Description

Technical Field

[0001] The invention relates to the technical field of assembly equipment, in particular to a motor assembler for an electric vehicle. Background Art

[0002] The motor is commonly known as the motor, which is a relatively important part of electromechanical equipment. The motor is equipped with a rotor and a stator. When the motor is powered on, the rotor coil rotates to cut the stator magnetic field and make circular motion. The motor is a device that converts electrical energy into mechanical energy and converts it into different modes of motion through various transmission structures. In the general assembly process of the motor, the assembly process of the motor stator plays a key role in the assembly accuracy of other accessories.

[0003] In the prior art, a patent document with announcement number CN221305704U discloses a motor stator assembly device, including: a mounting base plate, a support rod and a top plate, the top of the mounting base plate is provided with a movable groove, a mounting frame, and the top of the mounting frame is fixedly connected with a placement table. The utility model realizes a motor stator assembly device through the mutual cooperation between the mounting base plate, the support rod, the top plate, the movable groove, the mounting frame, the limiting mechanism, the displacement mechanism, the pressing mechanism, the rubber pad and the placement table. The housing and the stator are placed in the placement groove on the top of the placement table. Under the elastic action of the reset spring, the support frame is pushed to limit the position of the stator. When the placement table reaches the corresponding position, the cylinder pushes the pressing block to press the stator into the housing. Due to the limitation of the supporting frame, the position of the stator can always remain stable during the movement or pressing process, avoiding the displacement of the position of the stator and the housing due to vibration, thereby ensuring the qualified rate of the product.

[0004] During use, it was found that when the above-mentioned device assembles and clamps the motor stator through the connecting rod, the return spring and the support frame, the staff needs to make manual adjustments, which increases the labor intensity of the staff and is less convenient.

When the protective plate 503 moves to between the photoelectric signal transmitter 507 and the photoelectric signal receiver 508, the protective plate 503 closes the photoelectric signal transmitter 507 and the photoelectric signal receiver 508. When the line signal is cut off, the controller 103 operates the electric hydraulic cylinder 403 to extend, so that the lifting plate 404 drives the lower pressing block 405 to move downward with the cooperation of the light rod 406, and further makes the lower pressing block 405 press the stator on the outer shell, so as to realize the assembly of the outer shell and the stator. After the pressing is completed, the positioning seat 204 moves forward, and the two sets of guide wheels 303 move from the rear part of the guide groove 104 to the front part of the guide groove 104, so that the two sets of support arms 302 move away from each other in a mirror image, so as to realize the release of the clamping of the outer shell assembly.

[0024] The controller 103, servo motor 201, photoelectric signal transmitter 507, photoelectric signal receiver 508 and electric hydraulic cylinder 403 of the motor assembler of an electric vehicle of the present invention are purchased on the market. Technicians in the industry only need to install and operate them according to the accompanying instruction manual, without the need for creative work by technicians in this field.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
