When the limiting guide side rollers 28 contact the steel plate, they stop moving, so that the position of the chamfering scraper disc 6 can be adjusted synchronously.

[0030] Embodiment 2, this embodiment is based on the previous embodiment, such as Figure 1-Figure 2 , Figure 4-Figure 8 as well as Figure 11-Figure 12 As shown, a connecting horizontal plate 2 34 is fixedly provided between the supporting vertical plate 32 on the mounting platform 2 on one side and the supporting vertical plate 32 on the mounting platform 2 on the other side, a gantry 8 is fixedly provided on the upper side of the connecting horizontal plate 2 34, the gantry 8 is fixedly provided on the upper wall of the base 1, a cylinder 22 is fixedly provided on the top wall of the gantry 8, a mounting clamp 40 is fixedly provided on the side wall of the gantry 8, a transmission pipe 16 is fixedly provided in the mounting clamp 40, one end of the transmission pipe 16 is through-connected with the base end of the cylinder 22, an airflow temporary storage cylinder 15 is horizontally fixedly provided on the side wall of the gantry 8, a piston 14 is movably provided in the airflow temporary storage cylinder 15, a mounting frame 7 is fixedly provided on the outer wall of the fixed guide platform 3 on one side, a friction disk 17 is rotatably provided in the mounting frame 7, and a fixed sleeve is provided on the circumferential outer wall of the friction disk 17 A driving gear 12 is provided, and a driving rack rod 13 is horizontally slidably provided on the inner wall of the mounting frame 7, the driving rack rod 13 is meshed with the driving gear 12, one end of the driving rack rod 13 is fixedly connected to the piston 14, a guide rod 20 is rotatably provided on the outer wall of the fixed guide platform 3, one end of the guide rod 20 is coaxially fixedly connected to one end of the bidirectional screw 9, a friction disc 2 18 is provided on the circumferential outer wall of the guide rod 20 by a snap-on sliding sleeve, a spring 19 is provided on the outer side of the guide rod 20, one end of the spring 19 is movably in contact with the side wall of the friction disc 2 18, and the other end of the spring 19 is movably in contact with the outer wall of the fixed guide platform 3, the side walls of the friction disc 17 and the friction disc 2 18 facing each other are movably in contact, and the wall surfaces of the two side walls in contact with the friction disc 17 and the friction disc 2 18 are both provided with a frosted layer.

[0031] Working process: first activate the rotation drive source to make the friction disc 17 and the friction disc 2 18 rotate synchronously. When the limiting guide side roller 28 contacts the steel plate, the friction disc 2 18 stops rotating, so the friction disc 17 will produce friction movement relative to the friction disc 2 18. At this time, the friction disc 17 drives the driving gear 12 to rotate, and the driving gear 12 drives the piston 14 to move into the airflow temporary storage cylinder 15 by driving the rack rod 13. In this process, the airflow in the airflow temporary storage cylinder 15 is guided to the cylinder 22 through the transmission pipe 16, so that the output end of the cylinder 22 extends, thereby realizing the positioning of the upper and lower walls of the steel plate.

[0032] Embodiment 3, this embodiment is based on the previous embodiment, such as Figure 1-Figure 12 As shown, an installation sliding groove 31 is provided through-type in the support vertical plate 32, and an installation sliding plate 30 is vertically slidably provided in the installation sliding groove 31, and a downward pressure shaft rod 24 is rotatably provided on the opposite side walls of the two installation sliding plates 30 on the same installation platform 2, and both ends of the downward pressure shaft rod 24 pass through the installation sliding groove 31, and a moving motor 29 is fixedly provided on the outer wall of one of the installation sliding plates 30, and the output end of the moving motor 29 is coaxially fixedly connected with one end of the downward pressure shaft rod 24, and a conveying moving roller 25 is fixedly sleeved on the circumferential outer wall of the downward pressure shaft rod 24, and a fixed shaft rod 26 is rotatably provided on the opposite side walls of the two support vertical plates 32 on the same installation platform 2, and a placement load-bearing roller 27 is fixedly sleeved on the circumferential outer wall of the fixed shaft rod 26, and the placement load-bearing roller 27 corresponds to the conveying moving roller 25 up and down.

