[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In one embodiment, see Figure 1-Figure 9 , a steel burr grinding equipment, including a fixed base 1 and a transverse base 2 with adjustable spacing, the fixed base 1 on the left and the transverse base 2 on the right are both placed horizontally and can be placed directly on the ground, and guide columns 5 arranged in a left-right direction are slidably connected to the front and rear sides of the right side of the fixed base 1, the right end of the guide column 5 is fixedly connected to the left side of the transverse base 2, and the middle part of the transverse base 2 is rotatably connected to a transverse screw rod 6 arranged in a left-right direction, and the left side of the transverse screw rod 6 is threadedly connected to the right side of the fixed base 1, so the spacing between the transverse base 2 and the fixed base 1 can be adjusted by rotating the transverse screw rod 6, so as to realize effective grinding of metal pipes 12 of different lengths, and also includes a material fixing mechanism 3 and a grinding mechanism 4; The material fixing mechanism 3 is provided with first columns 7 vertically on both the front and rear sides of the right end of the upper surface of the fixed base 1 and the front and rear sides of the left end of the upper surface of the traverse base 2. The upper end of the first column 7 is fixedly connected to a discharge plate 10 arranged in a front-to-back direction. Both the front and rear ends of the upper surface of the discharge plate 10 are rotatably connected to discharge wheels 11. Therefore, the metal tube 12 can be placed on the discharge wheel 11 in a left-right direction. The left and right sides of the metal tube 12 are respectively placed between the front and rear discharge wheels 11, so that the metal tube 12 can be kept horizontal and placed in the center. The grinding mechanism 4 includes a second column 22 vertically arranged on the front and rear sides of the left end of the upper surface of the fixed base 1, a lifting seat 23 is slidably connected to the upper side of the second column 22, a fixed block 33 is arranged on the left side of the lifting seat 23, and the fixed block 33 is threadedly connected to a vertically arranged lifting screw 34, the upper end of the lifting screw 34 is rotatably connected to the left side of the top plate 35, and the right side of the top plate 35 is fixedly connected to the upper end of the second column 22, and winding wheels 24 are rotatably connected to the front and rear sides of the right side of the lifting seat 23, and the front and rear winding wheels 24 are respectively wound and connected to the two ends of the pulling belt 20. When the two winding wheels 24 rotate at the same time, one of the winding wheels 24 winds up the pulling belt 20, and the other winding wheel 24 releases the pulling belt 20, so that the pulling belt 20 is transferred from one winding wheel 24 to the other winding wheel 24, and is fixedly connected in the middle of the pulling belt 20. The grinding head 21 has a through hole 29 on one side of the grinding head 21, so that the pulling belt 20 can pass through the through hole 29. As shown in the accompanying drawings, the pulling belt 20 on the rear side is fixedly connected to the through hole 29, and the pulling belt 20 on the front side passes through the through hole 29 from right to left, so that the pulling belt 20 can drive the grinding head 21 to move left and right when it moves. A lifting plate 17 is slidably connected under the first upright column 7 on the right side, and the middle part of the lifting plate 17 is fixedly connected to the left end of the extension frame 18, and the right end of the extension frame 18 is extended upward. The right end part of the extension frame 18 is slidably connected to the tensioning slide bar 27 arranged in the left and right directions, and the left end of the tensioning slide bar 27 is fixedly connected to the tensioning frame 28. The tensioning frame 28 is rotatably connected to the tensioning pulley 19, and the tensioning pulley 19 can press against one side of the pulling belt 20, so that the pulling belt 20 can remain in a tensioned state during work. When the pulling belt 20 is tightened under normal conditions, the tensioning pulley 19 will be at the same height as the winding wheel 24 on the left, or a damping device can be provided inside the lifting plate 17 so that after the operator drives the lifting plate 17 to move up and down along the second column 22, the lifting plate 17 can stay in this position, thus achieving the effect of the operator actively adjusting the height of the tensioning pulley 19.

[0026] In one case of this embodiment, the axis lines of the four unloading wheels 11 are at the same height and are arranged in parallel, and a clamping assembly 16 for pressing the metal tube 12 onto the unloading wheel 11 is arranged on the first column 7 . The clamping assembly 16 includes a support plate 8 slidably connected to the first column 7, the support plate 8 is arranged in a front-to-back direction, a buffer spring 9 is arranged between the support plate 8 and the discharge plate 10, and the buffer spring 9 is sleeved on the outside of the first column 7, so the buffer spring 9 will push the support plate 8 downward to achieve the effect of clamping force, and the front and rear ends of the support plate 8 are fixedly connected to the clamping frame 13, the clamping frame 13 is a U-shaped structure with an opening downward, and the middle part of the upper end of the clamping frame 13 is rotatably connected with a clamping wheel 14, and the clamping wheel 14 moves downward under the action of the buffer spring 9, so the clamping wheel 14 will press the metal tube 12 downward, so that the metal tube 12 is tightly pressed on the discharge wheel 11, achieving the fixing effect of the metal tube 12, and a rotation drive motor 15 is arranged on the left side of the clamping frame 13, and the rotation drive motor 15 can drive the clamping wheel 14 to rotate, thereby realizing the rotation of the metal tube 12, so that the grinding head 21 can effectively grind different positions of the inner wall of the metal tube 12.

