Description

Technical Field

[0001] This utility model belongs to the field of metal pipe grinding technology, specifically relating to a grinding device for metal pipes capable of bilateral grinding. Background Technology

[0002] During the production and processing of metal pipes, burrs, oxide scale, and irregular protrusions often remain on the pipe surface due to rolling, cutting, and other processes. These defects not only affect the smoothness of the pipe's appearance but also lead to corrosion risks during subsequent use, reducing the pipe's structural stability and service life. Furthermore, impurities or unevenness on the pipe surface can negatively impact its connection accuracy and sealing performance, making it difficult to meet the high standards required by industries such as construction, machinery, and chemicals. Therefore, grinding metal pipes has become an indispensable part of the production process. Grinding removes surface defects, improves the surface quality and performance of the pipes, and ensures they meet practical application requirements.

[0003] In existing metal pipe grinding devices, the height and position of the grinding components are typically fixed. When dealing with metal pipes of different diameters and specifications, the grinding components struggle to achieve a good fit with the pipe surface. Either the gap is too large, resulting in poor contact between the grinding components and the metal pipe, causing the pipe to detach from the feed assembly; or the gap is too small, preventing effective contact for grinding. This inability to adapt to different pipe types directly leads to poor contact during grinding, resulting in uneven grinding and missed areas on the pipe surface. This severely affects grinding quality, increases subsequent rework costs, and may even render unusable pipes, hindering overall production efficiency and product qualification rates.

A speed supply component is provided on each worktable. A translation component is provided on the upper side of each worktable. A positioning component is provided on each translation component. A grinding component is provided on the positioning component. Two sets of replacement components are provided between the two worktables. A blocking block is fixed to the outer side of each worktable near the replacement component. A first shelf is provided in front of the replacement component. A second shelf is provided behind the replacement component. A metal pipe is placed on top of the first shelf.

[0007] As a further optimization of this utility model, each set of speed supply components includes a support frame fixed on the upper side of the workbench. A first rotating rod is rotatably passed through the inner side of the support frame. A roller is rotatably sleeved on the surface of the first rotating rod.

The guide rods 705 are used to assist the Z-shaped block in stable lifting and lowering.

[0027] like Figures 1 to 3As shown, each workbench 1 is equipped with a speed supply assembly 3, which drives the metal pipe 11 to rotate between the roller 303 and the wheel 309. Each speed supply assembly 3 includes a support frame 301 fixed to the upper side of the workbench 1. The support frame 301 supports the first rotating rod 302. The first rotating rod 302 rotatably passes through the inner side of the support frame 301. The first rotating rod 302 drives the roller 303 to rotate. The roller 303 is rotatably sleeved on the surface of the first rotating rod 302. The roller 303 is used to contact the metal pipe 11 to assist in rotation. A sprocket 306 is sleeved through the end of the first rotating rod 302 away from the blocking block 8. The sprocket 306 is used to transmit power.

[0028] like Figure 2 , Figure 4 and Figure 5 As shown, each workbench 1 has a translation component 4 on its upper side. The translation component 4 is used to drive the positioning component 5 to translate. Each translation component 4 includes a fixed housing 402 fixed to the upper side of the workbench 1. The fixed housing 402 is used to accommodate components such as a sliding block 403. The sliding block 403 is slidably connected to the inner side of the fixed housing 402. The sliding block 403 is used to drive the positioning component 5 to move. A sliding groove is opened on the outer side of the sliding block 403 to accommodate a second rotating rod 404. A first servo motor 401 is provided on the outer side of the fixed housing 402. The first servo motor 401 is used to provide translational force. The first servo motor 401 in this utility model is all of the ZTRPHEZ model. The -075+EZ71S synchronous servo motor has a second rotating rod 404 fixed to the output shaft end of the first servo motor 401, which passes through the sliding groove. The second rotating rod 404 is used to drive the gear 406 to rotate. A limit ring 405 is fixed to the end of the second rotating rod 404 away from the first servo motor 401. The limit ring 405 is used to limit the position of the second rotating rod 404. Both ends of the second rotating rod 404 are sleeved with gears 406, which are used to mesh with racks 407 to transmit power. Both ends of the sliding block 403 have racks 407 fixed to the bottom inner sides that mesh with gears 406. The racks 407 are used to cooperate with gears 406 to realize the movement of the sliding block 403.

