Motor

Abstract

The utility model discloses a motor and an assembling method thereof. The assembling method comprises a preposing assembling step, an assembling positioning step, and a finished product assembling step, wherein the preposing assembling step refers to assemble an axle tube internally-installed assembly inside an axle tube; the assembling positioning step refers to heat one thermoplastic positioning portion of the axle tube with the help of a heating gauge, thereby positioning the axle tube internally-installed assembly inside the axle tube after the thermoplastic positioning portion is cooled and solidified; and the finished product assembling step completes the assembling of one stator set and one rotor, thus to form the motor structure. The motor and the assembling method thereof can utilize a hole-shrinking structure formed by the thermoplastic positioning portion to positioning the axle tube internally-installed assembly, thus to effectively cut down the overall manufacturing cost and reduce the structural complexity.

Description

technical field [0001] The invention relates to a motor, in particular to a motor capable of effectively positioning components in a shaft tube of the motor. Background technique [0002] Please refer to figure 1 As shown, it is a "cooling fan" disclosed in Taiwan Invention No. I287962 patent case. During the assembly process of the cooling fan 8 , it is mainly designed by means of several circularly arranged and flexible four straight strips 811 of the shaft sleeve 81 . At this time, the four straight parts 811 can be pulled out to be in a curved state, so that the dynamic bearing 82 can be smoothly assembled inside the shaft sleeve 81, and then the straight parts 811 can be reset to an upright state, and the dynamic bearing 82 can be positioned Inside the shaft sleeve 81 , the follow-up assembly work can be completed accordingly. [0003] However, in the actual use of the cooling fan 8 structure formed by the existing assembly method, since the four straight parts 811 o...

Problems solved by technology

[0005] However, with the motor 9 formed by this existing assembly method, in order to ensure that the stopper 941 of the stator set 94 can indeed locate the "shaft tube internal assembly" inside the shaft tube 93, the structure of the stator set 94 must be In addition, the design of the limiting member 941 is formed, so the structure of the stator group 94 is too complicated, and the manufacturing cost of the stator group 94 is increased; During the process of pressing against and positioning the "shaft tube inner components" by the positioning part 941, it is easy to be difficult to grasp due to the assembly force, which may cause cracks or breakages in the limiting part 941 of the stator group 94, and also cause many problems in the assembly. In addition to being inconvenient, it is also impossible to effectively locate the "shaft tube internal assembly"
