In this invention, we are simply using them without modifying their structure or function. Their setting method, installation method, and electrical connection method can be easily understood by those skilled in the art by following the instructions for use, and will not be described in detail here.

[0035] In summary, the working principle of this multi-functional five-axis machining center is as follows: Before use, firstly, install the control circuit for the first servo motor 4, the second servo motor 5, the third servo motor 7, the milling spindle motor 9, the fourth servo motor 21, the fifth servo motor 26, the electric telescopic rod 28, the sixth servo motor 31, the first electromagnet 32, and the second electromagnet 33. Install the welding machine with the welding head 8 and connect the welding machine to the control circuit. Install the main control panel with the control circuit, which contains the main control system. Then, perform equipment debugging. After debugging, machining operations can begin. Connect the main power supply. The main control panel is then activated, and the system automatically enters self-test mode. It tests the speed, torque feedback, and braking functions of the first servo motor 4, second servo motor 5, third servo motor 7, fourth servo motor 21, fifth servo motor 26, and sixth servo motor 31. It also tests the lubrication and presence of jamming in the horizontal servo screw 13, vertical servo screw 14, vertical adjustment servo screw 16, and horizontal adjustment servo screw 17; the adsorption and release performance of the first electromagnet 32 ​​and second electromagnet 33; the clamping force and coaxiality of the tool chuck 10; and the closing status of the slag collection drawer 43, preparing for the quick-connect pipe 44 to collect slag. For hoses, test the sealing performance between the hose and the equipment. If any problems are found, address them accordingly. After resolving the issues, continue testing until the entire equipment has been tested and found to be problem-free, then it can be used. Based on the workpiece material, machining type (welding or milling), and precision requirements in the target part's machining drawings, preset parameters in the main control system. For example, for milling, set the milling spindle speed to 3000r / min-12000r / min, the feed rate to 50mm / min-500mm / min, and the depth of cut to 0.1mm-5mm per pass. Then, load the target part blank. The billet is clamped by bolts and a standard pressure plate through the T-slot 45 on the fixture table 6. Then, the flatness (error ≤ 0.02 mm) and coaxiality (radial runout of rotating parts ≤ 0.01 mm) of the billet surface are checked with a dial indicator to ensure clamping accuracy. Under the meshing transmission of the drive gear 35 and the rack 36, the first servo motor 4 is started. The first servo motor 4 is powered on and runs, which can realize the motion drive of the drive gear 35, and then drive the sliding frame 2 to slide along the dovetail track 39. After the adjustment is completed, the first servo motor 4 is braked, completing the auxiliary positioning of the sliding frame 2 on the central equipment table 1.

