[0029] like Figure 1-7As shown, an embodiment of the present application provides an automatic end-cutting and chamfering device for an I-beam production line for a steel arch frame. The device can cut and chamfer the ends of the I-beams to be welded, so as to pre-process the welding grooves on the ends of the I-beams to be welded, thereby improving the welding quality of the I-beam joints, ensuring the welding strength at the butt joints of the I-beams, and at the same time meeting the process requirements of using robot welding when welding the I-beams together.

[0030] In some embodiments, the automatic end chamfering device of the I-beam includes a movable seat 2, the movable seat 2 is connected to a rotatable first platform 3, one end of the first platform 3 is hinged with a second drive mechanism 4, the second drive mechanism 4 is used to drive the first platform 3 to rotate, and a lifting mechanism 6 is installed on the first platform 3, the lifting mechanism 6 is connected to a cutting mechanism 7, the lifting mechanism 6 is used to drive the cutting mechanism 7 to lift and lower, the cutting mechanism 7 includes a fourth drive mechanism 71 and a saw blade 73 connected to the fourth drive mechanism 71, the fourth drive mechanism 71 is used to drive the saw blade 73 to rotate to cut the workpiece.

[0031] In some embodiments, a base 1 is further included, wherein the base 1 is provided with a rack 11 and a first guide rail 12, the movable seat 2 is movably connected to the first guide rail 12, and the movable seat 2 is fixedly installed with a first driving mechanism 21, and the output end of the first driving mechanism 21 passes through the movable seat 2 and is connected to a gear 22, and the gear 22 is engaged with the rack 11, and the first driving mechanism 21 is used to drive the gear 22 to rotate so that the movable seat 2 moves along the first guide rail 12 on the base 1.

[0032] In this embodiment, the movable base 2 is movably connected to the base 1 via the first guide rail 12 and can move on the base 1 along the first guide rail 12 under the driving control of the first driving mechanism 21. For example, the first driving mechanism 21 can be a rotary motor, and the fourth driving mechanism 71 can be a rotary motor.

[0033] In some embodiments, the lower portion of the first gantry 3 is mounted on the movable base 2 via a slewing bearing 8 , the second driving mechanism 4 is mounted on the movable base 2 , and the output end of the second driving mechanism 4 is hinged to a corner of the lower end surface of the first gantry 3 .

[0034] In this embodiment, the second driving mechanism 4 drives its output end to extend and retract. Since the output end of the second driving mechanism 4 is hinged to a corner of the lower end surface of the first platform 3, the first platform 3 can rotate on the movable base 2 under the action of the second driving mechanism 4. For example, the second driving mechanism 4 can be a cylinder.

[0035] Furthermore, the interior of the first stand 3 is a hollow structure and is provided with a slope 31. The upper end face and side face of the first stand 3 are provided with openings. The slope 31 connects the two openings. The saw blade 73 is located directly above the opening on the upper end face of the first stand 3. A waste box 32 is provided below the side opening of the first stand 3.

[0036] In this embodiment, the waste box 32 is used to receive the debris, waste, etc. generated by the saw blade 73 when cutting the workpiece. The debris, waste, etc. generated when the saw blade 73 rotates to cut the workpiece falls into the waste box 32 along the slope 31 inside the first stand 3. The debris, waste, etc. are collected by the waste box 32 to ensure that the on-site construction environment is clean.

[0037] In some embodiments, the lifting mechanism 6 includes a lifting column 62 and an elevator 61 installed on the lifting column 62.

The second guide rail 63 is slidably connected to a connecting frame 74, and the connecting frame 74 passes through the slide groove 64 and is connected to the lifting screw rod of the elevator 61.

[0038] In this embodiment, the elevator 61 is mounted on the lifting column 62, and the lifting screw of the elevator 61 is connected to the connecting frame 74.

Alternatively, the connecting frame 74 can pass through the slide 64 via a connecting plate, and the connecting frame 74 is connected to the lifting screw of the elevator 61 via the connecting plate, thereby enabling the elevator 61 to drive the connecting frame 74 to move up and down.

[0039] In some embodiments, the fourth driving mechanism 71 is fixedly connected to the connecting frame 74 ; and a cover 72 is provided outside the saw blade 73 .

[0040] In this embodiment, when the lifter 61 drives the connecting frame 74 to move up and down, the connecting frame 74 drives the entire cutting mechanism 7 to move up and down, thereby realizing that the lifting mechanism 6 drives the cutting mechanism 7 to move up and down.

[0041] In some embodiments, a clamping and positioning mechanism 5 is also installed on the movable seat 2, and the clamping and positioning mechanism 5 includes a second platform 51 arranged on one side of the first platform 3, and the second platform 51 is installed with a third driving mechanism 52, a fixed clamping seat 53, and a movable clamping seat 54. The movable clamping seat 54 is connected to the third driving mechanism 52, and the I-beam 9 is located between the fixed clamping seat 53 and the movable clamping seat 54. The third driving mechanism 52 is used to drive the movable clamping seat 54 to move so that the movable clamping seat 54 moves toward the fixed clamping seat 53, thereby clamping the I-beam 9.

[0042] In this embodiment, the third drive mechanism 52 drives the movable clamping seat 54 to move, thereby clamping and positioning the I-beam 9. Specifically, when the third drive mechanism 52 drives the movable clamping seat 54 toward the fixed clamping seat 53, the distance between the movable clamping seat 54 and the fixed clamping seat 53 decreases, thereby clamping the I-beam 9. When the third drive mechanism 52 drives the movable clamping seat 54 away from the fixed clamping seat 53, the distance between the movable clamping seat 54 and the fixed clamping seat 53 increases, thereby releasing the I-beam 9. For example, the third drive mechanism 52 may be a pneumatic cylinder.

[0043] Furthermore, a rotatable roller 55 is installed on the second stand 51 . The roller 55 is located on one side of the fixed clamping seat 53 , and the I-beam 9 is mounted on the roller 55 .

[0044] During use, the I-beam 9 is fed onto the rollers 55. The movable base 2 is driven by the first drive mechanism 21 to move downward to the set position. The second drive mechanism 4 is activated to rotate the first platform 3 45 degrees. The third drive mechanism 52 of the clamping and positioning mechanism 5 is activated to clamp the I-beam 9. The elevator 61 and the fourth drive mechanism 71 are activated to drive the saw blade 73 to descend and rotate to chamfer the I-beam 9. After the chamfering is completed, the third drive mechanism 52 of the clamping and positioning mechanism 5 is released, the movable base 2 moves, and the second drive mechanism 4 returns to its original position, so that the first platform 3 returns to the original cutting end tangent angle and moves to the cutting end position in parallel. The third drive mechanism 52 of the clamping and positioning mechanism 5 is activated to clamp the I-beam 9. The elevator 61 and the fourth drive mechanism 71 are activated to drive the saw blade 73 to descend and rotate to saw the end of the I-beam 9. After the chamfering and end sawing of the I-beam 9 are completed, the third drive mechanism 52 of the clamping and positioning mechanism 5 is released, and the movable base 2 returns to its initial position.

[0045] In summary, the present application provides an automatic I-beam end cutting and chamfering device for use in a steel arch production line. This device can automatically saw and chamfer the ends of I-beams, pre-processing the weld grooves on the ends of I-beams to be welded, thereby improving the welding quality of I-beam joints and ensuring the weld strength of I-beam butt joints.
