The transmission mechanism includes a bellows, a motor, a first gear, a movable rod, a second gear, and a U-shaped plate. The motor is fixedly connected to the back end of the inner wall of the bellows, and the first gear is fixedly connected to the output end of the motor. The movable rod is movably connected to the bottom of the inner wall of the bellows via a rotating shaft. This invention utilizes a starting motor to drive the first gear to rotate, which in turn drives the second gear, the movable rod, and the U-shaped plate to rotate. The rotation of the U-shaped plate causes the rotating sleeve to rotate, simultaneously driving the connecting rod to rotate. The rotation of the connecting rod causes the solid rod to rotate via the rotating shaft, simultaneously causing a rectangular block to move left and right on a first sliding groove via the rotating shaft. The left and right movement of the rectangular block causes the support plate and the fan to move accordingly, thus improving the working efficiency of the tapping machine.

[0004] When using the aforementioned tapping machine for bolt processing, the workpiece needs to be manually removed after processing, which affects work efficiency, reduces production efficiency, and increases the labor intensity of manual labor. Utility Model Content

[0005] This utility model proposes a tapping machine for bolt processing, which solves the problem in related technologies where the workpiece needs to be manually removed after processing, thus affecting work efficiency, reducing production efficiency and increasing the labor intensity of manual labor.

[0006] The technical solution of this utility model is as follows: a tapping machine for bolt processing includes a device body, a feeding component rotatably connected to the bottom of the device body, and a clamping component fixed to the top of the device body;

[0007] The feeding assembly includes a base, a drive gear rotatably connected to the center of the base, a processing table rotatably connected to the top of the drive gear, a driven gear meshing with the side of the drive gear, a support column fixed to the top of the driven gear, a drive bevel gear fixed to the top of the support column, a driven bevel gear meshing with the side of the drive bevel gear, a push rod threadedly connected to the side of the driven bevel gear, and a push plate fixed to the side of the push rod.

[0008] Preferably, a feeding trough is fixed to the side of the base, and a collection box is fixed to the other end of the feeding trough.

[0009] Preferably, the processing table has an annular groove inside, and several sets of driven bevel gears are rotatably connected inside the processing table, with the driven bevel gears evenly distributed in the processing table.

[0010] Preferably, a threaded post is fixed to the driven bevel gear near the push rod, and the threaded post is threadedly connected to the push rod.

[0011] Preferably, the processing table has several sets of placement slots, and the number of driven bevel gears is equal to the number of placement slots.

[0012] Preferably, the clamping assembly includes a rotating column, a mounting shell is fixed to the bottom of the rotating column, a rotating ring is rotatably connected to the mounting shell, a connecting column is rotatably connected to the inner side of the rotating ring, a connecting shaft is rotatably connected to the other end of the connecting column, and a clamping plate is rotatably connected to the other end of the connecting shaft.

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

[0025] Example 1

[0026] like Figures 1-3 As shown, this embodiment proposes a tapping machine for bolt processing, including a device body 1, a feeding assembly 2 rotatably connected to the bottom of the device body 1, and a clamping assembly 3 fixed to the top of the device body 1.

[0027] The unloading assembly 2 includes a base 21, a drive gear 22 rotatably connected to the middle of the base 21, a processing table 23 rotatably connected to the top of the drive gear 22, a driven gear 24 meshing with the side of the drive gear 22, a support column 25 fixed to the top of the driven gear 24, a drive bevel gear 26 fixed to the top of the support column 25, a driven bevel gear 28 meshing with the side of the drive bevel gear 26, a push rod 29 threadedly connected to the side of the driven bevel gear 28, and a push plate 210 fixed to the side of the push rod 29.

[0028] A feeding trough 212 is fixed to the side of the base 21, and a collection box 213 is fixed to the other end of the feeding trough 212. The feeding trough 212 and the collection box 213 can collect the bolts pushed out from the processing table 23.

