Description

Technical Field

[0001] This utility model belongs to the field of diamond drilling technology, and in particular relates to a diamond drilling drill for drilling holes in reinforced concrete. Background Technology

[0002] Diamond, a mineral composed of carbon, is the hardest substance in nature and has many important industrial applications, such as fine abrasive materials, high-hardness cutting tools, various drill bits, wire drawing dies, and components of many precision instruments. It is a material with excellent properties including superhardness, wear resistance, thermal sensitivity, thermal conductivity, semiconductor properties, and light transmission. Due to its high hardness, diamond is mainly used in industry to manufacture drilling probes and grinding tools, with diamond-based drill bits being widely used.

[0003] The existing technology still has the following shortcomings:

[0004] Most existing drill bits are made in one piece, and the tip of the drill bit is prone to wear due to long-term drilling operations, which leads to the scrapping of the drill bit and reduces its service life. Utility Model Content

[0005] This utility model provides a diamond drilling drill for drilling holes in reinforced concrete, aiming to solve the problem that most existing drill bits are made in one piece, and the end of the drill bit is easily worn due to long-term drilling operations, which leads to the scrapping of the drill bit and reduces its service life.

[0006] This utility model is implemented as follows: a diamond drilling drill for drilling holes in reinforced concrete includes: a first section rod, a connecting rod at the lower end of the first section rod, and a second section rod at the lower end of the connecting rod; the first section rod and the connecting rod are threadedly connected, and the second section rod and the connecting rod are detachably and fixedly connected; a protective layer is provided on the outside of the first section rod, the second section rod, and the connecting rod.

[0007] Preferably, the lower end of the second rod is fixedly connected to an annular truncated cone; several water channels are evenly arranged on the outer side of the annular truncated cone; and several diamond cutting heads are fixedly connected to the bottom of the annular truncated cone.

[0008] Preferably, each of the diamond cutting tips is located between two of the water channels.

[0009] Preferably, some diamond cutting tips have beveled teeth on one side.

[0010] Preferably, the first section rod, the second section rod, and the connecting rod are hollow inside, and the second section rod has a water outlet hole, which corresponds to the water passage groove.

[0011] Preferably, a narrow groove is formed on one side of the lower end of some of the diamond cutting tips.

[0012] Compared with the prior art, the embodiments of this application have the following main advantages:

[0013] By incorporating detachable first, connecting, and second sections, disassembly is facilitated, avoiding the need to replace the connecting and grinding parts of a single-piece structure. The inclusion of water channels enhances chip removal and cooling capabilities, thereby improving the sharpness of the diamond cutting tip. The helical teeth provide an angled cut to the workpiece surface, resulting in faster drilling speeds and higher processing efficiency compared to straight-tooth drills. Water outlets on the drill rod allow for timely cooling of the diamond cutting tip during drilling, extending its lifespan. Attached Figure Description

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This utility model embodiment provides a diamond drilling drill for drilling holes in reinforced concrete, such as... Figure 1-3 As shown, it includes: a first rod 1, a connecting rod 2 at the lower end of the first rod 1, and a second rod 4 at the lower end of the connecting rod 2; the first rod 1 and the connecting rod 2 are threaded together, and the second rod 4 and the connecting rod 2 are detachably and fixedly connected; the first rod 1, the second rod 4 and the connecting rod 2 are all provided with a protective layer on the outside.

[0021] It should be noted that since most existing drill bits are made in one piece, the end of the drill bit is prone to wear due to long-term drilling operations, which leads to the scrapping of the drill bit and reduces its service life. This solution is made by setting up a detachable first section rod 1, connecting rod 2 and second section rod 4, which facilitates disassembly and avoids replacing the connecting part and grinding part of the one-piece structure together.

[0022] In a further preferred embodiment of this utility model, such as Figure 1-3 As shown, a frustum 5 is fixedly connected to the lower end of the second rod 4; several water channels 6 are evenly arranged on the outer side of the frustum 5; several diamond cutter heads 7 are fixedly connected to the bottom of the frustum 5.

[0025] In this embodiment, chip removal is facilitated.

[0026] In a further preferred embodiment of this utility model, such as Figure 1-3 As shown, several diamond cutter tips 7 have helical teeth on one side.

[0027] In this embodiment, by setting helical teeth with an inclination and a better cutting angle on the workpiece surface, the drilling speed is faster and the processing efficiency is higher than that of straight-tooth drill bits.

[0028] In a further preferred embodiment of this utility model, such as Figure 1 As shown, the first rod 1, the second rod 4 and the connecting rod 2 are hollow inside, and the second rod 4 has a water outlet hole, which corresponds to the water channel 6.

[0029] In this embodiment, a water outlet hole is opened on the drill rod, which can cool the diamond cutter head 7 in time during the drilling process and extend the life of the diamond cutter head 7.

[0030] In a further preferred embodiment of this utility model, such as Figure 1-3As shown, a narrow groove 8 is provided on one side of the lower end of several diamond cutter heads 7.

[0031] In this embodiment, heat dissipation and chip removal are facilitated.
