Description

Technical Field

[0001] This invention relates to the field of impeller grinding technology, specifically to an aluminum alloy impeller grinding device and method. Background Technology

[0002] After aluminum alloy impellers are cast, burrs and flash will appear on the surface of the impeller. They need to be ground and polished to obtain a sufficiently smooth surface before they can be put into use. However, the precision polishing of aluminum alloy impellers requires very high-end equipment. The processing process is difficult to manufacture, has poor versatility, high cost, low processing efficiency, and poor overall processing quality. Patent documents have been issued to improve this.

[0003] For example, Chinese patent CN110253345B discloses a chemical mechanical polishing method and polishing device for an integral impeller. This method involves mixing chemical reagents and abrasives to form a polishing slurry. The entire integral impeller is immersed in the polishing slurry and driven to rotate by a drive motor. Under the combined action of chemical corrosion softening and mechanical scraping removal by the polishing slurry, precision polishing is performed on various parts of the integral impeller surface. The polishing device includes a drive motor, bolts, couplings, mounting plates, support and positioning plates, connecting parts, a base, a container, and plastic foam. This polishing method is suitable for polishing various parts of the outer surface of integral impellers of various sizes and specifications, offering strong versatility, high polishing efficiency, and good overall polishing quality. The polishing device has a simple structure, is easy to manufacture, convenient to operate, stable and reliable, and has low cost.

[0004] Although the aforementioned patent solves the problems of poor versatility, high cost, and low processing efficiency of grinding equipment by mixing chemical reagents with abrasives to form a polishing liquid, the abrasives are not evenly distributed in the polishing liquid. When the impeller rotates and agitates the polishing liquid, the abrasives are mostly dispersed on the outer periphery of the impeller, making it difficult to quickly polish the inner periphery of the impeller. This results in low polishing efficiency for the impeller. Furthermore, large pieces of debris ground off the impeller surface will mix into the polishing liquid. When these large pieces of debris flow across the impeller surface with the polishing liquid, they can easily scratch the impeller surface, thus affecting the processing effect on the impeller. Summary of the Invention

A second telescopic spring is fixedly connected between the top of the inner cavity of the telescopic cylinder and the top of the telescopic rod.

[0014] This invention also discloses a method for grinding aluminum alloy impellers, specifically including the following steps: S1. By opening the buckle and pulling the sealing cover upwards, the rectangular block on the rotating column is disengaged from the rectangular opening. Polishing fluid and abrasive are added to the grinding box. Then, by rotating the limiting sleeve, the limiting sleeve is removed from the surface of the threaded cylinder. The aluminum alloy impeller to be ground is placed on the threaded cylinder, and the limiting sleeve is then placed on the surface of the threaded cylinder. By rotating the limiting sleeve, the limiting sleeve presses and fixes the aluminum alloy impeller to the baffle. The sealing cover is then installed on the grinding box using the buckle, causing the rectangular block on the rotating column to engage in the rectangular opening. Finally, the control switch is activated, causing the drive motor to reciprocate. The lead screw rotates, and the reciprocating lead screw drives the rectangular block to rotate through the rectangular opening, thereby causing the rectangular block to drive the rotating column to rotate. At the same time, the slider inside the slide plate limits the limit rod, causing the reciprocating lead screw to drive the threaded sleeve to move up and down reciprocally. This causes the threaded sleeve to push the threaded cylinder on the baffle to move up and down. The threaded cylinder will drive the aluminum alloy impeller to move up and down reciprocally. At the same time, the reciprocating lead screw will drive the rectangular plate to rotate, and the rectangular plate will drive the threaded cylinder to rotate, thereby driving the aluminum alloy impeller on the threaded cylinder to rotate. The aluminum alloy impeller moves up and down on the surface of the threaded cylinder while rotating. S2. As the threaded sleeve moves upward, it drives the connecting plate upward, which in turn drives the two guide rods upward. The two guide rods push the first filter plate in the sliding groove, causing the first filter plate to tilt and rotate upward. At the same time, the first filter plate squeezes the telescopic rod, causing the telescopic rod to retract into the telescopic cylinder. The two first filter plates eventually tilt into a V-shape below the aluminum alloy impeller, filtering out the abrasive in the polishing liquid in the grinding box and accumulating above the two first filter plates. This allows the aluminum alloy impeller to fully contact and grind the abrasive accumulated on the two first filter plates. When the threaded sleeve moves downward, the two guide rods also move downward, preventing the guide rods from pushing the first filter plates. Through the force of the second telescopic spring, the telescopic rod extends out from the telescopic cylinder and pushes the first filter plate, causing the first filter plate to tilt downward and reset, scattering the abrasive accumulated on the first filter plate. S3. Simultaneously start the first and second water pumps. The first water pump draws the polishing liquid and abrasive from the grinding box into the outlet water pipe through the inlet water pipe, and then into the filter box through the outlet water pipe. The second filter plate in the filter box will filter the polishing liquid and abrasive, and filter out the debris from the aluminum alloy impeller. At the same time, the water supply pipe on the second water pump draws the polishing liquid and abrasive from the two filter boxes into the drain pipe through the three-way pipe, and then discharges them into the grinding box for circulation. S4. As the reciprocating screw rotates, it drives the two second pulleys to rotate. The second pulleys drive the first pulley to rotate via the transmission belt, which in turn drives the rotating rod to rotate. This causes the cam plate on the rotating rod to rotate. Each time the cam plate rotates to the guide plate, it pushes the guide plate upward, thereby causing the second filter plate and the sliding rod to slide upward. Then, through the force of the first telescopic spring, the sliding rod is pulled downward, causing the second filter plate to move downward and reset. Thus, through the continuous rotation of the cam plate, the second filter plate vibrates by moving up and down reciprocating.

