A quick fixture for in-situ testing

Abstract

The invention discloses a rapid clamp for in-situ test. The rapid clamp for in-situ test overcomes the defects that labor is consumed, the efficiency is influenced, the positioning precision of the clamp and the performance of parts are affected, and the whole clamp needs to be replaced. The rapid clamp comprises a machine frame (2), a pneumatic / hydraulic power part, a connecting rod sliding blockmechanism, two positioning clamping elements (14) with the same structure, and two 180-degree rotation indexing mechanisms; the pneumatic / hydraulic power part is mounted in the machine frame (2); theconnecting rod sliding block mechanism is mounted below the pneumatic / hydraulic power part; the pneumatic / hydraulic power part is fixedly connected with a fixed block (5) in the connecting rod sliding block mechanism through a pneumatic / hydraulic cylinder (17) in the pneumatic / hydraulic power part; the two 180-degree rotation indexing mechanisms are symmetrically mounted on two sliding blocks (17) in the connecting rod sliding block mechanism through two bearings (18) in the 180-degree rotation indexing mechanisms, and are in rotation connection; and the two positioning clamping elements (14)are mounted at the inner ends of the two bearings (18) in the 180-degree rotation indexing mechanisms.

Description

technical field [0001] The invention relates to a fixture in the field of material mechanical performance testing technology and mechanical design and manufacture. More specifically, the invention relates to a quick fixture for in-situ testing of microscopic mechanical properties of materials with multiple loads. Background technique [0002] Most of the traditional mechanical performance tests of materials obtain test result data by applying a single load. However, the loads on materials under actual service conditions are relatively complex. Therefore, it is difficult for traditional single-load material mechanical performance tests to approach or completely simulate the failure of materials under actual working conditions. And the evolution mechanism, which in turn affects the preparation process and actual use of materials, and may eventually cause unexpected damage and harm. The in-situ test of the mechanical properties of multi-load materials is to simulate the actual ...
