[0070] Working principle:

[0071] The profile is placed on the profile transmission device 10 and positioned by the feeding positioning plate 19. After positioning, the aluminum profile is transmitted by the profile transmission device 10 to the roller 45, so that the inner side of the aluminum profile contacts the blocking positioning wheel 8. The photoelectric switch senses the aluminum profile, and the roller 45 is lifted by the third lifting cylinder 40. At the same time, the clamping lifting cylinder 14 is lifted, and after lifting, the feeding clamping cylinder 16 is pushed forward to ensure that the bearing 17 contacts the outer side of the aluminum profile. At this time, the second lifting cylinder 57, the lifting cylinder 58, and the first lifting cylinder 26 are also in the lifting state.

[0072] The first servo motor 63 drives the feeding claw to return to the corresponding position of the first frame 5, and the first clamp 74 and the second clamp 75 on the feeding claw are in the open state under the push of the feeding cylinder 70. The first servo module 62 and the second servo module 67 move to the corresponding position according to the size of the aluminum profile. The 90° rotating device of the feeding claw ensures that all kinds of aluminum profiles can be grasped. After the feeding claw moves to the corresponding position, the clamping cylinder 59 works to make one side of the aluminum profile just positioned enter between the first clamp 74 and the second clamp 75. At the same time, the first clamp 74 and the second clamp 75 on the feeding claw are merged under the operation of the feeding cylinder 70 to ensure the clamping of the profile.

[0073] After being positioned on the feeding roller, the feeding claw clamps the profile and moves forward, and the second rotary cylinder 60, the second lifting cylinder 57, the lifting cylinder 58, and the clamping cylinder 59 retreat; the feeding claw continues to move close to the feeding clamping device, and the first rotary cylinder 32 and the first lifting cylinder 26 retreat synchronously. The first servo motor 63 works to make the aluminum profile enter the workbench adjustment plate 103. The first servo motor 63 delivers the aluminum profile to the corresponding position according to the command issued by the control system 4, and the upper clamping cylinder 106 clamps the aluminum profile. The horizontal clamping cylinder 104 on the workbench adjustment plate 103 clamps the aluminum profile horizontally, so that the aluminum profile contacts the positioning block 105. At this time, the sawing motor seat is pushed by the cylinder to move the sawing motor 114 fixed thereon outward to the corresponding position. The output end of the sawing motor 114 is installed with a saw blade. The sawing motor 114 cuts the aluminum profile flush under the action of the Z-axis motion cylinder.

[0074] After the head is aligned, the first end milling head starts to move along the Y axis to process the end face of the aluminum profile that has been aligned. After processing the end face, the first end milling head withdraws to the initial position. At this time, the mobile end clamping mechanism moves to the corresponding position along the X axis, the fixed end clamping mechanism is released, and the feeding air claw feeds according to the length of the profile to be processed. After the feeding is completed, the fixed end clamping mechanism and the mobile end clamping mechanism are clamped and positioned at the same time.

[0075] After the aluminum profile is positioned, the sawing motor seat is pushed by the cylinder to move the sawing motor 114 fixed thereon outward to the corresponding position, and a saw blade is installed at the output end of the sawing motor 114. The sawing motor 114 cuts the aluminum profile under the action of the Z-axis motion cylinder. After the cutting is completed, the moving end is pressed and moves along the guide rail. When the aluminum profile is being sawed, each roller is in an extended state to support the aluminum profile to be processed. After sawing, the moving end presses the workbench to the corresponding position. At this time, each material support telescopic device 128 is in a retracted state. After positioning, the first end milling head and the second end milling head on the first beam 79 and the second beam 80 perform end milling through the second servo motor 81. The first end milling head and the second end milling head are in a symmetrical relationship. Before the end milling operation, the first end milling motor 91 and the second end milling motor 100 are fixed on the end milling head at the same time. One or more end milling cutters are fixed on the first end milling motor 91. The second end milling motor 100 has an end milling cutter fixed at one end and a saw blade fixed at the other end. If a cutting operation is required, the second end milling motor switches the milling cutter and the saw blade by rotating the cylinder 99.

[0076] After the end milling is completed, the extraction claw moves to the corresponding position under the action of the X-axis motion motor 145, and the movable clamping part 153 and the fixed clamping part 154 on the extraction claw clamp the profile. If the position is not appropriate during the clamping process, the extraction claw can adjust the position of the fixed clamping part 154 through the limit block 151. The height of the extraction claw can be adjusted by the handle to adjust the screw. During the clamping process of the extraction claw, the lifting cylinder 137 is pushed out to make the extraction roller 141 flush with the clamping workbench 122. The extraction claw extracts the profile onto the extraction roller 141 under the action of the X-axis motion motor 145. Then the extraction roller 141 falls back under the action of the lifting cylinder 137, and after falling back, it is first lifted up by the first longitudinal conveyor belt mechanism 169 on the outgoing transmission platform 156, and then transmitted to the first transverse transmission roller 168.

Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
