Belt-transmission angle attachment head

A belt-transmission angle attachment head, comprising:

• a housing;
• a power mechanism;
• a transmission mechanism;
• and a spindle, with the power mechanism and transmission mechanism arranged in the housing, wherein:
• the power mechanism includes a servo motor and a reducer, the servo motor is connected to the reducer, and an input shaft of the reducer is vertically arranged with respect to an output shaft of the reducer;
• the transmission mechanism includes a driving wheel, a transmission belt and a driven wheel, and the driving wheel is mounted on the output shaft of the reducer;
• the housing comprises a cavity, wherein the power mechanism and the transmission mechanism are disposed within the cavity,
• one side of an end of the housing is provided with a spindle mounting portion, the spindle mounting portion is offset from a central portion of the housing, and a spindle accommodating space where the spindle can be arranged is formed between a lower portion of the housing and the spindle mounting portion,
• the spindle is disposed within the spindle accommodation space,
• a side of the spindle is mounted on the housing via a rotating shaft, an end of the rotating shaft away from the spindle is mounted with the driven wheel, the spindle and the driven wheel are arranged on different sides of the spindle mounting portion, the driving wheel and the driven wheel are connected via the transmission belt, and the spindle and the power mechanism are located on the same side of the transmission mechanism, and
• the spindle is positioned such that a direction extended in the longitudinal direction of the output shaft of the servo motor and from the output shaft of the servo motor intersects the spindle, and the servo motor, the reducer, and the spindle are arranged approximately on a straight line.
