[0036] like Figure 1-Figure 3As shown, in this embodiment, the drilling sampling tool includes a cutter head 1, a push rod assembly and a fixing member 5. The cutter head 1 has a receiving cavity 11, and the cutter head 1 is provided with a sampling port 12. The push rod assembly includes a tool handle 2, a push plate 3 and a connecting rod 4. The connecting rod 4 and the tool handle 2 are both penetrated through the bottom of the cutter head 1 and connected to the push plate 3. The tool handle 2 is used for an external clamp. The push plate 3 is located in the receiving cavity 11, and the push plate 3 can slide relative to the cutter head 1 along the length direction of the tool handle 2, so that the sample in the receiving cavity 11 can be taken out through the sampling port 12. The fixing member 5 can be sleeved on the connecting rod 4, and the fixing member 5 can rotate relative to the connecting rod 4, so that the cutter head 1 is separated from the push rod assembly. Specifically, the cutter head 1 has a receiving cavity 11, that is, the cutter head 1 is a hollow cylindrical structure. The common diameter sizes of the cutter head 1 are 28.5 mm and 99.5 mm. According to the actual cutting requirements, diameter sizes including but not limited to 20 to 100 mm can also be used. In addition, the length requirement of the cutter head 1 depends on the thickness of the sample. A sampling port 12 is provided at one end of the cutter head 1. The sampling port 12 is used to drop the cut sample into the receiving cavity 11. A push rod assembly is provided at the other end of the cutter head 1, wherein the diameter of the handle 2 is 12 mm and the length ranges from 50 to 70 mm. The tail of the handle 2 is aligned with the hole position of the fixture and then fixed by snap-fitting. The cross-sectional shape of the push plate 3 is the same as the circular cross-sectional shape of the cutter head 1, so that the push plate 3 can match the cutter head 1. The height of the push plate 3 is 5 to 8 mm, and the diameter of the push plate 3 is 17 to 97 mm. The push plate 3 is slidably arranged in the receiving cavity 11. The connecting rod 4 is 10 to 20 mm long and 8 mm in diameter. The fixing part 5 is rotatably mounted on the connecting rod 4 and can move along the length direction of the connecting rod 4. When the fixing part 5 is pressed against the bottom end face of the cutter head 1, the push rod assembly is locked relative to the cutter head 1. When the fixing part 5 is separated from the connecting rod 4, the push rod assembly can be completely separated from the cutter head 1, which is convenient for disassembly and replacement of the cutter head 1 or the push rod assembly. There is no need to replace the entire set of tools, thereby reducing the maintenance cost of the tools. When using the drilling sampling tool to cut the sample, first screw the fixing part 5 on the connecting rod 4, so that the connecting rod 4 and the fixing part 5 connected by the push plate 3 of the cutter head 1 and the handle 2 are pre-tightened but not tightened, and then the handle 2 is fixedly connected to the clamp of the tapping machine. After the sample is placed, tighten the fixing part 5, lock the push rod assembly relative to the cutter head 1, the cutter head 1 contacts the sample and drills a hole under the rotation of the tapping machine, and the cut sample is placed in the accommodating cavity 11 of the cutter head 1. When sampling is required, loosen the fixing part 5 and keep the fixing part 5 away from the bottom of the cutter head 1, and the push plate 3 slides relative to the cutter head 1 under the action of the handle 2 to quickly press the sample in the accommodating cavity 11 out of the sampling port 12 to avoid damage to the sample surface due to excessive local stress and ensure the accuracy of the sample test data.
[0037] Further, continue to refer to Figure 1-Figure 3The bottom of the cutter head 1 is provided with a through hole 13 and a connecting hole 14, the handle 2 can be slidably penetrated in the through hole 13, and the connecting rod 4 can be slidably penetrated in the connecting hole 14. Specifically, there are multiple connecting holes 14, the number of connecting rods 4 is the same as the number of connecting holes 14, and multiple connecting rods 4 are arranged one by one with multiple connecting holes 14. In this embodiment, the bottom center and side of the cutter head 1 are respectively provided with a through hole 13 and two connecting holes 14, and the number of connecting rods 4 is two. The handle 2 penetrates the through hole 13 and is connected to the push plate 3, and the two connecting rods 4 pass through the corresponding connecting holes 14 and are connected to the push plate 3. The handle 2, the connecting rod 4 and the push plate 3 are integrally formed by casting or the like, and the connection is firm and the structure is stable. The diameter of the through hole 13 corresponds to the diameter of the handle 2, so that the handle 2 can slide through the through hole 13. The diameter of the connecting hole 14 is smaller than the diameter of the fixing member 5, so that the fixing member 5 can be screwed tightly against the bottom of the cutter head 1. Optionally, the number of the connection holes 14 is determined according to actual needs, and is generally 1 to 3.
[0038] Further, continue to refer to Figure 1-Figure 3 The fixing member 5 is configured as a nut, the outer periphery of the connecting rod 4 is provided with an external thread, the hole wall of the fixing member 5 is provided with an internal thread, and the connecting rod 4 and the fixing member 5 are threadedly connected via the external thread and the internal thread. Specifically, the fixing member 5 is threadedly connected to the connecting rod 4, and the fixing member 5 can move along the length direction of the connecting rod 4. When the fixing member 5 is pressed against the bottom end face of the cutter head 1, the push rod assembly is locked relative to the cutter head 1. When the fixing member 5 is separated from the connecting rod 4, the push rod assembly can be completely separated from the cutter head 1, which is convenient for disassembly and replacement of the cutter head 1 or the push rod assembly, without the need to replace the entire set of tools, thereby reducing the maintenance cost of the tools.
[0039] Further, continue to refer to Figure 1-Figure 3 The fixture is provided with a fixing hole, and the tool handle 2 is clamped and fixed in the fixing hole. Specifically, the cross-sectional shape of the tool handle 2 is a triangular structure, and the fixing hole shape of the corresponding tapping machine fixture is set to be a triangle. The tail of the tool handle 2 is aligned with the fixing hole and then clamped and fixed, which can realize the quick insertion and removal of the tool and the fixture, and is easy to operate.
[0040] This embodiment also provides a mechanical processing equipment, including a fixture and the above-mentioned drilling sampling tool, and the drilling sampling tool is installed on the fixture. Specifically, the mechanical processing equipment is a tapping machine or a rocker-type die-cutting machine, etc. The fixture is fixedly connected with the handle 2 of the drilling sampling tool, the mechanical processing equipment is started, and drilling is performed under the rotation of the fixture of the tapping machine. The cut sample is placed in the accommodating cavity 11 of the cutter head 1. When sampling is required, the fixing member 5 is loosened and the fixing member 5 is separated from the bottom of the cutter head 1. The push plate 3 slides relative to the cutter head 1 under the action of the handle 2 to quickly press the sample in the accommodating cavity 11 out of the sampling port 12, so as to avoid damage to the sample surface due to excessive local stress, and ensure the accuracy of the sample test data. When the cutter head 1 reaches a certain degree of wear and needs to be repaired and replaced, the fixing member 5 is separated from the connecting rod 4, so that the push rod assembly can be completely separated from the cutter head 1, which is convenient for disassembly and replacement of the cutter head 1 or the push rod assembly, without the need to replace the entire set of tools, thereby reducing the maintenance cost of the tool.
