Description

Technical Field

[0001] This invention relates to the field of coating technology, specifically to a high-precision, high-efficiency coating insulation testing device. Background Technology

[0002] A coating is a covering applied to the surface of an object. The purpose of applying a coating can be for decoration, for function, or both. The coating itself can be a full coating that completely covers the substrate, or it can only cover a part of the substrate.

[0003] There are many methods for evaluating coatings, including destructive and non-destructive methods. In the insulating coating industry, testing its insulation is the most important step. However, existing insulation testing devices are inefficient and have poor accuracy, and can only roughly test the insulation performance under a fixed voltage. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] The purpose of this invention is to provide a high-precision and high-efficiency coating insulation testing device to solve the problems mentioned in the background art, such as the low working efficiency and poor accuracy of existing insulation testing devices, which can only roughly detect the insulation performance under a certain fixed voltage.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a high-precision, high-efficiency coating insulation testing device, comprising a support base, a display panel fixedly mounted on the front of the upper end of the support base, a support frame fixedly mounted on the upper end of the support base, a testing mechanism installed inside the support frame, a clamping mechanism fixedly mounted directly below the testing mechanism on the inner side of the support frame, the clamping mechanism comprising a clamping frame, a lower connecting piece fixedly mounted on the upper end of the clamping frame, a side connecting piece fixedly disposed on the inner end of the side of the clamping frame, the testing mechanism comprising a rear lower pressure rod and a front lower pressure rod, the rear lower pressure rod and the front lower pressure rod being symmetrically distributed on the upper end of the support frame, the lower ends of the rear lower pressure rod and the front lower pressure rod passing through the support frame and extending to the lower part of the support frame, a lower pressure plate fixedly connected to the lower ends of the rear lower pressure rod and the front lower pressure rod located below the support frame, a fixing sleeve rod fixedly connected to the lower end of the lower pressure plate, and the interior of the fixing sleeve rod... A spring is fixedly connected to the support frame. A push-out rod is fixedly connected to the lower end of the spring. The lower end of the push-out rod passes through a fixed sleeve and extends below it. A contact piece A is fixedly connected to the lower end of the push-out rod. A drive chamber is fixedly installed inside the upper part of the support frame. A front rack is fixedly installed inside the drive chamber at the inner end of the front downward pressure rod. A rear rack is fixedly installed inside the drive chamber at the inner end of the rear downward pressure rod. A damping knob is movably installed at the front end of the support frame. The rear end of the damping knob passes through the support frame and extends into the drive chamber. A drive gear is fixedly connected to the rear end of the damping knob inside the drive chamber. A first driven gear is meshed with the right end of the drive gear. The right end of the first driven gear meshes with the front rack. A reversing gear is meshed with the left end of the drive gear. A second driven gear is meshed with the left end of the reversing gear. The left end of the second driven gear meshes with the rear rack.

[0008] Preferably, a detection plate is installed at the inner end of the clamping mechanism. The detection plates are stacked and arranged at the inner end of the clamping mechanism. The side of the detection plate is attached to the side contact piece, and the bottom of the detection plate is attached to the bottom contact piece. During detection, an insulating coating can be applied to the upper end of the detection plate and the coating can be stably applied. The contact piece A is pressed down and tightly attached to the detection plate with the coating. Then, the display panel is operated to connect the contact piece A to the power supply. If the coating insulation effect is good, it is an open circuit. The display panel cannot receive the return power, and the indicator light on the display panel is green. If the coating insulation effect is poor, the display panel can receive the return power and make the indicator light red with different brightness according to the current.

[0009] Preferably, the electrical contact A is electrically connected to the display panel, the lower electrical contact is electrically connected to the display panel, and the side electrical contact is electrically connected to the display panel. This arrangement ensures that the detection circuit is unobstructed.

