Problems solved by technology
[0002] Students in engineering schools have to complete the learning process of mechanical properties in their studies. The teaching content of the students includes tensile tests on the boards, especially the stretching of the parts with holes on the boards, so that students can observe the Changes in strength and toughness, through the tensile test to understand the tensile change process of the plate. However, the special tensile test fixtures on the school tensile testing machine are relatively rare, and it is not possible to test all the plates with different thicknesses. Student experiments cause a lot of inconvenience

The invention provides a tensile test clamping device, used for teaching, for perforated plates different in thickness specifications. The tensile test clamping device includes a clamp pedestal and ahole connection clamp body that are fixedly connected to a drawing machine. One end of the upper end face of the clamp pedestal is fixedly connected to a two-side fixed clamp. The upper end face of the clamp pedestal is in sliding connection with a two-side sliding clamp. When the a two-side sliding clamp slides to match the a two-side fixed clamp, two ends of a to-be-tested plate are clamped. Thehole connection clamp body is composed of a transverse plate and a middle fixed clamp plate to be of an inverted L-shaped structure. The lower end face of the transverse plate is slidably connected with a middle sliding clamp plate that is combined with the middle fixed clamp plate to clamp the middle of the to-be-tested plate. The middle fixed clamp plate, the to-be-tested plate and the middle sliding clamp plate are connected together through fastening structures. The tensile test clamping device can clamp plates different in thickness to carry out a tensile test, has a simple structure, isconvenient for clamping, is high in stability, conveniently clamps plates different in thickness, and brings convenience for students to carry out a tensile test.
Description
technical field [0001] The invention belongs to the technical field of fixtures used in teaching, and in particular relates to a clamping device for tensile tests of plate parts with holes in different thickness specifications for teaching. Background technique [0002] Students in engineering schools have to complete the learning process of mechanical properties in their studies. The teaching content of the students includes tensile tests on the boards, especially the stretching of the parts with holes on the boards, so that students can observe the Changes in strength and toughness, through the tensile test to understand the tensile change process of the plate. However, the special tensile test fixtures on the school tensile testing machine are relatively rare, and it is not possible to test all the plates with different thicknesses. Student experiments cause a lot of inconvenience. Therefore it is necessary to propose improvements. Contents of the invention [0003] T...
