[0024] The bottom of work box 1 is fixedly connected with hydraulic cylinder, the bottom end of hydraulic cylinder is fixedly connected with guide seat, the guide seat can be installed on cutting machine tool, one end of drive disc 31 is provided with annular distribution of drive hole, the surface of clamping frame 32 is fixedly connected with rubber sleeve, the surface of rubber sleeve is slidably connected to the inner wall of drive hole, the rubber sleeve avoids the displacement of clamping frame 32 in drive disc 31 during cutting production, one-way air outlet pipe 38 includes exhaust pipe and first one-way valve, the bottom end of exhaust pipe is communicated with the top of slide frame 33, the first one-way valve is embeddedly installed on the surface of exhaust pipe, the first one-way valve is used for blocking the outside gas entering into slide frame 33 through exhaust pipe.
[0025] When cutting production is needed for pull rod, the pull rod is inserted into the inner side of fixed disc 2 and the servo motor 37 is manually started, the output shaft of servo motor 37 rotates to drive second gear 36 to rotate, the diameter of second gear 36 is smaller than that of first gear 35, the specific gear diameter ratio can be selected according to actual demand, and will not be described again, second gear 36 rotates to drive first gear 35 and drive disc 31 to rotate slowly, drive disc 31 slowly rotates to drive three clamping frames 32 to move close to each other, the movement of clamping frame 32 drives slide frame 33 and rubber block 34 to move, so that rubber block 34 abuts against the pull rod, drive disc 31 continues to drive slide frame 33 to move close to the pull rod, the movement of rubber block 34 pushes the gas in slide frame 33 to discharge through one-way air outlet pipe 38, at this time, the servo motor 37 is manually turned off, so that three groups of rubber blocks 34 abut against the surface of pull rod, at this time, the cutting equipment starts to cut the fixed pull rod.
[0026] As shown in, Figure 4 The top of one of rubber blocks 34 is fixedly connected with identification rod 311, the top of one of slide frames 33 is fixedly connected with observation ring 312, the surface of identification rod 311 is slidably connected to the inner wall of observation ring 312.
[0027] AsFigure 4 As shown, the top of the sliding frame 33 is connected to a one-way air inlet pipe 310. Several spring pieces 39 are fixedly connected to the inner top wall of the sliding frame 33. The bottom end of the spring piece 39 is fixedly connected to the top of the rubber block 34. Filter frames 313 are fixedly connected to the tops of both the one-way air outlet pipe 38 and the one-way air inlet pipe 310. The surface of the filter frame 313 is frustoconical. The one-way air inlet pipe 310 includes an air guide pipe and a second one-way valve. The bottom end of the air guide pipe is connected to the top of the sliding frame 33. The surface of the second one-way valve is embedded in the surface of the air guide pipe. The second one-way valve is used to prevent gas inside the sliding frame 33 from being discharged through the air guide pipe.
[0028] After the tie rod cutting production is completed, the servo motor 37 is manually turned on. The output shaft of the servo motor 37 rotates, which drives the drive disk 31 to rotate slowly through the first gear 35 and the second gear 36. The rotation of the drive disk 31 drives the three clamps 32 to move away from each other, so that the rubber block 34 moves away from the tie rod surface, releasing the fixation on the tie rod. The operator can take out the produced tie rod. The elastic force of the spring 39 pushes the rubber block 34 to move down. The movement of the rubber block 34 causes a suction force to be generated in the slide frame 33, allowing external gas to enter the slide frame 33 through the one-way air inlet pipe 310, so that a certain amount of gas is stored in the slide frame 33.
[0029] like Figure 3 As shown, telescopic pads 314 are fixedly connected to both the top and bottom of the clamp 32, and the ends of the telescopic pads 314 are fixedly connected to the inner wall of the fixed plate 2. The telescopic pads 314 are rubber components.
[0030] In use, the pull rod is inserted into the inner side of the fixed plate 2 and the servo motor 37 is manually turned on. The output shaft of the servo motor 37 rotates, which drives the first gear 35 and the drive plate 31 to rotate slowly through the second gear 36 and the first gear 35. The drive plate 31 rotates slowly, which drives the three clamps 32 to move closer to each other. The movement of the clamps 32 drives the sliding frame 33 and the rubber block 34 to move, so that the rubber block 34 abuts against the pull rod. The drive plate 31 continues to drive the sliding frame 33 to move closer to the pull rod. As the rubber block 34 moves, it pushes the gas in the sliding frame 33 to be discharged through the one-way vent pipe 38 and squeezes the spring 39. When the inner wall of the observation ring 312 slides to the surface of the marker rod 311, the servo motor 37 is manually turned off, so that the three sets of rubber blocks 34 press against the surface of the pull rod. At this time, the cutting equipment starts to cut the fixed pull rod.
[0031] It should be noted that the working box 1, hydraulic cylinder, guide seat, servo motor 37, first check valve and second check valve mentioned above are all components with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the hydraulic cylinder and servo motor 37 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.
