Description

Technical Field

[0001] The present application relates to the technical field of motors, and more particularly to a device for magnetizing a motor housing. Background Art

[0002] During the manufacturing process of the motor, it is necessary to place magnet sheets inside the motor casing to improve the performance of the motor, such as adjusting the magnetic field inside the motor to improve the performance of the motor, ensuring the uniformity of the magnetic field inside the motor, thereby reducing the vibration and electromagnetic noise inside the motor, and improving the efficiency of the motor.

[0003] However, the raw material of the magnet sheet is often a strip magnet sheet, but due to the limitation of the internal shape of the motor housing, the magnet sheet placed inside the motor housing needs to be a ring magnet sheet. Therefore, the strip magnet sheet needs to be pressed into a ring magnet sheet before it can be assembled with the motor housing.

[0004] During the production process of the motor, magnet sheets of different sizes need to be assembled into motor casings of different models, but the cost of using different production lines to produce magnet sheets for assembly with motor casings of different models is too high. Utility Model Content

[0005] In order to reduce the production cost required for producing magnet sheets for assembly with motor casings of different models, the present application provides a device for magnetizing a motor casing.

[0006] The present application provides a motor housing magnetizing sheet device that adopts the following technical solution:

[0007] A device for applying a magnetic sheet to a motor housing, comprising:

[0008] The rack is fixedly connected to the ground to provide an installation environment;

[0009] A magnet positioning mechanism, mounted on the frame, and used for positioning the stacked bar magnet sheets;

[0010] The magnet deformation mechanism comprises a deformation block, which is arranged close to the magnet positioning mechanism. A deformation cavity for limiting the deformation of the strip magnet sheet is provided in the deformation block, and the deformation block is detachably connected to the frame.

[0011] By adopting the above technical solution, during the production process of the motor, the frame provides an installation environment for the mechanism used in the production process of the motor. The strip magnet sheet is placed on the frame through the magnet positioning mechanism, which is convenient for continuous processing of the strip magnet sheet, and the strip magnet sheet is deformed into a ring magnet sheet through the deformation cavity in the magnet deformation mechanism, thereby facilitating the assembly of the magnet sheet and the motor housing. At the same time, the detachably connected deformation block can be replaced with a different type of deformation block according to the different types of magnet sheets, so that different types of motor housings and magnet sheets can be assembled through one production line, reducing the production cost required for producing magnet sheets to be assembled with different types of motor housings.

[0012] Optionally, a magnet sheet outlet connected to the deformation cavity is provided at one end of the deformation block, a stepped groove is provided at the end of the deformation block where the magnet sheet outlet is provided, a through hole is provided on the frame, and the hole wall of the through hole abuts against the groove wall of the stepped groove.

[0013] By adopting the above technical solution, the step groove opened at the bottom end of the deformation block can be matched with the through hole on the frame, so as to realize the detachable connection between the deformation block and the frame. When installing the deformation block, the connection between the deformation block and the frame is realized by inserting the step groove into the through hole. When replacing the deformation block of different types, the deformation block of different types can be replaced by pulling the deformation block out of the through hole.

[0014] Optionally, one side of the frame connected to the deformation block is connected with an abutment frame and a plurality of abutment cylinders, one end of the abutment frame is fixedly connected to the frame, the other end of the abutment frame is located at the end of the deformation block away from the through hole, the fixed end of the abutment cylinder is fixedly connected to the end of the abutment frame away from the deformation block, and the telescopic end of the abutment cylinder can abut the end of the deformation block away from the through hole.

[0015] By adopting the above technical solution, after the deformation block is placed in the through hole, the abutment frame provides support for the abutment cylinder, so that the abutment cylinder can be extended and retracted in the direction of the deformation block, thereby pressing the deformation block against the frame, reducing the probability of the deformation block shaking on the frame due to deformation, thereby improving the processing accuracy of the magnet sheet.

[0016] Optionally, the magnet positioning mechanism includes an abutment plate, a first limit plate, a second limit plate and a pushing piece, the abutment plate is fixedly connected to the frame, the first limit plate and the second limit plate are both spaced apart from the abutment plate, the first limit plate is arranged close to the deformation block, the first limit plate is slidably connected to the frame, the second limit plate is arranged parallel to the first limit plate and spaced apart, the second limit plate is located on the side of the first limit plate away from the deformation block, and the pushing piece is used to push the strip magnet sheet located between the first limit plate and the second limit plate to abut the abutment plate.

