Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of machining manufacturing, specifically, relate to a workpiece processing machine tool fixed clamping device. BACKGROUND

[0002] With the sustained growth of the global economy, manufacturing as the pillar industry of the national economy, is developing vigorously, its quality pace of improvement is also accelerating. In the core field of machining manufacturing, the processing of workpiece is endowed with unprecedented importance, this not only reflects in the strict requirements on product performance and precision, also reflects in the fine control of processing environment. To ensure that the workpiece can reach the design requirements of quality standards, the processing process often needs to be carried out under specific environmental conditions, such as constant temperature, constant humidity, dust-free, etc., to minimize the influence of external factors on the machining precision.

[0003] Facing the increasingly complex structure, shape variable workpiece, the traditional processing method has been difficult to meet the demand of high efficiency, high precision. Therefore, using specific, highly specialized processing tools becomes an inevitable trend. These tools not only require high rigidity and precision, but also need to adapt to the narrow and limited processing space, which puts high requirements on the skill level of operators and the flexibility of equipment. Especially key is, under such limited conditions, how to ensure the stability of the workpiece in the processing process has become a problem to be solved. If the workpiece cannot be effectively and reliably fixed, even a small swing may lead to the accumulation of processing errors, and thus seriously reduce the processing quality, and even cause safety accidents. In addition, the vibration of the machine tool during operation is another major factor affecting the machining precision. It not only interferes with the machining precision of the workpiece, but also may cause irreversible damage to the structure of the workpiece under long-term action, especially in the field of high-end precision manufacturing, such as high-end aviation manufacturing, this influence is particularly significant.

[0004] In high-end aviation manufacturing, workpieces often bear extremely critical functions, and their machining precision requirements are almost stringent. Although the traditional fixed clamping device can realize the fixation of the workpiece to a certain extent, it usually adopts a one-time fixation method, lacks flexibility, and cannot be adjusted according to the actual situation in the processing process. The limitation of this fixation method is that once the position or shape of the workpiece changes slightly, the fixed clamping device is difficult to adapt, resulting in poor fixation effect. The position of the fixed clamping device is often limited by the layout of the workpiece, which undoubtedly increases the processing difficulty and cost, and limits the improvement of processing efficiency. Therefore, the development of a new type of fixed clamping device that can adapt to different workpiece shapes, sizes and processing environments, and has adjustable and feedback functions, has become a technical problem to be solved in the field of mechanical machining manufacturing, and is also the key to promoting the development of manufacturing industry to higher quality and higher efficiency.
