Description

Technical Field

[0001] The present application relates to the technical field of coating measurement, and in particular to a coating thickness gauge. Background Art

[0002] Coating thickness gauges are specialized devices used to measure the thickness of coatings or plating on a material's surface. In modern industry, coating thickness gauges are widely used in the automotive, aerospace, construction, and shipbuilding industries to precisely control coating quality. With technological advancements, coating thickness gauge design is constantly improving, with probe detachability becoming a key research topic.

[0003] Coating thickness gauges typically operate based on magnetic, eddy current, or ultrasonic principles. Magnetic thickness gauges are suitable for measuring non-magnetic coatings on ferromagnetic substrates, eddy current thickness gauges are suitable for measuring conductive coatings on non-ferromagnetic metal substrates, and ultrasonic thickness gauges are suitable for measuring the thickness of a variety of materials. These gauges transmit a signal through a probe and receive a reflected signal to calculate the coating thickness.

[0004] In existing coating thickness gauge designs, the probe is typically fixed to the instrument body and cannot be removed. This design means that if the probe is damaged or requires repair, the entire instrument must be returned to the manufacturer for repair, which is not only time-consuming but also expensive. Furthermore, due to the fixed connection between the probe and the instrument body, if the probe is damaged, it is often impossible to replace it individually; the entire probe assembly must be replaced, resulting in a waste of resources.

[0005] Therefore, it is necessary to design a structure to facilitate the disassembly of the probe of the coating thickness gauge. Utility Model Content

[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. It is understood that the drawings are only provided for reference and illustration purposes and are not used to limit the present application. The connection relationship shown in the drawings is only for the convenience of clear description and does not limit the connection method.

[0035] Specifically, if Figure 1 As shown, a coating thickness gauge is provided in an embodiment of the present application. The coating thickness gauge is mainly used to detect the thickness of the coating on the metal surface to determine whether the product is qualified. In this application, the structural details of the quick disassembly and rotation positioning of the coating thickness gauge are mainly protected. In view of this technical content, multiple embodiments are provided in this application to describe the structure.

[0036] First embodiment:

[0037] like Figure 1-Figure 2 As shown, the present application mainly comprises a main body 100, a rotating block 300 and a knob housing 200. The knob housing 200 is detachably connected to the main body 100. The knob housing 200 is rotatably connected to the main body 100, so that the knob housing 200 can be installed and removed from the main body 100. At the same time, a accommodating cavity 231 is opened in the knob housing 200, and the rotating block 300 is installed in the accommodating cavity 231. A probe 310 is provided on the rotating block 300, and the probe 310 can detect the coating thickness of the product.

[0038] In the above structure, since the knob housing 200 and the body 100 are rotatably connected, the probe 310 can be quickly and conveniently removed from and installed on the body 100 in the present application.

[0039] In the present application, the probe 310 on the rotating block 300 is set to be eccentric, so that when the rotating block 300 rotates, the probe 310 can detect the thickness of the coating at different positions.

[0040] The structure is mainly set up to accurately position the probe 310 and assist in the measurement of the coating. At the same time, in order to facilitate the rotation of the rotating block 300, limiting rings 320 can also be set on both sides of the rotating block 300. The radius of the limiting ring 320 is larger than the radius of the rotating block 300. A limiting groove 232 is opened in the accommodating cavity 231 corresponding to the position of the limiting ring 320. The limiting ring 320 is located in the limiting groove 232, so that the rotating block 300 can be confined in the accommodating cavity 231, thereby preventing the rotating block 300 from falling off from the accommodating cavity 231 due to the rotation of the rotating block 300.

[0041] Through the above structure, during detection, the probe 310 can be rotated to drive the rotating block 300 to rotate in the accommodating cavity 231, so as to bring the probe 310 to the corresponding position for coating detection.

[0042] In the above structure, the probe 310 is coated with a graphene layer 311 .

[0043] In the above structure, the knob housing 200 includes a rotating part 230 and a knob part 210. The knob part 210 is rotatably connected to the main body 100. The rotating part 230 is located on the knob part 210. The knob part 210 is provided with a rotating groove 212 corresponding to the position of the rotating part 230. The rotating part 230 is located in the rotating groove 212 and the rotating part 230 and the knob part 210 are disassembled and connected through threads. When the rotating part 230 is removed from the knob part 210, the rotating block 300 can be placed on the knob part 210 for installation, which is convenient for replacing the rotating block 300.

