[0002] Magnetization is to magnetize magnetic materials or increase the magnetism of magnets with insufficient magnetism. Generally, the magnetic object to be magnetized is placed in the magnetic field formed by a coil through which direct current passes.
[0003] When magnetizing the motor, the internal structure of the motor is relatively complex, and ordinary magnetizing tools cannot meet the magnetizing requirements of the starter motor, and they cannot magnetize the starter motor evenly, which leads to a greater impact on the subsequent use of the starter motor after magnetization.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new energy vehicle starter motor magnetizing tooling, comprising a base plate, four supporting legs are fixedly installed at the bottom of the base plate, the four supporting legs are arranged in a rectangular array at the bottom of the base plate, a controller is arranged on the upper end surface of the base plate, a placement plate is fixedly installed at the middle position of the upper surface of the base plate, a starter motor body is placed on the placement plate, vertical plates are fixedly installed at both sides of the upper surface of the base plate, slide grooves are provided on the inner surfaces of the vertical plates, a driving motor is fixedly installed at the top of the vertical plates, the driving motor is electrically connected to the controller, a threaded rod is fixedly installed at the output end of the driving motor, and the threaded rod passes through the top of the vertical plate and extends into the slide groove.
[0006] By adopting the above technical solution, the driving motor is controlled by a controller. When the driving motor is turned on, it will drive the threaded rod installed on its output end to rotate. Because the horizontal plate is arranged in the slide groove opened in the vertical plate, and the through holes opened at both ends of the vertical plate are inserted with threaded rods, when the threaded rod rotates, it will drive the horizontal plate to move up and down in the slide groove, so that the magnetizing cavity on the horizontal plate will wrap the starter motor body, thereby facilitating its magnetization.
[0007] Preferably, a horizontal plate is arranged inside the vertical plate, through holes are opened on both side end faces of the horizontal plate, threaded rods penetrate the through holes, and a magnetizing cavity is fixedly installed at the middle position of the horizontal plate.
[0008] With the above technical solution, since the horizontal plate is arranged in the slide groove provided in the vertical plate, and threaded rods are inserted into the through holes provided at both ends of the vertical plate, when the threaded rods rotate, the horizontal plate is driven to move up and down in the slide groove.
[0009] Preferably, a magnetic pole coil is arranged inside the magnetizing cavity, a plurality of iron cores in a circular array are arranged inside the magnetic pole coil, an external current meter is arranged at the top of the magnetizing cavity, and the external current meter passes through the magnetizing cavity and extends into the magnetizing cavity to be connected with the magnetic pole coil.
[0010] By adopting the above technical solution, electricity is supplied to the pole coil through an external current meter, and then when the pole coil is energized, a magnetic field is generated between the pole coil and the iron core arranged inside it, so as to magnetize the starter motor body. At the same time, after the starter motor body is wrapped by the magnetizing cavity, it can be magnetized more evenly, and the quality of the magnetization of the motor can be better guaranteed.
[0011] Preferably, a groove is provided at the bottom of the outer surface of the magnetizing cavity.
[0012] With the above technical solution, since the diameter of the groove at the bottom of the outer surface of the magnetizing cavity is larger than that of the push rod, when the magnetizing cavity wraps the starter motor, the push rod will not affect the magnetizing cavity.
[0013] Preferably, mounting plates are fixedly mounted on both front and rear ends of the upper surface of the base plate, a push rod is fixedly mounted on the inner end surface of the mounting plate, the push rod is electrically connected to the controller, and a clamp is fixedly mounted on the pushing end of the push rod.
[0014] By adopting the above technical solution, the push rod installed on the inner end surface of the mounting plate is controlled by a controller, and then when the push rods installed at the front and rear ends of the base plate are controlled, the clamping plates installed at their inner ends are driven to move inward, so as to clamp the starter motor body placed on the placement plate, so that the starter motor body can remain stable during magnetization.
[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] 1. The magnetizing tooling of the starter motor of the new energy vehicle is energized between the magnetic pole coil through an external current meter. Then, when the magnetic pole coil is energized, a magnetic field is generated between the magnetic pole coil and the iron core arranged inside it, so as to magnetize the main body of the starter motor. At the same time, the main body of the starter motor can be magnetized more evenly after being wrapped by the magnetizing cavity, and the quality of the magnetization of the motor can be better guaranteed.
[0017] 2. The magnetizing tooling of the starter motor of the new energy vehicle controls the push rod installed on the inner end surface of the mounting plate through the controller. Then, when the push rods installed at the front and rear ends of the bottom plate are controlled, the clamping plates installed at the inner ends thereof will be driven to move inward, so as to clamp the starter motor body placed on the placement plate, so that the starter motor body can remain stable during magnetization.
