[0043] The invention will now be described in detail with reference to the accompanying drawings, by way of example. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments.

[0044] like Figure 1As shown, a fully automatic grinding equipment for U-shaped beam steel includes a frame 1, which is a square frame structure welded from multiple horizontal and vertical bars. Hooks 2 are provided at the four corners of the top of the frame 1 to facilitate movement. Material pressure detection devices 3 are provided on both the left and right sides of the frame 1, and a dust collection device 4 is provided at the bottom of the frame 1. Inside the frame 1, from left to right, are arranged a wing surface grinding mechanism 5, a radius angle grinding mechanism 6, and a flank surface grinding mechanism 7. All three mechanisms are bolted to the bottom frame of the frame 1. A drive mechanism 8 is provided between the wing surface grinding mechanism 5 and the R-angle grinding mechanism 6. The drive mechanism 8 is fixedly installed on the bottom frame of the frame 1 via a first bracket 9. A feeding support mechanism 10 is provided between the R-angle grinding mechanism 6 and the ventral surface grinding mechanism 7. The feeding support mechanism 10 is fixedly installed on the bottom frame of the frame 1 via a second bracket 11. The mechanism also includes an upper pressing mechanism 12 and an air knife 13. The upper pressing mechanism 12 is located above the feeding support mechanism 10 and is fixedly connected to the top frame of the frame 1. The air knife 13 is located above the wing surface grinding mechanism 5 and is fixedly connected to the left side frame of the frame 1.

[0045] The workflow of this invention is as follows: The U-shaped beam enters the frame 1 through the pressing and detection device 3 on the left side, and then passes through the wing surface grinding mechanism 5, the drive mechanism 8, the R-angle grinding mechanism 6, the feeding support mechanism 10, and the belly surface grinding mechanism 7 in sequence, before entering the next process through the pressing and detection device 3 on the right side. During the grinding process, the pressing mechanism 12 and the feeding support mechanism 10 cooperate to complete the stable transmission of the U-shaped beam. The air knife 13 can blow the dust off the top surface of the U-shaped beam, and the dust falls into the dust collection device 4 for collection and treatment.

[0046] like Figure 2 As shown, the pressing detection device 3 includes a fixed bracket 301. A hollow square beam 302 is provided at the upper end of the fixed bracket 301. The two ends of the hollow square beam 302 are respectively welded to two columns of the fixed bracket 301. A pressing cylinder 303 is connected to the top of the hollow square beam 302 by screws. The rod of the pressing cylinder 303 extends into the hollow square beam 302 and its head is threadedly connected to a connecting shaft 304. The lower end of the connecting shaft 304 extends out of the hollow square beam 302 and is welded to a first connecting plate 305. The bottom of the first connecting plate 305 is connected to a roller 307 through a mounting base 306. An encoder support 308 is connected to one side of the mounting base 306 by screws. An encoder 309 is installed in the encoder support 308.

[0047] In this technical solution, the pressing cylinder 303 drives the first connecting plate 305 to move downward, which in turn drives the roller 307 to move downward to press the U-shaped beam, ensuring that the U-shaped beam moves forward stably. The encoder 309 is set to facilitate the measurement of the length of the U-shaped beam.

[0048] Furthermore, the bottom of each leg of the fixed bracket 301 is welded with a base plate 310. A through hole is opened in the middle of the base plate 310. A first stud 311 is provided in the through hole. Two nuts 312 are threaded onto the first stud 311. The two nuts 312 are respectively set at the top and bottom of the base plate 310. The bottoms of the two first studs 311 on the same side are welded to the same embedded plate 313.

[0049] In this technical solution, the height of the fixed bracket 301 is adjusted by turning the nut 312 below the base plate 310, while the nut 312 above the base plate 310 is a locking nut used to lock the base plate 310 and the first stud 311 to prevent shaking and affect the pressing effect.

[0050] Furthermore, a shock-absorbing spring 314 is sleeved on the outside of the connecting shaft 304. The upper end of the shock-absorbing spring 314 abuts against the front end of the rod of the pressing cylinder 303, and the lower end abuts against the top surface of the first connecting plate 305.

