[0002] With the advent of the Industrial 4.0 era, the degree of automation in production and manufacturing has become increasingly higher, and machining centers have been widely promoted. Among them, the gantry machining center, as a processing mother machine for efficient processing of large parts, has a very considerable market share. After the machine tool is equipped with a tool magazine option, the processing capacity and processing range are greatly increased, and it becomes a machining center. After the machine tool is equipped with a tool magazine, due to the relatively poor processing environment in the processing area, the tool magazine needs to be isolated from the machine tool processing range within the machine tool processing time range, and the isolation needs to be released within the tool change time range to realize the tool change action of the tool change mechanism. The tool magazine sliding door is a structure that isolates and connects the tool magazine with the machine tool processing range, and is widely used on gantry machine tools.

[0003] Traditional tool magazine sliding doors in the machine tool industry mostly use hydraulic or pneumatic as the power source, and oil cylinders or air cylinders as the actuators, which are not environmentally friendly and have relatively high energy consumption. In addition, since the speed and displacement of pneumatic or hydraulic tool magazine sliding doors cannot be accurately controlled, the two requirements of high speed and quietness cannot be achieved at the same time. With the development of the machine tool industry, more and more customers have put forward higher requirements on the environmental protection, efficiency, energy consumption and other aspects of machine tool tool magazine sliding doors, and the existing tool magazine sliding doors are difficult to meet customer requirements.
