Description

Technical Field

[0001] The utility model relates to the technical field of stator and rotor core production equipment, in particular to an automatic oil spraying device for pressing and heating stator and rotor cores for new energy vehicles. Background Art

[0002] The stator core is a key component in an electric motor or generator. It 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), thereby generating electromagnetic induction in the armature winding and ultimately converting electrical energy into mechanical energy.

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

[0004] Oil injection is the process before the pressing and heating process, and is one of the important processes in the production of stator cores. Oil injection makes the surface of the stator fixture more lubricated, which facilitates the installation and disassembly of the product. The oil nozzle of the existing automatic oil injection device is installed on the oil injection cover and rises and falls with the oil injection cover. The oil nozzle cannot be raised and lowered independently, which may easily lead to insufficient coverage of the oil injection and low oil injection efficiency.

[0005] Therefore, there is an urgent need for an automatic oil injection device for compressing and heating the stator and rotor cores of new energy vehicles with high oil injection efficiency and wide coverage. Summary of the invention

[0006] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide an automatic oil injection device for compressing and heating the stator and rotor cores of new energy vehicles with high oil injection efficiency and wide coverage.

[0007] The purpose of the utility model is achieved in this way:

[0008] An automatic oil spraying device for compacting and heating the stator and rotor cores of new energy vehicles comprises a frame, a first lifting cylinder is fixedly mounted on the outer wall of the frame, an oil spraying hood is mounted on the output end of the top of the first lifting cylinder, a support plate fixedly mounted on the outer wall of the oil spraying hood and connected to the output end of the first lifting cylinder is fixedly mounted, a slide rail is fixedly mounted on the inner wall of the oil spraying hood, a second lifting cylinder is also fixedly mounted on the inner wall of one side of the oil spraying hood, a base is fixedly mounted on the output end of the bottom of the second lifting cylinder, the base is slidably connected to the slide rail, and a receiving member is fixedly mounted in the middle position of the base. A collecting pipe, a gear ring is installed at the bottom of the base, and the gear ring is movably connected to the base through a bearing fixed at the top, a driving motor is fixedly installed on the upper side of one side of the base, and a driving gear for driving the gear ring to rotate is fixedly installed on the output end of the bottom of the driving motor, a support plate is fixedly installed at the bottom of the gear ring, top mounting plates are fixedly installed on the outer walls on both sides of the support plate, and side mounting plates are fixedly installed on the outer walls on the other two sides of the support plate, oil nozzles are fixedly installed on the outer walls of the top mounting plate and the side mounting plates, and a stator fixture is arranged below the oil spray hood.

[0009] Preferably, the oil spray hood is a cylindrical structure with a rectangular top view, and chamfers are provided at four right angles of the oil spray hood, and the slide rail is installed on the inner wall of the chamfered portion.

[0010] Preferably, the top mounting plate is a plate-shaped structure having a rectangular top view, and the fuel injector is fixedly mounted on the bottom of the top mounting plate.

[0011] Preferably, the side mounting plate is a plate-like structure having an inverted "L" shape in side view, and the fuel injector is fixedly mounted on the outer wall at the bottom of the side mounting plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model is an automatic oil spraying device for compressing and heating the stator and rotor cores of new energy vehicles. By installing a slide rail in the oil spraying cover, the base is guided, and the second lifting cylinder pushes the base to slide up and down along the slide rail, thereby driving the oil spray nozzles on the top mounting plate and the side mounting plate to move up and down, increasing the coverage of the oil spraying and making the oil spraying more comprehensive. At the same time, the collection pipe moves up and down with the oil spray nozzle, which has a good collection effect and prevents leakage.

[0014] 2. The utility model is an automatic oil injection device for compacting and heating the stator and rotor cores for new energy vehicles. A driving motor is installed on the base. The driving motor drives the gear ring at the bottom of the base to rotate through the driving gear, thereby driving the oil injection nozzle to rotate to fully spray the surface of the stator fixture. In addition, since the top mounting plate is arranged on both sides of the support plate and the side mounting plates are arranged on the other two sides of the support plate, the distribution range of the oil injection nozzle is increased, and at the same time, the angle required for the oil injection nozzle to rotate during oil injection is reduced, thereby improving the oil injection efficiency.
