Technical Field

[0001] The invention relates to the technical field of mechanical processing, in particular to a moving column type CNC gantry milling machine. Background Art

[0002] Milling machines mainly refer to machine tools that use milling cutters to process various surfaces of workpieces. Usually, the rotation of the milling cutter is the main motion, and the movement of the workpiece and the milling cutter is the feed motion. It can process planes, grooves, various curved surfaces, gears, etc. Milling machines are machine tools that use milling cutters to mill workpieces. In addition to milling planes, grooves, gear teeth, threads and spline shafts, milling machines can also process more complex surfaces. They are more efficient than planers and are widely used in mechanical manufacturing and repair departments. Milling machines can process planes (horizontal planes, vertical planes), grooves (keyways, T-slots, dovetail grooves, etc.), toothed parts (gears, spline shafts, sprockets), spiral surfaces (threads, spiral grooves) and various curved surfaces. In addition, it can also be used for machining the surface of a rotating body, inner holes, and cutting work. When the milling machine is working, the workpiece is mounted on a workbench or an accessory such as a dividing head. The rotation of the milling cutter is the main motion, supplemented by the feed motion of the workbench or milling head, and the workpiece can obtain the required machining surface. Because of the multi-edge interrupted cutting, the productivity of the milling machine is higher. Simply put, a milling machine is a machine tool that can perform milling, drilling and boring on the workpiece.

The arrangement of the cone end top and the pressure sensor facilitates the device to charge points on the workpiece surface through the cone end at the bottom of the cone end top and cooperates with the pressure sensor, and can also locate the drilling position of the workpiece without the drill bit touching the workpiece surface.

[0032] The working steps of this scheme are summarized and sorted out according to the above technical scheme: when in use, the forklift can be used to support multiple groups of plates between multiple layers of horizontally opposite triangular plates 203, and then the dual-axis motor 204 can be started to drive the conveyor belt 202 to drive the plates placed on the upper surface of the triangular plate 203 to rise to a specific height, and then the electric push rod 502 can be started, and the electric push rod 502 pushes the scissor-type telescopic frame 501 to extend from the lower end of the plate to the other end, and then the dual-axis motor 204 can drive the triangular plate 203 on the outer surface of the conveyor belt 202 to drive the plates placed on the upper surface to descend back to their original position, so that the triangular plate 203 can drive the top plate to press against the surface of the extended scissor-type telescopic frame 501 to support it, and then the electric push rod 502 can be started again.

[0034] It is worth noting that the moving column CNC gantry milling machine in this embodiment is also equipped with an industrial-grade PLC controller (such as Siemens S7-1500 series) as the main control unit, and is also equipped with a 10-inch industrial touch screen that communicates with the PLC controller in real time to provide a human-machine interface. The main control unit is respectively connected to the first motor 106, the dual-axis motor 204, the second motor 302, the third motor 305, the first linear module 309, the electric push rod 502, the second linear module 401, and the blower 102 with electric wires, and is used to control the first motor 106, the dual-axis motor 204, the second motor 302, the third motor 305, the first linear module 309, the electric push rod 502, the second linear module 401, and the blower 102 to automatically operate, so as to improve the working efficiency of the moving column CNC gantry milling machine.