[0015] Preferably, a sealed door is hinged to the top of one side of the filter box, and a waterproof pipe is connected to the bottom of the grinding box.

[0016] This invention provides an aluminum alloy impeller grinding device and method. Compared with existing technologies, it has the following advantages: (1) The present invention drives the reciprocating screw to rotate through the drive motor, which in turn drives the threaded cylinder to rotate through the rectangular plate, thereby driving the impeller on the threaded cylinder to rotate. The reciprocating screw drives the threaded sleeve to move up and down, and the impeller on the threaded cylinder moves up and down while rotating, so that the impeller can fully contact the polishing liquid and abrasive. When the threaded sleeve moves upward, it drives the guide rod to move upward, which pushes the first filter plate to tilt and rotate, so that the two first filter plates merge in a V shape below the impeller, and the abrasive in the polishing liquid is gathered on the two V-shaped first filter plates, so that the impeller can be better polished in the dense abrasive, and the impeller can be polished quickly, further improving the polishing efficiency of the impeller.

[0017] (2) The present invention uses a first water pump to draw the polishing liquid and abrasive in the grinding box into a filter box, and filters them through a second filter plate in the filter box. This effectively filters out large pieces of debris mixed in the polishing liquid and abrasive. The filtered polishing liquid and abrasive are then discharged into the grinding box by the second water pump for circulation. This effectively prevents large pieces of debris from scratching the impeller surface and ensures the polishing effect of the impeller.

[0018] (3) The present invention drives the second pulley to rotate while the reciprocating screw rotates, so that the second pulley drives the rotating rod to rotate through the transmission belt and the first pulley. The rotating rod drives the cam plate to rotate, and the cam plate pushes up the guide plate, thereby moving the second filter plate upward. The second filter plate is pulled downward to reset by the force of the first telescopic spring, so that the second filter plate shakes up and down, which can effectively reduce the clogging of the second filter plate and ensure the filtration effect of the second filter plate.

[0019] (4) The present invention uses the force of the second telescopic spring to push the telescopic rod to move downward, thereby pushing the first filter plate to tilt downward, thus ensuring that the first filter plate is reset after tilting upward, and dispersing the abrasive material gathered above the first filter plate back into the grinding box, making the impeller grinding faster.

