Description

Technical Field

[0001] The present invention relates to the technical field of thickness testers, in particular to an engineering material thickness tester. Background Art

[0002] The engineering material thickness tester is a professional tool used to measure the thickness of metals, plastics, composite materials, etc. It is widely used in fields such as construction, shipbuilding, pipelines, and machinery manufacturing. Its precise measurement capability is crucial to ensuring the safety and integrity of structures. Most existing equipment adopts a fixed integrated structural design. Although it has the advantages of good integrity and high stability, it still has obvious defects: First, the support base and detection components cannot be modularly disassembled and assembled, resulting in difficulties in maintenance and replacement, reducing the flexibility and maintenance efficiency of the equipment; second, the support base lacks an adjustable limit clamping function, which has operational limitations when detecting materials of different sizes, affecting the scope of use. These design defects restrict the adaptability of the equipment in complex engineering environments, and it is urgent to improve its functionality through structural optimization.

[0003] To solve the above problems, the patent document with authorization publication number CN222635441U in the prior art provides a thickness tester for engineering materials; this device provides great convenience for the engineering site through its adjustable characteristics.

[0029] The specific working principle and method of use of the present invention are explained in detail below: Before the thickness test, the material is placed between the second guide wheel 14 and the first guide wheel 13, and the drive motor 28 is started to rotate the threaded rod 27 through its output shaft. The limiting slide 26 is connected to the threaded plate 25 through the sliding connection between the limiting slide 26 and the threaded plate 25, which restricts the movement direction of the first push-out plate 23. The rotating threaded rod 27 can drive the first push-out plates 23 on both sides to move toward each other, so that the distance between the first guide wheels 13 on both sides and the distance between the second guide wheels 14 on both sides match the width of the material.

[0030] Then, the cylinder 22 is started, and the second push plate 24 and the second side plate 21 are driven downward by the output shaft thereof, so that the second guide wheel 14 and the first guide wheel 13 are respectively fitted with the upper and lower ends of the material, thereby achieving the effect of positioning the material.

[0031] During the downward movement of the second guide wheel 14, the spring 44 recovers its deformation and drives the first movable plate 4 and the second movable plate 41 to move outward through the plug-in connection between the movable rod 43 and the limit plate 42, thereby driving the first tensioning shaft 35 and the second tensioning shaft 34 to move outward, ensuring that the transmission belt 36 is always in a taut state.

[0032] When the material thickness needs to be tested, the dual-axis motor 3 is started, and the drive shaft 30 is driven to rotate through its output shaft. The first driven shaft 31 and the second driven shaft 32 can be driven to rotate in opposite directions through the transmission belt 36, the auxiliary shaft 33, the first tensioning shaft 35 and the second tensioning shaft 34. Cooperating with the first guide wheel 13 and the second guide wheel 14, the material is guided, and the ultrasonic thickness gauge 11 and the ultrasonic probe 12 are started. The ultrasonic probe 12 emits ultrasonic waves, and the feedback sound wave information is collected, and the data is transmitted to the ultrasonic thickness gauge 11. The information can be organized and displayed through the ultrasonic thickness gauge 11.

[0033] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are common means well known to those skilled in the art.
