5. Both the first spindle assembly 5 and the second spindle assembly 6 have chucks 8 for material clamping, and both chucks 8 are located on the same central axis. The second platform 4 has two opposing second moving mechanisms 9, each of the second moving mechanisms 9 having a third moving mechanism 10 reciprocating toward the first platform 3, and each third moving mechanism 10 having an interpolation mechanism 1. 1. Each of the interpolation mechanisms 11 is equipped with a tool magazine mechanism 12. The surfaces of the first platform 3 and the second platform 4 are both inclined surfaces. The inclined surfaces facilitate turning and improve the flow of cutting fluid. Two second moving mechanisms 9 are set to control the movement of the two tool magazine mechanisms 12 respectively. With the first spindle device 5 and the second spindle device 6, multi-station turning is realized, which improves the processing efficiency.
