Description

Technical Field

[0001] This utility model relates to the field of cutting and drilling milling machine technology, specifically an automatic aluminum cutting and drilling milling machine with automatic loading and unloading. Background Technology

[0002] Aluminum profiles are alloy materials with aluminum as the main component, and are commonly used in building doors and windows, curtain walls, and interior and exterior decoration.

[0003] Cutting and milling machines are commonly used machining equipment. In traditional technology, the cutting, drilling, and milling (grooving) of strip aluminum profiles usually require different equipment to process them separately. However, this requires operators to receive and transfer the aluminum profiles in the middle, which reduces processing efficiency (because of the long downtime) and increases the labor burden on workers. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic aluminum cutting and milling machine with automatic loading and unloading, which adopts an integrated approach to achieve multiple functions in one machine, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides: An automatic aluminum cutting and milling machine includes a feeding bin, a worktable at the discharge port of the feeding bin, and first grooves at the two edges of the upper surface of the worktable. A vertical plate is positioned above the first grooves. A first ball screw assembly for driving the vertical plate laterally is installed within the first groove. A connecting beam is positioned between the tops of the two vertical plates, and a second groove is formed on the side wall of the connecting beam. A connecting block is positioned beside the second groove. A second ball screw assembly for driving the connecting block laterally is installed in the second groove. A drilling head, a milling head, and a cutting head capable of independent lifting and lowering are positioned below the connecting block. A conveyor belt is installed within the worktable. A first clamping rod and a second clamping rod are positioned on the upper surface of the conveyor belt for clamping and limiting aluminum profiles. A receiving gap for accommodating a cutting disc is provided between the first clamping rod and the second clamping rod. A waste collection box is positioned at the end of the worktable furthest from the feeding bin, and a screen is installed inside the waste collection box.

[0006] Furthermore, the drill head is connected to the connecting block via a first electric telescopic rod; the milling head is connected to the connecting block via a second electric telescopic rod; and the cutting head is connected to the connecting block via a third electric telescopic rod.

[0007] Furthermore, one end of the second ball screw pair is connected to a first motor, and the bottom of the first motor is connected to a support plate, which is fixedly installed on the upper end of the vertical plate.

[0008] Furthermore, one end of the first ball screw pair is connected to a second motor, and the bottom of the second motor is connected to the upper surface of the waste collection box.

[0009] Furthermore, the end of the conveyor belt away from the feed hopper is positioned above the top opening of the waste collection box.

[0010] Furthermore, a pressure plate is provided at the top of the inner cavity of the conveyor belt; the pressure plate is used to support the aluminum profile upwards.

[0011] Furthermore, the screen is detachably installed on the top of the inner cavity of the waste collection box.

[0012] Furthermore, the feeding hopper is provided with a feeding channel; the feeding channel is provided with feeding wheels for driving the aluminum profile to move.

[0013] The beneficial effects of this utility model are as follows: (1) In this utility model, the drilling head, milling head and cutting head are integrated by using a connecting block. They can be raised and lowered independently to perform corresponding processing operations, thereby avoiding the problem of aluminum profiles being transferred between multiple devices, thus improving work efficiency and reducing manpower burden.

[0014] (2) The first clamping rod and the second clamping rod can clamp the limiting strip aluminum profile to achieve the positioning of the aluminum profile and improve the processing accuracy.

[0015] (3) A gap is provided between the first clamping rod and the second clamping rod to accommodate the cutting disc with a larger diameter, thereby avoiding the problem of the first clamping rod and the second clamping rod being damaged by the cutting disc.

[0016] (4) When the finished part of the aluminum profile is placed above the waste collection box, the finished part will fall downward under its own weight, thereby expanding the cutting groove and breaking the adhesive part. The presence of the adhesive part is to prevent the cutting disc from cutting through the aluminum profile, thereby avoiding the problem of the transmission belt being cut by the cutting disc.

[0017] (5) An elastic connection is formed between the cable and the screen, which forms a buffer when the finished aluminum profile falls onto the screen, thereby reducing noise. The finished aluminum profile and the processing debris fall into the waste collection box together, and are screened by the screen, which facilitates the separate removal of the aluminum profile and the processing debris.

