[0047] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0048] like Figures 1 to 8 As shown, the present invention provides a steel pipe grinding device, including: a clamping drive mechanism 1, an outer wall grinding mechanism 2, and an inner wall grinding mechanism 3.

[0049] like Figure 1 , Figure 5 As shown, the clamping drive mechanism 1 includes a support roller group 11, a clamping roller 12, a clamping drive member 13, and a rotation drive member 14. The support roller group 11 and the clamping roller 12 form a fixed station for fixing the steel pipe. The clamping drive member 13 is connected to the clamping roller 12 and is used to drive the clamping roller 12 to move relative to the support roller group 11 to reduce the fixed station and clamp the steel pipe. The rotation drive member 14 is connected to the support roller group 11 and is used to drive the steel pipe to rotate through the support roller group 11.

[0050] The outer wall grinding mechanism 2 includes a guide member 21 and an outer wall grinding member 22. One end of the outer wall grinding member 22 is connected to the guide member 21, and the other end forms a first grinding end for abutting against the outer circumferential surface of the steel pipe. One end of the guide member 21 is connected to the rotary drive member 14 for driving the outer wall grinding member 22 to slide along the steel pipe under the drive of the rotary drive member 14.

[0051] like Figure 3 , Figure 8 As shown, the inner wall grinding mechanism 3 includes an inner wall grinding component 32 and a position driving component 31. The position driving component 31 has a guide end 311 for being disposed inside the steel pipe and a driving end 312 connected to the guide end 311. One end of the inner wall grinding component 32 is connected to the guide end 311, and the other end forms a second grinding end for abutting against the inner circumferential surface of the steel pipe. The driving end 312 is used to drive the inner wall grinding component 32 to slide along the steel pipe through the guide end 311.

[0052] In this device, the steel pipe is placed in a fixed position between the support roller group 11 and the clamping roller 12 during processing. The clamping drive member 13 drives the clamping roller 12 to move relative to the support roller group 11, thereby reducing the fixed position and clamping the steel pipe to prevent axial displacement during processing. After the steel pipe is clamped and fixed, the rotation drive member 14 can drive the steel pipe to rotate via the support roller group 11. The outer wall grinding member 22 and the inner wall grinding member 32 can respectively abut against the inner and outer walls of the steel pipe, fixing the steel pipe and driving its rotation. The outer wall grinding component 22 and the inner wall grinding component 32 can grind the inner and outer walls of the steel pipe respectively. Under the driving action of the rotary drive component 14, the guide component 21 can drive the outer wall grinding component 22 to move along the length of the steel pipe, so as to gradually achieve the grinding of the entire outer surface of the steel pipe. The driving end 312 of the position drive component 31 can drive the inner wall grinding component 32 to move along the steel pipe through the guide end 311. In this process, the grinding of the entire inner surface of the steel pipe is achieved, so that the device can achieve automatic grinding of the inner and outer surfaces of the steel pipe.

[0053] like Figure 1 , Figure 2 As shown, in some embodiments, two support rollers 11, two clamping rollers 12, and two clamping drive members 13 are provided and arranged in a corresponding manner. They are used to fix the two ends of the steel pipe respectively. The support roller group 11 is preferably two support rollers arranged in parallel, and the clamping roller 12 is located above the two support rollers. Of course, depending on the actual use, more than two support rollers can be provided.

[0054] like Figure 3 , Figure 4As shown, in some embodiments, the steel pipe grinding equipment further includes two end grinding mechanisms 4, which are respectively located at both ends of a fixed station. Each end grinding mechanism 4 includes an outer grinding component 41 and an inner grinding component 42. The outer grinding component 41 is located on one side of the steel pipe to grind the outer circumferential surface of the end of the steel pipe, and the inner grinding component 42 is extended into the end of the steel pipe to grind the inner circumferential surface of the end of the steel pipe.

[0055] Furthermore, one end grinding mechanism 4 is fixed by a fixed bracket 6, and the other end grinding mechanism 4 is installed by a trolley pushing mechanism 5 and can move relative to the other end grinding mechanism 4, so that the distance between the two end grinding mechanisms 4 is adjustable to accommodate steel pipes of different lengths.

[0056] Furthermore, the fixed bracket 6 is fixedly installed on the floor of the workshop. The trolley propulsion mechanism 5 includes a slide rail 51, rollers 52 and a slide plate 53. The slide rail 51 is laid flat on the ground. The slide plate 53 is fixedly connected to the corresponding external grinding component 41 and internal grinding component 42. The slide plate 53 is located above the slide rail 51 and rollers 52 are provided at the four corners of its bottom. Each roller 52 is slidably connected to the slide rail 51 so that the slide plate 53 can slide on the slide rail 51 to adjust the distance between the two end grinding mechanisms 4.

