Description
Technical Field
The invention relates to a biaxial bending test tool assembly, in particular to a positioning cover in a ring-on-ring biaxial bending strength test tool and a ring-on-ring biaxial bending strength test fixture comprising the positioning cover.
Background
The ring-on-ring biaxial bending test (ring-on-ring biaxial bending test) is a classical method for testing the bending strength of structural ceramics. According to ASTM standards, the clamp consists of a loading clamp comprising a loading ring mounting part and a loading ring, and a supporting clamp comprising a supporting ring mounting part and a supporting ring (as shown in fig. 1), wherein a test sample is positioned between the loading ring and the supporting ring, and the relative movement of the upper ring and the lower ring in the vertical direction causes the sample to bend, and the bending strength is the maximum stress of the sample when the sample is bent and broken between the upper ring and the lower ring.
However, this clamp design has a number of problems during actual use. Firstly, when the fixture and the sample are installed, the center axis positioning of the loading ring and the supporting ring is required to be accurate to 0.5% of the diameter of the supporting ring, the center axis positioning of the sample and the upper ring and the lower ring is required to be accurate to 2% of the diameter of the supporting ring, if the center offset of the loading ring, the upper ring and the lower ring is too large, stress distribution is uneven, the fracture starting point is always positioned near the loading ring, in actual operation, the manual correction error is large, the loading ring, the supporting ring, the upper ring and the lower ring cannot be accurately centered, invalid fracture is generated, and time is consumed. And in the process of the relative movement of the loading ring and the supporting ring, the test sample is shifted, and the stress concentration phenomenon can be caused by the line or point contact stress and the friction force between the upper ring and the lower ring and the test sample, so that the test sample is broken under the stress beyond the actual bending strength, and the experimental result is inaccurate. In addition, the device is difficult to collect after sample fracture due to lack of a structure for containing the sample, and the later experiment is inconvenient to carry out.
Disclosure of Invention
The invention aims at: in response to all or part of the above problems, a positioning cover is provided that assists in positioning the Ji Jiazai ring, support ring and central axis of the test specimen. To perform high precision and rapid alignment of the loading ring, the support ring and the central axis of the test sample.
The technical scheme adopted by the invention is as follows:
the positioning cover for the ring-on-ring biaxial bending strength test fixture comprises a loading ring mounting part, a supporting ring mounting part, two mounting parts (the loading ring mounting part and the supporting ring mounting part) are oppositely arranged, wherein the loading ring mounting part is provided with a loading ring at the bottom, the supporting ring mounting part is provided with a supporting ring at the top, and the supporting ring top is used for placing a test sample; the bottom of the positioning cover is provided with a containing cavity for containing the test sample, and the size of the containing cavity corresponds to the size of the test sample; the bottom of the positioning cover is provided with a mounting mechanism for mounting the positioning cover on the supporting ring mounting part; the top of the accommodating cavity extends along the top direction of the positioning cover, a channel is formed, the size of the channel corresponds to the size of the loading ring installation part, and when the loading ring installation part is arranged in the channel, the loading ring installation part can axially move along the channel in the channel; the channel position is designed as follows: when the positioning cover is mounted on the supporting ring mounting part through the mounting mechanism, the central axis of the loading ring connected with the loading ring mounting part in the channel is overlapped with the central axis of the supporting ring connected with the supporting ring mounting part; the position design of the accommodating cavity is as follows: when the positioning cover is mounted on the supporting ring mounting part through the mounting mechanism, the central shaft of the accommodating cavity is overlapped with the central shaft of the supporting ring.
