A group of sliding rods 518 are installed on the other end of the compression spring 517, and each group of the sliding rods 518 is slidably connected in the sleeve tube 516. A group of pressure sensors 519 are installed at the junction of each group of the sliding rods 518 and the third compression spring 517. A group of pressure-resistant plates 520 are installed on the top of each group of the sliding rods 518. A group of sleeve rings 521 are sleeved on the outer wall of each group of the sliding rods 518. A group of first distance sensors 522 are installed on the outer wall of each group of the sleeve rings 521, and a group of second distance sensors 523 are installed on the corresponding side walls of the two groups of the sleeve rings 521.

[0032] Before the door and window cutting device works, the first electric push rod 103 is first started to drive the second fixed plate 104 to move to the specified position, and then the clamping plate 405 is pushed to slide in the slide groove 402 toward the fixed block 403. The clamping plate 405 squeezes the first compression spring 404 during the sliding process, and the third electric push rod 506 is started during the sliding process to push the first electromagnetic block 507 and the second electromagnetic block 508 to be magnetically connected, and then the contact plate 504 is driven to move toward the fifth fixed plate 501. During the movement, the sliding tube 503 is driven to slide in the sleeve 502. And the contact plate 504 begins to squeeze the second compression spring 505, and then the doors and windows that need to be cut are placed on the two groups of contact plates 504, and then the magnetic connection between the first electromagnetic block 507 and the second electromagnetic block 508 is separated, and the second compression spring 505 begins to rebound after sensing the disappearance of pressure, driving the contact plate 504 to squeeze the doors and windows, and then separates from the push on the clamping plate 405. After the first compression spring 404 senses the disappearance of pressure, it drives the clamping plate 405 to elastically limit the doors and windows, so that the clamping has a buffering effect, which improves the wrapping limiting effect while improving the convenience of disassembly and assembly.

[0033] Before cutting, the fourth electric push rod 514 is started to push the two groups of anti-pressure plates 520 to move to the bottom of the cutting structure 205 and avoid the output end range of the cutting structure, and when it is for irregular doors and windows, the fifth motor 510 is started to drive the transmission plate 511 to rotate. While the transmission plate 511 rotates, it drives the two groups of anti-pressure plates 520 to always be parallel and in contact with the bottom of the doors and windows. Then, during the translation movement of the cutting structure 205, the fourth electric push rod 512 is started to drive the anti-pressure plates 520 to move synchronously. When the cutting structure 205 cuts the anti-pressure plates due to offset, the anti-pressure plates The pressure plate 520 will begin to squeeze the sliding rod 518 due to the pressure it senses. The sliding rod 518 will begin to squeeze the third compression spring 517 in the sleeve 516 during the buffering process. When the third compression spring 517 senses the pressure, it will exert a rebound force on the pressure sensor 519 to collect the numerical values ​​for warning. In addition, when the pressure-resistant plate 520 is squeezed, the two sets of sensors cannot be located at the same height distance, which improves the multi-layer warning function of the structure, avoids secondary damage to the door and window cutting, improves the precision of the door and window cutting, and improves the working effect of the device.

[0034] When the cutting structure 205 is offset and cuts the pressure-resistant plate, the pressure-resistant plate 520 will begin to squeeze the sliding rod 518 due to the pressure it senses, and the sliding rod 518 will begin to squeeze the third compression spring 517 in the sleeve 516 during the buffering process. When the third compression spring 517 senses the pressure, it will exert a rebound force on the pressure sensor 519, collect the values ​​for warning, and the pressure-resistant plate 520 will cause the two sets of sensors to be unable to be located at the same height distance during the squeezing process, thereby improving the multi-layer warning function of the structure, avoiding secondary damage to the doors and windows, and improving the precision of the doors and windows cutting while improving the working effect of the device.

[0035] The sliding tube 503 is driven to slide in the sleeve 502, and the contact plate 504 begins to squeeze the second compression spring 505. Then, the doors and windows that need to be cut are placed on the two groups of contact plates 504, and then the magnetic connection between the first electromagnetic block 507 and the second electromagnetic block 508 is separated. After the second compression spring 505 senses the disappearance of pressure, it begins to rebound, driving the contact plate 504 to squeeze the doors and windows, and then it is separated from the push on the clamping plate 405. After the first compression spring 404 senses the disappearance of pressure, it drives the clamping plate 405 to elastically limit the doors and windows, so that the clamping has a buffering effect, which improves the wrapping limiting effect while improving the convenience of disassembly and assembly.

[0036] For irregular doors and windows, the third motor 306 is started to drive the threaded rod 302 to rotate. While the threaded rod 302 rotates, it drives the two groups of sliding blocks 304 to slide in the sliding cavity 303. While the sliding blocks 304 slide, they drive the two groups of fourth fixed plates 401 to adjust their positions. Then, the fourth motor 307 is started according to the shape of the doors and windows. The fourth motor 307 drives the fourth fixed plate 401 to rotate. After the fourth fixed plate 401 rotates to a specified angle, the irregular doors and windows are limited, thereby improving the limit compatibility effect and the working effect of the auxiliary limit.

[0037] The second electric push rod 203 is started to push the cutting structure 205 to cut the doors and windows, and in order to increase the cutting range, the electric slide 202 can be started to drive the cutting structure 205 to perform translational cutting, thereby expanding the cutting range, and the first motor 201 is started to drive the cutting structure 205 to rotate, thereby increasing the cutting range of the device; before cutting, the fourth electric push rod 514 is started to push the two sets of pressure-resistant plates 520 to move to the bottom of the cutting structure 205, and avoid the output end range of the cutting structure, thereby increasing the passive support stability effect of the structure.

[0038] Based on the above-mentioned door and window cutting device, an embodiment of the present invention further proposes a working method of the door and window cutting device. Exemplarily, the working method includes: Start the top plate assembly to adjust the position; The start-up adjustment component cooperates with the buffer clamping component to limit the position; Start the cutting component to perform cutting; When the cutting structure is offset and cuts the anti-pressure plate, the anti-pressure plate starts to squeeze the sliding rod due to the pressure; The sliding rod begins to squeeze the third compression spring in the sleeve tube during the buffering process, and the third compression spring exerts a rebound force on the pressure sensor when it senses the pressure; When the compression plate is squeezed, the two sets of sensors cannot be located at the same height distance.
