[0022] Reference Figures 1-4 A flange processing fixture includes a support 1. A clearance opening 2 is provided on one side of the support 1. A rotating disk 4 is rotatably connected within the clearance opening 2. Multiple sliding grooves 5 arranged in a circular array are provided on the rotating disk 4. Sliding blocks 17 are slidably connected within each of the multiple sliding grooves 5. A clamping block 6 is bolted to one side of each sliding block 17. Two symmetrical second fixing plates 12 are bolted to the other side of each sliding block 17. A lead screw 7 is rotatably connected to one side of the rotating disk 4 via a bearing. A triangular block 9 is threaded onto the lead screw 7. Multiple sets of first fixing plates 10, each set consisting of two plates, are bolted to the triangular block 9. A connecting rod 11 is rotatably connected between the two first fixing plates 10, and the other end of the connecting rod 11 is rotatably connected to the second fixing plate 12. Through the clearance opening 2 and the rotating disk 4, the flange can be fixed by the clamping block 6. After initial processing, rotating the rotating disk 4 allows the flange to be rotated, enabling processing of different positions on the flange.

[0023] In this invention, a limiting groove 13 is provided on the inner circumference of the clearance opening 2, and a limiting ring 14 is fixedly connected to the outer circumference of the rotating disk 4 by bolts. The limiting ring 14 is slidably connected within the limiting groove 13. The limiting ring 14 and the limiting groove 13 can limit the rotation of the rotating disk 4. A plurality of locking holes 16 arranged in a circular array are provided on the outer circumference of the limiting ring 14. A clearance hole 15 is provided on one side of the bracket 1. An insert rod 18 is slidably connected within the clearance hole 15, and one end of the insert rod 18 passes through the clearance hole 15 and is embedded into one of the locking holes 16. With the locking holes 16 and the insert rod 18, after the rotating disk 4 rotates, one end of the insert rod 18 can be inserted into one of the locking holes. In section 16, the rotating disk 4 can be fixed to prevent it from rotating on its own during processing, which would cause the flange position to change. The outer circumference of the rotating disk 4 is fixedly connected to the scale 3 by bolts. One side of the bracket 1 is fixedly connected to the pointer 20 by bolts, and one side of the pointer 20 is in contact with the scale 3. One side of the insertion rod 18 is fixedly connected to the tension spring 19 by bolts. The other end of the tension spring 19 is fixed to one side of the bracket 1, and the tension spring 19 is sleeved on the outside of the insertion rod 18. One end of the lead screw 7 is fixedly connected to the knob 8 by bolts. Multiple grooves in a circular array are opened on the outer circumference of the knob 8. A slide rod is welded between the inner walls of the two sides of the slide groove 5, and the slide rod passes through the slider 17 and is slidably connected to it.

[0024] The use of this utility model involves the following steps:

[0025] S1: When the flange needs to be processed, first place the flange on one side of the rotating disk 4, then rotate the screw 7 to drive the triangular block 9 to move along the screw 7, and through the connecting plate drive the slider 17 to move along the slide groove 5 towards the center of the rotating disk 4, and then drive the clamping block 6 to move towards the position close to the flange. After it contacts the flange, the flange is fixed.

[0026] S2: After the initial processing is completed, pull the insert rod 18 upward along the clearance hole 15. When the bottom end of the insert rod 18 is disengaged from the locking hole 16, the rotating disk 4 can be rotated. After the adjustment is completed, release the insert rod 18. The tension spring 19 pulls the insert rod 18 downward along the clearance hole 15 until the bottom end of the insert rod 18 is embedded in the corresponding locking hole 16, thus completing the rotation of the flange.

[0027] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
