[0003] However, the existing fully automatic cold centering hole processing equipment for steel billets has some problems in use. The existing equipment is not convenient to adjust its height and is not easy to adapt to conveying equipment of different heights. At the same time, the existing equipment is not convenient to clamp and limit the steel billet, which may cause displacement during processing. In addition, it is not convenient to suck up and collect the debris generated during processing. Summary of the Invention

A movable rod is provided through the vertical grooves. The support plate has clamps near the front and rear sides at the bottom. The bottom end of the movable rod passes through the top of the adjacent clamp and is fixedly connected to a first connecting plate. The top end of the movable rod is fixedly connected to a second connecting plate, which is located at the top of the support plate.

[0007] Preferably, sliders are fixedly connected to the top of both sides of the movable rod, and the sliders are movably connected in adjacent grooves. Vertical plates are fixedly connected to the top of the second connecting plate, and a first spring is fixedly connected between two adjacent vertical plates. Grooves are provided on both sides of the vertical plates, and elastic collars are fitted on the outer edges of two adjacent vertical plates, with the elastic collars located in the grooves.

[0008] Preferably, a conical annular frame is fitted around the outer edge of the motor, and a fixing tube is provided through the front and rear sides of the conical annular frame near the top and fixedly connected thereto. A second flange is fixedly connected to the outer edge of the fixing tube away from the conical annular frame.

[0009] Preferably, a second L-shaped plate is fixedly connected to both the front and rear sides of the limiting ring. A T-shaped groove is opened on one side of each of the second L-shaped plates. A T-shaped block is movably connected in each of the T-shaped grooves. A second spring is fixedly connected to the top of each T-shaped block. The top of the second spring is fixedly connected to the top of the T-shaped groove. A vacuum cleaner is fixedly connected to the side of each T-shaped block away from the motor. A hose is fixedly connected to the top of each vacuum cleaner. The end of the hose away from the vacuum cleaner is attached to one end of an adjacent fixed pipe. A first flange is fixedly connected to the outer edge of the hose away from the vacuum cleaner.

[0010] Preferably, the first flange and the second flange are fitted together, and each of the first flange and the second flange has four second threaded holes, with bolts threaded into two adjacent second threaded holes.

[0011] Preferably, four lifting rings are fixedly connected to the top of the support plate, and first L-shaped plates are fixedly connected to the front and rear sides of the support plate near the left and right sides. Movable plates are attached to the side of the first L-shaped plates away from the support plate. A base plate is fixedly connected to the bottom of each movable plate. A blind groove is formed on the side of each movable plate away from the base plate. Movable grooves are formed on the left and right sides of each blind groove. A limiting plate is provided in each blind groove. The top of the limiting plate is fixedly connected to one side of the adjacent first L-shaped plate. Movable blocks are fixedly connected to the left and right sides of the limiting plate near the bottom. The movable blocks are movably connected in the adjacent movable grooves.

[0012] Preferably, a cylinder is provided between the two first L-shaped plates. A first crossbar is fixedly connected to the top of each cylinder on both sides. The end of the first crossbar away from the cylinder is inserted into the side of the adjacent first L-shaped plate. A second crossbar is fixedly connected to the bottom of each cylinder on both sides. The end of the second crossbar away from the cylinder is fixedly connected to the side of the adjacent movable plate. A through groove is opened at the top of the bottom plate near both sides, and a roller is inserted into each through groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention, through the coordinated operation of hydraulic cylinders, clamping plates, motors, and composite drill bits, enables the following functionality when adapting to conveying equipment of varying heights: Activating the cylinder moves the movable plate downwards via a second crossbar. The movable plate then moves the base plate and rollers downwards until the bottom of the rollers contacts the ground, ensuring that the first L-shaped plate and the limiting plate do not detach from the movable plate. This limits the support plate, allowing the conveying equipment to transport the steel billet. One side of the billet will first contact the clamping plate. Since both sides of the clamping plate are inclined, the billet will enter between the inclined surfaces of the two clamping plates. Under the operation of the conveying equipment, the two clamping plates are gradually opened, and the billet enters the space between them. The clamping plates will then stretch the first spring and elastic collar, ensuring that the clamping plates can always hold billets of different sizes. The system consists of a hydraulic cylinder and a servo motor. The hydraulic cylinder drives the composite drill bit downwards, while the motor drives the composite drill bit to rotate, drilling holes in the steel billet. When the transmission rod rotates forward, it drives the rotating plate to rotate, which in turn drives the limiting ring to rotate. The limiting ring then drives the second L-shaped plate to rotate, which in turn drives the vacuum cleaner to rotate. The vacuum cleaner then drives the conical ring frame to rotate, which rotates on the motor surface. When the motor controls the transmission rod to rotate in reverse, the transmission rod drives the rotating plate to rotate in reverse. During this time, the limiting ring will have a certain period of inactivity, preventing it from rotating. This allows the vacuum cleaner to rotate intermittently. When the vacuum cleaner is activated, it absorbs iron filings from the drilled holes on the steel billet surface. The iron filings enter the conical ring frame through the hose and fixed tube.