[0029] The machining table 23 has an annular groove 27 inside, and several sets of driven bevel gears 28 are rotatably connected inside the machining table 23. The driven bevel gears 28 are evenly distributed in the annular groove 27 in the machining table 23 so that the driven bevel gear 28 where the bolt is located after machining rotates to the side of the driving bevel gear 26, and the bolt is pushed out by the rotation.

[0030] A threaded post 211 is fixed on the side of the driven bevel gear 28 near the push rod 29. The threaded post 211 is threadedly connected to the push rod 29. The threaded post 211 rotates in the push rod 29, so that when the push rod 29 moves, it drives the push plate 210 to move.

[0031] The processing table 23 has several sets of placement slots. The number of driven bevel gears 28 is equal to the number of placement slots. Multiple bolts to be processed can be placed in the several sets of placement slots to improve processing efficiency.

[0032] In this embodiment, the bolt is placed in the placement slot in the processing table 23. When the processing table 23 is rotated clockwise, it is first processed by the clamping assembly 3. After processing, the driven bevel gear 28 inside the placement slot rotates and moves to the side of the driving bevel gear 26, and meshes with the driving bevel gear 26. The driving bevel gear 26 meshes with the driven bevel gear 28 on the side, and the threaded post 211 on the side of the driven bevel gear 28 rotates in the push rod 29. The push rod 29 drives the push plate 210 to move outward, and pushes the processed bolt into the unloading slot 212 and collects it in the collection box 213. This replaces manual unloading and improves production efficiency.

[0033] Example 2

[0034] like Figures 4-5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes a clamping assembly 3 including a rotating column 31, a mounting shell 32 fixed at the bottom of the rotating column 31, a rotating ring 33 rotatably connected in the mounting shell 32, a connecting column 37 rotatably connected inside the rotating ring 33, a connecting shaft 39 rotatably connected at the other end of the connecting column 37, and a clamping plate 310 rotatably connected at the other end of the connecting shaft 39.

[0035] A spring telescopic rod 34 is fixed to the top of the rotating column 31, and an outer retaining ring 35 is fixed to the bottom of the spring telescopic rod 34. An inner retaining ring 36 is provided inside the outer retaining ring 35, and the spring telescopic rod 34 is fixed to the top of the inner retaining ring 36. Both the outer retaining ring 35 and the inner retaining ring 36 have arc-shaped grooves 312. The inner retaining ring 36 and the outer retaining ring 35 raise the spring telescopic rod 34, so that the mounting shell 32 can adapt to taps of different diameters and can be replaced according to processing needs.

[0036] The mounting housing 32 has a rotating groove 311 inside, and a rotating shaft 38 is fixed in the rotating groove 311. The connecting post 37 is rotatably connected to the rotating shaft 38. The lengths of the connecting posts 37 on both sides of the rotating shaft 38 are different. The connecting post 37 on the side closer to the rotating ring 33 is shorter, and the connecting post 37 on the side closer to the clamping plate 310 is longer.

[0037] In this embodiment, when it is necessary to change the taps of different diameters according to different processing requirements, the taps are installed inward from the bottom of the mounting shell 32. At the same time, the top of the tap abuts against the inner retaining ring 36 and moves inward through the spring telescopic rod 34. After the tap enters the interior of the mounting shell 32, the rotating ring 33 is rotated, causing the connecting post 37 on the inner side of the rotating ring 33 to rotate through the rotating shaft 38. This causes the clamping plate 310, which is rotatably connected through the connecting shaft 39, to move closer to the outside of the tap. The rotating ring 33 causes the clamping plate 310 to clamp the tap tightly. At this time, the inner side of the clamping plate 310 is in contact with the outer side of the tap, and one end of the outer side of the clamping plate 310 is in contact with the inner wall of the outer retaining ring 35, thereby fixing the clamping plate 310 and making the clamping of the tap more stable.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
