DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Reference Figure 1-7 A metal product processing tool for fire fighting, including a base plate 1, a plurality of movable pulleys 2 are fixedly installed on the bottom wall of the base plate 1, each movable pulley 2 is a universal wheel, and the universal wheel can rotate and move freely in all directions, which makes the equipment equipped with it can easily adapt to various complex moving routes and ground conditions, and two mounting frames 3 are fixedly installed on the upper end surface of the base plate 1, and hydraulic cylinders 4 are fixedly installed inside the two mounting frames 3. The working principle of the hydraulic cylinder 4 is based on the Pascal principle, that is, when the liquid in a closed container is subjected to pressure, the pressure will be evenly transmitted to various parts of the container by the liquid, which means that as long as the pressure acting on the liquid is increased, all parts of the entire system will be subjected to corresponding pressure, so that the hydraulic cylinder 4 can produce a large output Force, secondly, the structural design of the hydraulic cylinder 4 also enhances its pressure-bearing capacity. The hydraulic cylinder 4 usually has a sturdy cylinder body and piston, which can withstand the force of high-pressure liquid without deformation or damage. In addition, the seals in the hydraulic cylinder 4 also play a key role. They can ensure that the liquid will not leak under high pressure, thereby ensuring the stability and reliability of the hydraulic cylinder 4. Compared with the air cylinder, the hydraulic oil used in the hydraulic cylinder 4 has lower compressibility. Under the same pressure, the volume change of the hydraulic oil is much smaller than that of the gas, which makes the hydraulic cylinder 4 have higher efficiency and stability when transmitting pressure. Therefore, the hydraulic cylinder 4 can withstand and transmit greater pressure. When processing workpieces with larger mass, the reliability of the support can be increased by setting two hydraulic cylinders 4.

[0028] A telescopic opening is provided on the upper end surface of the base plate 1 for cooperating with the two hydraulic cylinders 4. The telescopic ends of the two hydraulic cylinders 4 are fixedly installed with support plates 5. A transmission shaft 7 and a rotating shaft 8 are rotatably installed on the upper end surface of the base plate 1 through a support frame 6. A first motor 9 connected to the rotating shaft 8 is fixedly installed on the outer wall of the support frame 6. The first motor 9 is a conical rotor motor. The conical rotor motor is a special motor whose stator inner cavity and rotor shape are both conical. In the case of power failure, the braking device of the conical rotor motor can act quickly to prevent the equipment from accidentally moving without power. Compared with electrical brakes, it is more reliable and ensures the safe operation of the equipment. The fixing of the inclination angle of the workpiece can be achieved, and the torque of the conical rotor motor is large, which can provide stronger power output to meet some application scenarios that require large torque drive. A connecting block 10 is fixedly installed on the outer wall of the rotating shaft 8. The outer walls on both sides of the connecting block 10 are fixedly connected to a U-shaped plate 12 through a connecting mechanism. The connecting mechanism includes a connecting rod 11 fixedly installed on the inner walls on both sides of the connecting block 10, and the ends of the two connecting rods 11 are fixedly connected to the inner wall of the U-shaped plate 12.

[0029] A semicircular tooth plate 13 is fixedly installed on the outer wall of the U-shaped plate 12, and the U-shaped plate 12 and the semicircular tooth plate 13 are consistent with the center of the rotating shaft 8. The outer wall of the transmission shaft 7 is connected to the semicircular tooth plate 13 through a rotating mechanism. The rotating mechanism includes a first gear 14 fixedly installed on the outer wall of the transmission shaft 7, and the first gear 14 is engaged with the semicircular tooth plate 13. A placement plate 15 is fixedly installed on the end of the U-shaped plate 12, and a double-headed screw 16 is rotatably installed on the upper end surface of the placement plate 15 through a movable groove. A second motor 17 connected to the double-headed screw 16 is fixedly installed on the outer wall of the placement plate 15, and two moving sleeves 19 are threadedly installed on the outer wall of the double-headed screw 16 through a limiting mechanism. The limiting mechanism includes a limiting rod 18 fixedly installed inside the movable groove, and the limiting rod 18 slides through the two moving sleeves 19. The limiting rod 18 can limit the two moving sleeves 19 so that the two moving sleeves 19 can only move axially along the outer wall of the double-headed screw 16.