[0017] By adopting the above technical solution, the strip magnet sheets are placed between the first limiting plate and the second limiting plate, and then the pushing member pushes the stacked strip magnet sheets to abut the abutting plate, so that the strip magnet sheets can enter the deformation block in sequence, thereby realizing the sequential deformation of the stacked strip magnet sheets. When processing magnet sheets of different models, the distance between the first limiting plate and the abutting plate is adjusted by sliding the first limiting plate, so that the strip magnet sheets of different models can enter the deformation cavity of the deformation block from between the abutting plate and the first limiting plate.

[0018] Optionally, the magnet deformation mechanism also includes a magnet extrusion part, and a deformation entrance connected to the deformation cavity is opened on the side of the deformation block facing the abutment plate. The magnet extrusion part is used to squeeze the strip magnet sheet in the magnet positioning mechanism into the deformation entrance and provide power for the strip magnet sheet to be deformed into a ring-shaped magnet sheet.

[0019] By adopting the above technical solution, the strip magnet sheet is squeezed into the deformation cavity by the magnet extrusion piece facing the deformation entrance, so that the strip magnet sheet is deformed into an annular magnet sheet under the joint action of the magnet extrusion piece and the deformation cavity.

[0020] Optionally, the magnet extrusion component includes an extrusion cylinder and an extrusion block, the extrusion cylinder is located on the side of the second limit plate away from the first limit plate, the telescopic end of the extrusion cylinder is arranged toward the deformation block and connected to the extrusion block, and the extrusion block is used to abut the strip magnet sheet.

[0021] By adopting the above technical solution, when the magnet extrusion part is working, the extrusion block is driven to move in the direction of the deformation block by the extension and contraction of the extrusion cylinder, thereby pushing the strip magnet sheet located between the first limit plate and the second limit plate toward the deformation entrance, so that the strip magnet block is deformed into a ring-shaped magnet block.

[0022] Optionally, the extrusion block is provided with a sliding through hole along the direction of the deformation block, the sliding through hole is sleeved on the abutment plate, the thickness of the extrusion block on the side of the abutment plate abutting the strip magnet sheet is at most the thickness of a strip magnet sheet, and the moving direction of the extrusion block is toward the deformation entrance.

[0023] By adopting the above technical solution, when the extrusion block moves, the extrusion block slides toward the deformation entrance along the direction of the abutment plate through the sliding through hole on the extrusion block, and the strip magnet sheet abutting the abutment plate is pushed toward the deformation entrance by the part of the abutment plate close to the strip magnet sheet, so that the strip magnet sheet enters the deformation cavity.

[0024] Optionally, a limiting abutment plate is arranged on the frame, and the limiting abutment plate is located on a side of the first limiting plate away from the second limiting plate, and the limiting abutment plate can move toward the first limiting plate and frictionally abut against the first limiting plate.

[0025] By adopting the above technical solution, when adjusting the first limit plate, the limit abutment plate can be separated from the first limit plate so that the first limit plate can slide on the frame. When the first limit plate slides to the desired position on the frame, the limit abutment plate is moved toward the first limit plate so that the limit abutment plate frictionally abuts against the first limit plate, thereby completing the determination of the position of the first limit plate.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. During the production process of the motor, the strip magnet sheet is placed on the frame through the magnet positioning mechanism, and the strip magnet sheet is deformed into a ring magnet sheet in the deformation cavity of the deformation block through the magnet deformation mechanism, so as to facilitate the assembly of the magnet sheet and the motor housing. By detachably connecting the deformation block to the frame, different deformation blocks can be replaced, so that the strip magnet sheet is deformed into ring magnet sheets of different sizes, which is convenient for assembly with motor housings of different models, and reduces the production cost required to produce magnet sheets for assembly with motor housings of different models;

[0028] 2. When the deformation block is connected to the frame, the stepped groove of the deformation block is clamped into the through hole on the frame to achieve a detachable connection between the deformation block and the frame, and the deformation block is abutted against the frame by the abutting cylinder to achieve the positioning of the deformation block. When replacing the deformation block, first separate the abutting cylinder from the deformation block, then pull the deformation block out of the through hole, and then replace it with the required deformation block, so that the stepped groove wall of the deformation block abuts against the hole wall of the through hole, and then adjust the abutting cylinder so that the abutting cylinder abuts against the end of the deformation block away from the through hole, and the replacement of the deformation block is completed;

[0029] 3. Place the strip magnet sheets on the frame through the first limiting plate and the second limiting plate. When processing strip magnet sheets of different types, slide the first limiting plate on the frame so that the strip magnet sheets of different types can pass through the gap between the first limiting plate and the abutting plate, and enter the deformation cavity, thereby realizing the processing of magnet sheets of different types.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-3 This application is described in further detail.

