Description

Technical Field

[0001] This utility model relates to the field of machining centers, and in particular to a dual-spindle multi-station machining center. Background Technology

[0002] With the trend of modern manufacturing towards high efficiency, precision, and integration, parts processing places increasingly stringent demands on equipment processing efficiency, process coverage, and processing accuracy. Multi-station machining centers, as core equipment for realizing integrated processing of complex parts, directly determine production cycle time and product quality, and are widely used in high-end manufacturing fields such as automotive parts, aerospace components, and precision molds.

[0003] Currently, most mainstream multi-station machining equipment on the market uses a single-spindle structure. When machining parts with multiple processing requirements (such as box-shaped or disc-shaped parts), this type of equipment requires multiple clamping, tool changes, or station switching to complete different surfaces or different types of machining processes. This machining mode has significant drawbacks: on the one hand, multiple clamping inevitably introduces repetitive positioning errors, making it difficult to guarantee the positional accuracy of each machined surface of the part. Especially for precision parts with high precision requirements, clamping errors often become a key bottleneck restricting machining quality. On the other hand, the clamping, tool changing, and station switching processes consume a large amount of non-cutting time, significantly reducing the effective cutting efficiency of the equipment and failing to meet the demand for shorter cycle times in mass production.

[0004] To improve the efficiency of single-spindle equipment, some manufacturers have introduced machining equipment with auxiliary spindles. However, the auxiliary spindles of such equipment mostly only have positioning or simple clamping functions and cannot achieve collaborative machining with the main spindle. In essence, they are still an extension of the single-spindle machining logic and fail to fundamentally solve the contradiction between efficiency and accuracy in multi-process machining.

[0005] Therefore, in order to address the shortcomings of existing processing equipment in multi-process precision machining, such as low efficiency, poor positioning accuracy, and weak adaptability, it is urgent to develop a machining center that can realize dual-spindle collaborative operation, multi-station integrated machining, and has high-precision three-axis linkage control capabilities to meet the development needs of modern manufacturing industry.
