The invention relates to the field of machining, in particular to a multi-head non-continuous spiral groove trolley. A workbench is included and provided with a sliding groove and a through groove. The through groove is provided with a first threaded rod. The first threaded rod is provided with a sliding block. The sliding block is provided with a cylinder. The cylinder is provided with bristles.The sliding block is provided with a cone. The workbench is provided with a first servo motor. The first servo motor is provided with a first casing pipe. The first casing pipe is provided with a first hexagonal inserting rod connected with a machined piece. The sliding groove is provided with a second threaded rod, the second threaded rod is connected with a second servo motor, and the second threaded rod is provided with a slide block provided with a U-shaped plate. The U-shaped plate is provided with a third threaded rod, the third threaded rod is connected with a third servo motor, the third threaded rod is provided with an installing base, the installing base is provided with a second casing pipe, and the second casing pipe is provided with a second hexagonal inserting rod. Accordingto the multi-head non-continuous spiral groove trolley, the tool position is conveniently adjusted and can be conveniently adjusted to be suitable for different slotting depths, and meanwhile the multi-head non-continuous spiral groove trolley adapts to shaft sleeve type components different in diameter for forming multi-head non-continuous spiral grooves.