[0033] An adapter block 39 is symmetrically rotatably provided on the pressing shaft rod 24 , and a connecting frame 23 is fixedly provided at the output end of the cylinder 22 . The connecting frame 23 is arranged in an H shape, and the four end points of the connecting frame 23 are fixedly connected to the adapter block 39 respectively.

[0034] The chamfering scraping blade disc 6 is provided with scraping plates 36 in an annular array on the circumferential side wall thereof, and the scraping plates 36 are provided with chamfering scraping arc grooves 35 on the inner sides thereof.

[0035] A downward pressure driving motor 21 is fixedly provided on the outer side wall of the mounting frame 7 , and an output end of the downward pressure driving motor 21 is coaxially fixedly connected to the friction disk 17 .

[0036] Working process: when the output end of the cylinder 22 is extended, the conveying moving roller 25 will contact the upper surface of the strip steel plate, and then the scraping motor 5 will be started to drive the chamfering scraping disc 6 to rotate, and the moving motor 29 will be activated to rotate the lower pressure shaft 24 and the conveying moving roller 25. The rotation of the conveying moving roller 25 will drive the strip steel plate to move along the guide of the conveying platform 33 and the limiting guide side roller 28. At this time, the arc groove 35 of the chamfering scraping disc 6 accurately scrapes the edge of the strip steel plate, thereby realizing the chamfering of the edge of the strip steel plate.

[0037] When in use, first, place the strip steel plate steadily on the side conveying table 33, then manually push the steel plate to position it between the limiting guide side rollers 28, then activate the downward pressure drive motor 21, the drive motor 21 drives the friction disc 17 to rotate, because the friction coefficient between the friction disc 17 and the friction disc 2 is relatively high, the friction disc 17 can effectively drive the friction disc 2 18 to rotate, the friction disc 2 18 drives the bidirectional screw 9 to rotate, the bidirectional screw 9 drives the connecting block 10 to move toward the middle at the same time, and the connecting block 10 drives the sliding adjustment frame 4 on both sides and the connecting cross plate 11 to move toward the center synchronously; When the limiting guide side roller 28 contacts the two side walls of the strip steel plate, the limiting guide side roller 28 stops moving. At this time, the position of the chamfering scraping blade 6 is also accurately adjusted. The downward pressure driving motor 21 continues to rotate. Since the limiting guide side roller 28 has contacted the side wall of the steel plate, the friction disc 2 18 will stop rotating, so the friction disc 1 17 will produce friction movement relative to the friction disc 2 18. The friction disc 1 17 drives the driving gear 12 to rotate. The driving gear 12 drives the piston 14 to move into the airflow temporary storage cylinder 15 by driving the rack rod 13. In this process, the airflow in the airflow temporary storage cylinder 15 is guided into the cylinder 22 through the transmission pipe 16, so that the output end of the cylinder 22 extends, thereby pushing the connecting frame 23, the adapter block 39 and the downward pressure shaft rod 24 to move downward; When the conveying moving roller 25 contacts the upper surface of the strip steel plate, the operation of the downward pressure driving motor 21 is stopped, and then the scraping motor 5 is started to drive the chamfering scraping disc 6 to rotate, and the moving motor 29 is activated to rotate the downward pressure shaft 24 and the conveying moving roller 25. The rotation of the conveying moving roller 25 will drive the strip steel plate to move along the guide of the conveying platform 33 and the limiting guide side roller 28. At this time, the arc groove 35 of the chamfering scraping disc 6 accurately scrapes the edge of the strip steel plate, thereby realizing the chamfering processing of the edge of the strip steel plate.

[0038] The present invention and its embodiments are described above, which is not restrictive. What is shown in the accompanying drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and do not deviate from the purpose of the invention, they can creatively design structural methods and embodiments similar to the technical solution, which should all fall within the scope of protection of the present invention.
