[0020] The present invention provides a polishing device for flattening roller processing. It has the following beneficial effects:

[0021] 1. The polishing equipment for flattening roller processing, the clamping assembly clamps the outer surface of the bent pipe, and then uses the three-jaw chuck to completely clamp the mandrel, so that the bent pipe and the mandrel are quickly aligned. As the telescopic motor continues to push, the clamping assembly completely clamps the surface of the bent pipe, and the screw slide drives the arc surface grinding mechanism to move linearly, thereby grinding and polishing the surface of the bent pipe, solving the problem of how to grind and polish the flattening roller of the bending axis to make the subsequent rubber coating effect better.

[0022] 2. The flattening roller processing polishing equipment has two oppositely arranged rubber half-tubes that completely clamp the surface of the bent pipe. The driving motor drives the worm to rotate, and the surface of the worm meshes with the surface of the first half wheel. The first half wheel and the second half wheel form a complete worm wheel. As the worm rotates, the worm wheel rotates on the inner side of the shell. The pressure plate supports and limits the worm wheel in rotation, so that the bent pipe can rotate stably around the core shaft, and the arc surface grinding mechanism can stably grind and polish the surface of the bent pipe.

[0023] 3. The polishing equipment for flattening roller processing drives the motor to drive the grinding wheel to rotate, and the grinding wheel polishes the surface of the bent pipe. The lubrication component transports the polishing paste to the surface of the grinding wheel to lubricate it. The atomization component promotes the lubrication effect of the polishing paste. The driving component makes the clamping component rotate slowly around the core shaft. The protective plate is arranged directly below the grinding wheel to guide a small amount of lubricating liquid, which solves the problem that the poor lubrication effect of water during the polishing process easily leads to uneven surface of the flattening roller.

[0024] 4. The polishing equipment for flattening roller processing has a small gap between the outer surface of the rotating roller and the inner side of the cylindrical shell because the rotating roller is set downward. The surface of the rotating roller contacts the surface of the grinding wheel. As the reduction motor drives the rotating roller to rotate, the rotating roller applies the polishing paste to the surface of the grinding wheel. The water spraying direction of the atomizing nozzle is set tangent to the surface of the grinding wheel. The surface of the grinding wheel is coated with polishing paste and then sprayed with water. Compared with using water alone for lubrication, this method makes the polishing effect of the bent pipe better.

[0025] 5. The polishing equipment for flattening roller processing has water stored in the water tank. The atomized water from the atomizing nozzle makes the polishing paste more fluid during lubrication. The inner sides of the first half wheel and the second half wheel firmly clamp the surface of the curved pipe. The height and horizontal positions of the cutting shell and the shell are adjustable. When the first half wheel and the second half wheel clamp the curved pipe near the edge, the grinding wheel polishes the curved pipe near the middle. When the grinding wheel polishes the edge of the curved pipe, the shell moves to the position near the middle of the curved pipe for clamping, so that the surface of the curved pipe is polished.

[0040] The elbow clamping mechanism 7 includes a sliding cylinder 71, a thread lifter 72 is fixedly connected to the edge of the sliding cylinder 71, an inner side of the thread lifter 72 is threadedly connected to an internal thread block 73, an inner side of the internal thread block 73 is fixedly connected to a telescopic motor 74, an output end of the telescopic motor 74 is fixedly connected to a driving component 76, and an inner side of the driving component 76 is rotatably connected to a clamping component 77;

[0041] The slide cylinder 71 is slidably mounted on the surface of the guide slide platform 2 . There are two telescopic motors 74 . A stabilizing body 75 is fixedly connected between the output end of the telescopic motor 74 and the driving assembly 76 .

