Description

Technical Field

[0001] This utility model relates to the field of rotor core technology, and in particular to a rotor core shaping and testing bench. Background Technology

[0002] The rotor core of an electric motor is made of laminated silicon steel sheets (laminated sheets). These silicon steel sheets are typically stamped on a press using a progressive die. After the rotor core is assembled, the lamination between adjacent silicon steel sheets may not be tight, resulting in a significant positive height deviation. This loose lamination can cause noise in the motor and reduce the magnetic properties of the core. Furthermore, an excessively high overall core height can affect the assembly quality of the motor. Therefore, it is necessary to inspect the stamped and shaped rotor core.

[0003] A rotor core compaction and testing integrated machine, disclosed in CN214850894U, includes a frame and a top-pressure cylinder, a guide pressure assembly, and a worktable arranged sequentially from top to bottom on the frame. A positioning mold for the rotor core is mounted on the worktable, and an ejection mechanism for ejecting the compacted rotor core from the positioning mold is located below the worktable. The guide pressure assembly includes several guide columns erected on the frame, a lifting plate movable on the guide columns, a shaping pressure head fixed at the lower center of the lifting plate, and a pressure sensor fixed at the upper center of the lifting plate. Existing integrated machines mostly rely on manual labor to place the rotor core to be compacted onto a stamping table for testing. After testing, the stamped core is removed before a new core is placed in. This method is inefficient for large-scale rotor core testing. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where, after the stamping and testing of the iron core is completed, the stamped and tested iron core is removed and a new iron core to be tested is placed in, resulting in low work efficiency when stamping and testing large batches of iron cores. The invention provides a rotor iron core shaping and testing bench that can automatically and synchronously perform loading and unloading, thereby speeding up the work efficiency.

[0005] To achieve the above objectives, this utility model provides a rotor core shaping and testing bench, including a base plate, a compaction testing bench on the base plate, a clamping assembly on one side of the compaction testing bench, a feeding assembly on another side of the compaction testing bench, and a discharge mechanism on the other side of the compaction testing bench. A transfer assembly is provided between the discharge mechanism and the clamping assembly. The clamping assembly includes a mounting plate, a first electric gripper and a second electric gripper are connected to the mounting plate, a movable plate is provided below the mounting plate, the bottom of the movable plate is slidably connected to a slide rail, and one side of the movable plate is connected to an electric telescopic rod through a connecting plate.

[0006] As a further description of the above technical solution: the feeding assembly includes a feeding conveyor frame, a feeding belt is provided on one side of the feeding conveyor frame, and a first driving member is provided on the side of the feeding belt.

[0007] As a further description of the above technical solution: the discharge mechanism includes a discharge conveyor frame, a discharge belt is provided on one side of the discharge conveyor frame, a second driving component is provided on the side of the discharge conveyor frame, and a waste recycling box is provided on one side of the discharge conveyor frame.

[0008] As a further description of the above technical solution: the material transfer assembly includes a material transfer gripper, a rotating plate is provided below the material transfer gripper, the rotating plate is connected to the driven wheel through a rotating shaft, the driven wheel is connected to the drive wheel through a transmission belt, the drive wheel is connected to the output end of the drive motor, and the rotating shaft is mounted on the base plate through a bearing seat.

[0009] As a further description of the above technical solution: an electric lifting rod is provided between the mounting plate and the movable plate, and limiting slide rods that are slidably connected to the mounting plate are provided on both sides of the electric lifting rod.

[0010] As a further description of the above technical solution: a telescopic component is connected between the material transfer gripper and the rotating plate.

[0011] As a further description of the above technical solution: a control box and a control panel are provided on one side of the base plate, and a transfer plate is provided between the material discharge mechanism and the clamping assembly.

