Description

Technical Field

[0001] This invention relates to the field of CNC machine tool technology, and in particular to a multi-station machining machine tool for mass production. Background Technology

[0002] Machine tools typically refer to mechanical equipment used for processing metal parts. During the processing, the workpiece is clamped and fixed by the spindle box to make it rotate at high speed, and then cutting is achieved by the high-speed rotating workpiece contacting the cutting head.

[0003] With the development of aerospace, automobile, mold, electronic products and medical devices, the product forms are becoming more diversified and complex, and the surface quality requirements are also getting higher and higher. This puts forward higher requirements for the processing capabilities of CNC machine tools. They are required not only to be able to process complex surfaces, but also to ensure high speed, high efficiency and high precision in the processing process. Generally, five-axis linkage machine tools are used for processing.

[0004] Traditional five-axis linkage machine tools have the following defects: (1) They are expensive, difficult to maintain, and have a large size; (2) Generally, a machine tool is equipped with a five-axis rotary table to process parts. Therefore, a five-axis linkage machine tool can only process a single product. After processing, the product needs to be manually removed from the five-axis rotary table. Then, the processed single product is moved to the next station for processing. A new single product is then installed on the five-axis rotary table for processing again. This single-station processing is inefficient when users are producing a large number of products; (3) In traditional five-axis rotary tables, products are usually clamped by hydraulic chucks. However, the opening of the jaws and the clamping force of the hydraulic chuck are fixed and suitable for use with fixed products. When our products have many specifications, different sizes, and different clamping force requirements, we also need to replace the hydraulic chucks of different specifications. The compatibility is poor. In addition, when the traditional hydraulic chuck is ensuring centering and clamping, it cannot make the product quickly move to the center of the hydraulic chuck.