[0042] When in use, the flattening roller is composed of a core shaft, bearings and a bent pipe. A plurality of bearings are fixedly connected between the inner side of the bent pipe and the core shaft. The bearings enable the bent pipe to rotate around the bent core shaft, which makes it more difficult to grind and polish the outer surface of the bent pipe. In the device, two three-jaw chucks 5 arranged opposite to each other support the two end faces of the core shaft. Subsequently, the sliding cylinder 71 slides on the surface of the guide slide 2, and the telescopic motor 74 drives the two driving assemblies 76 to move in opposite directions. The clamping assembly 77 clamps the outer surface of the bent pipe. Subsequently, the three-jaw chuck 5 is used to completely clamp the core shaft, so that the bent pipe and the core shaft are quickly aligned. As the telescopic motor 74 continues to push, the clamping assembly 77 completely clamps the surface of the bent pipe, and the screw slide 6 drives the arc grinding mechanism 8 to move in a straight line, thereby grinding and polishing the surface of the bent pipe, solving the problem of how to grind and polish the flattening roller of the bending axis so that the subsequent rubber coating effect is better.

[0043] Second embodiment: Figure 3 , Figure 4 , Figure 5 As shown, the driving assembly 76 includes a housing 761, the middle portion of the housing 761 is fixedly mounted on the output end of the telescopic motor 74, the surface of the housing 761 is fixedly connected to the driving motor 762, the driving assembly 76 also includes a worm 763, the worm 763 is fixedly mounted on the output end of the driving motor 762, and the inner side of the housing 761 is fixedly connected to a pressing plate 764;

[0044] The clamping assembly 77 includes a first half wheel 771, which is rotatably mounted on the inner side of the shell 761. The surface of the first half wheel 771 is fixedly connected to a pin 772. The surface of the first half wheel 771 meshes with the surface of the worm 763. The clamping assembly 77 also includes a second half wheel 773, which is rotatably mounted on the inner side of the shell 761. The surface of the second half wheel 773 is provided with a straight hole 774.

[0045] When in use, the telescopic motor 74 drives the two shells 761 to move towards each other. The working principle of the telescopic motor 74 is mainly based on the electromagnetic principle. The coil in the motor generates a magnetic field through the current, which interacts with the magnetic field generated by the permanent magnet to generate torque, causing the motor to rotate. While the motor rotates, the gear box converts the rotational motion into linear motion, thereby realizing the telescopic movement of the telescopic rod. The telescopic motor usually has a controller, and the amplitude, speed and direction of extension and rotation can be controlled by the controller. The controller can also be adjusted according to actual needs to make the movement of the motor more precise and stable. At this time, the end faces of the second half wheel 773 and the first half wheel 771 are flush with the end face of the shell 761. As the shell 761 approaches, the bent pipe is pushed, and the bending direction of the bent pipe is vertical. Straight downward, as the telescopic motor 74 continues to push, the pin 772 slides into the interior of the straight hole 774, the first half wheel 771 and the second half wheel 773 are completely connected, the surface of the rubber half tube 775 is tightly fitted with the surface of the bent pipe, and the two oppositely arranged rubber half tubes 775 completely clamp the surface of the bent pipe, and the driving motor 762 drives the worm 763 to rotate, and the surface of the worm 763 is meshed with the surface of the first half wheel 771. The first half wheel 771 and the second half wheel 773 form a complete worm wheel. As the worm 763 rotates, the worm wheel rotates on the inner side of the shell 761, and the pressure plate 764 supports and limits the worm wheel in rotation, so that the bent pipe can rotate stably around the core axis, and the arc grinding mechanism 8 can stably grind and polish the surface of the bent pipe.

[0046] The third embodiment: Figure 3 , Figure 6 As shown, a thread lifter 72 is fixedly connected to the edge of the surface of the slide cylinder 71, an inner side surface of the thread lifter 72 is threadedly connected to an inner thread block 73, an inner side surface of the inner thread block 73 is fixedly connected to a telescopic motor 74, an output end of the telescopic motor 74 is fixedly connected to a driving component 76, and an inner side surface of the driving component 76 is rotatably connected to a clamping component 77;

