Description

Technical Field

[0001] The utility model relates to a detachable integrated drilling and countersinking tool. Background Art

[0002] Drilling and countersinking are common processes in metal processing, mechanical manufacturing, and construction. Drills are used to create holes in materials, while countersinks are used to accurately countersink the bottom of the drilled holes to facilitate subsequent threaded connections or assembly operations. Traditional drilling and countersinking tools are mostly two independent units, namely drills and countersinks, which need to be used in different operation steps.

[0003] Although the independent drill and countersink in the prior art can perform their respective functions, this separate design has some inefficiencies. First, it takes extra time to change tools, which reduces work efficiency. Second, repeated positioning may introduce precision errors, especially when aligning multiple holes in dense or narrow spaces. In addition, for operating environments where tools are frequently switched, the labor intensity and complexity of operators are increased.

[0004] In order to solve the above problems, integrated drilling and countersinking tools have appeared on the market. These tools combine the drill tip and the countersink on one tool body, reducing the time for tool replacement and improving work efficiency. However, existing drilling and countersinking tools are usually fixed in design, and the countersink cannot be easily adjusted or replaced according to different work requirements, which limits the flexibility and scope of application of the tools. Utility Model Content

[0005] The main purpose of the utility model is to provide a detachable integrated drilling and countersinking tool to solve the problems raised in the above-mentioned background technology.

[0006] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0007] A detachable integrated drill and countersinking tool comprises a drill tip and a drill shank, wherein a plurality of countersinks are arranged on the outside of the drill shank near the drill tip along its circumference, the drill shank and the countersinks are connected by a fixing tube, the fixing tube is provided with a first connecting hole, and the drill shank is provided with a second connecting hole.

[0008] Preferably, the outer side of the countersink is an inclined surface, and the outer side of the countersink gradually tilts outward from a side close to the drill tip to a side close to the drill shank.

[0009] Preferably, two countersinks are provided.

[0010] Preferably, the two countersinks are symmetrically arranged on the fixed tube.

[0011] Preferably, two of the first connection holes and two of the second connection holes are provided.

[0012] Preferably, the two first connecting holes are symmetrically arranged on the fixing tube, and the two second connecting holes are symmetrically arranged on the drill handle.

[0013] Preferably, a slide groove is provided on the drill shank along its length direction, and a sliding block used in conjunction with the slide groove is provided on the inner side of the fixed tube.

[0014] Preferably, two slide grooves are provided, and the two slide grooves are arranged on the drill shank and evenly distributed along the circumference thereof.

[0015] Beneficial technical effects of the utility model:

[0016] The drill shank and countersink provided by the utility model can be easily separated and connected through a fixing tube, allowing the user to quickly replace countersinks of different specifications to meet various processing needs without replacing the entire tool. When the countersink is damaged or worn, the countersink can be replaced alone instead of the entire tool. This detachable design improves the versatility and adaptability of the tool, while optimizing maintenance costs and resource utilization efficiency. At the same time, the design of the slide and the slider ensures that the positioning of the countersink on the tool is both accurate and stable, simplifying the assembly and disassembly process of the tool.

[0022] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0023] like Figure 1-Figure 4As shown, the detachable integrated drill and countersink tool provided in this embodiment includes a drill tip 1 and a drill shank 2. A plurality of countersinks 3 are arranged along the circumference of the outer side of the drill shank 2 close to the drill tip 1. The drill shank 2 and the countersinks 3 are connected by a fixing tube 4. A first connecting hole 5 is arranged on the fixing tube 4. A second connecting hole 6 is arranged on the drill shank 2. Both the first connecting hole 5 and the second connecting hole 6 are threaded holes, which are connected by bolts to realize the detachable function. The operator can quickly replace the countersinks 3 of different specifications to adapt to different processing requirements without replacing the entire tool.

[0024] In this embodiment, if Figure 1 As shown, the outer side of the countersink 3 is an inclined surface, and the outer side of the countersink 3 gradually tilts outward from the side close to the drill tip 1 to the side close to the drill shank 2, so that the countersinking operation can be completed smoothly.

[0025] In this embodiment, if Figure 1 As shown, two countersinks 3 are provided, and the two countersinks 3 are symmetrically arranged on the fixed tube 4, which helps to balance the force of the tool during the processing, thereby improving the processing accuracy and surface quality.

[0026] In this embodiment, if Figure 3 and Figure 4 As shown, two first connecting holes 5 and two second connecting holes 6 are provided, the two first connecting holes 5 are symmetrically arranged on the fixing tube 4, and the two second connecting holes 6 are symmetrically arranged on the drill shank 2, which simplifies the assembly process, allows fast and accurate alignment, ensures a firm connection between the components, and improves the overall rigidity of the tool.

[0027] In this embodiment, if Figure 3 and Figure 4 As shown, a slide groove 7 is provided on the drill shank 2 along its length direction, and a slider 8 used in conjunction with the slide groove 7 is provided on the inner side of the fixed tube 4, providing a fast and accurate positioning mechanism, which not only facilitates the operator to quickly replace the countersink 3, but also ensures that the replaced countersink 3 is accurately positioned, thereby maintaining the processing quality.

[0028] In this embodiment, if Figure 1 As shown, two slide grooves 7 are provided, and the two slide grooves 7 are arranged on the drill shank 2 and are evenly distributed along its circumference, which further optimizes the transmission and distribution of force, makes the tool more stable during processing, and reduces tool wear and deformation caused by uneven force.

[0029] In summary, in this embodiment, the drill shank 2 and the countersink 3 provided in this embodiment can be easily separated and connected through the fixing tube 4, allowing the user to quickly replace the countersink 3 of different specifications to adapt to various processing needs without replacing the entire tool. When the countersink 3 is damaged or worn, the countersink 3 can be replaced alone instead of the entire tool. This detachable design improves the versatility and adaptability of the tool, while optimizing maintenance costs and resource utilization efficiency. At the same time, the design of the slide 7 and the slider 8 ensures that the positioning of the countersink 3 on the tool is both accurate and stable, simplifying the assembly and disassembly process of the tool.

[0030] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
