The invention provides a lead pressing device for per-meter resistance measurement. The lead pressing device can solve the problem that measuring accuracy is affected due to the fact that pressing force of an existing lead pressing device is not easy to control and can effectively avoid non-uniformity of pressing force at two ends of a lead to be measured and improve measuring accuracy and can greatly improve measuring efficiency. The lead pressing device for per-meter resistance measurement comprises a base, a left metal contact block and a right metal contact block are symmetrically mounted at two end of the base, and a left pressing plate and a right pressing plate are mounted above the left metal contact block and the right metal contact block through a left support and a right support. The lead pressing device is characterized in that a left air cylinder and a right air cylinder are mounted on the left support and the right support respectively, the left pressing plate and the right pressing plate are connected with pistons of the left air cylinder and the right air cylinder respectively, and the left air cylinder and the right air cylinder are respectively connected with a pressure regulator through a left air valve and a right air valve.
Description
technical field [0001] The invention relates to the technical field of wire resistance measurement, in particular to a wire pressing device used for measurement of the resistance of a wire. Background technique [0002] By measuring the value of the meter resistance, the resistivity of this material can be converted, and the resistivity is the property that reflects the resistance of the material to the current, and the resistance is the property that reflects the resistance of the object to the current. Therefore, resistance is an important factor for the manufacture of transformers and magnet wires. important indicator. The existing wire pressing device for meter resistance measurement includes base 1, metal contact blocks 2, 3, pressing plates 6, 7, see figure 1 and figure 2 , the lateral ends of the base 1 are symmetrically installed with metal contact blocks 2 and 3, and pressure plates 6 and 7 are respectively arranged above the metal contact blocks 2 and 3 at both ...
