Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, and in particular to a motor core clamping device. Background Technology

[0002] The motor core is a crucial component in an electric motor, primarily used to concentrate and guide the magnetic field generated by the electromagnetic coil. The core is typically made of soft magnetic materials, possessing good magnetic permeability and a certain level of mechanical strength to ensure the motor's stability during operation. The shape and size of the core vary depending on the type and application of the motor. Clamping devices within the core mainly serve to fix and support the internal magnetic materials, ensuring the integrity of the magnetic circuit and improving motor efficiency and performance. The core is usually constructed from stacked silicon steel sheets coated with insulating material. The use of clamping devices helps prevent vibration of the silicon steel sheets, reduces energy loss, and ensures the stability of the electromagnetic field.

[0003] Currently, most existing clamping devices only clamp and fix the iron core to the side wall during use, which cannot guarantee that the iron core will not be damaged due to vehicle bumps during transportation, thus affecting subsequent use. Therefore, the clamping devices need to be improved. Utility Model Content

Then, by sequentially activating an electric push rod and a miniature double-headed motor, the electric push rod drives clamping rings on both sides to clamp the motor core. Next, the miniature double-headed motor drives a threaded rod to rotate, which in turn moves a slider to the adjacent or opposite side. This movement of the slider clamps the motor core. The top cover and connecting column are then fixed with bolts. Finally, a hydraulic rod drives a stop block at the top and the top cover to reinforce the motor core. When disassembly of the motor core is required, the bolts are removed, allowing the top cover to be removed.

[0005] A motor core clamping device according to an embodiment of the present invention includes a base plate. Through slots are provided on both the front and rear sides of the top center of the base plate. A miniature double-headed motor is connected through and fixedly connected to the center of the interior of the base plate. A threaded rod is connected through and fixedly connected to the output end of each miniature double-headed motor. A slider is threadedly connected to the outer diameter of each threaded rod. A hydraulic rod is fixedly connected to the center of the top of the base plate. A connecting column is fixedly connected to the output end of the hydraulic rod. One end of a uniformly distributed connecting plate is fixedly connected to the outer diameter of the connecting column. A stop block is fixedly connected to the other end of each connecting plate. A motor core is disposed at the center of the top of the base plate.

[0006] Furthermore, each of the sliders is fixedly connected to a second clamping ring, and each of the second clamping rings has a slot through it on an adjacent side.

[0007] Furthermore, the inner wall of the motor core is provided with and slidably connected to several abutments, the outer wall of the motor core is provided with a protective layer, and the outer wall of the protective layer is fixedly connected with several locking blocks.

[0008] Furthermore, a support sleeve is fixedly connected to the top of the base plate, and electric push rods are fixedly connected to both the left and right sides of the inner wall of the support sleeve.

[0009] Furthermore, each of the output ends of the electric push rod is connected to a clamping ring, and each of the adjacent sides of the clamping ring is provided with a slot.

[0010] Furthermore, each of the card slots is fixedly connected to a pressure sensor, and each of the card slots is provided with and slidably connected to a card block.

[0011] Furthermore, a top cover is provided at the top of the motor core, and several fixing bolts are threaded through and connected to the middle of the top of the top cover.

[0012] Furthermore, the top of the connecting column is threaded with several fixing bolts, and the connecting column and the top cover are threadedly connected by the fixing bolts.

[0013] The beneficial effects of this utility model are:

[0014] When clamping the motor core is required, first place the motor core at the top center of the base plate. Then, activate the electric push rod and the miniature double-headed motor in sequence. The electric push rod drives the clamping rings on both sides to clamp the motor core. Next, the miniature double-headed motor drives the threaded rod to rotate. The rotation of the threaded rod can move the slider to the adjacent or opposite side. The movement of the slider can drive the clamping rings to clamp the motor core. Then, fix the top cover and connecting column with fixing bolts. Then, the hydraulic rod drives the top block and top cover to reinforce the motor core. When it is necessary to disassemble the motor core, remove the fixing bolts and the top cover can be removed.
