Description

Technical Field

[0001] This utility model relates to the field of ultrasonic testing technology, and more specifically, to an ultrasonic coating thickness measuring instrument. Background Technology

[0002] An ultrasonic thickness gauge is an instrument that determines the thickness of a material by accurately measuring the propagation time of ultrasonic waves through the material based on the reflection of emitted pulses back to the probe. In automotive production and inspection, ultrasonic gauges are used to detect the thickness of plating layers on automotive workpieces. For example, patent CN219573004U discloses an automotive electroplating thickness gauge. Pulling the adjustment plate and then rotating the storage plate causes the protective plate to rotate. When the desired angle is reached, releasing the adjustment plate allows it to engage a gear with a limiting groove, fixing the angle of the storage plate. The protective plate then protects the main body of the gauge. During testing, pressing the detection head allows it to move within the positioning shell, improving the stability and accuracy of the detection head.

[0003] When the above-mentioned device is in use, the design of fixing one end of the second spring to one end of the storage slot allows the connecting plate and the storage plate to be elastic. When the protective plate is impacted, the second spring can reduce the impact on the connecting plate, thereby effectively protecting the main body of the detector. However, the detection head needs to be flush with the protective plate fixing sleeve. When a collision occurs, the surface of the detection head is more easily damaged, and the accuracy of the ultrasonic detection device in detecting the coating on the surface of automotive workpieces is easily affected. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an ultrasonic coating thickness detector. The technical problem to be solved by the present invention is: how to increase the protective effect of the detection head and avoid damage to the surface of the detection head.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an ultrasonic coating thickness detector, comprising a detector body, a fixed connector on one side of the upper end of the detector body, a connecting wire at one end of the fixed connector, a detection head at one end of the connecting wire, a detection shell at the outer end of the detection head, and a support slider at the outer end face of the connection between the detection head and the connecting wire. The outer end face of the support slider is provided with multiple concave grooves, one side of the inner end face of the detection housing is provided with a limiting protrusion, the inner end face of the detection housing is provided with multiple convex sliders on one side of the limiting protrusion, the inner end face of the limiting protrusion is provided with multiple fixing protrusions, and the outer end face of the connection between the support slider and the connecting wire is provided with a support spring.

[0006] In a preferred embodiment, the upper end of the detector body is provided with a display screen and control buttons, and one end of the detector housing is provided with a concave fixing groove.

[0007] In a preferred embodiment, an annular sealing gasket is provided on the outside of one end of the detection housing, and a convex fixing block is provided on one side of the outer end face of the annular sealing gasket.

[0008] In a preferred embodiment, one end of the detector body is provided with an annular fixing groove, and an annular fixing cylinder is provided inside the annular fixing groove.

[0009] In a preferred embodiment, a support telescopic rod is provided on one side of the inner end face of the annular fixed cylinder, and a return spring is provided on the outer end face of the support telescopic rod.

[0010] In a preferred embodiment, one end of the support telescopic rod is provided with a rubber top plate, and two locking grooves are provided on the outer side of one end of the annular fixed cylinder.

[0011] In a preferred embodiment, the outer end face of the support slider is in contact with the inner end face of the detection housing, and the inner end face of the concave groove is in contact with the outer end face of the convex slider. The diameter of the inner end face of the limiting protrusion in the right-viewing direction is smaller than the diameter of the inner end face of the detection housing in the right-viewing direction.

[0012] In a preferred embodiment, the outer end face of the fixing protrusion is in contact with the inner end face of the locking groove, and the inner end face of the concave fixing groove is in contact with the outer end face of the convex fixing block. The annular sealing gasket is a rubber component, and the inner end face diameter of the concave fixing groove is larger than the outer end face diameter of the detection housing.

[0013] In a preferred embodiment, the inner end face of the annular fixed cylinder is larger than the outer end face of the detection head, and the outer end face of the rubber top plate is in contact with the inner end face of the annular fixed cylinder.

[0014] The technical effects and advantages of this utility model are as follows: In practical use, this invention, with the corresponding arrangement of the convex slider, support spring, support slider, concave groove, and annular sealing gasket, allows for the detection of the coating on the surface of an automotive workpiece. The detection head is placed against the surface of the workpiece, and the detection housing is pressed down, causing the annular sealing gasket to adhere to the surface. The detection head then pushes against the support slider, retracting into the detection housing. The support spring also pushes against the support slider, ensuring the detection head is stably attached to the surface of the automotive workpiece. This results in more accurate detection of the coating on the automotive workpiece surface.

[0015] Simultaneously, with the corresponding settings of the annular fixing cylinder, rubber top plate, support telescopic rod, return spring, and locking groove, when storing the detection housing and detection head, they can be inserted into the annular fixing groove and annular fixing cylinder. The detection head will fit against the end face of the rubber top plate, causing the fixing protrusion to be locked inside the locking groove and rotate. The elastic force generated by the support spring and return spring will stably fix the detection housing and detection head inside the annular fixing groove, making the storage and fixing of the detection head and detection housing more convenient and stable, thus effectively protecting the detection head and preventing damage to the contact surface of the detection head.