A second flange 38 is fixedly connected to the outer edge of the fixed tube 37 away from the conical ring frame 20. The limiting ring 27 is fixedly connected to the front and rear sides with second L-shaped plates 29. Each of the second L-shaped plates 29 has a T-slot on one side, and a T-shaped block 34 is movably connected within each T-slot. A second spring 35 is fixedly connected to the top of each T-block 34, and the top of the second spring 35 is fixedly connected to the top of the T-slot.

Four second threaded holes are opened on both the first flange 32 and the second flange 38. A bolt 33 is threaded into two adjacent second threaded holes. Four lifting rings 7 are fixedly connected to the top of the support plate 1. The first L-shaped plates 34 are fixedly connected to the front and rear sides of the support plate 1 near the left and right sides. A movable plate 4 is attached to the side of an L-shaped plate 3 away from the support plate 1. A base plate 5 is fixedly connected to the bottom of each movable plate 4. A blind groove is opened on the side of the movable plate 4 away from the base plate 5. Movable grooves are opened on both the left and right sides of the blind groove. A limiting plate 18 is provided in each blind groove. The top of the limiting plate 18 is fixedly connected to one side of the adjacent first L-shaped plate 3. Movable blocks 36 are fixedly connected to the bottom of the left and right sides of the limiting plate 18. The movable blocks 36 are movably connected in the adjacent movable grooves. A cylinder 15 is provided between the two first L-shaped plates 3. A first crossbar 16 is fixedly connected to the top of the left and right sides of the cylinder 15. The end of the first crossbar 16 away from the cylinder 15 is inserted into one side of the adjacent first L-shaped plate 3. A second crossbar 17 is fixedly connected to the bottom of the left and right sides of the cylinder 15. The end of the second crossbar 17 away from the cylinder 15 is fixedly connected to one side of the adjacent movable plate 4. A through groove is opened on the top of the base plate 5 near the left and right sides. Rollers 19 are inserted into the through grooves.

[0017] Working principle: When the device starts working, the crane moves the device via the lifting ring 7 and places it on the conveying equipment. If it needs to be adapted to conveying equipment of different heights, the cylinder 15 is activated. The cylinder 15 drives the movable plate 4 downward via the second crossbar 17. The movable plate 4 drives the base plate 5 and roller 19 downward until the bottom of the roller 19 contacts the ground. The limiting plate 18 moves in the blind groove inside the movable plate 4, and the movable block 36 moves in the movable groove on the inner wall of the blind groove, thereby ensuring that the first L-shaped plate 3 and the limiting plate 18 do not detach from the movable plate 4, thus limiting the support plate 1. The bottom of the clamping plate 6 is located above the conveying equipment, and the conveying equipment drives the steel billet to move... During conveying, one side of the billet will first contact one side of the clamping plate 6. Since both sides of the clamping plate 6 are inclined, the billet will enter between the inclined surfaces of the two clamping plates 6. Under the operation of the conveying equipment, the two clamping plates 6 will gradually open up and the billet will enter between them. The clamping plate 6 will drive the movable rod 8 to move, which in turn drives the first connecting plate 9 to move, and then the second connecting plate 11 to move. The movable rod 8 will drive the slider 10 to move, and the second connecting plate 11 will drive the vertical plate 12 to move. The vertical plate 12 will then drive the first spring 13 and the elastic collar 14 to stretch, thereby ensuring that the clamping plate 6 can always clamp billets of different sizes. When the billet moves to the re-clamping plate 6... When the composite drill bit 24 is below, the conveying equipment is shut off, and the hydraulic cylinder 2 and motor 21 are started simultaneously. Motor 21 is a servo motor. The hydraulic cylinder 2 drives motor 21 to move downward, and motor 21 drives composite drill bit 24 to move downward. Motor 21 drives transmission rod 22 to rotate, and transmission rod 22 drives composite drill bit 24 to rotate. Composite drill bit 24 drills holes in the steel billet. When transmission rod 22 rotates forward, it drives rotating plate 23 to rotate. Rotating plate 23 drives fixed plate 28 to rotate, fixed plate 28 drives limit ring 27 to rotate, and limit ring 27 drives second L-shaped plate 29 to rotate. Second L-shaped plate 29 drives vacuum cleaner through T-block 34. The vacuum cleaner 30 rotates, and the fixed tube 37 rotates through the hose 31, the first flange 32, the second flange 38 and the bolt 33. The fixed tube 37 rotates the conical ring frame 20. The conical ring frame 20 rotates on the surface of the motor 21. When the motor 21 controls the transmission rod 22 to reverse, the transmission rod 22 drives the rotating plate 23 to reverse. At this time, the limit ring 27 will have a certain period of inactivity and cannot rotate, thus realizing the intermittent rotation of the vacuum cleaner 30. When the vacuum cleaner 30 is started, it absorbs the iron filings at the drilled holes on the surface of the steel billet. The iron filings enter the conical ring frame 20 through the hose 31 and the fixed tube 37. If it is necessary to disassemble the conical ring frame 20, the device stops working and the motor 21 is rotated. The motor 21 drives the threaded rod 25 to rotate. The threaded rod 25 moves out from the threaded hole at the bottom of the hydraulic cylinder 2, and the motor 21 is disassembled. Then, the bolt 33 is rotated and removed from the first flange 32 and the second flange 38, so that the conical ring frame 20 can be removed from the surface of the motor 21.
