Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Such as figure 1 As shown, the present invention discloses a clamping device for a cavitation water jet surface strengthening treatment test, which is suitable for a test piece 1 with a penetrating structure of a nuclear power plant pressure vessel. The clamping device of the present invention includes a horizontal console 2 that can move along the XY plane (that is, the horizontal console 2 can control the displacement of the X-axis and the Y-axis on the horizontal plane), a second horizontal console that extends along the Z-axis and can be lifted along the Z-axis. A shaft 3, a second shaft 4 that is arranged above the first shaft 3 and can rotate along its own axis, a third shaft 5 that can rotate relative to the second shaft 4 in the XZ plane, and a third shaft that can rotate relative to the third shaft in the XZ plane The fourth shaft 6 tha...

Abstract

The invention relates to the technical field of cavitation water jet surface strengthening, and specifically relates to a clamping device for a cavitation water jet surface strengthening treatment test. The clamping device comprises a horizontal control platform capable of moving along a XY plane, a first shaft extending along a Z shaft and being capable of ascending and descending along the Z shaft, a second shaft arranged above the first shaft and being capable of rotating along an axis line of the second shaft, a third shaft capable of rotating relative to the second shaft in a XZ plane orYZ plane, a fourth shaft capable of rotating relative to the third shaft in the XZ plane or the YZ plane, and a fifth shaft connected with the fourth shaft and being capable of rotating along an axisline of the fifth shaft, and the upper end of the fifth shaft is connected with a clamping tool for clamping a test piece. The clamping device can adjust the position and angle of the test piece and has a rotation function, so as to conveniently perform cavitation water jet strengthening treatment on a test piece with a through structure of a nuclear station pressure container.

Description

technical field [0001] The invention relates to the technical field of cavitation water jet surface strengthening, in particular to a clamping device for a test of cavitation water jet surface strengthening treatment. Background technique [0002] The cavitation water jet surface strengthening technology uses the impact of the high-pressure bubble rupture generated in the high-speed water jet to generate a uniform compressive stress layer on the surface of the material. This technology can eliminate the residual tensile stress caused by welding, cold working, etc., and produce a surface layer with compressive stress, which can inhibit and delay the initiation of stress corrosion cracks on the surface of welded joints, thereby improving the resistance of materials to stress corrosion cracking and extending parts. service life. [0003] The pressure vessel of the nuclear power plant is designed with a through-tube structure. The through-tubes are arranged vertically. The wall...
