Description

Technical Field

[0001] This utility model relates to the technical field of drilling machine tapping equipment, and in particular to a drilling machine tapping anti-jamming device. Background Technology

[0002] Buses are common vehicles. When repairing them, it is necessary to re-thread some brake drums or other parts. Usually, a drilling machine is used to re-thread the brake drums or other parts. The current method is to re-thread them manually, which is inefficient.

[0003] The existing method is to mount the tap on a drilling machine, which drives the tap to rotate and thread the tap through the hole. However, due to the large torque of the drilling machine and the fact that the output end of the drilling machine is directly connected to the tap, the tap often breaks off in the thread hole of the brake or other accessories during the threading process, making it difficult to remove the broken tap.

[0012] Furthermore, the diameter of the second mounting hole is larger than the diameter of the second through hole.

[0013] Furthermore, the second friction ring is disposed within the second mounting hole.

[0014] Furthermore, the connecting column includes a disc body and a shaft body. One end face of the disc body is in contact with the end face of the first friction disc, and the other end of the disc body is fixedly connected to the shaft body.

[0023] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a tapping anti-jamming device for a drilling machine, the device comprising:

[0024] The connecting component includes a lathe connector 11, a connecting rod 12, a first disc 13, and a connecting bolt 14. One end of the connecting rod 12 is fixedly connected to the first disc 13, and the other end is threadedly connected to the lathe connector 11. The first disc 13 is provided with a first through hole 15, and the connecting bolt 14 passes through the first through hole 15. A first groove 16 is provided at the end of the first disc 13 away from the connecting rod 12.

[0025] The friction component includes a second disc body 21, a connecting post 22, a first friction disc 23, and a second friction ring 24. The second disc body 21 is provided with a second threaded groove 25, and one end of the connecting bolt 14 is threadedly connected to the second threaded groove 25. The first friction disc 23 is disposed in the first groove 16. The second disc body 21 is provided with a second hole 26 at one end near the first disc body 13, and the second friction ring 24 is disposed in the second hole 26. One end of the connecting post 22 is attached to the first friction disc 23, and the other end passes through the second friction ring 24 and the second disc body 21.

[0026] The fixing component 3 has one end detachably connected to the tap 9 and the other end fixedly connected to the other end of the connecting post 22.

[0027] In the technical solution provided by this utility model embodiment, the connecting component functions to connect the drilling machine. The connecting component includes a lathe connecting part 11, a connecting rod 12, a first disc body 13, and a connecting bolt 14. One end of the connecting rod 12 is fixedly connected to the first disc body 13, and the other end is threadedly connected to the lathe connecting part 11. The first disc body 13 is provided with a first through hole 15, and the connecting bolt 14 passes through the first through hole 15. A first groove 16 is provided at the end of the first disc body 13 away from the connecting rod 12. The friction component functions to adjust the torque between the connecting component and the fixed component 3 through friction. The friction component includes a second disc body 21, a connecting post 22, a first friction disc 23, and a second friction ring 24. The second disc body 21 is provided with a second threaded groove 25, and one end of the connecting bolt 14 is threadedly connected to the second threaded groove 25. The first friction disc 23 is disposed in the first groove 16. A second hole 26 is provided at the end of the second disc body 21 near the first disc body 13, and the second friction ring 24 is disposed in the second hole 26. One end of the connecting post 22 is attached to the first friction disc 23. The disc 23 has one end passing through the second friction ring 24 and the second disc body 21; the fixing component 3 is used to fix the tap 9. One end of the fixing component 3 is detachably connected to the tap 9, and the other end is fixedly connected to the other end of the connecting post 22. Compared with the prior art, the tap 9 is mounted on a drilling machine, and the drilling machine drives the tap 9 to rotate to pass through the threaded hole. However, due to the large torque of the drilling machine and the fact that the output end of the drilling machine is directly connected to the tap 9, the tap 9 often breaks in the threaded hole of the brake or other accessories during the threading process, resulting in broken taps. Since tap 9 is difficult to remove, this technical solution involves installing a first friction disc 23 and a second friction ring 24 at both ends of the connecting column 22. The first disc body 13 and the second disc body 21 clamp the first friction disc 23, the connecting column 22, and the second friction ring 24. The gap between the first disc body 13 and the second disc body 21 is adjusted by the connecting bolt 14. When tap 9 gets stuck during the tapping process, the output end of the drill can still drive the connecting component to rotate, while the connecting column 22, the fixing component 3, and the tap 9 stop rotating, thereby achieving the technical effect of preventing tap 9 from breaking.

