It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0018] Embodiment 1: A metal pipe edge grinding device, as Figures 1 - 3 shown, includes a bottom plate 1, a support frame 2, rollers 3, a fixed rod 4, a swing frame 5, a long roller 6, a torsion spring 7, a metal pipe 8, a transmission assembly and a grinding assembly. Two support frames 2 are fixedly connected to the top of the bottom plate 1. Two rollers 3 are rotatably connected to the upper parts of the two support frames 2. A fixed rod 4 is fixedly connected to the top of the bottom plate 1. A swing frame 5 is rotatably connected to the fixed rod 4. A long roller 6 is rotatably connected to the swing frame 5. A torsion spring 7 is connected between the swing frame 5 and the fixed rod 4. A metal pipe 8 is placed between the four rollers 3 and the long roller 6. The rollers 3 are used to drive the metal pipe 8 to rotate. A transmission assembly and a grinding assembly are provided on the bottom plate 1. The long roller 6 is used to fix metal pipes 8 with different diameters. The transmission assembly drives one of the rollers 3 to rotate. The rotation of the roller 3 can drive the metal pipe 8 to rotate, so that the grinding assembly can grind the sharp edges of the inner and outer pipe orifices of the metal pipe 8, improving the grinding efficiency.

[0019] The transmission assembly includes a fixed frame 91, a motor 9, a pulley 10 and a first transmission belt 11. A fixed frame 91 is fixedly connected to the top of the bottom plate 1. A motor 9 is fixedly connected to the fixed frame 91. A pulley 10 is fixedly connected to the output shaft of the motor 9. A first transmission belt 11 is wound between the pulley 10 and one of the rollers 3. The first transmission belt 11 is used to drive the roller 3 to rotate.

[0020] The grinding assembly includes a support plate 12, a rotating block 13, a grinding rod 14 and a return spring 15. A support plate 12 is provided on the top of the bottom plate 1. Two rotating blocks 13 are rotatably connected to the support plate 12. Grinding rods 14 are slidably connected to the two rotating blocks 13. A return spring 15 is connected between the grinding rod 14 and the rotating block 13.

[0021] The two grinding rods 14 are used to grind the inner and outer pipe openings of the metal pipe respectively.

[0022] In actual use, the worker moves the swing frame 5, the torsion spring 7 is twisted, and then the worker places the metal tube 8 between the four rollers 3 and pushes the metal tube 8 between the two grinding rods 14. The metal tube 8 will squeeze the two grinding rods 14, and the two grinding rods 14 will slide on the rotating block 13, so that one of the grinding rods 14 is close to the outer tube mouth of the metal tube 8, and the other grinding rod 14 is close to the inner tube mouth of the metal tube 8. The two reset springs 15 are compressed to facilitate the grinding of metal tubes 8 of different diameters. The worker stops moving the swing frame 5, and the torsion spring 7 drives the swing frame 5 to reset, so that the long roller 6 on the swing frame 5 is close to the metal tube 8. The worker starts the motor 9, and the output shaft of the motor 9 drives the pulley 10 to rotate. The rotation of the pulley 10 drives one of the rollers 3 to rotate through the transmission belt 11, and the rotation of one of the rollers 3 drives the metal tube 8 to rotate, so that the two grinding rods 14 continuously grind the inner and outer pipe openings of the metal tube 8, thereby quickly grinding the inner and outer sharp edges of the metal tube 8 material ports to improve the grinding efficiency. Then the worker turns off the motor 9, and the worker moves the swing frame 5 to make the long roller 6 break away from the contact with the metal tube 8. The worker takes away the polished metal tube 8, and the worker releases the swing rod, and the torsion spring 7 drives the swing frame 5 to reset.

[0023] Embodiment 2: Based on embodiment 1, Figure 4 As shown, it also includes a transmission rod 16, a transmission wheel 17, a transmission belt 18, a driving gear 19 and a transmission gear 20.

The transmission rod 16 is used to drive the transmission wheel 17 to rotate, and one of the rotating blocks 13 is also fixedly connected to the transmission wheel 17. A transmission belt 18 is wound between the two transmission wheels 17. One end of one of the grinding rods 14 is fixedly connected to the driving gear 19, and one end of the other grinding rod 14 is fixedly connected to the transmission gear 20, and the driving gear 19 is meshed with the transmission gear 20.

[0024] The rotation of the pulley 10 drives the rotation of the transmission rod 16. The rotation of the transmission rod 16 drives the rotation of one of the transmission wheels 17. The rotation of one of the transmission wheels 17 drives the rotation of the other transmission wheel 17 through the second transmission belt 18. The rotation of the other transmission wheel 17 drives the rotation of the rotating block 13. The rotation of the rotating block 13 away from the transmission rod 16 drives the rotation of the grinding rod 14 away from the transmission rod 16. The rotation direction of the grinding rod 14 away from the transmission rod 16 is opposite to the rotation direction of the metal tube 8, so that the grinding rod 14 away from the transmission rod 16 can better grind the sharp edge of the inner pipe orifice of the metal tube 8. The rotation of the grinding rod 14 away from the transmission rod 16 drives the rotation of the transmission gear 20. The rotation of the transmission gear 20 drives the rotation of the driving gear 19. The rotation of the driving gear 19 drives the rotation of the rotating block 13 close to the transmission rod 16. The grinding rod 14 close to the transmission rod 16 can better grind the sharp edge of the outer pipe orifice of the metal tube 8, so as to achieve a better grinding effect and improve the grinding efficiency.