[0018] (6) The cable and the screen form an elastic connection. When the finished part of the aluminum profile falls onto the screen, the screen will shake. The processing debris that was previously stuck / adhered to the surface of the aluminum profile (located in the waste collection box) can be vibrated and fall off, and then pass through the screen and fall to the bottom of the waste collection box.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-2This utility model provides a technical solution: an automatic aluminum cutting and milling machine with loading and unloading, including a feeding bin 1. A worktable 2 is located at the outlet of the feeding bin 1. First grooves 4 are respectively formed at the two edges of the upper surface of the worktable 2. Vertical plates 6 are respectively located above the two first grooves. A first ball screw assembly 5 for driving the vertical plates 6 to move laterally is installed within the first groove 4. The nut of the first ball screw assembly 5 is fixedly connected to the bottom end of the vertical plate 6. The two ends of the screw of the first ball screw assembly 5 are respectively connected to the side wall of the first groove 4 through bearings and bearing seats, thereby stably installing the first ball screw assembly 5 within the first groove 4. The screw of the first ball screw assembly 5 cooperates with the nut; when the screw rotates, it can push the nut and the vertical plate 6 to move laterally synchronously (at the same time, at the same speed, and in the same direction).

[0023] The inner wall of the first groove 4 is provided with a rolling linear guide pair, the length direction of which is parallel to the length direction of the first groove 4. The slider of the rolling linear guide pair is slidably connected to the guide rail. The guide rail of the rolling linear guide pair is fixedly connected to the inner wall of the first groove 4 by bolts, and the slider of the rolling linear guide pair is fixedly connected to the side wall of the vertical plate 6 by bolts.

[0024] The first ball screw assembly 5 has a telescopic sleeve (e.g., a telescopic bellows) fitted around its outer circumference to isolate the screw from external dust and prevent it from jamming with the nut. One end of the telescopic sleeve is sealed to the side wall of the nut using bolts and a sealing ring, and the other end is sealed to the side wall of the bearing housing using bolts and a sealing ring, allowing the telescopic sleeve to extend and retract as the nut moves. Each of the left and right sections of the first ball screw assembly 5 has a telescopic sleeve fitted on it.

[0025] Please see Figures 1-3 A connecting beam 7 is provided between the top ends of the two vertical plates 6, and the two ends of the connecting beam 7 are respectively fixedly connected to the vertical plates 6 by bolts.

[0026] A second groove 20 is provided on the side wall of the connecting beam 7; a connecting block 12 is provided beside the second groove 20; a second ball screw assembly 10 for driving the connecting block 12 to move laterally is installed in the second groove 20. The second ball screw assembly 10 is arranged along the length direction of the second groove 20. The nut of the second ball screw assembly 10 is fixedly connected to the connecting block 12 by bolts. The two ends of the screw of the second ball screw assembly 10 are respectively rotatably inserted into the insertion holes of the end plate of the connecting beam 7 (bearings are installed in the insertion holes, the outer ring of the bearing is fixedly connected to the end plate by bolts, and the inner ring of the bearing is fixedly connected to the end of the screw by bolts). When the screw of the second ball screw assembly 10 rotates, it can push the nut and the connecting block 12 to move laterally; the direction of movement of the connecting block 12 is perpendicular to the direction of movement of the vertical plate 6.

[0027] The second ball screw assembly 10 has a telescopic sleeve (e.g., a telescopic bellows) fitted around its outer circumference to isolate the screw from external dust and prevent it from jamming with the nut. One end of the telescopic sleeve is sealed to the side wall of the nut using bolts and a sealing ring, and the other end is sealed to the side wall of the bearing housing using bolts and a sealing ring, allowing the telescopic sleeve to extend and retract as the nut moves. Each of the left and right sections of the second ball screw assembly 10 has a telescopic sleeve fitted on it.

