Abstract
The utility model relates to a microimpact test platform, comprising a base. A test piece, a Y work platform, an X work platform, a supporting seat and an outer cover are respectively connected to the base. The utility model can be used for impact tests for material of small volume. The utility model has the advantages of small size, light weight, low price, adjustable impact distance, etc.
Description
The utility model relates to a kind of testing tool, particularly a kind of microshock testing table.
At present, domestic shock table all is applicable to the impact experiment of large volume material, and the small size material impact testing table that is applicable to micromechanics does not appear in the newspapers, along with micromechanics manufacturing technology and application and development and going deep into to micromechanics research, requirement is to the static state of measuring technology from having set up of micromechanics and material, the quasistatic technology, as micro-indentations, little cut and off-load are measured to impression fatigue, microshock, dynamically the direction of technique of dynamic measurement such as cut and rubbing wear detection develops, and impact loading device and technique of dynamic measurement are the indispensable important means of carrying out this respect research.
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, proposes a kind of microshock testing table that is applicable to micromechanics small size material, has simple in structure, convenient test, cheap, characteristics that impact distance is adjustable.
Accompanying drawing is a structure principle chart of the present utility model.
Below in conjunction with accompanying drawing structural principle of the present utility model and workpiece principle are done to say in detail Bright.
With reference to accompanying drawing, the utility model comprises a L type base 1, left side at L type base 1 is connected with test specimen 2, y work stage 6 and x work stage 7 are housed respectively on the surface level of L type base 1, dispose a bearing 8 on the x work stage 7, one " U " type outer cover 11 is housed on bearing 8, be equipped with in the exit of " U " type outer cover 11 by two pairs of slice springs 5 and hang the drift 3 of getting up, behind drift 3, be equipped with the block stamp 9 that is coupled together by two pairs of slice springs 5 equally, behind block stamp 9, be connected with a "T"-shaped iron core 10, coil 12 be housed respectively at the upper and lower of "T"-shaped iron core 10.
The utility model adopts electromagnetism loading, energy conversion principle to carry out impulse test.Drift 3 and block stamp 9 are hung by two pairs of slice springs 5 respectively, flat spring 5 is guiding, support components of drift 3 and block stamp 9, can pilot punch 3 and the motion of ram hammer 9, when adding a suitable electric pulse to the utility model, because the effect of magnetic force, iron core 10 meeting accelerated motions left, give 9 one impulsive forces of block stamp, pass to drift 3 by block stamp 9, by drift 3 energy is transferred on the test test specimen 2, afterwards again, drift 3 is under the effect of flat spring 5 restoring forces, test specimen 2 surfaces that speed away form a pressure pulse, finish the impact to subjects.In this process, size by the force transducer that is contained in drift 3 inside and speed pickup record impulsive force and impact velocity, for guaranteeing the operate as normal of loading section, used soft iron core in the coil 12, so both strengthened electromagnetic induction, make that again energising is magnetic, it is nonmagnetic to cut off the power supply, and does not have remanent magnetism.
The utlity model has characteristics such as volume is little, in light weight, low price, impact distance is adjustable in addition, and the impact distance scope is between 0.7~2.0mm, is applicable to the impulse test of small size material.
Materials such as 5J20110 bimetallic alloy, aluminium, silicon have been carried out impulse test, got a desired effect.