[0028] This invention also discloses a method for grinding aluminum alloy impellers, specifically including the following steps: S1. By opening the buckle and pulling the sealing cover 4 upward, the rectangular block 65 on the rotating column 64 is disengaged from the rectangular opening 63. Polishing liquid and abrasive are added to the grinding box 2. Then, by rotating the limiting sleeve 610, the limiting sleeve 610 is removed from the surface of the threaded cylinder 67. The aluminum alloy impeller to be ground is placed on the threaded cylinder 67, and the limiting sleeve 610 is placed on the surface of the threaded cylinder 67. By rotating the limiting sleeve 610, the limiting sleeve 610 presses and fixes the aluminum alloy impeller on the baffle 69. The sealing cover 4 is installed on the grinding box 2 by the buckle, so that the rectangular block 65 on the rotating column 64 is inserted into the rectangular opening 63. Then, the control switch is turned on, so that the drive motor 61 drives the reciprocating screw. 62 rotates, and the reciprocating screw 62 drives the rectangular block 65 to rotate through the rectangular opening 63, thereby causing the rectangular block 65 to drive the rotating column 64 to rotate. At the same time, the slider inside the slide plate 613 limits the limit rod 612, causing the reciprocating screw 62 to drive the threaded sleeve 614 to move up and down reciprocally, thereby causing the threaded sleeve 614 to push the threaded cylinder 67 on the baffle 69 to move up and down. The threaded cylinder 67 will drive the aluminum alloy impeller to move up and down reciprocally. At the same time, the reciprocating screw 62 will drive the rectangular plate 66 to rotate, and the rectangular plate 66 will drive the threaded cylinder 67 to rotate, thereby driving the aluminum alloy impeller on the threaded cylinder 67 to rotate, so that the aluminum alloy impeller moves up and down on the surface of the threaded cylinder 67 while rotating. S2. As the threaded sleeve 614 moves upward, it will drive the connecting plate 611 to move upward, thereby driving the two guide rods 73 to move upward. The two guide rods 73 push the first filter plate 71 in the sliding groove 72, causing the first filter plate 71 to tilt and rotate upward. At the same time, the first filter plate 71 will squeeze the telescopic rod 12, causing the telescopic rod 12 to retract into the telescopic cylinder 11. The two first filter plates 71 will eventually tilt into a V-shape below the aluminum alloy impeller, filtering out the abrasive in the polishing liquid in the polishing box 2 and accumulating above the two first filter plates 71, so that the aluminum alloy impeller can fully contact and polish the abrasive accumulated on the two first filter plates 71. When the threaded sleeve 614 moves downward, the two guide rods 73 will also move downward, so that the guide rods 73 will not push the first filter plate 71. Through the force of the second telescopic spring 13, the telescopic rod 12 extends out from the telescopic cylinder 11 to push the first filter plate 71, causing the first filter plate 71 to tilt downward and reset, scattering the abrasive accumulated on the first filter plate 71. S3. Simultaneously start the first water pump 81 and the second water pump 91. The first water pump 81 draws the polishing liquid and abrasive in the grinding box 2 into the outlet water pipe 82 through the inlet water pipe 83, and then into the filter box 5 through the outlet water pipe 82. The second filter plate 106 in the filter box 5 will filter the polishing liquid and abrasive, and filter out the debris from the aluminum alloy impeller. At the same time, the water supply pipe 93 on the second water pump 91 draws the two water supply pipes 95 through the three-way pipe 94, so that the two water supply pipes 95 draw the polishing liquid and abrasive in the two filter boxes 5 into the drain pipe 92, and then discharge them into the grinding box 2 for circulation. S4. As the reciprocating screw 62 rotates, it drives the two second pulleys 103 to rotate. The second pulleys 103 drive the first pulley 102 to rotate via the transmission belt 104, thereby driving the rotating rod 101 to rotate. This causes the cam plate 105 on the rotating rod 101 to rotate. Every time the cam plate 105 rotates to the guide plate 107, it pushes the guide plate 107 upward, thereby driving the second filter plate 106 and the sliding rod 1010 to slide upward. Then, through the force of the first telescopic spring 1011, the sliding rod 1010 is pulled downward, causing the second filter plate 106 to move downward and reset. Thus, through the continuous rotation of the cam plate 105, the second filter plate 106 vibrates by moving up and down reciprocating.

[0029] In S1, the top of one side of the filter box 5 is hinged with a sealed door, and the bottom of the polishing box 2 in S1 is connected to a waterproof pipe.

