[0022] Embodiment

[0023] Please refer to Figures 1-4 As shown, the present utility model provides a technical solution: a clamping flange fixture with adjustable size;

[0024] A lower seat 3 is slidably installed at the upper end of the workbench 1. A clamping block 4 is closely attached to the upper end of the lower seat 3. A T-shaped groove 5 is formed at the inner end of the clamping block 4. A bolt 6 is threadedly connected to the inner end of the T-shaped groove 5. A moving groove 7 is formed at the lower end of the workbench 1. A connecting member 10 is slidably installed inside the moving groove 7. Four groups of the lower seat 3 and the clamping block 4 are arranged at equal angles, which is convenient for adjusting the position of the clamping block 4 according to different flange diameters, with simple operation and flexible and convenient use;

[0025] A connecting plate 8 is fixedly installed at the upper end of the cylinder 2. Fixed blocks 12 are fixedly installed at equal angles at the upper end of the connecting plate 8. A connecting rod 9 is rotatably installed at the outer end of the fixed block 12. The upper end of the connecting rod 9 is rotatably installed with a connecting member 10, and the connecting member 10 is fixedly installed at the lower end of the lower seat 3. An installation table 11 is fixedly installed at the outer end of the cylinder 2, and the upper end of the installation table 11 is fixedly installed with the workbench 1. The connecting plate 8 is arranged inside the installation table 11, and the installation table 11 is located at the outer lower side of the lower seat 3. Four groups of the connecting rods 9 are arranged at equal angles, and the connecting rods 9 are located below the moving groove 7, which is convenient for quick and accurate clamping and is firm and reliable.

[0026] Specific working principle:

[0027] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, when using this flange fixture with adjustable clamping size, first adjust the position of the clamping block 4 according to the diameter of the flange to be clamped. After adjusting the position of the clamping block 4, the cylinder 2 does not need to be adjusted. The cylinder 2 drives the lower seat 3 to move the same distance, and the purpose of adjusting the clamping size can be achieved. When adjusting the position of the clamping block 4, loosen the bolt 6 upward with a tool, and then the clamping block 4 can be moved backward. To ensure the accuracy of the position movement, the flange can be placed on the upper side of the lower seat 3, that is, placed in the upper center of the workbench 1 to reference and correct the position of the clamping block 4. After moving to the appropriate position, tighten the bolt 6 inside the T-shaped groove 5. After the adjustment of the clamping block 4 is completed, place the flange on the upper side of the lower seat 3 to support it. The output end of the cylinder 2 drives the connecting plate 8 to move downward. When the connecting plate 8 moves downward, it pulls the connecting rod 9 downward through the fixing block 12. The upper end of the connecting rod 9 drives the connecting piece 10 to move inward at the inner end of the moving groove 7. The connecting piece 10 drives the lower seat 3 to move inward on the upper surface of the workbench 1. When the lower seat 3 moves inward, it drives the four groups of clamping blocks 4 to move inward to firmly clamp the flange. The above completes a series of operations of this flange fixture with adjustable clamping size. The content not described in detail in this description belongs to the prior art well-known to those skilled in the art.
