Description

Split formula direction cutter structure

[ technical field ] A method for producing a semiconductor device

The utility model mainly relates to a split formula direction cutter structure.

[ background of the invention ]

During punching, a punching hole position needs to be fixed, and drilling is started after the position is determined; however, when the metal block is drilled, the drill bit is easy to slip on the smooth metal surface, so that the drilling accuracy is influenced, the hole position is not attractive in light, and the hole position is ineffective in heavy.

[ Utility model ] content

Punch for convenient location, improve the degree of accuracy of punching, the utility model provides a new structural scheme, this split formula direction cutter structure adopts following technical scheme:

a split type guide cutter structure comprises a cutter body, wherein the top end of the cutter body is provided with a plurality of cutting edge parts, the joint of the cutting edge parts is provided with a plane, the plane is provided with a concave position, and the concave position is provided with a detachable conical head;

the two sides of the concave position are respectively provided with an inserting groove, a clamping block extends out of the side surface of the conical head, and the conical head is connected with the clamping block in a matched mode through the inserting grooves to be fixed on the concave position.

Preferably, the cutting edge portion is helical.

Preferably, the height ratio of the cutting edge part to the conical head is 10: 1.

Preferably, an arc surface is arranged between adjacent cutting edge parts, and the junction of the arc surface and the cutting edge part is in smooth transition.

Preferably, the outer end face of the bottom of the cutting edge part is flush with the outer end face of the cutter body. The utility model discloses compare produced beneficial effect with the background art:

the above technical scheme is adopted in the utility model, adopted conical head and cutter body split structure, utilized the conical head location position of punching, utilize cutting edge portion to punch, avoided the condition of skidding to appear, the hole site is more standard. It has the advantages of simple structure, compact matching, reasonable design and the like; therefore, the product has excellent technical and economic performance.

[ detailed description ] embodiments

Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout.

In the present invention, unless otherwise expressly specified or limited, the terms "assembled", "connected", and "connected", if any, are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally connected; or may be a mechanical connection; the two elements can be directly connected or connected through an intermediate medium, and the two elements can be communicated with each other. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to specific situations.

The technical solution and the advantages of the present invention will be more clear and clear by further describing the embodiments of the present invention with reference to the drawings of the specification. The embodiments described below are exemplary and are intended to be illustrative of the present invention, but should not be construed as limiting the invention.

The utility model provides a preferred embodiment: as shown in fig. 1 and 2, a detachable guide cutter structure includes a cutter body 10, wherein a plurality of cutting edge portions 20 are disposed at a top end of the cutter body 10, and the cutting edge portions 20 are spiral. The joint of the cutting edge part 20 is provided with a plane 21, the plane 21 is provided with a concave position 22, and the concave position 22 is provided with a detachable conical head 30; the height ratio of the cutting edge part 20 to the conical head 30 is 10:1, the influence of the conical head on the hole position is reduced, and after the preset depth is reached, the conical head can be detached to continue drilling.

Inserting grooves 23 are respectively formed in two sides of the concave position 22, a clamping block 24 extends out of the side face of the conical head 30, the clamping block is connected with a spring, and the clamping block is controlled to bounce relative to the side face of the conical head through the spring; the conical head 30 is matched and connected with the clamping block 24 through the insertion groove 23 to be fixed in the concave position 22. An arc surface 25 is arranged between adjacent cutting edge parts 20, and the junction 26 of the arc surface 25 and the cutting edge part 20 is in smooth transition; the bottom outer end face 27 of the cutting edge part is flush with the outer end face 28 of the cutter body.

This cutter can use at electric hand drill, when driling to the metal block, glossy metal surface causes the drill bit to skid easily, and consequently this structure has adopted conical head and cutter body split structure, utilizes the conical head location position of punching, is utilizing cutting edge portion to punch, and the condition of having avoided skidding appears, and the hole site is more standard.

In the description of the specification, reference to the description of "one embodiment," "preferably," "an example," "a specific example" or "some examples" or the like means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the invention, and schematic representations of the terms in this specification do not necessarily refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

With the above structure and principle in mind, those skilled in the art should understand that the present invention is not limited to the above embodiments, and all modifications and substitutions based on the present invention and adopting the known technology in the art are within the scope of the present invention, which should be limited by the claims.
