The utility model discloses a positioning assembly. The positioning assembly comprises an outer shell; the main shaft is rotationally arranged on the outer shell; the output gear is connected to the output end of the main shaft; the brake is arranged in the outer shell and used for limiting rotation of the main shaft; and the rotary encoder is connected to the input end of the main shaft and used for monitoring the rotary speed of the main shaft, and when the speed of the main shaft reaches a preset value, the brake brakes the main shaft so as to limit rotation of the main shaft and the output gear. By the adoption of the slewing mechanism, the positioning precision of the slewing mechanism is improved, the shaking amount caused in the braking process is reduced, and the safety and stability of equipment are enhanced. 本申请公开了一种定位组件，包括：外壳体；主轴，转动设置于所述外壳体上；输出齿轮，连接于所述主轴的输出端；制动器，设置于所述外壳体内，用于限制所述主轴转动；以及回转编码器，连接于所述主轴的输入端，用于监测所述主轴的回转速度，当所述主轴的速度达到预设值时，所述制动器制动所述主轴，以限制所述主轴和输出齿轮转动。通过采用本申请，提高了回转机构的定位精度，降低了制动过程中带来的晃动量，增强了设备