[0028] Please see Figure 3 The connecting block 12 is partially inserted into the second groove 20. The top and bottom surfaces of the second groove 20 are respectively provided with rolling linear guide pairs, the length direction of which is parallel to the length direction of the second groove 20. The slider of the rolling linear guide pair is slidably connected to the guide rail. The guide rail of the rolling linear guide pair is fixedly connected to the top / bottom surface of the second groove 20 by bolts, and the slider of the rolling linear guide pair is fixedly connected to the top / bottom surface of the connecting block 12 by bolts.

[0029] Please see Figure 2 Below the connecting block 12 are independently movable drill head 13, milling head 14, and cutting head 15. Drill head 13 is connected to connecting block 12 via a first electric telescopic rod 131; milling head 14 is connected to connecting block 12 via a second electric telescopic rod 141; and cutting head 15 is connected to connecting block 12 via a third electric telescopic rod 151. The first electric telescopic rod 131 drives the drill head 13 to move vertically; the second electric telescopic rod 141 drives the milling head 14 to move vertically; and the third electric telescopic rod 151 drives the cutting head 15 to move vertically.

[0030] Please see Figure 2 When drilling is required on the aluminum profile 21, the drill head 13 needs to be lowered, the milling head 14 needs to be raised, and the cutting head 15 needs to be raised; when milling is required on the aluminum profile 21, the drill head 13 needs to be raised, the milling head 14 needs to be lowered, and the cutting head 15 needs to be raised; when cutting is required on the aluminum profile 21, the drill head 13 needs to be raised, the milling head 14 needs to be raised, and the cutting head 15 needs to be lowered; thus avoiding interference.

[0031] The drill head 13 includes a drilling tool at the bottom; the milling head 14 includes a milling tool at the bottom; and the cutting head 15 includes a cutting disc 1511 at the bottom.

[0032] Please see Figure 4 and Figure 5A conveyor belt 19 is installed inside the workbench 2. The upper surface of the conveyor belt 19 is provided with first clamping rods 22 and second clamping rods 23 for clamping and limiting the aluminum profile 21. The first clamping rods 22 are arranged in pairs to clamp the two side walls of the aluminum profile 21 respectively; the second clamping rods 23 are also arranged in pairs to clamp the two side walls of the aluminum profile 21 respectively. The two first clamping rods 22 and the two second clamping rods 23 clamp and limit the aluminum profile 21 at the center position of the upper surface of the conveyor belt 19 for initial positioning during machining.

[0033] Please see Figure 4 and Figure 5 Please see Figure 4 and Figure 5 A receiving gap 210 is provided between the first clamping rod 22 and the second clamping rod 23 to accommodate the cutting disc 1511. The diameter of the cutting disc 1511 is larger than the width of the aluminum profile 21, so the receiving gap 210 is needed to make way for it and prevent the cutting disc 1511 from hitting the first clamping rod 22 and the second clamping rod 23.

[0034] Reference Figure 5 The inner wall of the receiving cavity of the worktable 2 is equipped with a first linear actuator 221 and a second linear actuator 231. The fixed end of the first linear actuator 221 is fixedly connected to the worktable 2 by bolts, and its output shaft is fixedly connected to the first clamping rod 22 by bolts. The fixed end of the second linear actuator 231 is fixedly connected to the worktable 2 by bolts, and its output shaft is fixedly connected to the second clamping rod 23 by bolts. The two first linear actuators 221 are connected to the first clamping rod 22 in a π-shape; the two second linear actuators 231 are connected to the second clamping rod 23 in a π-shape. The first linear actuator 221 is used to drive the first clamping rod 22 to move laterally, thereby clamping / releasing the aluminum profile 21; the second linear actuator 231 is used to drive the second clamping rod 23 to move laterally, thereby clamping / releasing the aluminum profile 21. Both the first linear actuator 221 and the second linear actuator 231 are electric actuators.

[0035] A telescopic sleeve (e.g., a telescopic bellows) is fitted on the output shaft of the first linear actuator 221. One end of the telescopic sleeve is sealed and fixedly connected to the end face of the housing of the first linear actuator 221 by bolts and a sealing ring, and the other end is sealed and fixedly connected to the side wall of the first clamping rod 22 by bolts and a sealing ring.

