Description

Technical Field

[0001] This utility model relates to the field of tapping technology, specifically to a tapping mechanism and a tapping machine. Background Technology

[0002] A tapping machine is a mechanical processing device that processes internal threads, screws, or threads on the inner surface of holes in various parts such as machine housings, equipment end faces, nuts, and flanges with different specifications of through holes or blind holes.

[0003] A search revealed Chinese Patent Publication No. CN220739709U, which discloses a tapping machine with an adjustable tapping mechanism. The machine includes a worktable, a column fixedly mounted on the top of the worktable, a horizontal plate slidably mounted on the side of the column via a lifting assembly, a support frame fixedly mounted at the bottom of the horizontal plate, a rotating shaft rotatably mounted at the bottom of the support frame, and an annular plate fixedly connected to the outer side of the rotating shaft via a connecting rod. Multiple tapping components are fixedly mounted on the circumference of the annular plate, and a third motor for driving the rotating shaft is fixedly mounted on the support frame. A placement slot is provided on the top of the worktable. This application allows for the adjustment of different sized tapping components to the lower side for tapping operations by activating the third motor, which drives the rotating shaft to rotate, which in turn drives the annular plate. This satisfies various tapping needs and improves the practicality of the device.

[0004] However, in the above technical solution, the tapping operation on the workpiece is performed by simply rotating the ring plate to move different taps. However, when this patent is used, the multiple motors and multiple taps correspond to each other, which increases the cost. The multiple taps are located on the outside of the ring plate and will move with the movement of the ring plate. The taps are relatively sharp, which makes it easy for workers to accidentally touch and injure them when they are not in use. Utility Model Content

The tapping assembly includes a power assembly and a replacement assembly, which are arranged in parallel and both are connected to the frame. When the power assembly is in use, it moves towards the worktable and provides tapping power. When the replacement assembly is in use, it rotates at a certain angle to connect taps of different sizes to the power assembly. A protective assembly is connected to the frame. When the protective assembly is in use, it is fitted over the replacement assembly to form a protective space.

[0007] Preferably, the power assembly includes a telescopic device connected to the frame, with the telescopic end of the telescopic device passing through the frame and connected to a support plate; a first drive device connected to the support plate; a rotating shaft, one end of which is connected to the output end of the first drive device; and a connector connected to the rotating shaft.

[0008] Preferably, the replacement component includes a second drive device connected to the frame; a support shaft passing through the frame and connected to the output end of the second drive device; a support plate connected to the end of the support shaft away from the second drive device, the support plate having multiple through holes; a connecting shaft having the same center as the through holes on the support plate, one end of the connecting shaft having a connecting groove that mates with a connector, the other end of the connecting shaft being used to connect a tap; and a reset component connected to the support plate; in the use state, the reset component drives the connecting shaft to move back to the initial position.

[0009] Preferably, the reset assembly includes a movable plate corresponding to the number of connecting shafts, the movable plate having the same center as the through hole, and the movable plate being disposed below the support plate; and an elastic element, the two ends of which are respectively connected to the support plate and the movable plate.

[0010] Preferably, the protective assembly includes a fixing rod connected to the frame and a protective cover detachably connected to the fixing rod.

[0011] Preferably, multiple detachable cleaning brushes are connected inside the protective cover.

[0012] Preferably, the cleaning brush is connected to a dovetail block, which is slidably connected to a dovetail groove on the inner wall of the protective cover.

[0013] A tapping machine, comprising any one of the tapping mechanisms.

[0014] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0025] The replacement assembly includes a second drive device 8, a support shaft 9, a support plate 10, a connecting shaft 11, and a reset assembly. The second drive device 8 is connected to the upper surface of the frame 2; the second drive device 8 is a motor; the support shaft 9 passes through a through hole in the frame 2 and connects to the output end of the second drive device 8; the support plate 10 is connected to the end of the support shaft 9 away from the second drive device 8; the support plate 10 has multiple through holes distributed circumferentially with the central axis of the support shaft 9 as the center; the connecting shaft 11 has the same center as the through holes on the support plate 10; one end of the connecting shaft 11 has a connecting groove 12 that mates with the connector 7; the other end of the connecting shaft 11 is used to connect a tap; the reset assembly is connected to the support plate 10; when the reset assembly is in use, the reset assembly drives the connecting shaft 11 to move back to the initial position.

The two ends of the elastic element 14 are connected to the support plate 10 and the movable plate 13, respectively. The elastic element 14 may be selected from, but is not limited to, springs.

[0027] Example 3

[0028] like Figure 2 , Figure 4 As shown, the present invention proposes a tapping mechanism and tapping machine. Compared with Embodiment 2, this embodiment describes the detailed structure of the protective component. The protective component includes a fixing rod 15 and a protective cover 16.

[0031] A tapping machine comprising the tapping mechanism of any one of claims 1-7.

[0032] In summary, when using this utility model, the operator places the fixture and the workpiece to be processed on the workbench, selects the tap according to the required tapping diameter, and drives the support shaft 9 to rotate by activating the second drive device 8. The support plate 10 on the support shaft 9 rotates, causing multiple taps to rotate around the support shaft 9. When the appropriate tap rotates to below the rotating shaft 6 and the connecting head 7, the second drive device 8 stops operating, and the telescopic device 3 is activated to move the support plate 4 and the first drive device 5. The rotating shaft 6 and the connecting head 7 move downwards, and the connecting shaft 11 and the tap rotate through the mutual engagement of the connecting head 7 and the connecting groove 12 on the connecting shaft 11. As the telescopic device 3 continues to move downwards... The tap moves to machine threaded holes on the workpiece. When the telescopic device 3 moves downward, it stretches the elastic element 14 through the connector 7, thereby moving the moving plate 13 and the connecting shaft 11 closer to the workpiece to be machined. When the machining is completed, the rotating shaft 6 and the connector 7 flip and rise. The elastic element 14 elastically drives the moving plate 13 and the connecting shaft 11 to rise synchronously with the connector 7 and return to their original positions. When selecting different taps, the rotation of the support plate 10 will drive the connecting shaft 11 to move inside the protective cover 16. During this process, the bristles of the cleaning brush 17 connected to the inner walls on both sides of the protective cover 16 come into contact with the surface of the tap to prevent residual metal debris on the surface of the tap from affecting subsequent use.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
