[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0019] like Figures 1-9 The device for polishing the surface of an air outlet workpiece shown in the figure comprises a processing table 1, a rotating column 2 is rotatably installed on the upper surface of the processing table 1 through a driving mechanism, and the two side surfaces of the rotating column 2 are respectively connected to a movable plate 3 through a distance adjustment mechanism, and a limit block 9 is fixedly connected to the end of the upper surface of the movable plate 3, and a support rod mechanism is provided at the end of the movable plate 3 away from the rotating column 2, and a lifting plate 24 is connected to a lifting mechanism at a corner of the upper surface of the processing table 1, and a vertical plate 27 is fixedly connected to the upper surface of the lifting plate 24, and a transverse grinding roller 30 is rotatably installed on the side of the vertical plate 27 close to the rotating column 2, and a transmission mechanism is provided between the end of the transverse grinding roller 30 away from the rotating column 2 and the lower end of the rotating column 2, a slide 37 is installed on one side of the upper surface of the processing table 1 through an XY moving mechanism, and a liquid spraying grinding mechanism is provided on the lower surface of the slide 37; like Figure 8 、 Figure 9 As shown, the air vent housing 41 is placed on the upper surface of the processing table 1 , the two limit blocks 9 are tightly supported on the inner edge of the vent 43 , and the support rod mechanism is against the inner wall of the air vent housing 41 .

[0020] like Figure 2 As shown, the driving mechanism includes a fixing frame 14 fixedly mounted on the lower surface of the processing table 1, a driving motor 15 is fixedly mounted on the lower surface of the fixing frame 14, a driving shaft 13 is fixedly mounted on the output shaft of the driving motor 15, and the upper end of the driving shaft 13 is fixedly mounted on the lower surface of the rotating column 2.

[0021] like Figure 2 、 Figure 4 、 Figure 5 As shown, the transmission mechanism includes a key shaft 21 that rotates and passes through the upper surface of the lifting plate 24, and the upper end of the key shaft 21 is fixedly installed with a third bevel gear 22, and the end of the transverse grinding roller 30 away from the rotating column 2 is fixedly connected to the grinding shaft 28, and the grinding shaft 28 rotates and passes through the outer surface of the vertical plate 27, and one end of the grinding shaft 28 is fixedly installed with a fourth bevel gear 29, and the fourth bevel gear 29 is meshed with the third bevel gear 22, and the lower end of the key shaft 21 is slidingly sleeved with a vertical shaft 19, and the upper end surface of the vertical shaft 19 is provided with a key groove 23, and the key shaft 21 slides into the inner side of the key groove 23, and the vertical shaft 19 rotates and passes through the upper surface of the processing table 1, and the lower end of the vertical shaft 19 is fixedly provided with a second bevel gear 20, and the inner side of the fixed frame 14 rotates and passes through the horizontal shaft 17, and the two ends of the horizontal shaft 17 are respectively fixedly connected to the first bevel gear 18, and the outer surface of the drive shaft 13 is fixedly sleeved with a drive bevel gear 16, and the two first bevel gears 18 are respectively meshed with the drive bevel gear 16 and the second bevel gear 20. The transmission mechanism is configured so that when the drive motor 15 rotates, the transverse grinding roller 30 can be rotated synchronously. The gear ratio of the first bevel gear 18 to the drive bevel gear 16 is 1:4, ensuring that when the drive bevel gear 16 rotates slightly, the transverse shaft 17 can rotate at a sufficient speed, thereby transmitting sufficient speed to the transverse grinding roller 30 to ensure a polishing effect.

[0022] The lifting mechanism includes a hydraulic cylinder 25 fixedly mounted on the upper surface of the processing table 1, and a plurality of guide rods 26 are fixedly connected to the lower surface of the lifting plate 24. The guide rods 26 slide through the upper surface of the processing table 1. The guide rods 26 are used to improve the stability of the lifting plate 24 when it moves up and down.

[0023] like Figure 1 、 Figure 6 As shown, a concave frame 31 is fixedly mounted on one side of the upper surface of the processing table 1. A Y-axis screw rod 32 is rotatably mounted on the inner side of the concave frame 31. A transverse frame 34 is slidably connected to the upper surface of the concave frame 31. The Y-axis screw rod 32 is threaded through the inner side of the transverse frame 34. A Y-axis motor 33 is fixedly mounted on the rear end of the concave frame 31. The output shaft of the Y-axis motor 33 is fixedly connected to the rear end of the Y-axis screw rod 32. The slide 37 is connected to the transverse frame 34 via a servo mechanism. By controlling the operation of the Y-axis motor 33, the Y-axis screw rod 32 rotates, which in turn controls the forward or backward movement of the transverse frame 34, thereby causing the vertical grinding roller 39 to move forward or backward, polishing the side surface of the air outlet housing 41 and the upper surface of the folded edge 42.

[0024] The servo mechanism includes an X-axis screw 35 rotatably mounted on the inside of a transverse frame 34. The X-axis screw 35 threads through the inside of a slide 37. An X-axis motor 36 is fixedly mounted on one end of the transverse frame 34, and the output shaft of the X-axis motor 36 is fixed to one end of the X-axis screw 35. By controlling the operation of the X-axis motor 36, the X-axis screw 35 rotates, which in turn moves the slide 37 laterally, adjusting the position of the vertical grinding roller 39 to ensure that it is close to the side of the tuyere housing 41 during polishing.

