[0035] Example 1

[0036] See also Figure 1-Figure 7, this embodiment provides a drilling device for aluminum profile processing, including a workbench 1. A U-shaped plate 3 is fixedly connected to the upper end of the workbench 1. A drilling machine 2 is arranged at the bottom of the U-shaped plate 3. A cylinder 41 is fixedly connected to the top of the workbench 1. The output end of the cylinder 41 is fixedly connected to a mounting plate 42. The drilling machine 2 is fixedly connected to the bottom of the mounting plate 42. A hydraulic chamber A43 is fixedly connected to the upper end of the mounting plate 42. A hydraulic rod A44 is slidably connected inside the lower side port of the hydraulic chamber A43. A roller 45 is arranged at the bottom of the hydraulic rod A44. After the design of the roller 45 realizes the fixation of the aluminum profile, it can still ensure that the aluminum profile can move back and forth, left and right, providing conditions for the central positioning of the aluminum profile. The other end of the hydraulic chamber A43 is fixedly connected to a connecting hose A46. The other end of the connecting hose A46 is fixedly connected to a hydraulic chamber B47. A hydraulic rod B48 is slidably connected inside the other end of the hydraulic chamber B47. The other end of the hydraulic rod B48 is fixedly connected to a toothed plate 49. A mounting shaft 410 is rotatably connected to the bottom of the workbench 1. A transmission gear 411 is fixedly sleeved on the outer wall of the mounting shaft 410. A rectangular plate 412 is fixedly connected to the bottom of the mounting shaft 410. The bottom of the rectangular plate 412 is rotatably connected to a connecting rod 413 through a pin shaft. The other end of the connecting rod 413 is hinged to a moving plate 414. A hydraulic chamber C420 is fixedly connected to the outer wall of the moving plate 414. A hydraulic rod C415 is slidably connected inside the hydraulic chamber C420. A clamping plate 416 is fixedly connected to one end of the hydraulic rod C415. A blowing component 5 and a cooling component 6 are assembled on the upper end of the moving plate 414. A connecting hose B417 is fixedly connected between the transverse hydraulic chamber C420 and the longitudinal hydraulic chamber C420. The cooperation of the hydraulic chamber C420 and the connecting hose B417 realizes the transmission of force. A chute 419 is opened at the upper end of the workbench 1. The lower end of the moving plate 414 is slidably connected inside the chute 419. By setting the chute 419, a moving range is provided for the sliding of the moving plate 414, ensuring the stability of its movement.

[0037] The toothed plate 49 is located on the side of the transmission gear 411 and meshes with it. A spring 418 is movably sleeved on the outer wall of the hydraulic rod A44. The two ends of the spring 418 are respectively fixedly connected to the mounting plate 42 and the mounting seat of the roller 45. The spring 418 can realize the reset of the roller 45 after processing through its elastic force.

[0038] When in use, first place the aluminum profile to be drilled on the upper end of the workbench 1, then start the cylinder 41 to drive the mounting plate 42 to descend, and the hydraulic bin A43 will also descend. Since the roller 45 at the bottom of the hydraulic rod A44 on the lower side of the hydraulic bin A43 is lower than the drilling machine 2, the roller 45 will first contact the top of the aluminum alloy profile. At this time, since the drilling machine 2 has not yet reached a suitable drilling position, the mounting plate 42 will continue to descend, and the roller 45 will squeeze the spring 418 and drive the hydraulic rod A44 to slide toward the inside of the hydraulic bin A43. Then, under the action of the connecting hose A46, the hydraulic rod B48 inside the hydraulic bin B47 will move outward, thereby driving the tooth plate 49 to move, and then the transmission gear 411 meshing therewith will rotate accordingly, thereby driving the mounting shaft 410 to rotate, and then the rectangular plate 412 at the bottom of the mounting shaft 410 will rotate accordingly, thereby driving the aluminum profile through the connecting rod 413 The front, back, left and right movable plates 414 slide toward the middle inside the slide groove 419, and the hydraulic warehouse C420 will move the movable plates 414 along with it and drive the clamping plates 416 to approach the aluminum profile at the same time. Since the length and width of the aluminum profile are not consistent, after the wider two sides are fixed with the clamping plates 416 in the middle of the workbench 1, the other two sides still need to be fixed, and the movable plates 414 continue to move toward the middle. After contacting the aluminum profile, the clamping plates 416 will drive the hydraulic rod C415 connected to it to move toward the inside of the hydraulic warehouse C420 due to the pressure. Then, under the action of the connecting hose B417, the hydraulic warehouse C420 on the side that is not in contact with the aluminum profile will push the hydraulic rod C415 inside it to approach the aluminum profile until the clamping plates 416 on all sides are evenly in contact with the aluminum profile, thereby achieving fixation of the four sides and the top of the aluminum profile. At this time, the drilling machine 2 can drill holes in the aluminum profile by adjusting the height of the drill bit.

