Description

Technical Field

[0001] This utility model relates to the field of tapping technology, specifically to an adjustable universal tapping tool applicable to narrow spaces. Background Technology

[0002] Tapping refers to using a certain torque to screw a tap into the hole to be drilled to produce internal threads. Tapping tools are the devices that achieve this function.

[0003] Existing tapping tools are generally benchtop tapping drills or handheld tapping drills. Handheld tapping drills are advantageous due to their flexibility, convenience, lack of limitations, ability to tap at multiple angles, and portability. CN209754201U discloses a handheld plate tapping device, which includes a tapping machine housing and a tapping chuck. One side of the tapping chuck is fixedly connected to one side of the tapping machine housing via a fixedly mounted vise head. A mounting hole with an internal thread groove is fixedly opened in the middle of the other side of the tapping chuck. The tapping chuck passes through the internal thread groove... The tap is connected to the threaded groove. A first vertical handle is fixedly connected to one side of the bottom of the tapping machine housing. A lithium battery pack is fixedly installed inside the first vertical handle. A cylindrical interface is fixedly installed at the bottom of the first vertical handle. A second vertical handle is fixedly connected to the other side of the bottom of the tapping machine housing. A forward and reverse motor is fixedly installed on one side of the inner cavity of the tapping machine housing. A coupling is fixedly connected to the output end of the forward and reverse motor. A drive shaft is movably connected to one end of the coupling. One end of the drive shaft moves with the tapping chuck through a bearing.

[0004] In the existing technology, the distance between the tap and the tapping machine housing cannot be adjusted. As a result, when tapping is required in a narrow space during daily use, the tapping machine housing cannot enter the narrow space, which prevents the tap from contacting the position to be tapped. Therefore, the existing handheld tapping drill has defects and needs to be improved to meet the needs of tapping in both spacious and narrow spaces. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an adjustable universal tapping tool applicable to narrow spaces, thus solving the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an adjustable universal tapping tool for use in narrow spaces, including a tapping drill, the tapping drill being provided with a handle and an auxiliary grip, the left end of the tapping drill being provided with a bearing seat, the bearing seat being provided with a rotating drum, and a rotating shaft being slidably connected inside the rotating drum, the left end of the rotating shaft being provided with a chuck, and a tap being detachably connected to the chuck;

[0007] The rotating shaft is provided with evenly spaced screw holes, and the rotating cylinder is provided with bolts that connect to the screw holes;

[0008] A rotating ring is provided on the rotating shaft. The left end of the rotating ring is connected to the clamp. The rotating ring is located on the left side of the rotating cylinder and is connected to the rotating support assembly.

[0009] The rotating support assembly is provided with a clamping assembly for clamping the rotating ring.

[0010] Preferably, the rotating support assembly includes a mounting bracket, a bearing is provided at the left end of the mounting bracket, the outer wall of the rotating ring is connected to the bearing, and the right end of the mounting bracket is slidably connected to the tapping drill.

[0011] Preferably, the clamping assembly includes two mounting cylinders, which are located on the front and rear sides of the rotating ring respectively, and are connected to the front and rear sides of the mounting frame respectively. A spring and a sliding rod are provided inside the mounting cylinder. The sliding rod is slidably connected to the mounting cylinder and is connected to the spring. A mounting plate opposite to the rotating ring is provided on the sliding rod, and an arc-shaped anti-slip pad is provided on the mounting plate.

[0012] Preferably, the right end of the rotating ring is provided with a groove evenly circumferentially, and the groove is opposite to the anti-slip pad.

[0013] Preferably, the groove has a semi-circular structure.

[0014] Preferably, both ends of the left end of the rotating drum are provided with protrusions, and bolts are bolted to the protrusions.

[0015] This invention provides an adjustable universal tapping tool for use in confined spaces. Compared with the prior art, it has the following advantages:

[0016] 1. This adjustable universal tapping tool, applicable to narrow spaces, uses a tapping drill to drive a rotating drum, which in turn causes a bolt to rotate a rotating shaft. This, in turn, drives a tap to rotate and tap through a chuck. When the tapping drill cannot enter a narrow space, the bolt can be removed to pull out the rotating shaft, and then the bolt can be reinstalled. This increases the distance between the tapping drill and the tap, allowing the tapping drill to be used from the outside while the tap is still tapping. Thus, this application can meet the need for tapping in both spacious and narrow spaces, and has strong versatility.

