Description

Technical Field

[0001] The utility model relates to the field of jigs and tooling, and particularly to a jig for mounting magnetic steel of an external rotor motor. Background Art

[0002] On the inner wall of the rotor housing of an external rotor motor, equidistant magnetic steel blocks need to be attached. Currently, the jigs and equipment for attaching magnetic steel are provided by equipment suppliers, with high costs and long equipment delivery times. The debugging and maintenance of magnetic steel attachment equipment are complex and require special guidance to use. To solve the problem of magnetic steel bonding in the sample development stage, this tooling jig is made by 3D printing or CNC. The manufacturing cycle of the jig is much shorter than that of the equipment, and the cost is much lower than that of the equipment. Moreover, it is simple and easy to operate. After simple teaching, the magnetic steel attachment process can be completed, solving the problems of small batch or short sample cycle and cost control. Content of the Utility Model

[0003] The main purpose of the utility model is to provide a jig for mounting magnetic steel of an external rotor motor.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A jig for mounting magnetic steel of an external rotor motor includes a magnetic steel separation part and a magnetic steel limiting part. One end of the magnetic steel separation part is provided with the magnetic steel limiting part. The magnetic steel separation part includes a separation part base and separation strip-shaped limiting blocks. The separation part base is cylindrical, and several separation strip-shaped limiting blocks are arranged on the outer ring surface of the separation part. The outer ring surface diameter of the magnetic steel limiting part is greater than the outer ring surface diameter of the separation part base.

[0006] Further, the magnetic steel separation part and the magnetic steel limiting part are fixedly connected by screws.

[0007] Further, the outer ring surface diameter of the magnetic steel limiting part is greater than the maximum outer ring surface diameter of the magnetic steel separation part, and a sliding connection hole with the same cross-section as the length direction of the magnetic steel separation part is opened at the center of the magnetic steel limiting part. The magnetic steel separation part is slidably connected in the sliding connection hole.

[0008] Further, a pulling rod is fixedly installed at the connection end of the magnetic steel separation part and the sliding connection hole.

[0009] Further, several separation connection grooves are fixedly opened on the separation part base of the magnetic steel separation part. The distances between the separation connection grooves are the same. Separation strip-shaped limiting blocks are slidably installed in the separation connection grooves. One end of each separation strip-shaped limiting block is provided with a fixing part, and the fixing part is fixedly connected to one end of the separation part base by screws.

[0010] Further, the width of the connecting end of the partition bar-shaped limiting block and the partition base is smaller than the width of the end of the partition bar-shaped limiting block away from the partition base.

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

[0012] The present utility model forms a placement space for the magnet blocks through the partition base and the partition bar-shaped limiting block, and limits the magnet blocks in the placement space through the magnet limiting part, which is convenient for installation, saves manpower and material resources, solves the problem of long sample cycle for small batches, and controls the production cost.

[0018] The following elaborates on the preferred embodiments of the present utility model in conjunction with the drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the scope of protection of the present utility model more clearly defined.

[0019] Embodiment 1

[0020] Referring to Figure 1 As shown, an outer rotor motor magnet mounting jig includes a magnet separation part 1 and a magnet limiting part 2. One end of the magnet separation part 1 is provided with the magnet limiting part 2. The magnet separation part 1 includes a partition base 3 and a partition bar-shaped limiting block 4. The partition base 3 is cylindrical, and a plurality of partition bar-shaped limiting blocks 4 are provided on the outer ring surface of the partition part. The outer ring surface diameter of the magnet limiting part 2 is larger than the outer ring surface diameter of the partition base 3. The magnet separation part 1 and the magnet limiting part 2 are fixedly connected by screws.

[0021] The width of the connecting end of the partition bar-shaped limiting block 4 and the partition base 3 is smaller than the width of the end of the partition bar-shaped limiting block 4 away from the partition base 3.

[0022] In this embodiment, the magnetic steel limiting part 2 functions to limit the magnetic steel when it is installed in the material placing space formed between the separated strip-shaped limiting block 4 and the base of the separating part. In this way, after the magnetic steel is installed between the separated strip-shaped limiting blocks 4, this jig and the magnetic steel are inserted into the rotor housing of the outer rotor motor together. The outer ring surface of the magnetic steel just fits against the inner wall of the rotor housing, and glue is coated on the inner wall of the rotor housing to achieve the mounting. Then, this jig is withdrawn to complete the mounting.

[0023] Embodiment 2

[0024] See Figure 2 As shown, the technical features of this embodiment are substantially the same as those of Embodiment 1. The distinguishing feature is that the outer ring surface diameter of the magnetic steel limiting part 2 is larger than the maximum outer ring surface diameter of the magnetic steel separating part 1, and a sliding connection hole 5 with the same cross-section as the length direction of the magnetic steel separating part 1 is provided at the center of the magnetic steel limiting part 2, and the magnetic steel separating part 1 is slidably connected in the sliding connection hole 5.

[0025] A pulling rod 6 is fixedly installed at the connection end of the magnetic steel separating part 1 and the sliding connection hole 5.

[0026] In this embodiment, with the magnetic steel limiting part 2 functioning as a limiting function, during installation, since the maximum diameter of the magnetic steel limiting part 2 is larger than the maximum diameter of the magnetic steel separating part 1, when the magnetic steel separating part 1 is withdrawn, the problem that the magnetic steel separating part 1 pulls the magnetic steel away together due to friction is solved.

[0027] Embodiment 3

[0028] See Figure 3 As shown, the technical solution of this embodiment is substantially the same as that of Embodiment 1 or 2. The distinguishing feature is that a number of separating connection grooves 7 are fixedly provided on the separating base 3 of the magnetic steel separating part 1. The distances between the separating connection grooves 7 are the same. A separated strip-shaped limiting block 4 is slidably installed in the separating connection grooves 7. One end of the separated strip-shaped limiting block 4 is provided with a fixing part, and the fixing part is fixedly connected to one end of the separating base 3 by screws.

[0029] Through the detachability of the separated strip-shaped limiting block 4, it is realized that the separated strip-shaped limiting block 4 can be replaced separately, and the distance between the separated strip-shaped limiting blocks 4 can be adjusted, which is used for better matching installation and reducing production costs.

[0030] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. Any equivalent modification or change made by those of ordinary skill in the art according to the content disclosed by the present invention shall be included in the protection scope recorded in the claims.
