Problems solved by technology

Existing fixtures usually have a single function, and often need to manually complete the pressing work, and manual clamping cannot be performed in the environment of high temperature and radiation under airtight conditions; and some automatic fixtures also have the problem of cumbersome and complicated operations. The centering performance of sample and workpiece clamping is poor, which often leads to unsatisfactory test results

Embodiment Construction

[0030] In order to further understand the content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0031] Such as Figure 1 to Figure 4 As shown, this embodiment provides a quick clamp suitable for a closed environment, which includes two symmetrically arranged clamp assemblies, and each clamp assembly includes a mounting platform and a pressing mechanism.

[0032] combine Figure 5 As shown, the installation platform includes a platform body 8 , a slideway stopper 4 and a limit stopper 5 .

[0033] The platform body 8 includes a testing machine mounting part 801 and a sample clamping part 802 integrally connected, the testing machine mounting part 801 is used to be connected with the testing machine, and the sample clamping part 802 is used to place a plate-shaped sample 7, thereby completing the alignment. Test operations such as tension and com...

Abstract

The invention belongs to the technical field of material performance testing, and discloses a rapid clamp suitable for a closed environment. The rapid clamp comprises two symmetrically arranged clampassemblies, and each clamp assembly comprises a mounting platform and a pressing mechanism; the mounting platform comprises a platform body, a slideway baffle plate and a limiting baffle plate; and the pressing mechanism comprises a pressing handle, a limiting sliding block and a sample pressing block. The rapid clamp is easy and convenient to operate, a sample can be automatically clamped througha mechanical arm, manual operation in an extreme environment is avoided, contact of harmful substances is reduced, and personal safety is effectively guaranteed; because the sample can be compressedafter a test condition is applied, a local stress generated by fixing the sample in advance can be avoided, and the accuracy of test data is guaranteed; and meanwhile, centering performance is good, atest process is safe and a result is reliable.

Description

technical field [0001] The invention belongs to the technical field of material performance testing, and in particular relates to a fixture suitable for matching SEM and other closed environment testing conditions. Background technique [0002] With the rapid development of modern industries such as aerospace and nuclear power, the number of equipment serving in high-temperature vacuum environments and nuclear radiation conditions is gradually increasing. Due to the particularity of the vacuum high-temperature environment and nuclear radiation conditions, equipment materials are often inevitably damaged to varying degrees. If the equipment materials cannot withstand such harsh working conditions for a long time, it is easy to cause device and equipment failure, and in severe cases, the equipment will be damaged. Leakage, component failure, nuclear pollution and other vicious accidents. Therefore, the safety performance evaluation and mechanical performance testing of materi...
