Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of profile milling, in particular to a profile machining milling equipment. BACKGROUND

[0002] In the field of profile machining, milling is a common machining process, widely used in construction, machinery manufacturing, rail transportation and other industries. Profiles usually have a large length size, such as several meters or even tens of meters, which makes it difficult to position, prone to deformation, and difficult to ensure machining accuracy during processing. Traditional profile machining equipment usually uses a fixed workbench or a short-stroke clamping mechanism, which is difficult to adapt to the continuous processing needs of long-size profiles, often requiring multiple clamping or manual position adjustment, which not only reduces efficiency, but also affects processing quality due to repeated positioning errors. In the prior art, some milling equipment has multi-axis linkage function, but its clamping mechanism is usually designed only for short profiles, and cannot stably support and transport long profiles. In addition, the tool switching mechanism of traditional equipment relies on manual operation or simple tool changer, and frequent switching of tools during processing of long profiles will significantly reduce production efficiency. At the same time, long profiles are prone to deflection and deformation due to their own weight or cutting force during processing, and the support and clamping mechanism of traditional equipment often lacks self-adaptive adjustment capability, resulting in reduced machining accuracy. Therefore, it is urgent to develop a milling equipment specially used for long profile machining, which can realize stable clamping, automatic conveying and efficient switching of multiple processes to meet the high-precision, continuous processing needs of long-size profiles.
