Detailed Implementation
[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0024] Please see Figure 1-5 This invention provides four technical solutions:
[0025] Example 1
[0026] Please see Figure 1 In this embodiment of the invention, a dent repair device for automobile repair includes a base 1, a lifting rod 2 rotatably mounted on the upper part of the base 1, a repair mechanism 5 mounted on the upper end of the lifting rod 2, a cavity 3 mounted on one side of the base 1, a rotary cylinder 4 for driving the lifting rod 2 to rotate installed inside the cavity 3, and a painting mechanism 6 mounted on one side of the lifting rod 2.
[0027] Please see Figure 1-3 In this embodiment of the invention, the repair mechanism 5 includes limiting plates 51 disposed at the two edges of the upper end of the lifting rod 2. A hollow rod 52 is rotatably disposed between the two limiting plates 51. A first moving shaft 53 is laterally slidably disposed inside the hollow rod 52. One end of the first moving shaft 53 extends out of the hollow rod 52 away from the limiting plate 51 and is connected to a cylinder 54. A suction cup 55 is disposed at the end of the cylinder 54 away from the first moving shaft 53, and a heating mechanism 56 is disposed on one side of the cylinder 54. A repair auxiliary mechanism 57 is disposed between the upper sides of the two limiting plates 51. A heating mechanism 56 is disposed at the end of the hollow rod 52 near the limiting plate 51. A grinding mechanism 58 is provided, and a displacement servo motor 59 is installed in the middle of one side of the hollow rod 52. The output shaft of the displacement servo motor 59 is located inside the hollow rod 52 and connected to a drive gear 510. One end of the first moving shaft 53 is located inside the hollow rod 52 and connected to a second rack 511. The second rack 511 is located below the drive gear 510 and meshes with it. A vacuum pump 512 is installed on the upper part of the end of the hollow rod 52 away from the limiting plate 51. The output end of the vacuum pump 512 is connected to a gas supply pipe 513. The gas supply pipe 513 is connected to the end of the cylinder 54 near the first moving shaft 53 and communicates with its interior.
[0028] In the above scheme: First, adjust the position of the suction cup 55. Then, the displacement servo motor 59 drives the drive gear 510 to rotate. The drive gear 510 drives the second rack 511, which meshes with it, to move. The second rack 511 drives the first moving shaft 53 to move, so that the suction cup 55 is attached to the sheet metal and the recessed part is located inside the suction cup 55. Then, the vacuum pump 512 is activated to evacuate the inside of the cylinder 54, so that the suction cup 55 can be firmly attached to the sheet metal. Then, the displacement servo motor 59 continues to work, so that the first moving shaft 53 moves away from the sheet metal. In this way, the suction cup 55 will stretch the recessed part and flatten it. After flattening, the vacuum pump 512 releases the air, so that the suction cup 55 is no longer attached to the sheet metal.
[0029] For further details, please refer to Figure 2 and Figure 4 In this embodiment of the invention, the heating mechanism 56 includes a hot air blower 565 disposed on one side of the lifting rod 2 and an air inlet 561 disposed on one side of the cylinder 54. The air outlet end of the hot air blower 565 and one end of the air inlet 561 are connected by an air supply pipe 566. A valve 562 is disposed on the air inlet 561, and the end of the air inlet 561 away from the air supply pipe 566 is located inside the cylinder 54 and connected to a hollow annular body 563. A plurality of nozzles 564 communicating with the interior of the hollow annular body 563 are disposed on the inner side of the hollow annular body 563. The nozzles 564 point to the position of the suction cup 55. When the hot air blower 565 works and the valve 562 is opened, hot air enters the hollow annular body 563 through the air supply pipe 566 and then sprays out from the nozzles 564, spraying towards the recessed part to soften it, making it easier to flatten the recessed part.
[0030] Example 2 differs from Example 1 in that:
[0031] Please see Figure 5 In this embodiment of the invention, the lifting rod 2 includes a vertical cylinder 21. A threaded sleeve 22 is longitudinally slidably installed inside the vertical cylinder 21. The upper end of the threaded sleeve 22 extends out of the vertical cylinder 21. A screw 23 is rotatably arranged on the lower side inside the vertical cylinder 21. The threaded sleeve 22 is screwed to the outside of the screw 23 by threads. A driven bevel gear 24 is arranged on the lower end of the screw 23. A lifting servo motor 25 is installed on one side of the vertical cylinder 21. The output shaft of the lifting servo motor 25 is located inside the vertical cylinder 21 and connected to a main bevel gear 26 corresponding to the driven bevel gear 24. The main bevel gear 26 meshes with the driven bevel gear 24.
[0032] Please see Figure 2In this embodiment of the invention, the repair auxiliary mechanism 57 includes a concave seat 571 disposed between the upper sides of two limiting plates 51. An adjustment servo motor 572 is installed on the inner top side of the concave seat 571. The output shaft of the adjustment servo motor 572 is connected to a threaded rod 573 at the outer top side of the concave seat 571. A limiting seat 574 is screwed onto the outside of the threaded rod 573. A connecting rod 575 is hinged to one end of the limiting seat 574 away from the threaded rod 573. The connecting rod 575 is hinged to the upper part of the hollow rod 52 at one end away from the limiting seat 574.
