Description

Technical Field

[0001] The utility model relates to an automatic lifting door, in particular to an automatic lifting door for a machine tool. Background Art

[0002] In order to improve production efficiency and safety during the production process, equipment that can meet the requirements of automated production is needed. Through the automation of equipment, the need for manpower is reduced, and self-inspection and automated processing of equipment are realized.

[0003] With the rapid improvement of modern automation, the processing of machine tools also needs to be automated. Since the front of the machine tool needs to be programmed and controlled, it is more economical and convenient to use a side lift door and a forklift arm type automatic line loading and unloading method.

[0004] The safety and smoothness of the lifting door during the opening and closing process are extremely important. During the opening and closing process, it is necessary to move quickly to ensure that the opening and closing are in place and to prevent chips from accumulating between the lifting door and the machine tool protection structure. In addition, due to the limitation of the machine tool installation space, the compactness of the overall structure of the machine tool is also required, especially when the indoor height space is small, the overall height of the machine tool is required to be reduced. The lifting door is installed on the machine tool protection structure, and it is necessary to lift up and down to realize the door opening and closing functions. Therefore, the overall height of the lifting door is an important factor affecting the overall height of the machine tool. Existing lifting doors are often driven by low-cost cylinders, and the cylinder is installed in the center of the top of the machine tool protection structure. When the lifting door is in the open and closed state, the upper part of the cylinder extends from the top of the machine tool protection structure, which is relatively abrupt, and the overall height of the lifting door is relatively high, which cannot meet the installation requirements when the indoor height space is small.
