Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0020] The utility model relates to an expanding tire for manufacturing cast aluminum rotors, which is composed of three parts: an expanding core, an expanding sleeve and a washer. The expansion core, expansion sleeve, gasket and their specific combination state will be mentioned in detail in the following content.
[0021] Such as figure 1 As shown, the expansion core includes a circular base 1, and a vertical expansion core rod 2 is fixed in the center of the circular base 1, and an expansion part is provided on the rod wall from the bottom of the expansion core rod 2 to the middle of the expansion core rod 2 3
[0022] Such as figure 1 As shown, the expansion part 3 is a conical frustum.
[0023] Such as figure 1 As shown, a circular washer stopper 5 is provided on the surface of the base 1 at the periphery of the bottom of the core rod 2, and t...

The invention relates to an expander used for manufacturing a cast-aluminum rotor. In order to effectively guarantee the coaxiality of shaft holes of the cast-aluminum rotor in the manufacturing process, the expander used for manufacturing the cast-aluminum rotor is composed of three parts including an expansion core, an expansion sleeve and a washer. Rotor sheets are installed on the expansion sleeve in an overlapped mode and subjected to downward acting force to drive the expansion sleeve to move downward along the conical surface of the expansion core, and rotor sheet holes are expanded to be flush with one another through the expansion sleeve. The expander can guarantee the coaxiality of the shaft holes of the cast-aluminum rotor, thereby improving product quality and effectively lowering a rejection rate. The expander used for manufacturing the cast-aluminum rotor is simple in structure, low in cost, reasonable in process, and capable of improving production efficiency substantially.
Description
technical field [0001] The invention relates to an inflatable tire for manufacturing cast aluminum rotors. Background technique [0002] In the production of small and medium-sized motors, the cast aluminum rotor is an indispensable tooling in the production, and the quality of the shaft hole of the cast aluminum rotor directly affects the stability of the motor operation. If in the process of manufacturing the cast aluminum rotor, the shaft holes of the rotor punches cannot be aligned, the coaxiality of the manufactured cast aluminum rotor shaft holes cannot be guaranteed, and when the true shaft is installed, it will affect the alignment with the true shaft. Coordination will have a great impact on the performance of the motor. Contents of the invention [0003] In order to ensure the coaxiality of the shaft hole effectively during the manufacturing process of the cast aluminum rotor, the invention provides a tire expander for the manufacture of the cast aluminum rotor....
