Description

Technical Field

[0001] This utility model relates to the field of aluminum profile processing technology, and more specifically to a multi-station aluminum profile drilling machine. Background Technology

[0002] Chinese patent discloses a multifunctional automatic aluminum profile drilling machine (patent number: 2022202413333), including a worktable. Four feet are fixed at the four corners of the worktable's bottom. Clamping seats are provided on both sides of the top of the worktable. A fixed base is horizontally fixed to the top of the rear end of the worktable, and a support is provided on the top of the fixed base. After drilling at the current position, the drill bit assembly can be retracted by a cylinder. Then, a second servo motor can start the output shaft to drive a second screw to rotate. The rotation of the second screw causes a second threaded sleeve connected externally to move left and right outside the screw, simultaneously moving the support and the drill bit assembly at one end of the support. This facilitates adjustable drilling at different positions on the aluminum profile, solving the problem of inconvenient adjustable drilling at different positions on the aluminum profile. The technical solution disclosed in this Chinese patent has the following problems: First, it does not have an automatic feeding function and requires manual feeding; second, when multiple drilling is required, the drill bit assembly needs to be driven to move multiple times to drill, and the drilling efficiency needs to be improved.

[0030] Please refer to Figures 1 to 5 This utility model provides a multi-station aluminum profile drilling machine, such as... Figure 1As shown, it includes a workbench 10, a multi-station drilling mechanism 20 that can be lifted and mounted on the workbench 10, a belt conveyor mechanism 30 fixed on the workbench 10 for conveying aluminum profiles, a material support assembly 40 for receiving aluminum profiles conveyed from the conveyor mechanism 30 and sending them directly below the multi-station drilling mechanism 20, an alignment assembly 50 mounted on the workbench 10 for organizing the aluminum profiles received by the material support assembly 40, a clamping assembly 60 for pressing the aluminum profiles received by the material support assembly 40, and a straightening assembly 70 mounted on the workbench 10 for straightening the aluminum profiles and conveying them to the belt conveyor mechanism 30. This utility model is mainly aimed at aluminum profiles with relatively small cross-sections and easy bending. In actual use, the aluminum profiles after being cut to a fixed length are bent. Therefore, the bent aluminum profiles need to be straightened before drilling. It can also automatically drill holes in aluminum profiles that do not require straightening. Once the drilling is complete, the aluminum profiles can be removed from the material support assembly by a subsequent robotic arm.

[0031] In this embodiment, as Figure 2 , Figure 3 As shown, the multi-station drilling mechanism 20 includes a gantry frame 21 fixed on the workbench 10, a lifting frame 22 that can be raised and lowered in the gantry frame 21 via first guide rail pair A at both ends, a lifting cylinder 24 mounted on the workbench 10 via a fixed base 23 for driving the lifting frame 22 to rise and fall on the gantry frame 21, and multiple CNC drilling machines 25 mounted on the lifting frame 22. In this embodiment, the lifting frame 22 includes two opposing sliding plates 221, a front side plate 222 connected between the two sliding plates 221, and a drive plate 223 connected to the two sliding plates 221. The two sliding plates 221 are fixed to the sliders of the first guide rail pair A, so that the lifting frame 22 can rise and fall in the gantry frame 21. The cylinder shaft of the lifting cylinder 24 is fixed to the drive plate 223, so that the lifting cylinder 24 drives the lifting frame 22 to rise and fall when it works.

[0032] like Figure 3 As shown, in some embodiments, the plurality of CNC drilling machines 25 are mounted on the lifting frame 22 via two second guide rail pairs B. The two second guide rail pairs B are fixed on the front side plate 222, and each CNC drilling machine 25 is provided with a corresponding number of sliders. In the figure, only one slider is shown for each second guide rail pair B, and each CNC drilling machine 25 is fixed on the corresponding slider. It is only necessary to enable the CNC drilling machine 25 to move on the two second guide rail pairs B and to be locked, thereby achieving the effect of drilling holes at different positions on the aluminum profile.

