Multi-specification circuit breaker coil element test jig

Abstract

The invention relates to the technical field of test and especially relates to a multi-specification circuit breaker coil element test jig. The multi-specification circuit breaker coil element test jig comprises a base, a cover plate and corresponding locating shafts arranged in the base. The base is provided with a lower locating hole, a convex bench and a corresponding lower detection hole. Thecover plate is provided with an upper locating hole, an upper detection hole and a groove corresponding to the convex bench. The diameters of the locating shafts are set to detect internal diameters of corresponding coils; and the convex bench and the groove are same in height, and are cooperated to detect length of the corresponding coils. Each locating shaft finishes inner diameter measurement of each specification of coil and positioning in the vertical direction, so that each locating shaft serves as measuring basis for each detected coil, and the locating shafts also play roles of positioning support, guiding and balance in the overall structure.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a test jig for multi-standard circuit breaker coil components. Background technique [0002] The coil is the key component that affects the electromagnetic performance in the circuit breaker. There are many product specifications for the general small circuit breaker, and each specification corresponds to a different coil component, and each coil has its own shape and size. For the coil The detection of the dimensional characteristics is generally measured by general-purpose measuring tools such as vernier calipers and height gauges. The detection speed is slow, the measurement reference is difficult to find, the accuracy is poor, and the efficiency is low. Contents of the invention [0003] In view of the above problems, the present invention provides a multi-standard circuit breaker coil element test fixture, which can improve the inspection quality and detection efficiency. ...
