Description

Technical Field

[0001] This utility model specifically relates to the field of motor technology, and more specifically to a tooling for press-fitting the stator and housing of a motor. Background Technology

[0002] An electric motor (English: Electric machinery, commonly known as a "motor") is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It is represented by the letter M in circuit diagrams (D in older standards). Its main function is to generate driving torque, serving as a power source for electrical appliances or various machines. A generator is represented by the letter G in circuit diagrams. Its main function is to convert mechanical energy into electrical energy.

[0003] Chinese utility model publication number CN 213937688 U discloses a tooling for press-fitting a stator and a housing of an electric motor, including a base plate, a lower mold for supporting the stator on the base plate, guide posts on the base plate located on both sides of the lower mold, an intermediate plate on the guide posts, a positioning component for the stator to pass through and for positioning the housing on the intermediate plate, and an upper top plate, with connecting rods fixed on both sides of the upper top plate, the lower end of the connecting rods having an oblong hole, connecting posts on both sides of the intermediate plate fitting into the oblong hole, and a pressure head cap connected to a power machinery on the upper top plate;

[0004] The aforementioned fixture for press-fitting the stator and housing of a motor involves placing the stator on a lower mold and the housing on a positioning assembly on an intermediate plate. Because the connecting rod and intermediate plate are connected via an oblong hole and a connecting post, the connecting post can move within the oblong hole. The connecting post is located at the lower end of the oblong hole, ensuring that the distance between the upper top plate and the intermediate plate is greater than the height of the housing, facilitating the placement of the housing into the positioning assembly. When the equipment is operating, the connecting post moves upward along the oblong hole until the upper top plate abuts against the upper end of the housing. The upper top plate then pushes the housing and intermediate plate downward until the housing and stator are aligned. The assembly process is simple; however, this method requires individual material loading and assembly, and the next material can only be loaded and assembled after the previous one is completed. This is inconvenient and cannot be done in a streamlined manner. To address this, we provide a stator and housing press-fit fixture for the motor. The housing and stator are continuously fed by a vibrating feeding plate and a vibrating feeding plate, respectively. The housing and stator are then pressed together on the press-fit frame, and finally pushed out on the discharge rack. This allows for continuous material feeding, unloading, and assembly, making it more convenient to use, improving work efficiency, and effectively overcoming the aforementioned problems.