[0057] Furthermore, in some embodiments, the external grinding component 41 includes an external grinding roller 411, a support plate 412, a hinge seat 413, and a second cylinder 414. The hinge seat 413 and the second cylinder 414 are both mounted on the slide plate 53 or the fixed bracket 6. The top of the hinge seat 413 is connected to the support plate 412, and the top of the second cylinder 414 abuts against the support plate 412. The external grinding roller 411 is disposed on the support plate 412. In use, the external grinding roller 411 is positioned below the end of the steel pipe. The grinding operation is achieved by utilizing the rotation of the steel pipe. The second cylinder 414 can drive one end of the support plate 412 to rotate upward or downward, thereby driving the external grinding roller 411 to move upward or downward to adjust the grinding position on the end of the steel pipe.

[0058] Furthermore, in some embodiments, the internal grinding component 42 includes a first mounting base 421, a second mounting base 422, a third cylinder 423, and an internal grinding roller 424. The first mounting base 421 is mounted on the slide plate 53 or the fixed bracket 6, and the second mounting base 422 is located above the first mounting base 421. The first mounting base 421 and the second mounting base 422 are connected by the third cylinder 423 and the telescopic rod. The internal grinding roller 424 is connected to the second mounting base 422. The two ends of the position driving member 31 are respectively connected to the grinding rollers of the two internal grinding components 42. In use, one side of the internal grinding roller 424 can abut against the inner wall of the end of the steel pipe to achieve grinding of the end of the steel pipe. The third cylinder 423 can drive the second mounting base 422 to move up and down to adjust the contact between the upper surface of the internal grinding roller 424 and the steel pipe.

[0059] Furthermore, the bottom end of the inner grinding roller 424 protrudes more than the position drive member 31. The inner grinding roller 424 is driven to move downward by the third cylinder 423, so that the side of the inner grinding roller 424 close to the steel pipe abuts against the end of the steel pipe, thereby achieving grinding of the end of the steel pipe.

[0060] This device is suitable for most standard steel pipes of appropriate length. Of course, when the length of the steel pipe varies greatly, the two end grinding mechanisms 4 can work separately to grind both ends of the steel pipe.

[0061] like Figure 5 , Figure 6 As shown, in some embodiments, both clamping drive members 13 include a mounting bracket 131 and a first cylinder 132. The first cylinder 132 is mounted on the mounting bracket 131, which is bolted to the floor of the work area. The first cylinder 132 is located above the clamping roller 12. The drive end 312 of the first cylinder 132 is rotatably connected to the clamping roller 12 via a rotating shaft. In use, the first cylinder 132 can drive the clamping roller 12 to move downwards, so that the clamping roller 12 exerts downward pressure on the steel pipe, thereby firmly fixing the steel pipe between the two support rollers and the clamping roller 12.

[0062] The rotary drive 14 is preferably a first motor. The drive shaft of the first motor is coaxially connected to the central shaft of one of the support rollers in the support roller group 11 to drive the support roller to rotate and drive the steel pipe to rotate. The rotary drive 14 may also include connecting parts for connecting the first motor and the support roller. The first motor may also be replaced by an electric rotating shaft or other electrical device for driving rotation.

[0063] Furthermore, the first motor is a reversible motor. When the first sleeve 212 moves to the top of the first threaded rod 211, it needs to reverse to drive the first sleeve 212 to move to the other end of the first threaded rod 211.

[0064] The clamping drive mechanism also includes two mounting bases 15, which are set on the ground of the corresponding work area. Each mounting base 15 is arranged in correspondence with the clamping drive component 13. The first motor and the support roller group 11 are both mounted on the mounting base 15.

