Description

Technical Field

[0001] This utility model belongs to the field of motor processing technology, specifically a shaping device for processing motor stator and rotor cores. Background Technology

[0002] In the process of motor manufacturing, the processing quality of the stator and rotor cores plays a crucial role in the performance of the motor. In the existing technology, the stator and rotor cores are usually made of multiple layers of metal sheets laminated and bonded together. In order to ensure their dimensional accuracy, shape accuracy and the tightness of the internal metal sheets, a shaping device is usually required to shape them during the processing of the motor stator and rotor cores.

[0003] In the existing technology, there is a shaping device for processing motor stator and rotor iron cores with announcement number CN217769801U. This application uses an electric lifting cylinder as a power source to provide downward pressure during shaping, and at the same time obtains the thickness data of the material iron core through the signal fed back by the electric lifting cylinder, thus achieving two goals at once and completing shaping and thickness measurement simultaneously. However, in use, the rotor core is usually clamped by a clamping assembly to prevent positional displacement during shaping. However, the height of the clamping plate cannot be adjusted, making it unable to adapt to rotor cores of different thicknesses. This results in uneven distribution of clamping force, causing misalignment or deformation of the core laminations, which reduces the applicability of the device and affects the shaping effect. To address this, we provide a shaping device for machining motor stator and rotor cores. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problems of clamping rotor cores of different thicknesses and precisely extruding and forming the clamped rotor cores, a shaping device for machining motor stator and rotor cores is proposed.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A shaping device for machining motor stator and rotor cores, comprising: The processing table has a circular groove at its upper end, a limiting groove on the inner side wall of the circular groove, a rotating rod connected to the inside of the limiting groove by a limiting ring, a turntable fixedly installed at the upper end of the rotating rod, a stroke groove at the upper end of the turntable, and a frame installed on one side of the processing table by bolts.

[0006] Preferred options also include: A limiting component, disposed on one side of the turntable, is used to limit the rotor core.

[0007] Preferably, the limiting component includes: A circular hole is provided on one side of the turntable, and a transmission rod is provided inside the circular hole. A rotating ring is fixedly installed at one end of the transmission rod, and a double-acting lead screw is fixedly installed at the other end of the transmission rod. One end of the double-acting lead screw is set in the stroke groove through a bearing.

[0008] Preferably, the surface of the bidirectional lead screw is threadedly connected to a threaded block through a threaded hole, the threaded block is partially adapted to the stroke groove, and a clamping plate is fixedly installed on the upper end of the threaded block.

[0009] Preferably, the clamping plate has a square hole inside, and the front and back of the clamping plate have first threaded holes, with fixing bolts threaded inside the first threaded holes.

[0010] Preferably, the surface of the fixing bolt is threadedly connected to a movable clamping plate through a second threaded hole, and the movable clamping plate is partially adapted to the square hole.

[0011] Preferred options also include: A rotor core pressing assembly is installed at the upper end of a frame and is used to extrude and form the rotor core.

[0012] Preferably, the rotor core pressing assembly includes: A hydraulic cylinder is bolted to the upper end of the frame. One end of the hydraulic cylinder is provided with a piston rod. A connecting plate is fixedly installed at one end of the piston rod, and a reinforcing rod is provided inside the connecting plate. A pressing plate is fixedly installed at the lower end of the connecting plate.

[0013] The beneficial effects of this utility model are: The limiting component of this utility model releases the restriction on the movable clamping plate by placing the rotor core on the turntable and then rotating the fixing bolt. The movable clamping plate is then pulled to move within the square hole. When the movable clamping plate reaches an appropriate height, the fixing bolt is rotated to restrict the movable clamping plate. Subsequently, the rotating ring drives the transmission rod and the double-acting screw to rotate. The rotation of the double-acting screw drives the threaded block and the clamping plate to move. Finally, the clamping plate drives the movable clamping plate to move, clamping the rotor core. This facilitates the clamping of rotor cores of different thicknesses and expands the applicability of the device.

[0014] The rotor core pressing assembly of this invention uses a hydraulic cylinder to move a piston rod, which in turn moves a connecting plate, which in turn moves an extrusion plate. This process precisely extrudes and shapes the clamped rotor core, effectively eliminating gaps between the core laminations. Attached Figure Description

[0018] Specific implementation examples are given below.

[0019] Example 1: Please see Figures 1 to 5 This utility model provides a shaping device for machining motor stator and rotor cores, comprising: The processing table 1 has a circular groove 2 at its upper end and a limiting groove 3 on its inner side wall. A rotating rod is connected to the inside of the limiting groove 3 through a limiting ring 4. A turntable 5 is fixedly installed at the upper end of the rotating rod and has a stroke groove at its upper end. A frame 6 is bolted to one side of the processing table 1. A limiting component 7 is set on one side of the turntable 5 to limit the rotor core. A rotor core pressing component 8 is installed at the upper end of the frame 6 to extrude and form the rotor core.

[0020] In this embodiment, the rotor core is first placed on the turntable 5, and the limiting component 7 is used to clamp rotor cores of different thicknesses, thereby improving the applicability of the device. Then, the rotor core pressing component 8 is used to precisely extrude and form the clamped rotor core, effectively eliminating the gaps between the core laminations.

[0021] Example 2: Based on Embodiment 1, the limiting component 7 is further disclosed.

A transmission rod 701 is installed inside the circular hole. A rotating ring 702 is fixedly installed at one end of the transmission rod 701, and a double-acting screw 703 is fixedly installed at the other end of the transmission rod 701. One end of the double-acting screw 703 is set in the stroke groove through a bearing. A threaded block 704 is threadedly connected to the surface of the double-acting screw 703 through a threaded hole. The threaded block 704 is partially adapted to the stroke groove. A clamping plate 705 is fixedly installed at the upper end of the threaded block 704. A square hole 706 is provided inside the clamping plate 705.

[0023] In this embodiment, the rotor core is placed on the turntable 5, and then the fixing bolt 708 is rotated to release the restriction on the movable clamping plate 710. Subsequently, the movable clamping plate 710 is pulled to move within the square hole 706. When the movable clamping plate 710 moves to an appropriate height, the fixing bolt 708 is rotated to restrict the movable clamping plate 710. Then, the rotating ring 702 drives the transmission rod 701 and the double-acting screw 703 to rotate. The rotation of the double-acting screw 703 drives the threaded block 704 and the clamping plate 705 to move. Finally, the clamping plate 705 drives the movable clamping plate 710 to move, clamping the rotor core.

This achieves the effect of precisely extruding and forming the clamped rotor core, effectively eliminating the gaps between the core laminations.
