Technical Field

[0001] This application relates to the field of tapping machine equipment technology, and in particular to an adjustable tapping mechanism for a tapping machine. Background Technology

[0002] In the field of machining and manufacturing, tapping is a common and important process used to machine internal threads on workpieces;

[0003] Traditional tapping mechanisms often require replacing the entire tapping head assembly when faced with different thread specifications, which is cumbersome and time-consuming. For example, when switching from machining one type of thread pitch to another, it is usually necessary to disassemble the original tapping head and install a new, compatible tapping head. This not only increases the labor intensity of workers but also significantly reduces processing efficiency. Therefore, an adjustable tapping mechanism for tapping machines is proposed to solve the above problems. Utility Model Content

[0004] To address the problem that traditional tapping mechanisms often require replacing the entire tapping head assembly when facing different thread specifications, which is cumbersome and time-consuming, this application provides an adjustable tapping mechanism for tapping machines.

[0005] The adjustable tapping mechanism for a tapping machine provided in this application adopts the following technical solution:

A mounting cylinder is fixedly connected to the bottom outer wall of the connecting flange. A tapping head is inserted into the inner wall of the mounting cylinder. A quick-release mechanism for easy replacement of the tapping head is installed on the outer wall of the mounting cylinder.

[0007] The quick-release mechanism consists of two sets, symmetrically distributed on the outer wall of the mounting cylinder. Each set includes two limiting frames symmetrically fixedly connected to the outer wall of the mounting cylinder. A movable block is slidably connected to the outer wall of each limiting frame. Two springs are also sleeved on the outer wall of each limiting frame. The springs are located between the movable block and the limiting frame. A locking block is fixedly connected to the outer wall of the movable block facing the mounting cylinder. Two locking slots are symmetrically opened on the outer wall of the inner side of the mounting cylinder. The end of the locking block away from the limiting frame passes through the mounting cylinder and engages with the locking slot. The end of the locking block inside the mounting cylinder is set at an angle, with the angle facing downwards.

[0008] The outer wall of the mounting cylinder is also equipped with a linkage mechanism for driving the two quick-release mechanisms to unlock synchronously.

[0009] Preferably, the linkage mechanism includes a rotating shaft rotatably connected to the outer wall of the middle of the mounting cylinder, a drive arm fixedly connected to the outer wall of the rotating shaft, and connecting rods rotatably connected to both ends of the drive arm.

[0010] Preferably, the linkage mechanism further includes a push rod fixedly connected to the outer side wall of the middle section of the two movable blocks, the end of the linkage away from the drive arm is rotatably connected to the push rod, and a knob is fixedly connected to the end of the rotating shaft away from the mounting cylinder.

[0011] Preferably, the inner wall of the mounting cylinder is fixedly connected to two positioning blocks, which are arranged perpendicularly to two locking blocks. The outer wall of the tapping head is symmetrically provided with two positioning grooves, which are adapted to and inserted into the two positioning blocks.

[0012] Preferably, the movable frame is mounted on the outer wall of the frame via a translation component, which drives the movable frame to move on the outer wall of the frame.

[0024] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0025] This application discloses an adjustable tapping mechanism for a tapping machine. (Refer to...) Figure 1-7 An adjustable tapping mechanism for a tapping machine includes a frame 1, a translation component 2, a moving frame 3, a lifting component 4, a mounting frame 5, a drive motor 6, and a connecting flange 7. The moving frame 3 is mounted on the outer wall of the frame 1 via the translation component 2, which drives the moving frame 3 to move on the outer wall of the frame 1. The mounting frame 5 is mounted on the outer wall of the moving frame 3 via the lifting component 4, which drives the mounting frame 5 to rise and fall on the outer wall of the moving frame 3. The drive motor 6 is fixedly mounted on the inner wall of the mounting frame 5. The end of the output shaft of the drive motor 6 passes through the mounting frame 5 and is fixedly connected to the connecting flange 7. An mounting cylinder 8 is fixedly connected to the bottom outer wall of the connecting flange 7. A tapping head 9 is inserted into the inner wall of the mounting cylinder 8. A quick-release mechanism for easy replacement of the tapping head 9 is installed on the outer wall of the mounting cylinder 8.

[0026] Reference Figure 1 and Figure 2 The connecting flange 7 can be fixedly connected to the output shaft of the drive motor 6 by screws. Both the translation component 2 and the lifting component 4 adopt a screw drive structure to drive the translation of the moving frame 3 and the lifting of the mounting frame 5. The screw drive structure is a known technology and will not be described in detail.

[0027] The quick-release mechanism consists of two sets, symmetrically distributed on the outer wall of the mounting cylinder 8. Each set includes two limiting frames 10 symmetrically fixedly connected to the outer wall of the mounting cylinder 8. A movable block 11 is slidably connected to the outer wall of the limiting frame 10. Two springs 12 are also sleeved on the outer wall of the limiting frame 10. The springs 12 are located between the movable block 11 and the limiting frame 10. A locking block 13 is fixedly connected to the outer wall of the movable block 11 facing the mounting cylinder 8. Two slots 14 are symmetrically opened on the outer wall of the tapping head 9 inside the mounting cylinder 8. The end of the locking block 13 away from the limiting frame 10 passes through the mounting cylinder 8 and engages with the slot 14. The end of the locking block 13 inside the mounting cylinder 8 is set at an angle, with the angle facing downward.

