Description

Technical Field

[0001] This utility model relates to the field of drill bit technology, and in particular to a woodworking positioning drill bit. Background Technology

[0002] Modern society produces many wooden products, such as furniture and decorative items. Drilling machines are commonly used in wood processing. A drilling machine includes a drill bit, which consists of a shank and a working part. The end of the working part furthest from the shank is the drill head, the part where the drill bit first contacts the wood. To improve drilling positioning, a woodworking drill bit, as disclosed in Chinese utility model patent CN219027830U, includes a working part and a shank at one end of the working part. The end of the working part furthest from the shank has a conical drill tip with threads on its outer wall. During drilling, the drill tip provides positioning, and chips are removed through a chip removal groove. This type is suitable for drilling deep holes, but it cannot meet the needs of enlarged holes. Therefore, improvements are necessary. Utility Model Content

[0026] In the description of this utility model, it should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to or indirectly connected to the other element.

[0027] In the description of this utility model, it should be noted that the terms "center," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified. "Several" means one or more, unless otherwise explicitly specified.

[0028] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, 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 merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0030] Example 1: See Figure 1A woodworking positioning drill bit includes a drill shank 1. The front end face of the drill shank 1 is provided with evenly spaced reaming drill bits 2. The reaming drill bits 2 and the drill shank 1 are integrally formed, which can not only enlarge holes, but also meet the needs of use. Moreover, the structure is more robust and greatly improves the service life. A positioning drill 3 is provided at the joint of the drill bits 2, which has a better positioning effect and greatly improves the drilling accuracy.

[0031] Example 2: This can be explained based on Example 1, such as... Figure 2 and Figure 3 As shown, the reaming drill bit 2 can be used in two or three different types, offering a wide range of choices and better meeting usage needs.

[0032] like Figure 2 , Figure 3 and Figure 4 As shown, the reaming drill bit 2 includes a body 21 disposed on the front end face of the drill shank 1. A drill bit 22 is disposed on the outer circular arc surface of the body 21. A cutting blade 23 is disposed on one side of the body 21, while the other side of the body 21 is configured as an inclined surface 24. The upper end face of the cutting blade 23 is higher than the upper end face of the inclined surface 24. This is beneficial for the cutting blade 23 to remove chips through the inclined surface 24 after cutting. It can be seen that the drill bit 22 and the cutting blade 23 are more conducive to cutting and reaming, and are more conducive to meeting the usage requirements.

[0033] like Figure 2 , Figure 3 and Figure 4 As shown, the upper end face of the drill bit 22 is arrow-shaped, which is beneficial for cutting. Furthermore, the body 21, drill bit 22, and cutting insert 23 are all integrally formed, greatly improving the structural robustness.

[0034] like Figure 2 , Figure 3 and Figure 4 As shown, to further illustrate, each cutting blade 23 is evenly distributed on the positioning drill 3 at regular intervals. This arrangement is beneficial for cutting after positioning.

[0035] Example 3: This can be described based on Example 1 or Example 2, such as... Figure 4 As shown, grooves are provided at the joints of each reaming drill bit 2, and positioning drills 3 are installed in the grooves. The positioning drills 3 and the grooves are welded together, which greatly improves the robustness of the welded structure and facilitates quick positioning and installation of the positioning drills 3. Furthermore, the positioning drills 3 are provided with external threads, which is beneficial for depth positioning after initial positioning and also facilitates drilling.

[0036] Example 4: This can be described based on Example 1, Example 2, or Example 3, such as... Figure 5As shown, the rear end face of the drill shank 1 has an internal thread groove 11, which is beneficial for connecting with external devices.

[0037] All standard parts used in this application can be purchased from the market, and the specific connection methods of each part adopt conventional methods such as bolts and rivets that are mature in the existing technology, which will not be described in detail here.

[0038] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
