Description

Technical Field

[0001] This utility model belongs to the field of square tube processing technology, specifically relating to a square tube lifting and rotating tooling. Background Technology

[0002] Square tubes are hollow, square-section materials widely used in various fields. Square tube processing primarily involves machining the end faces, ensuring the perpendicularity of the cut end faces to the horizontal direction meets requirements. Current methods involve lifting the square tube using a crane, placing one end on a narrow workbench, and supporting the other end with a pad or other temporary material. Since the required square tube specifications vary, readjustment is necessary when processing different specifications, resulting in slow work efficiency. Furthermore, ensuring the square tube is placed horizontally requires manual measurement of the height at both ends, introducing measurement errors and compromising processing accuracy.

Both the fixed frame 1 and the movable rotating frame 2 are provided with a number of slots 4 of different depths. A load-bearing seat 16 that can rotate relative to the slot 4 is provided in the slot 4. A square tube 15 is placed above the load-bearing seat 16.

[0026] It should be noted that by placing the support seat 16 in the slots 4 of different depths, the square tube 15 above the support seat 16 can be quickly adjusted to the required height, improving work efficiency; the movable rotating frame 2 can slide along the fixed frame 1, supporting square tubes 15 of different lengths to meet the processing needs of square tubes of different specifications; the fixed frame 1 and the movable rotating frame 2 are respectively provided with slots 4 to ensure the horizontality of the square tube 15, which helps to improve processing accuracy; the movable rotating frame 2 can rotate relative to the fixed frame 1, so when changing the other end face of the square tube 15 for processing, there is no need to use a crane to lift it again, it can be rotated directly, making operation convenient.

[0027] In the square tube lifting and rotating fixture of this embodiment, please refer to... Figures 1 to 6The load-bearing base 16 includes a load-bearing rotating shaft and a load-bearing wheel. The load-bearing wheel and the load-bearing rotating shaft are coaxially arranged and can rotate relative to each other. The load-bearing rotating shaft is embedded in the slot 4.

[0028] It should be noted that the square tube 15 is placed on the load-bearing wheel, which rotates relative to the load-bearing shaft, making it convenient for the square tube 15 to move back and forth; the surface of the load-bearing wheel is provided with a receiving groove to accommodate the square tube 15, so as to improve the stability of the square tube 15.

[0029] It is particularly important to note that the different depths of the slots 4 help to quickly adjust the square tube 15 to the required height; the top of the fixed frame 1 and the top of the movable rotating frame 2 are on the same horizontal plane, and the depths of the slots on the fixed frame 1 and the slots 4 on the movable rotating frame 2 are set to correspond to each other to ensure the horizontality of the square tube 15; multiple sets of slots 4 of different depths can be set along the length of the fixed frame 1 and / or the movable rotating frame 2 to provide multi-point support for the square tube 15.

[0030] In the square tube lifting and rotating fixture of this embodiment, please refer to... Figures 1 to 6 The fixed frame 1 and the movable rotating frame 2 are symmetrically arranged in twos, and the two fixed frames 1 and the two movable rotating frames 2 are connected by a connecting plate 3.

[0031] It should be noted that the connecting plate 3 integrates two symmetrically arranged fixed frames 1 into one unit. At the same time, the connecting plate 3 can also integrate two symmetrically arranged movable rotating frames 2 into one unit. The connecting component is located between the two fixed frames 1, and the movable rotating frame 2 is located above the fixed frame 1.

[0032] In the square tube lifting and rotating fixture of this embodiment, please refer to... Figures 1 to 6 The connecting component includes a slider 9 and a rotating shaft 6. The slider 9 is located between two fixed frames 1 and can slide along the length of the fixed frames 1. The rotating shaft 6 passes through the slider 9 and is connected to the movable rotating frame 2. The rotating shaft 6 can rotate relative to the slider 9.

[0033] It should be noted that the slider 9 has a receiving cavity inside, and the rotating shaft 6 is located inside the receiving cavity. At the same time, a bearing is provided between the rotating shaft 6 and the receiving cavity, so that the rotating shaft 6 can rotate relative to the slider 9. The top of the rotating shaft 6 is connected to the movable rotating frame 2, so that the rotating shaft 6 drives the movable rotating frame 2 to rotate.

[0034] In the square tube lifting and rotating fixture of this embodiment, please refer to... Figures 1 to 6 A wear-resistant pad is provided at the junction of the slider 9 and the fixed frame 1.

[0035] It should be noted that the top of the slider 9 overlaps the fixed frame 1, and a wear-resistant pad is provided at the junction of the slider 9 and the fixed frame 1. As the slider 9 moves along the fixed frame 1, the wear-resistant pad can reduce the wear of the fixed frame 1 on the slider 9.

[0036] In the square tube lifting and rotating fixture of this embodiment, please refer to... Figures 1 to 6 The top of the rotating shaft 6 is provided with a shaft platform 10, and a through hole for accommodating the rotating shaft 6 is opened on the base plate 17 located between the two movable rotating frames 2. The shaft platform 10 and the base plate 17 are connected by a connector, and an anti-loosening nut is provided at the bottom of the rotating shaft 6.

[0037] It should be noted that the anti-loosening nut can prevent the rotating shaft 6 from separating from the slider 9; the movable rotating frame 2 and the rotating shaft 6 are integrated into one unit using the shaft platform 10 and the base plate 17.

[0038] In the square tube lifting and rotating fixture of this embodiment, please refer to... Figures 1 to 6 The slider 9 is provided with a locking latch 11 on its side. The locking latch 11 is provided with a screw 12 that passes through it. The bottom of the screw 12 passes through a locking seat 13 and is connected to a rotating handle 14. The locking seat 13 can be engaged with the bottom of the fixed frame 1.

[0039] It should be noted that after placing the connecting component between the two fixed frames 1 and moving the connecting component to the appropriate position along the fixed frames 1, the screw 12 is turned to change the vertical distance between the locking latch 11 and the locking seat 13, causing the locking seat 13 to engage with the bottom of the fixed frame 1, thereby locking the position of the connecting component.

[0040] In the square tube lifting and rotating fixture of this embodiment, please refer to... Figures 1 to 6 The fixed frame 1 is provided with a scale 5 extending along its length, which facilitates the quantification of the movement of the connecting components along the fixed frame 1.
