Technical Field

[0001] The utility model relates to the technical field of cutting tools, in particular to a metal cutting roughing and finishing tool. Background Art

[0002] Cutting tools are tools used for cutting in mechanical manufacturing, also known as cutting tools. The vast majority of cutting tools are machine-made, but there are also hand-made ones. Since the cutting tools used in mechanical manufacturing are basically used to cut metal materials, the term "cutting tools" is generally understood to refer to metal cutting tools. Cutting tools used to cut wood are called woodworking tools. There is also a special type of cutting tool used for geological exploration, well drilling, and mine drilling, called mining tools, while most ordinary cutting tools can be used for metal cutting;

[0003] However, the existing roughing and finishing cutting tools are inconvenient to install during use, which results in a lot of time required to replace the tools after they are worn, resulting in reduced work efficiency. Utility Model Content

[0004] In view of the above problems existing in the existing metal cutting roughing and finishing tools, the present utility model is proposed.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A metal cutting roughing and finishing tool comprises a cutter head and a cutter bar, the front end of the cutter bar is fixedly connected to a connecting frame, the end of the connecting frame away from the cutter bar is fixedly connected to a connecting shell, the rear end of the cutter head is fixedly connected to a mounting block, the mounting block and the connecting shell are fixed by clamping, and a plurality of limiting plugs are symmetrically fixedly connected to the rear side of the mounting block, a plurality of through holes for the limiting plugs to extend through the side wall of the connecting shell are provided, an external thread is provided on the outside of the column wall at one end of the limiting plug, and a locking nut is threadedly connected, one side of the locking nut abuts against the outer wall of the connecting shell, and a plurality of retaining mechanisms for fixing the locking nuts are also provided on the outer wall of the connecting shell.

[0007] Preferably, the blocking mechanism includes a positioning seat fixedly connected to the outer wall of the connecting shell, the side wall of the positioning seat is provided with a socket, and a push-pull rod is movably inserted in the corresponding socket, one end of the push-pull rod is fixedly connected to a U-shaped anti-slip plate clamped outside the locking nut, a plurality of reset springs sleeved outside the push-pull rod are fixedly connected to the side wall on the opposite side of the U-shaped anti-slip plate and the positioning seat, and the rear end of the push-pull rod is fixedly connected to the push-pull plate.

[0008] Preferably, a plurality of card-connecting plates are symmetrically and fixedly connected to the outer wall of the mounting block, and a plurality of card-connecting slots matching and card-connecting with the card-connecting plates are provided on the inner side of the connecting shell.

[0009] Preferably, the connection between the knife rod and the connecting frame is symmetrically fixedly connected with a plurality of triangular reinforcing ribs.

[0010] Preferably, the outer surface of the card-connecting board is covered with a layer of damping rubber pad.

[0011] Preferably, the locking nut is a hexagonal nut structure.

[0012] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0013] The U-shaped anti-slip plate is pushed back by the reset spring, so that the U-shaped anti-slip plate clamp is outside the locking nut, and the locking nut is effectively limited, so as to prevent the vibration of the cutter head during processing from affecting the installation stability of the locking nut.
