The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0029] like Figures 1 to 6 As shown, the present invention provides a metal parts grinding device, comprising: a machine base 1; a protective cover 2 fixedly installed on the machine base 1; a fixing mechanism for fixing a metal tube; a grinding mechanism for grinding the metal tube; and a cooling mechanism for cooling the metal tube.

[0030] The fixing mechanism includes: a housing 3 fixedly installed on the machine base 1; a chuck 4 rotatably installed on the housing 3; and a third motor (not shown) that drives the chuck 4 to rotate, the third motor being fixedly installed inside the housing 3.

[0031] When grinding a metal tube, the chuck 4 can be used to fix the metal tube, and the third motor can be started to drive the chuck 4 to rotate, thereby driving the metal tube to rotate. This makes it easier to grind the outside of the metal tube in a circumferential manner, thus improving grinding efficiency.

[0032] It should be noted that the chuck 4 is preferably an electric three-jaw chuck 4.

[0033] The polishing mechanism includes: a mounting housing 14; a connecting gear 20 rotatably mounted inside the mounting housing 14; a second motor 15 that drives the connecting gear 20 to rotate, the second motor 15 being fixedly mounted on the mounting housing 14; a rack 21 meshing with the connecting gear 20; two racks 21 are provided, one rack 21 with a coarse polishing plate 16 fixedly mounted at its bottom end; the other rack 21 with a fine polishing plate 17 fixedly mounted at its bottom end; a limit strip 22 is fixedly mounted on the rack 21, and a limit groove is provided inside the mounting housing 14, the limit strip 22 being slidably mounted in the limit groove.

[0034] After the metal tube is fixed, the second motor 15 is started to drive the connecting gear 20 to rotate. The connecting gear 20 drives the two racks 21 to move synchronously. Under the limiting action of the limiting strip 22 and the limiting groove, the two racks 21 move along the path of the limiting groove, ensuring the stability of the limiting strip 22 when it moves.

[0035] When polishing metal tubes, rough polishing is required first, followed by fine polishing. The goal of the rough polishing stage is to quickly remove larger unevenness on the surface of the metal tube, while the goal of the fine polishing stage is to further improve the smoothness and precision of the metal tube surface, remove minor imperfections left in the rough polishing stage, and achieve a more refined surface treatment.

[0036] When grinding metal tubes, rough grinding is performed first, followed by fine grinding. As a result, rack 21 first drives the rough grinding plate 16 to move downward and abut against the outside of the metal tube. At the same time, another rack 21 drives the fine grinding plate 17 to move upward.

[0037] Similarly, when the metal tube is being finely polished, as the coarse polishing plate 16 moves upward, the fine polishing plate 17 moves downward and comes into contact with the outside of the metal tube.

[0038] As can be seen from the above, when grinding the metal tube, the second motor 15 drives the connecting gear 20 to rotate, so that the two racks 21 move in opposite directions. Thus, the positions of the coarse grinding plate 16 and the fine grinding plate 17 can be automatically adjusted according to the coarse grinding stage and the fine grinding stage of the metal tube, thereby realizing the coarse grinding and fine grinding of the metal tube and improving the grinding efficiency.

[0039] The grinding mechanism also includes: a moving assembly that moves the coarse grinding plate 16 and the fine grinding plate 17; the moving assembly includes: a threaded rod 11 rotatably mounted on the protective cover 2; a first motor 10 that drives the threaded rod 11 to rotate, the first motor 10 being fixedly mounted on the protective cover 2; a moving seat 12 threadedly connected to the threaded rod 11; a limiting opening opened on the moving seat 12; a limiting plate 13 slidably mounted in the limiting opening, both sides of the limiting strip 22 being fixedly mounted inside the protective cover 2; and a mounting shell 14 fixedly connected to the moving seat 12.

[0040] When grinding a metal tube, the first motor 10 is started to drive the threaded rod 11 to rotate. Under the limiting action of the limiting plate 13, the moving seat 12 moves along the axial direction of the threaded rod 11. The moving seat 12 drives the mounting shell 14 to move, which in turn drives the coarse grinding plate 16 and the fine grinding plate 17 to move. Together with the fixing mechanism, the metal tube is rotated, thereby enabling coarse and fine grinding of different positions of the metal tube, further improving the grinding efficiency of the metal tube.

[0041] The cooling mechanism includes: a cooling tank 7 fixedly installed on the machine base 1, which stores coolant; a water pump 6 fixedly installed on the cooling tank 7; an inlet pipe 8 connecting the cooling tank 7 and the water pump 6; a nozzle 18 hingedly installed on the mounting housing 14; and a switching assembly for switching the coolant flow direction. The switching assembly includes: a fixed pipe 25 fixedly installed on the mounting housing 14; a movable block 28 slidably installed in the fixed pipe 25; a threaded shaft 26 coaxially connected to the linkage gear 20; a threaded pipe 27 threadedly connected to the threaded shaft 26; a collection chamber 29 opened on the movable block 28; and an outlet pipe 9 connecting the water pump 6 and the collection chamber 29. The threaded pipe 27 is fixedly connected to the movable block 28. There are two nozzles 18, one of which is connected to the fixed pipe 25 through a first liquid guide pipe 23, and the other nozzle 18 is connected to the fixed pipe 25 through a second liquid guide pipe 24. A perforated plate 5 is fixedly installed on the machine base 1, and a collection box is provided inside the machine base 1, with the collection box located below the perforated plate 5.

