Problems solved by technology

However, the shortcomings in the actual production process are: because the built-in positioning is adopted, the magnetic steel is placed in the positioning mandrel, and the magnetic steel is parallel to the inner surface of the casing due to the suction force of the magnetic steel; The steel surface is coated with adhesive, and the adhesive on the surface will be hung up by the end of the casing, resulting in a reduction in the actual use of adhesive, which seriously affects the bonding firmness of the magnetic steel; moreover, due to the suction of the magnetic steel, When pressing into the casing, the resistance is relatively large, and a large force is required to press the magnetic steel in; the production efficiency is low, the reliability of the bonding is poor, and the bonding force is not high, and the magnetic steel is prone to fall off, causing the magnetic steel to fall off. The quality of the motor cannot be guaranteed, and it is not suitable for mass production of motors

Abstract

The invention discloses a stator magnetic steel bonding mold and a bonding method thereof, comprising a base, a casing, a positioning sleeve, a lower positioning plate and an upper positioning plate, the casing is arranged in the base, and the positioning sleeve is placed in the casing Inside, the lower end of the lower positioning plate is fixed on the base by screws, the upper end is connected with the lower end of the upper positioning plate, and the upper end of the upper positioning plate is fixed on the positioning sleeve by screws, and the positioning sleeve is composed of the head and the Composed of inserting sections, fan-shaped positioning holes are evenly arranged inside the head, and bosses are arranged on the fan-shaped positioning holes; the bonding method includes several steps of installing the casing, installing the positioning sleeve and bonding the magnetic steel. In the present invention, when the magnetic steel is bonded, the surface of the magnetic steel and the surface of the casing are in an inclined state, and the magnetic steel and the casing are in line contact, which reduces frictional resistance; prevents the adhesive on the surface of the magnetic steel from being scraped off by the end face of the casing, ensuring The balance of the bonding force of the magnetic steel improves the bonding firmness and prevents the magnetic steel from falling off.

Description

technical field [0001] The invention belongs to the technical field of motor manufacturing, and relates to the bonding of stator magnetic steel in the motor manufacturing industry, in particular to a stator magnetic steel bonding mold and a bonding method thereof. Background technique [0002] The bonding of the existing motor stator magnetic steel mainly adopts the built-in mandrel positioning method. Its tooling structure is as figure 1 As shown, it is mainly composed of a casing 1 and a positioning mandrel 2. The way of using this tool for positioning and connecting magnets is widely used in the production of motors. The bonding process is as follows: (1) Put the positioning mandrel 2 into the casing 1; (2) Put the hand-held magnetic steel 3 into the positioning hole of the positioning mandrel 2; (3) Press the magnetic steel 3 vertically by pressure. into the bottom of the case 1. The bonding method of the magnetic steel has the advantages of convenience, simplicity, ...