[0044] In the above structure, since the rotating block 300 is restricted in the accommodating cavity 231 by the limiting groove 232 , the detection range of the probe 310 is limited. Therefore, it is necessary to frequently replace the probe 310 with different positions to change the detection range of the probe 310 .

[0045] Second embodiment:

[0046] like Figure 2-3 As shown, an embodiment of the present application provides a coating thickness gauge, the overall structure of which is similar to that of the first embodiment, except that:

[0047] A motor 240 is also provided on the knob 210 , and the output end of the motor 240 is connected to the rotating block 300 , so that the rotating block 300 can rotate the probe 310 by rotating the motor 240 , and the rotating block 300 and the output end of the motor 240 are detachably connected.

[0048] Specifically:

[0049] In the second embodiment of the present application, and the structure that can be adapted to the conditions of other embodiments is that a fixing member 211 is provided on the knob member 210, and the fixing member 211 is located at a side opening of the accommodating cavity 231, so that the accommodating cavity 231 can be opened and closed, and an abutting member 213 is provided on the fixing member 211 at a side position facing the accommodating cavity 231. When the rotating member 230 is located in the accommodating cavity 231 and abuts against the limiting groove 232, the abutting member 213 abuts against the rotating block 300.

[0050] In the above structure, a through hole 214 is provided on the fixing member 211 corresponding to the output end of the motor 240, and the output end of the motor 240 is connected to the rotating block 300 through the through hole 214. An electric wire 250 is connected between the fixing member 211 and the rotating block 300, and the electric wire 250 is detachably connected to the fixing member 211 and the rotating block 300, so that the probe 310 is electrically connected.

[0051] In the above structure, a motor 240 is provided. To prevent the wire 250 from being torn due to the rotation of the motor 240, the motor 240 is configured as a servo motor in the embodiment of the present application, and the rotation angle of the output end of the motor 240 is preset to be less than or equal to 360 degrees.

[0052] Third embodiment:

[0053] like Figure 4-Figure 5 As shown, in the third embodiment of the present application, compared with the second embodiment, the motor 240 is cancelled, and an adjusting member 233 is provided on the rotating member 230. The adjusting member 233 is arranged at a position between the accommodating cavity 231 and the outside of the rotating member 230. The adjusting member 233 is connected to the rotating block 300 so that the adjusting member 233 adjusts the rotation angle of the rotating block 300.

[0054] In the embodiment of the present application, the adjusting member 233 is an adjusting gear, and the position corresponding to the adjusting gear on the rotating block 300 is set to a ring gear. When the rotating block 300 is set in the accommodating cavity 231, the abutting member 213 abuts against the rotating block 300, so that the adjusting member 233 is meshed with the ring gear on the rotating block 300, so that the rotating block 300 can be rotated and adjusted by the adjusting gear, thereby facilitating the adjustment of the position of the probe 310 on the rotating block 300.

[0055] Fourth embodiment:

[0056] like Figure 6-Figure 8As shown, in the embodiment of the present application, a rotation adjustment member 400 is further provided. The rotation adjustment member 400 divides the knob housing 200 into a knob member 210 and a knob base 220. The knob member 210 and the knob base 220 are adjusted and rotated by rotating the adjustment member 400.

[0057] The knob base 220 is detachably connected to the body 100 .

[0058] The rotating adjustment member 400 includes an adjustment ring 410, a rotating gear 411 is provided inside the adjustment ring 410, an adjustment slot 420 is provided on the knob member 210 corresponding to the rotating gear 411, and the rotating gear 411 is located in the adjustment slot 420. When the rotating gear 411 rotates, the knob member 210 is offset relative to the knob base 220.

[0059] The above structure can be applied to the structures in the first embodiment, the second embodiment, and the third embodiment without affecting the effects of other embodiments, so as to adjust the position of the probe 310 and avoid that some detection points cannot detect the coating thickness.

[0060] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
