Technical Field
[0001] This utility model relates to the technical field of grinding and polishing devices, and more specifically, to a grinding and polishing device for metal pipe processing. Background Technology
[0002] Grinding and polishing equipment is a highly efficient automated device for surface treatment. It uses mechanical or robotic technology to grind, polish, and deburr the surface of workpieces. Its main functions include improving the surface finish of workpieces and removing machining marks and burrs. It is widely used in the field of metal pipe processing.
[0003] For example, Chinese Patent Publication: A metal pipe polishing device, application number: CN202222742131.X, includes a clamping mechanism and a polishing mechanism, with the clamping mechanism located at the bottom of the polishing mechanism; this utility model is equipped with a clamping mechanism that supports the inner diameter of the metal pipe. The spacing of the support plates is adjusted by rotating the first bidirectional screw to adapt to the length of the metal pipe, and the spacing of the clamping plates is adjusted by rotating the second bidirectional screw to adapt to the size of the inner diameter of the metal pipe. Rubber pads are provided on the opposite side of the clamping plates so that the rubber pads can be compressed when the clamping plates are in contact with the inner diameter of the metal pipe. At the same time, the rubber pads have the function of increasing the coefficient of friction. The polishing roller is moved laterally by moving the moving block to adapt to the length of the metal pipe, thereby polishing the surface of the metal pipe. The height of the fixed frame is adjusted to adapt to the height of the metal pipe for polishing.
[0004] However, after the grinding and polishing process, the metal pipes generally have residual debris on the outer wall. The traditional method requires workers to transfer the pipes to a special cleaning station, which not only increases the extra working time and labor costs, but also makes it easy for the metal debris left on the outer wall of the metal pipe to cause secondary scratches when multiple grinding and polishing processes are required. Utility Model Content
[0005] The main purpose of this utility model is to provide a grinding and polishing device for metal pipe processing, which can effectively solve the problem of residual debris on the outer wall of metal pipes after grinding and polishing in the background art. Traditional processing methods require workers to transfer the pipes to a dedicated cleaning station, which not only increases the extra working time and labor costs, but also makes it easy for the metal debris remaining on the outer wall of the metal pipe to cause secondary scratches when multiple grinding and polishing processes are required.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a grinding and polishing device for metal pipe processing, comprising a grinding and polishing device body, two unidirectional moving platforms on the grinding and polishing device body, a first hydraulic rod fixedly mounted on the unidirectional moving platform, a connecting plate fixedly mounted on the first hydraulic rod, a protective shell fixedly mounted on the connecting plate, a collecting component mounted on one side below the protective shell, a semi-circular groove and a recessed groove on the protective shell, two air grooves mounted on the side of the semi-circular groove near the recessed groove, several cleaning brushes mounted between the two air grooves, several air supply grooves mounted between the air grooves and the recessed groove, and a vacuum pump and a filter plate fixedly installed in the recessed groove.
[0007] Preferably, the semicircular groove is located on the side away from the first hydraulic rod, the cleaning brush is fixedly installed in the semicircular groove, and the two sides of the air delivery groove are respectively connected to the air groove and the recess.
[0008] Preferably, the collection component includes a component base, a temporary storage groove is provided on the component base, a first sliding groove and a second sliding groove are provided on the temporary storage groove, and a base plate is slidably disposed in the first sliding groove.
[0009] Preferably, a second hydraulic rod is fixedly installed inside the second chute, and a top plate is fixedly installed on the second hydraulic rod.
[0010] Preferably, the component base is fixedly connected to the protective shell, and the temporary storage slot is connected to the groove.