[0010] Preferably, multiple fixed sleeve rods are provided, and the fixed sleeve rods are arranged at equal intervals at the lower end of the lower pressure plate. By setting multiple sets of fixed sleeve rods arranged at equal intervals, insulating coatings of different thicknesses can be coated laterally on the upper end of the same detection plate, so that the ratio of the complete insulation of the same coating to its thickness can be detected simultaneously.

[0011] Preferably, an anti-slip pad is fixedly installed at the lower end of the support base, and the upper end of the anti-slip pad is in close contact with the lower end of the support base. The installed anti-slip pad can effectively improve the anti-slip performance of the detection device.

[0012] Preferably, the rear lower pressure rod and the front lower pressure rod have the same structure, and a limiting plate is fixedly provided at the upper end of the front lower pressure rod. The installed limiting plate can prevent the ends of the rear lower pressure rod and the front lower pressure rod from being submerged in the support frame and causing damage to the gears.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This high-precision and high-efficiency coating insulation testing device uses each testing plate as a testing carrier for only one coating. After use, it is recycled, making the testing of each coating more accurate and able to detect the relationship between the thickness of a coating and its insulation.

[0015] 2. This high-precision and high-efficiency coating insulation testing device, by setting up multiple sets of fixed sleeve rods arranged at equal intervals, can serve as multiple sets of experimental test controls, and can also test multiple different coatings at the same time, thereby effectively improving the working efficiency of the testing device.

[0016] 3. This high-precision, high-efficiency coating insulation testing device features an anti-slip pad that effectively improves its anti-slip properties, while the installed limit plate prevents the ends of the rear and front lower pressure rods from sinking into the support frame and damaging the gears.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-4This invention provides a technical solution: a high-precision, high-efficiency coating insulation testing device, comprising a support base 1, a display panel 2 fixedly mounted on the front of the upper end of the support base 1, a support frame 3 fixedly mounted on the upper end of the support base 1, a testing mechanism 4 installed inside the support frame 3, and a clamping mechanism 5 fixedly mounted below the testing mechanism 4 on the inner side of the support frame 3. The clamping mechanism 5 includes a clamping frame 501, a lower connecting plate 502 fixedly mounted on the upper end of the clamping frame 501, and a side connecting plate 503 fixedly mounted on the inner end of the side of the clamping frame 501. The testing mechanism 4 includes a rear lower pressure rod 401 and a front lower pressure rod 402, which are symmetrically distributed on the upper end of the support frame 3. The lower end of the pressure rod 402 passes through the support frame 3 and extends to the bottom of the support frame 3. The lower ends of the rear lower pressure rod 401 and the front lower pressure rod 402 are fixedly connected to a lower pressure plate 403 located below the support frame 3. The lower end of the lower pressure plate 403 is fixedly connected to a fixing sleeve rod 404. An ejector spring 405 is fixedly connected inside the fixing sleeve rod 404. An ejector rod 406 is fixedly connected to the lower end of the ejector spring 405. The lower end of the ejector rod 406 passes through the fixing sleeve rod 404 and extends to the bottom of the fixing sleeve rod 404. A contact piece A407 is fixedly connected to the lower end of the ejector rod 406. A drive chamber 408 is fixedly installed inside the upper part of the support frame 3. A front rack 409 is fixedly installed inside the drive chamber 408 at the inner end of the front lower pressure rod 402. The inner end of the rear lower pressure rod 401 is fixedly installed inside the drive chamber 408. A rear rack 410 is fixedly installed inside the drive compartment 408. A damping knob 411 is movably installed at the front end of the support frame 3. The rear end of the damping knob 411 passes through the support frame 3 and extends into the drive compartment 408. A drive gear 412 is fixedly connected to the rear end of the damping knob 411 inside the drive compartment 408. A first driven gear 413 is meshed with the right end of the drive gear 412. The right end of the first driven gear 413 is meshed with the front rack 409. A reversing gear 414 is meshed with the left end of the drive gear 412. A second driven gear 415 is meshed with the left end of the reversing gear 414. The left end of the second driven gear 415 is meshed with the rear rack 410. A detection plate 6 is installed inside the clamping mechanism 5. The detector plate 6 is stacked inside the clamping mechanism 5. The sides of the detector plate 6 are in contact with the side contact plate 503, and the bottom of the detector plate 6 is in contact with the lower contact plate 502. During testing, an insulating coating can be applied to the upper end of the detector plate 6 and the coating can be stably applied. Then, by manually rotating the damping knob 411, the lower pressure plate 403 and the contact plate A407 can be raised together under the linkage of the driving gear 412, the first driven gear 413, the reversing gear 414, the second driven gear 415, the front rack 409, and the rear rack 410. The raised position can be maintained under the action of the damping knob 411. Then, the detector plate 6 is placed inside the clamping mechanism 5, and then the damping knob 411 is manually rotated again to press down the contact plate A407 and make it stick tightly to the coated detector plate 6.Then, by manipulating display panel 2 to connect the contact plate A407, if the coating insulation effect is good, it indicates an open circuit, and display panel 2 cannot receive the return power, so the indicator light on display panel 2 will display green. If the coating insulation effect is poor, display panel 2 can receive the return power, and the indicator light will display different brightness levels of red depending on the current magnitude. Simultaneously, the magnitude of the return current can be displayed on display panel 2, thus greatly improving the detection accuracy of the device.

