[0031] A large boom 5 clamping fixture includes a machine tool table 1, an end positioning device 2, two main clamping devices 3, and at least one auxiliary clamping device 4. The clamping fixture in this embodiment includes an auxiliary clamping device 4.

[0032] The machine tool worktable 1 is provided with a movable slide guide rail 11 extending along a first direction, and a plurality of movable slide seats 12 are slidably arranged on the movable slide guide rail 11 along the first direction. One main clamping device 3 is installed on the top of the machine tool worktable 1, and another main clamping device 3 is installed on one of the movable slide seats 12, and the line connecting the two main clamping devices 3 is parallel to the first direction.

[0033] Auxiliary clamping devices 4 are arranged between the two main clamping devices 3 and are sequentially arranged on the line connecting the two main clamping devices 3. At least one auxiliary clamping device 4 is slidably mounted on the movable slide rail 11 in the first direction via the remaining movable slide base 12. In this embodiment, three auxiliary clamping devices 4 are directly fixed to the top of the machine tool worktable 1, and one auxiliary clamping device 4 is mounted on the movable slide base 12.

[0034] The end positioning device 2 is installed on the top of the machine tool worktable 1 and is located on the side of the main clamping device 3 fixed on the top of the machine tool worktable 1 away from the other main clamping device 3.

[0035] In this embodiment, the end positioning end is used to abut one end of the boom 5 when clamping the boom 5, and to position the boom 5 in a first direction. Two main clamping devices 3 clamp the two ends of the bottom profile steel on both sides of the boom 5 respectively. Four auxiliary clamping devices 4 clamp the middle part of the bottom profile steel on both sides of the boom 5 respectively, to strengthen the clamping and positioning of the boom 5.

[0036] Specifically, the end positioning mechanism includes a positioning base 21, a positioning cylinder 22, a positioning connecting rod 23, and a stop rod 24. The positioning cylinder 22 is located on one side of the end positioning base 21. One end of the positioning connecting rod 23 is hinged to the piston rod of the positioning cylinder 22, and the other end of the positioning connecting rod 23 is hinged to one end of the stop rod 24 and rotatably connected to the end positioning base 21, so that the other end of the stop rod 24 can be rotated upward to the vertical direction and extend from the top of the positioning base 21, or rotated downward to the horizontal direction and extend to the side of the positioning base 21 away from the main clamping device 3.

[0037] Each main clamping device 3 includes a fixed base 31, a slide base 32, and two main clamping mechanisms 33.

[0038] Each main clamping mechanism 33 includes a support base 331, a main clamping cylinder 332, a main clamping connecting rod 333, a main clamping rod 334, and a guide seat 335.

[0039] The main clamping cylinders 332 are respectively located on the side of the support base 331 away from each other. The piston rod of the main clamping cylinder 332 extends upward and is hinged to the other end of the main clamping rod 334.

[0040] One guide seat 335 is equipped with a vertical guide block 337, and the other guide seat 335 is symmetrically equipped with lateral clamping blocks 338. The vertical guide block 337 and the lateral clamping blocks 338 are respectively located on the side of the two guide seats 335 closest to each other. The lateral clamping blocks 338 are connected to the guide seats 335 through a lateral clamping cylinder 339, which is used to push the lateral clamping blocks 338 in a second direction. An inclined guide block 336 is provided at the top of the side of the guide seats 335 closest to each other. The distance between the two inclined guide blocks 336 gradually increases from bottom to top, guiding both ends of the boom 5 between the lateral clamping blocks 338 and the vertical guide block 337 when the boom 5 moves downward.

[0041] Each auxiliary clamping device 4 includes an auxiliary fixing base 41, an auxiliary slide base 42, and two auxiliary clamping mechanisms 43.

[0042] The auxiliary clamping mechanism 43 also includes an auxiliary support cylinder 431, an auxiliary clamping cylinder 432, an auxiliary clamping rod 434, and an auxiliary clamping connecting rod 433. The auxiliary support cylinder 431, auxiliary clamping cylinder 432, auxiliary clamping rod 434, and auxiliary clamping connecting rod 433 on both sides are symmetrically arranged to clamp the boom 5 between the auxiliary fixed seat 41 and the auxiliary slide seat 42.

[0043] Auxiliary clamping cylinders 432 are respectively located on the side of the auxiliary support cylinders 431 away from each other. The piston rod of the auxiliary clamping cylinder 432 extends upward and is hinged to the other end of the auxiliary clamping rod 434. One end of the auxiliary clamping connecting rod 433 is hinged to the middle of the auxiliary clamping rod 434, and the other end is hinged to the top of the auxiliary clamping cylinder 432, so that one end of the auxiliary clamping rod 434 can be rotated downward to the horizontal direction and positioned above the auxiliary support cylinder 431, thereby pressing the two sides of the boom 5 against the auxiliary support cylinder 431, or rotating upward and moving away from above the auxiliary support cylinder 431, thereby releasing the boom 5.

[0044] The distance between the two main clamping devices 3 in this embodiment can be adjusted according to the length of the boom 5, and the distance between the two main clamping mechanisms 33 on the same main clamping device 3 and the distance between the two auxiliary clamping mechanisms 43 on the same auxiliary clamping device 4 can be adjusted according to the width of the boom 5. This is suitable for the rapid clamping and positioning of large boom 5 parts of various sizes, and solves the problem that there are no suitable clamping fixtures in some situations of large workpieces in the fields of assembly, processing, and welding.

[0045] The usage method of this embodiment is as follows:

[0046] (1) Adjust the position of the main clamping device 3 and the auxiliary clamping device 4 installed on the moving slide rail 11 according to the length of the boom 5 and the position of the support clamping point, and adjust the distance between the two main clamping mechanisms 33 on the same main clamping device 3 and the distance between the two auxiliary clamping mechanisms 43 on the same auxiliary clamping device 4 according to the width of the boom 5.

[0047] (2) Move the boom 5 downward to the clamping position, and the stop bar 24 of the end positioning device 2 extends upward and abuts against one end of the boom 5 to position the boom 5 in the first direction.

[0048] (3) Place both ends of the boom 5 on the support seats 331 of the two clamping devices, and push the side clamping block 338 by the side clamping cylinder 339 to clamp the two sides of the boom 5 between the side clamping block 338 and the vertical guide block 337.

[0049] (4) Adjust each auxiliary support cylinder 431 to support each support clamping point in the middle of the boom 5.

[0050] (5) The main clamping cylinder 332 drives one end of the main clamping rod 334 to rotate downward, thereby pressing the two sides of the boom 5 onto the support seat 331. The auxiliary clamping cylinder 432 drives one end of the auxiliary clamping rod 434 to rotate downward, thereby pressing the two sides of the boom 5 onto the auxiliary support cylinder 431, thus completing the clamping of each support clamping point of the boom 5.
