Description

Technical Field

[0001] This utility model belongs to the field of aluminum profile processing technology, specifically relating to a drilling and milling center for aluminum profile processing. Background Technology

[0002] Aluminum profile processing is based on its unique material properties and wide range of application needs. Aluminum profiles have advantages such as light weight, high strength, corrosion resistance, and ease of processing. These properties make them widely used in many fields such as construction, automobiles, rail transportation, electronics, and machinery. During processing, they can be made into various required shapes and sizes through drilling and milling processes to meet the structural and functional requirements of different products. Aluminum profile drilling and milling centers are high-efficiency equipment specifically designed for aluminum profile processing, with multiple functions such as drilling, milling, cutting, and tapping.

[0003] For example, the existing patent discloses a CNC drilling and milling center for aluminum profiles (publication number CN221134853U), whose technical solution includes a worktable, an adjustment box, and a collection box. A cover box is installed on the upper end of the worktable, and a door is installed at the front end of the cover box. A first threaded rod is rotatably installed inside the cover box, and a first movable block is threaded on the first threaded rod. Two adjustment boxes are symmetrically installed on the upper end of the worktable. A second threaded rod is rotatably installed inside the adjustment box, and a second movable block is threaded on the second threaded rod. A fixed rod is installed on the upper end of the second movable block, and an installation plate is installed at the end of the fixed rod. A rotating shaft is rotatably installed on the side end of the installation plate, and a placement plate is installed at the end of the rotating shaft. A second hydraulic device is symmetrically distributed on the placement plate, and a fixed plate is installed at the end of the hydraulic rod of the second hydraulic device.

[0004] The prior art has shown that aluminum profile processing efficiency is low: firstly, when the aluminum profile is fixed by the fixing plate, the contact pressure between the fixing plate and the aluminum profile is uneven, which may cause slight displacement of the aluminum profile during processing; secondly, when the aluminum profile is flipped, if the flipping angle is not accurately controlled, the position of the aluminum profile may shift after flipping, requiring recalibration before processing can continue, affecting drilling and milling accuracy, and thus affecting efficiency. Therefore, we propose a drilling and milling center for aluminum profile processing to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a drilling and milling center for aluminum profile processing, which can solve the problems mentioned in the background art.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A drilling and milling center for aluminum profile processing includes a worktable. A power supply box and a cooling system are located on the upper end of the worktable. Two L-shaped fixing plates are arranged opposite each other on the left and right sides of the worktable. A drilling and milling head is movably mounted on the top wall of the worktable. A rectangular frame is integrally formed between the two L-shaped fixing plates, and an angle sensor is mounted on the upper surface of the L-shaped fixing plates. A pressure plate is movably mounted on the top wall of the two L-shaped fixing plates, and a pressure sensor is mounted on the lower surface of the pressure plate. A collaborative control unit is located on one side of the worktable. The collaborative control unit includes a PLC base plate, a control unit, a signal processing unit, and an interface unit for controlling the pressure sensor, angle sensor, and drilling and milling head to work collaboratively.

[0008] As a further technical solution of this utility model: one side of the workbench is fixed with a PLC base plate by bolts, and one side of the PLC base plate is used for welding control unit, signal processing unit and interface unit.

[0009] As a further technical solution of this utility model: servo motors are fixed on the left and right inner walls of the workbench, and the output end of each servo motor is fixed to one side of the L fixed plate through a connecting shaft to drive the L fixed plate to rotate.

[0010] As a further technical solution of this utility model: an electric telescopic rod is fixed to the upper surface of the L-fixed plate by a bolt bracket, and the output end of the electric telescopic rod is inserted into the L-fixed plate and fixed to the upper surface of the pressure plate by bolts, and a pressure sensor is embedded in the lower surface of the pressure plate.

[0011] As a further technical solution of this utility model: the top wall of the worktable is fixed with an electric XY axis and the output end of the electric XY axis is fixed with an electric Z axis. The output end of the electric Z axis is fixed with a drilling and milling head through a mounting bracket for controlling the flexible movement of the drilling and milling head.

[0012] As a further technical solution of this utility model: the lower end of the workbench is provided with a through groove and a conical collection groove is welded to the outer edge of the through groove; the cooling system includes a water tank fixed to one side of the workbench; a water pump is provided in the water tank; an electric nozzle is fixed to the output end of the water pump through a corrugated pipe; the electric nozzle is fixed to one side of the drill bit by bolts; and the input end of the water pump is connected to the conical collection groove through a hose.

