In addition, since the existing processing device mostly fixes the processing template by combining the processing template with the fixing plate through the holes opened on the processing table, the processing template is relatively clamped and fixed, which makes the template prone to falling off during processing, and it is not easy to fix the processing template when the shape of the processing template is more complicated. At the same time, since the door inner guard plate contains multiple parts, the processing device needs to use different processing molds to weld the parts. However, since the existing processing device needs to remove all nuts and bolts before replacing them when disassembling the welding joint, this step is too cumbersome and affects the processing progress.

[0020] 1. A door inner guard plate processing device for automobile interior, by holding a handle and pressing it downward, the rotating rod starts to rotate under the drive of the handle with the fixed long plates on both sides as support and its own central axis as the rotation axis, driving the abutment plate to be pushed toward the bottom template, and the rolling wheel in contact with it is also pushed to move toward the inside of the through groove, so that the rolling wheel drives the push rod to push inward and also affects the lifting rod. After the lifting rod receives the thrust from the pushing rod, the point where the lifting rod is hinged with the connecting block is used as the rotation axis.

At this time, the pressing rod is sleeved on the fixing bolt and clamped into the inside of a suitable limiting groove, and then the pressing nut is tightened. The surface of the fixing bolt is screwed in until it contacts the upper surface of the lower pressure rod. Since the bottom end of the fixing bolt is fixed by the limit plate and the fixed slide groove, the lower pressure nut will drive the lower pressure rod to slide downward while continuing to be screwed downward. Since the lower pressure rod is clamped in the inner part of the limit groove, the lower pressure rod will exert a downward pressure on the limit frame when moving downward. The tighter the lower pressure nut is screwed, the greater the downward pressure of the lower pressure rod on the limit frame, and the limit frame has a better fixing effect on the demoulding mechanism.

[0039] A method for processing a door inner panel processing device for automobile interior, comprising the following steps:

[0040] S1: First, the demoulding mechanism 6 is placed on the upper surface of the processing table 103, and then the limiting plate 501 is inserted into the fixed slide groove 104, and the limiting frame 503 is sleeved on the fixing bolt 502, so that the top of the limiting frame 503 is placed on the upper surface of the demoulding mechanism 6, and the pressing nut 507 is screwed to drive the pressing rod 506 to move downward to press the limiting frame 503 downward, and the demoulding mechanism 6 is fixed by pressing downward to complete the installation of the demoulding mechanism 6;

[0042] S3: Finally, hold the handle 606 and press it downward to make the support plate 607 push the push rod 612 and the lifting rod 611 to move the stripping plate 609 upward to eject the welded blank.

[0043] Working principle, when a door inner panel processing device for automobile interior is used, in the initial state, the inspection door 101 opened on the front of the processing device body 1 is convenient for repairing the interior of the processing device body 1, and the moving pulley 102 arranged at the bottom of the processing device body 1 is convenient for moving the entire device, and because the processing device body 1 has a braking effect, the processing device body 1 can effectively prevent the device from being displaced during operation, and the fixed slide groove 104 arranged on the processing table 103 is convenient for providing support for the limit plate 501 and the fixing bolt 502, so that the pressing nut 507 can drive the limit frame 503 to press down when moving downward to fix the demolding mechanism 6, and the control panel 105 arranged on the front of the processing device body 1 plays a role in controlling the operation of the entire device, and at the same time in the processing device body 1. The lifting device body 3 arranged above is connected to the column 2 by the limited lifting groove 301, and the lifting drive device extending to the inside of the lifting device body 3 is meshed with the lifting gear 202, which is convenient for automatically controlling the lifting of the lifting device body 3. The adjusting wheel 302 can manually adjust the position of the lifting device body 3 when the whole equipment is powered off. The fixing bolts 404 that are rotatably connected in the four rotating grooves 403 opened around the top compass 401 are clamped into the limited arc groove 407 and fixed by the fixing nuts 405. The shape of the arc groove 407 and the rotating groove 403 is set so that when the processing head mounting bottom compass 402 needs to be replaced or removed, it only needs to loosen the fixing nut 405 to make it rotatable to complete the disassembly, which is more convenient for replacing the welding joint. The stripping plate 609 sliding in the model groove 602 opened on the upper surface of the bottom template 601 is hinged with the lifting rod 611 through the linkage block 610, and the lifting rod 611 is connected with the pushing rod 612 to achieve linkage, so that when the rotating rod 605 rotates, the push plate 607 can push the pushing rod 612 and the lifting rod 611 to move and push the stripping plate 609 upward to eject the welded blank;