[0028] The aforementioned connecting component serves to connect the drilling machine. The connecting component includes a lathe connecting part 11, a connecting rod 12, a first disc body 13, and a connecting bolt 14. One end of the connecting rod 12 is fixedly connected to the first disc body 13, and the other end is threaded to the lathe connecting part 11. The first disc body 13 has a first through hole 15 through which the connecting bolt 14 passes. A first groove 16 is provided at the end of the first disc body 13 away from the connecting rod 12. One end of the connecting part 11 is connected to the connecting rod 12 through a threaded hole, and the other end is installed at the output end of the drilling machine. The connecting rod 12 is installed on the first disc body. On the axis of 13, specifically, one end of the connecting rod 12 is fixedly connected to the axis of the first disc 13 by welding, and the other end is provided with an external thread, which is threaded to the connecting member 11. Symmetrical first through holes 15 are provided on the side of the first disc 13, and the number of first through holes 15 is two or four. The connecting bolt 14 passes through the first through holes 15 and is connected to the second disc 21. The function of the friction component is to adjust the torque between the connecting component and the fixed component 3 through friction. The friction component includes the second disc 21, the connecting column 22, the first friction disc 23 and the second friction ring 24. The second disc 21 is provided with a second thread. The connecting bolt 14 is threaded into the second threaded groove 25. The first friction disc 23 is disposed in the first groove 16. The second disc body 21 has a second hole 26 at one end near the first disc body 13. The second friction ring 24 is disposed in the second hole 26. One end of the connecting post 22 is attached to the first friction disc 23, and the other end passes through the second friction ring 24 and the second disc body 21. The second hole 26 is provided at one end of the second disc body 21. The second hole 26 includes a second mounting hole and a second through hole. The second mounting hole is disposed in the second disc body 21. The second friction ring 24 is disposed in the second mounting hole near one end of the first disc 13, and the diameter of the second mounting hole is larger than the diameter of the second through hole. One end of the connecting post 22 is clamped between the first friction disc 23 and the second friction ring 24. Specifically, the connecting post 22 includes a disc body and a shaft body. One end face of the disc body is in contact with the end face of the first friction disc 23. The other end of the disc body is fixedly connected to the shaft body. The end face of the second friction ring 24 is in contact with the other end face of the disc body. One end of the shaft body passes through the second friction ring 24 and the second through hole and is connected to the fixing component 3.The function of the fixing component 3 is to fix the tap 9. One end of the fixing component 3 is detachably connected to the tap 9, and the other end is threadedly connected to the other end of the connecting post 22. The fixing component 3 is an existing drill chuck, which can hold the tap 9 and fix it. During installation, the output end of the drill press is connected to the connecting piece 11, and then the connecting bolt 14 is gradually tightened to shorten the gap between the first disc 13 and the second disc 21, so that one end face of the disc body is in contact with one end face of the first friction disc 23, and the other end face of the first friction disc 23 is in contact with the bottom surface of the first groove 16. At the same time, the other end face of the disc body is in contact with one end face of the second friction ring 24, and the other end face of the second friction ring 24 is in contact with the bottom surface of the second mounting hole. During tapping... The output end of the drill press drives the connecting piece 11, connecting rod 12, and first disc 13 to rotate. Under the frictional force of the first friction disc 23 and the second friction ring 24, the connecting column 22 rotates. The connecting column 22 drives the fixing part 3 and tap 9 to rotate, and the tap 9 taps the threaded hole. When the tap 9 is stuck and stops rotating, because the frictional force between the first friction disc 23 and the connecting column 22, and between the second friction ring 24 and the connecting column 22, is less than the torque at the output end of the drill press, and because the first disc 13 and the connecting column 22 are not rigidly connected, the connecting column 22 and the fixing part 3 stop rotating, while the connecting piece 11, connecting rod 12, first disc 13, and second disc 21 continue to rotate, thereby achieving the technical effect of preventing the tap 9 from breaking.

[0029] Furthermore, a first post 17 is provided on the first disc body 13, and a second through hole 27 is provided on the second disc body 21, with the first post 17 inserted into the second through hole 27. In this embodiment, a first disc 13 is further defined, and a first pillar 17 is provided on the end face of the first disc 13. The first main body is located on the side of the first groove 16 and is perpendicular to the first disc 13. At the same time, a second through hole 27 is provided at the end of the second disc 21 near the first disc 13. The diameter of the second through hole 27 is slightly smaller than the diameter of the first pillar 17, so that the first pillar 17 can be inserted into the second through hole 27. There are two first pillars 17, and the two first pillars 17 are arranged symmetrically about the axis of the first disc 13. The second through hole 27 is provided on the side of the second threaded groove 25 away from the second hole 26. The two second through holes 27 are arranged symmetrically about the axis of the second disc 21, thereby achieving the technical effect of fixing the first disc 13 and the second disc 21 relatively, and reducing the torque on the connecting bolt, thereby protecting the connecting bolt.