[0013] The technical effects achieved by this utility model are as follows:

[0014] 1. This utility model discloses a drilling and milling center for aluminum profile processing. By installing a pressure sensor on the lower surface of the pressure plate, the pressure of the pressure plate on the aluminum profile is detected in real time. The pressure sensor transmits the pressure signal to the cooperating control component. The control unit, based on the information processed by the signal processing unit, controls and adjusts the pressure of the pressure plate through the interface unit to ensure uniform pressure on the aluminum profile and avoid slight displacement of the aluminum profile during processing due to uneven pressure. At the same time, the angle sensor on the upper surface of the L-fixed plate monitors the flipping angle of the aluminum profile in real time. After the angle information is transmitted to the cooperating control component, the control unit accurately controls the L-fixed plate to flip the aluminum profile to the accurate angle according to the preset angle, reducing the positional offset after flipping. Therefore, processing can continue without recalibration, ensuring drilling and milling accuracy and improving processing efficiency.

[0015] 2. The present invention provides a drilling and milling center for aluminum profile processing. The center monitors the contact pressure between the pressure plate and the aluminum profile in real time through a pressure sensor. The control unit can determine the clamping status of the aluminum profile based on the pressure change. If the pressure suddenly drops abnormally, the control unit will immediately trigger the protection mechanism, suspend the operation of the drilling and milling head through the interface unit, and start the alarm prompt to avoid processing deviation or equipment damage caused by loosening of the aluminum profile.

[0016] 3. This utility model discloses a drilling and milling center for aluminum profile processing. An angle sensor collects the rotation angle data of the L-shaped fixed plate in real time. The collaborative control component can combine this data with the motion trajectory of the drilling and milling head to perform linkage calculations, predict the processing coordinates after the aluminum profile is flipped, and automatically correct the motion path of the drilling and milling head to achieve seamless connection of multi-angle processing. In addition, the historical angle data of the angle sensor can be stored by the control unit to form a statistical analysis of the aluminum profile flipping angle. When the error of the flipping angle exceeds the threshold multiple times, the system automatically prompts to calibrate and maintain the servo motor or connecting shaft to ensure the stability of long-term processing accuracy.

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description of this utility model is provided in conjunction with embodiments. It should be understood that the following text is only used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figures 1 to 4 As shown, a drilling and milling center for aluminum profile processing includes a worktable 1. A power supply box 2 and a cooling system 6 are provided on the upper end of the worktable 1. Two L-shaped fixing plates 3 are arranged opposite each other on the left and right sides inside the worktable 1. A drilling and milling head 5 is movably installed on the top wall of the worktable 1. A rectangular frame is integrally formed between the two L-shaped fixing plates 3, and an angle sensor 13 is provided on the upper surface of the L-shaped fixing plates 3. A pressure plate 4 is movably installed on the top wall of the two L-shaped fixing plates 3, and a pressure sensor 10 is provided on the lower surface of the pressure plate 4. A collaborative control component 7 is provided on one side of the worktable 1. The collaborative control component 7 includes a PLC base plate 71, a control unit 72, a signal processing unit 73, and an interface unit 74 for controlling the pressure sensor 10, the angle sensor 13, and the drilling and milling head 5 to work collaboratively.

[0025] refer to Figure 4 One side of the workbench 1 is fixed to the PLC base plate 71 with bolts, and the control unit 72, signal processing unit 73, and interface unit 74 are welded to one side of the PLC base plate 71. It should be noted that the control unit 72 is based on a PLC (such as Siemens S7-1200) or an embedded chip (such as STM32H7 series), and is responsible for receiving sensor signals, performing logical operations (such as pressure / angle threshold judgment, parameter adjustment algorithm), and sending control commands to the drive equipment. The signal processing unit 73 interfaces with the pressure sensor 10 and the angle sensor 13, converting analog signals (such as voltage / current) into digital signals for easy recognition by the main controller; the signal cable connecting the pressure sensor 10 and the angle sensor 13 supports common signal types (such as 4-20mA, 0-10V, or digital pulse signals).

[0026] refer to Figure 3Servo motors 12 are fixed to the left and right inner walls of the worktable 1, and the output end of each servo motor 12 is fixed to one side of the L fixed plate 3 through a connecting shaft to drive the L fixed plate 3 to rotate. An electric telescopic rod 11 is fixed to the upper surface of the L fixed plate 3 by bolt brackets. The output end of the electric telescopic rod 11 passes through the L fixed plate 3 and is fixed to the upper surface of the pressure plate 4 by bolts. A pressure sensor 10 is embedded in the lower surface of the pressure plate 4.

