Embodiment 1

[0016] According to the requirements of "GB / T6569-2006 Fine Ceramic Bending Strength Test Method", the size requirements of the four-point bending strength test sample are: width 4±0.2mm, height 3±0.2mm, length ≥ 45mm, using this fixture to meet the standard The required sample procedure is as follows: Process the ceramic sample to be connected into a 3mm×4mm×25mm strip sample. The width of the longitudinal groove in the fixture is designed to be 3.1mm, the depth is designed to be 3.5mm, the width of the transverse groove is 20mm, and the main body size is 120mm (length) × 48mm (width) × 15mm (thickness), the size of the side plate is 120mm × 48mm × 5mm, the size of the bottom plate is 120mm × 20mm × 5mm, and the thickness of the counterweight plate is calculated according to the required pressure. The principle of fixture use is as follows: figure 2 As shown, firstly, the bottom plate and the grounded two surfaces of the main body are fixed with bolts, and the sample 7 is pu...

Abstract

The invention relates to a clamp used for preparing the connector standard bending strength test samples, belonging to the connector bending-strength test field. The invention comprises four parts: a main body, a side plate, a soleplate and a counterweight plate which are connected into an integrity through bolts. A group of parallel ']' shaped groove and one horizontal groove are processed in the main body; the size and shape precision of the connector samples can be guaranteed through the alignment effect of the ']' shaped groove and the horizontal groove is used for clamping the samples and prevent the welding material from adhereing to the clamp. Additionally, the counterweight plate can guarantee the pressure required by the process. The invention can prepare a plurality of test samples by one time.

Description

technical field [0001] The invention relates to a fixture used for preparing standard bending strength test samples of connectors, belonging to the field of bending strength tests of connectors. Background technique [0002] In recent years, the connection technology of materials has developed rapidly, and different connection processes have realized the connection of similar materials and dissimilar materials, especially the connection between ceramics and ceramics and the connection between ceramics and metals. Requirements, the strength index of the connector must be evaluated. There are three methods for evaluating the strength of ceramic-ceramic connectors and ceramic-metal connectors: flexural strength, tensile strength and shear strength, among which tensile strength is mainly used in the evaluation of ceramic-metal connection strength in the field of vacuum electronic device preparation. The flexural strength and shear strength are mainly used in the strength evalua...
