The top of the support platform 1 is fixedly connected to the base plate 11, the top of the base plate 11 is slidably connected to the protective shell 13, the inside of the protective shell 13 is fixedly connected to the thread rolling wheel 12, the top of the base plate 11 is fixedly connected to the water tank 14, water is stored in the water tank 14 for cooling the thread rolling wheel 12 and the bolts, the water tank 14 is connected to the top of the water pipe 15, the base plate 11 is provided with a fixing mechanism, and the base plate 11 is provided with a cleaning mechanism.

[0029] like Figure 1-Figure 9As shown, the fixing mechanism includes a fixing clamp 2, a support frame 21, a first spring 22, a second spring 23, a turntable 211, a slide plate 24, a slider 25, a support plate 26, a slide bar 46, a third spring 42 and a placement block 43. The support frame 21 is fixedly connected to the front side of the base plate 11, and the support plate 26 is slidably connected to the support frame 21.

The slide plate 24 is fixedly connected to the rear side of the slider 25. The turntable 211 is rotatably connected to the rear side of the slide plate 24. A pair of fixing clamps 2 are slidably connected to the rear side of the turntable 211. The fixing clamp 2 is used to clamp the fixing bolts. The first spring 22 is fixedly connected between the fixing clamp 2 and the turntable 211. A pair of slide bars 46 are slidably connected to the rear side of the base plate 11. The third spring 42 is fixedly connected between the slide bar 46 and the base plate 11, and a placement block 43 is slidably connected between the pair of slide bars 46.

[0030] like Figure 5 and Figure 6 As shown, the cleaning mechanism includes a pressure plate 27, a friction block 28, a compression spring 29 and a pressure block 210. The pressure plate 27 is slidably connected to the middle of the bottom plate 11. The compression spring 29 distributed longitudinally front and back is fixedly connected between the pressure plate 27 and the bottom plate 11. The friction block 28 distributed longitudinally front and back is fixedly connected to the rear side of the top of the pressure plate 27. The pressure block 210 is fixedly connected to the front side of the top of the pressure plate 27.

[0031] like Figure 8-Figure 10 As shown, it also includes a top block 3, a support rod 31, a connecting rod 32, a rotating shaft 33, a guide rod 34, a rotating clamp 4, a pull rope 41, a torsion spring 44 and a limit rod 45. The protective shell 13 is rotatably connected to the rear side of the rotating shaft 33, and the connecting rod 32 is fixedly connected to the rotating shaft 33. The middle part of the bottom plate 11 is slidably connected to the guide rod 34, and the top block 3 is fixedly connected to the top of the guide rod 34. The top block 3 is used to lift the processed bolts, and a pair of support rods 31 are fixedly connected to the rear side of the top block 3, and a pair of limit rods 45 are fixedly connected to the rear side of the top block 3. The connecting rod 32 is rotatably connected to the support rod 31, and a pair of rotating clamps 4 are rotatably connected to the rear side of the bottom plate 11. A torsion spring 44 is fixed between the pair of rotating clamps 4, and a pair of pull ropes 41 are slidably connected inside the bottom plate 11. One end of the pull rope 41 is fixedly connected to the sliding rod 46, and the other end of the pull rope 41 is fixedly connected to the rotating clamp 4, and the rotating clamp 4 contacts the limit rod 45.

[0032] When the worker wants to process the bolt, he pushes the placement block 43 backward, driving the slide bar 46 to move backward, the third spring 42 is stretched immediately, and the pull rope 41 is straightened. At this time, the paired rotating clamps 4 are in a separated state, and the torsion spring 44 is in a deformed state. Because the paired rotating clamps 4 are in contact with the limit rod 45 and are restricted from rotating and closing under the action of the torsion spring 44, the bolt is placed in the placement block 43, and then the placement block 43 is released. The placement block 43, the bolt and the slide bar 46 move forward a short distance under the action of the third spring 42 resetting, the pull rope 41 is slightly relaxed, and the bolt moves forward a short distance to contact and squeeze the fixed clamp 2, causing the paired fixed clamp 2 to move backward, the first spring 22 is compressed immediately, and the bolt continues to move forward until it is in contact with the turntable 211 The bolt is then clamped and fixed by the paired fixing clamps 2 under the reset action of the first spring 22, and then the thread rolling wheel 12 is started to process the bolt. At the same time, the water tank 14 is opened to allow the water in the water tank 14 to flow out along the water pipe 15 to cool the thread rolling wheel 12 and the bolt. During the processing, the bolt will continue to move forward, and the placement block 43 and the slide bar 46 will move forward and rotate with the bolt under the reset action of the third spring 42, and the pull rope 41 will relax immediately. However, due to the existence of the limit rod 45, the rotating clamp 4 cannot rotate and reset, and the turntable 211, the slide plate 24 and the support plate 26 are squeezed and moved forward by the bolt. At this time, the turntable 211 and the fixing clamp 2 will also rotate with the bolt, and the second spring 23 will be compressed immediately, and the turntable 211 moves forward to pass When the pressing block 210 is inclined, the pressing block 210, the friction block 28 and the pressing plate 27 move upward under the action of the reset of the compression spring 29. The friction block 28 moves upward to contact the bolt and grinds and cleans the wire and burrs on the bolt. After the bolt processing is completed, the water tank 14 is closed to make the paired protective shells 13, the rotating shaft 33 and the thread rolling wheel 12 move in opposite directions. The paired rotating shafts 33 move in opposite directions to drive the connecting rod 32 to rotate to be parallel to the bottom plate 11, and the support rod 31, the top block 3, the limiting rod 45 and the guide rod 34 are moved upward. The upward movement of the top block 3 will lift the bolt, and the placement block 43, the fixing clamp 2, the turntable 211, the slide plate 24 and the slide block 25 are also moved upward. The limiting rod 45 moves upward to enter the groove of the rotating clamp 4 and no longer restricts the rotating clamp 4 rotates, and the rotating clamp 4 rotates towards each other and clamps the bolt under the reset action of the torsion spring 44. At this time, the worker can separate the rotating clamp 4 and remove the bolt, and then make the paired protective shell 13, the rotating shaft 33 and the thread rolling wheel 12 move towards each other, and the support rod 31, the top block 3, the limiting rod 45 and the guide rod 34 are moved downward and reset. The reset of the limiting rod 45 will prevent the rotating clamp 4 in the separated state from closing, and the sliding rod 46 and the placing block 43 move forward and return to their original positions under the reset action of the third spring 42. The paired fixed clamps 2 move towards each other and reset under the reset action of the first spring 22, and the sliding plate 24 and the rotating disk 211 and other components move backward and reset under the reset action of the second spring 23. At this time, the pressing block 210 moves downward and resets under the squeezing action of the rotating disk 211.The compression spring 29 is then compressed, and all components return to their original positions.

Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
