Stress test jig for magnetic material

Abstract

The invention discloses a stress test jig for a magnetic material. The stress test jig comprises a test base body, a test clamp and multiple test stop blocks, wherein the test clamp is mounted at the middle part of the test base body in a locking manner through a pin; at least one test point is arranged on each side of the test clamp; the multiple test stop blocks press against the magnetic material to fix the magnetic material on the test clamp; each test stop block is formed by stacking a trapezoid block and a triangular block, and test points are arranged on two sides of the trapezoid block and the sides of the triangular block; the test points on the test clamp and the test stop blocks are connected with the test base body through test lines. The stress test jig is reasonable in structural design; as the test points are arranged on the test clamp and the test stop blocks, synchronous test in multiple directions can be realized, and the test precision is high; furthermore, tests for multiple magnetic materials can be completed at one time; by distribution of multiple test stop block positions, the stress test jig can adapt to the test work for the the magnetic materials of different specifications, and is high in working efficiency and high in universality.

Description

technical field [0001] The invention relates to the technical field of electronic information materials, in particular to a magnetic material stress testing jig. Background technique [0002] During the casting, welding, forging and mechanical cutting process of magnetic materials, due to the deformation caused by thermal expansion and contraction and mechanical force, residual stress is generated inside the part, which makes the part in an unstable state and reduces the dimensional stability and mechanical physics of the part. Performance, so that the parts will deform and fail due to the release of residual stress during the use of the finished product. Therefore, in order to ensure safety during use, the residual internal stress of various magnetic material products is stipulated not to exceed a certain specified value, but the test fixture in the stress testing device of the prior art can only clamp one part at a time, thus As a result, the testing equipment can only pe...

Problems solved by technology

Therefore, in order to ensure safety during use, the residual internal stress of various magnetic material products is stipulated not to exceed a certain specified value, but the test fixture in the stress testing device of the prior art can only clamp one part at a time, thus As a result, the testing equipment can only perform stress testing on one part at a time, which is time-consuming, labor-intensive, high-cost, and low-efficiency, which cannot meet the requirements of modern industry

Moreover, the flexibility of the test fixture stopper is poor, usually only the stress test in the horizontal direction can be realized, and the test accuracy is low
