DETAILED DESCRIPTION

[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0023] A fully automatic pipe bending polishing machine, such as Figures 1 to 3 As shown, it includes a frame 1, a clamping member 2, a driving assembly, a turning assembly, a moving assembly and a polishing wheel assembly.

[0024] The clamping member 2 is arranged on the frame 1, and is used to clamp the bent pipe. The clamping member 2 is used to clamp the two ends of the bent pipe to ensure the stability of the bent pipe during the polishing process. The clamping member 2 can adopt the clamp for clamping the pipe body in the existing technology, and its specific structure will not be described in detail.

[0025] The polishing wheel assembly is used to polish both sides of the bent pipe. The polishing wheel assembly includes two polishing motors 61 and two polishing wheel bodies 62. The output ends of the two polishing motors 61 are respectively connected to the corresponding polishing wheel bodies 62. The two polishing wheel bodies 62 are spaced apart and arranged opposite to each other. The two polishing wheel bodies 62 are respectively located on both sides of the bent pipe. The corresponding polishing wheel bodies 62 are driven to rotate by the polishing motors 61 to perform polishing operations.

[0026] The driving assembly is used to drive the polishing wheel assembly to move along the bent pipe and always keep it close to the bent pipe. The driving assembly includes a cross module slide 31 and a worm gear reducer 32. The cross module slide 31 is set on the frame 1, and a base 7 is slidably set on the frame 1. The cross module slide 31 is used to drive the base 7 to slide. The cross module slide 31 is composed of two linear modules with relatively vertical driving directions. The worm gear reducer 32 is set on the base 7, and a support seat 8 is rotatably set on the base 7. The output end of the worm gear reducer 32 is connected to the support seat 8.

[0027] The polishing wheel assembly is connected to the support seat 8, that is, the base 7 is driven to slide through the cross module slide 31, and the base 7 drives the worm gear reducer 32, the support seat 8 and the polishing wheel assembly to move. The support seat 8 is driven to rotate by the worm gear reducer 32, and the support seat 8 drives the polishing wheel assembly to rotate. Through the sliding of the base 7 and the rotation of the support seat 8, the position of the polishing wheel body 62 is adjusted in real time, so that the polishing wheel body 62 moves along the bent pipe and always sticks to the bent pipe, thereby completing the polishing operation on both sides of the bent pipe at the same time.

[0028] The flipping assembly is used to flip the polishing wheel assembly so that the polishing wheel assembly is opposite to the other two sides of the bent pipe. The flipping assembly includes a flipping motor 41 and a mounting seat 42. The flipping motor 41 is installed on the support seat 8. The axis direction of the output end of the flipping motor 41 is relatively perpendicular to the axis direction of the output end of the worm gear reducer 32. The mounting seat 42 is rotatably set on the support seat 8, the polishing wheel assembly is connected to the mounting seat 42, and the output end of the flipping motor 41 is connected to the mounting seat 42. Specifically, an annular guide rail 9 is provided on the support seat 8, and the mounting seat 42 is slidably set on the annular guide rail 9.

[0029] The polishing motor 61 and the polishing wheel body 62 are both slidably connected to the mounting seat 42. The mounting seat 42 is provided with a linear slide rail 10. The linear slide rail 10 is provided with a slider 11. The slider 11 is connected to a base 12. The polishing motor 61 is installed on the base 12. The polishing wheel body 62 is rotatably set on the base 12.

[0030] The mounting seat 42 is driven to rotate along the annular guide rail 9 by the flip motor 41, and the mounting seat 42 drives the linear slide rail 10, the slider 11, the base 12, the polishing motor 61 and the polishing wheel body 62 to flip 90 degrees, so that the two polishing wheel bodies 62 correspond to the other two sides of the bent pipe respectively.

[0031] The output end of the polishing motor 61 is coaxially connected with a transmission wheel 13, and a transmission wheel 2 14 is rotatably arranged on the base 12. The transmission wheel 2 14 is coaxially connected to the polishing wheel body 62, and the transmission wheel 13 and the transmission wheel 2 14 are connected through a transmission belt 15. That is, the transmission wheel 13 is driven to rotate by the output end of the polishing motor 61, and the transmission wheel 13 drives the transmission wheel 2 14 to rotate through the transmission belt 15, and the transmission wheel 2 14 drives the polishing wheel body 62 to rotate.

[0032] It should be noted that after the polishing wheel assembly is turned over, the position will be offset due to the influence of gravity, so the position of the polishing wheel assembly needs to be adjusted to ensure that the two polishing wheel bodies 62 are close to the two sides of the curved pipe.

[0033] The moving assembly is used to move the flipped polishing wheel assembly so that it is close to the bent pipe. Specifically, the moving assembly includes two cylinders 51. The cylinder 51 is installed on the mounting seat 42. The cylinder 51 is used to drive the corresponding polishing motor 61 and the polishing wheel body 62 to slide, so that the polishing wheel body 62 is close to the bent pipe. The output end of the cylinder 51 is connected to the base 12, and the base 12 is driven by the cylinder 51. The base 12 and the slider 11 move along the linear slide rail 10. The base 12 drives the corresponding polishing motor 61 and the polishing wheel body 62 to move, so that the two polishing wheel bodies 62 are close to the two sides corresponding to the bent pipe, and finally the polishing operation is performed.

