Description

Technical Field

[0001] This utility model relates to the field of machinery, specifically a portable internal thread repair machine. Background Technology

[0002] In actual production, damage to internal threads occurs frequently and often needs to be repaired in a short time to ensure the normal operation of the equipment.

[0003] Some current internal thread repair equipment requires machining on a boring machine, which increases processing costs and reduces efficiency. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, this utility model provides a portable internal thread repair machine.

[0005] The technical solution adopted by this utility model is as follows:

[0006] A portable internal thread repair machine includes a repair cylinder. The front sidewall of the repair cylinder has a damaged thread hole in its center. Four flange holes are evenly distributed around the damaged thread hole on the front sidewall of the repair cylinder. Four optical shafts are located on the front side of the repair cylinder, and connectors are fixedly connected to the rear ends of each optical shaft. The four connectors are threaded into the four flange holes. Each of the four optical shafts has a first positioning ring and a second positioning ring. The first positioning ring is located behind the second positioning ring. Four evenly distributed sliding holes are formed on the front sidewall of both the first and second positioning rings. Four optical axes pass through the four sliding holes of positioning ring one and positioning ring two, respectively. Each optical axis slides into the sliding hole. The inner wall of positioning ring two is fixedly connected to a mounting plate, and the inner wall of positioning ring one is fixedly connected to a fixing frame. The fixing frame is cross-shaped. The front wall of the mounting plate is fixedly connected to a handle, and the rear wall of the mounting plate is fixedly installed with a reduction motor. The rear end of the output shaft of the reduction motor is fixedly connected to the front end of the connecting shaft. The rear end of the connecting shaft passes through the fixing frame and is rotatably connected to the fixing frame. The rear end of the connecting shaft is fixedly connected to a tap, which is adapted to the damaged threaded hole.

[0007] The beneficial effects of this utility model are:

[0008] This invention is easy to carry and move, and is suitable for various workplaces. By adjusting the positions of positioning ring one and positioning ring two on the optical axis, it can flexibly adapt to damaged threaded holes of different positions and sizes. It can bore and ream damaged threaded holes, solving the problem that internal thread boring and reaming repair does not require machining on a boring machine, thus reducing processing costs and improving efficiency.

[0009] Using a geared motor to drive the tap for boring and reaming operations greatly improves repair efficiency and quality. The positioning ring and its attached components can be easily pushed to perform repair operations by holding the handle, making the operation simple and easy to understand.

[0015] like Figure 1-4 As shown: A portable internal thread repair machine includes a repair cylinder 1. The front sidewall of the repair cylinder 1 has a damaged thread hole 2 in the middle. Four flange holes 3 are evenly distributed around the damaged thread hole 2 on the front sidewall of the repair cylinder 1. Four optical shafts 4 are located on the front side of the repair cylinder 1. Connecting heads 5 are fixedly connected to the rear ends of each optical shaft 4. The four connecting heads 5 are threaded into the four flange holes 3 respectively. Each of the four optical shafts 4 has a first positioning ring 6 and a second positioning ring 7. The first positioning ring 6 is located behind the second positioning ring 7. Four sliding holes 8 are evenly distributed on the front sidewall of both the first positioning ring 6 and the second positioning ring 7. The four optical shafts 4 are... Do not pass through the four sliding holes 8 of positioning ring 1 6 and positioning ring 2 7. Each optical axis 4 is slidably engaged with the sliding hole 8. The inner side wall of positioning ring 2 7 is fixedly connected to the mounting plate 9. The inner side wall of positioning ring 1 6 is fixedly connected to the fixing bracket 10. The fixing bracket 10 is cross-shaped. The front side wall of mounting plate 9 is fixedly connected to the handle 11. The rear side wall of mounting plate 9 is fixedly installed with the reduction motor 12. The rear end of the output shaft of reduction motor 12 is fixedly connected to the front end of connecting shaft 13. The rear end of connecting shaft 13 passes through the fixing bracket 10. Connecting shaft 13 is rotatably connected to fixing bracket 10. The rear end of connecting shaft 13 is fixedly connected to tap 14. Tap 14 is adapted to the damaged thread hole 2.

[0016] Take the portable internal thread repair machine to the work site where repair is needed, and confirm that the damaged thread hole 2 on the repair cylinder 1 matches the internal thread hole to be repaired.

[0017] The four optical axes 4 are threaded into the four flange holes 3 on the front side wall of the repair cylinder 1 through the connector 5 to ensure that the optical axes 4 are stable.

[0018] Positioning ring 6 and positioning ring 7 are respectively placed on the four optical axes 4 and slidably engaged with the optical axes 4 through the sliding hole 8. At this time, positioning ring 6 is located behind positioning ring 7.

[0019] The mounting plate 9, which is fixedly connected to the inner wall of the positioning ring 7, is equipped with a handle 11. By holding the handle 11, the positioning ring 7 and its attached components can be easily pushed back and forth.

[0020] By pushing the positioning ring 7 with handle 11, the tap 14 is aligned with the damaged thread hole 2.

[0021] As needed, the positions of positioning ring 16 and positioning ring 27 on the optical axis 4 can be finely adjusted to ensure that tap 14 can accurately enter the damaged wire hole 2.

[0022] Start the geared motor 12, and its output shaft drives the connecting shaft 13 and the tap 14 to rotate. While the tap 14 is rotating, the positioning ring 7 can be slowly pushed by the handle 11 so that the tap 14 gradually enters and passes through the damaged wire hole 2 to perform boring and wire reaming operations.

[0023] During boring, tap 14 removes damaged threads and enlarges the hole diameter; during reaming, tap 14 re-forms new threads within the enlarged hole diameter.

[0024] When the tap 14 has completely passed through the damaged hole 2 and achieved the expected repair effect, turn off the geared motor 12.

[0025] Remove positioning ring 2 7 and positioning ring 1 6, and remove the portable internal thread repair machine from the repair cylinder 1.
