Description

An Improved Ventilation Slot Plate

technical field

The utility model belongs to the field of motor and generator ventilation slot plate manufacture, and relates to an improved ventilation slot plate.

Background technique

In the production and manufacture of motors, since the motor rotates to generate heat, during the production process of the motor iron core, according to the requirements of the heat dissipated by the motor rotation, the laminated punching pieces at intervals of a certain length need to be ventilated with ventilation slots and I-shaped. The slots form a certain number of air passages to dissipate heat. Therefore, the I-shaped ventilation slot on the ventilation slot plate not only needs to bear the radial pressure of the laminated punching sheet, but also bears part of the axial force during the rotation of the iron core, so as to ensure that the work can be done during the rotation of the iron core. The font-shaped ventilation slots do not fall off.

In the previous production, no matter what welding process was used, the I-beam ventilation slots had to be fixed by means of tooling. Since the positions and materials of the tooling and the I-beam ventilation slots were relatively close, deviations were likely to occur during welding. The tooling is welded together with the I-beam ventilation groove and is not easy to remove. In addition, due to the deviation of the tooling itself, there are large errors in the verticality and quality of the I-beam ventilation slots during welding.

Utility model content

The problem to be solved by the utility model is to fix the I-steel ventilation slots on the ventilation slots by using tooling in the above-mentioned prior art. There is a deviation, which causes a deviation in the installation position of the I-beam ventilation slot, which affects the lack of heat dissipation effect, and provides an improved ventilation slot plate that is convenient for installation and welding and has a good heat dissipation effect.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

An improved ventilation slot plate, including a ventilation slot plate body, the ventilation slot plate body includes a slot plate tooth portion and a slot plate yoke portion, and the slot plate yoke is provided with a boss group on the center line of the slot plate tooth portion, and the convex The table set includes a circular boss and two rectangular bosses arranged in a character. The size of the circular boss matches the size of the preset groove on the I-shaped ventilation slot, and the two rectangular bosses The distance between them is adapted to the width of the I-shaped ventilation slot, and the distance between the circular boss and the two rectangular bosses is adapted to the length of the I-shaped ventilation slot; the I-shaped ventilation slot The groove at one end is clipped into the circular boss, and the other end of the I-shaped ventilation slot is clipped between the two rectangular bosses to be positioned and welded with the ventilation slot plate body.

The circular boss is close to the tooth root of the tooth part of the slot plate, and the two rectangular bosses are arranged symmetrically on both sides of the centerline of the tooth part of the slot plate.

Ventilation holes are evenly distributed on the annular surface of the yoke of the slot plate around its shaft hole. When the centerline of the tooth portion of the slot plate passes through the vent hole, the corresponding two rectangular bosses are located on the radially outer edge of the vent hole; When the center line of the plate teeth avoids the air hole, the corresponding two rectangular bosses are located on the edge of the shaft hole of the slot plate yoke.

The I-shaped ventilation slots have two sizes, one is adapted to the set of bosses whose symmetry axis runs through the air hole, and the other is adapted to the set of bosses whose symmetry axis avoids the air hole.

The main body of the ventilation slot plate and the I-shaped ventilation slot piece are fixedly connected by spot welding.

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

1. Use the boss group to position and fix the I-steel ventilation slots, which can ensure that the centerline of the I-steel ventilation slots is aligned with the centerline of the teeth of the slot plate.

2. Utilizing the cooperation between the circular boss and the I-steel ventilation slot not only ensures the spot welding position during direct spot welding, but also prevents the teeth of the slot plate from falling off.

3. Since the circular boss and two rectangular bosses directly ensure the verticality and position of the I-beam ventilation slots, the use of tooling molds is reduced, the cost of molds for enterprises is reduced, and the efficiency of on-site production is improved.

detailed description

Now in conjunction with accompanying drawing, the utility model is described in further detail. These drawings are all simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the configurations related to the utility model.

As shown in Figure 1, an improved ventilation slot plate includes a ventilation slot plate body, the ventilation slot plate body includes a slot plate tooth portion 1 and a slot plate yoke portion 2, and the slot plate yoke portion 2 is located at the center of the slot plate tooth portion 1 Boss groups 3 are arranged on the line, and the boss group 3 includes a circular boss 4 and two rectangular bosses 5 arranged in a character. The size of the circular boss 4 is the same as that of the I-shaped ventilation slot 6. The size of the preset groove 7 on the top is adapted, the distance between the two rectangular bosses 5 is adapted to the width of the I-shaped ventilation slot 6, and the distance between the circular boss 4 and the two rectangular bosses 5 The distance between them matches the length of the I-shaped ventilation slot 6; the groove 7 at one end of the I-shaped ventilation slot 6 snaps into the circular boss 4, and the other end of the I-shaped ventilation slot 6 snaps into two Between the two rectangular bosses 5, it is positioned and welded with the main body of the ventilation slot plate.