[0011] Preferably, the first groove is located directly below the second groove.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] (1) When the metal tube is finished grinding or after one grinding, the rotation of the metal tube is not stopped. Then, the protective shell is moved towards the metal tube by the first hydraulic rod so that the two protective shells fit together. At this time, the metal tube is located in the semi-circular groove. Several cleaning brushes are used to clean the metal debris on the outer wall surface of the metal tube. At the same time, the metal debris cleaned by the cleaning brushes is sucked into the groove by the vacuum pump. The vacuum pump is protected by the filter plate to prevent metal debris from entering the vacuum pump. Then, the protective shell is slowly moved to one side by the one-way moving table, so as to thoroughly clean the metal debris on the outer wall surface of the metal tube. The intermediate cleaning step is eliminated, the processing time is shortened, the labor cost is reduced, and the risk of secondary scratches caused by metal debris during multiple grinding is effectively eliminated.

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0020] like Figures 1 to 3 As shown, a grinding and polishing device for metal pipe processing includes a grinding and polishing device body 1. The grinding and polishing device body 1 is provided with two unidirectional moving stages 2. A first hydraulic rod 3 is fixedly provided on the unidirectional moving stage 2. A connecting plate 13 is fixedly provided on the first hydraulic rod 3. A protective shell 4 is fixedly provided on the connecting plate 13. A collecting component 5 is provided on one side below the protective shell 4. A semi-circular groove 6 and a groove 9 are provided on the protective shell 4. Two air grooves 7 are provided on the side of the semi-circular groove 6 near the groove 9. A plurality of cleaning brushes 8 are provided between the two air grooves 7. A plurality of air supply grooves 10 are provided between the air grooves 7 and the groove 9. A vacuum pump 11 and a filter plate 12 are fixedly installed in the groove 9.
[0021] like Figure 4 As shown, in another embodiment of the present invention, the collecting component 5 includes a component base 501, a temporary storage groove 502 is provided on the component base 501, a first sliding groove 503 and a second sliding groove 504 are provided on the temporary storage groove 502, and a base plate 505 is slidably disposed in the first sliding groove 503.
[0022] A second hydraulic rod 506 is fixedly installed inside the second chute 504, and a top plate 507 is fixedly installed on the second hydraulic rod 506;
[0023] When it is necessary to move the metal debris in the groove 9 into the temporary storage tank 502, the top plate 507 is moved into the second slide 504 by the second hydraulic rod 506, releasing the top plate 507 from blocking the upper inlet of the temporary storage tank 502. Then, the metal debris in the groove 9 falls into the temporary storage tank 502 under the action of gravity for temporary storage. The top plate 507 is then moved back to its original position by the second hydraulic rod 506 to re-block the upper inlet of the temporary storage tank 502, preventing the metal debris in the temporary storage tank 502 from being sucked into the groove 9 when cleaning the metal pipe.
[0024] When there are too many metal scraps in the temporary storage tank 502, the bottom plate 505 is pulled out from the first chute 503, and the metal scraps in the temporary storage tank 502 can leave the temporary storage tank 502 under the action of gravity, which is convenient for recycling and reuse.
[0025] Working principle of a grinding and polishing device for metal tube processing:
[0026] In use, after the metal tube is polished or after one polishing cycle, the rotation of the metal tube is not stopped. Then, the first hydraulic rod 3 moves the protective shell 4 towards the metal tube, so that the two protective shells 4 fit together. Since the two protective shells 4 are located on both sides of the metal tube, the metal tube is located in the semi-circular groove 6. Several cleaning brushes 8 are used to clean the metal debris on the outer wall surface of the metal tube. At the same time, the vacuum pump 11 extracts air from the groove 9, making the groove 9 a negative pressure state. The groove 9 extracts air from the air groove 7 through the air supply groove 10, and then extracts air near the metal tube through the air groove 7, thereby sucking the metal debris cleaned by the cleaning brushes 8 into the groove 9. The filter plate 12 is used to protect the vacuum pump 11 to prevent metal debris from entering the vacuum pump 11. Then, the one-way moving table 2 slowly moves the protective shell 4 to one side, thereby thoroughly cleaning the metal debris on the outer wall surface of the metal tube. This eliminates the intermediate cleaning step, shortens the processing time, reduces labor costs, and effectively eliminates the risk of secondary scratches caused by metal debris during multiple polishing cycles.
[0027] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