[0025] The liquid spraying and polishing mechanism includes a vertical grinding roller 39 rotatably mounted on the lower surface of a slide 37. A grinding motor 38 is fixedly mounted on the upper surface of the slide 37, with its output shaft fixed to the upper end of the vertical grinding roller 39. A bifurcated nozzle 40 is fixedly mounted at the front edge of the upper surface of the slide 37. During operation, the upper end of the bifurcated nozzle 40 connects to the liquid supply line. The bifurcated nozzle 40 has two nozzles at its lower end, spraying liquid onto one side and the upper surface of the tuyere housing 41, respectively.

[0026] like Figure 3 As shown, the pitch adjustment mechanism includes two chutes 4 provided on the upper surface of the rotating column 2. A snap-in block 5 is fixedly connected to the adjacent ends of the two movable plates 3. The snap-in blocks 5 slide and snap into the inner sides of the chutes 4. A first threaded rod 6 is rotatably passed through the inner sides of the chutes 4. The first threaded rod 6 is threadedly passed through the inner sides of the two snap-in blocks 5. One end of the first threaded rod 6 is fixedly connected to a first polygonal head 7. Turning the first polygonal head 7 with a wrench rotates the first threaded rod 6. The threads provided on the surface of the first threaded rod 6 are symmetrical on both sides, ensuring that the two snap-in blocks 5 move closer to or away from each other during rotation.

[0027] The support rod mechanism includes a second threaded rod 10 threaded through one end of the movable plate 3. A support plate 11 is fixedly connected to the end of the second threaded rod 10 away from the rotating column 2, and a second polygonal head 12 is fixedly connected to the other end of the second threaded rod 10. After the support plate 11 moves laterally, it contacts the inner wall of the tuyere housing 41, creating a large contact surface to prevent damage to the tuyere housing 41.

[0028] During use, the tuyere housing 41 is placed on the upper surface of the processing table 1, and the first polygonal head 7 is rotated to rotate the first threaded rod 6, thereby causing the two movable plates 3 to move away from each other until the two limit blocks 9 are tightened against the inner edge of the vent 43. Then, the second polygonal head 12 is rotated to rotate and move the second threaded rod 10 laterally until the tightening plate 11 abuts against the inner wall of the tuyere housing 41, thereby completing the positioning of the tuyere housing 41. After positioning, Figure 7 、 Figure 8 、 Figure 9As shown, the upper end of the bifurcated nozzle 40 is connected to the chemical polishing liquid supply pipeline, and then the Y-axis motor 33 is controlled to operate, so that the Y-axis screw 32 rotates, driving the horizontal frame 34 to move forward, thereby causing the vertical grinding roller 39 to grind the surface of one side of the tuyere shell 41 and the upper surface of the folded edge 42. At the same time, during the movement, the polishing liquid in the bifurcated nozzle 40 is sprayed onto the upper surface and one side of the tuyere shell 41, as well as the upper surface of the folded edge 42, to ensure that the vertical grinding roller 39 improves the grinding effect when grinding. After grinding one side, the driving motor 15 is rotated to rotate the rotating column 2 ninety degrees, so that the other side of the tuyere shell 41 reaches the vertical grinding roller 39 to facilitate grinding. In this way, the folded edge 42 and the side of the tuyere shell 41 can be polished in sequence during grinding, and the grinding is more comprehensive.

[0029] When the drive motor 15 rotates, the driving bevel gear 16 and the first bevel gear 18 on that side are driven to rotate the horizontal shaft 17. The first bevel gear 18 and the second bevel gear 20 on the other side are driven to rotate the vertical shaft 19. The vertical shaft 19 drives the key shaft 21 to rotate. Under the transmission of the third bevel gear 22 and the fourth bevel gear 29, the grinding shaft 28 and the transverse grinding roller 30 are rotated. The rotating transverse grinding roller 30 cooperates with the rotating tuyere shell 41 to grind the surface of the tuyere shell 41. Since the bifurcated nozzle 40 also sprays polishing liquid on one side of the upper surface of the tuyere shell 41, the tuyere shell 41 is also effectively chemically polished by the transverse grinding roller 30 when it is polished. When the tuyere shell 41 stops rotating, the transverse grinding roller 30 also stops rotating to ensure that no local position is over-polished. Therefore, as the tuyere shell 41 rotates and adjusts its position, the upper surface will be polished synchronously, making the polishing effect more comprehensive.

[0030] By controlling the extension and retraction of the hydraulic cylinder 25, the lifting plate 24 can be moved up and down to change the height of the transverse grinding roller 30. During adjustment, the key shaft 21 will slide up and down relatively along the inner side of the key slot 23 without interference. After being raised as high as possible, it is convenient to arrange the air outlet shell 41 on the surface of the processing table 1. After moving down, it is ensured that the transverse grinding roller 30 can be close to the surface of the air outlet shell 41 to ensure the polishing effect.
