[0046] Embodiment 2

[0047] Based on the above-mentioned embodiment 1, during the process of clamping the door frame by the fixing plate 531, since the door frame body has flexibility, the center position of the door frame will bend during the clamping process by the fixing plate 531 and the rubber pad 532, and the curvature of the door frame cannot be corrected only by the supporting force of the fixing plate 531, resulting in deviations in the cutting accuracy during the cutting process of the door frame, affecting the normal use of the door frame.

[0048] like Figure 9-11 As shown, two movable grooves 5311 are provided on the opposite sides of the fixing plate 531, and the movable groove 5311 runs through one side of the width of the fixing plate 531, and an adjusting rod 5312 is slidably arranged in the movable groove 5311, wherein the end of the adjusting rod 5312 close to the movable groove 5311 is connected with a connecting seat, and the base can move along the movable groove 5311, and at the same time, the length of the adjusting rod 5312 can be telescopically controlled, and the adjusting rod 5312 can rotate relative to the movable groove 5311, that is, the adjusting rod 5312 can be mutually engaged with the movable groove 5311, and the adjusting rod 5312 is away from the fixing plate 5311. One end of the sheet 531 is rotatably connected to the bearing plate 5321, that is, the two ends of the adjusting rod 5312 are respectively hinged to the bearing plate 5321 and the connecting seat, and the end of the bearing plate 5321 away from the adjusting rod 5312 is connected to a plurality of detection springs 5322 for identifying the pressure between the rubber pad 532 and the door frame. The plurality of detection springs 5322 are all connected to the rubber pad 532. When the rubber pad 532 contacts and squeezes the door frame, the rubber pad 532 compresses the detection spring 5322, and at this time, the pressure exerted on the detection spring 5322 is the same as the contact pressure between the rubber pad 532 and the door frame.

[0049] It should also be noted that one end of the detection spring 5322 is connected to the rubber pad 532, and the rubber pad 532 will bend and deform, so that the pressure value borne by each detection spring 5322 can be displayed separately, thereby facilitating the identification of the connection status of the door frame.

[0050] A gasket 5313 is connected to one end of the fixing plate 531 close to the supporting plate 5321, thereby ensuring that the fixing plate 531 will not cause damage to the door frame body when compensating for the connection area of ​​the rubber pad 532. In order to ensure that when the gasket 5313 conflicts with the door frame, the fixing plate 531 can slide relative to the gasket 5313, in this embodiment, the connecting rod 530 is set as a rod of a telescopic structure.

[0051] After the position of the door frame is constrained by the fixing plate 531 and the rubber pad 532, the connection status of the door frame on the fixing plate 531 is identified according to the pressure value on the detection spring 5322. When the door frame is in the process of being connected, the pressure values ​​borne by the detection springs 5322 at various positions are the same or have little difference. This means that the connection of the door frame is stable, and the cutting accuracy of the door frame can be ensured during the cutting process.

[0052] When the force on the detection springs 5322 close to each other on the two groups of rubber pads 532 connecting the door cover is significantly greater than the pressure value of the detection springs 5322 in other areas, it means that the center position of the door cover has a large bending, thereby controlling the adjustment rod 5312 to move along the moving groove 5311, and at the same time controlling the length of the connecting rod 530 to extend, causing the fixing plate 531 and the rubber pad 532 to be misaligned, and when the adjustment rod 5312 moves to the middle area of ​​the moving groove 5311, the angle of the control adjustment rod 5312 is deflected and the length is adjusted. The extension is adjusted while ensuring that the contact pressure between the rubber pad 532 and the door frame does not change, until the adjusting rod 5312 is completely received in the movable groove 5311, and at this time the fixing plate 531 and the rubber pad 532 are at the same level, and the gasket 5313 and the rubber pad 532 are used to constrain the position of the door frame, thereby increasing the restraining force of the door frame, and expanding the contact range of the rubber pad 532 through the fixing plate 531, increasing the supporting range of the door frame, achieving a reduction in the bending angle of the middle part of the door frame, and improving the accuracy of the door frame during cutting.

[0053] In addition to using the detection spring 5322 to identify the degree of bending of the door frame, the detection spring 5322 can also be used to determine the fixed position of the door frame. That is, when relative displacement occurs between the door frame and the rubber pad 532, the connection condition of the door frame can be determined through the elastic change area of ​​the detection spring 5322, thereby ensuring that the door frame will not be separated from the rubber pad 532 due to interference from external forces during the connection process, thereby improving safety of use.

[0054] Embodiment 3

[0055] A door panel positioning and clamping method, using the door panel positioning and clamping assembly as described above, comprises the following steps:

[0056] Step 1: After placing the plate to be cut on the movable table 4, use the positioning and clamping module 5 to fix and clamp the plate (start the rotating motor 504, the rotating motor 504 drives the bidirectional screw rod 503 to rotate, so that the two bracket plates 506 move on the rectangular groove 501, so that the plate to be cut can be placed between the bracket plates 506, start the hydraulic rod 507, the hydraulic rod 507 drives the slider 509 to descend, so that the plate is located between the two connecting plates 525, and the toothed locking rod 535 is opened. The toothed locking rod 535 releases the lock of the adjustment frame 520 connected to the single-bevel gear ring 533, so that the adjustment frame 520 is twisted under the torsion of the coil spring 523. The circular shaft 529 in the surface groove 521 drives the moving block 527 to move outward on the rectangular opening 526, so that the two fixing plates 531 are fully unfolded. After the plate is placed between the two fixing plates 531, the lever 524 is held and rotated, so that the circular shaft 529 drives the moving block 527 to move toward the center of the connecting plate 525. At the same time, the rotating single-bevel gear ring 533 will use the bevel teeth to push the toothed locking rod 535 under the torque limit of the torsion spring 537. After the fixing plate 531 connected to the connecting rod 530 clamps the plate and ensures that the rubber pad 532 is in contact with the surface of the plate, the hydraulic rod 507 is started again to make the slider 509 lift the plate and start cutting);

[0057] Step 2: When the cutting position on the plate needs to be adjusted, use the cutting point adjustment module 6 to translate the plate from the central position on the base frame 1 to both sides, thereby changing the cutting position (when the cutting position on the plate needs to be adjusted, push the locking ring 608 in the direction of the threaded rod 604, so that the locking ring 608 overcomes the thrust of the connecting spring 611 and moves on the limit block 609, so that the rack 610 releases the lock on the outer gear ring 607, turn the knob 612 and drive the threaded rod 604 to rotate, so that the threaded rod 604 drives the movable part 602 connected to the long rod 605 to overcome the thrust of the protection spring 603 and slide on the slide rod 601, and adjust the distance required to move through the scale displayed on the scale 606, so that the base plate 2 connected to the movable part 602 can drive the plate on the movable platform 4 to translate to one side, so that the device can adjust the cutting position on the plate).

[0058] Step 3, start cutting. When cutting is required on both the front and back sides of the plate, use the positioning clamping module 5 to turn the plate over (if the bottom surface of the plate needs to be cut, grab and pull the rotating member 512 to make the rotating member 512 slide on the limit bar 511, so that the pin 514 connected to the rotating member 512 is pulled out from the insertion hole 513, and the rotating member 512 is rotated one hundred and eighty degrees. At this time, the position of the pin 514 and the insertion hole 513 are twice corresponded, and driven by the limit bar 511, the shaft 510 will drive the plate on the fixed plate 518 to rotate. After the rotation is completed, release the rotating member 512, and under the pull of the reset spring 517, the pin 514 will be reinserted into the insertion hole 513).
