[0001] The present invention relates to the technical field of aluminum alloy profile production and processing, and particularly to an end drilling system and method for aluminum alloy door and window frame profiles. Background Art

[0002] During the production of aluminum alloy door and window frame profiles, it is necessary to spray resin on the surface of the long strip profiles to improve their surface hardness and wear resistance, which can effectively extend the service life of the aluminum alloy profiles. To spray resin on the surface of the aluminum alloy door and window frame profiles, it is necessary to drill a hole at one end of the profile first, then hang the hook on the conveyor line in the hole drilled at the end of the profile, and finally send the profile into the spraying chamber by the conveyor line for surface spraying.

[0003] However, in the prior art, during the processing and production of aluminum alloy door and window frame profiles, the drilling of the ends of aluminum alloy door and window frame profiles is usually completed manually. When drilling, the operator manually holds the end of the profile, and then drills with a handheld drill, resulting in low drilling efficiency, long time consumption, and not only is it easy to cause safety accidents through manual drilling operations, but also the drilling accuracy is poor, which easily leads to a reduction in the quality of the later products.

The installation is convenient and fast, easy to disassemble and assemble quickly. At the same time, the processed profile can be conveniently unloaded through the gap between the two positioning strips.

[0018] The method for drilling the end of the aluminum alloy door and window frame profile is as follows: S1: Place the aluminum alloy door and window frame profile to be processed on the first conveyor belt on the top side of the loading seat. Then, driven by the driving motor, the aluminum alloy door and window frame profile is conveyed from the left end of the loading seat to the left end of the drilling table.

When the profile at the rightmost end approaches the limit frame and meets five profiles, the air cylinder pushes the drilling machine box and the positioning plate to move. Then, the top side of the profile is positioned and fixed through the positioning plate. Then the drilling machine box continues to move, so that the drill bit approaches the profile. Then, driven by the drilling motor, the corresponding five gears and the drill bit rotate, so as to perform positioning drilling on the profile.

When the present invention then performs drilling processing, the profile is placed on the first conveyor belt on the top side of the feeding seat. Then, under the drive of the drive motor, the profile continuously moves and enters the drilling table, which is convenient for feeding. After the drilling is completed, the positioning plate and the drilling machine case move upward under the action of the cylinder, causing the profile to continue moving. At this time, the limit frame adjusts its expansion and contraction as the profile moves. Until the limit plate on the limit frame aligns with the positioning strip, it is convenient for the processed profile to be discharged through the gap between the two positioning strips and fall on the top side of the second conveyor belt.

[0030] The method for drilling the end of the aluminum alloy door and window frame profile is as follows: S1: Place the aluminum alloy door and window frame profile to be processed on the first conveyor belt 1001 on the top side of the loading seat 10.

[0031] When in use, place the drilling table 8 inside the fixing frame 1, and then use bolts to connect and fix it. Then, place the loading seat 10 at the left end of the drilling table 8. Then rotate the first clamping plate 1002 to engage with the fixing bolt 804, and then use a nut to connect and fix with the fixing bolt 804 through thread. Then, use the same method to place the unloading seat 11 at the right end of the drilling table 8, rotate the second clamping plate 1102, and then use a nut to connect and fix it. The installation is convenient and fast, facilitating quick disassembly and assembly. Then, when performing drilling, place the profile on the first conveyor belt 1001 on the top side of the loading seat 10. Then, under the drive of the drive motor, the profile continuously moves and enters the drilling table 8, facilitating loading. At this time, as the profile is continuously conveyed, the profile approaches the limiting plate 904. At the same time, the inductor at the bottom side of the lug 702 is used for induction and counting. When five profiles are sensed, the air cylinder 2 pushes the drilling machine case 3 and the positioning plate 7 to move. Then, the top side of the profile is positioned and fixed by the positioning plate 7. Then, the drilling machine case 3 continues to move under the action of the air cylinder 2, causing the drill bit 6 to approach the profile. Then, under the action of the drilling motor 4, the corresponding five gears 5 and the drill bit 6 are driven to rotate, thereby performing positioning drilling on the profile, which is beneficial to improving the drilling efficiency and accuracy and further improving the product processing quality. Then, after the drilling is completed, the positioning plate 7 and the drilling machine case 3 move upward under the action of the air cylinder 2, causing the profile to continue to move. At this time, the limiting frame 9 adjusts its length as the profile moves. Until the limiting plate 904 on the limiting frame 9 aligns with the positioning bars 1103, it is convenient for the processed profile to be discharged through the gap between the two positioning bars 1103 and fall on the top side of the second conveyor belt 1101.

Then, the unprocessed profile is used to push the processed profile to continue moving to the right end. At this time, the limit frame (9) is telescopically adjusted as the profile moves. Until the limit plate (904) on the limit frame (9) is aligned with the positioning bars (1103), it is convenient for the processed profile to be discharged through the gap between the two positioning bars (1103) and fall on the top side of the second conveyor belt (1101). Then, driven by the drive motor, the second conveyor belt (1101) rotates to convey the processed profile to the right end.
