Technical Field

The invention relates to the technical field of drill bits, in particular to a drill rod convenient to replace and install.

Background

The drill is a tool for drilling through holes or blind holes in solid materials and reaming existing holes. Commonly used drill bits mainly include twist drills, flat drills, center drills, deep hole drills, and trepanning drills.

The current drill bit is of an integrated structure, and the required drilling through specifications and sizes are different according to different processing requirements, so that the manufacturing cost is obviously higher according to different requirements.

Disclosure of Invention

Aiming at the defects and shortcomings of the prior art, the invention provides the drill rod which is convenient to replace and install, the drill bits with different sizes are convenient to replace, the matching performance is stronger, the working efficiency is effectively improved, and the manufacturing cost is reduced.

In order to achieve the purpose, the invention adopts the following technical scheme: it comprises a double-edge cutter bar and a cutter handle; one end of the knife handle is integrally formed with a double-edge knife bar; the other end of the double-edge cutter bar is integrally formed with an adapter part; it also includes:

the drill bit is detachably connected to the end part of the adapter part by a screw; and the joint of the drill bit and the switching part is arranged in a clearance way.

Preferably, the adapter part and the side wall of the drill are provided with mutually-through type drain holes.

Preferably, the joint of the drill bit and the adapter part is matched with a sawtooth meshing structure.

The working principle of the invention is as follows: the drill bit is fixedly connected with the adapter part of the double-edge cutter bar by screws, and the drain holes formed in the side wall are communicated into a whole for draining water; because the drill bit and the switching part are arranged in a clearance way, the switching part can be conveniently provided with the drill bits with different specifications, and the processing diameter and efficiency are improved; the arrangement of the double-edge cutter bar is more convenient for tapping and chip removal.

Compared with the prior art, the invention has the beneficial effects that:

1. the arrangement of the drain hole is adopted, so that the drainage and chip removal in the drilling process are facilitated;

2. the drill bit and the double-edge cutter bar are detachably connected by using the screw, so that the drill bit is convenient to replace;

3. adopt to keep away the empty setting, the twolip cutter arbor of being convenient for matches the drill bit of different specifications, and the suitability is wider, improves processing doubly footpath and efficiency.

Description of reference numerals:

the double-edge cutter rod comprises a double-edge cutter rod 1, an adapter part 1-1, a cutter handle 2, a drill 3, a screw hole 3-1, a water drainage hole 4 and a gap 5.

Detailed Description

The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings, and the preferred embodiments in the description are only examples, and all other embodiments obtained by those skilled in the art without any inventive work belong to the protection scope of the present invention.

As shown in fig. 1 and fig. 2, the following technical solutions are adopted in the present embodiment: the double-edge tool comprises a double-edge tool bar 1 and a tool handle 2; one end of the knife handle 2 is integrally formed with a double-edge knife bar 1; the other end of the double-edge cutter bar 1 is integrally formed with an adapter part 1-1; it also includes:

the drill bit 3, the drill bit 3 and the adapter part 1-1 are both provided with a screw hole 3-1 which is communicated with each other, and the drill bit 3 is detachably connected to the end part of the adapter part 1-1 by the matching of the screw and the screw hole; and the joint of the drill bit 3 and the adapter part 1-1 is arranged in a clearance way.

Preferably, the adapter 1-1 and the drill 3 have through-holes 4 on their side walls.

As a preferable scheme, furthermore, the joint of the drill bit 3 and the adapter part 1-1 is matched with a sawtooth meshing structure, so that the connection firmness of the drill bit 3 and the adapter part 1-1 is effectively improved.

The working principle of the specific embodiment is as follows: the drill bit 3 is fixedly connected with the adapter part 1-1 of the double-edge cutter bar 1 by screws, and the drain holes 4 formed in the side wall are communicated into a whole for draining water; because the drill bit 3 and the adapter part 1-1 are arranged in a clearance-avoiding way, namely a gap 5 is arranged between the contact surfaces of the drill bit 3 and the adapter part 1-1, the drill bit 3 with different specifications can be conveniently installed on the adapter part 1-1, and the processing diameter and efficiency are improved; the arrangement of the double-edge cutter bar 1 is more convenient for drilling and chip removal.

Compared with the prior art, the beneficial effects of the embodiment are as follows:

1. the arrangement of the drain hole is adopted, so that the drainage and chip removal in the drilling process are facilitated;

2. the drill bit and the double-edge cutter bar are detachably connected by using the screw, so that the drill bit is convenient to replace;

3. adopt to keep away the empty setting, the twolip cutter arbor of being convenient for matches the drill bit of different specifications, and the suitability is wider, improves processing doubly footpath and efficiency.

It will be appreciated by those skilled in the art that modifications and equivalents may be made to the embodiments described above, and that various modifications, equivalents, improvements and the like may be made without departing from the spirit and scope of the invention.