[0034] The cross module slide 31 , the worm gear reducer 32 , the flip motor 41 , the polishing motor 61 , and the cylinder 51 are all electrically connected to an external controller, and the external controller can detect the current intensity of the polishing motor 61 .

[0035] It should be noted that when the polishing wheel body 62 is not close to the bent pipe, the amount of electricity required to be output by the polishing motor 61 to drive the polishing wheel body 62 to rotate is relatively small, while the polishing wheel body 62 is close to the bent pipe. Due to the friction between the polishing wheel body 62 and the bent pipe, the amount of electricity required to be output by the polishing motor 61 to drive the polishing wheel body 62 to rotate is relatively large. Therefore, by detecting the current intensity of the polishing motor 61 through an external controller, it can be determined whether the current polishing wheel body 62 is close to the bent pipe, and then control whether the cylinder 51 is started to move the polishing wheel body 62.

[0036] Here’s how it works:

[0037] The output end of the polishing motor 61 drives the transmission wheel 13 to rotate, and the transmission wheel 13 drives the transmission wheel 2 14 to rotate through the transmission belt 15, and the transmission wheel 2 14 drives the polishing wheel body 62 to rotate, and the cross module slide 31 drives the base 7 to slide, and the base 7 drives the worm gear reducer 32, the support seat 8, the flip motor 41, the mounting seat 42, the cylinder 51, the base 12, the polishing motor 61 and the polishing wheel body 62 to move, and the worm gear reducer 32 drives the support seat 8 to rotate, and the support seat 8 drives the flip motor 41, the mounting seat 42, the cylinder 51, the base 12, the polishing motor 61 and the polishing wheel body 62 to rotate, and the two polishing wheel bodies 62 are moved along The two sides of the bent pipe move and always stick to the bent pipe to complete polishing; then the flip motor 41 drives the mounting seat 42 to rotate, and the mounting seat 42 drives the cylinder 51, the base 12, the polishing motor 61 and the polishing wheel body 62 to rotate, so that the two polishing wheel bodies 62 are opposite to the other two sides of the bent pipe; then the external controller controls the cylinder 51 to start, and the cylinder 51 drives the base 12 and the slider 11 to move along the linear slide rail 10, and the base 12 drives the corresponding polishing motor 61 and the polishing wheel body 62 to move, so that the two polishing wheel bodies 62 are close to the two sides corresponding to the bent pipe; finally, the above polishing action is repeated, so that the two polishing wheel bodies 62 polish both sides of the bent pipe.

[0038] It should be noted that the polishing machine can complete the all-round polishing operation of the bent pipe in a fully automated manner, and can complete the all-round polishing without changing the state of the bent pipe for re-clamping. This not only effectively improves the efficiency of the all-round polishing operation, but also ensures the polishing accuracy.

[0039] It should be further explained that the bent pipe polishing machine disclosed in this embodiment is used to perform finishing and polishing operations on various pipe fittings, including kitchen utensils, bathroom facilities, door handles, handrails and other pipe fittings.

[0040] A polishing method based on a fully automatic pipe bending polishing machine, the polishing method comprising the following steps:

[0041] Step 1: The polishing motor 61 drives the corresponding polishing wheel body 62 to rotate;

[0042] Step 2: The cross module slide 31 drives the base 7 to slide, and the worm gear reducer 32 drives the support seat 8 to rotate, so that the two polishing wheel bodies 62 move along the two sides of the bent pipe and always stick to the bent pipe to complete the polishing;

[0043] Step 3: The flip motor 41 drives the mounting seat 42 to rotate, and the mounting seat 42 drives the cylinder 51, the base 12, the polishing motor 61 and the polishing wheel body 62 to rotate, so that the two polishing wheel bodies 62 are opposite to the other two sides of the bent pipe;

[0044] Step 4: Preset the current range of the polishing motor 61 on the external controller, the external controller detects the real-time current of the polishing motor 61 and compares it with the preset current range of the polishing motor 61, and determines whether the real-time current of the polishing motor 61 meets the preset current range;

[0045] Step 5: When the real-time current of the polishing motor 61 meets the preset current range, the cross module slide 31 drives the base 7 to slide, and the worm gear reducer 32 drives the support seat 8 to rotate, so that the two polishing wheel bodies 62 move along the two sides of the bent pipe and always stick to the bent pipe to complete polishing. On the contrary, the real-time current of the polishing motor 61 does not meet the preset current range, then the external controller first controls the cylinder 51 to start, and the cylinder 51 drives the corresponding base 12 to slide, so that the two polishing wheel bodies 62 are close to the bent pipe, and then repeat step 2.
