[0002] For the surface grinding and polishing of pipes, there are currently two mainstream processing technologies in factories. The first is that workers use handheld grinders to grind and polish the surface of pipes or hold pipes on desktop grinders. This method has high labor intensity, low safety factor and low efficiency; the second is to use common grinding and polishing equipment on the market for grinding and polishing. This grinding and polishing equipment has a relatively simple structure and is mainly composed of several pairs of facing grinding and polishing wheels. The pipe is controlled to pass through the working surface of the grinding and polishing wheel to complete its surface treatment. The feed amount cannot be accurately controlled during the feeding process. If the feed amount is too large to ensure the clamping force required for stable feeding, it will cause scratches on the surface of the pipe. If the feed amount is too small, the grinding and polishing effect is not ideal.

[0035] In a possible scheme, the first driving assembly includes a first transverse moving assembly 41, a first longitudinal moving assembly 42, a first mounting seat 43, a swing motor 44, a swing seat 45, a first crank mechanism 46 and a grinding head motor 47, the first transverse moving assembly 41 is arranged on the frame 7, the first longitudinal moving assembly 42 is arranged on the first transverse moving assembly 41, the first mounting seat 43 is arranged on the first longitudinal moving assembly 42, the swing seat 45 is rotatably connected to the first mounting seat 43, the swing motor 44 is connected to one side of the swing seat 45 through the first crank mechanism 46, the grinding head motor 47 is arranged on the other side of the swing seat 45, and the grinding head motor 47 is connected to the grinding and polishing wheel 49.

In order to drive the swing seat 45 to swing, a swing motor 44 can be set on the first mounting seat 43 and connected to the swing seat 45 through a first driving mechanism. A grinding head motor 47 is set on the swing seat 45. The grinding head motor 47 is used to drive the grinding and polishing wheel 49 to rotate. In this way, under the automatic control of the control system 5, the position of the grinding and polishing wheel 49 is adjusted through the first driving component so that the grinding and polishing wheel 49 contacts the surface of the pipe 6 in the processing area;

[0037] In a further improvement of this optional scheme, a gas spring 48 is provided on the side of the swing seat 45 away from the grinding head motor 47, one end of the gas spring 48 is connected to the swing seat 45, and the other end of the gas spring 48 is hinged to the first mounting seat 43; it also includes a waxing component 9, which is arranged close to the head component 4, and the waxing component 9 includes a second drive component, a wax strip seat and a wax strip, the second drive component is arranged on the frame 7, the second drive component is connected to the wax strip seat, and the wax strip is arranged on the wax strip seat, so as to drive the wax strip to contact the grinding and polishing wheel 49 through the second drive component.

The detection sensing switch 8 can be a travel switch, which is provided on the side of the processing table 3 close to the material preparation table 1. The detection sensing switch 8 can determine whether the feeding component 2 successfully clamps the pipe 6. When the feeding component 2 clamps the pipe 6 and moves to the sensing area of ​​the detection sensing switch 8, that is, above the travel switch, the feeding component 2 moves downward, so that the pipe 6 touches the travel switch, indicating that the clamping is successful. If the feeding component 2 moves downward at the detection position and no pipe touches the travel switch, it means that the clamping fails and the pipe 6 needs to be re-clamped.

[0040] When using the utility model, first, the worker displays the pipe 6 to be processed on the material preparation table 1, and the control system 5 controls the material holding parts 21 of the feeding components 2 on both sides to move synchronously to the two ends of a pipe 6, rotate to the zero position, move downward, move toward the inner hole of the pipe 6 and insert it into the pipe 6 at the same material taking position, clamp the pipe 6, and move upward, then move the clamped pipe 6 to the top of the detection induction switch 8, and move downward to touch the detection induction switch 8 to detect whether the pipe 6 is clamped successfully. If it fails, the feeding component 2 returns to the material preparation table 1 to clamp again. If it succeeds, it moves upward again, translates to the area above the processing table 3, and then moves downward to make the lower surface of the pipe 6 fit the rubber roller 31, and the feeding component 2 keeps the pipe 6 fixed on the surface of the rubber roller 31;

[0041] Then, under the control of the control system 5, the position of the head assembly 4 is adjusted, the swing motor 44 rotates, the first crank mechanism 46 drives the swing seat 45 and the grinding head motor 47 to swing downward, and overcome the resistance set by the gas spring 48 under the action of gravity, so that the grinding and polishing wheel 49 contacts the upper surface of the processed pipe 6 with a constant pressure, and the grinding head motor 47 is started. At this time, the rotating grinding and polishing wheel 49 begins to grind and polish, and the grinding and polishing wheel 49 moves in the horizontal plane to complete the processing of the upper surface of the entire pipe 6; in the process of the grinding and polishing wheel 49 processing the pipe 6, the motor of the second drive assembly rotates through the second crank mechanism (driving the wax strip seat, so that the wax strip moves downward under the action of gravity and contacts the grinding and polishing wheel 49 with a constant pressure to realize waxing the grinding and polishing wheel 49. After the grinding is completed, the motor of the second drive assembly continues to reverse, and the waxing process ends when the second crank mechanism drives the wax strip seat to move upward to the top dead center during the return journey;

[0042] After the grinding and polishing wheel 49 completes the processing of one side of the pipe 6, the swing motor 44 drives the swing seat 45 and the grinding head motor 47 to swing upward. After the grinding and polishing wheel 49 is lifted, it is translated out of the area above the processing table 3. The material holding piece 21 clamps the pipe 6 and moves upward, and rotates the turning assembly 22 to change the upper surface of the pipe 6 and then moves downward. The lower surface of the pipe 6 is then attached to the rubber roller 31. At this time, the above steps are repeated to start the grinding and polishing work on the other side of the pipe 6. The above process is repeated for multiple cycles to complete the grinding and polishing work of all the outer surfaces of the pipe 6 on the processing table 3. Finally, after the grinding and polishing wheel 49 completes the processing of the entire pipe 6, the swing motor 44 continues to drive the swing seat 45 and the grinding head motor 47 to swing Move up, the grinding and polishing wheel 49 is lifted and then moved horizontally out of the area above the processing table 3, the material holding piece 21 clamps the pipe 6 that has just been processed, moves up and rotates to the zero position, and then moves to the area above the preparation table 1, and then the pipe 6 that has just been processed is placed on the vacant material picking position, and the left and right material holding pieces 21 move synchronously to the next material picking position again, clamp another pipe 6 to be processed, and repeat the above process for processing; when the grinding and polishing machine is running the grinding and polishing work, the worker can take away the processed pipe 6 on the preparation table 1, and add the pipe 6 to be processed at the same time. At this point, the grinding and polishing machine can automatically cycle work, and according to the effect of grinding and polishing, the same pipe 6 can also be automatically ground and polished in this way for multiple times.

[0043] It is worth noting that the present application also includes a control system 5, which can be a PLC control for realizing the automatic use and operation of various components.