[0036] A telescopic sleeve (e.g., a telescopic bellows) is fitted on the output shaft of the second linear actuator 231. One end of the telescopic sleeve is sealed and fixedly connected to the end face of the housing of the second linear actuator 231 by bolts and a sealing ring, and the other end is sealed and fixedly connected to the side wall of the second clamping rod 23 by bolts and a sealing ring.

[0037] Please see Figure 2One end of the second ball screw assembly 10 is connected to the first motor 8. The output shaft of the first motor 8 is coaxially and fixedly connected to one end of the screw of the second ball screw assembly 10 (e.g., by bolts and keys). The bottom of the housing of the first motor 8 is fixedly connected to a support plate 9 by bolts. The support plate 9 is fixedly installed on the upper end of the side wall of the vertical plate 6.

[0038] Please see Figure 2 One end of the first ball screw assembly 5 is connected to a second motor 16. The output shaft of the second motor 16 is coaxially and fixedly connected to one end of the first ball screw assembly 5 (e.g., by bolts and keys). The bottom of the housing of the second motor 16 is fixedly connected to the upper surface of the waste collection box 3 by bolts.

[0039] Please see Figure 6 The conveyor belt 19 is installed inside the receiving cavity on the top surface of the workbench 2. The conveyor belt 19 includes a belt body, two belt rollers, and a drive motor. The two belt rollers are arranged in parallel and are rotatably connected to the side wall of the receiving cavity of the workbench 2. The drive motor is located on the outer side wall of the workbench 2, and the output shaft of the drive motor is connected to one of the belt rollers away from the feed hopper 1 through a gear reducer (the gear reducer is installed inside the workbench 2). The drive motor can drive the belt roller to rotate, thereby driving the belt body to rotate. The housing of the drive motor is fixedly connected to the outer side wall of the workbench 2 by bolts. The belt body is wrapped around and tensioned on the outer surface of the belt rollers, and the two belt rollers are respectively inserted into the two ends of the inner cavity of the belt body.

[0040] Please see Figure 2 , Figure 4 and Figure 5 A waste collection box 3 is provided at the end of the workbench 2 furthest from the feed bin 1. A screen 17 (made of steel plate with perforated holes) is installed inside the waste collection box 3. The conveyor belt 19 moves the aluminum profile 21 towards the waste collection box 3, causing the finished portion of the aluminum profile 21 and processing debris to fall into the waste collection box 3 simultaneously. The debris passes through the perforated holes and falls to the bottom of the waste collection box 3, while the finished portion of the aluminum profile 21 is blocked by the screen 17, thus separating the product from the waste.

[0041] The connecting beam 7, drill head 13, milling head 14 and cutting head 15 are all located above the upper surface of the conveyor belt 19.

[0042] Please see Figure 5 and Figure 6 When the end of the conveyor belt 19 away from the feed bin 1 is placed above the top opening of the waste collection box 3, the finished part of the aluminum profile 21 can fall into the waste collection box 3 just as it is moved to the end of the conveyor belt 19.

[0043] Please see Figure 4The screen 17 is detachably installed on the top of the inner cavity of the waste collection box 3. The screen 17 is connected to the inner cavity of the waste collection box 3 by a cable 171; the outer edge of the screen 17 is provided with a first lifting lug (e.g., fixed by welding), and the inner side wall of the waste collection box 3 is provided with a second lifting lug (e.g., fixed by welding); one end of the cable 171 is detachably connected to the first lifting lug by a self-locking hook, and the other end is detachably connected to the second lifting lug by a self-locking hook.

[0044] Please see Figure 5 and Figure 6 A pressure plate 191 is provided at the top of the inner cavity of the conveyor belt 19; the pressure plate 191 is used to support the aluminum profile 21 upwards. The pressure plate 191 is placed in the receiving cavity and its two ends are fixedly connected to the worktable 2 by bolts. During machining, a reaction force (i.e., an upward supporting force) needs to be provided to the pressure plate 191 and the aluminum profile 21 to increase friction and realize drilling, milling and cutting, avoiding the problem that the conveyor belt 19 cannot provide sufficient reaction force to the aluminum profile 21. The top of the conveyor belt 19 is pressed against the upper surface of the pressure plate 191 because it bears the weight of the aluminum profile 21.

