Description

Technical Field

[0001] The utility model relates to the technical field of stator and rotor core production equipment, and particularly relates to a pressure-holding and cooling device for pressing and heating a stator and rotor core for a new energy vehicle. Background Art

[0002] The stator core is a key component in a motor or generator and is located in the fixed part (stator) of the motor. Its main function is to provide a path to guide the magnetic flux and interact with the magnetic field generated by the rotor (rotating part), so as to generate electromagnetic induction in the armature winding and finally convert electrical energy and mechanical energy.

[0003] The stator core is usually composed of many thin layers of electrical steel sheets stacked together. During the manufacturing process, these steel sheets are precisely stacked and fixed together to form a cylindrical structure with notches in the middle for placing the stator windings.

[0004] During the production process of the stator core, it is necessary to perform pressure-holding and cooling treatment on the product after pressing and heating. The existing pressure-holding and cooling devices mainly rely on blowers and air ducts to blow normal-temperature air to cool the product. However, since the product has a certain height, the air blown out by the fixedly installed air ducts is difficult to completely cover the entire product, resulting in poor cooling efficiency and cooling effect of the product.

[0005] Therefore, there is an urgent need for a pressure-holding and cooling device for pressing and heating a stator and rotor core for a new energy vehicle with high cooling efficiency. Summary of the Invention

[0006] The purpose of the utility model is to overcome the above deficiencies and provide a pressure-holding and cooling device for pressing and heating a stator and rotor core for a new energy vehicle with high cooling efficiency.

A pressing mechanism is fixedly installed at the output end of the bottom of the servo cylinder. A stator fixture is arranged below the pressing mechanism. Support plates are movably installed on both sides of the stator fixture. Vertical rods are fixedly installed above both ends of the support plates. A cross bar is horizontally arranged at the top of the vertical rods. The cross bar is movably connected to the vertical rods through connecting blocks. A support rod is installed at the bottom of the cross bar. The support rod is movably connected to the cross bar through a connecting block. A support for fixing an air duct is fixedly arranged at the end of the support rod. The air duct is fixedly installed at the bottom of the support. A bottom plate is fixedly arranged at the bottom of the support plate. A push rod is movably installed at the bottom of the bottom plate. A limit ring is fixedly arranged at one end of the push rod. A connecting rod is movably installed inside the limit ring. The other end of the connecting rod is fixedly installed at the output end of a drive motor.

[0009] Preferably, the vertical rods, the cross bar and the support rods are all of round rod structures. Round holes and strip-shaped slots for installing the round rods are opened at both ends of the connecting block. The strip-shaped slot of the connecting block is tightened by bolts.

[0010] Preferably, the four air ducts on both sides of the stator fixture are distributed in an "X" shape.

[0011] Preferably, the bottom plates at the bottom of the support plates on both sides of the stator fixture are connected as a whole through push rods.

[0012] Preferably, rotating shafts are fixedly arranged at both ends of the support plate. The support plate is movably installed through the rotating shafts at both ends.

[0013] Preferably, the limit ring and the push rod are perpendicularly distributed. A groove for the connecting rod to slide is opened at the middle position of the limit ring. When the drive motor drives the connecting rod to rotate, the push rod is driven to do reciprocating linear motion by the cooperation of the connecting rod and the groove.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

At the same time, the four air ducts blow normal-temperature air to cool the four corners of the stator fixture, improving the cooling efficiency. And the cooling is carried out in two working positions, improving the cooling effect.

[0016] 2. The pressure-holding and cooling device for pressing and heating the stator and rotor cores of a new energy vehicle according to the present utility model realizes the up-and-down sweeping of the air duct by fixing rotating shafts at both ends of the support plate, movably installing the support plate through the rotating shafts at both ends, connecting the bottom plates at the bottoms of the support plates on both sides of the stator fixture into one body by push rods, and driving the push rods to perform reciprocating linear motion through a connecting rod and a limit ring of a driving motor, thereby driving the support plate to tilt left and right, improving the cooling efficiency and effect.