[0035] The present application discloses a device for applying magnets to a motor housing. Figure 1 and Figure 2 A device for magnetically punching a motor casing includes a frame 1, a magnet positioning mechanism 2 and a magnet deformation mechanism 3.

[0036] The frame 1 is fixedly connected to the ground, and the magnet positioning mechanism 2 is installed at one end of the frame 1 away from the ground. The magnet positioning mechanism 2 is used to position the stacked bar magnet sheets. The magnet deformation mechanism 3 includes a deformation block 31, which is arranged close to the magnet positioning mechanism 2. A deformation cavity 311 for limiting the deformation of the bar magnet sheet is provided in the deformation block 31. A deformation inlet 314 connected to the deformation cavity 311 is provided at one end of the deformation block 31 facing the magnet positioning mechanism 2. The deformation block 31 is detachably connected to the frame 1.

[0037] During the motor production process, the strip magnet sheet located in the magnet positioning mechanism 2 is moved into the deformation cavity 311 of the deformation block 31 through the deformation entrance 314 through the magnet deformation mechanism 3, so that the strip magnet sheet is deformed into an annular magnet sheet, thereby facilitating the assembly of the magnet sheet and the motor housing. At the same time, by replacing different deformation blocks 31 when processing motors of different models, different types of annular magnet sheets can be processed to realize the assembly of motors of different models, thereby reducing the production cost required for producing magnet sheets to be assembled with motor housings of different models.

[0038] Reference Figure 1 and Figure 3 The magnet positioning mechanism 2 includes an abutment plate 21, a first limiting plate 22, a second limiting plate 23 and a push member 24. One end of the abutment plate 21 is fixedly connected to the frame 1. The layout direction of the abutment plate 21 faces the direction of the deformation entrance 314. The first limiting plate 22 and the second limiting plate 23 are spaced apart from the abutment plate 21. The first limiting plate 22 is arranged close to the deformation block 31 and is perpendicular to the layout direction of the abutment plate 21. The bottom end of the first limiting plate 22 is slidably connected to the frame 1. The second limit plate 23 is arranged parallel to the first limit plate 22 and spaced apart. The second limit plate 23 is located on the side of the first limit plate 22 away from the deformation block 31. The pushing member 24 is located on the side of the abutment plate 21 away from the deformation block 31. The pushing member 24 includes a pushing cylinder 241 and a pushing plate 242 arranged toward the abutment plate 21. The pushing cylinder 241 is fixedly connected to the frame 1, and the pushing plate 242 is fixedly connected to the telescopic end of the pushing cylinder 241 toward the abutment plate 21.

[0039] During the operation of the magnet positioning mechanism 2, the strip magnet sheets are stacked and placed between the first limiting plate 22 and the second limiting plate 23, and then the strip magnet sheets are pushed toward the abutment plate 21 by the pushing member 24, so that the strip magnet sheets abut against the abutment plate 21, thereby facilitating the strip magnet sheets abutting against the abutment plate 21 to enter the interior of the deformation block 31 through the gap between the abutment plate 21 and the first limiting plate 22.

[0040] Reference Figure 1 and Figure 3 A limit plate 6 is arranged on the frame 1, and the limit plate 6 is located on the side of the first limit plate 22 away from the second limit plate 23. The end of the limit plate 6 away from the first limit plate 22 is connected to a telescopic rod 7, and the fixed end of the telescopic rod 7 is fixedly connected to the frame 1. A telescopic spring is arranged inside the telescopic rod 7. A friction protrusion is arranged on the side of the limit plate 6 facing the first limit plate 22 and can abut the first limit plate 22.

[0041] When processing bar magnet sheets of different thicknesses, it is necessary to adjust the gap size between the first limit plate 22 and the abutment plate 21. When adjusting the gap between the first limit plate 22 and the abutment plate 21, the limit abutment plate 6 is separated from the first limit plate 22, and then the first limit plate 22 is moved away from or close to the abutment plate 21, thereby adjusting the gap between the first limit plate 22 and the abutment plate 21. When the gap between the first limit plate 22 and the abutment plate 21 is adjusted to the required size, the limit abutment plate 6 will abut against the first limit plate 22, thereby maintaining the gap between the first limit plate 22 and the abutment plate 21 at the required gap size.

