Description

Technical Field

[0001] This utility model relates to the field of magnet installation technology, specifically a magnet separation auxiliary device. Background Technology

[0002] During the assembly of a built-in permanent magnet synchronous motor, several magnets need to be inserted one by one into the corresponding slots on the rotor. During magnet production, to facilitate effective separation of the magnets later, a plastic separator is typically placed between two adjacent magnets. Multiple magnets and separators arranged at intervals form a magnet bar (e.g., ...). Figure 3 As shown, when inserting magnets into the rotor slots, the magnets on the magnet bar need to be separated one by one and then inserted into the corresponding slots. Currently, the magnets on the magnet bar are separated manually by prying them off one by one with fingers. After a long period of manual labor, the fingers will feel sore, and the efficiency of manually prying magnets off with fingers is low, which in turn affects the rotor assembly efficiency.

A separation gap is set between the right side wall of the guide rail and the left side wall of the positioning plate. The separation plate is clamped in the separation gap, and the rear end of the separation plate is hinged to the left side wall of the positioning plate. The hinge point between the separation plate and the positioning plate is located at the lower rear side of the guide rail. When the separation plate is placed horizontally, the upper surface of the separation plate is located below the bottom surface of the square groove. The separation plate can push the magnetic steel or magnetic steel plastic isolation plate located in the separation gap out of the separation gap by swinging once.

Detailed Implementation

[0018] The following will describe specific embodiments and appendices. Figure 1-3 The technical solutions in the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some preferred embodiments of this utility model, and not all embodiments. Those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0019] This utility model provides a magnetic steel separation auxiliary device (such as...) Figure 1As shown, the auxiliary device includes a guide rail 1, a positioning plate 2, a separation plate 3, and a support plate 4. The support plate 4 supports the entire auxiliary device. Moving the support plate 4 allows for easy movement of the auxiliary device as a whole, enabling flexible movement according to usage requirements in practical applications. To increase the friction between the support plate 4 and the support plate surface during use, thereby improving the stability of the device, a rubber plate can be installed at the bottom of the support plate 4. The guide rail 1 is mounted on the support plate 4 via a support base 5. A square groove 11 extending horizontally through the guide rail 1 is provided on the upper part of the guide rail 1. In practical applications, the square groove 11 is used for... To prevent the magnet from swaying, the positioning plate 2 is mounted on the support plate 4 and located to the right of the guide rail 1. A separation gap 6 is provided between the right side wall of the guide rail 1 and the left side wall of the positioning plate 2. The separation plate 3 is clamped within the separation gap 6, and the rear end of the separation plate 3 is hinged to the left side wall of the positioning plate 2. In practical applications, the separation plate 3 can swing back and forth within the separation gap 6 around the hinge axis. The hinge point between the separation plate 3 and the positioning plate 2 is located on the lower rear side of the guide rail 1. The purpose of the above-mentioned hinge arrangement between the separation plate 3 and the positioning plate 2 is to prevent the separation plate 3 from swinging back and forth during the back and forth movement of the positioning plate 2. During the process, the separating plate 3 ensures that the magnet 71 or the magnetic plastic isolation plate 72 located in the separating gap 6 is pushed out of the separating gap 6, thereby achieving effective separation of the magnet 71 or the magnetic plastic isolation plate from the magnet row 7. When the separating plate 3 is in a horizontal position, the upper surface of the separating plate 3 is below the bottom surface of the square groove 11. When the separating plate 3 is in a horizontal position, it can prevent it from obstructing the magnet 71 or the magnetic plastic isolation plate 72 on the magnet row 7 from entering the separating gap 6. At the same time, it also ensures that the separating plate 3 is below the magnet 71 or the magnetic plastic isolation plate 72 in the separating gap 6 before swinging, so as to ensure that the separating plate 3 is below the magnet 71 or the magnetic plastic isolation plate 72 in the separating gap 6. The effective pushing of the separation plate 3 or the magnetic steel plastic isolation plate 72 allows the separation plate 3 to swing once, pushing the magnetic steel 71 or the magnetic steel plastic isolation plate 72 located in the separation gap 6 out of the separation gap 6. A material picking notch 21 is provided on the upper front side of the positioning plate 2. When the separation plate 3 pushes the magnetic steel 71 forward towards the positioning plate 2, as the separation plate 3 swings continuously, a part of the magnetic steel 71 moves from the separation gap 6 to the side of the material picking notch 21, thereby exposing part of the magnetic steel 71. This makes it easier for the operator to use the exposed part of the magnetic steel 71 to remove the magnetic steel 71, and then smoothly install the magnetic steel 71 on the motor rotor. The separation plate 3 can effectively separate the magnetic steel 71 from the magnetic steel row 7, thereby improving the separation efficiency of each magnetic steel 71 on the magnetic steel row 7, which in turn helps to improve the rotor assembly efficiency. At the same time, the separation of the magnetic steel 71 for a long time will not cause pain to the fingers, thus improving the comfort of operation.