[0030] The ends of the two movable sleeves 19 are fixedly installed with connecting frames 20, and the two connecting frames 20 are rotatably installed with connecting shafts 21. The outer walls of the two connecting shafts 21 are fixedly installed with mounting sleeves 22. The outer walls of the two mounting sleeves 22 are fixedly installed with multiple clamping plates 24 through a fixing mechanism. The fixing mechanism includes a fixing rod 23 fixedly installed on the outer wall of the mounting sleeve 22, and the end of the fixing rod 23 is fixedly connected to the outer wall of the clamping plate 24. The inner wall shape of each clamping plate 24 on the same side is different. The outer walls of the two connecting shafts 21 are fixedly installed with a second gear 25. The outer walls of the two connecting frames 20 are fixedly installed with electric telescopic rods 27 through connecting plates 26. The telescopic ends of the two electric telescopic rods 27 are fixedly installed with moving blocks 28. The outer walls of the two moving blocks 28 are fixedly installed with straight tooth plates 30 that mesh with the second gear 25 on the same side through a connecting mechanism. The connecting mechanism includes a fixing rod 23 fixedly installed on the outer wall of the moving block 28. The connecting rod 29 of the wall, the end of the connecting rod 29 is fixedly connected to the outer wall of the spur plate 30. Since the connecting plate 26 is fixedly installed on the outer wall of the connecting frame 20, the spur plate 30 and the second gear 25 are always in a bite state during the process of the connecting frame 20 being driven to move by the movable sleeve 19. The electric telescopic rod 27 is usually made of high-strength materials and precision manufacturing technology, and has high load-bearing capacity and stability. The electric telescopic rod 27 is widely used in various occasions requiring linear drive and precise control, such as automation equipment, stage equipment, medical equipment, industrial production lines, etc. In these applications, the electric telescopic rod 27 not only provides a stable driving force, but also realizes precise position control and automated operation. The two electric telescopic rods 27 are synchronously extended and retracted through an electrical synchronization method, thereby allowing the two second gears 25 to rotate with the same amplitude, so that the clamping plates 24 on both sides can be rotated and adjusted at the same frequency.

[0031] When the present invention is used, the bottom plate 1 can be conveniently moved by means of a plurality of movable pulleys 2. When it moves to a specified position, the two hydraulic cylinders 4 can extend downward through the lifting openings on the same side, respectively, so that the two support plates 5 can be moved downward to contact the ground, so that the bottom plate 1 can be stably placed through the cooperation of the two support plates 5. Before processing the workpiece, the two electric telescopic rods 27 can respectively drive the moving blocks 28 on the same side to move. At this time, the two moving blocks 28 can respectively drive the spur plates 30 on the same side to move through the cooperation of the connecting rods 29, so that the two spur plates 30 can respectively bite the second gears 25 on the same side. At this time, the two second gears 25 can respectively drive the connecting shafts 21 on the same side to rotate, so that the two connecting shafts 21 can respectively drive the multiple clamping plates 24 on the same side to rotate through the cooperation of the mounting sleeves 22 and the fixing rods 23, so that the appropriate clamping plates 24 can be selected according to the shape of the workpiece, so as to achieve effective clamping of workpieces with different shapes.

[0032] When clamping the workpiece, the second motor 17 can drive the double-headed screw 16 to rotate. When the double-headed screw 16 rotates, it can drive the two movable sleeves 19 to move by cooperating with the limit rod 18. At this time, the two movable sleeves 19 can respectively drive the connecting frame 20 on the same side to move, so that the two opposite clamping plates 24 can be close to each other to clamp the outer wall of the workpiece, so as to realize convenient fixation of the workpiece, and under the drive of the double-headed screw 16, the spacing between the two movable sleeves 19 can be conveniently adjusted, so that the distance between the two opposite clamping plates 24 can be adjusted, so that workpieces of different sizes can be clamped and fixed;

[0033] When the workpiece needs to adjust the inclination angle during processing, the first motor 9 can drive the transmission shaft 7 to rotate. When the transmission shaft 7 rotates, it can drive the first gear 14 to rotate and engage the semicircular toothed plate 13. At this time, the semicircular toothed plate 13 can transmit the force applied to the U-shaped plate 12. The U-shaped plate 12 can be driven to rotate the rotating shaft 8 through the cooperation of the connecting rod 11 and the connecting block 10. As a result, the U-shaped plate 12 can reach the placement plate 15 through the cooperation of the rotating shaft 8 to rotate and tilt, so that the placement plate 15 can drive the workpiece whose upper end surface is clamped and fixed to rotate and tilt, so as to adjust the workpiece. The processing angle can be conveniently adjusted to increase the convenience of the workpiece during operation, and the radius of the semicircular tooth plate 13 is larger than the first gear 14. According to the principle of gear transmission, when the two gears are meshed, their tooth ratio (that is, the ratio of the number of teeth of the first gear 14 to the number of teeth of the semicircular tooth plate 13) determines the conversion relationship between torque and speed. Specifically, if the number of teeth of the first gear 14 is less than the number of teeth of the semicircular tooth plate 13 (that is, the small gear drives the large gear), then the semicircular tooth plate 13 will obtain amplified torque and reduced speed, thereby accurately adjusting the inclination angle of the workpiece.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
