Description

Technical Field

[0001] The present invention relates to the technical field of grinding, and particularly to a pipe grinding device. Background Art

[0002] Grinding refers to the process of grinding and polishing the surface of an object by using tools or machinery, aiming to make the surface of the object smooth and delicate. This process can be applied to a variety of materials, including stone, metal and other materials, as well as other items that need to improve the surface texture. The basic purpose of grinding is to remove the defects and uneven parts on the surface of the object through physical or chemical methods, while increasing the smoothness and brightness of the surface. In specific applications, grinding can not only be used to beautify the appearance, but also enhance the physical properties of materials, such as improving the wear resistance and anti-slip properties of materials. At present, many components are processed from pipe fittings, and many pipe fitting raw materials need to be ground by using grinding equipment during processing.

[0003] When the existing grinding equipment grinds pipe fittings, it is necessary to first clamp the pipe fittings, then drive the pipe fittings to rotate, and then drive the grinding wheel to rotate, translate and lift to grind the pipe fittings. This kind of grinding equipment usually sets a driving element for driving in one movement direction, which will cause multiple driving elements to be used in cooperation to complete the processing. This kind of grinding equipment has more driving elements, resulting in higher production costs and higher failure rates. Moreover, the existing grinding equipment cannot grind the end face of the pipe fitting while grinding the outer cylindrical surface of the pipe fitting, and another grinding equipment needs to be used to grind the end face of the pipe fitting, which is rather cumbersome. For this reason, we have proposed a pipe grinding device to solve the above problems. Summary of the Invention

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0033] Refer to Figures 1 to 12, A pipe grinding device, comprising a processing table 1. Several support legs are fixedly arranged on the lower side of the processing table 1, and the number of support legs is eight. An automatic processing component and a positioning component are arranged on the upper side of the processing table 1. The positioning component is located on one side of the automatic processing component. Before grinding the pipe fitting, it is necessary to use the positioning component to position the pipe fitting, and then the pipe fitting is ground by the automatic processing component. The positioning component includes a fixed support component and a pressing and clamping component. The fixed support component is used to support the pipe fitting. The fixed support component includes two support rollers 22. The two support rollers 22 are at the same horizontal height, and the diameters of the two support rollers 22 are the same. Two support seats 23 are rotatably arranged on the outer periphery of the support roller 22, and the support seats 23 are fixed on the upper side of the processing table 1. A first retaining ring 24 is fixedly arranged on the outer periphery of the support roller 22. Before processing the pipe fitting, the pipe fitting needs to be placed on the two support rollers 22. At this time, the pipe fitting will contact the support rollers 22 and be located above the space between the two support rollers 22, and one end of the pipe fitting needs to be abutted against the first retaining ring 24. Several slag falling annular grooves 25 are arranged on the outer periphery of the support roller 22. During processing, the generated waste slag will fall into the slag falling annular grooves 25, so that a large amount of waste slag will not adhere to the outer periphery of the support roller 22, thus ensuring the stability of the pipe fitting during processing. A material blocking component is arranged on one support roller 22. The material blocking component includes a second retaining ring 26. During the placement of the pipe fitting, the other end of the pipe fitting needs to be abutted against the second retaining ring 26, so that the pipe fitting is restricted between the second retaining ring 26 and the first retaining ring 24, thus ensuring that the pipe fitting will not move left and right during processing. The second retaining ring 26 slides on the outer periphery of the support roller 22. A long groove is arranged on the inner wall of the second retaining ring 26. A stepped hole is arranged on the outer periphery of the second retaining ring 26, and the stepped hole is communicated with the long groove. A locking bolt 28 is rotatably arranged inside the stepped hole. A locking piece 27 is threadedly connected to the outer periphery of the locking bolt 28. The locking piece 27 slides inside the long groove, and the locking piece 27 contacts the outer periphery of the support roller 22. Before placing the pipe fitting, it is necessary to adjust the position of the second retaining ring 26 according to the length of the pipe fitting. When adjusting the position of the second retaining ring 26, it is necessary to first use a sleeve tool to turn the locking bolt 28 so that the locking piece 27 moves away from the support roller 22. At this time, the second retaining ring 26 can be slid to adjust. After the position adjustment of the second retaining ring 26 is completed, the locking bolt 28 is rotated again so that the locking piece 27 presses tightly against the support roller 22. At this time, the position of the second retaining ring 26 can be locked. It can be adjusted according to the length of the pipe fitting to meet various usage requirements.