[0044] When the welded blank needs to be taken out, first hold the handle 606 and press it downward, so that the rotating rod 605 starts to rotate under the drive of the handle 606 with the fixed long plates 604 on both sides as the support and its own central axis as the rotation axis, driving the abutment plate 607 to push toward the bottom template 601, and the rolling wheel 613 in contact with it also moves toward the inside of the through groove 608 due to the push, so that the rolling wheel 613 drives the pushing rod 612 to push inward and also affects the lifting rod 611. After the lifting rod 611 receives the thrust from the pushing rod 612, it uses the point hinged with the connecting block 610 as the rotation axis and gradually maintains a vertical state with the pushing rod 612 with the assistance of the arc edge of the through groove 608, thereby pushing the connecting block 610 and the stripping plate 609 upward to eject the welded blank out of the mold groove 602. This device is convenient for taking out the welded blank.

[0045] When a new demoulding mechanism 6 needs to be installed, the demoulding mechanism 6 is first placed on the upper surface of the processing table 103, and then the limit plate 501 is inserted from the notch of the fixed slide groove 104 on both sides of the processing table 103 and moved to both sides of the demoulding mechanism 6. At this time, the limit frame 503 is sleeved on the surface of the fixing bolt 502 through the long groove 504, and the limit frame 503 is in contact with the top surface of the demoulding mechanism 6 on one side facing the demoulding mechanism 6, and the other side of the limit frame 503 is in contact with the upper surface of the processing table 103. At this time, the lower pressure rod 506 is sleeved on the fixing bolt 502 and clamped into the inside of the appropriate limit groove 505, and then the lower pressure nut 507 is screwed into the fixing bolt The surface of the fixed bolt 502 contacts the upper surface of the lower pressure rod 506. Since the bottom end of the fixed bolt 502 is fixed by the limit plate 501 and the fixed slide groove 104, the lower pressure nut 507 will drive the lower pressure rod 506 to slide downward while continuing to be screwed downward. Since the lower pressure rod 506 is clamped in the inner part of the limit groove 505, the lower pressure rod 506 will exert a downward pressure on the limit frame 503 when moving downward. The tighter the lower pressure nut 507 is screwed, the greater the downward pressure of the lower pressure rod 506 on the limit frame 503, and the limit frame 503 has a better fixing effect on the demoulding mechanism 6. The device is convenient for installing a new demoulding mechanism 6.

[0046] When it is necessary to replace the processing head mounting base compass 402, first loosen the fixing nut 405 so that the fixing bolt 404 can slide inside the limiting arc groove 407, then hold the bottom of the processing head mounting base compass 402 and rotate it counterclockwise until the fixing bolt 404 moves to the notch of the limiting arc groove 407 and the insert block 406 moves to the point where it can be removed from the slot 408, then pinch the bottom end of the fixing bolt 404 and push it outward to separate the fixing bolt 404 and the fixing nut 405 from the restriction of the limiting arc groove 407, then move the processing head mounting base compass 402 vertically downward to completely separate the insert block 406 from the slot 408 to complete the disassembly of the processing head mounting base compass 402, if it is necessary to install a new processing head mounting base compass 402, only need to reverse the above steps, this device is convenient for replacing the processing head mounting base compass 402.