[0042] When the metal tube is coarsely ground, the second motor 15 is started, causing the coarse grinding plate 16 to move downward and the fine grinding plate 17 to move upward. Since the threaded shaft 26 is coaxially connected with the connecting gear 20, the threaded shaft 26 rotates and drives the threaded tube 27 to move. The threaded tube 27 drives the moving block 28 to slide inside the fixed tube 25. Since the fixed tube 25 is a rectangular tube and the moving block 28 is a rectangular block, the threaded tube 27 can be limited by the cooperation between the fixed tube 25 and the moving block 28, so that the threaded tube 27 can move along the axial direction of the threaded shaft 26, thereby driving the moving block 28 to move closer to the threaded shaft 26. When the coarse grinding plate 16 abuts against the outside of the metal tube, the liquid outlet of the gas collecting chamber is aligned with the liquid inlet pipe 8 of the first liquid guide pipe 23.

[0043] At this time, the water pump 6 is started to draw out the coolant in the cooling tank 7 through the inlet pipe 8 and deliver it to the collection chamber 29 through the outlet pipe 9. It is then delivered to the nozzle 18 near the coarse grinding plate 16 through the first guide pipe 23 and sprayed out through the nozzle 18. Since the outlet end of the nozzle 18 is pointed to the coarse grinding plate 16, the sprayed coolant can cool the grinding area of ​​the coarse grinding plate 16.

[0044] When the metal tube is being finely polished, the second motor 15 is started to rotate in the opposite direction, causing the fine polishing plate 17 to move downward and the coarse polishing plate 16 to move upward. At the same time, the moving block 28 is driven to move away from the threaded shaft 26. When the fine polishing plate 17 comes into contact with the outside of the metal tube, the liquid outlet of the gas collecting chamber is aligned with the liquid inlet pipe 8 of the second liquid guide pipe 24.

[0045] At this time, the water pump 6 is started to draw out the coolant in the cooling tank 7 through the inlet pipe 8 and deliver it to the collection chamber 29 through the outlet pipe 9. It is then delivered to the nozzle 18 near the fine grinding plate 17 through the second guide pipe 24 and sprayed out through the nozzle 18. Since the outlet end of the nozzle 18 is pointed to the fine grinding plate 17, the sprayed coolant can cool the grinding area of ​​the fine grinding plate 17.

[0046] After use, the coolant mixed with grinding debris flows through the through holes on the perforated plate 5 into the collection box for collection, thereby maintaining the cleanliness of the machine tool 1 surface.

[0047] As can be seen from the above, when performing rough grinding and fine grinding on metal pipes, the flow direction of the coolant can be switched so that the coolant flows to the corresponding nozzle 18, thereby meeting the cooling requirements.

[0048] A linkage rod 19 is fixedly installed on the nozzle 18. A guide groove 30 is provided at the bottom of the limiting plate 13. The linkage rod 19 is slidably installed in the guide groove 30. The guide groove 30 is a wave groove with uniform waveform and a certain depth and width. The diameter of the linkage rod 19 is smaller than the width of the guide groove 30, so that the linkage rod 19 can sway while sliding along the inner cavity of the guide groove 30.

[0049] While the mounting housing 14 moves the coarse grinding plate 16 and the fine grinding plate 17, it can also move the nozzle 18. The nozzle 18 moves the connecting rod 19. When the top of the connecting rod 19 slides along the path of the guide groove 30, it can drive the nozzle 18 to swing back and forth, so that the nozzle 18 moves along the axial direction of the threaded rod 11 while swinging, thereby expanding the spraying range of the nozzle 18 and making the coolant fully contact the grinding part of the metal pipe, thus improving the cooling effect on the grinding part of the metal pipe.

[0050] This application can automatically adjust the positions of the coarse grinding plate 16 and the fine grinding plate 17 according to the coarse grinding stage or the fine grinding stage of the metal pipe, and simultaneously switch the coolant flow direction to the corresponding nozzle 18, thereby meeting the cooling requirements.

[0051] Working principle: During use, the metal tube is fixed by the fixing mechanism. At this time, the second motor 15 is started to drive the connecting gear 20 to rotate. The connecting gear 20 drives the two racks 21 to move synchronously. Under the limiting action of the limiting strip 22 and the limiting groove, the two racks 21 move along the path of the limiting groove, ensuring the stability of the limiting strip 22 during movement. Since the metal tube is first roughed and then finely ground, the rack 21 first drives the rough grinding plate 16 to move downward and abut against the outside of the metal tube. At the same time, the other rack 21... The coarse grinding plate 16 moves upward while the fine grinding plate 17 moves downward and abuts against the outside of the metal tube. As can be seen from the above, when the metal tube is being polished, the second motor 15 drives the connecting gear 20 to rotate, so that the two racks 21 move in opposite directions. Thus, the positions of the coarse grinding plate 16 and the fine grinding plate 17 can be automatically adjusted according to the coarse grinding stage and the fine grinding stage of the metal tube, thereby realizing the coarse grinding and fine grinding of the metal tube and improving the grinding efficiency.
