This utility model, through the cooperative operation between the rotating platform, the driving component, the internal column, and the clamping frame, facilitates the clamping of nuts while enabling rapid processing, thus avoiding excessively slow clamping and delays in processing results.

[0004] Although the aforementioned patent can quickly clamp the nuts and improve processing efficiency, each nut to be processed needs to be clamped, which reduces processing efficiency. Furthermore, the nuts cannot be automatically discharged after tapping, which further reduces tapping efficiency. Therefore, a carbon nut inner hole tapping device is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a carbon nut inner hole tapping device that can overcome or at least partially solve the above problems.

The nut is placed in the slide, and the tap is rotated and moved downward to tap the nut, and then reversed and moved upward to disengage from the nut; after tapping, the two connecting shafts rotate relative to each other, and the lever pushes the nut in the slide to disengage from the limiting seat.

[0007] Preferably, a first gear is rotatably connected to the bottom of the limiting seat near one of the connecting shafts, and a second gear is installed on the connecting shaft near the first gear. The first gear and the second gear mesh with each other, and the first gear is connected to the other connecting shaft by a synchronous belt. An avoidance groove is provided on the limiting seat located on the side wall of the slide, and the lever is located in the avoidance groove.

[0008] Furthermore, the bottom of the limiting seat is equipped with a bottom frame, and a connecting column is fixedly connected to the bottom frame; it also includes a three-jaw chuck, and the connecting column is connected to the three-jaw chuck.

[0009] Preferably, a bracket is installed on the limiting seat, and a first motor is installed on the bracket. The first motor is connected to one of the connecting shafts.

[0010] Furthermore, the limiting seat is provided with a track groove, which includes a recessed channel and a flat channel. The upper surface of the recessed channel is horizontal with the slide rail, and the bottom surface of the flat channel is horizontal with the surface of the slide rail. A scraper is slidably connected in the track groove, which is used to drive the scraper to slide away from the nut when the lever pushes the nut away from the limiting seat, so as to clean the debris on the surface of the slide rail. The upper surface of the scraper is horizontal with the surface of the slide rail.

[0011] Preferably, a sector gear is installed on both connecting shafts, a fixed frame is installed on the limiting seat, a guide rod is installed on the fixed frame, a rack is slidably connected to the guide rod, a second spring is connected between the rack and the fixed frame, a connecting frame is fixedly connected to one end of the rack, and a T-shaped rod is fixedly connected to both ends of the scraper rod.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0025] Example: Refer to Figures 1-6 A carbon nut inner hole tapping device includes a limiting seat 1, and further includes: a slide 11, formed on the limiting seat 1, for circumferentially limiting the nut 10; a stop rod 5, installed on the limiting seat 1, for limiting the upper part of the nut 10; and connecting shafts 12, symmetrically rotatably arranged on both sides of the limiting seat 1, with levers 121 fixedly connected to each of the two connecting shafts 12. The nut 10 is placed in the slide 11, and the tap 43 rotates and moves downward to tap the nut 10, and then reverses and moves upward to disengage from the nut 10; after tapping, the two connecting shafts 12 rotate relative to each other, and the levers 121 push the nut 10 in the slide 11 to disengage from the limiting seat 1.

[0026] A first gear 16 is rotatably connected to the bottom of a limiting seat 1 near one of the connecting shafts 12. A second gear 161 is installed on the connecting shaft 12 near the first gear 16. The first gear 16 and the second gear 161 mesh with each other. The first gear 16 is connected to the other connecting shaft 12 via a synchronous belt 162. A clearance groove 123 is provided on the limiting seat 1 located on the side wall of the slide 11, and the lever 121 is located in the clearance groove 123.

[0027] The bottom of the limiting seat 1 is equipped with a bottom frame 14, and a connecting column 141 is fixedly connected to the bottom frame 14; it also includes a three-jaw chuck 15, and the connecting column 141 is connected to the three-jaw chuck 15, which facilitates the installation of the limiting seat 1.

[0028] A bracket 131 is installed on the limit seat 1, and a first motor 13 is installed on the bracket 131. The first motor 13 is connected to one of the connecting shafts 12.

[0029] The limiting seat 1 has a track groove 2, which includes a sinking channel 21 and a flat channel 22. The upper surface of the sinking channel 21 is horizontal with the slide rail 11, and the bottom surface of the flat channel 22 is horizontal with the surface of the slide rail 11. A scraper 23 is slidably connected in the track groove 2. When the lever 121 pushes the nut 10 away from the limiting seat 1, the scraper 23 is driven to slide away from the nut 10 to clean the debris on the surface of the slide rail 11. The upper surface of the scraper 23 is horizontal with the surface of the slide rail 11.