By providing the clamping block 511 and the clamping groove 512, it not only ensures that the transmission cylinder 53 slides on the outer wall of the transmission shaft 52, but also does not affect the transmission effect between them. An outer wall of the inclined block 59 is fixedly connected with a guide rail 510, the L-shaped plate 54 is slidably connected to an outer wall of the guide rail 510. The setting of the guide rail 510 can limit the moving direction of the inclined block 59.

[0041] During use, start the motor 51 to drive the transmission shaft 52 to rotate. Then, with the cooperation of the clamping block 511 on the outer part of the transmission shaft 52 and the clamping groove 512 inside the transmission cylinder 53, the transmission cylinder 53 can rotate along with the transmission shaft 52. Then, it can drive the bevel gear A55 at its bottom to rotate. Then, the meshing bevel gear B57 will rotate accordingly, and then drive the rotating shaft 56 to rotate, thereby driving the fan blade 58 to rotate to blow off the residues on the upper end of the workbench 1. When drilling the aluminum profile, the moving plate 414 needs to drive the clamping plate 416 to move towards the middle. Then, the inclined block 59 located at the upper end of one side moving plate 414 will move accordingly, and then the L-shaped plate 54 that fits with it at its upper end will move upwards, and then drive the transmission cylinder 53 to slide on the outer part of the transmission shaft 52, thereby adjusting the heights of the bevel gear A55, the bevel gear B57, the rotating shaft 56 and the fan blade 58, so that the fan blade 58 blows air on the drill bit during drilling to assist the drill bit in cooling down.

[0042] Embodiment 3

[0043] See Figure 1 - Figure x, the cooling component 6 includes a water tank 61, the water tank 61 is fixedly connected to the upper end of the C-shaped plate 3, a water injection port 62 is formed at the top of the water tank 61, a telescopic water delivery pipe 63 is fixedly connected to the bottom of the water tank 61, the other end of the water delivery pipe 63 is fixedly connected with a spray head 64, an upper end of one side moving plate 414 is fixedly connected with a connecting rod 65, and the other end of the connecting rod 65 is fixedly connected with a baffle 67. An activity groove 66 is formed at the top of the C-shaped plate 3, and an outer wall of the connecting rod 65 is slidably connected with the activity groove 66. The cooling component 6 provides a necessary cooling function during the drilling process, reduces the damage caused by the overheating of the drill bit, and ensures the accuracy and efficiency of the aluminum profile processing.

[0044] During use, when drilling holes in the aluminum profile, the movable plate 414 needs to drive the clamping plate 416 to move toward the middle, and the connecting rod 65 fixedly connected to the upper end of the movable plate 414 will also move accordingly. The movement of the connecting rod 65 causes the baffle 67 at the other end to move toward the middle of the workbench 1, thereby exposing the connection between the water tank 61 and the water pipe 63. This change triggers the water flow channel of the system, so that the water inside the water tank 61 flows out smoothly through the water pipe 63, and the water is transported to the nozzle 64 through the water pipe 63, and the nozzle 64 sprays water on the drill bit of the drilling machine 2. This water spraying operation plays an important role in cooling down, helping to cool the drill bit and prevent tool wear or deformation of the aluminum profile surface due to overheating. In addition, water spraying for cooling also helps to remove metal chips generated during the drilling process, ensuring the cleanliness of the processing environment and the smooth progress of the drilling process.
