Description

Technical Field

[0001] The utility model relates to the technical field of automobile cooling fan stators, in particular to a press-fitting device for an automobile cooling fan stator. Background Art

[0002] The stator of the car cooling fan is the key to the rotation of the car cooling fan. The stator is the stationary part of the motor or generator. The stator consists of three parts: the stator core, the stator winding and the frame. The stator is used to generate a rotating magnetic field. The core part of the stator needs to be pressed together with iron core sheets obtained by multi-layer die-casting.

[0003] The existing press-fitting device for the stator of an automobile cooling fan can press-fit multiple iron cores at one time, but cannot effectively ensure that the iron cores are completely in the same vertical plane. Slight deviations will cause errors in the iron cores, and slight errors will affect the rotation effect of the stator. After the press-fitting is completed, the existing press-fitting device for the stator of an automobile cooling fan needs to manually collect the assembled iron cores, which is rather troublesome. Therefore, in view of the above problems, a press-fitting device for the stator of an automobile cooling fan is proposed. Summary of the invention

[0010] Preferably, the number of the first limiting blocks is six, and they are evenly arranged on the surface of the limiting rod with the limiting rod as the center of the circle.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, by setting components such as a fixed seat, a limit groove, a limit rod, a first limit block, a press block, a second limit block, an extrusion block, a second hydraulic rod and a fixed block, firstly, the groove on the surface of the iron core piece is aligned with the first limit block on the surface of the limit rod, and then the iron core piece is sleeved on the limit rod under the limit of the first limit block, and this action is repeated until the height of the iron core piece is stacked to be flush with the limit rod, and then the second hydraulic rod is controlled by the external control module to drive the press block to punch downward, at this time, the second limit block will be engaged in the outer groove of the iron core piece, and the double fixation formed by the first limit block and the second limit block can prevent the iron core piece from rotating, and the limit block The positioning rod ensures that the iron core is completely vertical, and the second hydraulic rod drives the press block to punch downward until the fixed block enters the limiting groove. The fixed block and the limiting groove can prevent the press block from deviating during press fitting, which affects the quality of the iron core. When the press block is pressed down, the extrusion block squeezes a dent on the surface of the iron core. Under the action of the dent, the iron core is pressed and fitted more firmly, thereby solving the problem that the existing press-fitting device of the stator of the automobile cooling fan can press multiple iron cores at a time, but it cannot effectively ensure that the iron cores are completely in the same vertical plane. Slight deviations will cause errors in the iron core, and slight errors will affect the rotation effect of the stator.

[0013] 2. In the utility model, by setting components such as the motor, motor seat, support rod, bottom plate, guide plate, guide trough, baffle, collection box and collection trough, the control module controls the first hydraulic rod and the support plate to retract, leaving space for the rotation of the fixed seat, and the control module controls the motor to rotate, and the fixed seat and the iron core are driven by the motor to rotate 120 degrees. Under the action of gravity, the iron core slides from the limit rod and slides into the guide trough of the guide plate. Under the action of the slope of the guide plate, it slides from the guide trough to the collection trough, completing the collection of the iron core, thereby solving the problem that the existing press-fitting device of the stator of the automobile cooling fan needs to manually collect the assembled iron core after the press-fitting is completed, which is quite troublesome.
