Description

Technical Field

[0001] This invention relates to the field of ultrasonic testing technology, and in particular to a portable sphericity testing device. Background Technology

[0002] The spheroidization rate, or the percentage of spheroidal graphite in the total graphite, is an important indicator for measuring the graphite morphology in cast iron. Specifically, it is a comprehensive indicator of the degree of spheroidization of all graphite within a specified field of view. The spheroidization rate is crucial for evaluating the mechanical properties of cast iron because the presence of spheroidal graphite significantly improves the strength, toughness, and fatigue resistance of cast iron. The mechanical properties of ductile iron are largely determined by the spheroidization rate; generally, under the same conditions, a higher spheroidization rate results in higher mechanical properties.

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

[0004] Currently available equipment for detecting sphericity is too bulky and not portable enough. For detecting small objects, the process is cumbersome and the equipment is not very adaptable. Summary of the Invention

[0005] The problem this invention aims to solve is: to design a portable sphericity rate detector to address the issue that current market devices for detecting sphericity rate are too large and not portable enough.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a portable sphericity rate detector, mainly comprising a handle 1, a stationary probe holder 14, a sliding probe holder 11, a sphericity rate probe, and a push button 5. The stationary probe holder 14 is fixedly connected to one end of the handle and is fixed relative to the handle. The sliding probe holder 11 is movable relative to the handle, and the sliding probe holder 11 can move up and down via the push button 5. The stationary probe holder 14 and the sliding probe holder 11 form a clamping mechanism to clamp and fix the object being tested, adapting to various workpieces and better fixing the measured material, resulting in more accurate results. Both the stationary probe holder 14 and the sliding probe holder 11 fix the sphericity rate probe, enabling the detection of the object being tested.

[0007] The handle 1 is equipped with a grating ruler 3 on one side, which can measure the distance the sliding probe frame 11 moves, and then measure the size of the object being detected.

[0008] The lower end of one side of the handle 1 is equipped with a hand grip 13, which helps to improve the stability and comfort of holding the hand. The bottom of the hand grip has a slot to allow the cable to enter.

[0009] The handle 1 has a groove inside to allow space for the sliding probe holder to move. A top cover 2 is mounted on one side, and a cable winder 6 is mounted below the top cover 2. The cable winder can be manually driven for winding; alternatively, it can have an internal spring so the cable can automatically extend or rewind back into the winder 5. The top cover can appropriately enclose the internal cable. A hole is formed between the top cover 2 and the hand grip 13 to allow the cable to enter. The cable passes through a circular hole into the cable winder 6, facilitating cable length adjustment. The cable extends or shortens as the sliding probe holder 11 moves.

[0010] The handle 1 is equipped with probe sleeve baffles 4 on both sides, which can lock the sliding probe frame on the handle and allow the sliding probe frame to move horizontally and stably. The probe sleeve baffle 4 is equipped with a push button 5 on one side, which facilitates comfortable and quick movement of the sliding probe frame.

[0011] The sliding probe holder 11 houses a long probe mounting bracket 10, with a spheroidization rate probe 12 mounted below it. The long probe mounting bracket 10 is connected to the liquid immersion chamber cover 9 via a liquid immersion chamber adapter 8. The stationary probe holder 14 houses a short probe mounting bracket 7, with the spheroidization rate probe 12 mounted above it. The short probe mounting bracket 7 is connected to the liquid immersion chamber cover 9 via a liquid immersion chamber adapter 8. Because the spheroidization rate probes differ in power, type, and size, different probe mounting brackets can be installed on the handle. The long probe mounting bracket 10 and the short probe mounting bracket 7 allow one probe mounting bracket to accommodate different spheroidization rate probes 12; simply replace the probe mounting bracket or the spheroidization rate probe as needed, improving the usability and adaptability of the portable spheroidization rate detector.

[0012] The liquid immersion chamber adapter 8 and the liquid immersion chamber cover 9 form a sealed space containing liquid. The probe directly detects the object through the liquid. The front end of the liquid immersion chamber adapter 8 is encapsulated with a soft film, which facilitates close contact with the object being tested and improves the detection accuracy of the object.

[0013] A portable sphericity tester includes a handle, a stationary probe holder, a sliding probe holder, a sphericity probe, and a push button. It features a double-sided clamping mechanism using the stationary and sliding probe holders, employs a high-power sphericity probe, and can adapt to the sphericity testing of various workpieces. The front end of the liquid immersion chamber is encapsulated with a soft film, making it resistant to rough workpiece surfaces, ensuring stable adhesion and accurate test results. It is characterized by its compact size, ease of use, and high measurement accuracy. Attached Figure Description
