The specific embodiment is as follows:

the utility model will be described in further detail with reference to the drawings and the detailed description.

In the description of the present utility model, it should be understood that the terms "longitudinal," "transverse," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present utility model, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present utility model.

As shown in fig. 1-2, the equally divided machining dividing head structure comprises a rotary shaft 1, one end of the rotary shaft is connected with a three-jaw chuck 2, the three-jaw chuck 2 is used for clamping a horizontally arranged workpiece 3 (the axis is in the transverse direction), the rotary shaft 1 is transversely arranged on a supporting seat 4, one end, far away from the three-jaw chuck 2, of the rotary shaft 1 is fixedly provided with a circular dividing head 5, when the dividing head is rotated, the dividing head 5 drives the three-jaw chuck 2 to synchronously rotate through the rotary shaft 1, a plurality of positioning jacks 6 are uniformly distributed on the outer circumferential surface of the dividing head 5, and the positioning jacks 6 extend along the radial direction of the dividing head 5; one end of the top of the supporting seat 4, which is far away from the three-jaw chuck 2, is provided with a positioning perforation 7 which is vertically communicated, a positioning bolt 8 is arranged in the positioning perforation 7 in a penetrating manner, the positioning bolt 8 is inserted into one of the positioning jacks 6, and the dividing head cannot rotate at the moment. During working, the cylindrical workpiece 3 is horizontally clamped on the three-jaw chuck 2, and the processing cutter 9 is positioned above the workpiece 3; after the outer circumferential surface of the workpiece 3 is machined once by the machining tool 9, the positioning plug pins 8 are manually pulled out, then the dividing head 5 is rotated to enable different positioning insertion holes 6 to be opposite to the positions of the positioning through holes 7, then the positioning plug pins 8 are manually inserted into the positioning insertion holes 6 corresponding to the positions after passing through the positioning through holes 7, the dividing head 5 cannot rotate by using the positioning plug pins 8, and at the moment, the outer circumferential surface of the workpiece 3 can be machined next time by the machining tool 9.
