Problems solved by technology

However, due to manual adjustment, it is inevitable that it will not be timely, not in place, uneven force and local stress concentration, etc., so the quality of test data is difficult to guarantee
There is no existing detection device that can automatically complete the bending strength test of the fine ceramic bonding interface without manual adjustment for samples with uneven, non-parallel or curved surfaces.

Embodiment 1

[0023] Example 1, as Figure 1 to Figure 6 As shown, this embodiment provides the specific structure and working process of the automatic testing device for the bending strength of the fine ceramic bonding interface.

[0024] The device frame is composed of four vertical emptying square tubes 1, two lower horizontal long emptying square tubes 2, two upper long horizontal emptying square tubes 25, two upper short horizontal emptying square tubes 24 and two lower short horizontal emptying square tubes 52 welded together . The fine ceramic bonding interface bending strength sample 39 is placed on two support rollers, the distance between the two support rollers is less than the length of the sample 39, the outer diameter of the two support rollers is the same, and the centerlines of the two axes are parallel in the same horizontal plane. The length direction of the sample 39 is perpendicular to the centerline of the axes of the two support rollers and is located in the middle of...

Abstract

The invention belongs to the technical field of ceramic detection devices, and relates to an automatic testing device for the bending strength of a fine ceramic bonding interface. The device solves the problem that the surface of the sample is not flat, parallel or curved in the process of testing the bending strength of the fine ceramic bonding interface The test process is automated to improve the test quality and efficiency.

Description

technical field [0001] The invention belongs to the technical field of ceramic detection devices, and relates to an automatic testing device for the bending strength of a fine ceramic bonding interface. Background technique [0002] Fine ceramics are also known as high-performance or high-tech ceramics. Their unique high strength, high hardness, corrosion resistance, electrical conductivity, insulation and special properties in magnetic, electrical, optical, acoustic, and biological engineering make them suitable for high temperature, mechanical , electronics, aerospace, medicine and other fields are widely used. In order to achieve the required performance in actual use, after bonding ceramics with ceramics, ceramics and metals by a specific process, it is necessary to detect whether the flexural strength of the bonding interface at room temperature meets the requirements of material development, quality control, characterization and generative design. data, etc. Therefor...