[0012] The above technical solution has the following advantages or beneficial effects:

[0013] This invention uses a first and a second electric gripper to precisely hold the rotor core on the feeding assembly and the compaction testing table. The gripping and releasing actions are electrically controlled, ensuring stability and reliability. A sliding connection between the bottom of a movable plate and a slide rail allows the movable plate to move under the drive of an electric telescopic rod. The connecting plate slides smoothly on the slide rail, thereby moving the mounting plate and grippers horizontally. This accurately delivers the iron core held by the first and second electric grippers to the compaction testing table and the material transfer assembly, achieving automatic and synchronized feeding and unloading, thus increasing work efficiency.

[0022] In the description of this utility model, it should be noted that the terms "vertical", "up", "down", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] like Figure 1-5 As shown, the rotor core shaping and testing bench of this utility model includes a base plate 1, a compaction testing bench 2 is provided on the base plate 1, a clamping assembly 3 is provided on one side of the compaction testing bench 2, a feeding assembly 4 is provided on one side of the compaction testing bench 2, a discharge mechanism 5 is provided on the other side of the compaction testing bench 2, and a transfer assembly 6 is provided between the discharge mechanism 5 and the clamping assembly 3; the clamping assembly 3 includes a mounting plate 31, a first electric gripper 32 and a second electric gripper 33 are connected to the mounting plate 31, a moving plate 34 is provided below the mounting plate 31, the bottom of the moving plate 34 is slidably connected to the slide rail 35, and one side of the moving plate 34 is connected to the electric telescopic rod 37 through a connecting plate 36.

[0025] In the technical solution of this utility model, the rotor core to be compacted and tested can be placed on the compaction testing table 2. The first electric gripper 32 and the second electric gripper 33 can accurately hold the feeding component 4 and the rotor core on the compaction testing table 2. The clamping and releasing actions are realized by electric control to ensure the stability and reliability of clamping. The bottom of the moving plate 34 is slidably connected to the slide rail 35, so that the moving plate 34 can move under the drive of the electric telescopic rod 37. The connecting plate 36 slides smoothly on the slide rail 35, thereby driving the mounting plate 31 and the gripper to move horizontally. The iron core held on the first electric gripper 32 and the second electric gripper 33 is accurately delivered to the compaction testing table 2 and the material transfer component 6, realizing automatic synchronous loading and unloading, and speeding up the work efficiency.

[0026] An electric lifting rod 38 is provided between the mounting plate 31 and the movable plate 34. Limiting slide rods 39 are provided on both sides of the electric lifting rod 38 and are slidably connected to the mounting plate 31. The electric lifting rod 38 can drive the mounting plate 31 to rise and fall in the vertical direction, realizing the clamping and placement operations at different height positions. Combined with horizontal movement, it enhances the flexibility and applicability of the clamping assembly 3. When the electric lifting rod 38 is in operation, the limiting slide rods 39 provide guidance and limit for the mounting plate 31, preventing the mounting plate 31 from deviating during the lifting process and ensuring the accuracy of the clamping and placement operations.

[0027] Specifically, the compaction testing table 2 is equipped with compaction components and testing components, which is existing technology. The control system drives the top pressure cylinder to shape and pressurize the end face of the rotor core. The pressure sensor monitors the pressure of the shaping and pressing, ensuring that the pressure is controlled within a preset value and maintained for a period of time. After the pressure holding time ends, the pressure head rises, and the control system controls the top pressure cylinder to apply pressure again according to the preset detection pressure. Then, the vertical displacement sensor detects the position of the lifting plate and calculates the thickness of the rotor core. When the thickness of the rotor core is not up to standard, the control system issues an alarm to remind the operator to handle the situation.

[0028] like Figure 1 and Figure 2 As shown, the feeding assembly 4 includes a feeding conveyor frame 41, a feeding belt 42 is provided on one side of the feeding conveyor frame 41, and a first driving member 43 is provided on the side of the feeding belt 42; the feeding belt 42 operates under the drive of the first driving member 43 to realize the continuous feeding of the rotor core, and the core is transported from the initial position to a position close to the clamping assembly 3 so that the clamping assembly 3 can clamp it, thus ensuring the continuity and stability of the feeding process and improving work efficiency.