[0035] In addition, this embodiment also provides a loading detection sensor, a positioning detection sensor, a plate height detection sensor, a processing area safety sensor, and a unloading completion detection sensor, wherein: The feeding detection sensor is a photoelectric sensor (the transmitting end and the receiving end are installed in pairs) and is provided with multiple groups, which are respectively installed on both sides of the feeding end of the bottom triangle plate 203 of the supporting mechanism 2 and the side wall of the base 1 at the entrance of the U-shaped casing 101, and are used to detect whether the plate fed by the forklift has completely entered the supporting area, and are used to trigger the start of the dual-axis motor 204 to control the conveyor belt 202 to start the lifting action to prevent the stacking of multiple plates from exceeding the limit (by installing multiple groups of sensors in layers); The positioning detection sensor is a reflective photoelectric sensor (with background suppression function), which is installed on the inner end surface of the positioning plate 105 (flush with the contact surface of the sheet) and the end of the extension path of the scissor-type telescopic frame 501 of the unloading and clamping mechanism 5, and is used to confirm whether the front end of the sheet is completely in contact with the positioning plate 105, detect whether the unloading and clamping mechanism 5 is extended in place, and feedback signals to the PLC controller to allow the start of three-axis processing (positioning + clamping double confirmation is required); The plate height detection sensor is a diffuse reflection photoelectric array (multiple groups are installed), which is installed on the inner wall of the base 1, evenly distributed in the vertical direction (the spacing matches the standard thickness of the plate), and installed above the moving path of the pressure contact wheel 503 of the unloading clamping mechanism 5, and is used to detect the actual height of the plate after the supporting mechanism 2 is lifted, determine which layer of the plate is currently being processed (for continuous processing counting), and prevent the unloading clamping mechanism 5 from interfering with the plate that has not been lifted; The processing area safety sensor is a safety light curtain (covering the processing area horizontally), which is installed 200mm below the milling cutter of the first motor 106 of the three-axis linkage mechanism 3 and on both sides of the lifting path of the U-shaped receiving tray 402 of the receiving mechanism 4, and is used to monitor in real time whether there is foreign matter intrusion in the processing area, trigger emergency stop protection (response time <50ms), and prevent the unloading action from being mistakenly started when the receiving mechanism 4 is not fully unfolded; The unloading completion detection sensor is a slot-type photoelectric sensor (U-shaped structure), which is respectively installed at the entrance edge of the storage hopper 404 of the material receiving mechanism 4 and the end of the inclined section of the U-shaped receiving tray 402. It is used to confirm that the processed plate has completely slid into the storage hopper 404, detect whether the debris collection amount reaches the preset threshold (determined by periodic occlusion), and trigger the reset signal of the material receiving mechanism 4 to prepare for the next cycle.

[0036] When continuous processing is performed, the sensor signal linkage process is as follows: The feeding sensor detects a new plate → the dual-axis motor 204 starts to lift; The height sensor confirms that the set layer has been reached → the unloading clamping mechanism 5 extends; The positioning sensor feedbacks the plate clamping → the three-axis linkage mechanism 3 starts processing; Safety light curtain continuously monitors → abnormal blocking immediately stops the spindle; The unloading sensor triggers the completion signal → the receiving mechanism 4 resets and clears the count; The overall control process is as follows: A[System initialization]-->B[Automatic feeding detection] B-->C{plate position?} C--Yes-->D[Lifting mechanism] D-->E[unloading clamp extended] E-->F[Plate clamping confirmation] F-->G[Processing area closed] G-->H[Three-axis machining] H-->I[Synchronous cleaning of debris] I-->J{Processing completed?} J--Yes-->K[Prepare for unloading] K-->L[Expand the material receiving mechanism] L-->M[Automatic unloading] M-->N{Continue processing?} N--Yes-->B N--No-->O[System Standby].

[0040] Control action: Automatically adjust the spindle speed to:

[0041] 2. Calculate the air volume of the air knife: Qair=1.2×0.05×3600+300 / 1.2=216+250=466m 3 / h

[0042] Control action: adjust the blower inverter to the corresponding air volume gear; The solution has the following technical effects: 1. Dynamic cutting optimization: The cutting speed is automatically adapted to the material removal rate and tool load in real time, significantly improving the machining efficiency. Tool life is significantly extended (by avoiding overloading under constant parameters); 2. Cleaning collaborative control: The air volume supply and the amount of debris generated are precisely matched, and the amount of debris residue is greatly reduced; Significantly lower energy consumption (compared to fixed air volume mode); 3. Security enhancements: When δ(h)>2.0, the thickness abnormality alarm is automatically triggered (indicating that the plate positioning is offset) pass Monitoring to achieve early warning of spark splashing; Dynamic control mechanism Cutting speed control: When the cutting force F is detected t When it increases (such as encountering a hard spot in the material), the denominator of the equation increases and v is automatically reduced c , to prevent tool overload; When the plate thickness decreases, δ(h) increases, and the speed is increased compensatorily to maintain a stable cutting rate; Air volume coordination mechanism: The term γ·(dm / dt) ensures the basic debris removal capability; The kinetic energy of chips increases during high-speed cutting, and additional air volume is required to prevent splashing; Thickness abnormality warning: When the δ(h) function value suddenly exceeds the threshold, it is judged as a plate displacement or interlayer adhesion failure; Trigger the emergency lift and release mechanism and suspend processing.

[0043] The cutting mechanics, fluid dynamics and real-time control theory are integrated to establish a machining-cleaning joint control model. δ(h) uses a hyperbolic tangent function to achieve a smooth transition of thickness influence and avoid the control oscillation of the traditional piecewise function. Incorporating chip kinetic energy into air volume calculations can help overcome the problem of spatter control during high-speed machining.