[0027] In one case of the present embodiment, a winding motor 32 is arranged at the lower front side of the lifting seat 23, and the output shaft of the winding motor 32 is connected to the lower end of the front winding wheel 24, and the front winding wheel 24 is driven to rotate by the winding motor 32, and a synchronous rotation component 42 is arranged above the lifting seat 23. When the synchronous rotation component 42 is working, the front and rear winding wheels 24 will rotate synchronously, but when the synchronous rotation component 42 is disconnected and not working, only the front winding wheel 24 will work under the drive of the winding motor 32. The synchronous rotation component 42 includes a synchronous pulley 41 fixed to the upper end of the winding wheel 24, and a push-pull bracket 38 is slidably connected above the left side of the lifting seat 23. The push-pull bracket 38 can slide left and right. A push block 36 is set on the lower surface of the push-pull bracket 38. The push block 36 is threadedly connected to a push-pull screw rod 37 set in the left and right directions. The right end of the push-pull screw rod 37 is rotatably connected to the left side of the lifting seat 23, so that the left and right movement of the push-pull bracket 38 is controlled by the push-pull screw rod 37, and the push-pull bracket 38 is rotated. The push-pull pulley 39 and the two synchronous pulleys 41 are sleeved inside the same drive belt 40. Therefore, when the push-pull pulley 39 moves to the left, the drive belt 40 is tightened. At this time, the synchronous pulley 41 and the push-pull pulley 39 will rotate synchronously. However, when the push-pull pulley 39 moves to the right, the drive belt 40 is in a relaxed state. At this time, the synchronous pulley 41 will not rotate with the push-pull pulley 39, and the front and rear winding wheels 24 can rotate separately.

[0028] In one case of the present embodiment, in order to allow the pulling belt 20 to pass through the metal pipe 12 better, guide brackets 30 are provided at the front and rear ends of the right side of the lifting seat 23. The guide bracket 30 is an L-shaped structure extending toward the center direction of the lifting seat 23. A guide head 31 is provided at the end of the guide bracket 30. The guide head 31 will push the pulling belt 20 toward the center, so that the front and rear pulling belts 20 are close to each other and remain in a straight state to extend into the inside of the metal pipe 12. The distance between the front and rear guide heads 31 is just the diameter of the right tensioning pulley 19, and a through hole 29 is provided on the front side of the grinding head 21, so that the pulling belt 20 can pass through the through hole 29 from right to left, so that when the pulling belt 20 moves, only the pulling belt 20 on the rear side will drive the grinding head 21 to move.

[0029] During the implementation of this embodiment, the transverse screw rod 6 is rotated to adjust the distance between the fixed base 1 and the transverse base 2 so that the distance between the discharge wheels 11 on the left and right sides meets the length of the metal tube 12. The clamping frame 13 on the right side is lifted, and the metal tube 12 is inserted from right to left between the clamping wheel 14 on the right and the discharge wheel 11. The operation is repeated to insert the metal tube 12 from right to left between the discharge wheel 11 on the left and the clamping wheel 14. At this time, the metal tube 12 is fixed.

[0030] The height of the lifting seat 23 is adjusted by the lifting screw rod 34, and the height of the tensioning pulley 19 is adjusted so that the winding wheel 24 and the tensioning pulley 19 are both at the same height as the axis of the metal tube 12. At this time, one end of the pulling belt 20 is fixed on the rear winding wheel 24, and the grinding head 21 is placed inside the left side of the metal tube 12, and the left end of the metal tube 12 is lifted. Under the action of gravity, the grinding head 21 slides to the right along the inner wall of the metal tube 12, and the grinding head 21 slides to the right side of the metal tube 12 along the metal tube 12 and is exposed, the grinding head 21 is taken out, and the other end of the pulling belt 20 is passed through the tensioning pulley 19 from back to front, and passed through The grinding head 21 is put into the metal tube 12 again through the through hole 29 on the front side of the grinding head 21, and the right end of the metal tube 12 is lifted. The grinding head 21 slides out to the left along the inside of the metal tube 12, and the grinding head 21 slides to the left side of the metal tube 12 with the pulling belt 20. At this time, the free end of the pulling belt 20 is pulled out and fixed on the winding wheel 24 on the front side, and the winding motor 32 is started. The winding wheel 24 on the front side winds the pulling belt 20, thereby tightening the pulling belt 20. At this time, the tensioning spring 26 is stretched, and the height of the winding wheel 24 and the tensioning belt wheel 19 are adjusted so that the grinding head 21 is close to the top of the inner wall of the metal tube 12, and the grinding head 21 is installed.

[0031] The push-pull screw rod 37 is rotated to tighten the driving belt 40. At this time, the driving winding motor 32 is continuously reversed. The pulling belt 20 is continuously reversed from a top view, so that the grinding head 21 continuously moves left and right on the inner wall of the metal tube 12. The inner wall of the metal tube 12 is continuously polished by the grinding head 21. In the process of polishing, the rotating driving motor 15 can also be started to make the metal tube 12 rotate itself, so that the inner wall of the metal tube 12 is completely polished.

[0032] After grinding is completed, the driving belt 40 is loosened, the pulling belt 20 is released through the winding wheel 24 on the front side, and the left end of the metal tube 12 is lifted, so that the grinding head 21 slides to the right along the metal tube 12, and the pulling belt 20 is pulled out from the through hole 29 of the grinding head 21, and the pulling belt 20 is pulled out from the right side of the tensioning pulley 19. At this time, the pulling belt 20 and the grinding head 21 can be taken out, and the clamping frame 13 is lifted to take out the ground metal tube 12.

[0033] The present invention is applicable to a steel burr grinding device. By setting two winding wheels 24 that can rotate synchronously, the pulling belt 20 can rotate forward and reverse inside the metal tube 12, so that the reciprocating movement of the grinding head 21 can effectively grind the inner wall of the metal tube 12. In addition, since the present application adopts the pulling belt 20 to drive the grinding head 21 to move, the inner wall of the metal tube 12 with a longer length can still be effectively polished.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
