[0002] Polishing and grinding of metal pipes is an important processing process, which can make the surface of metal pipes smooth and beautiful, and can improve their corrosion resistance and service life. With the continuous development of industrial production, the requirements for polishing and grinding of metal pipes are getting higher and higher, and the traditional manual polishing and grinding methods can no longer meet the needs of production.

[0003] After searching, the existing Chinese patent announcement number is: CN207564305U, which provides an automatic polishing and grinding device for metal pipes. This patent adopts an all-round pipe surface polishing production line, and polishes the pipes to be processed entering the polishing and grinding ring through multiple grinding heads arranged in a ring. It not only improves the work efficiency, but also improves the polishing and grinding quality of the metal pipes, thereby improving the surface quality of the metal pipe surface and extending the service life of the metal pipe.

[0004] Although the above patent can improve work efficiency, the above-mentioned automatic polishing and grinding device for metal pipes still has the following problems: it is impossible to process metal pipes of different sizes, the processing equipment has poor versatility, the metal pipes have no protective structure during the processing, and the waste chips generated are easy to splash. At the same time, the waste chips cannot be processed, thereby affecting production.

[0005] In view of the above problems, an automatic polishing and grinding device for metal pipe is proposed. Utility Model Content

[0006] The utility model aims to provide an automatic polishing and grinding device for metal pipes, which solves the problems in the background technology that metal pipes of different sizes cannot be processed, the processing equipment has poor versatility, the metal pipes have no protective structure during the processing, the waste chips generated are easy to splash, and the waste chips cannot be processed, thus affecting production.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic polishing and grinding device for metal pipes, comprising a processing bed base, first racks are fixedly connected to the left and right sides of the top of the processing bed base, a processing head is arranged on the top of the processing bed base, a first rotating motor is fixedly connected to the inner center of the processing head, a three-grip chuck is fixedly connected to the output end of the first rotating motor, a second rotating motor is fixedly connected to the four corners of the bottom of the processing head, a first gear is fixedly connected to the output end of the second rotating motor, and the first gear is meshed with the first rack, and a grinding assembly is arranged on the front side of the processing bed base;

[0008] By adopting the above technical solution, the metal pipe is fixed on the three-jaw chuck, and the three-jaw chuck is driven to rotate by the rotation of the first rotating motor. The processing head is adjusted before and after the first rack to allow the metal pipe to enter the grinding assembly for processing. The high-speed rotation of the three-jaw chuck and the smooth adjustment of the processing head improve the processing accuracy of the metal pipe. The three-jaw chuck can quickly clamp and release the pipe, which is very convenient when loading and unloading the pipe, which helps to improve production efficiency. The three-jaw chuck is suitable for processing pipes of various sizes.

[0009] As a further description of the above technical solution: the grinding assembly includes a grinder, a grinding ring is fixedly connected to the inner center of the grinder, five positioning pins are penetrated and slidably connected to the rear side of the outer wall of the grinding ring, a second rack is fixedly connected to the center of the front side of the five positioning pins, a grinding block is fixedly connected to the bottom of the five positioning pins, a threaded toothed disk is rotatably connected to the front side of the outer wall of the grinding ring, an outer ring rack is fixedly connected to the outer ring of the threaded toothed disk, a third rotating motor is arranged on the left side of the bottom of the grinding ring, a second gear is fixedly connected to the output end of the third rotating motor, and the second gear is meshed with the outer ring rack, and a polishing assembly is arranged on the front side of the grinder;

[0010] By adopting the above technical solution, the third rotating motor rotates to drive the threaded toothed disc to rotate, and the upward and downward movement of the positioning pin is adjusted by rotating the threaded toothed disc. Various sizes of pipes can be processed, which means that the same processing equipment can be used to process products of different specifications, thereby reducing the need to purchase multiple fixed-size grinding rings and saving costs. When changing the processed product, the adjustable positioning pin only needs to be properly adjusted before it can continue to be used, which greatly reduces the time required to replace the grinding ring, thereby improving work efficiency.