[0034] Such as Figures 1 to 3 , Figure 9As shown, the downward pressing and clamping assembly is used to press the pipe fitting. The downward pressing and clamping assembly includes a lifting plate 29. One side of the lifting plate 29 is slidably provided with an adjusting plate 30. The lifting plate 29 and the adjusting plate 30 are slidably connected through a slide rail, and the lifting plate 29 and the adjusting plate 30 are detachably connected by bolts. A number of inclined U-shaped hollow frames 31 are fixedly provided on the side of the adjusting plate 30 away from the lifting plate 29. A pressing wheel 32 is rotatably provided inside the inclined U-shaped hollow frame 31. The lifting plate 29 is located above the processing table 1. During the positioning of the pipe fitting, after the pipe fitting is placed on the support roller 22, it is also necessary to lower the lifting plate 29 and the pressing wheel 32 so that the pressing wheel 32 presses the pipe fitting. At this time, the positioning of the pipe fitting can be completed. Before use, the height of the adjusting plate 30 needs to be adjusted. When the height of the adjusting plate 30 needs to be adjusted, the bolts between the lifting plate 29 and the adjusting plate 30 need to be loosened first, and then the adjusting plate 30 is slid up and down. After the adjustment is completed, the bolts between the lifting plate 29 and the adjusting plate 30 need to be tightened to lock the position of the adjusting plate 30, so as to be applicable to pipe fittings of different diameters and can press and position pipe fittings of different diameters.

[0035] As Figure 4 、 Figure 6As shown, the automatic processing component includes a grinding component, a lifting component, and a translation component. The grinding component is used for grinding pipe fittings. The grinding component is used to drive the pipe fittings to rotate. The translation component is used to drive the lifting component. The grinding component is connected to the lifting component, and the translation component is connected to the lifting component. The grinding component includes an adjustment frame 2. The adjustment frame 2 is an L-shaped structure. Two outer support plates 3 and two inner support plates 4 are fixedly provided on the lower side of the top of the adjustment frame 2. The inner support plate 4 is located between the two outer support plates 3. A driving shaft 5 is provided below the adjustment frame 2. Two driving shafts 7 are provided below the driving shaft 5. A grinding shaft 6 is provided between the two driving shafts 7. The grinding shaft 6 is located directly below the driving shaft 5. Two through holes are provided on one side of the inner support plate 4. The driving shaft 5 and the grinding shaft 6 rotate inside the through holes. One end of the driving shaft 5 rotates on one side of the outer support plate 3. A through hole is provided on one side of the outer support plate 3. The driving shaft 7 rotates inside the through hole. A processing motor 8 is fixedly provided on one side of an outer support plate 3. The processing motor 8 is externally connected to a power source and a switch through a wire. The shaft end of the processing motor 8 is connected to the outer circumference of the driving shaft 5 through bevel gear transmission. A transmission component is provided between the driving shaft 5 and the driving shafts 7 and the grinding shaft 6. The transmission component makes the rotation direction of the driving shaft 7 opposite to the rotation direction of the grinding shaft 6. Specifically: The outer circumference of the driving shaft 5 is connected to the outer circumference of the driving shaft 7 through gear transmission. The outer circumference of the driving shaft 5 is connected to the outer circumference of the grinding shaft 6 through belt and pulley transmission. A grinding wheel 9 is fixedly provided on the outer circumference of the grinding shaft 6. The grinding wheel 9 is located between the two inner support plates 4. A driving wheel 10 is fixedly provided on the outer circumference of the driving shaft 7. A flexible ring 11 is fixedly provided on the outer circumference of the driving wheel 10. The diameter of the flexible ring 11 is larger than the diameter of the grinding wheel 9. The diameter of the flexible ring 11 is only slightly larger than the diameter of the grinding wheel 9. The outer support plate 3 is located between the two flexible rings 11. When it is necessary to grind and process the pipe fittings, it is necessary to turn on the processing motor 8. After the processing motor 8 is turned on, it will drive the driving shaft 5 to rotate. The driving shaft 5 will drive the grinding shaft 6 and the driving shafts 7 to rotate. Moreover, the rotation direction of the driving shaft 7 is opposite to the rotation direction of the grinding shaft 6. Therefore, the rotation direction of the driving wheel 10 is opposite to the rotation direction of the grinding wheel 9. During the grinding of the pipe fittings, it is necessary to make the flexible ring 11 closely adhere to the pipe fittings. At this time, the flexible ring 11 will deform, and the pipe fittings will also rotate together with the flexible ring 11. At the same time, the grinding wheel 9 will also contact the pipe fittings for grinding. Therefore, the processing motor 8 can drive the pipe fittings to rotate and the grinding wheel 9 to rotate.

