Description

Technical Field

[0001] This invention relates to the field of five-axis machining center technology, specifically a cradle-type five-axis machining center. Background Technology

[0002] Five-axis machining centers, as core equipment for machining high-precision and complex workpieces, are widely used in key fields such as aerospace, precision molds, and high-end equipment manufacturing. Their machining accuracy, operational stability, and ease of operation directly determine the quality and production efficiency of the final product. With the increasing demand for precision machining in the manufacturing industry, existing five-axis machining centers have gradually revealed many technical shortcomings in practical applications, making it difficult to meet the needs of efficient and precise machining. For example, the crossbeam of a multi-functional five-axis machining center disclosed in CN117681058A is supported by two independent side walls, resulting in a large footprint and low space utilization due to the large floor space occupied by the double-side-wall structure. The dispersed layout of the drive components for each axis leads to uneven distribution of machine tool rigidity, which easily causes vibration, especially during high-speed movement, affecting machining stability and accuracy. For example, the crossbeam drive of the five-axis machining center disclosed in CN120921126A uses a single-motor, single-screw structure, resulting in unbalanced power output, causing the crossbeam to easily deviate and vibrate during movement, leading to significant positioning accuracy deviations.

[0057] Example 4 differs from this example in that the technical solutions and working principles based on Example 1, Example 2, or Example 3 are as follows: The protective cover 2 is equipped with a garbage truck 25 on its side. Metal chips and waste generated during processing can fall directly into or be guided to the garbage truck 25 on the side of the protective cover, preventing waste from scattering around key components such as the machine tool body 1, guide rails, and lead screws, and keeping the equipment interior and working environment clean. The garbage truck can collect waste in a centralized manner and can be directly transported and processed as a whole in the future, simplifying the waste recycling process. It is especially suitable for efficient waste management in batch processing scenarios.

[0058] An air conditioner 26 is installed on the protective cover 2, and the air conditioner 26 is used to regulate the temperature inside the protective cover 2.
