Abstract
Description
Technical Field
[0001] This utility model belongs to the field of motor manufacturing technology, specifically relating to a motor core testing bracket. Background Technology
[0002] After the motor core completes wiring and welding processes, its surface and welded ends need to be inspected. During inspection, the core is placed horizontally on a bracket and rotated. At this point, the core and bracket are in a rolling connection, and the operator inspects the surface and welded ends sequentially around the circumference of the core. To prevent warping during subsequent operation, some cores use multiple bolts to fix the silicon steel sheets, resulting in a non-circular outer surface with multiple protrusions along the circumference. When inspecting these cores, the operator needs to lift the core when the protrusions roll into contact with the bracket. However, if the operator is slightly careless during this process, the circumference of the core can easily collide with the bracket, causing damage. To address this problem, a motor core inspection bracket is proposed. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0027] The following describes in detail, with reference to the accompanying drawings, the motor core testing bracket of this utility model.
[0028] like Figures 1-3As shown, the motor core testing bracket according to an embodiment of the present utility model includes: a base frame 1 and two rollers 2; the two rollers 2 are spaced apart on the base frame 1, the rollers 2 are movably connected to the base frame 1, and a groove 21 is formed on the circumferential surface of the rollers 2, the groove 21 is parallel to the central axis of the rollers 2, the two rollers 2 are used to support the core, and the groove 21 is used to embed the protrusion on the circumferential surface of the core.
[0029] In this embodiment, the distance between the two rollers 2 is no greater than the distance between the iron cores. The central axis of the rollers 2 is parallel to the central axis of the iron core. The iron core is placed on the two rollers 2, and during placement, the protrusions on the iron core are embedded in their corresponding grooves 21. Then, the iron core is manually rotated to make the iron core roll and connect with the two rollers 2, so that the rollers 2 can support the iron core. During this process, the grooves 21 prevent the protrusions of the iron core from contacting the outer surface of the rollers 2, thus ensuring the stability of the contact between the iron core and the outer surface of the rollers 2 when the iron core rotates, avoiding the action of lifting the iron core, and protecting the integrity of the outer surface of the iron core.
[0030] The number of grooves 21 is multiple, and multiple grooves 21 are spaced apart along the circumferential direction of the roller 2.
[0031] In this embodiment, the number of grooves 21 is twice the number of protrusions on the iron core. Taking three protrusions on the iron core as an example, the number of grooves 21 on the roller 2 is six. When placing the iron core, two of the protrusions on the iron core are respectively embedded into the grooves 21 of the two rollers 2. Therefore, the protrusions always engage with the grooves 21 during rotation, ensuring the stability of the contact between the outer surface of the iron core and the outer surface of the roller 2.
[0032] The roller 2 has guide rods 22 connected to the bearings at both ends, and the guide rods 22 are fixedly connected to the base frame 1.
[0033] In this embodiment, the length of the guide rod 22 can be longer than the length of the roller 2, so that the roller 2 is sleeved on the guide rod 22. At this time, the guide rod 22 can support the roller 2. The roller 2 can be made of plastic or other materials with certain support to reduce wear on the iron core surface, or the guide rod 22 can be used to connect the two ends of the roller 2 respectively.
[0034] The base frame 1 is fixedly installed with multiple sets of upright blocks 11. The multiple sets of upright blocks 11 are respectively connected to the ends of two guide rods 22. Each set of upright blocks 11 consists of two blocks, and the two blocks 11 are spaced apart. The ends of the guide rods 22 are embedded between the two blocks 11 to limit the guide rods 22 in a first direction.
[0035] Two retaining rings 221 are fitted at the ends of the guide rods 22. The two retaining rings 221 are fixedly connected to the guide rods 22. The two retaining rings 221 are spaced apart and are located on both sides of the upright block 11 to limit the guide rods 22 in the second direction.
[0036] In other words, each set of upright blocks 11 fixes one end of the guide rod 22 to limit the left and right directions of the guide rod 22 and prevent the guide rod 22 from moving in the left and right directions; two retaining rings 221 are located at the front and rear ends of their corresponding set of upright blocks 11 to limit the front and rear directions of the guide rod 22 and prevent the guide rod 22 from moving back and forth. The guide rod 22 is fixed by the upright blocks 11 and the retaining rings 221, so that the guide rod 22 can be easily removed from the base frame 1 or easily installed on the base frame 1. Therefore, it is possible to easily replace different types of guide rods 22 to match different types of iron cores.
[0037] A first limiting block 23 is formed on the circumferential surface of the roller 2. The first limiting block 23 is used to limit the placement position of the iron core.
[0038] In this embodiment, the first limiting block 23 is located at the rear end of the roller 2, that is, it is used to hold the rear end of the iron core, so as to position the iron core and make the detection end of the iron core closer to the supplementary light unit 3, thereby reducing the angle adjustment frequency of the supplementary light unit 3.
[0039] A second limiting block 24 is formed on the circumferential surface of the roller 2. The second limiting block 24 is used to limit the iron core in the second direction.
[0040] The first limiting block 23 and the second limiting block 24 are spaced apart, and the iron core is located between the first limiting block 23 and the second limiting block 24.
[0041] There are multiple first limiting blocks 23 arranged around the circumference of the roller 2. There are also multiple second limiting blocks 24 arranged around the circumference of the roller 2.
[0042] In this embodiment, the second limiting block 24 is used to position the front end of the iron core so that the iron core can move around its circumference and avoid deviation. Both the first limiting block 23 and the second limiting block 24 can be made of rubber.
[0043] The base frame 1 is equipped with a supplementary lighting unit 3, which is used to provide supplementary lighting in the direction of the iron core.
[0044] In this embodiment, the supplementary lighting unit 3 may include a support frame and a light source. The light source is mounted on the support frame, and the support frame is a flexible material with an adjustable angle.
