Description

Technical Field

[0001] The utility model relates to the technical field of parts detection, and more specifically, to a device for detecting the bonding force of a coating layer of a precision part. Background Art

[0002] Adhesion testing is a key materials testing method used to assess the strength of the bond between a material or coating and its substrate. This testing is widely used in manufacturing, aerospace, automotive engineering, and other fields, and is crucial for ensuring product quality and reliability.

[0003] The existing method of destroying the coating layer on the surface of the substrate by applying strong pressure to the substrate instantly can only measure the critical value of the bonding between the coating and the substrate, but cannot measure the durability of the bonding between the substrate and the coating.

[0004] After searching, the Chinese patent with announcement number CN221280905U discloses a coating layer adhesion test device. By spraying sand and gravel onto the surface of the workpiece together with gas, the workpiece surface is continuously impacted to form a sandblasting-type coating layer adhesion durability test, changing the traditional instantaneous high-pressure detection method, and better detecting the durability of the base coating during actual use.

[0005] When the above-mentioned coating layer adhesion test device is actually used, the general clamping and fixing method adopts the left and right clamping method, which causes the precision parts to be subjected to uneven stress distribution in the clamping area, making it difficult to provide sufficient stability and clamping force, causing the sample to loosen or fall off during the test, thereby affecting the accuracy of the test results.

The relative movement of the three clamping plates 9 can clamp and fix the outside of the precision parts, so that the precision parts can remain relatively stable during the inspection process.

[0031] When the precision parts are fixed, the two cylinders 13 are started, and the two cylinders 13 push the protective ring 14 to slide inside the second slide groove 15. The two protective rings 14 can protect the outside of the chassis 11. Then the second motor 18 is started, and the threaded rod 19 is driven to rotate by the second motor 18, so that the threaded rod 19 drives the lower pressure plate 20 to move downward through the thread. The two third slide grooves 17 provide a guide for the movement of the lower pressure plate 20, so that the lower pressure plate 20 can drive the pressure head 22 downward to squeeze the parts.
