Description

Technical Field

[0001] This utility model relates to a feeding device for drilling aluminum profile alloys. Background Technology

[0002] Aluminum alloy profiles are widely used in construction, automotive, aerospace, and electronics industries due to their excellent properties such as lightweight, high strength, and corrosion resistance. Drilling is a common processing step in the fabrication of aluminum profiles.

[0003] For drilling long aluminum profiles, especially for continuous drilling of multiple holes, the existing technology relies on manual feeding, which is inefficient and poses certain risks.

[0004] Based on the above problems, we designed an aluminum profile alloy drilling and feeding device that can upgrade existing drilling machines to achieve continuous feeding of long aluminum profiles. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an aluminum profile alloy drilling and feeding device that can upgrade existing drilling machines and realize continuous feeding of long aluminum profiles.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A feeding device for drilling aluminum profile alloys includes an extension plate installed on the side of the drilling machine operating table. The extension plate is equipped with a variable height pressing mechanism near the drilling machine operating table. Two lateral limiting mechanisms are provided at the front and rear of the top of the extension plate.

[0008] Preferably, a support frame is installed at the bottom of the extension plate, away from the drilling machine operating table.

[0009] Preferably, the variable height pressing mechanism includes two support bodies, front and rear. An upward-through groove is provided on the inner side of each support body. A top cover is installed between the tops of the two support bodies. An active slider is slidably fitted on the rear support body, and a passive slider is slidably fitted on the front support body. A connecting bracket is installed between the active and passive sliders. A servo reduction motor is installed on the top of the top cover near the rear end. A screw is installed at the output end of the servo reduction motor, and the screw is inserted into the through groove. A bearing is fitted between the lower end of the screw and the support body. First sliding grooves are provided on both sides of the active slider to engage with the support bodies. A threaded hole for engaging the screw is provided at the top of the active slider. A rotating shaft is rotatably installed on the end of the active slider facing the passive slider. A bearing is fitted between the rotating shaft and the active slider. The passive slider has a through hole passing through the rotating shaft. A servo motor for driving the rotating shaft is installed on the outer end face of the passive slider. Second sliding grooves are provided on both sides of the passive slider to engage with the support bodies. A conveying roller is fixedly installed on the rotating shaft.

[0010] Preferably, a rubber bead is fitted onto the outer wall of the conveying roller.

[0011] Preferably, the surface of the rubber bead is provided with anti-slip grooves distributed in a ring.

[0012] Preferably, mounting grooves are evenly distributed on the surface of the extension plate, the mounting grooves are vertically penetrating, a passive roller is rotatably mounted in the mounting groove, an inner shaft is inserted at the axis of the passive roller, the two ends of the inner shaft are fixed to the mounting groove, and a first bearing is fitted between the inner shaft and the passive roller.

[0013] Preferably, the lateral limiting mechanism includes a side plate, with two or more guide rods welded to the outer end face of the side plate, and vertical frames welded to the top two sides of the extension plate.

[0014] The beneficial effects of this utility model are:

[0015] One advantage is that this device can be upgraded for drilling machines at a low cost.

[0016] Secondly, this device can fix long aluminum profiles by pressing them down with the conveyor rollers and using the side plates on both sides for lateral positioning. During drilling, the aluminum profiles are more stable, avoiding jumping and making the drilling process smoother.

[0017] Thirdly, the aluminum profiles are conveyed by the rotation of the conveyor rollers, realizing automatic feeding, eliminating the need for manual feeding, making operation simpler, and greatly reducing labor intensity.

[0018] Fourthly, the height of the conveyor rollers is variable, which can adapt to the processing needs of aluminum profiles of different thicknesses, making it more adaptable. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] See Figure 1 The aluminum profile alloy drilling and feeding device shown includes an extension plate 1 installed on the side of the drilling machine operating table A. The extension plate 1 is equipped with a variable height pressing mechanism 2 near the drilling machine operating table A. The top of the extension plate 1 is provided with two lateral limiting mechanisms 3 at the front and rear.

[0031] In the above technical solution, the positions of the two lateral limiting mechanisms 3 can be adjusted independently to make adaptive adjustments according to the needs of the drilling position and the width of the aluminum profile.