[0036] When the blank needs welding, the first servo motor 4 controls the sliding frame 2 to move backward relative to the central equipment table 1, so that the sliding frame 2 is close to the portal frame 11 and enters the working position of the welding head 8. The horizontal servo screw 13 on the portal frame 11 is activated, so that the welding head 8 is directly above the area of ​​the blank to be welded. Then the vertical servo screw 14 is activated, driving the welding head mounting seat 15 to adjust the height of the welding head 8 to a height that matches the blank. If the surface to be welded is an inclined or curved surface, the second servo motor 5 is activated. The second servo motor 5 drives the transfer frame 3 to rotate around the sliding frame 2 in steps within a range of ±90° through the coupling 38 on its rotating spindle. At the same time, the third servo motor 7 is activated. The third servo motor 7 drives the fixture table 6 through the coupling 38 on its rotating spindle. The welding head 8 rotates within a 360° range and is calibrated using a laser positioning device to ensure the surface to be welded is aligned with it, thus enabling welding operations. During milling operations, the vertical adjustment servo screw 16 adjusts the height of the milling spindle motor 9. The horizontal adjustment servo screw 17, driven by the transfer mount, moves the tool chuck 10 along the Z-axis to raise it, bringing it closer to the disc-shaped frame 20 until it enters the tool changing area. Then, the horizontal adjustment servo screw 17 is activated, driving the motor base 18 to move laterally, allowing the tool chuck 10 to enter the tool changing area horizontally. Each tool slot 24 on the disc-shaped frame 20 corresponds to a different tool, such as a No. 1 face milling cutter or a No. 5 end mill. The tool number is input into the central control system, and the central control system calculates the tool's position. The rotation angle of the disc frame 20 is adjusted by the operation of the fourth servo motor 21, which enables the drive gear 35 on its main shaft to rotate. Under the meshing transmission of the drive gear 35 and the spur ring 37, starting the fourth servo motor 21 drives the disc frame 20 to rotate around the bottom of the cross frame 19. After the target tool slot 24 reaches directly below the tool chuck 10 to be replaced, automatic tool changing is performed. The operation of the fifth servo motor 26 drives the rotary mounting frame 25 to rotate around the cross frame 19 through the coupling 38 connected to its main shaft, so that the tool holder 30 on the flipping frame 29 is aligned with the tool to be retrieved. The electric telescopic rod 28 is activated to push the sliding extension frame 27 closer to the tool shank of the target tool. When the tool shank is inserted into the tool holder 30 by 20mm-30mm, the first... Electromagnet 32 ​​and second electromagnet 33 form a fixed tool. A silicone rubber buffer cap 34 mitigates impact when in contact with the tool shank. Then, the electric telescopic rod 28 pulls the sliding extension frame 27 in the opposite direction, allowing the target tool to be extracted relative to the tool storage slot. Next, the sixth servo motor 31 drives the tilting frame 29 to rotate 180°, aligning the tool shank with the tool chuck 10. The electric telescopic rod 28 then pushes the sliding extension frame 27 to move, feeding the tool into the tool chuck 10. The tool chuck 10 senses the tool insertion and automatically clamps it in place. After confirmation by the central control system, the first electromagnet 32 ​​and second electromagnet 33 are de-energized. Then, the electric telescopic rod 28 drives the sliding extension frame 27 to retract, and the fifth servo motor 26 drives the rotary mounting frame 25 back to its initial position.To avoid affecting subsequent milling operations, the initial position is the foremost position where the sliding extension frame 27 can rotate. Then, the first servo motor 4 controls the sliding frame 2 to move forward relative to the central equipment table 1, bringing it closer to the vertical mounting frame 12 until it enters the working position between the two milling spindle motors 9. Afterward, the milling spindle motors 9 start, driving the tool movement. Once the tool's rotation is stable, the vertical adjustment servo screw 16 and the horizontal adjustment servo screw 17 work together to achieve spatial movement of the tool, realizing the workpiece machining operation. During machining, depending on the specific shape of the target part, machining can be achieved by running one milling spindle motor 9 or by running two milling spindle motors 9 simultaneously to improve work efficiency.

[0037] During the processing, the first servo motor 4 drives the sliding frame 2 to adjust its position relative to the central equipment table 1, thereby moving and feeding the billet. The second servo motor 5 drives the intermediate frame 3 to swing and adjust, thereby adjusting the tilt posture of the billet. The third servo motor 7 is powered on to rotate the fixture table 6, thereby adjusting the self-rotation of the billet, enriching the posture of the billet during welding and cutting, and thus enriching the processing surface of the billet. In terms of waste collection, milling metal chips and welding slag fall naturally into the slag collection drawer 43 through the collection port 41 at the top of the sliding frame 2. The quick-connect pipe 44 on the slag collection drawer 43 is connected to the workshop negative pressure system. Turning on the negative pressure pump with a negative pressure value of -0.05 to -0.08 MPa can accelerate the collection. To further improve the intelligence and safety of the slag collection process, a detection sensor can be installed in the slag collection drawer 43. When the waste reaches 80% of the volume, the screen of the main control panel will display a "drawer full" prompt. The slag collection drawer 43 with a self-locking structure can be pulled out during the processing interval and cleaned. After locking and retracting, for welding, the arc of the welding head 8 must be shut off first, and the protective gas should be maintained for a 5-10 second delay before shutting off to prevent weld oxidation. For milling, the speed of the milling spindle motor 9 should be reduced to below 1000 r / min before stopping the rotation of the spindle to prevent unnecessary tool wear. When removing the workpiece formed from the blank, the first servo motor 4 should be used to move the sliding frame 2 into the space between the gantry frame 11 and the vertical mounting frame 12 for the operator to retrieve. When unloading the workpiece, wear high-temperature resistant gloves. Loosen the bolts on the fixture table 6 with a wrench according to the "diagonal loosening" principle. Finally, slowly remove the workpiece. To facilitate the establishment of coordinate axes in the overall control system, we take the movement of the sliding frame 2 as the X-axis (equipment length direction), the lateral movement of the welding head 8 and the lateral movement of the milling spindle motor 9 as the Y-axis (equipment width direction), the vertical movement of the welding head 8 or the vertical movement of the milling spindle motor 9 as the Z-axis (vertical direction), the rotation of the transfer frame 3 as the A-axis, and the rotation of the fixture table 6 as the C-axis.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
