Embodiment 1

[0038] Hereinafter, this embodiment will be described in detail with reference to Figs. 1, Figs. 2-1, 2-2, and 2-3.

[0039]The detection device of the present invention consists of a supporting rod 1, a top cover 2, a screw 3, a limit sleeve 4, a PLC temperature control heating jacket 5, a clamp-shaped indenter 6, an internal thread core 7, a bulk amorphous alloy 8, a top The rod 9, the base 10, the temperature measurement blind hole 11, the limit insert 12, the detection element 13 and the connecting rod 14. The detection element 13 adopts a high-power optical microscope, and the support rod 1 is connected to the high-power optical microscope through the connecting rod 14 , Used for rotating positioning observation. The lower end of the top cover 2 is connected with the screw 3 for applying the output displacement. The neck of the screw 3 is provided with a limiting sleeve 4 to avoid damage to the clamp-shaped indenter 6 and the internal thread core 7 due to excessive stroke. Th...

Embodiment 2

[0049] Hereinafter, this embodiment will be described in detail with reference to Fig. 1 and Figs. 3-1, 3-2, and 3-3.

[0050] The detection device is different from Embodiment 1 in that: the detection element 13 is a high-resolution camera.

Abstract

A nondestructive detection method of internal thread core on precise tube includes selecting proper size of large block amorphous alloy, placing internal thread core in temperature controlled heating jacket by pincer like head and starting up heating, setting blank of said amorphous alloy in groove of base and leading inert gas in, using screw to drive pincer like head to let said core contact with said blank for carrying out replication, unloading and taking out large block amorphous alloy for cooling. The device used for realizing said method is also disclosed.

Description

Technical field: [0001] The invention relates to the technical field of testing precision internal thread pipe molds, in particular to a non-destructive testing method and detection device for the internal thread core head of the precision pipe, and is particularly suitable for the non-destructive testing of the internal thread core head tooth profile of the fine-diameter seamless precision copper pipe Detection. Background technique: [0002] Nowadays, the destruction of the ozone layer has become one of the global environmental issues of concern to all countries, and an international unified action to protect the ozone layer has been formed, stepping up the elimination of ozone-depleting substances on a global scale. According to the Montreal Protocol on Substances Destroying the Ozone Layer passed in 1987, the use of CFC refrigerants has been restricted since July 1980. At the Copenhagen Conference in 1992, it was decided to abolish the use of CFCs and restrict the production ...