[0029] like Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, each translation component 4 is equipped with a positioning component 5. The positioning component 5 is used to position and adjust the height of the grinding component 6. Each positioning component 5 includes a component housing 501 fixed to the upper side of the sliding block 403. The component housing 501 is used to accommodate the various parts of the positioning component 5. Two sets of slide rails 502 are provided inside the component housing 501. The slide rails 502 are used to guide the sliding of the slider 503. A slider 503 is slidably connected to the outer side of each set of slide rails 502. The slider 503 is used to assist the lifting plate 510 in stable vertical movement. Limit blocks 504 are fixed at both the upper and lower ends of one set of slide rails 502. The limit blocks 504 are used to limit the sliding range of the slider 503. A second servo motor 505 is provided at the bottom inner side of the component housing 501. The second servo motor 505 is used to provide lifting power. In this utility model... The second servo motor 505 is a Xinje MS6H-80CM20B1-20P7 high inertia servo motor. The output shaft of the second servo motor 505 is sleeved with a lower rotating wheel 507, which drives the belt 509 to rotate. A fixing rod 506 is fixed inside the component housing 501. The fixing rod 506 supports the upper rotating wheel 508. The surface of the fixing rod 506 is rotatably sleeved with the upper rotating wheel 508, which assists the belt 509 to rotate. The belt 509 is coupled between the lower rotating wheel 507 and the upper rotating wheel 508. The belt 509 drives the lifting plate 510 to rise and fall. The lifting plate 510 is fixed on the outside of the slider 503 on one side of the belt 509. The lifting plate 510 is used to install the grinding component 6. The other side of the belt 509 passes through the lifting plate 510.

[0030] like Figures 1 to 3 As shown, a grinding component 6 is provided on the positioning component 5. The grinding component 6 is used to grind the metal pipe 11. Each grinding component 6 includes a splash-proof shell 602 fixed on the upper side of the lifting plate 510. The splash-proof shell 602 is used to prevent grinding debris from splashing and to provide support for the grinding component 6. A third servo motor 601 is provided on the outside of the splash-proof shell 602. The third servo motor 601 is used to provide grinding power. The third servo motor 601 in this utility model is a Superco 4060ER-S high-speed spindle motor. A grinding wheel 603 is fixedly sleeved on the output shaft end of the third servo motor 601. The grinding wheel 603 is used to directly grind the metal pipe 11.

[0031] It should be noted that, in the use of this grinding device for double-sided grinding of metal tubing 11, the operator places the metal tubing 11 on the second shelf 10. The metal tubing 11 will roll from the higher end to the lower end due to the height difference between the front and rear ends of the second shelf 10 until it contacts the side of the blocking block 8 and stops. At this point, the metal tubing 11 will be supported by the Z-shaped block 704 and will no longer be in contact with the second shelf 10. Subsequently, the cylinder 702 in the replacement assembly 7 drives the Z-shaped block 7... 04. During the upward movement, the Z-shaped block 704 will drag the metal pipe 11 upward together. When the metal pipe 11 on the Z-shaped block 704 is higher than the blocking block 8, the output end of the cylinder 702 will descend, causing the Z-shaped block 704 to descend along the guide rod 705 to the upper side of the tray 703, so that the metal pipe 11 contacts the upper side of the blocking block 8. Then the Z-shaped block 704 descends to a position lower than the blocking block 8. At this time, the metal pipe 11 will slide along the upper side of the blocking block 8 to the speed supply component 3.

[0032] When the metal pipe 11 is on the speed supply assembly 3, the speed supply motor 304 in the speed supply assembly 3 will start to work. The speed supply motor 304 drives the first rotating rod 302 to drive the roller 303 to rotate by driving the main sprocket 305, chain 307 and slave sprocket 306 to transmit kinetic energy. At this time, the metal pipe 11 is located between the roller 303 and the roller 309 supported by the bracket 308. When the roller 303 rotates, it transmits kinetic energy to the metal pipe 11 and the roller 309, so that the metal pipe 11 rotates at a uniform speed on the speed supply assembly 3.

[0033] Subsequently, driven by the first servo motor 401, the translation component 4 drives the sliding block 403 to translate out of the fixed housing 402 to a suitable position through the meshing relationship between the gear 406 and the rack 407. When the suitable position is reached, the second servo motor 505 in the positioning component 5 starts to work, driving the lower rotating wheel 507, the upper rotating wheel 508 and the belt 509, so that the belt 509 drives the lifting plate 510 to move vertically. The translation component 4 and the positioning component 5 enable the grinding component 6 on the lifting plate 510 to change the contact point with the metal tube 11 so that the metal tube 11 can roll stably on the speed supply component 3. At the same time, it can also adapt to different models of metal tubes 11, avoiding poor contact point of the grinding component 6 or failure to contact the metal tube 11 due to the metal tube 11 being too large or too small, which would result in poor grinding quality of the final metal tube 11.

[0034] After positioning is completed, the third servo motor 601 in the grinding component 6 drives the grinding wheel 603 to grind both ends of the metal tube 11. After the grinding process is completed, the sliding block 403 moves backward into the fixed housing 402 under the drive of the first servo motor 401. Then the replacement component 7 rises again to lift the metal tube 11. The metal tube 11 will slide on the Z-shaped block 704 to the edge of the first shelf 9. When the Z-shaped block 704 is higher than the edge of the first shelf 9, the metal tube 11 will slide to the upper side of the first shelf 9. Then, due to the bottom difference, it will slide to the stop at the front end of the first shelf 9 and stop.

[0035] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
