Abstract

An integrated multipurpose cutter comprises a cutter handle, a drill bit and a circular cutter rest, wherein the drill bit and the cutter handle are arranged concentrically, the circular cutter rest is arranged concentrically with the cutter handle, the circular cutter rest is provided with an inner hollow circle, at least two blades which are arranged concentrically with the cutter handle are embedded on the bottom surface of the circular cutter rest, the inner end of each blade extends into the inner hollow circle by a first preset length, and the outer end of each blade protrudes out of the outer circle of the circular cutter rest by a second preset length; and a discharge port communicated with the inner hollow circle is arranged on the circumference of the circular knife rest. The utility model has the advantages of can once only process out foraminiferous work piece in cylinder center or the foraminiferous work in cylinder center.

Description

Integrated multipurpose cutter

Technical Field

The utility model relates to a be suitable for multi-purpose cutter of integral type that CNC board used.

Background

In the prior art, if a workpiece with a hole in the center of a cylinder is to be processed or the center of the cylinder is provided with the hole, a circular groove is arranged around the cylinder. The drilling, milling of the inner circle and milling of the outer circle and the like are generally finished in multiple steps. Not only is labor and time consuming, but also the processing precision is difficult to guarantee.

SUMMERY OF THE UTILITY MODEL

In order to overcome the problems, the utility model provides an integrated multipurpose cutter which can process a workpiece with a hole in the center of a cylinder or a workpiece with a hole in the center of a cylinder at one time.

The technical scheme of the utility model is that: the integrated multipurpose cutter comprises a cutter handle, a drill bit and a circular cutter rest, wherein the drill bit is arranged concentrically with the cutter handle, the circular cutter rest is provided with an inner hollow circle, at least two blades are embedded on the bottom surface of the circular cutter rest and are arranged concentrically with the cutter handle, the inner end of each blade extends into the inner hollow circle by a first preset length, and the outer end of each blade protrudes out of the outer circle of the circular cutter rest by a second preset length; and a discharge port communicated with the inner hollow circle is arranged on the circumference of the circular knife rest.

As an improvement to the present invention, the blade is reinforced by fasteners.

As an improvement of the utility model, the blade is made of tungsten steel material.

As an improvement to the utility model, the circular knife rest is made of alloy materials.

The utility model has the advantages of can once only process out foraminiferous work piece in cylinder center or the foraminiferous work in cylinder center.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 to 3, fig. 1 to 3 disclose an integrated multipurpose cutting tool, which includes a tool holder 1, a drill 2 concentrically disposed with the tool holder 1, and a circular tool holder 4 concentrically disposed with the tool holder 1, wherein the circular tool holder 4 is provided with a hollow circle 41, at least two blades 43 concentrically disposed with the tool holder 1 are embedded on a bottom surface 42 of the circular tool holder 4, an inner end 431 of each blade 43 extends into the hollow circle 41 by a first predetermined length, and an outer end 432 of each blade 43 protrudes out of an outer circle 433 of the circular tool holder 4 by a second predetermined length; the circumference of the circular knife rest 4 is provided with a discharge opening 45 communicated with the inner hollow circle 41.

Preferably, the blade 43 is reinforced by a fastener 44 to the blade 43.

Preferably, the blade 43 is made of tungsten steel.

Preferably, the circular tool holder 4 is made of an alloy material.

Referring to fig. 4, the following description will be made with reference to fig. 4.

Assuming that the workpiece 3 shown in fig. 4 is to be machined, it can be seen that the workpiece 3 has a center post 31, a hole 32 is provided in the center of the center post 31, the outer circle of the center post 31 is milled, the inner wall of the annular groove 33 of the workpiece 3 is milled, and in general, multiple steps of drilling, milling the outer circle of the center post, milling the inner circle of the annular groove, and the like are required for machining each surface of such a workpiece. However, use the utility model discloses the cutter can once only process and accomplish, during the use, with handle of a knife 1 and CNC board fixed connection, it is rotatory to drive by the CNC board, exert external force with work piece 3 to the translation of cutter direction, because the cutter is rotatory, drill bit 2 can process the hole 32, the inner 431 of blade 43 can mill the processing to the excircle of center post 31, and the outer end 432 of blade 43 can mill the processing to the inner wall of ring channel 33, three step is once only accomplished, save time and labor, reduce the processing cost, improve machining efficiency.

All equivalent changes made by the contents of the specification and the drawings of the utility model are equally covered by the scope of the claims of the utility model without departing from the idea of the utility model.