[0017] 2. This adjustable universal tapping tool, designed for use in confined spaces, features a rotating ring at the left end of the spindle. The ring houses a bearing and a mounting bracket that slides with the tapping drill. This design does not affect the spindle's adjustable position. Even when the spindle extends to the left, the left side remains supported during rotation, ensuring stability of the left tap. By gripping the mounting plates on both sides, anti-slip pads hold the spindle in place. Even if the user rotates the spindle, the mounting cylinder on the sliding rod will obstruct the rotation, preventing both the spindle and cylinder from rotating during assembly. This allows for the insertion of bolts into the cylinder that correspond to the screw holes on the spindle, improving adjustment efficiency. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] See Figures 1-5 This utility model provides the following two technical solutions:

[0026] First implementation: An adjustable universal tapping tool for use in narrow spaces, including a tapping drill 1, a handle 2 and an auxiliary grip 3 on the tapping drill 1, a bearing seat 4 on the left end of the tapping drill 1, a rotating drum 5 on the bearing seat 4, the tapping drill 1 drives the rotating drum 5 to rotate by existing technology, and a rotating shaft 6 is slidably connected inside the rotating drum 5, a chuck 7 is provided on the left end of the rotating shaft 6, and a tap 8 is detachably connected to the chuck 7, the rotating shaft 6, the chuck 7 and the tap 8 rotate synchronously;

[0027] The rotating shaft 6 is evenly provided with screw holes 9, and the rotating cylinder 5 is provided with bolts 10 connected to the screw holes 9. When the rotating cylinder 5 rotates, the rotating shaft 6 is driven to rotate through the bolts 10. When the tapping drill 1 cannot enter a narrow space, the bolts 10 are removed and the rotating shaft 6 is pulled out. Then the bolts 10 are reinstalled, which increases the distance between the tapping drill 1 and the tap 8. This allows the tapping drill 1 to be able to tap the tap 8 from the outside. Thus, this application can meet the need for tapping in both spacious and narrow spaces, and has strong versatility.

[0028] When the rotating shaft 6 drives the tap 8 to move to the left, the left side of the rotating shaft 6 lacks support, which can easily cause the tap 8 to be unstable during rotation. Therefore, a rotating ring 13 is provided on the rotating shaft 6. The left end of the rotating ring 13 is connected to the chuck 7. The rotating ring 13 is located on the left side of the rotating cylinder 5 and is connected to the rotating support assembly.

[0029] The rotating support assembly is provided with a clamping assembly for clamping the rotating ring 13.

[0030] The rotating support assembly includes a mounting bracket 11, with a bearing 12 at the left end of the mounting bracket 11. The outer wall of the rotating ring 13 is connected to the bearing 12, and the right end of the mounting bracket 11 is slidably connected to the tapping drill 1. When the rotating shaft 6 rotates, the rotating ring 13 rotates under the support of the bearing 12. When the rotating ring 13 moves to the left with the rotating shaft 6, the mounting bracket 11 can drive the bearing 12 to move to the left as well, thereby ensuring support for the left side of the rotating shaft 6.

[0031] The clamping assembly includes two mounting cylinders 14, which are located on the front and rear sides of the rotating ring 13, respectively, and are connected to the front and rear sides of the mounting frame 11. A spring 15 and a slide rod 16 are provided inside the mounting cylinder 14. The slide rod 16 is slidably connected to the mounting cylinder 14 and guided by the mounting cylinder 14. The slide rod 16 is connected to the spring 15. The spring 15 allows the slide rod 16 to drive the subsequent anti-slip pad 18 away from the rotating ring 13 when it is not subjected to external force. A mounting plate 17 is provided on the slide rod 16 opposite to the rotating ring 13, and an arc-shaped anti-slip pad 18 is provided on the mounting plate 17 to facilitate clamping the rotating ring 13.

[0032] The right end of the rotating ring 13 is provided with a uniform circumferential groove 19, and the groove 19 is opposite to the anti-slip pad 18. The groove 19 has a semi-circular structure, which makes it easier for the anti-slip pad 18 to enter the groove 19 so as to stably clamp the rotating ring 13.

[0033] The second implementation method differs from the first implementation method in that: both ends of the left end of the rotating drum 5 are provided with protrusions, and the bolts 10 are connected to the protrusions, which facilitates the installation of the bolts 10.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] In use, remove bolt 10, move the rotating shaft 6 so that the chuck 7, tap 8, swivel 13, bearing 12 and mounting bracket 11 all move to the left. Stop when they are in the appropriate position. Then press the mounting plates 17 on both sides toward the opposite side so that the anti-slip pad 18 fixes the swivel 13. At this time, the slide rod 16 is guided by the mounting cylinder 14 so that the rotating shaft 6 and the rotating cylinder 5 will not rotate, thus making it easy to install bolt 10. After installation, the user can hold the tapping drill 1 on the outside and make the tap 8 enter the narrow space to complete the tapping. When tapping, the left end of the rotating shaft 6 can also be supported by the bearing 12.
