[0028] Please refer to Figures 1-3 As shown in the figure, this embodiment is a quick positioning tooling for a workpiece with holes, including:

[0029] A tooling component, the tooling component includes a tooling body 11;

[0030] The tooling component further includes a placing groove 12, and the placing groove 12 is opened at an internal position of the tooling body 11;

[0031] The tooling body 11 is used to fix the workpiece, and the placing groove 12 is used to place the workpiece.

[0032] The movable component includes a movable ring 21, a support ring 22, a fixed block 23, a first fixed shaft 24, a connecting rod 25, a second fixed shaft 26, and a clamping block 27. The movable ring 21 is threadedly connected to the outer surface of the tooling body 11. The support ring 22 is sleeved on the upper end inside the movable ring 21. The fixed block 23 is fixedly connected to the upper end periphery of the support ring 22. The first fixed shaft 24 is fixedly connected to the inside of the fixed block 23. The connecting rod 25 is sleeved on the outer surface of the first fixed shaft 24. The second fixed shaft 26 is sleeved on the other end inside of the connecting rod 25. The clamping block 27 is sleeved on the central outer surface of the second fixed shaft 26;

[0033] The movable ring 21 is used to drive the support ring 22 to move up and down. The support ring 22 is used to support the fixed block 23. The fixed block 23 is used to support the first fixed shaft 24. The first fixed shaft 24 and the second fixed shaft 26 are used to support both ends of the connecting rod 25. The connecting rod 25 is used to drive the second fixed shaft 26 to move. The second fixed shaft 26 is used to drive the clamping block 27 to move. The clamping block 27 is used to clamp and fix the workpiece.

[0034] Corresponding thread structures are provided on the inner surface of the movable ring 21 and the outer surface of the tooling body 11, and the support ring 22 is of an I-shaped structure;

[0035] When the movable ring 21 rotates, the support ring 22 will not rotate with the movable ring 21. And when the movable ring 21 moves up and down, it will drive the support ring 22 to move up and down.

[0036] The clamping block 27 penetrates through the upper end periphery of the tooling body 11, and the connecting rod 25 is located on both outer sides of the clamping block 27;

[0037] The clamping block 27 can move inside the upper end of the tooling body 11.

[0038] Working principle: When it is necessary to clamp and fix the workpiece, the workpiece is placed into the placement groove 12, and a rotational force is applied to the movable ring 21, so that the movable ring 21 moves downward under the drive of the thread structure. The downward movement of the movable ring 21 drives the support ring 22 to move downward. The support ring 22 drives the fixed block 23 to move downward. The fixed block 23 drives the first fixed shaft 24 to move downward. The first fixed shaft 24 drives the connecting rod 25 to rotate inward. The connecting rod 25 drives the second fixed shaft 26 to move inward, so that the second fixed shaft 26 drives the clamping block 27 to move inward, thereby enabling the clamping block 27 to move to the inside of the upper end of the tooling body 11 to clamp the outer side of the workpiece; When it is necessary to remove the workpiece, reverse the above steps.

[0039] Please refer to Figure 4 As shown, this embodiment further includes, on the basis of the above embodiment:

[0040] The positioning component includes a fixing groove 31, a fixing post 32 and a positioning rod 33. The fixing groove 31 is opened at one side inside the tooling body 11, the fixing post 32 is threadedly connected to the inside of the fixing groove 31, and the positioning rod 33 is fixedly connected to the outer end of the fixing post 32;

[0041] The fixing groove 31 is used to limit the fixing post 32, the fixing post 32 is used to support the positioning rod 33, and the positioning rod 33 is used to guide the perforated workpiece.

[0042] The inner surface of the fixing groove 31 and the outer surface of the fixing post 32 are provided with corresponding thread structures, and the positioning rod 33 penetrates through the tooling body 11 and extends upward;

[0043] The fixing post 32 can be fixed inside the fixing groove 31 driven by the thread structure, or can be taken out from the inside of the fixing groove 31 along the thread structure.

[0044] Working principle: When it is necessary to guide and position the perforated workpiece, the fixing post 32 is fixed inside the fixing groove 31 through the thread structure, so that the positioning rod 33 is fixed at the upper end inside the tooling body 11 and extends outward. By placing the hole of the perforated workpiece corresponding to the positioning rod 33, the perforated workpiece can be guided and positioned. When it is necessary to guide holes with different sizes, by rotating the fixing post 32, the fixing post 32 is taken out from the inside of the fixing groove 31, and thus different sizes of positioning rods 33 can be replaced.
