Description

Technical Field

[0001] This utility model relates to the field of coating testing equipment technology, and in particular to an automatic coating scratch testing device. Background Technology

[0002] Coating adhesion is an important indicator for evaluating coating quality. The scratch test is a common method for testing coating adhesion, which requires a paint scratch tester.

[0003] For example, Chinese Patent CN221960004U discloses a coating adhesion tester, including an operating table. The top of the operating table has an adjusting component, which includes a vertical rod. A first groove is vertically slidably opened through the top surface of the operating table. The vertical rod is slidably installed inside the first groove. A horizontal plate is horizontally fixedly connected to the top of the vertical rod. A second groove is horizontally slidably opened inside the horizontal plate. An I-shaped slider is slidably installed inside the second groove. A handle is fixedly connected to the left end of the I-shaped slider. This device allows adjustment of the distance between the left and right pressure plates by rotating a handwheel to match coating plates of different lengths. Furthermore, the distance between the front and rear pressure plates can be adjusted by sliding the I-shaped slider back and forth inside the second groove, thus adapting to coating plates of different widths. However, the position of the testing component is fixed. When testing different positions of the coating plate, the coating plate needs to be repeatedly moved, making it inconvenient to use.

One end of the elastic element 24 is mounted on the carrier plate 21, and the other end is mounted on one end of the clamping block 22. Optionally, the support portion 221 is slidably mounted on the guide rails 23, and one end of the elastic element 24 is mounted on one end of the support portion 221. Further, the sliding groove 210 is used to accommodate the guide rails 23, clamping blocks 22, and elastic elements 24, with each sliding groove 210 corresponding to one clamping block 22. The elastic element 24 is a spring. In one embodiment, there are three sliding grooves 210, clamping blocks 22, guide rails 23, and elastic elements 24.

[0026] like Figure 1 As shown, the test assembly 30 includes a base 31, a slide 32, a support arm 33, a rotational power element 34, a turntable 35, a scribing needle 36, and a pressing power element 37. The base 31 is mounted on the machine tool 10, the slide 32 slides on the base 31, one end of the support arm 33 is mounted on the slide 32, and the rotational power element 34 is mounted on the end of the support arm 33 away from the slide 32. The rotational power element 34 drives the turntable 35 to rotate. The scribing needle 36 is eccentrically mounted on the turntable 35 and abuts against the paint plate. The scribing needle 36 scrapes the paint plate as the turntable 35 rotates. Optionally, the scribing needle 36 is detachably connected to the turntable 35 for replacement. The pressing power element 37 is mounted on the support arm 33, and the output end of the pressing power element 37 is connected to the rotational power element 34.

Optionally, there are two guide rods 38; further, the telescopic power element 39 is a lead screw motor; the position of the scriber 36 is adjusted by driving the slide block 32 to slide via the telescopic power element 39.

[0028] In use, the edge of the paint plate is pressed down along the inclined surface of the guide portion 222 until the edge of the paint plate is accommodated in the groove 223; alternatively, one of the clamping blocks 22 is stretched outward, and the paint plate is placed on the carrier plate 21 and the other two support portions 221. The stretched clamping block 22 is then released, and under the rebound action of the elastic element 24, the three clamping blocks 22 cooperate to clamp the paint plate, with the edge of the paint plate accommodated in the groove 223. Next, the rotating power element 34 drives the turntable 35 to rotate, and the turntable 35 drives the scribing needle 36 to rotate, causing the scribing needle 36 to scrape the paint plate. Simultaneously, the downward pressing power element 37 drives the rotating power element 34 to descend, thereby applying pressure to the paint plate by the scribing needle 36. The pressure value of the downward pressing power element 37 is recorded to determine the adhesion of the paint plate. When testing different positions, the telescopic power element 39 drives the slide 32 to slide, thereby adjusting the position of the scribing needle 36 relative to the paint plate, eliminating the need to adjust the position of the paint plate, making it convenient to use.

[0029] The automatic paint scratch testing device 100 of this utility model uses a clamping block 22 to hold the paint plate, and a scratching needle 36 scrapes the paint plate as the turntable 35 rotates. At the same time, a downward pressing power element 37 causes the scratching needle 36 to apply pressure to the paint plate. The device is slidably mounted on the base 31 via a sliding seat 32, thereby adjusting the position of the scratching needle 36 to facilitate testing different positions of the paint plate.

[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
