Description

One-step forming cutter for milling flat pin of drill rod

Technical Field

The utility model relates to a mill flat round pin technical field, especially relate to the drill rod mills flat round pin one shot forming cutter.

Background

The traditional method for milling the flat pin adopts a bar-shaped cutter to radially mill, the milling is carried out once when 3-5 drill rod milling cutters are milled, the requirement on the skill level of an operator is high, and the radian requirement of the flat pin cannot be met after the cutters are milled for several times.

A cutter is designed according to the requirement of milling a flat pin of a drill rod.

SUMMERY OF THE UTILITY MODEL

To the circumstances, for overcoming prior art's defect, the utility model provides a drill rod mills flat pin one shot forming cutter, solves the tradition and mills that flat pin cutter wearing and tearing are fast, radially mill the problem that requires high to operative employee skill level.

The technical scheme includes that the drill rod milling flat pin one-step forming cutter comprises a cutter body, the cutter body is transversely fed when milling the flat pin and is formed in one step, the cutter body comprises a cutter handle and a cutter head, the cutter handle is of a spherical structure with one end being arc-shaped, one end, used for milling the flat pin, of the cutter handle is evenly provided with a plurality of cutter head fixing frames and each cutter head fixing frame is respectively provided with the cutter head, the cutter head fixing frames and the corresponding cutter heads are detachably and fixedly connected, the cutter heads are replaced after being damaged, cutter grinding is not needed, and the problem that the radian requirement of the flat pin cannot be guaranteed after the cutter is ground for several times is avoided.

Furthermore, the diameter and the radian of the arc-shaped head of the cutter handle respectively correspond to the length and the radian of the flat pin, so that the length and the radian of the milled flat pin can meet the expected requirements.

Furthermore, each cutter head uses a bolt to connect one end far away from the cutting edge with the cutter head fixing frame, so that the replacement is simple.

Furthermore, the knife handle is connected with a driving power and is driven by the driving power to rotate, and the rotating direction is consistent with the cutting direction of the knife edge.

The utility model has the technical effects that the ball-shaped milling cutter is designed, the size of the milling cutter is the same as the length of the flat pin, the milling cutter is transversely fed when milling the flat pin, the flat pin is formed in one step, an operator is not required to control the length of the flat pin, the operation is simple, and the requirement on the skill of the worker is reduced; the tool bit is removable, need not to whet a knife, and efficiency can improve more than 30%.

Drawings

Fig. 2 is a conventional milling flat pin cutter.

In the figure: 1. the tool comprises a tool handle, 2. tool bits, 3. tool bit fixing frames and 4. bolts.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicating the directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Furthermore, it should be noted that, in the description of the present invention, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

The first embodiment is as follows: by figure 1, the drill rod mills cotter one shot forming cutter, including the cutter body, the cutter body is transversely cut when milling the cotter, one shot forming, the cutter body includes handle of a knife 1 and tool bit 2, handle of a knife 1 is the spherical structure that is convex one end, and the one end that handle of a knife 1 is used for milling the cotter evenly sets up a plurality of tool bit mounts 3, each along the circumferencial direction tool bit mount 3 punishment do not sets up the tool bit, fixed connection can be dismantled with corresponding tool bit 2 to tool bit mount 3, changes after the tool bit damages, need not to whet a knife, can't guarantee the problem that cotter radian required after avoiding the cutter to polish several times.

Example two: on the basis of the first embodiment, the diameter and the radian of the arc-shaped head of the cutter handle 1 respectively correspond to the length and the radian of the flat pin, so that the length and the radian of the milling flat pin can meet the expected requirements.

In the above embodiment, the diameter of the arc-shaped head of the tool holder is 180mm, and the corresponding radian is 135 degrees.

In the above embodiment, each of the tool bits 2 is connected to the tool bit holder 3 at the end away from the cutting edge by using the bolt 4, so that the replacement is simple, the tool holder 1 is connected to the driving power and is driven by the driving power to rotate, and the rotating direction is consistent with the cutting direction of the cutting edge.

The present invention has been described in detail with reference to the specific embodiments and examples, but these should not be construed as limitations of the present invention. Numerous variations and modifications can be made by those skilled in the art without departing from the principles of the invention, which should also be considered as within the scope of the invention.