[0033] In this embodiment, as Figure 4As shown, the CNC drilling machine 25 includes a drilling machine 252 and an electric slide 251 for driving the drilling machine 252 to move up and down. The electric slide 251 includes a mounting plate 251A, a slide 251B mounted on the mounting plate 251A via two third guide rail pairs C, a lead screw pair 251C located between the two third guide rail pairs C, and a servo motor 251D mounted on the mounting plate 251A with its motor shaft connected to the lead screw pair 251C via a lead screw drive. The slide 251B is fixed to the nut of the lead screw pair 251C (the nut of the lead screw pair is not shown in the figure). The drilling machine 252 is fixed on the slide 251B. The servo motor drives the lead screw to rotate, thereby driving the slide to move on the mounting plate, thus achieving the effect of the electric slide 251 driving the drilling machine 252 to move. The electric slide 251 can achieve the effect of multiple CNC drilling machines drilling holes of different depths on aluminum profiles. The drilling machine 252 is a commonly used accessory in the art, including a motor and a drill bit mounted on the motor shaft. It is worth mentioning that the lead screw assembly 251C includes a lead screw and a nut sleeved on the lead screw; the lead screw assembly is a commonly used accessory in the art or mechanical field.

[0034] In this embodiment, as Figure 5 , Figure 6 As shown, the belt conveyor mechanism 30 includes a conveyor frame 31, a belt conveyor line 32 rotatably mounted inside the conveyor frame 31, a pressing roller 33 movably mounted inside the conveyor frame 31 and movable toward the belt conveyor line 32, a pressing cylinder 34 for pushing the pressing roller 33 to move, and a conveyor motor 35 for driving the belt conveyor line 32 to rotate. The belt conveyor line 32 includes two pulleys 321 rotatably mounted inside the conveyor frame 31 and a belt 322 sleeved on the two pulleys 321. The motor shaft of the conveyor motor 35 is connected to one of the pulleys 321 so that the conveyor motor 35 drives the belt to rotate. When the aluminum profile enters the belt 322, the pressing cylinder 34 pushes the pressing roller 33 to press the aluminum profile onto the belt 322. When the belt rotates, it drives the aluminum profile to move, thus achieving the effect of conveying the aluminum profile.

[0035] In this embodiment, as Figure 3 As shown, the material support assembly 40 includes a material rack 41 movably mounted on the worktable 10 and a push cylinder 42. The material rack 41 is movably mounted on the worktable 10 via multiple fourth guide rail pairs D. The push cylinder 42 is fixed on the worktable 10, and its cylinder shaft is fixed to the material rack 41, so as to achieve the purpose of pushing the material rack 41 to move on the worktable 10 by the push cylinder 42. In this embodiment, as shown... Figure 1As shown, the alignment assembly 50 includes an alignment cylinder 51 and an alignment plate 52 fixed on the cylinder shaft of the alignment cylinder 51. The alignment assembly 50 is installed directly below the CNC drilling machine 25. When the material rack 41 is dragged to the direct under the CNC drilling machine 25 by the push cylinder, the alignment plate 52 pushes the aluminum profile on the material rack to completely enter the material rack. When there are multiple aluminum profiles supported on the material rack, the alignment plate can align the ends of the multiple aluminum profiles to facilitate the clamping assembly 60 to clamp the aluminum profiles on the material rack. After the clamping assembly clamps the aluminum profiles, the CNC drilling machine 25 can perform drilling operations on the aluminum profiles.

