Description

Technical Field

[0001] The utility model belongs to the technical field of machine tool processing equipment, and particularly relates to an adjustable small hydraulic support. Background Art

[0002] During machine tool processing, when loading materials, it is necessary to align the raw materials with the chuck of the machine tool. For the loading of long, heavy, and large materials, there is a lack of corresponding auxiliary tools, resulting in difficulties in centering the raw materials.

[0003] In the current field of machine tool processing, with the rapid development of the manufacturing industry, the requirements for processing accuracy and production efficiency are increasing day by day. However, in the actual processing process, especially when loading long, heavy, and large raw materials, there is a significant technical problem - difficulty in centering the raw materials.