[0036] As Figure 1 , Figure 7 , Figure 8As shown, the translation component is used to drive the grinding component and the lifting component to perform translational motion. The translation component includes a moving seat 18, and the moving seat 18 is of an L-shaped structure. A moving motor 19 is fixedly provided on the upper side of the bottom of the moving seat 18. The moving motor 19 is externally connected to a power supply and a controller through a wire. A moving gear 20 is fixedly provided at the shaft end of the moving motor 19. A moving rack 21 is fixedly provided on the upper side of the processing table 1. The moving gear 20 is in transmission connection with the moving rack 21 through meshing. The moving seat 18 slides on the upper side of the processing table 1. During the grinding of the pipe fitting, it is necessary to make the grinding wheel 9 translate while rotating, so that the pipe fitting can be continuously ground. When the grinding wheel 9 needs to be translated, it is necessary to control the rotation of the moving motor 19. When the moving motor 19 rotates, it will drive the moving seat 18 to translate through the moving gear 20 and the moving rack 21. When the moving seat 18 translates, it will drive the adjusting frame 2 and the grinding wheel 9 to translate together through the lifting component, so that the pipe fitting can be automatically and continuously ground.

[0037] As Figure 5 , Figure 7 , Figure 8 , Figure 10 As shown, the lifting component is used to drive the grinding component to perform lifting motion. The lifting component includes a lifting frame 12, and the lifting frame 12 is of an inverted L-shaped structure. The moving seat 18 slides on the outer periphery of the lifting frame 12. A first threaded hole is provided on the upper side of the lifting frame 12. An adjusting bolt 13 is provided inside the first threaded hole through threaded connection. The lower end of the adjusting bolt 13 rotates on the upper side of the adjusting frame 2. The adjusting frame 2 slides on one side of the lifting frame 12. A locking nut 14 is provided on the outer periphery of the adjusting bolt 13 through threaded connection. The locking nut 14 is in contact with the upper side of the lifting frame 12. A long hole is provided on the upper side of the processing table 1. The lifting frame 12 slides inside the long hole. A driving wheel 15 is rotatably provided on one side of the lifting frame 12. A driving frame 16 is fixedly provided on the lower side of the processing table 1. A driving groove 17 is provided on one side of the driving frame 16. The driving groove 17 is of a structure with a flat middle, inclined ends and a height higher than the middle position. The driving wheel 15 slides inside the driving groove 17. During the grinding of the pipe fitting, it is necessary to make the grinding wheel 9 descend to contact the pipe fitting. Specifically, before processing, it is necessary to make the lifting frame 12 at one end of the long hole, and then control the rotation of the moving motor 19 to make the lifting frame 12 translate to the other end of the long hole. During the translation of the lifting frame 12, the driving wheel 15 will slide inside the driving groove 17. Therefore, during the translation of the lifting frame 12, it will first descend and then continue to move horizontally. When it is about to move to the other end of the long hole, the lifting frame 12 will rise, so as to drive the lifting frame 12, the grinding wheel 9 and the adjusting frame 2 to automatically lift. Before processing, it is necessary to adjust the height of the adjusting frame 2 according to the diameter of the pipe fitting. When it is necessary to adjust the height of the adjusting frame 2, the adjusting frame 2 can be moved up or down by rotating the adjusting bolt 13. After the adjustment is completed, it is necessary to tighten the locking nut 14 to lock the height of the adjusting bolt 13.

[0038] As Figure 3 , Figure 5 , Figure 7 , Figure 9 shown, the lifting assembly is used to drive the pressing and clamping assembly to lift and press down. A driving track 33 is provided on the lower side of the processing table 1. The cross-section of the driving track 33 is a U-shaped structure. A plurality of guide rods 34 are fixedly provided on one side of the lifting plate 29. The lower ends of the guide rods 34 are fixedly arranged on the upper side of the driving track 33. A plurality of guide holes are provided on the upper side of the processing table 1. The guide rods 34 slide inside the guide holes. A driving frame 35 is fixedly provided on one side of the lifting frame 12. A plurality of connecting wheels 36 are rotatably provided on one side of the driving frame 35. The connecting wheels 36 slide inside the driving track 33. The connecting wheels 36 are in contact with the inner side of the driving track 33. When the pipe fitting is clamped between the two support rollers 22 and the pressing wheel 32, the circumferential angle gap between the pressing wheel 32 and the support roller 22 is less than 180 degrees (with the center of the pipe fitting as the center, the point where the pressing wheel 32 contacts the pipe fitting, and the point where the support roller 22 contacts the pipe fitting. The circumferential angle formed by these three points needs to be determined according to the adjacent pressing wheel 32 and support roller 22). Before grinding the pipe fitting, it is necessary to lower the lifting plate 29 to press the pipe fitting through the pressing wheel 32. During processing, the lifting frame 12 will move from one end of the long hole to the other end. When the lifting frame 12 moves horizontally, it will drive the lifting frame 12 to rise or fall. When the lifting frame 12 moves up and down, it will drive the lifting plate 29 to move up and down together through the driving frame 35, connecting wheels 36, driving track 33 and guide rods 34, so as to achieve one driving multiple. A single driving element can drive multiple movement directions. It should be noted that during processing, it is necessary to first press the pipe fitting through the pressing wheel 32, and then make the flexible ring 11 and the grinding wheel 9 contact the pipe fitting in sequence for processing.