The positioning cover is mounted on the supporting ring mounting part through the mounting mechanism, so that the relative position between the positioning cover and the supporting ring mounting part is determined, and the relative position between the accommodating cavity and the supporting ring can be determined. By providing a channel in the positioning cover, the relative position of the load ring and the receiving cavity can be determined. Therefore, the relative positions among the loading ring, the supporting ring and the test sample can be determined, the center axes of the loading ring, the supporting ring and the test sample are aligned, the concentricity of the loading ring, the supporting ring and the test sample is improved, the alignment speed is high, the result is accurate, and no error occurs. The size of the accommodating cavity designed by the positioning cover corresponds to that of the test sample, so that the position of the test sample in the test process can be prevented from shifting, the center axes of the support ring, the loading ring and the test sample in the test process are kept consistent, and stress concentration is avoided to a certain extent.
Further, the mounting mechanism is designed to: when the positioning cover is mounted on the supporting ring mounting part, the accommodating cavity of the positioning cover forms a closed space.
The closed accommodating cavity can effectively prevent broken test samples from sputtering around.
Further, the mounting mechanism includes at least one limit structure that uniquely identifies the location of the positioning cap to the support ring mounting portion. That is, the mounting mechanism can uniquely determine the pose of the positioning cover on the support ring mounting portion. It should be noted that, the posture is identical to the original posture after rotation and overturning due to the symmetrical relation, and the same posture, namely "unique determination" is considered here, only the whole posture is considered, and the position where the part is located is not considered. For example, the ring is regarded as the same posture in any state of rotation around the center axis.
Further, one of the limiting structures at least surrounds a portion of the periphery of the support ring mounting portion. Namely, in the installation completion state of the positioning cover, the limiting structure is positioned around the supporting ring installation part.
Further, the mounting mechanism at least comprises two limiting structures which are oppositely arranged. The two relative positions can accurately determine the pose of the positioning cover.
In order to solve all or part of the problems, the invention also provides a ring-on-ring double-shaft bending strength test fixture which comprises a support ring, a support ring mounting part, a loading ring mounting part and the positioning cover, wherein the loading ring mounting part is opposite to the support ring mounting part, the loading ring is mounted at the bottom of the loading ring mounting part, the support ring is mounted at the top of the support ring mounting part, the positioning cover is mounted on the loading ring mounting part through a mounting mechanism, and the loading ring mounting part is arranged in a channel of the positioning cover.
The fixture can be used for rapidly and accurately aligning the loading ring, the supporting ring and the center shaft of the test sample during installation, and can prevent the position of the test sample from deflecting during the test process.
Further, at least one of the loading ring and the supporting ring is mounted at the bottom middle of the corresponding mounting portion. I.e. the loading ring and/or the support ring is mounted in the centre of the corresponding mounting portion.
The top of the mounting part of the further support ring is provided with a storage cavity. The receiving cavity can collect the broken test sample.
Further, the opening of the receiving cavity is located in the supporting ring. This further ensures a firm support of the support ring by the support ring mounting.
Further, the inner diameter of the passage of the positioning cover is 0.05mm longer than the diameter of the loading ring mounting portion. Therefore, the movable latitude can be reserved between the channel and the loading ring installation part, and the abrasion between the channel and the loading ring installation part is reduced.
Further, the surface of the channel of the positioning cover and/or the side surface of the loading ring mounting part corresponding to the channel are smooth surfaces.
Because the loading ring installation part needs to move in the channel (testing process), the abrasion between the loading ring installation part and the channel can be effectively reduced by the design, and the error in later positioning is prevented.
In summary, due to the adoption of the technical scheme, the beneficial effects of the invention are as follows:
1. the positioning cover can restrict the loading ring, the supporting ring and the test sample, so that the center shaft of the loading ring, the supporting ring and the test sample can be quickly aligned, errors of manual correction are prevented, the fixture mounting and calibrating time is shortened, and the test efficiency is improved.
2. The positioning cover can prevent broken sample fragments from being sputtered everywhere, and has good limiting effect on the movable space.
3. The fixture can ensure the stability of the loading ring, the supporting ring and the center shaft of the test sample in the working process, and improves the test accuracy.
4. The clamp can collect broken samples and ensure the integrity of sample fragments.