[0011] As a further description of the above technical solution: a first pipe material inlet is opened at the center of the rear side of the grinder, and a first pipe material outlet is opened at the center of the front side of the grinder;

[0012] By adopting the above technical solution, the pipe material enters the grinder through the first pipe material inlet, so that the pipe material is processed inside the grinder, which increases the safety of the equipment and prevents the waste chips generated during the processing from splashing. After processing, the pipe material comes out from the first pipe material outlet, and the degree of automation is improved, which reduces the dependence on manual labor.

[0013] As a further description of the above technical solution: the polishing assembly includes a polishing machine, a fourth rotating motor is fixedly connected to the right side of the inner center of the polishing machine, a coarse-grained polishing wheel is fixedly connected to the output end of the fourth rotating motor, a fifth rotating motor is fixedly connected to the left side of the inner center of the polishing machine, and a fine-grained polishing wheel is fixedly connected to the output end of the fifth rotating motor;

[0014] By adopting the above technical scheme, different polishing processes can be achieved by adjusting the rotational speed of the fourth and fifth motors. The coarse-grained polishing wheel and the fine-grained polishing wheel can respectively perform different polishing tasks. For example, one is responsible for rough polishing and the other is responsible for fine polishing. This can better control the polishing process and improve the polishing quality. The two polishing wheels can polish the pipe material at the same time. Compared with a single polishing wheel, the processing time is halved, which significantly improves the polishing efficiency. The design of the double polishing wheels makes the polishing process smoother, reduces the bounce and vibration of the workpiece during the polishing process, and helps to improve the polishing accuracy.

[0015] As a further description of the above technical solution: a second pipe material inlet is opened at the rear center of the polishing machine, and a second pipe material outlet is opened at the front center of the polishing machine;

[0016] By adopting the above technical solution, the pipe enters the second pipe inlet after grinding, and passes through the second pipe inlet polishing machine again. The pipe is polished immediately after grinding, and output from the second pipe outlet after polishing. The automation system reduces the direct contact between workers and moving parts of the machine tool, reduces the risk of work-related accidents, improves the safety of the production process, prevents waste chips from splashing inside the polishing machine for processing, and realizes automated continuous production. The pipe can be automatically transported to the polishing position and automatically output after polishing is completed, reducing the manual handling process. Automated feeding and discharging reduces the time of manual operation, shortens the production cycle, and helps to improve the production efficiency of the polishing machine.

[0018] By adopting the above technical solution, a central controller can be set up to centrally manage the functions and operations of the processing head, grinder and polisher, making the operation easier and reducing the training time and difficulty of operators. The machine operation status can be checked through the control panel and adjusted through the control switch. Through the central controller, the operator can accurately adjust various parameters in the polishing process, such as speed, pressure, etc., to ensure the stability and consistency of the grinding and polishing quality.

[0019] As a further description of the above technical solution: a first waste opening is provided at the bottom center of the grinder, a first small waste cart is slidably connected to the bottom of the first waste opening, and first rollers are fixedly connected to the four corners of the bottom of the first small waste cart;

[0020] By adopting the above technical solution, the waste chips produced by grinding directly enter the first small waste cart through the first waste port, and are then properly processed by the first small waste cart to avoid being scattered on the workbench or in the surrounding environment, thereby keeping the workplace clean and safe. If the waste chips are not cleaned in time, they may enter the guide rails, slides and other key components of the machine tool, causing wear and damage. Effective waste chip recovery can reduce equipment failures and extend its service life.

[0021] As a further description of the above technical solution: a second waste opening is provided at the bottom center of the polishing machine, a second small waste cart is slidably connected to the bottom of the second waste opening, and second rollers are fixedly connected to the four corners of the bottom of the second small waste cart;

[0022] By adopting the above technical solution, a second waste port is set at the bottom of the polishing machine, and various waste chips generated during the polishing process (such as metal powder, grinding paste, polishing cloth fragments, etc.) enter the second small waste cart through the second waste port, avoiding them from being scattered in the workplace, thereby maintaining a clean working environment. Waste chips that are not cleaned up in time may enter the mechanical parts of the polishing machine, causing wear or damage. By opening the second waste port and the second small waste cart device, such problems can be reduced, thereby extending the service life of the equipment.
