The invention relates to the technical field of stator core laminating processes of servo motors with various numerical control machine tool main shaft feeding and other functions and equipment thereof, in particular to a square stator punching sheet laminating tire and a laminating method thereof. The square stator punching sheet laminating tire comprises a bottom tire, a lower pressing ring, anupper pressing tire, an upper pressing ring, a mandrel and an expansion sleeve, wherein a positioning groove is formed in the center of the upper surface of the bottom tire, a first-stage step part and a second-stage step part are arranged at the periphery of the positioning groove from inside to outside and from top to bottom respectively, and the expansion sleeve is arranged in the positioning groove; the inner diameter of the expansion sleeve is matched with the outer diameter of the mandrel, and the lower pressing ring is in clearance fit with the periphery of the first-stage step part andis arranged at the upper part of the second-stage step part; the upper pressing tire comprises an upper plate, a lower plate and a plurality of supporting rods for connecting the upper plate and thelower plate together, a convex part is arranged at the bottom of the lower plate, the upper pressing ring sleeves the periphery of the convex part, and a plurality of bolt holes are formed in the lower plate. The structure is more reasonable, the operation is convenient, and it can be guaranteed that the laminated iron cores are orderly inside and outside.
Description
technical field [0001] The invention relates to the technical field of stator core lamination technology and equipment for servo motors with various CNC machine tool spindle feed and other functions, and in particular to a square stator punch lamination tire and a lamination method thereof. Background technique [0002] Most of the motors used for CNC machine tool spindle feed and mechanical feed for other functions are directly connected to the spindle part of the machine tool or other feed parts. This type of motor cannot be installed outside the machine tool like the motors used in ordinary machine tools. It is basically installed inside the machine tool, so its volume should be as small as possible, and it must dissipate heat quickly. The chip is slightly enlarged as the chassis, and the shape is designed to be a square for easy installation. [0003] Generally, this kind of motor stator laminated tires use a circular mandrel and expansion sleeve. The inner circle of th...
