A slide groove 4 is opened at the top of the clamping table 1, and a plurality of slide grooves 4 are opened at the top of the clamping table 1. The first gear 5 is rotatably installed inside the clamping table 1 through a bearing, and a threaded rod 6 is inserted inside the clamping table 1. The threaded rod 6 can pass through the outer surface of the clamping table 1, and the threaded rod 6 passes through the center of the first gear 5 and is threadedly connected with the first gear 5. When the first gear 5 rotates, the threaded rod 6 connected with the thread will be driven to move. The threaded rod 6 is located inside the slide groove 4, and the first gear ring 7 is rotatably installed inside the clamping table 1. The first gear ring 7 is meshed with the first gear 5. When the first gear ring 7 rotates, the meshed first gear 5 is driven to rotate. The bottom of the first gear ring 7 is provided with a groove, and the edge of the groove is designed as an arc surface. The bottom of the first gear ring 7 A metal ball is arranged inside the groove, and several groups of metal balls are arranged inside the groove at the bottom of the first gear ring 7. The metal balls can reduce the contact area between the first gear ring 7 and the inner surface of the clamping table 1, thereby reducing the resistance between the first gear ring 7 and the inner surface of the clamping table 1 when the first gear ring 7 rotates. A second gear ring 8 is fixed on the inner surface of the first gear ring 7, and a driving motor 9 is fixed inside the clamping table 1. A second gear 10 is fixed on the top of the output shaft of the driving motor 9. The driving motor 9 can drive the second gear 10 fixed on the top of the output shaft to rotate. The second gear 10 is meshed with the second gear ring 8. When the second gear 10 rotates, it will drive the meshed second gear ring 8 to rotate. When the second gear ring 8 rotates, it will drive the fixed first gear ring 7 to rotate. The clamping component A is arranged at one end of the threaded rod 6. When the threaded rod 6 moves, it will drive the clamping component A arranged at one end to move. The first gear 5 and the threaded rod 6 are arranged in several groups inside the clamping table 1, and the number of the clamping components A is the same as the number of the threaded rod 6.

[0023] The clamping assembly A includes a first clamping block 11 fixed to one end of the threaded rod 6, a part of the first clamping block 11 is located inside the slide groove 4 and is slidably connected to the slide groove 4, a slot is arranged on the top of the first clamping block 11, a spring 12 is fixed inside the slot, two groups of springs 12 are symmetrically arranged on the top of the first clamping block 11, a limiting column 14 is inserted inside the first clamping block 11, the limiting column 14 can slide inside the first clamping block 11, and a limiting block 15 is fixed to the surface of the limiting column 14, and two groups of limiting blocks 15 are symmetrically fixed on the surface of the limiting column 14, and the limiting block 15 can limit the position of the limiting column 14 to prevent the limiting column 14 from moving from the first clamping block The interior of the block 11 is detached, and the second clamping block 13 is fixed to the top of the limiting column 14. One end of the spring 12 is fixed to the bottom of the slot of the first clamping block 11, and the other end is fixed to the top of the second clamping block 13. The top of the second clamping block 13, the interior of the limiting column 14 and the interior of the first clamping block 11 are provided with threaded holes, and the holes are connected to each other. The fixing bolt 3 is arranged on one side of the top of the spring 12. The fixing bolt 3 can be inserted into the interior of the second clamping block 13 and threadedly connected with the first clamping block 11. When the fixing bolt 3 is threadedly installed in the interior of the first clamping block 11, the surface will contact the top of the second clamping block 13, thereby limiting the position of the second clamping block 13.

[0024] Working principle: when the flange needs to be tapped, the flange is placed on the top of the clamping table 1. At this time, the second gear 10 is driven to rotate by the driving motor 9, and the second gear 10 drives the second gear ring 8 to rotate, so that the second gear ring 8 drives the first gear ring 7 to rotate. When the first gear ring 7 rotates, it will drive several groups of first gears 5 to rotate, so that the first gear 5 drives the threaded rod 6 to move and push the clamping assembly A to move, and the flange is clamped and fixed. At the same time, the equipment can be used for flanges of different sizes and specifications. When clamping, lift the second clamping block 13 and continue Clamping, when the surface of the first clamp block 11 contacts the surface of the flange, loosening the second clamp block 13 can allow the spring 12 to pull the second clamp block 13 to move and make the bottom of the second clamp block 13 contact the top of the flange, thereby auxiliary clamping and fixing the top of the flange by the second clamp block 13, and at the same time, the fixing bolt 3 can be screwed into the interior of the first clamp block 11 so that the bottom of the fixing bolt 3 squeezes the top of the second clamp block 13, thereby strengthening the clamping force of the bottom of the second clamp block 13 on the flange surface and improving the clamping effect. It is relatively convenient to use and has a relatively good clamping effect.