[0027] It should be noted that the appropriate pressure detected by the pressure sensor 10 needs to be determined comprehensively based on the material, wall thickness, cross-sectional shape, and processing conditions of the aluminum profile. The typical range is 0.2MPa to 1.5MPa (approximately 2 to 15 kgf / cm²). Specifically, for thin-walled aluminum profiles (wall thickness ≤ 2mm) or easily deformable irregular cross-section profiles, the pressure needs to be controlled between 0.2 and 0.5MPa to avoid excessive pressure causing profile deformation and affecting processing accuracy. For thick-walled aluminum profiles (wall thickness ≥ 3mm) or solid profiles, the pressure can be increased to 0.8 to 1.5MPa to ensure stability and prevent displacement due to vibration during processing. For conventional rectangular and square profiles with medium wall thickness (2 to 3mm), the pressure is generally set between 0.5 and 0.8MPa, which satisfies clamping requirements while avoiding excessive compression.

[0028] refer to Figure 2 The top wall of the worktable 1 is fixed with an electric XY axis 8, and the output end of the electric XY axis 8 is fixed with an electric Z axis 9. The output end of the electric Z axis 9 is fixed with a drilling and milling head 5 through a mounting bracket to control the flexible movement of the drilling and milling head 5.

[0029] refer to Figure 2 The lower end of the workbench 1 is provided with a through groove, and a conical collection trough 14 is welded to the outer edge of the through groove. The cooling system 6 includes a water tank 61 fixed to one side of the workbench 1. A water pump 62 is installed in the water tank 61. An electric nozzle 63 is fixed to the output end of the water pump 62 through a corrugated pipe. The electric nozzle 63 is fixed to one side of the drill and milling head 5 by bolts. The input end of the water pump 62 is connected to the conical collection trough 14 through a hose. A filter screen is installed on the top of the conical collection trough 14 by bolts to filter residue.

[0030] The working principle of this utility model is as follows: During processing, the aluminum profile is placed on the rectangular frame between two L-fixed plates 3 and initially positioned by the two L-fixed plates 3. Then, the electric telescopic rod 11 is started, pushing the pressure plate 4 downward until the pressure plate 4 contacts the aluminum profile and applies pressure. At this time, the pressure sensor 10 on the lower surface of the pressure plate 4 will detect the contact pressure in real time and transmit the signal to the signal processing unit 73 in the cooperative control component 7. The signal processing unit 73 processes the signal and transmits it to the control unit 72. The control unit 72 controls the extension and retraction of the electric telescopic rod 11 through the interface unit 74 according to the preset pressure value to ensure that the pressure of the pressure plate 4 on the aluminum profile is uniform and meets the processing requirements.

[0031] When the aluminum profile needs to be processed at different angles, the servo motor 12 starts and drives the L fixed plate 3 to rotate through the connecting shaft. The angle sensor 13 on the upper surface of the L fixed plate 3 monitors the rotation angle in real time and sends the angle signal to the control unit 72 after processing by the signal processing unit 73. The control unit 72 controls the start and stop of the servo motor 12 according to the preset angle value to achieve precise control of the aluminum profile flipping angle. During the drilling and milling process, the electric XY axis 8 and the electric Z axis 9 work together to drive the drilling and milling head 5 to move flexibly in the X, Y and Z directions to complete the drilling and milling operation at different positions of the aluminum profile.

[0032] At the same time, the cooling system 6 starts to work. The water pump 62 in the water tank 61 draws the coolant collected in the conical collection tank 14 through the hose, and then delivers it to the electric nozzle 63 through the corrugated pipe. The electric nozzle 63 sprays coolant onto the processing parts of the drill and milling head 5 and the aluminum profile, which plays a role in cooling and lubrication. The used coolant flows into the conical collection tank 14 through the through groove at the bottom of the worktable 1, realizing the recycling of coolant.

[0033] Throughout the process, the PLC base plate 71 in the collaborative control unit 7 provides the foundation for the installation and electrical connection of each unit, and the control unit 72 coordinates the work of components such as the pressure sensor 10, angle sensor 13, and milling head 5 to ensure the orderly progress of the processing.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