[0036] In this embodiment, as Figure 7 As shown, the clamping assembly 60 includes a clamping frame 61 fixed on the worktable 10, a clamping cylinder 62 movably mounted on the clamping frame 61, and a clamping structure 63 movably mounted on the clamping frame 61 and movably connected to the cylinder shaft of the clamping cylinder 62. The clamping structure 63 includes a pivot seat 631 mounted on the clamping frame 61, a movable frame 632 whose bottom end is movably mounted on the lower part of the pivot seat 631 via a rotating shaft, a clamping arm 633 movably connected to the pivot seat 631 via a rotating shaft, and a clamping arm 633 mounted on the clamping frame 61. The clamping head 634 on the arm 633, the top of the pivot seat 631 is movably connected to the cylinder shaft of the clamping cylinder 62, and a lifting member 635 is movably connected between the top of the pivot seat 631 and the middle of the clamping arm 633. The movable frame 632 is pushed to swing on the pivot seat 631 by the clamping cylinder 62, and then the clamping arm 633 is driven to swing on the pivot seat 631 by the movable frame 632, so as to realize the clamping head 634 installed on the clamping arm to clamp the aluminum profile located on the material rack.

[0037] In some embodiments, such as Figure 8 As shown, the clamping assembly 60 consists of a clamping cylinder 62A inverted on the worktable 10 via a mounting bracket 61A, a clamping arm 63A mounted on the clamping cylinder 62A, and a clamping head 64A mounted on the clamping arm 63A. The clamping cylinder 62A pushes the clamping head 64A to clamp the aluminum profile located on the material rack.

[0038] like Figure 9 , Figure 10As shown, in this embodiment, the straightening assembly 70 includes a main straightening mechanism 71 and two auxiliary straightening mechanisms 72 located at the front and rear ends of the main straightening mechanism 71. The main straightening mechanism 71 includes a straightening plate 711 fixed vertically to the worktable 10, an active straightening wheel 712 located on one side of the straightening plate 711, a straightening motor 713 fixed to the back of the worktable 10 and drivenly connected to the active straightening wheel 712, a pressure wheel 714 located on the other side of the straightening plate 711, and a pressure cylinder 715 fixed to the worktable 10. The pressure wheel 714 is mounted on the worktable 10 via a fifth guide rail pair E. The pressure wheel 714 can... The slider of the fifth guide rail pair E is rotatably mounted on it. The cylinder shaft of the pressure cylinder 715 is fixed to the slider of the fifth guide rail pair E. The straightening plate 711 is provided with a material groove 711A. The material groove 711A is provided with a notch 711B corresponding to the active straightening wheel 712. When the aluminum profile enters the material groove, the pressure wheel is located on one side of the aluminum profile, while the active straightening wheel is located on the other side of the aluminum profile. The active straightening wheel can contact the entering aluminum profile through the notch. The pressure cylinder pushes the pressure wheel to move towards the active straightening wheel. Through the pressure of the pressure wheel on the aluminum profile, the bent part of the aluminum profile is straightened during the conveying process, thereby playing a straightening role.

[0039] In this embodiment, the secondary straightening mechanism 72 includes a fixed plate 721, a shaft plate 722 fixed on the fixed plate 721, a row of force-receiving wheels 723 rotatably fixed on the fixed plate 721, a movable frame 724 movably inserted into the shaft plate 722, and a row of pressure wheels 725 facing the force-receiving wheels 723 and rotatably mounted on the movable frame 724. A spring 726 is provided between the movable frame 724 and the shaft plate 722. When the aluminum profile enters between the pressure wheel and the force-receiving wheel, the movable frame 724 will be subjected to pressure in the direction of the force-receiving wheel under the action of the spring. The slightly bent aluminum profile will be straightened under the combined action of the pressure wheel and the force-receiving wheel. The purpose of setting two secondary straightening mechanisms is to obtain a better straightening effect. In some embodiments, only one secondary straightening mechanism is needed.

[0040] It is worth mentioning that the first, second, third, fourth, and fifth guide rail pairs mentioned in this application are commonly used accessories in the field of machinery, and all include guide rails and sliders mounted on the guide rails. The aforementioned lifting frame, CNC drilling machine, slide table, and material rack are all fixed to the sliders of their mating guide rail pairs, thereby achieving the effect of moving the aforementioned accessories. Those skilled in the art can understand how to achieve the purpose of moving the corresponding accessories through guide rail pairs.

In addition, the straightening assembly of the present invention can realize the drilling of aluminum profiles after straightening.
