Abstract

The utility model relates to a pore opener for compound materials, which is formed by the combination of a milling cutter body, a handle connecting body and a drill bit, wherein, the cutting end of the milling cutter body is the opening end and is provided with an inner cavity; a plurality of cutting edges are equidistantly arranged along the circumferential direction of the opening end, and the circumferential wall of the cutting edges is provided with a plurality of axial chip removal long groove pores which are communicated with the inner cavity and chip removal through pores on the cutting relative ends; one end of the handle connecting body is screwed at the cutting relative ends of the milling cutter body, and the other end of the handle connecting body provided with a drilling tool; the drill bit is inserted and tightly positioned at an inner pore of the center of the handle connecting body. The pore opener can drill once on objects forming the compound material structure, such as theft protection doors, and has the advantages of high efficiency and precision and convenient use.

Description

Pore opener for compound material

The utility model relates to a kind of drilling tool, particularly a kind of composite that is applicable to, for example drilling tool on iron, the wooden combining structure material.

At present, to the antitheft door processing lockhole of hophornbeam combining structure, generally be iron sheet to be punched with a kind of traditional hole making drill, with firmer chisel the timber of intermediate course is cut out again, and then use this hole making drill that the bottom iron sheet is punched; The perforate ability of this traditional hole making drill is only limited to opens the iron plate of wearing 5 millimeter, and powerless to the darker hole of processing, and also can't cut timber; Therefore, dig the safe lockhole of antitheft door like this in the mode of secondary operations, when not only taking a lot of work, and crudy is also bad.

The purpose of this utility model provides a kind of hole making drill that is suitable for once processing the hole of guaranteeing precision on composite, and this hole making drill can be suitable for being installed in easily on various drilling apparatus such as electric hand drill or the bench drill and cuts required lockhole with the composite to iron wood structure etc.

Composite hole making drill of the present utility model comprises: one has the end mill body of multi-tool edge, be characterized in, the described sword body that mills is that to contain an inner chamber and its cutting end be the hollow cylinder of openend, its other end is provided with a center screw, a plurality of cutting edges are located on the openend perisporium along circumferentially inlaying equally spacedly, at least also are provided with a chip removal elongated slot that axially extended and described inner chamber connects in the perisporium upper edge between its two ends and at least one chip-removal hole on the cutting edge opposite end; What comprise also that an one end is bolted in the end mill body center screw connects the handle body, a slotted hole along its central axis is arranged on it, and one can be inserted in the drill bit that connects in the handle body slotted hole; Described drill bit tightening is in connecing the handle body, and its cutting blade stretches out; Each plane, place, cutting edge outer end of described end mill body.

The cutting blade of described end mill body is a kind of carbide chip; Described drill bit can be a kind of spiral bit; It is locked in the lock-screw of radially screw spiral shell on connecing handle body wall knot by one and connects in the handle body endoporus.

This hole making drill is owing to adopt drill bit and milling cutter combination cutting way; It can construct unimpededly chip removal by the end mill body chip removal, therefore can be particularly suitable for the darker hole of processing on composite such as hophornbeam combining structure material to a perforate of composite; End mill body adopts carbide chip, and its cutting edge is sharp, wear-resisting, and applicable multiple metal material is for example to the perforate of stainless steel strip of paper used for sealing; The hole making drill of this structure not only can once carry out perforate expeditiously, and can guarantee positional precision and dimensional accuracy.

Now by an embodiment of the present utility model and description of drawings the purpose of this utility model, characteristics and advantage.

Fig. 1 is an embodiment assembly figure of hole making drill of the present utility model;

Fig. 2 is the part drawing of the end mill body cutter hub of Fig. 1 embodiment;

Fig. 3 is the right view of Fig. 2.

Referring now to accompanying drawing.As shown in the figure, hole making drill of the present utility model comprises: an end mill body 1, it is one to have the hollow cylinder of an inner chamber 5 and an openend, establish (as using welding method) some carbide chips 6 circumferentially equidistantly inlaying of open end, one center screw 7 and two chip removal through holes 8 are set on the end wall of its other end, on its perisporium, be provided with 3 axial microscler logical bits grooves 9 in uniform way, connect with inner chamber 5 respectively; One connects handle body 3, one end 10 spiral shells are tied in screw 7, the other end 11 is arranged to join the configuration that stick of tool is cut the chuck (not shown) of apparatus (as electric hand drill or bench drill), be provided with a slotted hole 12 along its central axis, be provided with a radially screw that connects with boring on its perisporium, a cylinder end clamping fixed screw 4 spiral shells are tied in this screw; One fried dough twist type drill bit 2 is inserted in the described boring 12, and by described holding screw 4 tightenings, the axial location of this drill bit is so that the drill bit blade exceeds the plane at place, all blades outer end.

Be the structure of a specific embodiment of the present utility model above, its partial structurtes can suitably change, as adopt the chip area and the hole of different numbers, also can set as required different numbers and structure blade and and different types drill bit etc. all be fine.

In use, for example perforate on antitheft door, this hole making drill at first door need introduce by the drill bit blade on the punch position, the end mill body cutting blade cuts off ground floor iron plate subsequently, behind the cut circular iron sheet to be removed, continue again the timber perforate, until bottom iron plate is cut into the hole, iron filings that produce in the working angles or wood chip can be discharged from chip area and hole, to avoid it to stop up hole wall and to stop further drilling, the wood waste of the centre after the processing becomes cylindrical simultaneously, can take out smoothly from cutting edge; Also can the perforate degree of depth as required set different end mill bodies and drill bit during use, the general degree of depth can reach about 60 millimeters.

Claims

1, a kind of hole making drill of composite, it comprises: one has the end mill body of multi-tool edge, it is characterized in that, described end mill body is that to contain an inner chamber and its cutting end be the hollow cylinder of openend, its other end is provided with a center screw, a plurality of cutting edges are located on the openend perisporium along circumferentially inlaying equally spacedly, at least also are provided with a chip removal elongated slot that axially extended and described inner chamber connects in the perisporium upper edge between its two ends and at least one chip-removal hole on the cutting edge opposite end; Also comprise an one end be bolted in end mill body center screw connect the handle body, a slotted hole along its central axis is arranged on it, and one can be inserted in the drill bit that connects in this slotted hole of handle; Described drill bit tightening is in connecing the handle body time, and its cutting blade stretches out the plane at each place, cutting edge outer end of described end mill body.
