Description

Technical Field

[0001] This utility model relates to the field of coating testing technology, specifically to a carbon gradient coating film adhesion testing device. Background Technology

[0002] Carbon gradient coatings, due to their unique composition and structural gradients, have wide applications in aerospace, machinery manufacturing, and electronic devices. Coating adhesion is a key performance indicator for measuring coating quality, directly affecting the coating's service life and reliability.

[0003] The traditional method for testing coating adhesion is the cross-cut test. During the test, the knife is held and several horizontal and vertical scratches are made on the part to form a vertical grid. Finally, tape is applied to the grid and then quickly peeled off to observe the coating condition on the grid. However, when using the hand-cut grid method, the scratches are prone to bending, which leads to inaccurate test results. Utility Model Content

[0013] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0014] See attached diagram. Figures 1 to 2 The carbon gradient coating film adhesion testing device in this embodiment includes a base 1, a placement platform 2 on the base 1, an annular plate 3 rotatably mounted on the outer periphery of the placement platform 2, a support rod 31 on the annular plate 3, an mounting plate 4 on the support rod 31, and a grid-marking mechanism on the mounting plate 4; a first motor 10 is provided on the base 1, and a drive gear 11 is provided at the output end of the first motor 10.

[0015] In one possible implementation, the height of the support rod 31 can be adjusted to suit testing requirements.

[0016] Furthermore, the outer ring of the annular plate 3 is provided with several external teeth 30, which mesh with the drive gear 11 for transmission, and the annular plate 3 and the placement platform 2 can rotate relative to each other.

[0017] Furthermore, the dividing mechanism includes a second motor 40, the output end of which is provided with a turntable 7, the turntable 7 is provided with a cylindrical pin 70, an arc-shaped rod 8 is hinged to the mounting plate 4, an arc-shaped groove 80 is opened on the arc-shaped rod 8, and the cylindrical pin 70 is slidably connected to the arc-shaped groove 8; a first connecting seat 81 is hinged to the bottom end of the arc-shaped groove 8, a second connecting seat 82 is hinged to one end of the first connecting seat 81, a slider 6 is provided at the bottom of the second connecting seat 82, a sliding plate 60 is provided at the bottom of the slider 6, and a dividing cutter 61 is provided at the bottom of the sliding plate 60.

[0018] Furthermore, the cylindrical pin 70 is eccentrically positioned on the turntable 7.

[0021] Working principle: During testing, the test piece is placed on the placement platform 2 and clamped and fixed by the clamping device. The height is adjusted by the support rod 31 so that the scribing cutter 61 abuts against the test piece. Then, the second motor 40 is started, which drives the turntable 7 to rotate, thereby causing the cylindrical pin 70 to slide in the arc groove 80 of the arc rod 8. Under the guidance of the curved arc groove 80, one end of the arc rod 8, together with the first connecting seat 81 and the second connecting seat 82, drives the slider 6 to slide in the sliding groove 50, thereby causing the slide plate 60 and the scribing cutter 61 to slide and make transverse scratches on the test piece. Then, the first motor 10 is started, which drives the drive gear 11 to rotate. The drive gear 11 drives the ring plate 3 to rotate, causing the scribing mechanism to change direction. The above operation is repeated to make longitudinal scratches on the test piece.