[0065] like Figure 6As shown, in some embodiments, the guide member 21 includes a first threaded rod 211, a first sleeve 212, and an adjusting member 213. The first threaded rod 211 is connected to the drive shaft of the first motor. The first sleeve 212 is sleeved on the first threaded rod 211 and threadedly connected to the first threaded rod 211. The first sleeve 212 is connected to the outer wall grinding member 22 through the adjusting member 213. The guide member 21 also includes a first guide rod 214 and a first sliding sleeve 215. The first guide rod 214 is arranged side by side with the first threaded rod 211. The first sliding sleeve 215 is slidably sleeved on the first guide rod 214 and fixedly connected to the first sleeve 212. During operation, the first motor... While driving the support roller to rotate, it also drives the first threaded rod 211 to rotate, causing the first sleeve 212 on the first threaded rod 211 to move along the length of the first threaded rod 211 under the limitation of the first sliding sleeve 215 and the first guide rod 214. Furthermore, the two ends of the first threaded rod 211 are connected to the corresponding support rollers. The steel pipe is fixed on the support rollers during grinding so that the first threaded rod 211 is arranged side by side with the steel pipe during use. Therefore, the first sleeve 212 drives the outer wall grinding part 22 to move along the steel pipe to facilitate the comprehensive grinding of the steel pipe. The adjusting part 213 is used to adjust the height of the outer wall grinding part 22 so that the outer wall grinding part 22 corresponds to the outer wall of the steel pipe.

[0066] The outer wall grinding component 22 includes a first mounting plate 221 and a first abrasive plate 222. Both the first mounting plate 221 and the first abrasive plate 222 are designed with an arc shape. The first abrasive plate 222 is fixed on the inner side wall of the first mounting plate 221 to increase the contact area between the first abrasive plate 222 and the outer wall of the steel pipe and improve the grinding efficiency.

[0067] like Figure 7 As shown, in some embodiments, the adjusting member 213 includes a mounting box 2131, an adjusting screw 2132, an adjusting sleeve 2133, and an adjusting rod 2135. The mounting box 2131 is fixedly mounted on the first sleeve 212, and the top of the mounting box 2131 is fixedly connected to the first mounting plate 221. The adjusting screw 2132 is rotatably connected to the mounting box 2131. The adjusting sleeve 2133 is sleeved on the adjusting screw 2132 and threadedly connected to the adjusting screw 2132. One end of the adjusting sleeve 2133 is connected to the first mounting plate 221. The adjusting rod 2135 is located on the outside of the mounting box 2131 and is rotatably connected to the mounting box 2131. The adjusting rod 2135 is connected to the adjusting screw 2132 through the bevel gear set 2134. The bevel gear set 2134 includes two bevel gears that mesh and rotatably connect with each other and are respectively connected to the adjusting screw 2132 and the adjusting rod 2135. The adjusting screw 2132 is provided with sliding rods 2136 arranged in parallel on both sides. The sliding rods 2136 slide with the mounting box 2131 and are fixedly connected to the outer wall grinding part 22.

[0068] In use, rotating the adjusting rod 2135 will drive one of the bevel gears in the bevel gear set 2134 to rotate, which in turn drives the bevel gear connected to the adjusting screw 2132 to rotate, thus driving the adjusting screw 2132 to rotate. Since the sliding rod 2136 is slidably connected to the mounting box 2131, the outer wall grinding part 22 can only slide up and down above the mounting box 2131. Under the rotation of the adjusting screw 2132, it can drive the outer wall grinding part 22 to rise and fall through the adjusting sleeve 2133 to adjust the position of the outer wall grinding part 22, so that the first grinding plate 222 corresponds to and fits against the outer wall of the steel pipe, which is beneficial to improving the grinding effect.

[0069] like Figure 8 As shown, in some embodiments, the guide end 311 includes a second threaded rod 3111, a second sleeve 3112, a second guide rod 3113, and a second sliding sleeve 3114. The second threaded rod 3111 is disposed inside the steel pipe and arranged parallel to the steel pipe during use. The second sleeve 3112 is sleeved on the second threaded rod 3111 and threadedly connected to the second threaded rod 3111. The second guide rod 3113 is arranged parallel to the second threaded rod 3111. The second sliding sleeve 3114 is slidably sleeved on the second guide rod 3113. The second sleeve 3112 and the second sliding sleeve 3114 are fixedly connected.

[0070] The drive end 312 is preferably a second motor, but can also be an electric rotating shaft, etc. The drive shaft of the second motor is connected to the second threaded rod 3111.

[0071] In use, the second motor can drive the second threaded rod 3111 to rotate. Under the sliding connection limit between the first sliding sleeve 215 and the second guide rod 3113, it can drive the second sliding sleeve 3114 to translate along the second threaded rod 3111, thereby causing the inner wall grinding part 32 to move along the length of the steel pipe for grinding.