[0028] Reference Figure 4The limiting frame 10 includes two limiting rods and a limiting plate, which are U-shaped. The movable block 11 is slidably connected to the two limiting rods, while the limiting plate can prevent the movable block 11 from disengaging from the two limiting rods. Two springs 12 are sleeved on the limiting frame 10, with one end abutting against the movable block 11 and the other end abutting against the limiting plate.

[0029] The outer wall of the mounting cylinder 8 is also equipped with a linkage mechanism for driving the two quick-release mechanisms to unlock synchronously. The linkage mechanism includes a rotating shaft 16 rotatably connected to the middle outer wall of the mounting cylinder 8. A drive arm 17 is fixedly connected to the outer wall of the rotating shaft 16. Connecting rods 18 are rotatably connected to both ends of the drive arm 17. The linkage mechanism also includes a push rod 15 fixedly connected to the outer wall of the middle section of the two movable blocks 11. The end of the connecting rod 18 away from the drive arm 17 is rotatably connected to the push rod 15. A knob 19 is fixedly connected to the end of the rotating shaft 16 away from the mounting cylinder 8.

[0030] Reference Figure 6 and Figure 7 Two positioning blocks 20 are fixedly connected to the inner wall of the positioning groove 21. The two positioning blocks 20 are perpendicularly intersected with the two locking blocks 13. Two positioning grooves 21 are symmetrically opened on the outer wall of the tapping head 9. The two positioning grooves 21 are adapted to the two positioning blocks 20 for insertion. When the tapping head 9 is inserted into the mounting cylinder 8, the positioning blocks 20 facilitate the insertion of the positioning grooves 21, which can play a positioning role for the tapping head 9 and prevent the tapping head 9 from shaking or rotating inside the mounting cylinder 8.

[0031] The implementation principle of an adjustable tapping mechanism for a tapping machine according to an embodiment of this application is as follows: In use, the translation component 2 drives the moving frame 3 to move, adjusting the left and right positions of the tapping head 9; the lifting component 4 drives the mounting frame 5 to lift, adjusting the height position of the tapping head 9; and the output shaft of the drive motor 6 can drive the tapping head 9 to rotate for tapping.

[0032] When it is necessary to change the tapping head 9 with a different pitch, the knob 19 can be turned via the linkage mechanism. The knob 19 drives the rotating shaft 16 to rotate, which in turn drives the drive arm 17 to rotate. When the drive arm 17 rotates clockwise, its two ends push the two connecting rods 18 to move outward. The rotation of the two connecting rods 18 pushes the two movable blocks 11 to move away from each other on the outer walls of the two limit brackets 10 via the push rod 15. At this time, the two movable blocks 11 move away from each other, which causes the two locking blocks 13 to disengage from the locking slots 14, releasing the tapping head 9 from the lock. Under the action of gravity, the tapping head 9 quickly disengages from the mounting bracket. Inside the mounting cylinder 8, the operator can catch the tapping head 9. After the tapping head 9 is disassembled, the knob 19 is released. As the two movable blocks 11 move in opposite directions, they will compress the spring 12. The spring 12 deforms and generates elastic force. When the drive arm 17 is no longer subjected to the rotational force of the knob 19, the two movable blocks 11 will reset under the elastic force of the spring 12. The movable blocks 11 push the connecting rod 18 inward through the push rod 15. The two connecting rods 18 push the drive arm 17 inward to rotate, so that the drive arm 17 resets and rotates counterclockwise. At this time, the two locking blocks 13 will re-enter the mounting cylinder 8 to re-lock the tapping head 9.

[0033] When the tapping head 9 is installed, the positioning block 20 on the outer wall of the tapping head 9 is aligned and inserted with the positioning groove 21 on the inner wall of the mounting cylinder 8. The two slots 14 on the outer wall of the tapping head 9 automatically correspond to the two locking blocks 13. When the tapping head 9 enters the mounting cylinder 8, its outer wall presses against the downward inclined surface of the two locking blocks 13. The locking blocks 13 can be easily pushed outward through the inclined surface, and the two locking blocks 13 are squeezed out of the mounting cylinder 8. The locking blocks 13 push the movable block 11 to slide outward on the outer wall of the limit bracket 10. Similarly, when the tapping head 9 is pressed against the inner wall of the top of the mounting cylinder 8, the two slots 14 on the outer wall of the tapping head 9 correspond to the two locking blocks 13. The outer wall of the tapping head 9 will no longer press the locking blocks 13, and the moving block 11 will reset under the elastic force of the spring 12. The moving block 11 pushes the locking blocks 13 back into the mounting cylinder 8 and engages with the slots 14, thereby automatically locking the tapping head 9 and completing the installation.

[0034] In summary, the overall replacement process of the tapping head 9 is as follows: by rotating the knob 19 in the linkage mechanism, the locking of the tapping head 9 can be quickly released. During installation, the tapping head 9 with the new pitch is directly inserted back into the mounting sleeve 8, and the quick-release mechanism automatically locks the tapping head 9. The overall operation is simple and convenient, and easy to use.
