Description

Technical Field

[0001] This utility model belongs to the technical field of ultra-precision machining equipment, specifically relating to a polishing and feeding device suitable for pipes of different diameters. Background Technology

[0002] Round tube polishing equipment is widely used in industries such as machinery and chemicals. Its working principle is to reduce the surface roughness of the workpiece using abrasive belts or polishing heads, obtaining a bright and smooth surface. During operation, a feeding device should be placed in front of the round tube polishing equipment so that the tube gradually enters the main unit as it rotates, eliminating the need for manual support by the operator, reducing labor intensity, and improving work efficiency. However, several problems have been found in actual use:

[0003] 1. If there are impurities on the pipe surface or the thin-walled steel pipe is bent, the pipe will jump in the feeding equipment. Furthermore, thin-walled steel pipes cannot be subjected to excessive pressure, resulting in poor polishing results.

[0004] 2. Pipes of different diameters require machine shutdown and debugging, which reduces work efficiency.

[0005] 3. The existing feeding mechanism cannot accommodate pipes of 16-108mm. Currently, the market only offers pipes of 16-50mm or 50-133mm, which is very inconvenient in actual operation. Utility Model Content

[0038] As shown in the figure, the present invention provides a polishing and feeding device for pipes of different diameters, comprising a base 1, a waiting area 2, a vibration area 3, a waiting zone 4, and a working area 5.

[0039] The waiting area 2 includes a rotating support 6, a lifting frame 7, a cylinder 1 8, and a cylinder 2 9. Two baffles 10 are provided at the junction of the waiting area 2 and the vibration area 3. The lifting frame 7 is located between the two baffles 10. The two rotating supports 6 are movably mounted at both ends of the base 1. The cylinder 1 8 and the cylinder 2 9 are mounted on the base 1. The cylinder 1 8 is connected to the rotating support 6, and the cylinder 2 9 is connected to the lifting frame 7.

[0040] Vibration zone 3 includes a vibration frame 11, a vibration motor 12, a support frame 13, and a cylinder 14. The vibration frame 11 is mounted on the base 1, and a spring 15 is provided on the back of the upper surface of the vibration frame 11. The vibration motor 12 is located below the vibration frame 11, and two support frames 13 are located at both ends of the vibration frame 11. The cylinder 14 is connected to the support frame 13.

[0041] The waiting area 4 includes a tilting frame 16, a limiting frame 17, a stop block 18, and a cylinder 19. The two tilting frames 16 are located at both ends of the waiting area 4. The height of the tilting frame 16 is higher than the height of the vibration frame 11. The limiting frame 17 is located above the tilting frame 16 (with a gap between them). The limiting frame 17 is equipped with an adjusting handwheel 20. The limiting frame 17 is fixed to the outside of the base 1 by a bracket. The two stop blocks 18 are located on the outside of the tilting frame 16. The cylinder 19 is connected to the bottom of the tilting frame 16.

[0042] The working area 5 includes a motor mounting bracket 21, a rotary motor 22, a first row of rollers 23, a second row of rollers 24, a lifting frame 25, cylinder 5 26, cylinder 6 27, cylinder 7 28, and cylinder 8 29. The lifting frame 25 is movably mounted on the base 1. The first row of rollers 23 is fixed to the lifting frame 25, and the second row of rollers 24 is movably mounted on the lifting frame 25. The first row of rollers 23 and the second row of rollers 24 are arranged parallel to each other, and the rollers on the first row of rollers 23 and the second row of rollers 24 are horizontally inclined at 10-40°. Cylinder 5 26 is connected to lifting frame 25, cylinder 7 28 is connected to second row of rollers 24, motor fixing frame 21 is fixed on the outside of base 1, and slider 30 is provided on the side of motor fixing frame 21. Rotary motor 22 is set on slider 30, cylinder 8 29 is connected to rotary motor 22, rotary motor 22 is connected to disc elastic pressure head 31, disc elastic pressure head 31 is set above first row of rollers 23 and second row of rollers 24, and movable seat 32 is provided on the bottom surface of motor fixing frame 21. Cylinder 6 27 is connected to movable seat 32.

[0043] The base 1 of this utility model is a frame structure welded from angle steel and iron bars, which is stable and reliable. An adjusting nut is provided at the bottom to ensure that the base remains in a horizontal state.

[0044] During operation, cylinder 8 lowers, suspending the bundled pipes onto the rotating support 6. Then, cylinder 8 is activated, raising the rear end of the rotating support 6. At this point, the pipes are blocked at the front by two baffles 10, cutting the sheet metal binding the pipes and dispersing them. Next, cylinder 9 is activated, lifting the lifting frame 7 over the baffles 10, causing some pipes to roll onto the vibrating frame 11. The vibrating motor 12 then starts, laying the pipes flat (without stacking them). Then, cylinder 14 is activated, lifting the support frame 13. Because the upper surface of the support frame 13 is inclined, when the height of the support frame 13 exceeds the tilt frame 16, the pipes will actively roll towards the tilt frame 16. The height between the upper limit frame 17 and the tilt frame 16 can be adjusted using the adjusting handwheel 20 to ensure that pipes of various diameters can be accommodated. Figure 9As shown, an elongated hole 33 is provided below the stop 18 to adjust the extension length of the stop 18, ensuring that only one tube can enter the waiting area at a time, while the others must remain on the lifting frame 13. Then, cylinder 4 19 is activated to lift the tilting frame 16. After passing the stop 18, the tube 37 will fall between the first row of rollers 23 and the second row of rollers 24. Cylinder 8 20 is activated to adjust the height of the disc elastic pressure head 31, gently pressing the tube 37 from above. The rotary motor 22 rotates, driving the tube 37 along the tilting rollers. The forward movement of the rollers can restrict the cylindrical runout of the pipe in all directions. During this process, there are three adjustments: cylinder 5 26 can raise and lower the rollers through the lifting frame 25; cylinder 6 27 can move the disc elastic pressure head 31 left and right through the moving seat 32 to ensure that the disc elastic pressure head 31 presses the radial center point of the pipe; and cylinder 7 28 can drive the second row of rollers 24 to move left and right to adjust the distance between the two rows of rollers. This not only adapts to pipes of different diameters, but also ensures that the pipe enters the polishing machine horizontally and straight.

[0045] This utility model has a novel structure. The pipe passes through a waiting area, a vibration area, a waiting zone, and a working area. The operation is fully intelligent, and the feeding is convenient and fast. Moreover, only one pipe can be put into the waiting area at a time. The workflow is clear and will not cause confusion or errors.

[0046] This utility model has a scale 34 on the limiting frame 17, so that you know how much to move when adjusting, which is convenient and quick.

[0047] The present invention provides a limiting strip 35 on the outer side of the base 1 to prevent the pipe 37 from rolling off when it falls from the inclined frame 16.

[0048] The present invention describes a motor mounting bracket 21 consisting of two brackets, located at both ends of the outer side of the base 1, with an auxiliary bracket in the middle. A long tube is held in place by three round elastic pressure heads 31, preventing it from jumping out.

[0049] The roller of this utility model has an arc-shaped adjustment hole 36 on its fixed support, such as... Figure 10 As shown, the angle can be adjusted according to the diameter of the pipe to ensure that the pipe can move forward smoothly.

[0050] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
