Description of the embodiments
The technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments of the present utility model, and do not limit the scope of the present utility model.
In the description of the present utility model, it should be noted that the directions or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.
In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.
Specific examples are as follows:
Embodiment 1 as shown in fig. 1-3, an automatically rotatable blade milling cutter head comprises a cutter disc 1, a cutter 2 and an externally threaded cylindrical pin 3. The cutter disc 1 is provided with cutter mounting grooves 101 in the circumferential direction, and 6 to 10 cutter mounting grooves 101 are preferably provided on the cutter disc 1. In the present embodiment, 6 tool mounting grooves 101 are provided in the tool tray.
In this embodiment, the cutter adopts a cylindrical structure.
In this embodiment, the tool includes a base 2012 and a cutting portion 2011 connected to the base 2012. Base 2012 is made of hard metal, and cutting portion 2011 is made of diamond or cubic boron nitride.
The cutter 2 is provided with a circular through hole along its central axis, and the inner diameter of the end portion of the circular through hole near the cutting portion 2011 becomes large, and a bearing 202 is provided there. The bearing 202 is internally connected with the external thread cylindrical pin 3, the end part of the external thread cylindrical pin 3 with external thread extends out of the circular through hole and is connected in the cutter mounting groove 101, the detachable connection of the cutter 2 and the cutter disc 1 is realized, and the cutter 2 can rotate around the external thread cylindrical pin 3. At the end of the cutting portion 2011 of the tool 2 remote from the base 2012, a ring of cutting edges is provided around the outer periphery of the cutting portion 2011 for cutting a workpiece.
In the present embodiment, a gap exists between the tool 2 and the mounting surface 1011 of the tool mounting groove 101 to avoid frictional resistance of the tool 2 and the tool disk 1.
When the cutter disc with the automatically rotatable blades is used, the cutter disc 1 drives the cutter 2 to rotate to cut a workpiece, meanwhile, the cutter 2 automatically rotates around the external thread cylindrical pin 3, the annular cutting edge on the cutter 2 cuts the workpiece, and in the process, the cutter 2 automatically rotates to enable the annular cutting edge to perform cutting work on the whole line, so that the abrasion rate is slowed down and the service life is prolonged relative to the existing cutter disc with the automatically rotatable blades.
