Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic detection, and in particular to a portable spheroidization rate detector. Background Art

[0002] The spheroidization rate is the percentage of spheroidal graphite in the total graphite. It is an important indicator to measure the graphite morphology in cast iron. Specifically, it is a comprehensive indicator of the spheroidization degree of all graphite in the specified field of view. The spheroidization rate is crucial to evaluate the mechanical properties of cast iron, because the presence of spheroidal graphite can significantly improve the strength, toughness and fatigue resistance of cast iron. The mechanical properties of ductile cast iron are largely determined by the spheroidization rate. Generally speaking, under the same other conditions, the higher the spheroidization rate, the higher the mechanical properties.

[0003] Therefore, testing the spheroidization rate of materials is not only an important indicator for evaluating the performance of cast iron, but also an important research object that cannot be ignored in the field of materials science. By testing and effectively controlling the spheroidization rate, we can better meet the needs of engineering applications and improve product quality and reliability.

[0004] Currently, the equipment for detecting spheroidization rate on the market is too large and not portable enough. For detecting small objects, the steps are cumbersome and the adaptability is poor. Summary of the invention

[0005] The problem to be solved by the present invention is to design a portable spheroidization rate detector to solve the problem that the equipment for detecting spheroidization rate on the current market is too large and not portable enough.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a portable spheroidization rate detector, mainly comprising a handle 1, a static probe frame 14, a sliding probe frame 11, a spheroidization rate probe, and a push button 5. The static probe frame 14 is fixedly connected to one end of the handle and fixed relative to the handle, and the sliding probe frame 11 is movable relative to the handle. The sliding probe frame 11 can move up and down by pushing the push button 5. The static probe frame 14 and the sliding probe frame 11 are used to form a clamping mechanism to clamp and fix the object to be tested. It is suitable for a variety of workpieces and can better fix the material to be tested, so that the result is more accurate. Both the static probe frame 14 and the sliding probe frame 11 fix the spheroidization rate probe, and can carry out detection on the object to be tested.

[0007] A capacitive scale 3 is mounted on one side of the handle 1, which can measure the distance moved by the sliding probe frame 11 and then measure the size of the object being detected.

[0008] A hand grip 13 is provided at the lower end of one side of the handle 1, which is beneficial to improving the stability and comfort of holding the hand. A hole groove is opened at the bottom of the hand grip to allow the cable to enter.

[0009] The handle 1 has a groove inside the handle, leaving space for the sliding probe frame to move, and an upper cover 2 is installed on one side, and a winder 6 is installed below the upper cover 2. The winder can be set to manually drive the winding; a rebound spring can also be set inside, and the cable can automatically extend or rewind the winder 5. The upper cover can properly seal the wire inside. A hole is opened between the upper cover 2 and the hand-held grip 13 to allow the wire to enter. The cable can enter the winder 6 through the round hole, which is convenient for adjusting the cable length. The cable extends or shortens as the sliding probe frame 11 moves.

[0010] The handle 1 is provided with probe cover baffles 4 on both sides, which can lock the sliding probe frame on the handle to allow the sliding probe frame to move stably in translation. A push button 5 is provided on one side of the probe cover baffle 4, which is conducive to comfortable and quick movement of the sliding probe frame.

[0011] The sliding probe frame 11 is provided with a long probe fixing frame 10 inside, a spheroidization rate probe 12 is provided below the long probe fixing frame 10, and the upper part of the long probe fixing frame 10 is connected to the liquid immersion chamber cover 9 via the liquid immersion chamber adapter 8; the static probe frame 14 is provided with a short probe fixing frame 7 inside, a spheroidization rate probe 12 is provided above the short probe fixing frame 7, and the lower part of the short probe fixing frame 7 is connected to the liquid immersion chamber cover 9 via the liquid immersion chamber adapter 8. Because the spheroidization rate probes have different powers, types, sizes, etc., different probe fixing frames can be installed on the handle. Through the long probe fixing frame 10 and the short probe fixing frame 7, one probe fixing frame can be adapted to different spheroidization rate probes 12. It is only necessary to replace the probe fixing frame or the spheroidization rate probe as needed, thereby improving the utilization rate and adaptability of the portable spheroidization rate detector.

[0012] The liquid immersion chamber adapter 8 and the liquid immersion chamber cover 9 form a closed space in which liquid is placed. The probe directly detects the object through the liquid. The front end of the liquid immersion chamber adapter 9 adopts soft film packaging, which is conducive to close fitting with the object to be detected, thereby improving the detection accuracy of the object.

[0013] A portable spheroidization rate detector comprises a handle, a static probe rack, a sliding probe rack, a spheroidization rate probe, and a push button. Through the double-sided clamping mechanism of the static probe rack and the sliding probe rack, a high-power spheroidization rate probe is adopted, and the spheroidization rate detection of various workpieces can be adapted. The front end of the liquid immersion chamber adopts soft film packaging, which is not afraid of the rough workpiece surface, ensures the stability of the fit and the accuracy of the detection result, and has the remarkable characteristics of small size, easy use, and high measurement accuracy.