[0033] In the above scheme: First, the cylinder 4 is rotated to drive the lifting rod 2 to rotate, so that the suction cup 55 faces the direction of the sheet metal depression. Then, the lifting servo motor 25 drives the main bevel gear 26 to rotate, the main bevel gear 26 drives the driven bevel gear 24 that meshes with it to rotate, the driven bevel gear 24 drives the screw 23 to rotate, and the screw 23 drives the threaded sleeve 22 to move longitudinally. The height of the suction cup 55 is adjusted so that it corresponds to the depression. After it is aligned, the servo motor 572 is adjusted to drive the threaded rod 573 to rotate. The threaded rod 573 drives the limit seat 574 to move longitudinally. The limit seat 574 will cause the connecting rod 575 to drive the hollow rod 52 to rotate, thereby adjusting the angle of the suction cup 55 or the grinding wheel 583 so that it is aligned with the depression, which facilitates better repair work on the depression.
[0034] Example 3 differs from Example 1 in that:
[0035] Please see Figure 2-3 In this embodiment of the invention, the grinding mechanism 58 includes a second moving shaft 581 that is laterally slidably disposed inside the hollow rod 52. One end of the second moving shaft 581 extends out of the hollow rod 52 near the end of the limiting plate 51 and is connected to a driven gear 582. The end of the driven gear 582 away from the second moving shaft 581 is connected to a grinding wheel 583. A grinding motor 584 is mounted on the upper part of the end of the second moving shaft 581 away from the hollow rod 52. The output shaft of the grinding motor 584 is connected to a main gear 585, which meshes with the driven gear 582. The other end of the second moving shaft 581 is located inside the hollow rod 52 and is connected to a first rack 586. The first rack 586 is located above the drive gear 510 and meshes with it.
[0036] In the above scheme: the rotary cylinder 4 drives the lifting rod 2 to rotate 180 degrees, so that the grinding wheel 583 is aligned with the recessed area. At the same time, the displacement servo motor 59 works, so that the drive gear 510 drives the first rack 586 to move. The first rack 586 drives the second moving shaft 581 to move. At the same time, under the operation of the adjustment servo motor 572, the angle of the grinding wheel 583 is adjusted. Then, the grinding wheel 583 contacts the recessed area. After contact, the grinding motor 584 drives the main gear 585 to rotate. The main gear 585 drives the driven gear 582 that meshes with it to rotate. The driven gear 582 drives the grinding wheel 583 to rotate. The grinding wheel 583 polishes the recessed area.
[0037] Example 4 differs from Example 1 in that...
[0038] Please see Figure 1 In this embodiment of the invention, the painting mechanism 6 includes a paint storage tank 61 disposed on one side of the lifting rod 2. A pump is disposed inside the paint storage tank 61. The output end of the pump is connected to a paint delivery pipe 62. The other end of the paint delivery pipe 62 is connected to an air inlet 561.
[0039] In the above scheme: the prepared paint is poured into the paint storage tank 61, the lifting rod 2 is rotated 180 degrees, the suction cup 55 is aligned with the dented area, and then the pump in the paint storage tank 61 draws the paint into the hollow annular body 563, and then sprays it out from the nozzle 564 towards the dented repair area, finally completing the sheet metal dent repair work.
[0040] Working principle: First, the cylinder 4 rotates to drive the lifting rod 2 to rotate, so that the suction cup 55 faces the recessed part of the sheet metal. Then, the lifting servo motor 25 drives the main bevel gear 26 to rotate. The main bevel gear 26 drives the meshing slave bevel gear 24 to rotate. The slave bevel gear 24 drives the screw 23 to rotate. The screw 23 drives the threaded sleeve 22 to move longitudinally, adjusting the height of the suction cup 55 to correspond to the recessed part. After correspondence, the servo motor 572 is adjusted to drive the threaded rod 573 to rotate. The threaded rod 573 drives the limit seat 574 to move longitudinally. The limit seat 574 will cause the connecting rod 575 to drive the hollow rod 52 to rotate, thereby adjusting the angle of the suction cup 55 to align it with the recessed part.
[0041] After alignment, the displacement servo motor 59 drives the drive gear 510 to rotate, the drive gear 510 drives the second rack 511 meshing with it to move, the second rack 511 drives the first moving shaft 53 to move, so that the suction cup 55 is attached to the sheet metal, and the recessed part is located in the suction cup 55. Then the hot air blower 565 works and opens the valve 562. Hot air enters the hollow annular body 563 through the air pipe 566, and then sprays out from the nozzle 564, spraying towards the recessed part to soften it.
[0042] After the sheet metal is softened, valve 562 is closed and vacuum pump 512 is activated to evacuate the inside of cylinder 54, so that suction cup 55 can firmly adhere to the sheet metal. Then, displacement servo motor 59 continues to work, causing the first moving shaft 53 to move away from the sheet metal. In this way, suction cup 55 will stretch the recessed part and flatten it. After flattening, vacuum pump 512 is degassed, so that suction cup 55 no longer adheres to the sheet metal.
[0043] After leveling, the rotary cylinder 4 drives the lifting rod 2 to rotate 180 degrees, aligning the grinding wheel 583 with the recessed area. At the same time, the displacement servo motor 59 is activated, causing the drive gear 510 to drive the first rack 586 to move. The first rack 586 drives the second moving shaft 581 to move. Simultaneously, under the operation of the adjustment servo motor 572, the angle of the grinding wheel 583 is adjusted. Then, the grinding wheel 583 contacts the recessed area. After contact, the grinding motor 584 drives the main gear 585 to rotate. The main gear 585 drives the meshing driven gear 582 to rotate. The driven gear 582 drives the grinding wheel 583 to rotate, and the grinding wheel 583 polishes the recessed area.
[0044] After polishing, the prepared paint is poured into the paint storage tank 61. The lifting rod 2 is rotated 180 degrees again so that the suction cup 55 is aligned with the dented area. Then, the pump in the paint storage tank 61 draws the paint into the hollow annular body 563, and then sprays it out from the nozzle 564 onto the dented repair area, thus completing the sheet metal dent repair work.
[0045] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