9. A method for grinding aluminum alloy impellers, characterized in that: Specifically, the following steps are included: S1. By opening the buckle, pull the sealing cover (4) upward to disengage the rectangular block (65) on the rotating column (64) from the rectangular opening (63). Add polishing liquid and abrasive to the grinding box (2). Then, by rotating the limiting sleeve (610), remove the limiting sleeve (610) from the surface of the threaded cylinder (67). Place the aluminum alloy impeller to be ground on the threaded cylinder (67). Then, place the limiting sleeve (610) on the surface of the threaded cylinder (67). By rotating the limiting sleeve (610), the limiting sleeve (610) will press and fix the aluminum alloy impeller on the baffle (69). Install the sealing cover (4) on the grinding box (2) through the buckle, so that the rectangular block (65) on the rotating column (64) is inserted into the rectangular opening (63). Then, start the control switch to drive the drive motor (61) to drive the reciprocating screw. (62) Rotation, the reciprocating screw (62) drives the rectangular block (65) to rotate through the rectangular opening (63), thereby causing the rectangular block (65) to drive the rotating column (64) to rotate. At the same time, the slider inside the slide plate (613) limits the limit rod (612), causing the reciprocating screw (62) to drive the threaded sleeve (614) to move up and down reciprocally, thereby causing the threaded sleeve (614) to push the threaded cylinder (67) on the baffle (69) to move up and down. The threaded cylinder (67) will drive the aluminum alloy impeller to move up and down reciprocally. At the same time, the reciprocating screw (62) will drive the rectangular plate (66) to rotate, and the rectangular plate (66) will drive the threaded cylinder (67) to rotate, thereby driving the aluminum alloy impeller on the threaded cylinder (67) to rotate, so that the aluminum alloy impeller moves up and down on the surface of the threaded cylinder (67) and rotates at the same time. S2. As the threaded sleeve (614) moves upward, it will drive the connecting plate (611) to move upward, thereby driving the two guide rods (73) to move upward. The two guide rods (73) push the first filter plate (71) in the sliding groove (72), causing the first filter plate (71) to tilt and rotate upward. At the same time, the first filter plate (71) will squeeze the telescopic rod (12), causing the telescopic rod (12) to retract into the telescopic cylinder (11). The two first filter plates (71) finally tilt into a V shape below the aluminum alloy impeller, filtering out the abrasive in the polishing liquid in the polishing box (2). The abrasive particles gather above the two first filter plates (71), allowing the aluminum alloy impeller to fully contact and grind the abrasive particles gathered on the two first filter plates (71). When the threaded sleeve (614) moves downward, the two guide rods (73) also move downward, preventing the guide rods (73) from pushing the first filter plates (71). Through the force of the second telescopic spring (13), the telescopic rod (12) extends out from the telescopic cylinder (11) to push the first filter plates (71), causing the first filter plates (71) to tilt downward and reset, scattering the abrasive particles gathered on the first filter plates (71). S3. Simultaneously start the first water pump (81) and the second water pump (91). The first water pump (81) draws the polishing liquid and abrasive in the grinding box (2) into the outlet water pipe (82) through the inlet water pipe (83), and then into the filter box (5) through the outlet water pipe (82). The second filter plate (106) in the filter box (5) will filter the polishing liquid and abrasive, and filter out the debris from the aluminum alloy impeller. At the same time, the water supply pipe (93) on the second water pump (91) draws the two water supply pipes (95) through the three-way pipe (94), so that the two water supply pipes (95) draw the polishing liquid and abrasive in the two filter boxes (5) into the drain pipe (92), and then discharge them into the grinding box (2) for circulation through the drain pipe (92). S4. When the reciprocating screw (62) rotates, it will drive the two second pulleys (103) to rotate. The second pulleys (103) will drive the first pulley (102) to rotate through the transmission belt (104), thereby driving the rotating rod (101) to rotate, causing the cam plate (105) on the rotating rod (101) to rotate. Every time the cam plate (105) rotates to the guide plate (107), it will push the guide plate (107) upward, thereby driving the second filter plate (106) and the sliding rod (1010) to slide upward. Then, through the force of the first telescopic spring (1011), the sliding rod (1010) is pulled downward, driving the second filter plate (106) to move downward and reset. Thus, through the continuous rotation of the cam plate (105), the second filter plate (106) moves up and down reciprocally to vibrate.

10. A method for grinding aluminum alloy impellers according to claim 9, characterized in that: The top of one side of the filter box (5) is hinged with a sealed door, and the bottom of the polishing box (2) is connected to a waterproof pipe.