[0024] Electrically connected contact A407, lower contact 502, and side contact 503 are all electrically connected to the display panel 2. This arrangement ensures a smooth detection circuit. Fixed sleeves 404 are equidistantly arranged at the lower end of the lower pressure plate 403. By setting multiple sets of equidistantly arranged fixed sleeves 404, insulating coatings of different thicknesses can be applied laterally to the upper end of the same detection plate 6. This allows for simultaneous testing of the ratio of the complete insulation performance of the same coating to its thickness, and also serves as a basis for multiple sets of experiments. The detection comparison effectively improves the working efficiency of the detection device. The lower end of the support base 1 is fixedly installed with an anti-slip pad 7, and the upper end of the anti-slip pad 7 is tightly fitted with the lower end of the support base 1. The installed anti-slip pad 7 can effectively improve the anti-slip performance of the detection device. The rear lower pressure rod 401 and the front lower pressure rod 402 have the same structure. The upper end of the front lower pressure rod 402 is fixedly provided with a limit plate 8. The installed limit plate 8 can prevent the ends of the rear lower pressure rod 401 and the front lower pressure rod 402 from sinking into the support frame 3 and causing damage to the gears.

[0025] Working principle: During testing, an insulating coating is applied to the upper end of the test plate 6 and the coating is stabilized. Then, by manually rotating the damping knob 411, the lower pressure plate 403, along with the contact piece A407, is raised together under the linkage of the driving gear 412, the first driven gear 413, the reversing gear 414, the second driven gear 415, the front rack 409, and the rear rack 410. The raised position is maintained by the damping knob 411. Then, the test plate 6 is placed inside the clamping mechanism 5. Then, by manually rotating the damping knob 411 again, the contact piece A407 is pressed down and pressed tightly against the coated test plate 6. The display is then controlled. Panel 2 connects the contact piece A407 to power. If the coating insulation effect is good, it indicates an open circuit, and the display panel 2 cannot receive the return power. The indicator light on the display panel 2 will show green. If the coating insulation effect is poor, the display panel 2 can receive the return power and the indicator light will show different brightness red according to the current magnitude. At the same time, the magnitude of the return current can be displayed on the display panel 2. By setting multiple sets of fixed sleeve rods 404 arranged at equal intervals, insulating coatings of different thicknesses can be coated laterally on the upper end of the same detection plate 6. The ratio of the complete insulation of the same coating to its thickness can be detected simultaneously. It can also be used as a control for multiple sets of experimental tests.

[0026] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, and is not intended to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention do not depart from the essence and scope of the technical solution of the present invention.
