Description

Technical Field

[0001] The utility model relates to a motor stator positioning tool, belonging to the technical field of motor production equipment. Background Art

[0002] When manufacturing the motor stator, the coil must be longitudinally embedded in the stator core through a coil embedding machine. However, it is not convenient to embed the coil in one time for reasons such as the distinction between main and auxiliary phases in the stator core, and two to three embeddings are required. In order to increase the slot full height, except for the last embedding, a coil expansion machine is required to expand and compact the embedded coil after each embedding. This requires the use of a positioning mold to position the stator. Since the stator needs to be embedded several times, the stator needs to be rotated at a specific angle each time it is embedded. The existing mechanism for rotating the stator at an angle is complex and has a high manufacturing cost. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a motor stator positioning tool, which is used for positioning, placing and angular rotation of the motor stator, has a simple structure, is easy to manufacture, and can solve the shortcomings of the prior art.

[0004] The technical solution of the utility model is: a motor stator positioning tool, including a body and an arc-shaped magnet, the body includes a limiter and a support member with an arc-shaped surface distribution transfer or ball connection, the support member supports the stator and allows the stator to rotate along its own central axis, the limiters are located on both sides of the body to limit the axial direction of the stator located on the support member, the arc-shaped magnet can be attracted to the outer wall of the stator, the outer surface of the arc-shaped magnet has a plurality of evenly distributed clamping positions, the body is transferred with a clamping member, and the clamping member is engaged with the clamping position on the arc-shaped magnet by rotation.

[0005] Furthermore, a limiting member on at least one side is movably mounted on the main body, and is limited by moving on the main body to cooperate with one end of the stator located on the support member.

[0006] It further comprises a driving device, wherein at least a limiting member located on one side of the main body is slidably connected to the main body and connected to the driving device, and the driving device drives the sliding movement to cooperate with and limit one end of the stator.

[0007] Furthermore, the limiting member comprises two half-pieces which are matched and slidably connected to the main body, and the two half-pieces are driven to slide by corresponding driving devices to achieve matching / separation.

[0008] By implementing the utility model, the stator is placed on a support member with an arc-shaped surface distribution, and the limiting member limits the two ends of the stator. The stator can rotate with its own central axis. In order to fix the stator and rotate it at a specific angle, the arc-shaped magnet is attracted to the outer wall of the stator, and the clamping member is rotated to be clamped with the clamping position on the arc-shaped magnet for wire embedding. After completing one wire embedding, the stator is rotated to make the clamping member clamp with the next clamping position. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Embodiments of the present utility model: Figures 1 to 3 As shown, a motor stator positioning tool comprises a body 1 and an arc-shaped magnet 2. The body 1 comprises a limiter 3 and a ball 4 with a ball joint distributed in an arc-shaped surface. The ball 4 is the support for the stator 5 and enables the stator 5 to rotate along its own central axis. The limiters 3 are located on both sides of the body 1 to limit the axial direction of the stator 5 located on the ball 4. The limiter 3 has an arc-shaped inner wall coaxially distributed with the stator 5, and the diameter of the arc-shaped inner wall is smaller than the diameter of the stator 5. While the limiter 3 blocks the stator 5, the mold of the wire embedding machine and the expansion machine can pass through the limiter 3 to embed and expand the stator. The arc-shaped magnet 2 can be attracted to the outer wall of the stator 5. The outer surface of the arc-shaped magnet 2 has several evenly distributed clamping positions 6. The body 1 is connected with a clamping member 7. The connector 7 is engaged with the engaging position 6 on the arc-shaped magnet 2 by rotating. When in use, the stator 5 is placed on the ball 4 distributed on the arc surface, the limiter 3 limits the two ends of the stator 5, and the ball 4 rolls and supports it so that the stator 5 can rotate with its own central axis. In order to fix the stator 5 and rotate it at a specific angle, the arc-shaped magnet 2 is attracted to the outer wall of the stator 5 during embedding, and the engaging member 7 is rotated to engage it with a engaging position 7 on the arc-shaped magnet 2. The stator 5 is fixed and then the embedding is performed. After completing one embedding, the stator 5 is rotated to engage the engaging member 7 with the next engaging position 7 to realize the positioning and rotation of the stator 5. In order to make the engaging of the engaging member 7 with the arc-shaped magnet 2 more stable, the engaging member 7 is also magnetically engaged with the arc-shaped magnet 2.

[0014] As a preferred embodiment, the limit member 3 on one side is slidably connected to the main body 1, and the obstruction to the stator 5 can be released by sliding on the main body 1. Since the ball 4 rolls and supports the stator 5, the stator 5 can be easily slid out and installed from the unblocked side. The stator 5 does not need to be lifted when being removed, which facilitates the removal of the stator 5.

[0015] As a preferred embodiment, it includes a cylinder 8, which is the driving device. To facilitate the movement of the limit member 3, the cylinder 8 is installed on the main body 1 and connected to the limit member 5. The limit member 5 is pushed by the extension and contraction of the cylinder 8 to switch the limit member 5 between the blocking position and the unblocking position. To make the movement faster and more accurate and have better stability, the limit member 5 includes two halves, each of which is driven to slide by the corresponding cylinder 5. When the two halves are moved together facing each other, the stator 5 is blocked and limited, and the two halves slide in the opposite direction to unblock the stator 5.
