Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail a preferred embodiment of the present invention with reference to the accompanying drawings to facilitate understanding of the skilled person.

As shown in fig. 1-3, the simple stator bar quick positioning tool comprises a support column 1, a graduated column 2 and an auxiliary ruler 3, wherein one end of the support column 1 is provided with a U-shaped groove, the other end of the support column is fixedly connected with the graduated column 2 through welding or integral forming and the like, standard lines are marked on the side wall of the graduated column 2, and the auxiliary ruler 3 is perpendicular to the graduated column 2. The scale column is also marked with good determination lines and qualified determination lines, the good determination lines are symmetrically distributed by taking the standard line as a symmetry axis, the distance from the standard line is 3mm, the qualified determination lines are symmetrically distributed by taking the standard line as a symmetry axis, the distance from the standard line is 5mm, the areas between the good determination lines are good areas, and the areas between the qualified determination lines are qualified areas. The U type groove card of seting up on support column 1 is on the tooth clamp plate 5 that compresses tightly with 4 terminal surfaces of stator core, and tooth clamp plate 5 is striden across to U type groove both ends face, withstands 4 terminal surfaces of stator core, because U type inslot card on support column 1 has tooth clamp plate 5, and U type groove both ends face withstands 4 terminal surfaces of stator core simultaneously after, the incline can not appear in measurement process in support column 1, has guaranteed the measurement process, the vertical stability of support column 1 and 4 terminal surfaces of stator core.