[0051] Furthermore, a guide tube 315 is welded onto the hollow square beam 302. The guide tubes 315 are symmetrically arranged on both sides of the pressure cylinder 303, with both ends of the guide tubes 315 extending out of the hollow square beam 302. A guide post 316 is installed inside the guide tube 315, and a pad 317 is welded to the bottom of the guide post 316. The pad 317 is connected to the first connecting plate 305 by screws. By setting up the guide tube 315, guide post 316, and pad 317, the movement trajectory of the roller 307 is guided, preventing deviation.

[0052] like Figure 3 As shown, the dust collection device 4 includes a dust collection box 401 and a dust collection trolley 402. The dust collection box 401 is funnel-shaped, and its upper opening is fixedly connected to the bottom of the frame 1 by bolts. The dust collection trolley 402 is located below the dust collection box 401, and the dust collection trolley 402 is provided with a handle 403.

[0053] In this technical solution, the funnel-shaped dust collection box 401 facilitates the automatic falling of dust into the dust collection trolley 402. Pulling the handle 403 pulls out the dust collection trolley 402, making it convenient to handle the dust inside the dust collection trolley 402.

[0054] Furthermore, there are two dust collection boxes 401, which are arranged side by side at the bottom of the frame 1, and the number of dust collection carts 402 matches the number of dust collection boxes 401.

[0055] like Figure 4As shown, the wing surface grinding mechanism 5 includes a wing surface base plate 501. The top of the wing surface base plate 501 is provided with two wing surface grinding components with the same structure. One of the wing surface grinding components is fixedly connected to the top surface of the wing surface base plate 501 by screws. The bottom of the other wing surface grinding component is connected to a wing surface straight module 502 by screws. The wing surface straight module 502 is fixedly connected to the top surface of the wing surface base plate 501 by screws.

[0056] Furthermore, the wing surface grinding component includes a wing surface base 503, with wing surface guide rails 504 connected to both sides of the top of the wing surface base 503 by screws. A wing surface guide rail connecting plate 505 is slidably connected to the wing surface guide rails 504. A wing surface servo motor 506 is provided inside the wing surface base 503. The wing surface servo motor 506 is fixedly connected to the wing surface servo motor mounting base 507 by screws. The wing surface servo motor mounting base 507 is fixedly connected to the wing surface guide rail connecting plate 505 by screws. A splined shaft 509 is connected to the output shaft of the wing surface servo motor 506 through a first coupling 508. A wing surface grinding head 510 is connected to the splined shaft 509. The wing surface grinding head 510 is a copper-plated steel wire wheel or a flap wheel.

[0057] In this technical solution, two wing surface grinding components grind the two wing surfaces of the U-shaped beam respectively. In specific operation, the distance between the two wing surface grinding components is adjusted by the wing surface linear module 502 to suit the beam width of different U-shaped beams. After adjustment, the wing surface servo motor 506 drives the wing surface grinding head 510 to rotate for grinding.

[0058] It also includes a wing cylinder 511, which is fixedly connected to a wing cylinder mounting base 512. The wing cylinder mounting base 512 is fixedly connected to a wing base 503 by bolts. The front end of the rod of the wing cylinder 511 is threadedly connected to a wing floating joint 513, which is connected to a wing guide rail connecting plate 505 by screws.

[0059] In this technical solution, the wing cylinder 511 drives the wing guide rail connecting plate 505 to slide along the wing guide rail 504, which facilitates the local grinding of the U-shaped beam wing surface. After the grinding is completed, the wing cylinder 511 retracts.

[0060] Furthermore, both sides of the bottom of the wing guide rail connecting plate 505 are connected to wing sliders 514 by screws. The two wing sliders 514 are slidably connected to the two wing guide rails 504 respectively. A bearing 515 is provided between the spline shaft 509 and the wing guide rail connecting plate 505. The bearing 515 is fixedly connected to the wing guide rail connecting plate 505 by bolts.

