[0027] 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.

[0028] Example

[0029] Please see Figures 1-5 This utility model provides the following technical solution: an automatic tapping machine with accurate positioning, including a tapping machine body 1, a placement platform 2 disposed on the tapping machine body 1 below the tapping drill bit, a pair of rectangular elongated holes 5 formed on the placement platform 2, and a tapping hole 26 formed on the placement platform 2; further comprising:

[0030] The clamping mechanism 4 includes a support plate 3 disposed at the bottom of the placement table 2, a forward and reverse threaded rod 8 rotatably disposed on the support plate 3, and a servo motor 7 for driving the forward and reverse threaded rod 8 is installed on one side of the support plate 3. The servo motor 7 shares a power line with the tapping machine body 1, and a control switch for starting, stopping, rotating forward and reversing the servo motor 7 is provided on the tapping machine body 1. The clamping mechanism 4 is used to limit and fix the tapping parts. The servo motor 7 drives the forward and reverse threaded rod 8 to rotate clockwise or counterclockwise through forward and reverse rotation.

[0031] The material blocking mechanism 6 is mounted on the clamping mechanism 4 and located below the tapping drill bit of the tapping machine body 1. It is used to block the debris generated during tapping.

[0032] Preferably, by Figure 2 and Figure 3 As shown, in this embodiment, a pair of movable plates 9 are threadedly connected to the positive and negative threaded rods 8. The two movable plates 9 can move closer to each other or further away. A pair of connecting upright plates 10 are provided on the top of the movable plates 9. The connecting upright plates 10 pass through the rectangular elongated hole 5.

[0033] A fixing plate 13 is fixed on the connecting plate 10. The fixing plate 13 is located above the placement platform 2. Positioning plates 14 are provided on the opposite sides of the two fixing plates 13. Multiple anti-slip stripes 15 are provided on the positioning plates 14.

[0034] In use, place the nut to be tapped on the placement table 2, so that its tapping position is above the tapping hole 26, which can be vertically aligned with the tapping drill bit on the tapping machine body 1. Then, start the servo motor 7 in forward rotation mode. The forward and reverse thread screws 8 drive the two fixing plates 13 to move closer to each other, thereby forcing the two positioning plates 14 to gradually approach and squeeze the nut to be tapped. After fixing, start the tapping machine body 1 to start the tapping work.

[0035] Preferably, by Figure 2 As shown, in this embodiment, a guide rod 11 is threadedly connected to the support plate 3. A knob 12 is fixed at one end of the guide rod 11. The guide rod 11 is slidably connected to the moving plate 9. The moving plate 9 is driven by the positive and negative threaded rods 8 to slide on the two guide rods 11. The guide rods 11 can prevent the moving plate 9 from rotating, so that it moves stably and improves stability.

[0036] Preferably, by Figure 3 and Figure 5 As shown, in this embodiment, the material blocking mechanism 6 includes a mounting plate 16 fixed on the fixing plate 13, and an L-shaped plate 17 is fixed on the mounting plate 16.

[0037] A pair of slide rods 18 are slidably connected to the L-shaped plate 17. A dust baffle 23 is provided at one end of the slide rod 18, and a second knob 19 is provided at the other end. Both dust baffles 23 are provided with anti-blocking holes 24. The anti-blocking holes 24 are located directly above the tapping holes 26. The tapping drill bit of the tapping machine body 1 can pass through the anti-blocking holes 24. Adhesive plates 25 are fixed to the adjacent ends of the two dust baffles 23.

[0038] The dust baffle 23 is fixed with a fixing nut 20 that matches the slide rod 18. The slide rod 18 is threadedly connected to the fixing nut 20. After long-term use, the slide rod 18 can be removed by turning it counterclockwise to facilitate the replacement of the dust baffle 23 or the slide rod 18.

[0039] Preferably, by Figure 2 and Figure 3 As shown, in this embodiment, a fixing iron plate 21 is fixed on the fixing nut 20, and a return spring 22 is sleeved on the outside of the slide rod 18. The two ends of the return spring 22 abut against the fixing iron plate 21 and the L-shaped plate 17 respectively. After long-term use, the slide rod 18 can be disassembled by turning counterclockwise to replace the return spring 22.

[0040] When the two dust baffles 23 approach each other and connect, the squeezing force will cause the slide bar 18 to slide on the L-shaped plate 17, and the return spring 22 will be compressed, which will not affect the two positioning plates 14 below from continuing to approach each other, thus making it suitable for more sizes of tapping parts, with a wide positioning range and high practicality.

[0041] Components not described in detail in this article are existing technologies.

[0042] The working principle and usage process of this utility model are as follows: When in use, place the nut to be tapped on the placement table 2, so that its tapping position is above the tapping hole 26, which can be vertically aligned with the tapping drill bit on the tapping machine body 1. Then, start the servo motor 7 in forward rotation mode. The forward and reverse thread screws 8 drive the two fixing plates 13 to move closer to each other, thereby forcing the two positioning plates 14 to gradually move closer and squeeze the nut to be tapped. At the same time, the two dust baffles 23 move closer to each other and connect. The squeezing force will cause the slide rod 18 to slide on the L-shaped plate 17, and the return spring 22 will be compressed, which will not affect the two positioning plates 14 below from moving closer to each other. Thus, it is suitable for tapping parts of more sizes, has a wide positioning range, and is highly practical. After fixing, start the tapping machine body 1 to start the tapping work.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
