Technical Field
The utility model belongs to the technical field of the data measurement, concretely relates to bar sample magnetic force measuring platform.
Background
At present, most of post-fracture gauge length measurement of traditional metal bar-shaped samples is carried out by using vernier calipers, original gauge length points need to be marked on the surfaces of the bar-shaped samples before tests, after the samples are broken, the fractured samples are taken out and tightly spliced and placed on a working table, so that the marked points are just opposite to a measurer, the tips of the vernier calipers are tightly attached to the required marked points, the samples are tightly attached after the fractures, the marked points are located on the same straight line, the samples are ensured not to move or rotate during measurement, and the vernier caliper data are read by manual visual inspection. However, in actual measurement, when the caliper is in contact with a sample, due to the shape of the rod-shaped sample, the measured sample may move or rotate with a high probability, which may cause misoperation of a measurer or require repeated measurement, thus it is difficult to ensure the accuracy of the measured data, and data distortion may occur, which may seriously affect the working efficiency. Under the condition that the original gauge length is smaller, the distortion of the post-fracture gauge length measurement data has a great influence on the calculation result of the elongation rate, and if the distorted data is not found, the risk of difficult estimation is caused to companies and clients.