[0061] Furthermore, a grinding shim 516 is connected to the top of the inner groove of the wing-shaped grinding head 510 by a screw. The grinding shim 516 is connected to the spline shaft 509 by a screw. By setting the grinding shim 516, it is beneficial to prevent the grinding head 510 from moving up and down.

[0062] like Figure 5 As shown, the R-angle grinding mechanism 6 includes an R-angle support base plate 601. The top of the R-angle support base plate 601 is provided with two sets of R-angle grinding components with the same structure. The two sets of R-angle grinding components are arranged side by side and in opposite directions.

[0063] Further, the R-angle grinding component includes an R-angle straight module 602, which is fixedly connected to the R-angle support base plate 601 by screws. A module connecting plate 603 is screwed to the top of the R-angle straight module 602, and an R-angle base plate connecting assembly 604 is screwed to the top of the module connecting plate 603. A main guide rail 605 and a guide rail 606 are screwed onto the R-angle base plate connecting assembly 604. The main guide rail 605 and the guide rail 606 are inclined and parallel to each other. A first R-angle slider 607 is slidably connected to the main guide rail 605, and a main guide rail connecting plate 608 is screwed to the top of the first R-angle slider 607. A second R-angle slider 609 is slidably connected to the guide rail 606, and a screw is screwed to the top of the second R-angle slider 609. The system includes a guide rail connecting plate 610 and an R-angle cylinder 611. The R-angle cylinder 611 is located between the main guide rail 605 and the guide rail 606. The front end of the rod of the R-angle cylinder 611 is threadedly connected to an R-angle floating joint 612. An R-angle bearing fixing seat 613 is connected to the R-angle floating joint 612. Both the main guide rail connecting plate 608 and the guide rail connecting plate 610 are connected to the R-angle bearing fixing seat 613. A flange-type seated bearing 614 is bolted to the R-angle bearing fixing seat 613. An R-angle rotating shaft 615 is provided inside the flange-type seated bearing 614. One end of the R-angle rotating shaft 615 is connected to an R-angle servo motor 617 through a second coupling 616, and the other end is connected to an R-angle grinding head 618 through screws. The R-angle grinding head 618 is a copper-plated steel wire wheel or a flap wheel.

[0064] In this technical solution, two R-angle grinding components grind the two R-angles of the U-shaped beam respectively. In specific operation, the distance between the two R-angle grinding components is adjusted by the R-angle linear module 602 to adapt to different beam widths of U-shaped beams. After adjustment, the R-angle servo motor 617 drives the R-angle grinding head 618 to rotate and grind.

[0065] The R-angle cylinder 611 drives the main guide rail connecting plate 608 and the auxiliary guide rail connecting plate 610 to move simultaneously through the R-angle bearing fixing seat 613, which facilitates the local grinding of the R-angle of the U-beam. After grinding is completed, the R-angle cylinder 611 retracts.

[0066] Furthermore, the R-angle cylinder 611 is connected to the cylinder connecting flange 619 by screws, and the cylinder connecting flange 619 is fixedly connected to the R-angle base plate connecting assembly 604 by screws.

[0067] Furthermore, a speed control valve 620 is connected to the speed control interface of the R-angle cylinder 611, which facilitates the adjustment of the air intake speed of the R-angle cylinder 611.

[0070] In this technical solution, two surface grinding components simultaneously grind the surface of the U-shaped beam. During operation, the distance between the two surface grinding components is adjusted by the surface linear module 702 to accommodate different beam widths of the U-shaped beam. After adjustment, the surface servo motor 709 drives the surface grinding head 715 to rotate and grind.

[0071] The ventral cylinder 707 drives the bearing fixing plate 705 to move, which facilitates the grinding of a part of the ventral surface of the U-shaped beam. After the grinding is completed, the ventral cylinder 707 retracts.

[0085] In this technical solution, the feeding support mechanism 10 uses a cylinder to drive the roller assembly to adjust the width, enabling the support and transport of U-shaped beams with different widths. The third and fourth roller assemblies serve as fixed ends. The width adjustment is achieved through the first roller assembly, while the second roller assembly provides support to accommodate different beam widths. In specific applications, the first cylinder 1007 drives the first roller assembly to adjust the width.