[0029] like Figure 1 and Figure 2 As shown, the discharge mechanism 5 includes a discharge conveyor frame 51, a discharge belt 52 on one side of the discharge conveyor frame 51, a second driving component 53 on the side of the discharge conveyor frame 51, and a waste recycling box 54 on one side of the discharge conveyor frame 51. Driven by the second driving component 53, the discharge belt 52 transports the tested iron cores from the compaction testing table 2 to the subsequent processing position. The waste recycling box 54 is located on one side of the discharge conveyor frame 51 and is used to collect the waste iron cores that are judged to be unqualified during the testing process. This realizes the automatic classification of qualified products and waste products, which facilitates subsequent processing.

[0030] Specifically, both the first driving component 43 and the second driving component 53 are driven by a motor-driven drive shaft, and the first driving component 43 and the second driving component 53 drive the feeding belt 42 and the discharging belt 52 for conveying.

[0031] like Figure 1 and Figure 4 As shown, the transfer assembly 6 includes a transfer gripper 61, and a rotating plate 62 is arranged below the transfer gripper 61. The rotating plate 62 is connected to the driven wheel 64 through a rotating shaft 63. The driven wheel 64 is connected to the drive wheel 65 through a transmission belt. The drive wheel 65 is connected to the output end of the drive motor 66. The rotating shaft 63 is mounted on the base plate 1 through a bearing seat. The transfer gripper 61 can hold the iron core on the transfer plate 9. The rotating plate 62 rotates under the action of the drive motor 66 driving the rotating shaft 63 to rotate through the drive wheel 65, the transmission belt and the driven wheel 64, thereby driving the transfer gripper 61 to rotate at different angles, transferring the gripped iron core from the transfer plate 9 to the discharge belt 52 or the waste recycling box 54, realizing the automated classification and collection of the rotor, and ensuring the efficient transfer of the iron core between different workstations.

[0032] Specifically, a telescopic component 67 is connected between the transfer gripper 61 and the rotating plate 62; the telescopic component 67 enables the telescopic movement, adjusts the distance from the iron core, and ensures stable gripping.

[0033] Among them, the telescopic component 67 can be an electric telescopic rod.

[0034] like Figure 1and Figure 2 As shown, a control box 7 and a control panel 8 are provided on one side of the base plate 1, and a transfer plate 9 is provided between the discharge mechanism 5 and the clamping assembly 3. Various electrical control components are integrated inside the control box 7 to uniformly control all electric components of the entire frame, coordinate the actions of each component according to the preset program, and ensure the smooth progress of the testing process. The control panel 8 provides a human-machine interface for operators, who can set parameters, start and stop the equipment operation, etc. through the control panel 8, which facilitates the operation and monitoring of the frame.

[0035] Specifically, the transfer plate 9 is set between the discharge mechanism 5 and the clamping assembly 3, providing a temporary placement and transition platform for the transfer assembly 6 to transfer the iron core, ensuring the stability and accuracy of the iron core transfer process.

[0036] Working principle: The rotor core to be compacted and tested can be placed on the compaction testing table 2. The first electric gripper 32 and the second electric gripper 33 can accurately hold the rotor core on the feeding assembly 4 and the compaction testing table 2. The clamping and releasing actions are realized by electric control to ensure the stability and reliability of clamping. The bottom of the moving plate 34 is slidably connected to the slide rail 35, so that the moving plate 34 can move under the drive of the electric telescopic rod 37. The connecting plate 36 slides smoothly on the slide rail 35, thereby driving the mounting plate 31 and the gripper to move horizontally. The iron core held by the first electric gripper 32 and the second electric gripper 33 is accurately delivered to the compaction testing table 2 and the material transfer assembly 6, realizing automatic synchronous loading and unloading, and speeding up the work efficiency.
