Aluminium-material machining four-axis numerically-controlled milling machine

[0010] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. The exemplary embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0011] Such as Figure 1-2 As shown, a four-axis CNC milling machine for aluminum machining includes a CNC system 1, a moving mechanism, an A-axis servo drive mechanism 6, a rotating clamping platform 7, an automatic lifting protective door 8, a double-row in-line tool magazine 9, and a belt row The chip machine 10, the pneumatic clamp 11, the pneumatic positioning plate 12, the frame 13, and the guide rail 14. The numerical control system 1 is used to control the operation of the numerical control milling machine. The numerical control system 1 is connected to one side of the frame 13, and the frame 13 A double-row in-line tool magazine 9 is installed on the double-row in-line tool magazine 9 with an A-axis servo drive mechanism 6 and a pneumatic positioning plate 12 on one side. The pneumatic positioning plate 12 is provided with several rotary clamping platforms 7, A-axis The servo drive mechanism 6 is used to drive the rotary clamping platform 7 to execute real-time rotation instructions for the material according to the processing program. The rotary clamping platform 7 is equipped with a pneumatic clamp 11, and the front of the rotary clamping platform 7 is equipped with an automatic lifting protective door 8. A belt chip conveyor 10 is provided at the bottom of the frame 13, and the moving mechanism includes an automatic tool-changing electric spindle 2, an X-axis servo transmission mechanism 3, a Y-axis servo transmission mechanism 4, and a Z-axis servo transmission mechanism 5. The moving mechanism is installed On the guide rail 14 of the rack 13.

[0012] The working principle of the present invention:

[0013] A1: Call the edited machining program in CNC system 1, use the system's handwheel to set the tool, and set the workpiece coordinates;

[0014] A2: Then implement (action 2) put the aluminum profile to be processed into the rotating clamping platform 7 and align the position of the XYZ positioning plate; press the start button of the CNC system, the pneumatic clamp 11 will return the aluminum profile clamp pneumatic positioning plate 12;

[0015] A3: Followed by (action 3 raises the automatic lifting protective door;

[0016] A4: Then implement (action 4) the automatic tool change electric spindle 2 starts the numerical control system 1 to start the processing program;

[0017] A5: Then implement (action 5) X-axis servo drive mechanism 3, Y-axis servo drive mechanism 4, Z-axis servo drive mechanism 5 drive the automatic tool change electric spindle 2 to execute the machining program position command, and the A-axis servo drive mechanism 6 drives the rotating device The clamping platform 7 executes the real-time rotation command of the material according to the processing program; realizes the purpose of four-axis processing of the front and multiple sides of the aluminum profile.

[0018] A6: Followed by (action 6) the processing program requires automatic tool change, X-axis servo drive mechanism 3, Y-axis servo drive mechanism 4, Z-axis servo drive mechanism 5 drive the automatic tool change electric spindle 2 to execute the automatic tool change command; automatic The tool-changing electric spindle 2 places the tool in the double-row in-line tool magazine 9 according to the steps of the system macro program setting, and takes out the corresponding tool in the double-row in-line tool magazine 9 according to the tool change instruction.

[0019] A7: Next (action 7) the processing program is executed, the automatic lifting protective door 8 is lowered, and the belt chip conveyor 10 starts to discharge the processed aluminum chips.

[0020] A8: Then implement (action 8) the pneumatic clamp 11 is loosened and the pneumatic positioning plate 12 is pushed out; the processing is completed, and the aluminum material is taken out.

[0021] A10: Cycle A2-A8 until the raw materials are processed.

[0022] The above technical solutions of the present invention are not limited to the limitations of the foregoing specific embodiments, and all technical modifications made according to the technical solutions of the present invention fall within the protection scope of the present invention.
