Description

Technical Field

[0001] The utility model relates to the technical field of counterbore drills, in particular to a positioning counterbore drill. Background Art

[0002] Known counterbore drills are used for the processing of through holes. The counterbore processing effect is formed by cutting with the conical cutting edge on the counterbore drill on the top surface of the through hole. During the fixing process of the bolt, the head of the bolt can be embedded into the counterbore to form a fitting effect with the surface of the processing surface, and no convex state will occur. For existing counterbore drills, it is not easy to replace the drill bit. Therefore, different counterbore drills are required for drilling holes of different sizes. For example, a new type of counterbore drill disclosed in the Chinese utility model patent with the authorization announcement number CN220278368U includes a body, a center drill, a positioning member, and a fastener. A first chamber is provided in the body, a first opening is provided on the first chamber, the center drill extends into the first chamber from the first opening, a fixing hole is provided on the side wall of the first chamber, the positioning member is sleeved on the body, a positioning ring is provided at one end of the positioning member close to the center drill, a kidney-shaped hole is provided on the side wall of the positioning member, and the fastener passes through the kidney-shaped hole and the fixing hole and abuts against the center drill. Among them, the positioning member used to fix the center drill is unique, which is not conducive to the change of the center drill according to the required drilling, so it cannot meet the use requirements.

[0031] To make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0032] Embodiment 1: Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , a positioning counterbore drill, including a positioning member 1, a handle 2 with adjustable position is detachably installed on the positioning member 1, and a drill bit 3 is arranged at the front end of the handle 2. The drill bit 3 is detachably connected to the handle 2. The independent handle 2 can not only replace the drill bit 3 at will to meet the production requirements of different hole grooves, but also adjust the position of the handle 2 to suit the processing requirements of different hole groove depths.

[0033] In the present utility model, since a handle 2 with adjustable position is detachably installed on the positioning member 1, and a drill bit 3 is arranged at the front end of the handle 2, and the drill bit 3 is detachably connected to the handle 2, this is conducive to quickly replacing the drill bit 3 (counterbore drill) of different sizes, and is also conducive to quickly replacing the drill bit 3 (counterbore drill) after the hole is drilled.

[0034] Embodiment 2: It can be described on the basis of Embodiment 1, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, the positioning member 1 includes a sleeve 11 and an axial hole 12 arranged at the center of the sleeve 11, and an internal thread section is arranged in the axial hole 12, and the internal thread section is arranged with an internal thread, and the handle 2 includes a handle body 21, and the outer wall of the handle body 21 is provided with an external thread section 22, and the external thread section 22 is arranged with an external thread. The length of the external thread section 22 is greater than the internal thread section. This is not only conducive to the disassembly and installation of the handle 2 and the positioning member 1, but also can achieve rapid installation, and is also conducive to adjusting the position of the handle body 21 by moving the external thread section of the outer wall of the handle body 21 in the internal thread section, so as to meet the processing requirements of different hole depths. It is to be noted that the sleeve 11 is provided with waist-shaped holes 13 arranged in pairs, which is not only conducive to chip removal, but also can dissipate heat. It is also to be noted that a card slot 23 is provided on the handle body 21, and this setting is conducive to clamping and fastening with an external setting. The utility model adjusts the position of the handle body 21 by moving the external thread section of the outer wall of the handle body 21 in the internal thread section, which is not only convenient for disassembly and replacement, but also conducive to completing the replacement of the drill bit 3 in one go when drilling.

[0035] Among them, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a fastening sleeve 4 is provided on the external thread section, the fastening sleeve 4 is threadedly connected to the external thread section, and a protrusion 41 is provided on one end face of the fastening sleeve 4 that contacts the positioning member 1. This is more conducive to the handle 2 being installed on the positioning member 1 so that the protrusion 41 of the fastening sleeve 4 is fully in contact with the end face of the positioning member 1, and is more conducive to a tighter threaded connection between the handle 2 and the positioning member 1.

[0036] Embodiment 3: It can be described on the basis of Embodiment 1 or Embodiment 2, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a mounting groove 24 is provided on the end surface of the handle 2, and a magnetic attraction member is provided inside the mounting groove 24. The drill bit 3 and the mounting groove 24 are clearance-matched, which is not only conducive to the detachable connection between the drill bit 3 and the handle 2, but also allows the drill bit 3 to be replaced at will to meet the production price of different holes and slots, and is also conducive to connection through the magnetic attraction member. It should be noted that the magnetic attraction member is a magnet or a magnet, which is connected by magnetism, has a wide source, and is easy to implement.

[0037] Embodiment 4: It can be described on the basis of Embodiment 1, Embodiment 2 or Embodiment 3, such as Figure 8 and Figure 9 As shown, the drill bit 3 can be a two-end drill bit or a single-end drill bit, and there are various types, so there is a large room for selection, such asFigure 9 As shown, a magnet is provided at one end of a drill bit connected to the handle 2, which is more conducive to making the connection between the drill bit and the handle 2 tighter.

[0038] The standard parts used in this application document can all be purchased from the market. The specific connection methods of each part all adopt conventional means such as bolts and rivets that are mature in the prior art, and no specific description will be made here.
