Embodiment Construction

[0039] The existing brushless DC motor Hall seat press-fitting adopts heat-dried end cover, cold-shrink Hall seat, and ordinary indenter visual alignment method for press-fitting. Product performance, and lead to high product repair rate, a large number of scrapped.

[0040] To solve this problem, the present invention proposes a brushless DC motor Hall seat press-fit guide device and method. The device is mainly composed of a positioning base plate, a positioning pin, a spring guide column and a pressing plate.

[0041] Such as Figure 5 As shown, this embodiment is the press-fitting of the Hall seat of the BLDCM-10 (10W) brushless DC motor, and the two positioning holes of the rear end cover are the edge diameters The long arc-shaped positioning holes with an angle of 20°, the Hall installation grooves are 4mm wide grooves with an interval angle of 80°, requiring long holes in the rear end cover The center is aligned with the center of the Hall installation groove, and t...

Abstract

The invention provides a brushless direct current motor Hall seat press fitting guide device which comprises a positioning bottom plate, positioning pins, spring guide columns and a pressing plate. Three positioning holes are formed in the positioning bottom plate and are matched with the positioning pins and the spring guide columns, so that the rear end cover and the Hall seat of the brushless direct current motor are positioned, and the circle center of the long-strip positioning hole of the rear end cover and the center of a mounting groove of the Hall seat are enabled to be on the same straight line. After the press-fitting device is adopted, the precision of the press-fitting position of the Hall seat of the brushless direct current motor can be ensured, the product quality problem caused by human factors is avoided, the product percent of pass is increased, the efficiency is improved, and various performances of the motor are ensured.

Description

technical field [0001] The invention relates to the technical field of installation of a brushless DC motor, in particular to a press-fit guide device for a Hall seat of a brushless DC motor. Background technique [0002] With the continuous development of the motor market, brushless DC motors have been widely used in various fields. For the existing brushless DC motor, the press-fitting of the Hall seat is carried out according to the following procedures: [0003] 1. Baking: Bake the rear end cover at a certain temperature, keep it warm for a certain period of time, and let the end cover heat up. [0004] 2. Liquid nitrogen cooling: Put the Hall mounting base into liquid nitrogen to let the product shrink, which is convenient for pressing. [0005] 3. Press-fitting: Take the rear end cover out of the oven, quickly take the Hall mounting seat out of the liquid nitrogen, and after visually aligning the center of the positioning hole of the rear end cover with the center of...
