[0020] Reference Figure 1-Figure 3 A flange hardness testing device for preventing skewness includes a mounting frame 1, a flange body 12, a Leeb hardness tester 17 and a testing mechanism. The bottom inner wall of the mounting frame 1 is fixed with a base 2 by bolts, and the top of the base 2 is fixed with a mounting plate 3 by bolts. One side of the mounting plate 3 is provided with a plurality of sliding holes 4, and a first slider 5 is slidably connected in the sliding hole 4. One end of the first slider 5 is rotatably connected with a clamping rod 8. The circumferential outer wall of the mounting plate 3 is fixed with a plurality of motors 7 by bolts, and the output end of the motor 7 is key-connected with a threaded rod 6, and the threaded rod 6 is threadedly plugged with the first slider 5. The threaded rod 6 rotates under the drive of the motor 7, thereby driving the first slider 5 moves in the slide hole 4, thereby driving the clamping rod 8 to move, and then tightening from the inside of the flange body 12, so that the flange body 12 is fixed. Two first guide rods 11 are welded on one side of the top of the base 2, and a bearing seat 10 is slidably sleeved between the two first guide rods 11. The flange body 12 is clamped on the bearing seat 10, and the bearing seat 10 is pulled to move along the first guide rods 11, thereby driving the flange body 12 to move, so that the lateral center of the flange body 12 is aligned with the Leeb hardness tester 17. A fastening screw 9 is threadedly inserted between the bearing seat 10 and the base 2, and the bearing seat 10 is fixed by the fastening screw 9.

[0021] The detection mechanism includes a pneumatic push rod 19, which is fixed to the top of the mounting frame 1 by bolts. The bottom end of the pneumatic push rod 19 is fixed with a slideway 13 by bolts. The slideway 13 moves downward under the drive of the pneumatic push rod 19, thereby driving the Leeb hardness tester 17 to move downward, and then the hardness of the flange body 12 is tested. A second slider 15 is slidably connected in the slideway 13, and the Leeb hardness tester 17 is fixed to the bottom of the second slider 15 by bolts. An adjusting screw rod 14 is rotatably inserted between the two ends of the slideway 13, and the adjusting screw rod 14 is threadedly inserted with the second slider 15.