[0072] The inner wall grinding component 32 includes a second mounting plate 321 and a second abrasive plate 322. The second mounting plate 321 is fixedly connected to the second sleeve 3112. Both the second mounting plate 321 and the second abrasive plate 322 have an arc-shaped structure design. The second abrasive plate 322 is fixedly disposed on the outer surface of the second mounting plate 321. The arc-shaped structure design of the second mounting plate 321 and the second abrasive plate 322 can increase the contact area between the second abrasive plate 322 and the inner wall of the steel pipe, further improving the grinding and rust removal effect on the inner wall of the steel pipe.

[0073] Furthermore, the upper grinding surface of the inner wall grinding component 32 is flush with the upper grinding surface of the inner grinding roller 424. Since the two ends of the position drive component 31 are respectively connected to the grinding rollers of the two inner grinding components 42, and the inner wall grinding component 32 is located on the position drive component 31, the third cylinder 423 can adjust the height of the inner wall grinding component 32 accordingly when adjusting the height of the inner grinding roller 424. Since the inner grinding roller 424 is placed at the end of the steel pipe during operation, the position of the inner wall grinding component 32 can be conveniently and quickly adjusted regardless of where the inner wall grinding component 32 is located on the steel pipe.

[0074] Furthermore, the second motor is mounted on the second mounting base 422. The drive shaft of the second motor is rotatably connected to the second mounting base 422 and passes through the second mounting base 422, connecting to the second threaded rod 3111 via the left connecting plate. The other end of the second threaded rod 3111 is provided with a right connecting plate. The second guide rod 3113 is fixedly connected to the left connecting plate and the right connecting plate respectively. The left connecting plate is rotatably connected to the corresponding inner grinding roller 424. The right connecting plate is inserted into the groove provided on the corresponding inner grinding roller 424 and can rotate relative to the groove.

[0075] Working principle: In use, the steel pipe is placed between the two support roller groups 11, so that the steel pipe is positioned between the support rollers. Then, the first cylinder 132 drives the pressing roller 12 downward to press and fix the steel pipe. Then, the second cylinder 414 and the third cylinder 423 are used to adjust the positions of the outer grinding roller 411 and the inner grinding roller 424, so that the outer grinding roller 411 abuts against the outer surface of the end of the steel pipe and the top of the inner grinding roller 424 abuts against the inner surface of the end of the steel pipe. At this time, the second abrasive plate 322 is placed inside the steel pipe and abuts against the inner wall of the steel pipe. Then, the adjusting rod 2135 is rotated to adjust the first abrasive plate 222 to abut against the outer wall of the steel pipe. Then, the rotation drive 14 is driven to drive the support roller to rotate and drive the steel pipe to rotate for grinding. During the grinding process, the rotation drive 14 and the position drive 31 drive the first abrasive plate 222 and the second abrasive plate 322 to move along the length of the steel pipe, so that they can evenly grind the inner and outer walls of the steel pipe.

[0076] The present invention can clamp and fix the steel pipe by means of the clamping drive mechanism 1, and at the same time, the rotating drive component 14 can drive the steel pipe to rotate so as to facilitate the subsequent grinding of the steel pipe.

[0077] The present invention features an outer wall grinding mechanism 2, in which an outer wall grinding component 22 abuts against the outer wall of a steel pipe. When the steel pipe rotates, the component 22 rubs against the outer circumferential surface of the steel pipe to achieve grinding. The guide component 21 drives the outer wall grinding component 22 to move along the length of the steel pipe under the force of the rotation drive component 14. The rotation of the outer wall grinding component 22 and the steel pipe is driven by the same drive device, which can save costs and at the same time make the outer circumferential surface of the steel pipe uniformly ground.

[0078] The present invention has an inner wall grinding mechanism 3, in which the inner wall grinding component 32 can abut against the inner wall of the steel pipe. Under the rotation of the steel pipe, the inner wall of the steel pipe is ground. The position driving component 31 can drive the inner wall grinding component 32 to move along the length of the steel pipe, thereby achieving uniform grinding of the inner circumferential surface of the steel pipe.

[0079] The present invention can grind the inner and outer circumferential surfaces of the end of the steel pipe by means of the end grinding mechanism 4. The positions of the inner grinding roller 424 and the outer grinding roller 411 are adjustable. Adjusting the inner grinding roller 424 can adjust the inner wall grinding part 32. The adjustment part 213 can adjust the outer wall grinding part 22. It has high practicality.

[0080] This invention enables uniform grinding of the inner and outer walls and ends of steel pipes on the same equipment, thereby improving processing efficiency, reducing machine energy consumption, and lowering production costs.

[0081] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
