Description

Motor core punching sheet positioning tool Technical Field The utility model belongs to the technical field of positioning tools, and particularly relates to a motor iron core punching positioning tool. Background The motor core punching sheet positioning tool is key equipment for accurately positioning the core punching sheet in the motor manufacturing process. The design aim is to ensure that the punching sheet always maintains accurate position and relative angle in the links of lamination, assembly and the like, thereby ensuring the manufacturing precision and performance stability of the motor iron core. When the iron core punching sheet is laminated, the pressing direction can rotate, so that the wire grooves of the laminated punching sheet are not neat, the winding difficulty is easily increased, and therefore, the motor iron core punching sheet positioning tool is provided for solving the problem. Disclosure of utility model The utility model provides a motor iron core punching sheet positioning tool, which solves the problems in the prior art. The technical scheme of the utility model is realized as follows: the motor iron core punching sheet positioning tool comprises a pressing plate and a bottom plate which are arranged up and down, wherein a positioning assembly is fixedly arranged at the center of the upper end of the bottom plate, and the periphery of the positioning assembly is sleeved with a punching sheet main body; The positioning assembly comprises a positioning column and positioning blocks arranged along the periphery of the positioning column, a through groove is further formed in the inner periphery of the punching sheet main body, and when the punching sheet main body is sleeved into the positioning column, the end points at the two ends of the positioning blocks are clamped on the inner walls at the two sides of the through groove; the positioning block moves along the inner side of the positioning column, and an adjusting bolt is contacted with the end face of one end of the positioning block, which is close to the positioning column. Furthermore, a cavity is further formed in the inner side of the positioning column, and the adjusting bolt penetrates through the cavity and abuts against the end face of the positioning block. Further, the outer side of the positioning column is further provided with a groove, and one end, away from the positioning block, of the adjusting bolt is located in the groove. Further, the locating blocks are at least provided with two groups, and the quantity of the adjusting bolts is consistent with that of the locating blocks.
