[0002] The motor core is an important component inside the motor and the core component that supports the operation of the motor. The motor core consists of an outer stator, an inner rotor, and some other accessories. The core rotor needs to be assembled by riveting during processing to form a complete core rotor for subsequent installation and use.

[0003] However, the riveting devices currently used for motor core processing still have some defects in use. They cannot automatically feed the core during riveting, resulting in low processing efficiency.

[0004] A novel riveting device for motor cores is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a riveting device for motor cores to solve the problem mentioned in the background art of the inability to automatically transport the cores.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a riveting device for an electric motor core, comprising a base plate, a fixed frame fixedly connected to the rear end of the top of the base plate, a hydraulic cylinder fixedly connected to the top of the fixed frame, a pressure plate fixedly connected to the output end of the hydraulic cylinder through the top of the fixed frame, and a conveying mechanism for automatically transporting the core provided at the top of the base plate.

[0007] The conveying mechanism includes a turntable. The top of the base plate is movably connected to the turntable, and the top of the base plate is fixedly connected to a fixed seat. A first cavity is provided on the left side inside the fixed seat. A stepper motor is fixedly connected inside the first cavity. The output end of the stepper motor extends to the outside of the fixed seat and is fixedly connected to a drive gear. A gear ring is fixedly connected to the bottom of the turntable, and a limit ring is fixedly connected to the top of the turntable.

[0008] As a further technical solution of this utility model, the drive gear is meshed with the gear ring, and the limiting ring is movably connected to the fixed seat.

[0009] As a further technical solution of this utility model, positioning grooves are provided on both sides and both ends of the top of the turntable, and cylinders are provided at both ends of the positioning grooves. The output end of the cylinder extends into the interior of the positioning groove and is fixedly connected to an arc-shaped clamp.

[0010] As a further technical solution of this utility model, the two sets of arc-shaped clamps inside the positioning groove are arranged symmetrically, and the positioning groove is connected to the interior of the turntable.

[0011] As a further technical solution of this utility model, the fixed base is provided with a second cavity, and an electric cylinder is fixedly connected inside the second cavity. The output end of the electric cylinder passes through the front end of the fixed base and is fixedly connected to a push plate.

[0012] As a further technical solution of this utility model, the center line of the push plate and the center line of the fixed base are on the same vertical plane, and the center line of the push plate and the center line of the positioning groove are on the same vertical plane.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the riveting device for the motor core not only realizes automatic transportation of the core and quick positioning of the core, but also realizes automatic ejection of the core after riveting for easy material removal.

[0014] The system includes a turntable, a positioning groove, a first cavity, a stepper motor, a drive gear, a fixed seat, a gear ring, and a limit ring. During processing, the workpiece is positioned inside the positioning groove. Then, the stepper motor inside the first cavity is started to drive the drive gear to rotate. As the drive gear rotates, it drives the turntable to rotate through the gear ring. The turntable then drives the workpiece inside the positioning groove to rotate, moving the workpiece to the bottom of the pressure plate for rapid riveting. The fixed seat can limit the turntable to maintain concentric rotation through the limit ring, thus enabling automatic workpiece transport.

[0015] By setting up a positioning groove, arc-shaped clamping plates and cylinders, the iron core rotor is first assembled together and placed between two sets of arc-shaped clamping plates inside the positioning groove during processing. Then, the cylinders at both ends of the positioning groove are started at the same time. After the cylinders are started, they push the arc-shaped clamping plates to move. The two sets of arc-shaped clamping plates inside the positioning groove move towards the middle and fit against the outside of the workpiece, which can quickly position the workpiece to ensure the stability of the workpiece during riveting and achieve rapid workpiece positioning.

[0016] By setting up a positioning groove, push plate, fixed seat, second cavity and electric cylinder, after the workpiece inside the positioning groove is riveted, the positioning groove is driven to rotate to transport the workpiece to the top front position of the base plate, and the cylinder is activated to open the two sets of arc-shaped clamps. Then the electric cylinder inside the second cavity is activated, and the electric cylinder pushes the push plate to one end, which can push out the workpiece inside the positioning groove for easy material removal. This realizes that the workpiece can be automatically ejected after the riveting is completed. Attached Figure Description

The turntable 2 then drives the workpiece inside the positioning groove 3 to rotate, moving the workpiece to the bottom of the pressure plate 7 for quick riveting. The fixed seat 12 can limit the turntable 2 through the limit ring 14 to keep it rotating concentrically, thus realizing automatic workpiece transportation.

[0027] Positioning grooves 3 are provided on both sides and both ends of the top of the turntable 2. Cylinders 17 are provided at both ends of the positioning grooves 3.

[0029] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, during processing, the iron core rotor is first assembled together and placed between the two sets of arc-shaped clamping plates 4 inside the positioning groove 3.