[0030] Both connecting shafts 12 are equipped with sector gears 122. A fixed frame 34 is installed on the limiting seat 1. A guide rod 35 is installed on the fixed frame 34. A rack 3 is slidably connected to the guide rod 35. A second spring 36 is connected between the rack 3 and the fixed frame 34. A connecting frame 31 is fixedly connected to one end of the rack 3. T-shaped rods 32 are fixedly connected to both ends of the scraper 23. The T-shaped rods 32 are slidably connected to the connecting frame 31. The connecting frame 31 and the T-shaped rods 32 are connected by a first spring 33.

[0031] The limiting seat 1 has a groove 20.

[0032] It also includes a lead screw drive 4, on which a second motor 41 is mounted, and a rotating shaft 42 is rotatably connected to the second motor 41, with a tap 43 mounted on the rotating shaft 42.

[0033] In use, the nut 10 is manually pushed from one end of the slide 11 to below the tap 43 and below the stop bar 5. The tap 43 is driven to move downward by the screw drive 4, and the second motor 41 drives the tap 43 to rotate. Therefore, when the tap 43 moves downward while rotating, it can automatically correct the nut 10 when it contacts the inner hole of the nut 10, making the nut 10 and the tap 43 coaxial, thereby realizing the tapping of the inner hole of the nut 10. The slide 11 can limit the nut 10 to prevent the nut 10 from rotating during the tapping process. Therefore, compared with the prior art, there is no need to clamp the nut 10. The downward rotating tap 43 can automatically position and tap the nut 10, effectively improving the tapping efficiency.

[0034] After tapping is completed, tap 43 reverses and moves upward. Nut 10 is blocked by stop bar 5 and will not move upward. Then the first motor 13 drives the two connecting shafts 12 to rotate relative to each other. The lever 121 pushes nut 10, causing nut 10 to disengage from slide 11, thus completing the automatic unloading after tapping.

[0035] Preferably, a sensor is installed on the limiting seat 1, and a contact plate is installed on the slide of the lead screw drive 4. When the tap 43 moves upward, the contact plate moves upward synchronously and moves away from the sensor, and the first motor 13 starts to rotate one revolution.

[0036] When the connecting shaft 12 rotates, it will drive the sector gear 122 to rotate. When rotating, it will mesh and drive the rack 3 to slide on the guide rod 35, and drive the scraper 23 to slide in the track groove 2 through the connecting frame 31.

[0037] Since the scraper rod 23 is initially located in the recessed channel 21 of the track groove 2, when the connecting frame 31 pushes the scraper rod 23 to move, the scraper rod 23 will move upward and squeeze the first spring 33, causing the scraper rod 23 to move to the flat channel 22 and stick to the surface of the slide 11. This pushes the debris generated by tapping in the slide 11 away from the slide 11 and falls out of the slot 20, thereby making the surface of the slide 11 clean and preventing the nuts 10 placed in the slide 11 from becoming uneven due to debris, which would cause the tapping to become skewed.

[0038] On the other side, the slide 11 will automatically clean the debris on its surface when the nut 10 is pushed away.

[0039] Because of the use of sector gear 122, when sector gear 122 rotates and pushes rack 3 to move, after the teeth on sector gear 122 disengage from rack 3, rack 3 will be pushed back quickly by second spring 36, and then automatically complete the reset after pushing scraper 23 to clean slide 11.

[0040] Therefore, this utility model limits the nut 10 by using the slide rail 11, so that the rotating and downward moving tap 43 automatically positions and taps the nut 10, effectively improving the tapping efficiency. After tapping is completed, the first motor 13 drives the two connecting shafts 12 to rotate relative to each other, and pushes the nut 10 through the lever 121, so that the nut 10 is disengaged from the slide rail 11, thereby completing the automatic unloading after tapping. When the lever 121 pushes the nut 10, it can also simultaneously make the scraper 23 slide on the surface of the slide rail 11 to clean the surface of the slide rail 11, avoiding the nut 10 placed in the slide rail 11 from being uneven due to debris, which would cause the tapping to be skewed, thereby effectively improving the tapping efficiency and quality.

[0041] Secondly, this device can also tap nuts made of other materials, such as carbon steel.

[0042] Furthermore, a protective cover can be installed to enclose the rotating structure in this device, preventing it from becoming entangled with external objects.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
