Detailed Description
The following detailed description of the preferred embodiments of the present invention is provided in connection with the accompanying drawings.
As shown in fig. 1-3, a semi-automatic pipe butt weld magnetic memory detection clamp comprises a flange shaft 1, a thrust ball bearing 2, a detection platform 3, a magnetic gauge stand fitting 4, a support base 5 and a direct current speed reduction motor 6; the upper portion of flange axle is passed through thrust ball bearing with the supporting seat is connected, and the upper portion of flange axle is passed the supporting seat and with upper portion testing platform bottom center fixed connection, the lower part installation of flange axle is connected with the action wheel from the driving wheel through the belt, the action wheel is fixed on direct current gear motor's the output shaft, direct current gear motor fixes the inboard of supporting seat, magnetic force table seat accessory is fixed the upper portion of supporting seat, the clamping part at magnetic force table seat accessory is fixed to the binary channels pen type probe of magnetic memory. And a three-jaw chuck is fixed on the detection platform or is directly fixed on the flange shaft. The detection platform is connected with the flange shaft and is driven by the direct current speed reducing motor through the flange shaft. And in the detection process, the rotation of the direct current speed reducing motor is adjusted to realize the rotation of the tubular test piece, the tubular test piece is fixed by the detection probe, and the probe sweeps the metal welding line through the relative rotation of the test piece to obtain the magnetic memory detection information.
The probe can move at all positions in the using process, the internal and external detection requirements of tubular test pieces with various diameters at all heights are met, and therefore the structure of the magnetic gauge stand can be adopted for design. The probe used in the test is a magnetic memory double-channel pen type probe, the magnetic memory double-channel pen type probe is fixed on the clamping part of the magnetic gauge stand fitting, and then the fitting of the magnetic gauge stand clamping part is installed on the supporting seat. The fixation and the actual detection of the probe are realized.
