Abstract

The utility model discloses a diamond boring tool. A plurality of cutting knife heads are uniformly fixed on the lower end surface of a metal cylinder substrate; the upper end surface of the metal cylinder substrate is provided with a boss; the boss is provided with a threaded through hole; the circumference of the metal cylinder substrate is uniformly provided with four grooves; and two inclined hollowing through troughs are symmetrically arranged on the side wall of the metal cylinder substrate. Four grooves at the circumference of the metal cylinder substrate can play a function of enlarging the space during the core-taking process, thus taking the core successfully. The cutting knife heads contain the diamond compositions, thus being sharp and capable of drilling holes on hard materials, having stable boring process compared with normal boring bit, and greatly improving the control capability on the diameter of the bore and the quality of the bore wall. The boring tool has long service life. When the cutting knife heads fall down due to failure or are completely abraded due to long-term usage, the standby cutting knife heads can be welded on the metal cylinder substrate so as to be used continuously.

Description

A kind of diamond Hole drilling set

Technical field

The utility model relates to a kind of Hole drilling set.

Background technology

Run into the occasion that needs punching through regular meeting in daily life and the engineering; usually usefulness is electric perforator; the puncher front end is equipped with grooved bit; the front end of this class grooved bit normally is made up of carbide alloy; smashing the purpose of material to reach cutting, is the groove of screw type around the grooved bit drill bit, be used for bore chip discharge; also be welded with the alloy blade all around, to improve the punching effect.But the defective of this class grooved bit is: diameter is all less, and general diameter is commonly used to hit hole or aperture less than 60mm, and a lot of these class grooved bits of occasion can not use, or the punching effect is relatively poor.As factory floor heavy duty machine tools are installed, need to punch on the cement flooring below the lathe so that the fixed position of lathe is put into wherein, the general diameter in this hole is between 100～300mm, and the grooved bit commonly used moulding of can not once punching needs repeatedly punching and efficient very low.Sometimes need on armored concrete, punch, usually run into and get the core situation of difficult.

Summary of the invention

The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art, a kind of diamond Hole drilling set of getting the core convenience and can opening large diameter hole to be provided.

The technical solution adopted in the utility model is: several cutter tips evenly are fixed on the lower surface of metallic cylinder matrix, has a boss on the upper surface of metallic cylinder matrix, tapped through hole is set on the boss, uniform four grooves around the metallic cylinder matrix, two oblique hollow out grooves are symmetricly set on the sidewall of metallic cylinder matrix.

The beneficial effects of the utility model are:

1, four grooves around the metallic cylinder matrix can play the effect of expansion space when getting core, so that get core smoothly.The time run into reinforcing bar sometimes as boring on armored concrete and be stuck in situation in the drill bit, at this moment rotary drilling-head is easier to taking-up with the reinforcing bar partial rotation to the groove part ratio.

2, contain the diamond composition in the cutter tip, sharper, can on harder material, hole, boring procedure is more steady with respect to common drill bit, has greatly improved the control ability in aperture and the quality of hole wall.

3, the life-span of drilling tool longer, when cutter tip hinders for some reason and comes off or use when grind to the greatest extent because of long-term, standby cutter tip can be welded in continuation use on the metallic cylinder matrix.

4 if the brill macropore then only need be done the metallic cylinder matrix size of pore-forming, cutter tip quantity is improved just can.

5, the metallic cylinder matrix surface has two oblique hollow out grooves, can play the effect that reduces noise in boring procedure.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is a front view of the present utility model.

Fig. 2 is the cutaway view of Fig. 1.

Fig. 3 is the vertical view of Fig. 1.

Among the figure: 1. metallic cylinder matrix; 2. cutter tip; 3. oblique hollow out groove; 4. groove; 5. boss; 6. tapped through hole.

The specific embodiment

As Figure 1-3, several cutter tips 2 evenly are fixed on the lower surface of metallic cylinder matrix 1, and the diameter of metallic cylinder matrix 1 is 150-200mm,, height is 160-280mm.Cutter tip 2 mixes the back sintering by diamond particles and some metal dusts with special ratios and forms, be welded on after sintering on the lower surface of metallic cylinder matrix 1, the height of cutter tip 2 is 8-15mm, and thickness is identical with the barrel thickness of metallic cylinder matrix 1.The cross section of cutter tip 2 is circular-arc, and its circular arc outline overlaps with metallic cylinder matrix 1 outline.Two oblique hollow out grooves 3 are symmetricly set on the sidewall of metallic cylinder matrix 1, can reduce operating noise.Uniform four grooves 4 around the metallic cylinder matrix 1 increase the space, are convenient to get core.Has a boss 5 on the upper surface of metallic cylinder matrix 1, tapped through hole 6 is set on the boss 5, tapped through hole 6 is made up of a major thread through hole and some minor thread through holes on every side thereof, boss 5 with metallic cylinder matrix 1 upper end during use matches with electronic drilling machine by flange, link to each other with bolt, carry out operation perpendicular to boring object, the drilling depth maximum is 130-240mm.

Claims

1. diamond Hole drilling set, comprise metallic cylinder matrix (1), it is characterized in that: several cutter tips (2) evenly are fixed on the lower surface of metallic cylinder matrix (1), has a boss (5) on the upper surface of metallic cylinder matrix (1), screwed hole (6) is set on the boss (5), uniform four grooves (4) around the metallic cylinder matrix (1), two oblique hollow out grooves (3) are symmetricly set on the sidewall of metallic cylinder matrix (1).
