Magnetic pole assembling tool of external rotor motor

Abstract

The invention relates to a magnetic pole assembling tool of an external rotor motor. The magnetic pole assembling tool of the external rotor motor comprises a support guide rail and a magnetic pole assembling clamp, wherein the support guide rail is circular; one end of the support guide rail and one end of an external rotor are fixed together; the inner diameter of the support guide rail is matched with the inner diameter of the external rotor; the magnetic pole assembling clamp comprises a support plate, a magnetic pole pressing screw and a threaded block; the support plate is arranged at one end of the magnetic pole assembling clamp; the threaded block and the magnetic pole pressing screw matched with the threaded block are arranged at the outer end of the support plate; to-be-assembled magnetic poles are arranged on the inner side of the threaded block; the magnetic pole pressing screw is used for pressing inwards to assemble the to-be-assembled magnetic poles to corresponding positions. According to the magnetic pole assembling tool of the external rotor motor, the support guide rail matched with the inner diameter of the rotor is additionally arranged at the end of the motor rotor; by virtue of the magnetic pole assembling clamp arranged on the support guide rail, the to-be-assembled magnetic poles are pressed to the corresponding positions, so that the magnetic poles can be assembled in specific positions under the condition that the magnetic poles are not damaged; the magnetic pole assembling tool is convenient to operate and has time-saving and labor-saving effects.

Description

technical field [0001] The invention relates to the field of motor manufacturing, in particular to a magnetic pole assembly tool for an outer rotor motor. Background technique [0002] Now more and more motors adopt the outer rotor structure, and the magnetic poles of the rotor are generally permanent magnet magnetic poles. When the magnetic poles are installed, because the magnetism of the permanent magnets is relatively large, the attractive force between them and the rotor is very large, which brings great inconvenience to the installation of the magnetic poles. The traditional way to install the magnetic poles is: paste the magnetic poles on the surface of the rotor with their own magnetism, and then the operator moves them to the designated position by hand to fix them. Because the magnetic poles are relatively strong, it is extremely difficult to move the magnetic poles on the rotor surface, which takes time and effort. , in order to move the magnetic pole to the desi...

Problems solved by technology

When installing the magnetic poles, due to the strong magnetism of the permanent magnets, it has a strong attraction force with the rotor, which brings great inconvenience to the installation of the magnetic poles.

The traditional way to install the magnetic poles is: paste the magnetic poles on the surface of the rotor with their own magnetism, and then the operator moves them to the designated position by hand to fix them. Because the magnetic poles are relatively strong, it is extremely difficult to move the magnetic poles on the rotor surface, which takes time and effort. , in order to move the magnetic pole to the specified position, the operator often hits the magnetic pole with a wooden hammer to make fine adjustments in the position, which is very easy to damage the magnetic pole
