Feeding table of screw locking system and screw locking system

The utility model provides a feeding table of a screw locking system and the screw locking system. The feeding table is provided with a supporting frame used for containing low-temperature parts and a preheating mechanism located on one side of the supporting frame. The supporting frame comprises two first supporting pieces arranged in the longitudinal direction in a spaced mode, the preheating mechanism is used for preheating the to-be-machined part of the low-temperature part to the room temperature, and the situation that when screws are locked, the temperature difference between the two parts needing to be connected through bolts is too large, and the torque is greatly reduced after the screws are locked is avoided. Therefore, connection failure caused by too small residual torque is avoided, and connection quality and connection efficiency are improved. 本实用新型提供一种锁螺丝系统的上料台及锁螺丝系统，所述上料台上设有用于放置低温零件的支撑架和位于支撑架一侧的预热机构；所述支撑架包括沿纵向方向间隔设置的两个第一支撑件，所述预热机构用于将低温零件待加工部位预热至室温，避免锁螺丝时，需要螺栓连接的两零件温差过大，导致锁螺丝工作完成后，扭矩大幅度衰减，使得残余