[0049] When in use, the clamping assembly 77 firmly clamps the outer surface of the bent pipe, the threaded lifter 72 controls the overall lifting and lowering of the driving assembly 76, the telescopic motor 74 controls the overall angular deflection of the driving assembly 76, the sliding cylinder 71 moves horizontally on the surface of the guide slide 2, the horizontal and height positions of the clamping assembly 77 change while the inclination angle of the axis changes, so that the inner side surface of the clamping assembly 77 can always fit closely with the surface of the bent pipe, so that the clamping assembly 77 can clamp different positions on the surface of the bent pipe, the electric turntable 82 is used to control the overall rotation of the lubrication assembly 84, the hydraulic cylinder 81 controls the overall lifting and movement of the lubrication assembly 84, and the grinding The surface of the wheel 87 is arranged tangent to the surface of the bent pipe. The adjustment of the hydraulic cylinder 81 and the electric turntable 82 makes the grinding wheel 87 always tangent to the surface of the bent pipe, driving the motor 86 to drive the grinding wheel 87 to rotate, and the grinding wheel 87 polishes the surface of the bent pipe. The lubrication component 84 transports the polishing paste to the surface of the grinding wheel 87 to lubricate it. The atomization component 85 promotes the lubrication effect of the polishing paste. The drive component 76 makes the clamping component 77 rotate slowly around the core shaft. The protective plate 9 is arranged directly below the grinding wheel 87 to guide a small amount of lubricating liquid, which solves the problem that the poor lubrication effect of water during the polishing process easily leads to an uneven surface of the flattening roller.

[0050] Fourth embodiment: Figure 6-Figure 9 As shown, the lubrication assembly 84 includes a cutting shell 841, the lower position of the surface of the cutting shell 841 is fixedly installed on the end surface position of the extension rod 83, and the top of the cutting shell 841 is fixedly connected to the cylindrical shell 842.

[0051] When in use, water is often used in the prior art to lubricate the grinding wheel 87, but the poor lubrication effect of water will result in the surface of the bent pipe being unable to be polished. In this device, the injection pipe 844 is used to squeeze the polishing paste into the interior of the eccentric tube 843, and the screw conveyor 845 drives the polishing paste to be squeezed and conveyed to the interior of the cylindrical shell 842. The eccentric tube 843 and the reduction motor 88 are arranged opposite to each other and are eccentrically installed on the surface of the cylindrical shell 842.

As the reduction motor 88 drives the rotating roller 89 to rotate, the rotating roller 89 applies the polishing paste to the surface of the grinding wheel 87. The water spraying direction of the atomizing nozzle 853 is set tangentially to the surface of the grinding wheel 87. The surface of the grinding wheel 87 is coated with polishing paste and then sprayed with water. Compared with using water alone for lubrication, this method makes the polishing effect of the bent pipe better.

The clamping assembly 77 also includes a second half wheel 773, which is rotatably mounted on the inner side of the housing 761. A straight hole 774 is opened on the surface of the second half wheel 773. The inner sides of the first half wheel 771 and the second half wheel 773 are both fixedly connected to a rubber half tube 775.

[0054] The lower position of the surface of the cutting shell 841 is fixedly installed on the end surface position of the extension rod 83, and the top of the cutting shell 841 is fixedly connected to the cylindrical shell 842. The lubrication assembly 84 also includes an eccentric tube 843, and the end surface position of the eccentric tube 843 is eccentrically fixed on the surface of the cylindrical shell 842.

The polishing paste is extruded and transported by the screw conveyor 845. When the polishing paste is squeezed into the internal cavity of the cylindrical shell 842, the air inside the polishing paste is discharged downward, making the polishing paste on the surface of the rotating roller 89 more dense. As the rotating roller 89 rotates, the polishing paste is evenly coated on the surface of the grinding wheel 87. Water is stored in the water storage tank 851, and the atomized water of the atomizing nozzle 853 makes The polishing paste has better fluidity when lubricated, and the inner sides of the first half wheel 771 and the second half wheel 773 firmly clamp the surface of the curved pipe.

When the first half wheel 771 and the second half wheel 773 clamp the curved pipe near the edge, the grinding wheel 87 polishes the curved pipe near the middle. When the grinding wheel 87 polishes the edge of the curved pipe, the shell 761 moves to the position near the middle of the curved pipe to clamp it, so that the surface of the curved pipe is polished.