[0042] Reference Figure 1 and Figure 2 The magnet deformation mechanism 3 further includes a magnet extrusion member 32, and the deformation entrance 314 is located on the side of the deformation block 31 facing the abutment plate 21. The magnet extrusion member 32 is arranged close to the abutment plate 21 and can move toward the deformation entrance 314. The magnet extrusion member 32 includes an extrusion cylinder 321 and an extrusion block 322. The extrusion cylinder 321 is located on the side of the second limit plate 23 away from the first limit plate 22. The telescopic end of the extrusion cylinder 321 is arranged toward the deformation block 31 and fixedly connected to the extrusion block 322. The extrusion block 322 is used to abut the strip magnet sheet.

[0043] When the magnet extrusion piece 32 is working, the extrusion cylinder 321 drives the extrusion block 322 to slide toward the deformation entrance 314, so that the extrusion block 322 abuts against the strip magnet sheet abutting the abutment plate 21, thereby driving the strip magnet sheet to move toward the deformation entrance 314 and finally enter the deformation entrance 314.

[0044] Reference Figure 1 and Figure 3 The extrusion block 322 is provided with a sliding hole 3221 along the direction of the deformation block 31, and the sliding hole 3221 is sleeved on the abutment plate 21. The thickness of the extrusion block 322 located on the side of the abutment plate 21 abutting against the strip magnet sheet is at most the thickness of a strip magnet sheet, and the moving direction of the extrusion block 322 is toward the deformation entrance 314.

[0045] When the extrusion block 322 moves, the sliding through hole 3221 is sleeved on the abutment plate 21, thereby limiting the movement direction of the extrusion block 322, and the part of the extrusion block 322 located on the abutment plate 21 close to the first limiting plate 22 can abut against the strip magnet sheet abutting the abutment plate 21, thereby driving the strip magnet sheet to move toward the deformation entrance 314.

[0046] Reference Figure 2 and Figure 3A magnet sheet outlet 312 connected to the deformation cavity 311 is provided at one end of the deformation block 31, and a stepped groove 313 is provided at one end of the deformation block 31 where the magnet sheet outlet 312 is provided. A through hole 12 is provided on the frame 1, and the hole wall of the through hole 12 abuts against the groove wall of the stepped groove 313.

[0047] A stepped groove 313 is provided on the deformation block 31, and the stepped groove 313 is connected to the through hole 12 on the frame 1 to realize the detachable connection between the deformation block 31 and the frame 1, thereby facilitating the use of different types of deformation blocks 31 to process different types of magnet sheets.

[0048] Reference Figure 1 The side of the frame 1 connected to the deformation block 31 is connected with an abutting frame 4 and a plurality of abutting cylinders 5. The number of the abutting cylinders 5 is preferably 4 and abuts against the four corners of the deformation block 31. One end of the abutting frame 4 is fixedly connected to the frame 1, and the other end of the abutting frame 4 is located at the end of the deformation block 31 away from the through hole 12. The fixed end of the abutting cylinder 5 is fixedly connected to the end of the abutting frame 4 away from the deformation block 31, and the telescopic end of the abutting cylinder 5 can abut against the end of the deformation block 31 away from the through hole 12.

[0049] The abutment frame 4 is arranged on the frame 1, and the abutment cylinder 5 installed on the abutment frame 4 abuts against the end of the deformation block 31 away from the through hole 12, thereby reducing the probability of the deformation block 31 shaking on the frame 1. When replacing the deformation block 31, the abutment cylinder 5 is separated from the deformation block 31, and then the deformation block 31 is taken out from the through hole 12, and then the replaced deformation block 31 is placed in the through hole 12, and the abutment cylinder 5 is abutted against the replaced deformation block 31, so that the replacement of the deformation block 31 is completed.

[0050] The implementation principle of a motor casing magnetizing sheet device according to an embodiment of the present application is as follows: during the production process of the motor, a strip-shaped magnet sheet is positioned on the frame 1 by a magnet positioning mechanism 2, and then the strip-shaped magnet sheet is deformed into a ring-shaped magnet sheet by a deformation block 31 in a magnet deformation mechanism 3, thereby facilitating the assembly of the magnet sheet and the motor casing. Through the detachable connection between the deformation block 31 and the frame 1, different types of magnet sheets and the motor casing can be assembled by replacing different deformation blocks 31, so that different types of motor casings and magnet sheets can be assembled on one assembly line, thereby reducing the production cost required to produce magnet sheets for assembly with different types of motor casings.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