[0020] In practical applications, the thickness of the magnet 71 is generally greater than the thickness of the magnetic plastic isolation plate 72. The thickness of the magnet 71 is generally around 3mm, and the thickness of the magnetic plastic isolation plate 72 is generally around 2mm. To facilitate effective separation of the magnet 71 or the magnetic plastic isolation plate 72 using the separation plate 3, the right side wall of the separation plate 3 is made to fit against the left side wall of the positioning plate 2. The separation plate 3 remains in contact with the positioning plate 2 during the swinging process. The thickness of the separation plate 3 is less than the thickness of the magnetic plastic isolation plate 72. The front-to-back distance of the separation gap 6 is 0.5mm greater than the thickness of the magnet 71. The gap distance of the separation gap 6 is greater than the thickness of the magnet 71, thus ensuring that the side wall of the magnet 71 and the side wall of the positioning plate 2 are in contact. After bonding, the magnet 71 is completely located within the separation gap 6. At the same time, the portion of the magnetic plastic isolation plate 72 that is bonded to the magnet 71 is locked in the square groove 11. Thus, when the separation plate 3 is rotated, it can only push the magnet 71 within the separation gap 6. When the side wall of the magnetic plastic isolation plate 72 is bonded to the side wall of the positioning plate 2, the magnetic plastic isolation plate 72 is completely located within the separation gap 6. At the same time, the portion of the magnet 71 that is bonded to the magnetic plastic isolation plate 72 is locked in the square groove 11. Since the thickness of the separation plate 3 is less than the thickness of the magnetic plastic isolation plate 72, when the separation plate 3 is rotated, it can only push the magnetic plastic isolation plate 72 to move, thereby realizing the ejection of the magnetic plastic isolation plate 72.

[0021] Based on the above embodiments, the specific implementation method for setting the guide rail 1 on the support plate 4 using the support base 5 is as follows: a support base 5 is set at the lower part of both the left and right ends of the guide rail 1. The support base 5 is ⊥-shaped and is set on the support plate 4 by bolt connection. Specifically, a through hole is opened on the front and rear sides of the support base 5, and a threaded hole is opened on the support plate 4 to cooperate with the through hole. The support base 5 is fixedly installed on the support plate 4 by tightening the bolt through the through hole into the corresponding threaded hole. A locking groove is set at the upper part of the support base 5, and the guide rail 1 is locked in the locking groove. A top-pressing bolt 51 is set on the outside of the locking groove. The top-pressing bolt 51 is used to position the guide rail 1. When the top-pressing bolt 51 is loosened, the position of the guide rail 1 can be adjusted, thereby adjusting the size of the separation gap 6, thereby realizing the separation of magnets 71 of different thicknesses.

[0022] In practical applications, to facilitate the pushing of the separation plate 3, a handle 31 is fitted onto the outer end of the separation plate 3. The handle 31 can be cylindrical and made of nylon.

[0023] Based on the above embodiments, the specific implementation method for fixing the positioning plate 2 on the support plate 4 is as follows: two threaded holes are provided at the bottom of the positioning plate 2, and two countersunk holes corresponding to the threaded holes are provided on the support plate 4. A bolt passes through the countersunk hole and is tightened in the corresponding threaded hole to fix the positioning plate 2 on the support plate 4.

[0024] Based on the above embodiments, the specific implementation method for the hinged connection between the separation plate 3 and the positioning plate 2 is as follows: the rear end of the separation plate 3 is hinged to the left side of the positioning plate 2 using a hinged hole bolt 32. A corresponding threaded countersunk hole is provided on the positioning plate 2. The hinged hole bolt 32 passes through the through hole at the rear end of the separation plate 3 and is directly screwed into the threaded countersunk hole, thereby realizing the hinged installation of the separation plate 3.

[0025] In practical applications, to facilitate the automatic movement of the magnet bar 1 towards the positioning plate 2 by magnetic attraction during the separation of magnet 71, the positioning plate 2 can be made of steel. At the same time, to avoid the magnetic attraction between the guide rail 1 and the magnet bar 1 hindering the longitudinal movement of the magnet bar 7 in the guide rail 1, the guide rail 1 can be made of nylon or aluminum alloy. When the guide rail 1 is made of steel, to reduce the magnetic attraction between the magnet bar 7 and the guide rail 1, a layer of aluminum foil can be adhered to the outer wall of the guide rail 1. The low magnetic permeability of the aluminum foil reduces the magnetic attraction between the magnet bar 7 and the guide rail 1.

[0026] The method for separating the magnets 71 one by one in the magnet bar 7 using this utility model is as follows: First, the separating plate 3 is positioned at its lowest point. Then, a row of magnet bars 7 is placed in the square groove 11 of the guide rail 1, with the end face of the magnet bar 7 adhering to the side wall of the positioning plate 2. After the magnet bar 7 is placed, the separating plate 3 is swung upward using the handle 31. As the separating plate 3 rotates, the magnets 71 or the magnet isolation plastic plate 72 adhering to the side wall of the positioning plate 2 are pushed out, thereby separating the magnets 71. Alternatively, the separation of the magnetic steel isolation plastic plate 72 can occur. As the separation plate 3 continues to move, the separation plate 3 disengages from the separation gap 6 area. At this time, the end face of the magnetic steel row 7 is once again attached to the side wall of the positioning plate 2 under magnetic attraction or manual pushing. Then, the separation plate 3 is rotated in the opposite direction. During the reverse rotation of the separation plate 3, the magnetic steel 71 or the magnetic steel isolation plastic plate 72 is pushed out of the separation gap 6 again. By using the handle 31 to make the separation plate 3 swing back and forth, the magnetic steel 71 can be separated from the magnetic steel row 7 one by one.

However, the present invention is not limited to the above embodiments and examples. For those skilled in the art, several improvements and modifications can be made without departing from the concept of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
