Embodiment
Below by way of specific instantiation, embodiments of the present invention are described, those skilled in the art the content disclosed by this instructions can understand other advantages of the present invention and effect easily.The present invention can also be implemented or be applied by embodiments different in addition, and the every details in this instructions also can based on different viewpoints and application, carries out various modification or change not deviating under spirit of the present invention.
It should be noted that, the diagram provided in the present embodiment only illustrates basic conception of the present invention in a schematic way, then only the assembly relevant with the present invention is shown in graphic but not component count, shape and size when implementing according to reality is drawn, it is actual when implementing, and the kenel of each assembly, quantity and ratio can be a kind of change arbitrarily, and its assembly layout kenel also may be more complicated.
The invention provides a kind of measurement jig, measurement jig belongs to a classification below tool, specially to a kind of tool that the function, the calibration of power, life-span, performance etc. of product are tested, tested.Because it is main on a production line for the test of the indices of product, so be measurement jig.Measurement jig of the present invention may be used for the equipment under test testing different model.Described equipment under test can be parts in an integral device.Described equipment under test comprises transformer.Transformer (Transformer) utilizes the principle of electromagnetic induction to change the device of alternating voltage, and main member is primary coil, secondary coil and iron core (magnetic core).In one embodiment, as shown in Figure 1, described measurement jig 1 comprises equipment under test fixed part 11 and test probe adjustment member 12.Wherein:
Equipment under test fixed part 11 is for being fixed on the assigned address of described measurement jig by equipment under test.In one embodiment, described equipment under test fixed part comprises L-type Fixing clamp-seat.Described L-type Fixing clamp-seat comprises two groups of L-type tool moving sliders.The assigned address of described measurement jig comprises the middle position of described measurement jig.Described equipment under test comprises transformer, and described transformer comprises dual inline type transformer.
Test probe adjustment member 12 is connected with equipment under test fixed part 11, for mobile test probe, test probe is connected with the tested pin of described equipment under test.Described test probe adjustment member 12 also for: when test probe is connected with the tested pin of described equipment under test, fixing described test probe.Described test probe adjustment member is by the fixing described test probe such as bolt or set screw.Described test probe is that U-shaped mouth stretches contact-type probe.In one embodiment, described test probe adjustment member comprises moving slide, and described moving slide is arranged in fixing chute; Described test probe is fixed on described moving slide, is controlled the movement of described test probe by described moving slide.In one embodiment, described fixing chute has two, lays respectively at the both sides of the assigned address of described measurement jig.Two moving slide are had in each fixing chute.
In one embodiment, described measurement jig also comprises performance test parts, for being connected the tested pin of described equipment under test by described test probe, carries out correlated performance test to described equipment under test.In the test of reality, determine the tested pin of equipment under test and corresponding transformer performance test component first as required; Equipment under test is fixed on the middle position of described measurement jig; Then, regulate mobile moving slide, make test probe be connected to the tested pin of described equipment under test, and fixing described test probe; Start to carry out performance test to equipment under test.Existing measurement jig, equipment vendors are made with standard configuration form usually, the fixing of the transformer of polytypic and test can not be realized completely in user's hand, test surfaces to transformer limitednumber, for improving testing efficiency, cost-saving, easy to operate, the transformer solving variety classes packing forms can not carry out the problem of testing on same tool.By measurement jig of the present invention, dissimilar tool can be met and be fixed and test, thus greatly facilitate tester and obtain precisely reliably test data.
