[0029] The principle of implementing the present invention is as follows: the pipe product is transported by the conveyor belt 5, and the installation part 6 positions and installs it. During the transportation process, the push part 4 is controlled by the calibration electric cylinder 3 to push the end of the pipe product for position calibration. When it is located below the rotating shaft 15, the lifting part 17 is controlled by the lifting electric cylinder 16 to lift the pipe product to transfer the pipe product to the positioning mechanism.

[0030] Specifically, the rotation of the rotating shaft 15 can be controlled by the transposition motor 7, and the clamping mechanisms in various directions can fix the pipe product, that is, the crank motor 30 works, the crank disk 29 rotates, and under the connecting action of the connecting rod 31, the clamping mounting plate 25 slides, so that the pipe product is located between the clamping parts 27, and the movement of the clamping parts 27 is controlled by the electromagnetic sliding shaft 26 for clamping.

[0031] By sequentially changing positions, the pipe products are clamped in sequence, and then the pipe products are uniformly transferred to the position of the fixing mechanism. The axial movement of the axial slide 11 is controlled by the stretching control cylinder 18, and the end of the pipe product extends into the inner side of the clamping tube 20 and is fixed by the clamping and fixing cylinder 22.

[0032] After the fixation is completed, the pipe product is inspected. Specifically, when performing hardness testing, the motor 8 works and the screw 9 rotates to move the detection slide 10 to adjust the detection position. The height of the detection mounting seat 34 is controlled by the detection control electric cylinder 33 to make the pipe product located on the inner side of the synthetic inner gear ring 39. The synthetic outer ring 36 is driven by the synthetic motor 35. The two synthetic outer rings 36 are synthesized into a ring shape. Then, the hardness detection cylinder 40 controls the movement of the contact 41 to perform hardness testing, and transmits the detection information to the analysis system. Specifically, during testing, the support cylinder 42 controls the support part 43 to support the pipe product to prevent it from being compressed and deformed.

[0033] For controlled products in different positions, the rotating shaft 15 rotates to transfer the controlled products in different positions to the detection mechanism, and the motor 13 is controlled to work. Under the gear transmission, the gear ring 12 is controlled to rotate, and then the angle gear ring 19 rotates. For the controlled products to be detected, when the angle gear ring 19 rotates, the electromagnetic clamp 1 21 clamps and fixes the outer ring 23 to drive the clamping tube 20 to rotate synchronously. For controlled products in other positions, the electromagnetic clamp 1 21 does not clamp and fix the outer ring 23, and the electromagnetic clamp 2 24 presses the end of the clamping tube 20 to prevent self-rotation; that is, the target controlled products are individually converted in angle to perform hardness detection in various areas of the controlled products; the remaining controlled products are fixed and cannot rotate with the rotation of the angle gear ring 19, so as to facilitate the subsequent determination of the detection position.

[0034] When performing the tensile test, the axial slide 11 is controlled to move by the tensile control cylinder 18, that is, the tensile strength test of the pipe product is performed; and the pipe products in all directions can be stretched at the same time to improve the test efficiency. When the pipe products are unloaded, the pipe products are clamped and transferred by the clamping mechanism, and are transferred to the conveyor belt 5 according to the above transfer process.