[0045] Reference Figure 7 To avoid puncturing the conveyor belt 19, the drill head 13 is limited to processing the top surface of the aluminum profile 21 (e.g., by controlling the stroke of the output shaft of the first electric telescopic rod 131), and the milling head 14 is limited to processing the top surface of the aluminum profile 21 (e.g., by controlling the stroke of the output shaft of the second electric telescopic rod 141). When the cutting head 15 cuts the aluminum profile 21, an adhesive portion 2111 needs to be left at the bottom end of the formed cutting groove 211. The adhesive portion 2111 must not be cut off to avoid the cutting disc 1511 from damaging the belt.

[0046] Reference Figure 8 When the finished portion of the aluminum profile 21 is placed above the waste collection box 3, the finished portion will fall downwards under its own weight, thereby expanding the cutting groove 211 and simultaneously breaking the adhesive portion 2111 (if necessary, manual assistance is used to break it). After the adhesive portion 2111 is broken, burrs will be generated, which need to be removed by a grinder during subsequent processing.

[0047] Reference Figure 1 The feed bin 1, workbench 2, and waste collection bin 3 are all placed on the floor of the processing workshop.

[0048] Reference Figure 9The feeding hopper 1 is equipped with a feeding channel; the feeding channel is equipped with feeding wheels 102 for driving the movement of aluminum profiles 21. Several support columns 101 are erected at the bottom of the inner cavity of the feeding channel, and the bottom ends of the support columns 101 are fixedly connected to the feeding hopper 1 by bolts; the feeding wheels 102 are rotatably mounted on the top of the support columns 101 via bearings and bearing seats. Each support column 101 has a feeding wheel 102 mounted on its top, and the feeding wheels 102 are arranged in a straight line. An annular groove is provided in the center of the circumference of the feeding wheel 102. The aluminum profiles 21 are secured in the annular groove, thus stably pressing them onto the feeding wheels 102 and preventing them from falling laterally off the feeding wheels 102.

[0049] A feed motor is mounted on the top surface of the support column 101. The bottom surface of the feed motor housing is bolted to the top surface of the support column 101, and the front end of the feed motor housing is bolted to the side wall of the bearing seat. The output shaft of the feed motor is inserted into the loading wheel 102 at a new position and bolted to it. The feed motor drives the loading wheel 102 to rotate, thereby pushing the aluminum profile 21 towards the conveyor belt 19. The aluminum profile 21 has a low density and is therefore lightweight, allowing the user to manually handle it and insert it into the loading channel, pressing it against the loading wheel 102. The speed of the feed motor is matched with the speed of the drive motor, thus matching the linear speed of the belt with the linear speed of the annular groove, enabling synchronous movement of the aluminum profile 21 and preventing slippage. The single travel distance of the aluminum profile 21 is controlled by the drive motor and the feed motor.

[0050] The first motor 8, the second motor 16, the drive motor, and the feed motor are all controllable motors (such as servo motors or stepper motors). By inputting electrical signals to the controllable motors through an external controller, the speed, number of revolutions per cycle, and start / stop timing of the controllable motors can be controlled, thereby adapting to the required mechanical actions.

[0051] This utility model also includes an electrical cabinet, which is installed on the floor of the processing workshop. The first motor 8, the second motor 16, the drive motor, the feed motor, the first linear driver 221, the second linear driver 231, the first electric telescopic rod 131, the second electric telescopic rod 141, the third electric telescopic rod 151, the drill head 13, the milling head 14, and the cutting head 15 are respectively connected to the electrical cabinet via wires and signal lines. The electrical cabinet is connected to the external power supply and the external controller (such as a computer or a PLC programmable logic controller) via wires and signal lines. The external controller controls the start and stop of the first motor 8, the second motor 16, the drive motor, the feed motor, the first linear driver 221, the second linear driver 231, the first electric telescopic rod 131, the second electric telescopic rod 141, the third electric telescopic rod 151, the drill head 13, the milling head 14, and the cutting head 15 through the electrical cabinet.

[0052] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
