[0002] The machine tool loading trolley is an auxiliary equipment used in the machine tool processing process, mainly used for conveying, loading and unloading and moving raw materials, semi-finished products or finished products. It can save manpower when loading and unloading materials on the machine tool, improve production efficiency, reduce workpiece damage, and can better connect with the automated production line. The machine tool loading trolley has the characteristics of compact structure, small size and large carrying capacity. According to actual needs, the machine tool loading trolley can be fixed or adjustable in height; it can be tracked or trackless. When choosing a machine tool loading trolley, it is necessary to consider its compatibility with the machine tool, whether the carrying capacity meets the requirements, and whether it meets the safety standards of the workplace.

[0003] When the material warehouse trolley moves to the working area, the trolley travels on the track through rollers. Due to the instability of the roller rotating rod, the loading trolley is not stable enough when it stops, which often causes a large position deviation of the trolley, which is not conducive to the grasping of the workpiece by the machine tool fixture, resulting in reduced work efficiency. The trolley is usually used in various scenarios, including transporting flat plates and various cylindrical materials, such as steel pipes, steel bars, etc. When transporting such cylindrical materials, the materials need to be fixed, otherwise the materials will roll off, causing material damage and safety hazards.
