Motor rotor press-fitting tool and corresponding mounting method

Abstract

The invention provides a motor rotor press-fitting tool which is low in cost, small in occupied area, rapid in assembly and positioning and high in assembly efficiency and meets the mass production requirement. An upward convex positioning ring sleeve is arranged in the center of the base, and a plurality of inwards-concave receding grooves are annularly distributed in the upper end face of the positioning ring sleeve. A positioning threaded hole is formed in the center of each avoiding groove, a positioning support comprises a lower guide sleeve and an upper positioning sleeve, the diameter of the inner ring cavity of the lower guide sleeve is smaller than that of the guide cavity of the upper positioning sleeve, the inner ring part of the upper end surface of the lower guide sleeve is provided with a concave positioning pin hole corresponding to the rivet hole of the rotor core, the motor rotor press-fitting tool further comprises a matched positioning pin, the positioning pin is inserted into the inwards-concave positioning pin hole and then protrudes upwards, the upwards-protruding positioning pin is used for circumferential positioning of the rotor iron core, the positioning ring sleeve is sleeved with the lower guide sleeve, a guide cavity is formed between an inner ring cavity of the lower guide sleeve and the upper end face of the positioning ring sleeve, and a guide ejector pin assembly is arranged in the guide cavity.

Description

technical field [0001] The invention relates to the technical field of motor rotor assembly, in particular to a motor rotor press assembly tool, and the invention also provides a corresponding motor rotor assembly method. Background technique [0002] The motor rotor includes a motor shaft, a rotor core, and two balanced end plates located on the end face of the rotor core axis. During the assembly process of the existing motor rotor, different equipment at different stations are required for assembly. It is used to assemble the motor rotor The cost is high, the floor area is large, and multiple alignments are required during assembly, which makes the assembly efficiency low and cannot meet the needs of mass production. Contents of the invention [0003] In view of the above problems, the present invention provides a motor rotor press assembly tool, which has low cost, small occupied area, quick assembly and positioning, high assembly efficiency, and meets mass production ...