[0032] The aluminum profile being processed is pressed down by the downward movement of the variable height pressing mechanism 2, and after drilling is completed, it is conveyed again to reach the next drilling position to complete continuous drilling and improve drilling efficiency.

[0033] See Figure 1 As shown, a support frame 11 is installed at the bottom of the extension plate 1, away from the drilling machine operating table A.

[0034] The function of the support frame 11 is to provide support on the ground, making the extension plate 1 more stable.

[0035] See Figure 1 , Figure 2 and Figure 3As shown, the variable height pressing mechanism 2 includes two support bodies 21, one in front and one in rear. A through groove 211 extending upwards is provided on the inner side of each support body 21. A top cover 22 is installed between the tops of the two support bodies 21. An active slider 23 is slidably fitted onto the rear support body 21, and a passive slider 24 is slidably fitted onto the front support body 21. A connecting bracket 25 is installed between the active slider 23 and the passive slider 24. A servo reduction motor 26 is installed near the rear end of the top cover 22. A screw 27 is installed at the output end of the servo reduction motor 26. The screw 27 is inserted into the through groove 211, and its lower end engages with the support body 21. The active slider 23 has first grooves 231 on both sides that mate with the support body 21. The top of the active slider 23 has a threaded hole 232 that mates with the screw 27. A rotating shaft 28 is rotatably mounted on the end of the active slider 23 facing the passive slider 24. A bearing 299 mates with the rotating shaft 28 and the active slider 23. The passive slider 24 has a through hole 241 that passes through the rotating shaft 28. A servo motor 29 that drives the rotating shaft 28 is mounted on the outer end face of the passive slider 24. The passive slider 24 has second grooves 242 on both sides that mate with the support body 21. A conveying roller 281 is fixedly mounted on the rotating shaft 28.

[0036] In the above technical solution, the screw is driven to rotate by a servo reducer motor, which in turn drives the active slider to slide vertically along the support body 21, thereby adjusting the height of the conveying roller 281. The conveying roller 281 is driven to rotate by the servo motor to complete the feeding and unloading of aluminum profiles.

[0037] See Figure 2 As shown, a rubber bead 282 is fitted onto the outer wall of the conveying roller 281.

[0038] The rubber bead 282 is designed to allow for elastic deformation, increasing the contact force with the aluminum profile.

[0039] See Figure 2 As shown, the surface of the rubber bead 282 is provided with anti-slip grooves 283 arranged in a ring.

[0040] The anti-slip groove 283 can increase the anti-slip force, so that the conveyor roller 281 can drive the aluminum profile to move.

[0041] See Figure 4 As shown, mounting grooves 121 are evenly distributed on the surface of the extension plate 1. The mounting grooves 121 extend vertically through the plate. A passive roller 131 is rotatably mounted in the mounting groove 121. An inner shaft 141 is inserted through the axis of the passive roller 131. Both ends of the inner shaft 141 are fixed to the mounting groove 121. A first bearing is fitted between the inner shaft 141 and the passive roller 131.

[0042] The above technical solution adopts the design of passive roller 131, which can roll and rub against the aluminum profile being conveyed, thereby reducing the conveying resistance of the aluminum profile.

[0043] The height of the upper end face of the passive roller 131 is flush with the table surface of the drilling machine operating table.

[0044] See Figure 1 and Figure 5 As shown, the lateral limiting mechanism 3 includes a side plate 31. Two or more guide rods 32 are welded to the outer end face of the side plate 31. Vertical frames 133 are welded to the top two sides of the extension plate 1. The guide rods 32 pass through the vertical frames 133. Locking bolts 134 for fixing the guide rods 32 are installed at the top of the vertical frames 133. The bottom surface of the side plate 31 is higher than the passive roller 131. Multiple first mounting grooves 33 are passed through the surface of the side plate 31. A lateral conveying roller 34 is rotatably installed in the first mounting grooves 33. A first inner shaft 35 is installed at the axis of the lateral conveying roller 34. The upper and lower ends of the first inner shaft 35 are fixed to the first mounting grooves 33. A second bearing is fitted between the first inner shaft 35 and the lateral conveying roller 34.

[0045] In the above technical solution, the lateral conveying roller 24 limits the aluminum profile while reducing friction during conveying.