[0039] As Figure 4 , Figure 10 shown, a first end face grinding assembly is provided on the upper side of the processing table 1. The first end face grinding assembly is used to grind the end face of the pipe fitting. The first end face grinding assembly includes a sliding frame 37. The sliding frame 37 slides on the upper side of the processing table 1. A tension spring 38 is fixedly arranged between one side of a support seat 23 and one side of the sliding frame 37. A first grinding piece 39 is fixedly provided on one side of the sliding frame 37. A plurality of first chamfers are provided on one side of the first grinding piece 39. When the pipe fitting is placed on the support roller 22, one end of the pipe fitting will contact the first grinding piece 39, and the first grinding piece 39 will be attached to the end face of the pipe fitting due to the pulling force of the tension spring 38. While the flexible ring 11 drives the pipe fitting to rotate, the first grinding piece 39 will grind one end face of the pipe fitting, so as to automatically grind the end face.

[0040] As Figure 2 , Figure 12As shown in the figure, a second end face grinding assembly is provided on one side of the downward pressing and clamping assembly. The second end face grinding assembly is used to grind the other end face of the pipe fitting. The second end face grinding assembly includes an inverted U-shaped bending frame 40. A groove is provided at one end of the inverted U-shaped bending frame 40. A square rod 41 is fixedly provided inside the groove. A sliding piece 42 is slidably provided on the outer periphery of the square rod 41. A plurality of springs 43 are fixedly provided between one side of the sliding piece 42 and the inner side of one side of the groove. A mounting seat 44 is fixedly provided on one side of the sliding piece 42. A second grinding piece 45 is fixedly provided on one side of the mounting seat 44. A plurality of second chamfers are provided on one side of the second grinding piece 45. The second grinding piece 45 will rise and fall together with the lifting plate 29. When the lifting plate 29 descends to position the pipe fitting, the second grinding piece 45 will also descend. Thus, the second grinding piece 45 can automatically descend and contact the other end face of the pipe fitting, and will adhere to the other end face of the pipe fitting due to the tension of the spring 43. While the flexible ring 11 drives the pipe fitting to rotate, the second grinding piece 45 will grind the other end face of the pipe fitting. Thus, the two end faces of the pipe fitting can be automatically ground. When the second grinding piece 45 descends, the second chamfers can enable the second grinding piece 45 to smoothly adhere to the other end face of the pipe fitting. A cross-shaped hole is provided on one side of the inverted U-shaped bending frame 40. A cross-shaped block 46 is slidably provided inside the cross-shaped hole. An adjusting block 47 is fixedly provided on one side of the cross-shaped block 46. The adjusting block 47 slides on one side of the lifting plate 29. A connecting hole is provided on one side of the cross-shaped block 46. An L-shaped clamping frame 48 is slidably provided inside the connecting hole. A second threaded hole is provided on one side of the L-shaped clamping frame 48. A clamping bolt 49 is threadedly connected inside the second threaded hole. A U-shaped clamping seat 50 is slidably provided on one side of the inverted U-shaped bending frame 40.

When it is necessary to adjust the height and position of the inverted U-shaped bending frame 40, it is necessary to loosen the clamping bolt 49. At this time, the adjusting block 47 can be slid to adjust the position of the inverted U-shaped bending frame 40, and the height of the inverted U-shaped bending frame 40 can also be adjusted by moving the inverted U-shaped bending frame 40 up and down. After the adjustment is completed, it is necessary to tighten the clamping bolt 49. At this time, the inverted U-shaped bending frame 40, the cross-shaped block 46, the adjusting block 47 and the lifting plate 29 will be clamped between the L-shaped clamping frame 48 and the U-shaped clamping seat 50. Therefore, the inverted U-shaped bending frame 40 will be locked.
